Description

TECHNICAL FIELD

The present invention belongs to the field of earphones, and specifically relates to a device of a polymeric bone conduction sound transmission component, a headset and a headset system.

BACKGROUND

Bone conduction sound transmission is a sound transmission method that converts sound into mechanical vibration of different frequencies and transmits sound waves through human skull, spiral organ, auditory center, etc. It uses the skull as a sound transmission carrier, does not need to be worn in the ear, and has less damage to hearing. Therefore, it has a wide range of applications. For example, bone conduction sound transmission devices can be mounted on products such as earphones, hats and glasses to achieve the purpose of sound transmission through bone conduction.

A traditional bone conduction sound transmission device is mainly composed of an outer housing, an electronic assembly, an inner housing, a sound generating unit and other components, and the sound generating unit is composed of a coil, a magnetic circuit structure and other components. In production of a bone conduction product, a plurality of components of the sound generating unit are assembled in the inner housing, and then the inner housing is fixed in the outer housing by means of gluing, and the outer housing can be directly in contact with the human skull. During operation of the device, the sound generating unit generates vibration as a whole and transmits the vibration to the outer housing. Since the sound generating unit has a large weight as a whole, the gluing between the inner housing and the outer housing may loosen during long-term vibration, and even the whole sound generating unit may be detached, resulting in sound breakage, damage and other problems of the bone conduction product. Moreover, it is also quite cumbersome to mount the sound generating unit in the inner housing.

The sound generating portion comprises a housing 1 and a sound generating unit 20, an accommodating cavity 103 is formed in the housing 1, and a plurality of components of the sound generating unit 20 are directly mounted in the accommodating cavity 103 without the need for separately wrapping around and providing an inner housing outside the sound generating unit 20, resulting in simpler assembly steps. Furthermore, during the operation of the sound generating unit 20, only some of the components vibrate, and weight of the vibrating components is small, which can reduce the risk of loose connection between the sound generating unit 20 and the housing 1 during operation.

The sound generating unit 20 comprises a coil 201 and a magnetic circuit structure 202, a mounting member 40 is provided in the housing 1, and the sound generating unit 20 can be in a first state or a second state depending on how the coil 201 and the magnetic circuit structure 202 are mounted in a mounting region 104.

In the first state of the sound generating unit 20, the magnetic circuit structure 202 is fixedly mounted in the housing 1 by the mounting member 40, and the coil 201 is fixed on an inner wall of the housing 1; in the first state, an audio electric signal is applied to the coil 201, the coil 201 remains fixed with respect to the housing 1, and the magnetic circuit structure 202 interacts with the coil 201 to cause the magnetic circuit structure 202 to generate vibrations and transmit the vibrations to the housing 1 by the mounting member 40 and then to the skull of a wearer to realize sound transmission.

In the second state of the sound generating unit 20, the coil 201 is fixedly mounted on the housing 1 by the mounting member 40, and the magnetic circuit structure 202 is fixed on the inner wall of the housing 1; in the second state, an audio electric signal is applied to the coil 201, the magnetic circuit structure 202 remains fixed with respect to the housing 1, and the coil 201 interacts with the magnetic circuit structure 202 to cause the coil 201 to generate vibrations and transmit the vibrations to the housing 1 by the mounting member 40 to realize sound transmission.

A relative position of the coil 201 and the magnetic circuit structure 202 remains unchanged regardless of whether the sound generating unit 20 is in the first state or in the second state, which is described in detail below taking the first state of the sound generating unit 20 as an example.

The housing 1 comprises a first outer housing 101 and a second outer housing 102, the first outer housing 101 and the second outer housing 102 are snap-fitted to each other and fixed by gluing, and a side surface of the second outer housing 102 away from the first outer housing 101 is directly fitted to the skull of the wearer. The first outer housing 101 and the second outer housing 102 form the accommodating cavity 103 therebetween, and the accommodating cavity 103 may be configured to accommodate the sound generating unit 20 and an electronic assembly. A side wall of the second outer housing 102 away from the first outer housing 101 is outwardly convex in a waist shape (the waist shape in this example refers to a pattern with semicircular arcs at both ends and parallel lines in the middle) to form the mounting region 104, the mounting region 104 is in the shape of a waist-shaped groove, and the coil 201 and the magnetic circuit structure 202 are both arranged in the mounting region 104.

In other application scenarios, the magnetic circuit structure 202 and the coil 201 may also be fixedly mounted on the first outer housing 101 and the second outer housing 102 respectively.

The sound generating unit 20 is contoured to match the shape of the mounting region 104. A side surface of the mounting region 104 away from the first outer housing 101 is a bottom wall of the mounting region 104, and a side surface perpendicular to the bottom wall thereof is a side wall of the mounting region 104. The side wall of the mounting region 104 is annular. The coil 201 is arranged close to the bottom wall of the mounting region 104, and the magnetic circuit structure 202 is mounted on a side of the coil 201 away from the bottom wall of the mounting region 104. The coil 201 is formed by winding a copper wire, and matches the shape of the mounting region 104. The magnetic circuit structure 202 comprises a base steel 2021, a magnet 2022 and a magnet pressing disc 2023, and the base steel 2021, the magnet 2022 and the magnet pressing disc 2023 are successively arranged along a direction close to the coil 201, and are glued and fixed to each other. The magnet 2022 extends into the coil 201 to apply an audio electrical signal to the coil 201, and the magnetic circuit structure 202 works with the coil 201 to cause the magnetic circuit structure 202 to vibrate.

In order to facilitate mounting of the coil 201, a first positioning structure is provided on the bottom wall of the mounting region 104, and a second positioning structure is provided on the coil 201. The first positioning structure and the second positioning structure are intermeshed with each other to realize positioning of the coil 201 to position and mount the coil 201 while limiting the coil during use to reduce the possibility of displacement of the coil 201.

The first positioning structure may be arranged in a concave, convex or combined concave-convex shape, and the second positioning structure matches the first positioning structure. The shapes of the first positioning structure and the second positioning structure are not limited thereto, and the first positioning structure and the second positioning structure may be arranged as any structure as long as the positioning of the coil 201 can be achieved.

In this example, the first positioning structure is arranged as a positioning raised edge 30, and the positioning raised edge 30 is in a waist-shaped annular shape and is integrally formed with the second outer housing 102; the second positioning structure is arranged as a positioning groove 2011, the positioning groove 2011 is arranged on an inner side of a side of the coil 201 close to the bottom wall of the mounting region 104, the coil 201 is sheathed and positioned on the positioning raised edge 30 by the positioning groove 2011, two mutually perpendicular side walls of the positioning groove 2011 are respectively fitted to two mutually perpendicular side walls of the positioning raised edge 30, and positions where the positioning groove 2011 are fitted to the positioning raised edge 30 are glued for fixing to realize fixed mounting of the coil 201.

The magnetic circuit structure 202 is mounted on the second outer housing 102 by the mounting member 40, and the mounting member 40 is glued and fixed to the base steel 2021 of the magnetic circuit structure 202, and the magnetic circuit structure 202 is connected with the second outer housing 102 by the mounting member 40. In this example, the mounting member 40 is arranged as a fixing plate 401, the fixing plate 401 is in the shape of a waist-shaped plate, an annular edge of the fixing plate 401 is fixed on the second outer housing 102, and a middle portion of the fixing plate 401 is fixedly connected with the magnetic circuit structure 202, so that the mounting of the magnetic circuit structure 202 can be realized.

In order to facilitate positioning and mounting of the fixing plate 401, a third positioning structure is provided on the side wall of the mounting region 104 away from the bottom wall of the mounting region 104, the third positioning structure can be arranged in a concave, convex or combined concave-convex shape, and the fixing plate 401 is matches the third positioning structure to realize the positioning of the fixing plate 401. After the fixing plate 401 is positioned, the magnet 2022 of the magnetic circuit structure 202 is partially located in the coil 201, and the third positioning structure can limit displacement of the fixing plate 401 in a direction in which a plate surface thereof extends, thus reducing the probability of collision and interference between the magnetic circuit structure 202 and the coil 201. Of course, the shape of the third positioning structure is not limited thereto, and the third positioning structure may be arranged in any structure as long as the positioning of the fixing plate 401 and thus the magnetic circuit structure 202 can be achieved.

In this example, the third positioning structure is arranged as a limiting groove 501; firstly, a mounting step 50 is integrally provided on an inner wall of the second outer housing 102, and the limiting groove 501 is arranged on the mounting step 50; and the edge of the fixing plate 401 is embedded in the limiting groove 501, and the limiting groove 501 can limit the displacement of the fixing plate 401 in the direction in which the plate surface thereof extends, so that the magnetic circuit structure 202 can be positioned.

A position where the fixing plate 401 is fitted to the side wall of the limiting groove 501 can be fixed by gluing; the plate surface of the fixing plate 401 is arranged as a complete and continuous plane; therefore, a gluing region between the fixing plate 401 and the housing 1 is provided continuously along the edge of the fixing plate 401; a gluing region between the fixing plate 401 and the side wall of the limiting groove 501 is larger; and the fixing plate 401 is more stably mounted on the housing 1.

In other application scenarios, the gluing region between the fixing plate 401 and the side wall of the limiting groove 501 can be reduced. For example, serrations and notches can be provided along the annular edge of the fixing plate 401, or a plurality of through holes can be provided along the position where the fixing plate 401 is fitted to the side wall of the limiting groove 501, or other structures can be used to reduce contact and gluing area between the edge of the fixing plate 401 and the second outer housing 102, thereby achieving the effects of improving sensitivity of the sound generating unit 20 and reducing power consumption.

In this example, a waist-shaped protrusion is provided on the second outer housing 102 to form the waist-shaped mounting region 104, and the shapes of such components as the coil 201 and the magnetic circuit structure 202 match the shape of the mounting region 104. In other application scenarios, the waist-shaped protrusion on the second outer housing 102 may also be arranged in a circular, elliptical, polygonal or irregular shape, and may form mounting regions 104 with different contour shapes, and the shapes of such components as the coil 201 and the magnetic circuit structure 202 may be adjusted accordingly. Of course, the protrusion may not be arranged on the second outer housing 102.

In this example, the mounting member 40 is arranged as the fixing plate 401, and an amplitude of the fixing plate 401 is limited when the magnetic circuit structure 202 vibrates, which results in better transmission of medium- and high-frequency sound.

The implementation principle is as follows: at the time of assembly, an opening of the second outer housing 102 is first placed upward, the coil 201 component is placed inside the second outer housing 102, and the coil 201 is mounted by means of the positioning convex edge 30; and then, the fixing plate 401 having the magnetic circuit structure 202 is mounted in the limiting groove 501 (the fixing plate 401 and the magnetic circuit structure 202 can be fixed when the magnetic circuit structure 202 is assembled), thus realizing mounting of the sound generating unit 20 through simple operation.

It should be noted that the above-mentioned sound generating portion may be applied to a headset of this example, and may also be applied alone or in other headset products.

In addition, as shown in FIGS. 1-5, the device further comprises a button portion, and in addition to the housing 1, the button portion further comprises a manipulation button 2 and an elastic layer 3 (annular); the manipulation button 2 is made of a hard material (e.g., a plastic button, a metal button, etc.), the elastic layer 3 is made of an elastic material (e.g., a rubber material, etc.), the manipulation button 2 is located on an inner circumference of the elastic layer 3 and the both are in embedded connection with each other; and the housing 1 is located on an outer circumference of the elastic layer 3 and the both are in embedded connection with each other. In addition, a right end of the manipulation button 2 is integrally formed and convexly provided with a cylindrical action portion 21. The device further comprises an electronic button 4; the electronic button 4 is fixedly arranged on the housing 1, the electronic button 4 is located on a right side of the manipulation button 2, a force-receiving portion 41 is arranged on a left side of the electronic button 4, and the force-receiving portion 41 is directly opposite to the action portion 21; and there is a spacing between the action portion 21 and the force-receiving portion 41, and the spacing is s1.

When the manipulation button 2 is pressed rightward, the action portion 21 moves towards the force-receiving portion 41 and presses the force-receiving portion 41, thus performing manipulation of the electronic button 4, while the elastic layer 3 is deformed to store elastic potential energy; and when the manipulation button 2 is released, that is, when the manipulation button 2 is not pressed, the elastic layer 3 elastically resets so that the action portion 21 moves away from the force-receiving portion 41 toward the left to release the action portion from the force-receiving portion.

Therefore, 1. the manipulation button 2 is pressed to move the action portion 21 to the force-receiving portion 41 by a stroke of s1, and then directly acts on the force-receiving portion 41 to move the force-receiving portion 41 by a certain stroke to realize manipulation of the electronic button 4; since the action portion 21 and the force-receiving portion 41 are both made of hard materials, the manipulation stroke is constant, and a change in the manipulation stroke due to the material of the elastic layer 3 does not occur, so that the user has a better manipulation feeling; 2. the manipulation button 2 is connected with the housing 1 by the elastic layer 3, and the manipulation button 2 is less affected when the housing 1 vibrates, thus resulting in a smaller amplitude, better stabilization and less likelihood to come into contact with the electronic button 4 which may cause inadvertent activation of the electronic button 4, and the spacing s1 between the action portion 21 and the force-receiving portion 41 can ensure that the action portion 21 does not come into contact with the force-receiving portion 41 to prevent inadvertent activation when the electronic button 4 vibrates; and 3. the action portion 21 and the force-receiving portion 41 facing each other make the transmission of force more direct, and the manipulation button 2 is less likely to be skewed, which further optimizes the manipulation feeling.

Specifically, in this example, the elastic layer 3 comprises a deformation ring portion 31 surrounding an outer circumference of the manipulation button 2, the deformation ring portion 31 is arranged to extend radially inward along a direction of the force-receiving portion 41 towards the action portion 21, and an included angle between the deformation ring portion 31 and an axial direction thereof is a, with 1°≤a≤89°, so that the inclined deformation ring portion 31 stores the elastic potential energy for resetting to the left when the manipulation button 2 is pressed rightward, resulting in smoother resetting.

In addition, in this example, an inner circumference of the deformation ring portion 31 is provided with an inner connecting portion 32 surrounding and covering the manipulation button 2, an inner circumference of the inner connecting portion 32 is provided with a first fitting surface 321 in a cylindrical shape, and the manipulation button 2 is provided with a second fitting surface 22 that matches the first fitting surface 321; and the first fitting surface 321 is inwards convexly provided with a reinforcing protrusion 322, and the second fitting surface 22 is concavely provided with a reinforcing recess 23 for inserting the reinforcing protrusion 322. Therefore, 1. the inner connecting portion 32 surrounds and covers the manipulation button 2 to serve as a first connection, and fit between the reinforcing protrusion 322 and the reinforcing recess 23 serves as a second connection, which result in better connection strength; and 2. the fit between the first fitting surface 321 and the second fitting surface 22 allow plane-plane fit, which results in better sealing effect.

The first fitting surface 321 and the second fitting surface 22 may also be truncated cone-shaped or cone-shaped.

Preferably, in this example, the reinforcing protrusion 322 is arranged in an annular shape, an inner circumference of the reinforcing protrusion 322 is provided with a first mating cambered surface 323, a shape and size of the reinforcing recess 23 are adapted to a shape and size of the reinforcing protrusion 322, and a second mating cambered surface 24 is provided in the reinforcing recess 23 corresponding to the first mating cambered surface 323. Therefore, 1. the annular reinforcing protrusion 322 and the annular reinforcing recess 23 achieve more convenient mutual fit, and a circumferential fit can further improve the sealing effect of the manipulation button 2 and the inner connecting portion 32; and 2. the fit between the first mating cambered surface 323 and the second mating cambered surface 24 is made tighter through arc-shaped mating, preventing right angle bending which results in incomplete filling.

Specifically, in this example, the housing 1 comprises a first half housing 11 (left side), a second half housing 12 (right side) and a first circuit board 13, the electronic button 4 is arranged on the first circuit board 13 and fixed by pin welding, the first circuit board 13 is clamped between the first half housing 11 and the second half housing 12, and the first half housing 11 and the second half housing 12 are fixed by bolting, snap-in or bonding, so that the three are fixedly connected.

In addition, in this example, an outer circumference of the deformation ring portion 31 is provided with an annular outer connecting portion 33, an axial end of the outer connecting portion 33 abuts against the first circuit board 13, and the other end abuts against the first half housing 11, so that the deformation ring portion 31 is mounted with the outer connecting portion 33 clamped and limited by the first half housing 11 and the first circuit board 13, and is sealed by pressing.

Specifically, in this example, a right side of the first half housing 11 is provided with an annular snap-in recess 111, and the outer connecting portion 33 partially extends into the snap-in recess 111; and in addition, a side of the deformation ring portion 31 facing the outer connecting portion 33 is arranged at one end of an inner circumference of the outer connecting portion 33 facing the first circuit board 13. Therefore, 1. the snap-in recess 111 is arranged so that the outer connecting portion 33 is partially confined in the snap-in recess 111 and is radially limited by the snap-in recess 111, thereby improving mounting stability; and 2. the deformation ring portion 31 is arranged at one end of the inner circumference of the outer connecting portion 33 facing the first circuit board 13, which maximizes a volume of the outer connecting portion 33 entering the snap-in recess 111, maximizes connection stability, and allows the deformation ring portion 31 to be further away from the first half housing 11 to prevent the deformation ring portion 31 from coming into contact with the first half housing 11 for a long time in a non-pressed state resulting in bonding.

The first half housing 11 is provided with a housing ring portion 112 on a radial inner side located in the snap-in recess 111, an end of the housing ring portion 112 facing the deformation ring portion 31 is provided with an inclined ring surface 113, the inclined ring surface 113 is arranged inclined radially inward along the direction of the force-receiving portion 41 facing the action portion 21, and a separation gap 114 is provided between the inclined ring surface 113 and the deformation ring portion 31, so that the inclined ring surface 113 is adapted to an inclination direction of the deformation ring portion 31, so that a spacing therebetween is more constant and difficult to contact to prevent the deformation ring portion 31 from coming into contact with the first half housing 11 for a long time in the non-pressed state resulting in bonding.

Preferably, in this example, a surface of the housing 1 (the first half housing 11) is provided with a built-in cavity 115, the manipulation button 2 is arranged in the built-in cavity 115, and there is a spacing between an outer circumferential wall of the manipulation button 2 and an inner circumferential wall of the built-in cavity 115, and the spacing is s2, with s2≤2 mm.

Therefore, the built-in cavity 115 is arranged to allow the manipulation button 2 to be built in and not easily actuated inadvertently, while the spacing s2 ensures that the manipulation button 2 does not come into contact with the housing 1 when the housing 1 vibrates, so that the manipulation button 2 is less affected, thus resulting in a smaller amplitude, better stabilization and less likelihood to come into contact with the electronic button 4 which may cause inadvertent activation of the electronic button 4.

Preferably, in this example, s1 is ≤1.5 mm.

It should be noted that the above-mentioned button portion may be applied to the headset of this example, and may also be applied alone or in other headset products.

Example 3

A device of a polymeric bone conduction sound transmission component, has a main structure the same as that of Example 1, and differences lie in that the number of reinforcing protrusions 322 and reinforcing recesses 23 is several, and they are arranged at equal intervals along a circumferential direction of the inner connecting portion 32, so that the fit between the reinforcing protrusions 322 and the reinforcing recesses 23 also has the function of circumferential limiting.

A headset, has a main structure the same as that of Example 2, and has the same differences from Example 1 as described previously in this example.

Example 4

As shown in FIGS. 13-14, a device of a polymeric bone conduction sound transmission component, has a main structure the same as that of Example 1, and differences lie in that the mounting member 40 is arranged as a vibrating plate 5, the base steel 2021 of the magnetic circuit structure 202 is fitted and glued to the vibrating plate 5 for fixation, and the magnetic circuit structure 202 is mounted in the housing 1 by the vibrating plate 5.

The vibrating plate 5 is in the shape of a waist plate, and the vibrating plate 5 is composed of a fixing portion 6, connecting portions 7 and a vibration portion 8; the fixing portion 6 is in a waist-shaped annular shape, the vibration portion 8 is in the waist-shaped plate shape, and the vibration portion 8 is arranged in an annular structure of the fixing portion 6 and matches the shape of the fixing portion 6; the connecting portions 7 are arranged between the fixing portion 6 and the vibration portion 8, four connecting portions 7 are provided in total, and the four connecting portions 7 are symmetrically arranged along a width direction and a length direction of the vibrating plate 5; the connecting portion 7 extends outward from a short edge of an edge of the vibration portion 8 in a length direction of the vibration portion 8, then wraps around to a middle position of a long edge of the vibration portion 8 and extends outward to the fixing portion 6; and an outer ring edge of the fixing portion 6 is fixed on the side wall of the limiting groove 501 by gluing, an audio electric signal is applied to the coil 201, and the magnetic circuit structure 202 works with the coil 201 to cause the magnetic circuit structure 202 to vibrate, thereby driving the vibration portion 8 of the vibrating plate 5 to vibrate in a thickness direction thereof.

The fixing portion 6 has a same structure as that of the edge of the fixing plate 401, that is, through holes, notches, serrations or other structures may be provided on the fixing portion 6 to reduce a connection area of the fixing portion 6 and the housing 1. In this example, the fixing portion 6 is provided with a ring of through-holes thereon, and vibration generated by the magnetic circuit structure 202 is transmitted to the housing 1 by the vibrating plate 5 and is more concentrated, so that sensitivity of the sound generating unit 20 can be improved.

Since an edge of the vibrating plate 5 is fixed, when vibration amplitude of the magnetic circuit structure 202 and the vibration portion 8 is large, deformation of the vibrating plate 5 is large, and the magnetic circuit structure 202 and the connecting portion 7 may collide. In order to reduce the possibility that the magnetic circuit structure 202 collides with the connecting portion 7, the area of a plate surface of the vibration portion 8 may be enlarged so that the vibration portion 8 can completely cover the magnetic circuit structure 202, that is, an orthogonal projection of the magnetic circuit structure 202 on the plate surface of the vibration portion 8 is located entirely within the plate surface of the vibration portion 8.

In this example, the mounting member 40 is arranged as the vibrating plate 5, and the vibrating plate 5 can vibrate with the magnetic circuit structure 202, which produces better effect on transmission of medium- and low-frequency sound.

With reference to FIG. 15, in other application scenarios, the sound generating unit 20 is in a second state, the mounting member 40 is arranged as a vibrating plate 5, the coil 201 is mounted on the second housing 102 by the vibrating plate 5, and the vibrating plate 5 can vibrate with the coil 201 and transmit the vibration to the housing 1.

A headset, has a main structure the same as that of Example 2, and has the same differences from Example 1 as described previously in this example.

Example 5

As shown in FIGS. 16-17, a device of a polymeric bone conduction sound transmission component, has a main structure the same as that of the device of the polymeric bone conduction sound transmission component according to Example 4, and differences lie in that a separator is provided between the vibrating plate 5 and the magnetic circuit structure 202, and the separator can connect the vibrating plate 5 and the magnetic circuit structure 202 to each other, so that a gap is formed between the vibrating plate 5 and the magnetic circuit structure 202, and the gap is a vibration gap, and the vibration gap can provide a vibration space for the vibration portion 8, thereby reducing the probability that the magnetic circuit structure 202 collides with the connecting portion 7 without enlarging the area of the plate surface of the vibration portion 8.

In this example, the spacer is arranged as a gasket 60, the gasket 60 is in a waist-shaped plate shape, a thickness of the gasket 60 is greater than a thickness of the vibrating plate 5, and both sides of the gasket 60 are respectively glued and fixed to the base steel 2021 and the vibrating plate 5; and in production, the magnetic circuit structure 202 and the gasket 60 may be fixed to each other, and then the gasket 60 may be fixed to the vibrating plate 5.

In order to facilitate positioning and mounting of the spacer 60 and the vibrating plate 5, a fourth positioning structure is provided on the spacer 60, and a fifth positioning structure is provided on the vibration portion 8 of the vibrating plate 5, and the fourth positioning structure and the fifth positioning structure are intermeshed with each other to achieve positioning. Specifically, the fourth positioning structure may be arranged in a concave, convex or combined concave-convex shape, the fifth positioning structure matches the fourth positioning structure, the shape of the fourth positioning structure and the fifth positioning structure is not limited thereto, and the fourth positioning structure and the fifth positioning structure may be arranged in any structure as long as mutual positioning of the vibration portion 8 and the gasket 60 can be achieved.

In this example, the fourth positioning structure is arranged as a positioning post 601, a plurality of positioning posts 601 are integrally arranged on a surface of the gasket 60 fitted to the vibrating plate 5, and the positioning posts 601 are arranged as a cylindrical shape; and the fifth positioning structure is arranged as a positioning groove 40231, a plurality of positioning grooves 40231 are arranged on the vibration portion 8 in a penetrating manner, the positioning grooves 40231 are arranged as circular through grooves, and the positioning grooves 40231 correspond to the positioning posts 601 on a one-to-one basis. In this example, seven positioning posts 601 are provided in total, one of the positioning posts 601 corresponds to a central position of the vibrating plate 5, and the other six positioning posts 601 have identical diameter and are equally divided into two groups, the two groups of positioning posts 601 are spaced apart along a length direction of the vibrating plate 5 and are symmetrically arranged, and the diameter of the positioning post 601 at the central position of the vibrating plate 5 is greater than the diameters of the other six positioning posts 601; and the positioning posts 601 are inserted into the positioning grooves 40231 in a one-to-one manner to realize the positioning of the spacer 60 and the vibrating plate 5, which is more conducive to the assembly of the magnetic circuit structure 202 and the vibrating plate 5, and also can reduce the probability of transverse displacement between the vibrating plate 5 and the magnetic circuit structure 202.

In this example, since a size of the sound generating unit 20 in a thickness direction of the vibrating plate 5 is increased by the addition of the spacer 60, the size of the mounting region 104, the limiting groove 501 and the like can be adapted accordingly by those skilled in the art.

In this example, during operation of the device, the coil 201 is fixed relative to the housing 1, the magnetic circuit structure 202 vibrates, and the vibration of the magnetic circuit structure 202 is directly transmitted to the housing 1 by the mounting member 40, and is finally transmitted to the skull of the wearer. Compared with a traditional structure (the sound generating unit 20 is polymerized in an inner housing and then fixed on an outer housing), the structure in this example does not need to pass through the inner housing 1 in the process of vibration transmission, resulting in more direct transmission of vibration and less energy loss. In addition, during the operation of the device, only the magnetic circuit structure 202 vibrates (in the traditional structure, the whole sound generating unit 20 vibrates), weight of the vibrating component is small, the energy loss is small, and the risk of loose connection between the vibrating portion 8 and the housing 1 is low.

Referring to FIG. 18, which is a comparison of frequency response of the structure according to this example and the traditional structure, it can be seen that a sound pressure value of the structure disclosed in the present application is significantly higher than that of the traditional structure at medium and low frequencies.

With reference to FIG. 19, in other application scenarios, the sound generating unit 20 is in a second state, the mounting member 40 is arranged as a vibrating plate 5, and the coil 201 is mounted on the second housing 102 by the vibrating plate 5; a spacer is provided between the coil 201 and the vibrating plate 5, the spacer is arranged as a gasket 60, the vibrating plate 5 is connected with the coil 201 by the gasket 60, and the gasket 60 is arranged so that a vibration gap is provided for the vibrating plate 5; and the vibrating plate 5 may vibrate with the coil 201 and transmit the vibration to the housing 1.

A headset, has a main structure the same as that of the headset in Example 4, and has the same differences from the device of the polymeric bone conduction sound transmission component according to Example 4 as described previously in this example.

Example 6

As shown in FIGS. 20-22, a device of a polymeric bone conduction sound transmission component, has a main structure the same as that of the device of the polymeric bone conduction sound transmission component in Example 4 or the device of a polymeric bone conduction sound transmission component in Example 5, and differences lie in that the fixing portion 6 is arranged in a annular shape, and an inner annular shape and an outer annular shape of the fixing portion 6 are both in a racetrack shape; the connecting portions 7 are arranged on an inner circumference of the fixing portion 6, and the number thereof is 4; the vibration portion 8 is arranged on the inner circumference of the fixing portion 6, and an outer circumference of the vibration portion 8 is arranged in a racetrack shape, wherein a connecting position 81 (4 places) is provided at an intersection of each of straight-line segments and each of semicircular arc segments of the vibration portion 8; and one end of each of the connecting portions 7 is connected to a corresponding connecting position 81, and the other end is connected with the fixing portion 6.

Therefore, 1. the vibration portion 8 with the racetrack-shaped outer circumference can be changed in shape by adjusting a length of the straight-line segments and adjusting radius of the semicircular arc segments to adapt to the fixing portion 6 with a different shape, so that the fixing portion 6 adapted to the shape of a vibrator can better matches the vibrator; and 2. the connecting positions 81 are arranged at the intersection of each of the straight-line segments and each of the semicircular arc segments of the vibration portion 8, so that the connecting portions 7 are connected to the connecting positions 81 without stress concentration, thereby improving overall connection strength of the vibrating plate 5.

Each of the connecting portions 7 comprises a fixing segment 71 connected with the fixing portion 6, a vibration segment 72 connected with the vibration portion 8, and a main connecting segment 73 located between the fixing segment 71 and the vibration segment 72, so that the connecting portion 7 is connected with the fixing portion 6 and the vibration portion 8 by the fixing segment 71 and the vibration segment 72, and the main connecting segment 73 is structured to have an adaptive vibration performance.

The inner circumference of the fixing portion 6 in this example comprises a first spatial domain 61 located on one side (upper and lower sides) of each of the straight-line segments of the vibration portion 8 and a second spatial domain 62 located on one side (left and right sides) of each of the semicircular arc segments of the vibration portion 8 so as to divide an inner space into four regions, and the connecting portions 7 are arranged orderly in the four regions according to specific requirements.

Specifically, in this example, each of the main connecting segments 73 comprises a U-shaped first section 731 (located in the first spatial domain 61) and a W-shaped second section 732 (located in the second spatial domain 62), wherein each of the first sections 731 comprises two first extension segments 7311 (straight-lines extending in a left-right direction) and a first reverse arc segment 7312 connecting same sides of the two first extension segments 7311, wherein each of the second sections 732 comprises four second extension segments 7321 (straight-lines extending in a left-right direction) and a second reverse arc segment 7322 connecting same side of adjacent second extension segments 7321, and wherein the second extension segments 7321 are arranged apart up and down. In addition, the vibration segment 72 is arranged at one end of the first section 731, the fixing segment 71 is arranged at one end of the second section 732, and the other end of the first section 731 and the other end of the second section 732 are connected with a linking segment 733 therebetween, and the linking segment 733 has an arc shape extending in a circumferential direction of the semicircular arc segment of the fixing portion 6.

Therefore, 1. the first section 731, the second section 732 and the linking segment 733 are combined to form the main connecting segment 73 having a multi-fold type, and effective utilization of spaces in the first spatial domain 61 and the second spatial domain 62 results in sufficient length sufficient so as to ensure that the vibrating plate 5 has sufficient vibration performance; 2. the arc-shaped arrangement of the linking segment 733 allows it better to use the shape of the semicircular arc segment of the vibration portion 8, resulting in a more compact structure to make room for the arrangement of the first section 731 and the second section 732; and 3. the first extension segment 7311 is a straight-line extending in a left-right direction, which allows rational use of the straight-line of the vibration portion 8 extending in the left-right direction, and results in a simple structure, and optimizes the length of the first extension segment 7311 to increase the length of the main connecting segment 73 and thus to optimize the vibration performance; and the second extension segment 7321 is a straight-line extending in a left-right direction and is arranged up and down, which results in a more ordered and simple structure.

Preferably, in this example, a U-shaped opening of the first section 731 faces the adjacent second spatial domain 62, while a W-shaped double opening of the second section 732 faces the vibration portion 8 in a left-right direction, so that one end of the first section 731 which needs to be connected with the second section 732 faces the second spatial domain 62, and one end of the second section 732 which needs to be connected with the first section 731 faces the vibration portion 8 to achieve a shorter spacing therebetween, so that the linking segment 733 can connect them more smoothly, resulting in a more orderly and compact structure.

A length of each of the connecting portions 7 is L, and a thickness of the vibrating plate 5 is D, with L/D≥3, and D<5 mm.

Preferably, in this example, an axial compliance of the vibrating plate 5 is greater than a radial compliance, and the greater the axial compliance of the vibrating plate 5, the better the low-frequency effect is, and thus the frequency response effect of the vibrator can be effectively improved.

It should be noted that the vibrating plate in this example can be applied to the headset of this example, and may also be applied alone or in other headset products.

A headset, has a main structure the same as that of the headset in Example 4 or the headset in Example 5, and has the same differences from the device of the polymeric bone conduction sound transmission component in Example 4 or the device of the polymeric bone conduction sound transmission component in Example 5 as described previously in this example.

In addition, since the main connection segment 73 is not arranged in the second spatial domain 62, positions of the left and right sides of the fixing portion 6 can be adjusted according to requirements to shorten an entire left-right length of the vibrating plate 5.

Example 18

As shown in FIGS. 32-35, the present invention discloses a magnetic attraction connection structure, comprising: a connecting main portion 1.0, wherein a lower end thereof is downwards convexly provided with a plug-in protrusion 1.1, a lower end of the plug-in protrusion 1.1 is provided with a mounting surface 1.11, one end of the plug-in protrusion 1.1 located on the mounting surface 1.11 is convexly provided with a protective protrusion 2.0, and one end of the protective protrusion 2.0 facing away from the mounting surface 1.11 is provided with a magnetic attraction surface 2.1; and a plurality of connectors 3.0 which are fitted to the connecting main portion 1.0, and at least one of the connectors 3.0 and the other of the connectors 3.0 are arranged circumferentially on an outer circumference of the protective protrusion 2.0, and each of the connectors 3.0 is located on a side of the magnetic attraction surface 2.1 facing the mounting surface 1.11.

Therefore, 1. the magnetic attraction surface 2.1 is arranged on the protective protrusion 2.0, and the connectors 3.0 are separated in the middle by the protective protrusion 2.0 to increase a spacing between the connectors 3.0, so that upon magnetic attraction of a magnetically attractable object by the magnetic attraction surface 2.1, the magnetically attractable object is not easily shorted to the connector 3.0 to prevent the connectors 3.0 from shorting leading to line disorder; 2. the protective protrusion 2.0 is arranged protruding from the plug-in connector, so that the connector 3.0 is located on the side of the magnetic attraction surface 2.1 facing the mounting surface 1.11, thus a high-low misalignment between the magnetic attraction surface 2.1 and the connector 3.0 is achieved by means of the protruding structure, and upon the magnetic attraction of the magnetically attractable object on the magnetic attraction surface 2.1, the magnetically attractable body is not easily shorted to the connectors 3.0 to prevent the line disorder due to the shorting of the connectors 3.0; and 3. circumferential arrangement of the connectors 3.0 not only ensures that all the connectors 3.0 are located on the outer circumference of the protective protrusion 2.0, but also allows a greater spacing between the connectors 3.0 that are not allowed to be shorted.

Thus, the slidably arranged connector 3.0 works with the reset member 4.0 to ensure an elastic fit between the connector 3.0 and the corresponding connected component (e.g., a mating member 7.0 in a headset system), resulting in a smoother connection.

In other examples, the connector 3.0 is fixedly mounted in the corresponding mounting hole 1.12 by means of threaded connection, snap-fit, etc.

In addition, in this example, the number of connectors 3.0 is 2, the connectors 3.0 can be a first functional member 3.2 (charging) or a second functional member 3.3 (data connection), and the two connectors 3.0 are arranged on opposite sides (left and right) of the protective protrusion 2.0, and when the number of connectors 3.0 is 2, a spacing between the two connectors 3.0 is maximized.

Specifically, in this example, an outer circumference of the plug-in protrusion 1.1 is in a racetrack shape, and the plug-in protrusion 1.1 comprises a straight-line portion 1.14 in the middle and circular arc portions 1.15 on left and right sides; the protective protrusion 2.0 is arranged on the straight-line portion 1.14, and the two connectors 3.0 are arranged on the circular arc portions 1.15 on the left and right sides; and the plug-in protrusion 1.1 is made to take advantage of the racetrack-shaped structure to allow for a smoother fit with a corresponding connected component (e.g., a plug-in recess 6.1 in a headphone system).

In other examples, the outer circumference of the plug-in protrusion 1.1 is in the shape of quadrangular prism, a square frustum, etc.

In addition, both sides of the protective protrusion 2.0 are provided with an integral surface 2.2 coplanar with an outer circumferential surface of the corresponding straight-line portion 1.14, so that the integral surface 2.2 is coplanar with the outer circumferential surface of the straight-line portion 1.14 to achieve a more compact structure.

Therefore, the connectors 3.0 can realize not only a charging function but also a data connection function, with various functions; and the first functional member 3.2 and the second functional member 3.3 have different functions, and shorting does not cause line disorder, so that left-right arrangement results in a more compact structure.
