The present application relates to the technical field of electronic devices, and in particular to an earphone.
With the increasing popularity of electronic devices, electronic devices have become indispensable social and entertainment tools in people's daily life, and their requirements for electronic devices are also increasing. Electronic devices such as earphones and smart glasses have also been widely used in people's daily life, which can be used with terminal devices such as mobile phones and computers to provide users with an auditory feast. For earphones, it is difficult to consider both stability and comfort in terms of wearing.
The embodiments of the present disclosure provide an earphone. The earphone may include a core module and a hook structure connected with the core module. The core module may be disposed at a front side of an ear in a wearing state. At least a portion of the hook structure may be disposed at a rear side of the ear in the wearing state. An orthographic projection of the hook structure and an orthographic projection of the core module on a reference plane perpendicular to a thickness direction may not overlap. The thickness direction may be a direction in which the core module is close to or away from the ear in the wearing state. The hook structure may include a battery housing and a flexible coating. A battery coupled with the core module may be disposed in the battery housing. The battery housing may include a cover housing and a battery compartment connected with the cover housing. The flexible coating may cover the cover housing. A first reference line segment with the shortest length may be provided between the orthographic projection of the hook structure and the orthographic projection of the core module. A point at which the first reference line segment intersects with the orthographic projection of the hook structure may be located in a section where the flexible coating overlaps with the cover housing.
In some embodiments, the earphone may have a second reference line parallel to the first reference line segment on the reference plane. The second reference line may intersect with an orthographic projection of the battery housing and is farthest from the first reference line segment. An edge of one side of the orthographic projection of the hook structure toward the core module may have a maximum distance to the second reference line. The maximum distance may be in a range of 34 mm-52 mm.
In some embodiments, in the wearing state, a spacing between a free end of the hook structure not connected with the core module and an upper ear root of the ear on a vertical axis of a human body may be in a range of 37 mm-56 mm.
In some embodiments, in the wearing state, a spacing between the free end of the hook structure not connected with the core module and an edge of an earlobe of the ear on the vertical axis of the human body may be less than or equal to 10 mm.
In some embodiments, a length of the battery compartment in a length direction of the hook structure may be in a range of 10 mm-20 mm.
In some embodiments, one end of the battery compartment in the length direction of the hook structure may have an open end, the cover housing may be partially embedded in the open end of the battery compartment to cooperate with the battery compartment to form a cavity structure for accommodating the battery. An area of an outer surface of the cover housing on a reference cross-section perpendicular to the length direction of the hook structure may be less than an area of an outer surface of the battery compartment on the reference cross-section. The flexible coating may not cover the battery compartment.
In some embodiments, the hook structure may include an elastic metal wire configured to connect the core module and the cover housing. The area of the outer surface of the cover housing on the reference cross-section may be between a cross-sectional area of the elastic metal wire and the area of the outer surface of the battery compartment on the reference cross-section, and the area of the outer surface of the cover housing may gradually increase in a positive direction which is along the length direction of the hook structure and points from the cover housing to the battery compartment.
In some embodiments, a shape of the battery compartment may be a hollow cylinder. The area of the outer surface of the battery compartment on the reference cross-section may be in a range of 60 mm2-100 mm2.
In some embodiments, a diameter of the elastic metal wire may be in a range of 0.6 mm-0.8 mm.
In some embodiments, a free end of the core module not connected with the hook structure may extend into a cavity of auricular concha of the ear in the wearing state. The cover housing and the core module may jointly clamp an ear region corresponding to the cavity of auricular concha from a front side and a rear side of the ear region through the flexible coating.
In some embodiments, the core module may include an inner side surface facing the ear and an outer side surface away from the ear along the thickness direction in the wearing state. In a non-wearing state, at least a portion of the battery housing may be disposed between the inner side surface and the outer side surface in the thickness direction.
In some embodiments, the core module may include a core housing connected with the hook structure and a loudspeaker disposed in the core housing. One side of the core housing facing the ear in the wearing state may be provided with a sound outlet hole. A sound wave generated by the loudspeaker may be propagated through the sound outlet hole. The core module may cooperate with the cavity of auricular concha to form an auxiliary cavity communicated with an external ear canal of the ear in the wearing state. The sound outlet hole may be at least partially disposed in the auxiliary cavity.
In some embodiments, the auxiliary cavity may be semi-open.
The beneficial effects of the present disclosure include but not limited to the following content. According to the earphone provided by the present disclosure, the core module and at least a portion of the hook structure are respectively located on the front and rear sides of the ear in the wearing state, so as to allow the earphone to be worn on the ear. The hook structure contacts the rear side of the ear through the cover housing and the flexible coating thereon, and then jointly clamps the ear together with the core module, which is conducive to improving the wearing comfort of the earphone, thereby realizing both wearing stability and comfort.

In some embodiments, different users may have individual differences, resulting in different shapes, sizes, and other dimensional differences in the ears. For ease of description and reducing (or even eliminate) individual differences of different users, a simulator containing the head and (left and right) ears thereof prepared based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BCKEMAR, HEAD Acoustics, B&K 4128 series, or B&K 5128 series, may be manufactured to present a situation that most users wear an earphone 10. Taking GRAS KEMAR as an example, an ear simulator may be any one of GRAS 45AC, GRAS 45BC, GRAS 45CC, or GRAS 43AG. Taking HEAD Acoustics as an example, an ear simulator may be any one of HMS II.3, HMS II.3 LN, or HMS II.3LN HEC. Therefore, in the present disclosure, descriptions such as “wearing by the user”, “in the wearing state” and “in wearing” refer to that the earphone described in the present disclosure is worn on the ear of the simulator. Considering the individual differences of different users, there may be certain differences in case the earphone is worn by different users and the earphone is worn on the ear of the simulator. However, such differences are tolerable.
It should be noted that in the fields of medicine and anatomy, three basic planes including a sagittal plane, a coronal plane, and a horizontal plane, and three basic axes including a sagittal axis, a coronal axis, and a vertical axis of a human body may be defined. The sagittal plane refers to a section perpendicular to the ground along a front-back direction of the body, which divides the human body into left and right parts. The coronal plane refers to a section perpendicular to the ground along a left-right direction of the body, which divides the human body into front and rear parts. The horizontal plane refers to a section parallel to the ground along a vertical direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis that is along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis that is along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis that is along the vertical direction of the body and perpendicular to the horizontal plane. Further, the “front side of the ear” in the present disclosure is a concept relative to the “rear side of the ear”. The “front side of the ear” refers to a side of the ear away from the head, and the “rear side of the ear” refers to a side of the ear facing the head. Both the “rear side of the ear” and the “front side of the ear” are directed to the ear of the user. A schematic diagram illustrating a front side contour of the ear as shown in

In order to improve the stability of the earphone 10 in the wearing state, the earphone 10 may adopt any one of the following modes or a combination thereof. Firstly, at least a portion of the hook structure 12 may be configured as a conformal structure that fits at least one of the rear side of the ear and the head, so as to increase a contact area between the hook structure 12 and the ear and/or the head, thereby increasing the resistance of the earphone 10 to falling off from the ear. Secondly, at least a portion of the hook structure 12 may be configured as an elastic structure such that the hook structure 12 may have a certain amount of deformation in the wearing state, thereby increasing the positive pressure of the hook structure 12 on the ear and/or the head, and increasing the resistance of the earphone 10 to fall off the ear. Thirdly, at least a portion of the hook structure 12 may be configured to abut against the head in the wearing state, so as to form a reaction force that presses the ear to the core module 11 against the front side of the ear, thereby increasing the resistance of the earphone 10 to fall off the ear. Fourthly, the core module 11 and the hook structure 12 may be configured to clamp physiological parts such as an antihelix region, a region of the cavity of auricular concha, etc., from the front and rear sides of the ear in the wearing state, thereby increasing the resistance of the earphone 10 to fall off the ear. Fifthly, the core module 11 or an auxiliary structure connected therewith may be configured to at least partially extend into physiological parts such as the cavity of auricular concha, the cymba conchae, the triangular fossa, the scapha, etc., thereby increasing the resistance of the earphone 10 to fall off the ear.
In some embodiments, referring to
It should be noted that in the wearing state, the free end FE of the core module 11 may extend into the cavity of auricular concha, and an orthographic projection of the free end FE of the core module 11 may fall onto an antihelix or left and right sides of the head and located on a front side of the ear on the sagittal axis of the human body. In other words, the hook structure 12 may be configured to support the core module 11 to be worn to a wearing position such as the cavity of auricular concha, the antihelix, the front side of the ear, etc.
In some embodiments, referring to
It should be noted that in the wearing state and viewed along the direction of the coronal axis, the core module 11 may be set as a circle, an ellipse, a rounded square, a rounded rectangle, or the like. When the core module 11 is set as a circle, an ellipse, or the like, the connection surface refers to an arc side surface of the core module 11; and when the core module 11 is set as a rounded square, a rounded rectangle, or the like, the connection surface may include a lower side surface LS, an upper side surface US, and a rear side surface RS described below. In some embodiments, the core module 11 may include the length direction Y and the width direction Z that are perpendicular to the thickness direction X and orthogonal to each other. The length direction Y is defined as a direction in which the core module 11 is close to or away from the back of the head of the user in the wearing state. The width direction Z is defined as a direction in which the core module 11 is close to or away from the top of the head of the user in the wearing state. Therefore, for the convenience of description, this embodiment takes the core module 11 as a rounded rectangle as an example for exemplary description. A length of the core module 11 in the length direction Y may be greater than a width of the core module 11 in the width direction Z.

It should be noted that the above overall curvature may be used to qualitatively describe the curvature of different sections of the hook structure 12. A curvature radius of each of different sections may be a constant value or continuously variable. Therefore, there is at least one point in the first section S1 of which the curvature radius is less than the curvature radius of each point in the second section S2. In some embodiments, the above overall curvature may also be quantitatively characterized by an average curvature radius, i.e., the curvature radiuses of N points in each section may be obtained and then an average value of the curvature radiuses of N points may be obtained.
In some embodiments, in an extension direction of the hook structure 12, a length of the second section S2 may be greater than a length of the first section S1, such that the hook structure 12 and the core module 11 may clamp the ear together to increase a contact area between the hook structure 12 and the skin of the user, which is conducive to improving the stability of the earphone 10 in the wearing state.
In some embodiments, the earphone 10 may have a first reference line segment RL1 parallel to the width direction Z. A starting point of the first reference line segment RL1 may be a point where the first reference line segment RL1 intersects with the upper side surface US, and an end point of the first reference line segment RL1 may be the dividing point DP. A second reference line segment RL2, a third reference line segment RL3, and the fourth reference line segment RL4 described below are successively farther from the starting point of the first reference line segment RL1 in the width direction Z. In some embodiments, a length of the first reference line segment RL1 may be in a range of 13 mm-20 mm. If the length of the first reference line segment RL1 is too small, the free end FE may be unable to extend into the cavity of auricular concha, and the sound outlet hole 111a disposed on the core module 11 is too far away from the external ear canal. If the length of the first reference line segment RL1 is too large, it is also easy to cause the free end FE to be unable to extend into the cavity of auricular concha, and the external ear canal may be blocked by the core module 11. In other words, such configuration may allow the free end FE to extend into the cavity of auricular concha, while realizing that the sound outlet hole 111a disposed on the core module 11 has a suitable distance from the external ear canal, such that the user can receiving more sound waves generated by the core module 11 without blocking the external ear canal.
In some embodiments, the second reference line segment RL2 passing through ¼ of the first reference line segment RL1 and parallel to the length direction Y may intersect the first segment S1 and the second segment S2 at a first intersection point P1 and a second intersection point P2, respectively. A distance between the first intersection point P1 and the starting point of the first reference line segment RL1 may be in a range of 9 mm-15 mm, and a distance between the second intersection point P2 and the starting point of the first reference line segment RL1 may be in a range of 12 mm-19 mm. The third reference line segment RL3 passing through ½ of the first reference line segment RL1 and parallel to the length direction Y may intersect the first segment S1 and the second segment S2 at a third intersection point P3 and a fourth intersection point P4, respectively. A distance between the third intersection point P3 and the starting point of the first reference line segment RL1 may be in a range of 11 mm-18 mm, and a distance between the fourth intersection point P4 and the starting point of the first reference line segment RL1 may be in a range of 12 mm-19 mm. The fourth reference line segment RL4 passing through ¾ of the first reference line segment RL1 and parallel to the length direction Y may intersect the first segment S1 and the second segment S2 at a fifth intersection point P5 and a sixth intersection point P6, respectively. A distance between the fifth intersection point P5 and the starting point of the first reference line segment RL1 may be in a range of 12 mm-19 mm, and a distance between the sixth intersection point P6 and the starting point of the first reference line segment RL1 may be in a range of 12 mm-19 mm. In this way, when the free end FE extends into the cavity of auricular concha and the sound outlet 111a disposed on the core module 11 has a suitable distance from the external ear canal, the hook structure 12 can better fit the ear.
In some embodiments, the fifth reference line segment RL5 with the shortest spacing along the length direction Y may be disposed between the second section S2 and the rear side surface RS, and a length of the fifth reference line segment RL5 may be in a range of 2 mm-3 mm. If the length of the fifth reference line segment RL5 is too small, the clamping force of the core module 11 and the hook structure 12 on the ear may be too large, which may cause wearing discomfort; and if the length of the fifth reference line segment RL5 is too large, the clamping force of the core module 11 and the hook structure 12 on the ear may be too small, which may cause wearing instability. In other words, such configuration realizes both the stability and comfort of the earphone 10 in the wearing state.
In some embodiments, a point where the fifth reference line segment RL5 intersects with the rear side surface RS may be regarded as a starting point of the fifth reference line segment RL5, and a point where the fifth reference line segment RL5 intersects with the second section S2 may be regarded as an end point of the fifth reference line segment RL5. An orthographic projection of an intersection point of the first reference line segment RL1 and the upper side surface US along the length direction Y may intersect with the second section S2 at a seventh intersection point P7. An orthographic projection of an intersection point of an extension line of the first reference line segment RL1 and the lower side surface LS along the length direction Y may intersect with the second section S2 at an eighth intersection point P8. A distance between the seventh intersection point P7 and the starting point of the fifth reference line segment RL5 may be in a range of 5 mm-9 mm, and a distance between the eighth intersection point P8 and the starting point of the fifth reference line segment RL5 may be in a range of 5 mm-9 mm. In this way, the hook structure 12 can better fit the ear while realizing both the stability and comfort of the earphone 10 in the wearing state.

In some embodiments, the earphone 10 may include an adjustment mechanism configured to connect the core module 11 and the hook structure 12. Different users may adjust a relative position of the core module 11 on the ear through the adjustment mechanism in the wearing state, such that the core module 11 may be located at a suitable position, and the core module 11 and the cavity of auricular concha may form the auxiliary cavity. In addition, due to the adjustment mechanism, the user may also adjust the earphone 10 to a more stable and comfortable position.

For example, the flexible insert 1131 may be continuously disposed on at least a portion of the core housing 111 corresponding to the rear side surface RS, the upper side surface US, and the lower side surface LS. For example, a region of the core housing 111 corresponding to the rear side surface RS may be covered by the flexible insert 1131 by more than 90%, and a region of the core housing 111 corresponding to the upper side surface US and the lower side surface LS may be covered by the flexible insert 1131 by about 30%. In this way, the comfort of the earphone 10 in the wearing state and the need to set structural parts such as the loudspeaker 112 in the core housing 111 may both be realized.
In some embodiments, when viewed along the thickness direction X, the flexible insert 1131 may be arranged in a U-shape.
In some embodiments, the portion of the flexible insert 1131 corresponding to the lower side surface LS may abut against an antitragus. A thickness of a portion of the flexible insert 1131 corresponding to the rear side surface RS may be respectively less than a thickness of a portion of the flexible insert 1131 corresponding to the upper side surface US and a thickness of a portion of the flexible insert 1131 corresponding to the lower side surface LS, such that good comfort can be obtained when the core module 11 abuts against an uneven position in the cavity of auricular concha.

In some embodiments, the antenna pattern 1141 may be configured to surround the periphery of the touch control pattern 1142 to fully utilize the space of the outer side of the core outer housing 1112. The antenna pattern 1141 may be arranged in a U-shape, and the touch control pattern 1142 may be arranged in a square shape.
In some embodiments, the core module 11 may include a microphone 133 welded on the main control circuit board 13. The microphone 133 may be configured to pick up a user voice and an ambient sound through a sound pickup through hole provided on the core outer housing 1112. When the main control circuit board 13 is connected with the core outer housing 1112, the microphone 133 may be pressed on the core outer housing 1112.

In some embodiments, the second side wall 1116 may include a first sub-side wall segment 1117 and a second sub-side wall segment 1118 connected with the first sub-side wall segment 1117. The first sub-side wall segment 1117 may be closer to the top wall 1115 than the second sub-side wall segment 1118 in the thickness direction X, and the second sub-side wall segment 1118 may protrude toward the outer side of the core housing 111 compared to the first sub-side wall segment 1117. In short, the second side wall 1116 may have a stepped structure. In this way, the flexible insert 1131 may be accumulated on the core outer housing 1112 during the injection molding process to avoid overflowing of the flexible insert 1131, the core module 11 may better abut against the cavity of auricular concha through the flexible insert 1131, thereby improving the comfort of the earphone 10 in the wearing state.
In some embodiments, the main control circuit board 13 may be connected with the core outer housing 1112 (e.g., fixed on a hot melt column connected with the top wall 1115), and may partially overlap with the first sub-side wall section 1117 in the thickness direction X. The loudspeaker 112 may partially overlap with the second sub-side wall section 1118 in the thickness direction X. In this way, a sufficiently large loudspeaker 112 may be disposed in the core housing 111, thereby enhancing the sound volume produced by the earphone 10.
In some embodiments, referring to
In some embodiments, the core housing 111 may be provided with a sound adjustment hole 111d. The sound adjustment hole 111d may make the resonance frequency of the second sound leakage shift to a higher frequency band (e.g., a frequency range greater than 4 kHz) as much as possible, thereby further preventing the second leakage sound from being heard. An area of the sound adjustment hole 111d may be less than an area of the pressure relief hole 111c, such that the space on the side of the loudspeaker 112 toward the main control circuit board 13 may be more communicated with the external environment through the pressure relief hole 111c. In some embodiments, a spacing between the sound outlet hole 111a and the pressure relief hole 111c in the width direction Z may be greater than a spacing between the sound outlet hole 111a and the sound adjustment hole 111d in the width direction Z, so as to prevent the sound wave propagated through the sound outlet hole 111a and the pressure relief hole 111c respectively from canceling each other in opposite phases in a near field, thereby increasing the volume of the sound propagated through the sound outlet hole 111a heard by the user. Accordingly, the sound adjustment hole 111d may be closer to the connection end CE than the sound outlet hole 111a to increase the spacing between the sound adjustment hole 111d and the sound outlet hole 111a in the length direction Y, thereby preventing the sound wave propagated through the sound outlet hole 111a and the sound adjustment hole 111c respectively from canceling each other in opposite phases in the near field, and increasing the volume of the sound propagated through the sound outlet hole 111a heard by the user.

In some embodiments, the support 115 may cooperate with the core housing 111 to form a first gluing groove 1171 surrounding at least a portion of the acoustic hole. The first gluing groove 1171 may be configured to accommodate a first glue for sealing an assembly gap between the support 115 and the core housing 111, i.e., waterproof sealing may be performed through the first glue, which prevents sweat, rainwater, and other liquid droplets from the outside from invading the space where the main control circuit board 13 is located in the core housing 111. In this way, based on the Helmholtz resonator, compared with the related art that a silicone sleeve is pressed on the core housing 111 by the support 115 for waterproof sealing, the present disclosure performs waterproof sealing by the first glue, which can save the silicone sleeve in the related art, and shorten a length of a portion (including the acoustic channel 1151 and the acoustic hole) of the acoustic cavity 116 communicated with the external environment, such that the resonance frequency of the leakage sound (i.e., the second leakage sound) formed by propagating through the pressure relief hole 111c is shifted to a higher frequency band (e.g., a frequency range greater than 4 kHz) as much as possible, thereby further preventing the second leakage sound from being heard.
It should be noted that when the acoustic hole is a pressure relief hole 111c, the first gluing groove 1171 may surround at least a portion of the pressure relief hole 111c; when the acoustic hole is the sound adjustment hole 111d, the first gluing groove 1171 may surround at least a portion of the sound adjustment hole 111d; when the acoustic holes are the pressure relief hole 111c and the sound adjustment hole 111d, the first gluing groove 1171 may surround at least a portion of the pressure relief hole 111c and the sound adjustment hole 111d, respectively.

In some embodiments, the annular carrier 1122 may include a first annular platform 1123 and a second annular platform 1124 which are arranged in a stepped shape. The second annular platform 1124 may be arranged around a periphery of the first annular platform 1123. A portion of the lower end of the support 115 may be supported on the first annular platform 1123, and another portion of the lower end of the support 115 may form a spacing region with the second annular platform 1124, such that the support 115, the annular carrier 1122, and the core housing 111 may cooperate to form a second gluing groove 1172. The second gluing groove 1172 may be configured to accommodate a second glue for sealing an assembly gap between any two of the support 115, the annular carrier 1122, and the core housing 111 to realize waterproof sealing.
In some embodiments, an upper end of the support 115 may be placed on the body 1121 and cooperate with the body 1121 to form a third gluing groove 1173. The third gluing groove 1173 may be configured to accommodate a third glue for sealing an assembly gap between the support 115 and the body 1121 to realize waterproof sealing.
It should be noted that the specific assembly process of the core module 11 may include following process operations, and the order of all process operations may be adjusted as needed. The process operations include: 1) pre-fixing the acoustic resistance mesh 118 at the bottom of the concave region 1119 by the double-sided tape; 2) fixing the loudspeaker 112 on the bottom wall 1113, and dispensing the glue to an assembly gap between the loudspeaker 112 and the bottom wall 1113, the glue partially being accumulated on the second annular platform 1124 of the loudspeaker 112; 3) before the glue in the operation 2) is cured, fixing the support 115 on the loudspeaker 112, wherein the lower end of the support 115 is supported on the first annular platform 1123 of the loudspeaker 112, so that a space between the lower end of the support 115 and the second annular platform 1124 is be filled with the glue, the docking portion 1153 of the support 115 pressing the acoustic resistance mesh 118 and cooperating with the first side wall 1114 to form the first gluing groove 1171, and the upper end of the support 115 being placed on the body 1121 and cooperating with the body 1121 to form the third gluing groove 1173; and 4) dispensing the glue to the first gluing groove 1171, the third gluing groove 1173, and the assembly gaps between the lower end of the support 115 and the loudspeaker 112 and the core inner housing 1111. Since the assembly gaps between the lower end of the support 115 and the loudspeaker 112 and the core inner housing 1111 are very close to the first gluing groove 1171, the assembly gaps between the lower end of the support 115 and the loudspeaker 112 and the core inner housing 1111 may be simply regarded as a continuation of the first gluing groove 1171, i.e., the first gluing groove 1171 and the second gluing groove 1172 may be communicated.

It should be noted that the adapter housing 122 forming the accommodation cavity 124 in advance means that the accommodation cavity 124 may formed at the same time when the adapter housing 122 is molded, rather than being formed after the adapter housing 122 is molded. For example, the adapter housing 122 may be a plastic housing, and the corresponding accommodation cavity 124 may be obtained after the plastic housing is injection-molded by setting a corresponding core. Correspondingly, the electronic component 15 being mounted the accommodation cavity 124 subsequently refers to that the electronic component 15 and the adapter housing 122 are non-integrally molded structural parts. For example, the adapter housing 122 may be a plastic housing, and the electronic component 15 may not be integrally injection-molded in the plastic housing by means of an insert. Accordingly, the description of the adapter housing 122 forming a through hole 1251, a blind hole 1252, and a through hole 1253 in advance mentioned in the following is the same or similar, which is not repeated here. In some embodiments, the accommodation cavity 124 may also be obtained by a drilling process after the adapter housing 122 is formed, and the through hole 1251, the blind hole 1252, and the through hole 1253 may also be obtained by the drilling process after the adapter housing 122 is formed.

In some embodiments, the one or more electrode terminals 151 may include a positive charging terminal 1511 and a negative charging terminal 1512 which are spaced apart from each other. The positive charging terminal 1511 and the negative charging terminal 1512 may be disposed in respective through holes 1251, respectively, such that the earphone 10 may be charged through the one or more electrode terminals 151. In some embodiments, only one of the positive charging terminal 1511 and the negative charging terminal 1512 may be disposed on the adapter housing 122, and the other of the positive charging terminal 1511 and the negative charging terminal 1512 may be disposed on another housing in the hook structure 12 (e.g., the battery housing 123), or on the core inner housing 1111.
In some embodiments, the one or more electrode terminals 151 may include a detection terminal 1513 spaced apart from the positive charging terminal 1511 and the negative charging terminal 1512. The detection terminal 1513 may be configured to perform detection functions such as charging detection, detection of the earphone 10 being placed in or taken out of a charging case, etc. In some embodiments, the detection terminal 1513 may also be replaced with an electronic component such as a Hall sensor.
In some embodiments, when viewed along the extension direction of the electrode terminals 151, connection lines between every two of the positive charging terminal 1511, the negative charging terminal 1512, and the detection terminal 1513 may form a triangle, such as an equilateral triangle.
In some embodiments, when viewed along the extension direction of the electrode terminals 151, the positive charging terminal 1511, the negative charging terminal 1512, and the detection terminal 1513 may be spaced apart from each other in a line segment, such as in a straight line segment. A spacing between the positive charging terminal 1511 and the negative charging terminal 1512 may be greater than a spacing between the negative charging terminal 1512 and the detection terminal 1513. For example, the negative charging terminal 1512 may be located between the positive charging terminal 1511 and the detection terminal 1513, and the spacing between the positive charging terminal 1511 and the negative charging terminal 1512 may be greater than the spacing between the negative charging terminal 1512 and the detection terminal 1513. As another example, the detection terminal 1513 may be located between the positive charging terminal 1511 and the negative charging terminal 1512. In this way, when the space for setting the electrode terminals 151 on the adapter housing 122 is limited, the spacing between the positive charging terminal 1511 and the negative charging terminal 1512 may be increased as much as possible, thereby avoiding a short circuit between the positive charging terminal 1511 and the negative charging terminal 1512.

In some embodiments, the hook structure 12 may include a flexible coating 128. The hardness of the flexible coating 128 may be less than the hardness of the adapter housing 122. The adapter housing 122 may be a plastic part. A material of the flexible coating 128 may be silicone, rubber, etc., and the flexible coating 128 may be provided on the adapter housing 122 by injection molding, glue connection, etc. In some embodiments, the flexible coating 128 may cover the adapter housing 122 and the magnet 127, such that the magnet 127 is not exposed and the electrode terminals 151 are exposed, i.e., the magnet 127 is invisible and the electrode terminals 151 are visible. In this way, the use requirements of the electrode terminals 151 can be met, and the magnet 127 can be shielded to prevent the magnet 127 from being exposed and worn or affecting the appearance quality. In addition, the flexible coating 128 may also be conducive to improving the comfort of the earphone 10 in the wearing state. The thickness of the flexible coating 128 may be less than the thickness of the adapter housing 122.

In some embodiments, the adapter housing 122 may include two housings of which parting surfaces are perpendicular to the extension direction of the electrode terminals 151. The two housings may be buckled together to form the accommodation cavity 124. The support assembly 17 may be integrally formed with one of the two housings to respectively support (or press) the electrode terminals 151 and the microphone 152 when the two housings are buckled. Alternatively, in the support assembly 17, at least one of a first support member for supporting the electrode terminals 151 and a second support member for supporting the microphone 152 may be independent of the adapter housing 122 to respectively support (or press) the electrode terminals 151 and the microphone 152 when the two housings are buckled, or the support assembly 17 may be assembled after the two housings are buckled to respectively support (or press) the electrode terminals 151 and the microphone 152.
In some embodiments, at least a portion of the adapter housing 122 corresponding to the accommodation cavity 124 may be a complete housing structure. In the support assembly 17, at least one of the first support member for supporting the electrode terminals 151 and the second support member for supporting the microphone 152 may be independent of the adapter housing 122 to at least facilitate the assembly of the electrode terminals 151.

In some embodiments, in the support assembly 17, the first support member for supporting the electrode terminals 151 and the second support member for supporting the microphone 152 may be independent of the adapter housing 122, respectively, i.e., the first support member and the second support member may be independent of each other to respectively support (or press) the electrode terminals 151 and the microphone 152. In this way, the first support member and the second support member of the support assembly 17 may be set differently according to actual needs.
In some embodiments, the support assembly 17 may be an integrally formed structural member, i.e., in the support assembly 17, the first support member for supporting the electrode terminals 151 and the second support member for supporting the microphone 152 may be connected with each other, which simplifies the structure of the support assembly 17, and avoids the first support member and the second support member being too small to assemble. The support assembly 17 may be tightly fixed with a cavity wall of the accommodation cavity 124 after being inserted in place, i.e., the support assembly 17 may have a certain damping during an insertion or removal process, and the structure is simple and reliable. Correspondingly, the cavity wall of the accommodation cavity 124 may be provided with a guide groove and a limiting groove which cooperate with the support assembly 17. In some embodiments, the support assembly 17 may be connected with the cavity wall of the accommodation cavity 124 through a glue dispensing process.

In some embodiments, an orthographic projection of the microphone 152 on the first cavity wall 1241 may cover at least a portion of the electrode terminals 151 (e.g., the microphone 152 may cover a portion of the positive charging terminal 1511), which makes the structure of each portion more compact.
In some embodiments, a size of at least a portion of the bottom plate 171 and the size of at least a portion of the accommodation cavity 124 in a first reference direction RD1 perpendicular to the insertion direction and parallel to the one side main surface of the bottom plate 171 may be set to gradually decrease along the insertion direction, i.e., one of a front end and a rear end of the bottom plate 171 in the insertion direction or a local portion between the front end and the rear end may be set to maintain the size in the first reference direction RD1 constant along the insertion direction. A size of the first side plate 172 and a size of the accommodation cavity 124 in a second reference direction RD2 perpendicular to the insertion direction and parallel to the one side main surface of the first side plate 172 may be set to maintain constant along the insertion direction.
In some embodiments, a size of at least a portion of the first side plate 172 and the size of at least a portion of the accommodation cavity 124 in the second reference direction RD2 perpendicular to the insertion direction and parallel to the one side main surface of the first side plate 172 may be set to gradually decrease along the insertion direction, i.e., one of a front end and a rear end of the first side plate 172 in the insertion direction or a location portion between the front end and the rear end may be set to maintain the size in the second reference direction RD2 constant along the insertion direction. The size of the bottom plate 171 and the size of accommodation cavity 124 in the first reference direction RD1 perpendicular to the insertion direction and parallel to the one side main surface of the bottom plate 171 may be set to maintain constant along the insertion direction.
In some embodiments, a size of at least a portion of the first side plate 172 and the size of at least a portion of the accommodation cavity 124 in the second reference direction RD2 perpendicular to the insertion direction and parallel to the one side main surface of the first side plate 172 may be set to gradually decrease along the insertion direction, and the size of at least a portion of the first side plate 172 and the size of at least a portion of the accommodation cavity 124 in the second reference direction RD2 perpendicular to the insertion direction and parallel to the one side main surface of the first side plate 172 may be set to gradually decrease along the insertion direction.
It should be noted that for the support assembly 17, the size of the bottom plate 171 in the first reference direction RD1 may be simply regarded as a width of the bottom plate 171, and the size of the first side plate 172 in the second reference direction RD2 may be simply regarded as a height of the first side plate 172.

In some embodiments, compared with the bottom plate 171, a height of the second side plate 173 may be greater than a height of the first side plate 172 and a height of the third side plate 174, such that the second side plate 173 may abut against the second cavity wall 1242, and the third side plate 174 may abut against the fourth cavity wall 1244. Since the second side plate 173 and the third side plate 174 do not directly contact any one of the electrode terminals 151 and the microphone 152, the second side plate 173 and the third side plate 174 may be configured for guidance during the insertion of the support assembly 17 into the accommodation cavity 124. Accordingly, since the height of the second side plate 173 is the highest relatively, the support assembly 17 may include a reinforcing rib 175 configured to connect the second side plate 173 and the bottom plate 171. The reinforcing rib 175 may be provided on opposite sides of the second side plate 173 toward the first side plate 172 and the third side plate 174.

In some embodiments, the flexible coating 128 may cover at least an exposed portion of the elastic metal wire 121 and the lead 129, and at least a portion of the battery 123, such that the lead 129 may be exposed, thereby improving the appearance quality of the earphone 10.
It should be noted that the adapter housing 122 may also be regarded as a portion of the structure of the core housing 111. For example, the adapter housing 122 may be integrally formed with the core inner housing 1111. As another example, a portion of the adapter housing 122 may be integrally formed with the core inner housing 1111 and a rest portion of the adapter housing 122 may be integrally formed with the core outer housing 1112. Other portions of the hook structure 12 except the adapter housing 122, such as the end of the elastic metal wire 121 away from the battery housing 123 and the battery housing 123, may be fixedly connected with the core module 11 with the adapter housing 122 at the adapter housing 122 (e.g., through plugged fixation). Correspondingly, structural components such as the electrode terminals 151, the microphone 152, and the magnet 127 may be also adjusted in position accordingly, which is not repeated here.
According to the above related description, the present disclosure provides a housing assembly. The housing assembly may include a plastic housing, a metal functional pattern, and a silicone coating. The metal functional pattern may be disposed on an outer side of the plastic housing. The silicone coating may be disposed on a side of the metal functional pattern away from the plastic housing and on the plastic housing not covered by the metal functional pattern through integral injection molding, glue connection, etc. Accordingly, compared with the metal functional pattern being disposed on an inner side of the plastic housing away from the silicone coating, the metal functional pattern may be disposed on the outer side of the plastic housing toward the silicone coating, such that the metal functional pattern may be further away from the interference of other electronic components of the housing assembly, or closer to a signal trigger source outside the housing assembly, thereby increasing the anti-interference performance and sensitivity of the metal functional pattern. The structure of the plastic housing may be the same or similar to that of the core housing 111 or the core outer housing 1112, and the structure of the silicone coating may be the same or similar to that of the flexible coating 1132, which is not repeated here.
In some embodiments, the metal functional pattern may be configured as the antenna pattern 1141 or the touch control pattern 1142. The antenna pattern 1141 may be disposed on the outer side of the plastic housing, which may increase a spacing between the antenna pattern 1141 and other electronic components of the plastic housing, i.e., increase an antenna clearance region, thereby increasing the anti-interference performance of the antenna pattern 1141. The touch control pattern 1142 may be disposed on the outer side of the plastic housing, which may shorten a spacing between the touch control pattern 1142 and an external signal trigger source (e.g., a user's finger), i.e., shorten a touch spacing, thereby increasing the sensitivity of the touch control pattern 1142 to be triggered by the user.
In some embodiments, the metal functional pattern may include the antenna pattern 1141 and the touch control pattern 1142. The antenna pattern 1141 may surround a periphery of the touch control pattern 1142 to fully utilize the space of the outer side of the plastic housing. The antenna pattern 1141 may be set in a U shape, and the touch control pattern 1142 may be set in a square shape.
In some embodiments, a thickness of the silicone coating may be less than a thickness of the plastic housing, such that the silicone coating may shield and protect the metal functional pattern while further increasing the anti-interference performance and sensitivity of the metal functional pattern and reducing the volume of the housing assembly.
In some embodiments, the housing assembly may be regarded as a core housing for accommodating the loudspeaker 112. A relative positional relationship between the plastic housing and the plastic coating may be the same or similar to that between the core housing 111 and the flexible coating 1132, which is not repeated here.
In some embodiments, in addition to being applied to the earphone 10, the housing assembly may also be applied to other electronic devices such as smart glasses. The electronic device may include a core module provided with the loudspeaker 112, and may also include the main control circuit board 13, and the loudspeaker 112 and the battery 14 are respectively coupled with the main control circuit board 13. The housing assembly may be configured to accommodate at least one of the electronic components such as the loudspeaker 112, the main control circuit board 13, and the battery 14, and may also be configured to support the loudspeaker 112 of the electronic device to be located in a corresponding wearing position. It should be noted that for electronic devices such as an earphone and the smart glasses based on the bone conduction principle, the loudspeaker 112 may be adaptively adjusted to a bone conduction loudspeaker. The basic structure of the bone conduction loudspeaker is well known to those skilled in the art, which is not repeated here.
The present disclosure provides a housing assembly. The housing assembly may include a first housing, the one or more electrode terminals 151, the magnet 127, and the flexible coating 128. The electrode terminals 151 and the magnet 127 may be exposed on the same side of the first housing. The hardness of the flexible coating 128 may be less than that of the first housing, and the flexible coating 128 may be disposed on the first housing and the magnet 127, such that the magnet 127 may not exposed and the electrode terminals 151 may be exposed. In this way, compared with the magnet 127 being disposed in the first housing, the present disclosure makes the magnet 127 closer to the outside region to which an exposed end of the electrode terminals 151 faces, thereby shortening a spacing between the magnet 127 and a magnetic suction structure used to cooperate with the magnet 127 in a charging device such as a charging case or a spacing between the magnet 127 and a Hall sensor configured to cooperate with the magnet 127, thereby improving the reliability of functions such as charging and detection. Therefore, the housing assembly may be applied to both power receiving devices (e.g., the earphone 10 and the smart glasses) and the charging device (e.g. the charging case). In other words, the electronic device may be the power receiving device or the charging device. For the ease of description, the first housing may be the adapter housing 122.
In some embodiments, the first housing may be provided with the one or more through holes 1251 and the blind hole 1252. The electrode terminals 151 may be at least partially disposed in the one or more through holes 1251. The magnet 127 may be at least partially disposed in the blind hole 1252 and exposed through an open end of the blind hole 1252. In this way, the thickness of the first housing in a region where the magnet 127 is located can be reduced, the appearance quality of the first housing in the region where the magnet 127 is located can be improved. In some embodiments, the blind hole 1252 may also be configured as a through hole.
In some embodiments, the boss 126 may be provided on an outer side of the first housing. The boss 126 may be provided adjacent to the magnet 127 and protrude from the first housing around the magnet 127. The through holes 1251 may penetrate through the boss 126, such that a plurality of electrode terminals 151 may be exposed out the boss 126. In this way, the boss 126 may make an uneven portion of the first housing with a certain curvature become flat, so as to facilitate the arrangement of the electrode terminals 151. The boss 126 may be provided in a long strip shape, which is simple and reliable in structure.
In some embodiments, the housing assembly may include the flexible circuit board 16. The electrode terminals 151 may be connected with the flexible circuit board 16 to simplify the wiring of the electrode terminals 151. The first housing may form the accommodation cavity 124. At least a portion of the flexible circuit board 16 may be disposed in the accommodation cavity 124. The through holes 1251 may be communicated with the accommodation cavity 124, and the blind hole 1252 may not be communicated with the accommodation cavity 124, so as to improve the waterproof and dustproof performance of the first housing.
In some embodiments, the housing assembly may include a second housing, the elastic metal wire 121, and the lead 129. Two ends of the elastic metal wire 121 and two ends of the lead 129 may be connected with the first housing and the second housing, respectively, such that the lead 129 may extend along the elastic metal wire 121 and may be inserted into the first housing and the second housing. For ease of description, the second housing may be the battery housing 123. In some embodiments, the battery 14 may be disposed in the second housing. The battery 14 may be connected with the flexible circuit board 16 through the lead 129, i.e., the battery 14 and the electrode terminals 151 may both be connected with the flexible circuit board 16 to simplify the wiring. Accordingly, the flexible coating 128 may be at least disposed on the elastic metal wire 121 and the lead 129, such that the lead 129 may be exposed.
In some embodiments, the housing assembly may be configured for the earphone 10 and may include a third housing for accommodating the loudspeaker 112. The third housing may be plugged with the first housing for fixation. For ease of description, the third housing may be the core housing 111.
The present disclosure provides a housing assembly. The housing assembly may include a first housing, the one or more electrode terminals 151, the microphone 152, and the support assembly 17. The first housing may be provided with the accommodation cavity 124, and the through holes 1251 and the through holes 1253 are respectively connected with the accommodation cavity 124. The through holes 1251 and the through holes 1253 may be located on different side walls of the first housing. The one or more electrode terminals 151 may be at least partially disposed in the through holes 1251. The microphone 152 may be disposed in the accommodation cavity 124, and pick up a sound outside the housing assembly through the through holes 1253. In some embodiments, the support assembly 17 may be disposed in the accommodation cavity 124, and may support and fix the electrode terminals 151 and the microphone 152 on the side walls corresponding to the through holes 1251 and the through holes 1253, respectively. In this way, the electrode terminals 151 and the microphone 152 can be prevented from being separated from the first housing, the waterproof and dustproof performance at the electrode terminals 151 and the microphone 152 can be improved, and the structure is simple and reliable. For the ease of description, the first housing may be the adapter housing 122, the core housing 111, or a housing structure in which the core housing 111 and the adapter housing 122 are integrally formed.
In some embodiments, the support assembly 17 may be independent of the first housing and inserted into the accommodation cavity 124.
In some embodiments, the support assembly 17 may be an integrally formed structure.
In some embodiments, the housing assembly may be configured for the earphone 10 and may include a third housing for accommodating the loudspeaker 112. The third housing may be plugged with the first housing for fixation. The first housing may be the adapter housing 122, and the third housing may be the core housing 111.
In some embodiments, in addition to being applied to the earphone 10, the housing assembly may also be applied to other electronic devices such as smart glasses. The electronic device may include the main control circuit board 13, and the loudspeaker 112 and the battery 14 are respectively coupled with the main control circuit board 13.

In some embodiments, the inner side surface IS may be configured as a plane. In the non-wearing state, a plane where the inner side surface IS is located may intersect with the hook structure 12.
In some embodiments, in the wearing state, a clamping force applied by the hook structure 12 and the core module 11 on the ear in the thickness direction X (e.g., the earphone 10 may clamp the ear from left and right directions of the head) may be regarded as a portion of the clamping force of the earphone 10 on the ear. The clamping force may be measured with a dynamometer. For example, the earphone 10 may be worn on the simulator or the ear of the user, i.e., be in the wearing state; then the dynamometer (e.g., a Wedo WDF-10 digital push-pull dynamometer, which is not repeated below) is fixed on a side of the core module 11 away from the ear, then the dynamometer may be pulled and viewed; when the side of the core module 11 toward the ear of the user is just separated from the skin of the ear, a tension force displayed on the dynamometer may be obtained, and the tension force may be simply regarded as the clamping force.

In some embodiments, a diameter of the elastic metal wire 121 may be in a range of 0.6 mm-0.8 mm. If the diameter is too small, the elastic metal wire 121 may provide an insufficient clamping force and insufficient structural strength. If the diameter is too large, the elastic metal wire 121 may be difficult to deform elastically and may provide an excessive clamping force.

In some embodiments, the first intersection point O1 and the second intersection point O2 may be connected to form a first reference line segment O1O2. The first reference line segment O1O2 may have a first component and a second component in the length direction Y and the thickness direction Z, respectively. A ratio of the length of the first component to the length of the core module 11 in the length direction Y may be in a range of 0.12 and 0.19, a ratio of the thickness of the second component to the thickness of the core module 11 in the thickness direction X may be in a range of 0.1-0.16. In this way, the hook structure 12 may be allowed to have a suitable angle (e.g., an angle θ in a range of) 15°-30° with the inner side surface IS, thereby allowing the earphone 10 to apply a suitable clamping force to the ear.
In some embodiments, a farthest point O3 of the median line ML in the thickness direction X which is farthest from the inner side surface IS may be connected with the first intersection point O1 to form a second reference line segment O1O3. The second reference line segment O1O3 may have a third component and a fourth component in the length direction Y and the thickness direction X, respectively. A ratio of the length of the third component to the length of the core module 11 in the length direction Y may be in a range of 0.43-0.66, and a ratio of the thickness of the fourth component to the thickness of the core module 11 in the thickness direction X may be in a range of 0.26-0.4. In this way, the hook structure 12 may be allowed to have a suitable angle (e.g., an angle θ in a range of) 15°-30° with the inner side surface IS, thereby allowing the earphone 10 to apply a suitable clamping force to the ear.
In some embodiments, referring to
In some embodiments, in the wearing state, a clamping force applied to the ear by the hook structure 12 and the core module 11 in a direction perpendicular to the thickness direction X (e.g., the earphone 10 may clamp the ear from front and rear directions of the head) may be regarded as a portion of the clamping force of the earphone 10 on the ear. The clamping force may be measured with a dynamometer. For example, the earphone 10 may be worn on the simulator or the ear of the user, i.e., in the wearing state; the dynamometer may be fixed to the end of the hook structure 12 that is away from the core module 11, and the dynamometer may be pulled and viewed; when a side of the hook structure 12 toward the ear of the user is just separated from the skin of the ear, a tension force displayed on the dynamometer may be obtained, and the tension force may be regarded as the clamping force.
In some embodiments, in the non-wearing state, the deformation capability of the hook structure 12 relative to the core module 11 may be reflected by a corresponding measurement mode, thereby characterizing the clamping force that the earphone 10 may apply on the ear. The measurement mode is exemplarily described below.
In some embodiments, referring to
In some embodiments, after the core module 11 is fixed, the hook structure 12 may have a tension force in a range of 0.1 N-1.96 N after being pulled apart by a distance in a range of 1 mm-5 mm with respect to the core module 11 at the measurement fixed position P1 in the direction that is parallel to the first reference line segment RL1 and away from the core module 11.
In some embodiments, in a non-wearing state, the earphone 10 may be fixed on a measurement platform. For example, the core module 11 may be fixed on a fixture of the measurement platform. In this case, the first reference line segment RL1 may be parallel to a horizontal plane, and the hook structure 12 may be in a suspended state. Accordingly, a dynamometer 20 may be fixed on the hook structure 12. For example, a hook of the dynamometer 20 may be hooked or sleeved on the measurement fixed position P1, and the measurement fixed position P1 may be shown as a straight line segment in
In some embodiments, in the non-wearing state, the core module 11 may be pressed on an edge of a table, and the hook structure 12 may be maintained suspended as much as possible. Similarly, the hook of the dynamometer 20 may be hooked or sleeved on the measurement fixed position P1, and the measurement may be performed as described above, which is not repeated here.
The following table gives an exemplary description of a corresponding relationship between the tension force F and the distance d at different measurement fixed positions P1. The unit of the tension force F is denoted as N, and the unit of the distance d is denoted as mm. Further, in the following table, #1, #2, and #3 respectively represent the measurement fixed positions P1, which are 16 mm, 21.5 mm, and 27 mm away from the free end of the hook structure 12 that is not connected with the core module 11 in the length direction of the hook structure 12, respectively. It should be noted that in order to reduce the measurement error, each tension force F may be averaged after multiple measurements. For example, the average value may be taken after three measurements.
In some embodiments, a length of the first reference line segment RL1 may be in a range of 2 mm-3 mm. If the length of the first reference line segment RL1 is too small, the earphone 10 may be uncomfortable to wear; and if the length of the first reference line segment RL1 is too large, the earphone 10 may be unstable to wear. In some embodiments, a spacing between the measurement fixed position P1 and the first reference line segment RL1 may be less than or equal to 1 mm, so as to allow the measurement fixed position P1 to be as close as possible to a preset position of the hook structure 12 that contacts the ear.
In some embodiments, the core module 11 may have the length direction Y and the width direction Z that are perpendicular to the thickness direction X and orthogonal to each other. The length of the core module 11 in the length direction Y may be greater than the width of the core module 11 in the width direction Z. In some embodiments, referring to
In some embodiments, referring to
In some embodiments, a direction of the first reference line segment RL1 may be parallel to the length direction Y. In other words, when an orthographic projection of the core module 11 on a reference plane perpendicular to the thickness direction X is set to a rounded rectangle, a spacing between the orthographic projection of the hook structure 12 and the orthographic projection of the core module 11 in the length direction Y may be minimum.
In some embodiments, a point P3 where the second reference line segment RL2 intersects with the orthographic projection of the core module 11 may be regarded as a starting point of the second reference line segment RL2, and a point P4 where the second reference line segment RL2 intersects with the orthographic projection of the hook structure 12 may be regarded as an end point of the second reference line segment RL2. The third reference line segment RL3 passing through ¼ of the second reference line segment RL2 and parallel to the length direction Y may intersect with the hook structure 12 at a first intersection point P5 and a second intersection point P6. The first intersection point P5 may be closer to the core module 11 than the second intersection point P6 in the length direction of the hook structure 12. In some embodiments, a distance between the first intersection point P5 and the starting point of the second reference line segment RL2 may be in a range of 9 mm-15 mm, and a distance between the second intersection point P6 and the starting point of the second reference line segment RL2 may be in a range of 12 mm-19 mm. With such configuration, when the free end FE of the core module 11 extends into the cavity of auricular concha and the sound outlet 111a disposed on the core module 11 has a suitable distance from the external ear canal, the hook structure 12 and the core module 11 may apply a suitable clamping force on the ear.

In some embodiments, the battery housing 123 may include the cover housing 1231 connected with the elastic metal wire 121 and the battery compartment 1232 connected with the cover housing 1231. The battery compartment 1232 may cooperate with the cover housing 1231 to form a cavity structure for accommodating the battery 14. The hook structure 12 may include the flexible coating 128 that at least covers the elastic metal wire 121 and the cover housing 1231. The hardness of the flexible coating 128 may be less than a hardness of the cover housing 1231. In some embodiments, the extension line of the first reference line segment RL1 may pass through a section where the flexible coating 128 overlaps with the cover housing 1231. In this way, the hook structure 12 may further clamp the ear together with the core module 11 through the flexible coating 128 disposed on the cover housing 1231, thereby further improving the wearing comfort of the earphone 10.
In some embodiments, one end of the battery compartment 1232 in the length direction of the hook structure 12 may has an open end, and the cover housing 1231 may be partially embedded in the open end of the battery compartment 1232. An area of an outer surface of the cover housing 1231 on a reference cross-section perpendicular to the length direction of the hook structure 12 may be less than an area of an outer surface of the battery compartment 1232 on the reference cross-section perpendicular to the length direction of the hook structure 12, i.e., an outer diameter of the cover housing 1231 may be less than an outer diameter of the battery compartment 1232. In some embodiments, the flexible coating 128 may not cover the battery compartment 1232, and each of the outer surface of the flexible coating 128 and the outer surface of the battery compartment 1232 may have a smooth transition to improve the appearance quality of the earphone 10 in a non-wearing state. In this case, the measurement fixed position P1 may be located at a junction between the flexible coating 128 and the battery compartment 1232. Such configuration may allow the measurement fixed position P1 to be as close as possible to a preset position of the hook structure 12 that contacts the ear.
In some embodiments, referring to
In some embodiments, the maximum area of an outer surface of the battery housing 123 on a reference cross-section perpendicular to the length direction of the hook structure 12 may be in a range of 60 mm2-100 mm2. If the maximum area is too small, the battery housing 123 may be difficult to contact the head skin outside the ear, and the capacity of the battery 14 is insufficient to meet the endurance requirements of the earphone 10; and if the maximum area is too large, the battery housing 123 may be seen too much from the front side of the ear, which affects the appearance quality of the earphone 10 in the wearing state.
In some embodiments, referring to
In some embodiments, a contact area between the cover housing 1231 and the head skin around the ear may be less than a contact area between the battery compartment 1232 and the head skin around the ear, such that when the cover housing 1231 and the core module 11 clamp the ear, the cover housing 1231 does not need to consider the contact between the battery housing 123 and the head skin around the ear. In other words, different portions of the battery housing 123 may have different set intentions. Accordingly, the cover housing 1231 may not contact the head skin around the ear.
In some embodiments, the hook structure 12 may include the elastic metal wire 121 configured to connect the core module 11 and the cover housing 1231 and the flexible coating 128 covering at least the elastic metal wire 121 and the cover housing 1231. The cover housing 1231 may contact the ear region through the flexible coating 128 to improve the wearing comfort of the earphone 10. The flexible coating 128 may not cover the battery compartment 1232, which reduces the risk of the hook structure 12 being too thick at the battery compartment 1232 and being exposed too much from the front side of the ear, thereby improving the appearance quality of the earphone 10 in the wearing state. In some embodiments, the outer surface of the flexible coating 128 may be smoothly transitioned to the outer surface of the battery compartment 1232 to improve the appearance quality of the earphone 10 in the non-wearing state.
In some embodiments, the core module 11 may have the inner side surface IS toward the ear and the outer side surface OS away from the ear along the thickness direction X in the wearing state. The thickness direction X is defined as a direction in which the core module 11 is close to or away from the ear in the wearing state. In the non-wearing state, at least a portion of the battery housing 123 may be located between the inner side surface IS and the outer side surface OS in the thickness direction X, such that a clamping force of the earphone 10 on the ear is mainly manifested as a positive pressure, which improves the wearing comfort of the earphone 10. In some embodiments, the core module 11 may have the length direction Y and the width direction Z which are perpendicular to the thickness direction X and orthogonal to each other. The length of the core module 11 in the length direction Y may be greater than the width of the core module 11 in the width direction Z. An orthographic projection of the cover housing 1231 along the length direction Y may at least partially overlap with an orthographic projection of the core module 11 along the length direction Y, and an orthographic projection of the battery compartment 1232 along the length direction Y may at least partially not overlap with an orthographic projection of the core module 11 along the length direction Y, so as to allow the hook structure 12 to mainly clamp the ear together with the core module 11 at the cover housing 1231.
In some embodiments, referring to
In some embodiments, in the wearing state, a clamping force applied by the hook structure 12 and the core module 11 on the ear in the thickness direction X (e.g., the earphone 10 clamps the ear from left and right directions of the head) may serve as a portion of the clamping force of the earphone 10 on the ear.
In some embodiments, in the wearing state, a clamping force applied by the hook structure 12 and the core module 11 on the ear in the direction that is perpendicular to the thickness direction X (e.g., the earphone 10 clamps the ear from front and rear directions of the head) may serve as a portion of the clamping force of the earphone 10 on the ear.
In some embodiments, in a non-wearing state, the earphone 10 may have a second reference line RL2 parallel to the first reference line segment RL1 on the reference plane (e.g., the YZ plane in
In some embodiments, in the wearing state, a distance (e.g., as shown by V1 in
In some embodiments, in the wearing state, a distance (e.g., as shown by V2 in
In some embodiments, a length of the battery compartment 1232 in the length direction of the hook structure 12 may be in a range of 10 mm-20 mm. Such configuration may realize both the battery life of the earphone 10 and the appearance quality in the wearing state.
In some embodiments, the battery compartment 1232 may be provided in a hollow cylindrical shape, and an area of an outer surface of the battery compartment 1232 on a reference cross-section perpendicular to the length direction of the hook structure 12 may be in a range of 60 mm2 and 100 mm2. If the area is too small, the capacity of the battery 14 may be insufficient to meet the endurance requirements of the earphone 10; if the area is too large, the battery housing 123 may be seen too much from the front side of the ear, which affects the appearance quality of the earphone 10 in the wearing state.

In some embodiments, the orthographic projection of the transition portion 12a may have a second reference line segment RL2, a third reference line segment RL3, a fourth reference line segment RL4, and a fifth reference line segment RL5 which are parallel to the length direction Y and spaced in sequence. The second reference line segment RL2, the third reference line segment RL3, the fourth reference line segment RL4, and the fifth reference line segment RL5 may be successively farther away from the orthographic projection of the core module 11 in the width direction Z. In some embodiments, the starting point and the end point of each of the second reference line segment RL2, the third reference line segment RL3, the fourth reference line segment RL4, and the fifth reference line segment RL5 may fall on the inner edge IE and the outer edge OE, respectively. The length of the second reference line segment RL2 may be in a range of 5 mm-8 mm, and an extension line of the second reference line segment RL2 may pass through ⅛ of the first reference line segment RL1. The length of the third reference line segment RL3 may be in a range of 4 mm-6.3 mm, and an extension line of the third reference line segment RL3 may pass through ¼ of the first reference line segment RL1. The length of the fourth reference line segment RL4 may be in a range of 3.5 mm-5.4 mm, and an extension line of the fourth reference line segment RL4 may pass through ⅜ of the first reference line segment RL1. The length of the fifth reference line segment RL5 may be in a range of 3 mm-5 mm, and an extension line of the fifth reference line segment RL5 may pass through ½ of the first reference line segment RL1.
In some embodiments, the length of the first reference line segment RL1 may be in a range of 13 mm-20 mm. If the length of the first reference line segment RL1 is too small, the free end FE of the core module 11 may be unable to extend into the cavity of auricular concha, and the sound outlet hole 111a disposed on the core module 11 may be too far away from the external ear canal. If the length of the first reference line segment RL1 is too large, the free end FE may be unable to extend into the cavity of auricular concha, and the external ear canal may be excessively blocked by the core module 11. In other words, such configuration may allow the free end FE of the core module 11 to extend into the cavity of auricular concha and the sound outlet hole 111a disposed on the core module 11 may have a suitable distance from the external ear canal, such that a user can receive more sound waves generated by the core module 11 without blocking the external ear canal.
In some embodiments, the hook structure 12 may include the adapter housing 122 connected with the core module 11 and the elastic metal wire 121 connected with the adapter housing 122. At least a portion of the adapter housing 122 may be disposed on the front side of the ear in the wearing state, and at least a portion of the elastic metal wire 121 may be disposed on the rear side of the ear in the wearing state. In other words, the portion of the adapter housing 122 disposed on the front side of the ear in the wearing state may be regarded as a portion of the transition portion 12a or the entirety of the transition portion 12a. The core module 11 may have the inner side surface IS toward the ear along the thickness direction X and the outer side surface OS away from the ear in the wearing state. An area of an outer surface of the adapter housing 122 on a reference cross-section perpendicular to the length direction of the hook structure 12 may gradually decrease in a positive direction that is along the length direction of the hook structure 12 and points away from the core module 11, so as to allow the transition portion 12a to be set as a tapered structure. In some embodiments, the adapter housing 122 may extend to a side of the inner side surface IS away from the outer side surface OS in the thickness direction X, so as to allow a portion of the hook structure 12 to be staggered with a projection of the core module 11 in a direction perpendicular to the thickness direction X, and thus in the wearing state, the upper ear root of the ear may provide a less supporting force to the earphone 10. A plane where the elastic metal wire 121 is located and the inner side surface IS may intersect in a non-wearing state, so as to allow a portion of the hook structure 12 to overlap with the projection of the core module 11 in the direction perpendicular to the thickness direction X, and thus in the wearing state, the elastic metal wire 121 may clamp the ear and adhere to the ear together with the core module 11 due to elastic deformation.
In some embodiments, referring to
In some embodiments, an angle between the second inner side surface IS2 and the first inner side surface IS1 may be in a range of 119°-170°. If the angle is too small, the original intention of the earphone 10 to avoid the tragus may be violated; if the angle is too large, the fit degree between the earphone 10 and the skin of the user in the wearing state may be reduced.
In some embodiments, a distance between an end of the second inner side surface IS2 that is away from the core module 11 and the first inner side surface IS1 in the thickness direction X may be in a range of 1.6 mm-2.4 mm. If the distance is too small, the original intention of the earphone 10 to avoid the tragus may be violated; if the angle is too large, the fit between the earphone 10 and the skin of the user in the wearing state may be reduced.
In some embodiments, the transition portion 12a may include the adapter housing 122 connected with the core module 11. At least a portion of the adapter housing 122 may be disposed on the front side of the ear in the wearing state. In other words, the portion of the adapter housing 122 located on the front side of the ear in the wearing state may be regarded as a portion of the transition portion 12a or the entirety of the transition portion 12a. The adapter housing 122 may be configured as a tapered structure. For example, an area of an outer surface of the adapter housing 122 on a reference cross-section perpendicular to the length direction of the hook structure 12 may gradually decrease in a positive direction that is along the length direction of the hook structure 12 and points away from the core module 11. With such configuration, the transition portion 12a may also be configured as a tapered structure to make the earphone 10 smoother and more symmetrical in overall appearance.
In some embodiments, the adapter housing 122 may extend toward a side of the first inner side surface IS1 away from the outer side surface OS in the thickness direction X, so as to allow the earphone 10 to avoid the tragus in the wearing state, and allow a portion of the hook structure 12 to be staggered with a projection of the core module 11 in a direction that is perpendicular to the thickness direction X, such that in the wearing state, the upper ear root of the ear may provide a less supporting force to the earphone 10.
In some embodiments, in the non-wearing state, the elastic metal wire 121 may pass through a plane where the first inner side surface IS1 is located to allow a portion of the hook structure 12 to overlap with the projection of the core module 11 in the direction perpendicular to the thickness direction X, and then in the wearing state, the elastic metal wire 121 may clamp the ear and adhere to the ear together with the core module 11 due to elastic deformation.
In some embodiments, in the non-wearing state, the plane where the elastic metal wire 121 is located may intersect with the first inner side surface IS1, so as to allow a portion of the hook structure 12 to overlap with the projection of the core module 11 in the direction perpendicular to the thickness direction X, and then in the wearing state, the elastic metal wire 121 may clamp the ear and adhere to the ear together with the core module 11 due to elastic deformation. In the non-wearing state, an angle between the elastic metal wire 121 and the first inner side surface IS1 may be in a range of 15°-30°.
In some embodiments, the core housing 111 may include the core inner housing 1111 and the core outer housing 1112 connected with the core inner housing 1111. For example, the core inner housing 1111 and the core outer housing 1112 may be buckled in the thickness direction X. The core inner housing 1111 may be closer to the ear than the core outer housing 1112 in the wearing state, and the sound outlet 111a may be provided on the core inner housing 1111. In some embodiments, at least one of the core inner housing 1111 and the core outer housing 1112 may be plugged with the adapter housing 122 for fixation. For example, the core inner housing 1111 and the adapter housing 122 shown in
In some embodiments, the core housing 111 may include the core inner housing 1111 and the core outer housing 1112 connected with the core inner housing 1111. For example, the core inner housing 1111 and the core outer housing 1112 may be buckled in the thickness direction X. The core inner housing 1111 may be closer to the ear than the core outer housing 1112 in the wearing state. The sound outlet 111a may be provided on the core inner housing 1111. In some embodiments, one of the core inner housing 1111 and the core outer housing 1112 may be provided as an integrally formed structural member with the adapter housing 122, and the other of the core inner housing 1111 and the core outer housing 1112 may be fixedly connected with the integrally formed structural member. Accordingly, for the integrally formed structural member, a region corresponding to the loudspeaker 112 may be regarded as the core inner housing 1111, and a region provided in a tapered structure or a region corresponding to the electronic component 15 may be regarded as the adapter housing 122.
In some embodiments, referring to
In some embodiments, the electrode terminals 151 may face the front side of the ear in the wearing state, such that the electrode terminals 151 may be closer to the loudspeaker 112, which further shortens the distance between the electrode terminals 151 and the loudspeaker 112 in the length direction of the hook structure 12.
In some embodiments, the one or more electrode terminals 151 may include the positive charging terminal 1514 and the negative charging terminal 1515 which are spaced apart from each other. The positive charging terminal 1514 and the negative charging terminal 1515 may be respectively disposed in the respective through holes 1251 to facilitate charging of the earphone 10 through the electrode terminals 151.
In some embodiments, the one or more electrode terminals 151 may include a communication terminal 1516 spaced apart from the positive charging terminal 1514 and the negative charging terminal 1515. The communication terminal 1516 may be correspondingly disposed in the corresponding through hole 1251 to facilitate communication connection between the earphone 10 and the charging device such as the charging case.
In some embodiments, referring to
In some embodiments, when viewed along the extension direction of the electrode terminals 151, a connection line between every two of the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may form an unequal-sided triangle.
In some embodiments, when viewed along the extension direction of the electrode terminals 151, the positive charging terminal 1514, the communication terminal 1516, and the negative charging terminal 1515 may be spaced apart from each other in a straight line segment. When viewed along the extension direction of the electrode terminals 151, the magnet 127 and the core module 11 may be located on both sides of the straight line segment, respectively. In this way, when the earphone 10 is placed in the charging case, the magnetic circuit system of the loudspeaker 112 may form a first magnetic suction pair with a permanent magnet or a soft magnet in the charging case, and the magnet 127 may form a second magnetic suction pair with another permanent magnet or soft magnet in the charging case. Therefore, the electrode terminals 151 may be located between the first magnetic suction pair and the second magnetic suction pair to more reliably contact the electrode terminals in the charging case. In some embodiments, an area of an outer surface of the adapter housing 122 on a reference cross-section perpendicular to the length direction of the hook structure 12 may gradually decrease in a positive direction that is along the length direction of the hook structure 12 and points away from the core module 11, i.e., the adapter housing 122 may be set to a tapered structure to allow the transition portion 12a of the hook structure 12 to be set to a tapered structure, such that the overall appearance of the earphone 10 may be smoother and more symmetrical. A center of the magnet 127 may have a first distance, a second distance, and a third distance from a center of the positive charging terminal 1514, a center of the communication terminal 1516, and a center of the negative charging terminal 1515, respectively. The third distance may be greater than the first distance and greater than the second distance, respectively, which reduces the risk of the adapter housing 122 having too small a wall thickness due to the magnet 127 being too close to the negative charging terminal 1515, thereby increasing the structural strength of the adapter housing 122.
In some embodiments, referring to
In some embodiments, the core module 11 may include the main control circuit board 13 disposed in the core housing 111 and coupled with the loudspeaker 112. The main control circuit board 13 and the loudspeaker 112 may be stacked in the thickness direction X and the main control circuit board 13 may be located on a side of the loudspeaker 112 facing the outer side surface OS. In this way, when the size of the core housing 111 on the reference cross-section perpendicular to the thickness direction X is limited, the area of the loudspeaker 112 may be increased, and the loudspeaker 112 is closer to the permanent magnet or the soft magnet in the charging case, such that the suction force of the first magnetic attraction pair can be increased, and the electrode terminals 151 can more reliably contact the electrode terminals in the charging case.
According to the above description, the earphone 10 may include the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 which are spaced apart from each other. The positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be located on the same side of the ear in the wearing state. For example, the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be located on the front side of the ear. A spacing between the positive charging terminal 1514 and the negative charging terminal 1515 may be greater than a spacing between the positive charging terminal 1514 and the communication terminal 1516, and a spacing between the positive charging terminal 1514 and the communication terminal 1516 may be greater than a spacing between the communication terminal 1516 and the negative charging terminal 1515. The potential of the positive charging terminal 1514 is generally higher than the potential of the communication terminal 1516, and the communication terminal 1516 is generally more easily damaged by high voltage. In order to avoid or reduce the probability of damaging the communication terminal 1516 due to the conduction between the positive charging terminal 1514 and the communication terminal 1516 within a limited space, the spacing between the positive charging terminal 1514 and the communication terminal 1516 may be greater than the spacing between the communication terminal 1516 and the negative charging terminal 1515. In addition, in order to avoid or reduce the probability of damaging the earphone 10 due to a short circuit between the positive charging terminal 1514 and the negative charging terminal 1515, the spacing between the positive charging terminal 1514 and the negative charging terminal 1515 may be greater than the spacing between the communication terminal 1516 and the negative charging terminal 1515. In some embodiments, the spacing between the positive charging terminal 1514 and the negative charging terminal 1515 may be greater than the spacing between the positive charging terminal 1514 and the communication terminal 1516, such that the electrode terminals 151 can be arranged as concentrated as possible to reduce the space occupied by the electrode terminals 151, while minimizing the risk of short circuit of the electrode terminals 151 and minimizing the damage to the earphone 10.
In some embodiments, at least one of the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be disposed at the adapter housing 122. For example, the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be disposed at the adapter housing 122. As another example, the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be disposed at the battery housing 123.
In some embodiments, at least one of the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be disposed at the core housing 111. For example, one of the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be disposed at the core housing 111 and the remaining two of the positive charging terminal 1514, the negative charging terminal 1515, and the communication terminal 1516 may be disposed at the adapter housing 122.
In some embodiments, referring to
In some embodiments, the main control circuit board 13 and the loudspeaker 112 may be stacked on the winding axis of the first coil 1125. In this way, a larger loudspeaker 112 may be disposed in the core housing 111 when the volume of the core housing 111 is constant, thereby increasing the sensitivity and the maximum volume of the earphone 10. The winding axis of the second coil 134 and the winding axis of the first coil 1125 may be orthogonal. For example, the winding axis of the second coil 134 and the winding axis of the first coil 1125 may be respectively parallel to the length direction Y and the thickness direction X, so as to further weaken the mutual inductive coupling between the second coil 134 and the first coil 1125. In some embodiments, due to the weakening of the mutual inductive coupling between the second coil 134 and the first coil 1125, a spacing between the main control circuit board 13 and the loudspeaker 112 in the winding axis of the first coil 1125 may be further reduced, causing the core module 11 to be more compactly arranged in the thickness direction X, and reducing the volume of the core module 11. In some embodiments, the spacing between the main control circuit board 13 and the loudspeaker 112 in the winding axis of the first coil 1125 may be less than or equal to 3 mm. The second coil 134 may be disposed on a side of the main control circuit board 13 away from the loudspeaker 112 or on the other side toward the loudspeaker 112. For example, the second coil 134 may be disposed on aside of the main control circuit board 13 away from the loudspeaker 112, and the spacing between the main control circuit board 13 and the loudspeaker 112 in the winding axis of the first coil 1125 may be less than or equal to 1 mm. As another example, the second coil 134 may be disposed on the other side of the main circuit board 13 toward the loudspeaker 112, and the spacing between the main circuit board 13 and the loudspeaker 112 in the winding axis of the first coil 1125 may be less than or equal to 2 mm.
In the present disclosure, the core module 11 may include an inductor or a transceiver coil or other components. The inductor or the transceiver coil may include a second coil 134. In some embodiments, the core module 11 may include a switching power supply. The switching power supply may be configured to achieve voltage conversion. The switching power supply may be disposed on the main control circuit board 13 and electrically connected with the main control circuit board 13. An inductor of the switching power supply may be the second coil 134, which is configured to achieve energy storage, filtering, etc. In some embodiments, the core module 11 may include a communication device. The communication device may be configured to achieve the cooperative use of the earphone 10 with terminal devices such as a mobile phone and computer. The communication device may be disposed on the main control circuit board 13 and electrically connected with the main control circuit board 13. The communication device may include a transceiver coil to achieve signal transmission and reception. The transceiver coil of the communication device may be the second coil 134.

In some embodiments, an extension direction of the power wiring 1361 and an extension direction of the loop wiring 1362 may be set in parallel, such that the magnetic field generated by the power wiring 1361 and the magnetic field generated by the loop wiring 1362 may cancel each other. A thickness of the power wiring 1361 and wiring thickness of the loop wiring 1362 may be equal, thereby simplifying the molding process of the metal wiring 136. The width of the power wiring 1361 may be equal to the width of the loop wiring 1362, such that the magnetic field generated by the power wiring 1361 and the magnetic field generated by the loop wiring 1362 may cancel each other. In some embodiments, a length of the power wiring 1361 may be equal to a length of the loop wiring 1362, such that the magnetic field generated by the power wiring 1361 and the magnetic field generated by the loop wiring 1362 may cancel each other. It should be noted that the thickness of the loop wiring 1362 refers to a size of the loop wiring 1362 in a thickness direction (e.g., parallel to the thickness direction X) of the main control circuit board 13.
In some embodiments, the power wiring 1361 and the loop wiring 1362 may be disposed on the same layer on the substrate 135.
In some embodiments, the power wiring 1361 and the loop wiring 1362 may be disposed on different layers on the substrate 135, and orthographic projections of the power wiring 1361 and the loop wiring 1362 in the thickness direction of the main control circuit board 13 may at least partially overlap.
In some implementations, the load 137 may be a component such as a main control chip or a communication chip.
In some embodiments, the main control circuit board 13 may include a connector 138. The connector 138 may be disposed on the substrate 135 by means of surface mounting or other technologies. One end of the power wiring 1361 and one end of the loop wiring 1362 may be respectively connected with the connector 138, and the other end of the power wiring 1361 and the other end of the loop wiring 1362 may be respectively connected with the load 137, such that the load 137 may be connected with the external power supply.
