This application is based on and claims priority to the Chinese Patent Application No. 202111045769.1 filed on Sep. 7, 2021, the entire content of which is incorporated herein as reference for all purposes.
The present disclosure relates to the field of earphone box technologies, and more particularly, to an earphone box and an earphone.
Existing TWS (true wireless stereo) earphones are mainly classified into two types: i.e., earphones with a bud shape and earphones with a stem shape. The earphone is in contact with and compresses a pogopin (may be referred as pogo pin) in an earphone box by a copper column on the earphone when it is placed into the earphone box, to realize a charging process to the earphone by the earphone box. In order to ensure that the copper column of the earphone are in full contact with the pogopin of the earphone box to realize the charging of the earphone when the earphone is placed into the earphone box, it is typically implemented by the following ways: an inner housing of the earphone box has a shape similar to a shape of the earphone; a position of the earphone in the earphone box is restricted by the shape; moreover, in order to ensure the charging reliability of the placed earphone, the copper column of the earphone and the pogopin of the earphone charging box are both oriented along a vertical direction, which is consistent with the gravity direction of the earphone, to reduce a mutual dislocation between the copper column and the pogopin caused by the gravity component.
An earphone box according to the present disclosure includes a box body and a box magnet. The box body defines an accommodating groove for accommodating the earphone, and the accommodating groove is provided with an interface electrically coupled to the earphone. The box magnet is mounted on the box body and configured as a multipole magnet, the earphone is provided with an earphone magnet with the same number of poles as the box magnet, and the box magnet is configured to attract and couple with the earphone magnet. The attraction coupling face of the box magnet is an inclined face.
An earphone according to the present disclosure includes an earphone body configured as a bud shape, and the earphone body is adapted to fit in an accommodating groove of an earphone box. The earphone box includes a box body and a box magnet. The box body defines an accommodating groove for accommodating the earphone, and the accommodating groove is provided with an interface electrically coupled to the earphone. The box magnet is mounted on the box body and configured as a multipole magnet, the earphone is provided with an earphone magnet with the same number of poles as the box magnet, and the box magnet is configured to attract and couple with the earphone magnet. The attraction coupling face of the box magnet is an inclined face.
Embodiments of the present disclosure are described in detail below, and examples of the described embodiments are illustrated in accompanying drawings. The following embodiments described with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, rather than limit the present disclosure.
An earphone box 1000 according to examples of the present disclosure is described below with reference to the accompanying drawings.
As illustrated in
The box body 1001 defines an accommodating groove 100 for accommodating an earphone 300, and the accommodating groove 100 is provided with an interface 130 electrically coupled to the earphone 300.
The box magnet 200 is mounted on the box body 1001, and is configured as a multipole magnet. The box magnet 200 is a planar multipole magnet, i.e., an attraction face of the box magnet 200 has at least one pair of poles (one N pole and one S pole). The earphone 300 is provided with an earphone magnet 310 with the same number of poles as the box magnet 200. Therefore, an attraction face of the earphone magnet 310 also has at least one pair of poles. Moreover, a number of poles of the earphone magnet 310 and a number of poles of the box magnet 200 are the same. That is, when the box magnet 200 is a four-pole magnet, the earphone magnet 310 is also a four-pole magnet; when the box magnet 200 is a two-pole magnet, the earphone magnet 310 is also a two-pole magnet. The earphone magnet 310 attracts and couples with the box magnet 200, so that the earphone 300 can be fixed in the accommodating groove 100 and arranged obliquely relative to the box body 1001.
An earphone box in the related art has following disadvantages: a low utilization rate of an internal space, a large overall volume and the inconvenient carrying, and the earphone is inconvenient to take out of the earphone box.
In the earphone box 1000 according to the examples of the present disclosure, since the box body 1001 is provided with the box magnet 200 configured as the multipole magnet and the earphone 300 is provided with the earphone magnet 310 with the same number of poles as the box magnet 200, the attraction face of the box magnet 200 has at least one pair of poles, and the attraction face of the earphone magnet 310 also has at least one pair of poles. Moreover, the earphone magnet 310 attracts and couples with the box magnet 200, so that a plurality of poles on the attraction face of the earphone magnet 310 and a plurality of poles on the attraction face of the box magnet 200 can attract each other together in one-to-one correspondence, to realize a multi-point positioning (at least two-point positioning) of the earphone 300 and the accommodating groove 100, so that the positioning effect between the earphone magnet 310 and the box magnet 200 is good. Moreover, the earphone magnet 310 and the box magnet 200 are the multipole magnet, to increase an attraction force between the earphone magnet 310 and the box magnet 200, so that the positioning effect between the earphone magnet 310 and the box magnet 200 is further improved.
The box magnet 200 is mounted on the box body 1001, and the earphone magnet 310 is arranged on the earphone 300. Therefore, the positioning between the earphone 300 and box body 1001 changes from the traditional single-point positioning to the multi-point positioning (at least two-point positioning) through a multi-point attraction cooperation between the earphone magnet 310 and the box magnet 200, thus increasing the positioning effect between the earphone 300 and the box body 1001, so that the earphone 300 is more stable and not easy to change its position when it is attracted on the box body 1001. Thus, the earphone 300 is more stable when charging in the box body 1001, and the charging effect is good.
The good positioning effect between the earphone 300 and the box body 1001 can avoid the charging instability of the earphone 300 caused by the gravity. Thus, a placement mode of the earphone 300 does not have to be limited to a mode of a horizontal placement and a mode of a vertical placement, so that the earphone 300 can be fixed in the accommodating groove 100 conveniently and arranged obliquely relative to the box body 1001. Since the earphone has a generally strip structure, the mode of the horizontal placement will waste more space and increase a length of the box body, the mode of the vertical placement will also waste more space and increase a height of the box body. The increase in each of the length, a width and the height of the box body will increase a volume of the box body. However, when the earphone 300 is arranged obliquely relative to the box body 1001, a space of the box body 1001 can be fully used, i.e., the space utilization rate of the box body 1001 is improved, to reduce the length or the height of the box body 1001, which is conducive to reducing the volume of the box body 1001, i.e., a volume of the earphone box 1000 becomes small and easy to carry.
Therefore, the earphone box 1000 according to the examples of the present disclosure has the advantages of the good positioning effect, the stable charging, the small volume and the good portability.
For convenience of understanding, an up-down direction of the earphone box 1000 according to the examples of the present disclosure is illustrated by an arrow Ain
As illustrated in
As illustrated in
The box cover 1002 is pivotally coupled to the box body 1001, to open and close the accommodating groove 100. That is, the box cover 1002 and the box body 1001 can rotate with each other. For example, the box body 1001 is located below the box cover 1002 in the up-down direction. A rear end of the box body 1001 is coupled to a rear end of the box cover 1002. Therefore, when a front end of the box cover 1002 rotates upward around a joint between the box cover 1002 and the box body 1001, the accommodating groove 100 can be opened and the earphone 300 can be put in or taken out. When the front end of the box cover 1002 rotates downward around the joint between the box cover 1002 and the box body 1001, the accommodating groove 100 can be closed.
The box magnet 200 is mounted on the box body 1001, and is configured as the multipole magnet. The earphone 300 is provided with the earphone magnet 310 with the same number of poles as the box magnet 200. Thus, the earphone 300 can be fixed on the box body 1001 by the multi-point positioning conveniently.
In some examples, each of the box magnet 200 and the earphone magnet 310 is the two-pole magnet. The two-pole magnet has a small volume, is convenient to mount and reduces the volume of the box body 1001. Moreover, the two-point positioning between the box magnet 200 and the earphone magnet 310 can be realized by the two-pole magnet, to improve the positioning effect between the earphone 300 and the box body 1001. In some examples, two poles on the attraction face of the earphone magnet 310 of the two-pole magnet and two poles on the attraction face of the box magnet 200 of the two-pole magnet can attract each other together correspondingly, to realize the two-point positioning effect, so that the positioning effect between the earphone magnet 310 and the box magnet 200 is good. Moreover, the earphone magnet 310 and the box magnet 200 are the two-pole magnets, to increase the attraction force between the earphone magnet 310 and the box magnet 200, so that the positioning effect between the earphone magnet 310 and the box magnet 200 is further improved. That is, the positioning effect between the earphone 300 and the box body 1001 is improved, so that the earphone 300 is more stable and not easy to change its position when it is attracted on the box body 1001. Thus, the earphone 300 is more stable when charging in the box body 1001, and the charging effect is good.
The earphone magnet 310 of the two-pole magnet and the box magnet 200 of the two-pole magnet have a strong attraction force and a good positioning effect, so that the movement and the charging instability of the earphone 300 caused by the gravity can be avoided. Thus the placement mode of the earphone 300 does not have to be limited to the mode of the horizontal placement and the mode of the vertical placement, so that the earphone 300 can be fixed in the accommodating groove 100 conveniently and arranged obliquely relative to the box body 1001.
In some examples, the accommodating groove 100 includes a left accommodating groove 110 for accommodating a left earphone and a right accommodating groove 120 for accommodating a right earphone. In some examples, the left accommodating groove 110 is located at a left portion of the box body 1001, and the right accommodating groove 120 is located at a right portion of the box body 1001. The left accommodating groove 110 and the right accommodating groove 120 are arranged symmetrically in a mirrored manner in the left-right direction, to effectively use the space of the box body 1001, improve the space utilization rate of the box body 1001, which is conducive to reducing the volume of the box body 1001, so that the earphone box 1000 has a small volume and is easy to carry.
As illustrated in
The exposed face of the first box magnet 210 can directly attract the earphone magnet 310 of the left earphone in the left accommodating groove 110 and has a plurality of positioning points (at least two), and the first box magnet 210 can be in direct contact with the earphone magnet 310 of the left earphone in the left accommodating groove 110 without a barrier layer, so that the attraction effect between the first box magnet 210 and the earphone magnet 310 of the left earphone in the left accommodating groove 110 can be improved. That is, the left earphone is fixed more stably, and the charging is stable.
Similarly, the exposed face of the second box magnet 220 can directly attract the earphone magnet 310 of the right earphone in the right accommodating groove 120 and has a plurality of positioning points (at least two), and the second box magnet 220 can be in direct contact with the earphone magnet 310 of the right earphone in the right accommodating groove 120 without the barrier layer, so that the attraction effect between the second box magnet 220 and the right earphone in the right accommodating groove 120 is improved. That is, the right earphone is fixed more stably, and the charging is stable.
As illustrated in
The first box magnet 210 is arranged on the first inclined face 111 with an outer surface 211 of the first box magnet 210 being flush with the first inclined face 111. That is, the outer surface 211 (the attraction face) of the first box magnet 210 and the first inclined face 111 are on the same plane, so that the left earphone can be placed and positioned in the left accommodating groove 110 conveniently. The second box magnet 220 is arranged on the second inclined face 121 with an outer surface 221 of the second box magnet 220 being flush with the second inclined face 121. That is, the outer surface 221 (the attraction face) of the second box magnet 220 and the second inclined face 121 are on the same plane, so that the right earphone can be placed and positioned in the right accommodating groove 120 conveniently.
In some examples, a polarity distribution of the outer surface 211 of the first box magnet 210 is different from a polarity distribution of the outer surface 221 of the second box magnet 220. For example, when an upper portion of the outer surface 211 of the first box magnet 210 is N pole and an lower portion thereof is S pole, an upper portion of the outer surface 221 of the second box magnet 220 is S pole and an lower portion thereof is N pole, or, when a left portion of the outer surface 211 of the first box magnet 210 is N pole and a right portion thereof is S pole, a left portion of the outer surface 221 of the second box magnet 220 is S pole and a right portion thereof is N pole. Thus, it is difficult to place the left earphone in the right accommodating groove 120 or to place the right earphone in the left accommodating groove 110, to facilitate the correct positioning and the placement of the left earphone and the right earphone.
As illustrated in
An axis of the left interface 131 and an axis of the right interface 132 are arranged obliquely. That is, the axis of the left interface 131 can be arranged obliquely relative to the up-down direction. For example, the axis of the left interface 131 can be substantially perpendicular to the first inclined face 111, to facilitate an electrical coupling between the left earphone and the left interface 131, i.e., to facilitate the left interface 131 to stably charge the left earphone. The axis of the right interface 132 can be arranged obliquely relative to the up-down direction, and the axis of the right interface 132 can be substantially perpendicular to the second inclined face 121, to facilitate an electrical coupling between the right earphone and the right interface 132, i.e., to facilitate the right interface 132 to stably charge the right earphone.
In some examples, an included angle between the axis of each of the left interface 131 and the right interface 132 and a horizontal plane is 45°-55°. In this angle range, the box body 1001 has a smaller volume and is easy to carry while facilitating the left interface 131/the right interface 132 to stably charge the left earphone/the right earphone.
As illustrated in
The right interface 132 is arranged on the second inclined face 121 and adjacent to the second box magnet 220. Therefore, after the right earphone enters into the right accommodating groove 120, it can be electrically coupled to the right interface 132 conveniently. Moreover, a position between the second box magnet 220 of the right earphone and the earphone magnet 310 of the right earphone has a strong attraction force, thus realizing the good positioning effect. The right interface 132 is adjacent to the second box magnet 220, so that the right earphone and the right interface 132 are coupled stably, i.e., the charging of the right earphone is more stable.
As illustrated in
In some examples, each of the first inclined face 111 and the second inclined face 121 is a frosted face. Therefore, when the left earphone is placed on the first inclined face 111, a friction is large, so that the left earphone is not easy to move and the positioning effect is good. When the right earphone is placed on the second inclined face 121, a friction is large, so that the right earphone is not easy to move and the positioning effect is good. The first box magnet 210 and the left interface 131 are arranged on the first inclined face 111 with the frosted face, so that the left earphone can be fixed and electrically coupled only by contacting the first inclined face 111. Thus, the left earphone can be arranged obliquely, maximizing utilization rate of the space of the box body 1001 and reducing the volume of the box body 1001. Moreover, the left accommodating groove 110 does not have to make profiling limit, and can realize the reliability of charging under different shapes of different specifications of ear caps. The second box magnet 220 and the right interface 132 are arranged on the second inclined face 121 with the frosted face, so that the right earphone can be fixed and electrically coupled only by contacting the second inclined face 121. Thus, the right earphone can be arranged obliquely, maximizing utilization rate of the space of the box body 1001 and reducing the volume of the box body 1001. Moreover, the right accommodating groove 120 does not have to make profiling limit, and can realize the reliability of charging under different shapes of different specifications of ear caps.

As illustrated in
In some examples, the upper mounting cavity 150 is provided with a first attraction magnet 152, the lower mounting cavity 140 is provided with a second attraction magnet 142, and the second attraction magnet 142 is configured to attract and couple with the first attraction magnet 152 when the box cover 1002 closes the accommodating groove. Thus, when the box cover 1002 is closed, a coupling between the box body 1001 and the box cover 1002 is strengthened, thus preventing the box cover 1002 from being opened by mistake and preventing the earphone 300 from being lost.
The earphone 300 according to the examples of the present disclosure includes an earphone body 310 configured as a bud shape, and the earphone body 310 is adapted to fit in the accommodating groove 100 of the earphone box 1000 according to any one of the above examples.
The earphone 300 according to the examples of the present disclosure can be obliquely placed in the accommodating groove 100 in the earphone box 1000, has a good positioning effect and can be charged stably. Moreover, after the earphone 300 is placed in the accommodating groove 100, the overall volume is small and the earphone 300 is easy to carry.
In some examples, the earphone 300 further includes a plurality of earphone sleeves 320 of different specifications. Each of the plurality of earphone sleeves 320 is adapted to be fitted over the earphone body 310, and the earphone body 310 fitted with any earphone sleeve 320 can fit in the accommodating groove 100.
That is, a space of the accommodating groove 100 is larger than a total volume of the earphone body 310 and the earphone sleeve 320 fitted over a side of the earphone body 310. The earphone 300 can be put into the accommodating groove 100 for charging and storage without removing the earphone sleeve 320. The earphone box 1000 has a strong adaptability.
