[0043] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] The embodiments of the present application are described below in combination with the accompanying drawings of the specification:

[0045] Reference Figures 1 to 10 According to the assembly structure of the embodiments of the present application, it is used for being arranged in the internal of the wireless Bluetooth earphone, for example, the assembly structure can be adapted to the ANC (Active Noise Control, active noise reduction) noise reduction earphone, sports earphone, running earphone, cycling earphone, open Bluetooth earphone, etc. The assembly structure includes a mounting bracket 100, a bearing 200 and a receiving part 300, the mounting bracket 100 is arranged in the inner cavity 410 of the shell 400 and assembled with the shell 400, in order to ensure the positioning and installation of the bearing 200 and the mounting bracket 100, the mounting bracket 100 is provided with an assembly area 110, the assembly area 110 includes a first side wall 111, a second side wall 112 and a bottom wall 113, the first side wall 111 and the second side wall 112 are connected with the bottom wall 113, and are spaced apart along the first direction, for jointly enclosing the assembly area 110 for installing the bearing 200. The bearing 200 is arranged in the assembly area 110, and the bearing 200 is connected with the first side wall 111, the second side wall 112 and the bottom wall 113, so that the bearing 200 has a determined mounting position relative to the mounting bracket 100, and the receiving part 300 is connected to the side of the bearing 200 away from the bottom wall 113, and the receiving part 300 is positioned and installed with the mounting bracket 100 through the bearing 200. Therefore, after the mounting bracket 100 is assembled with the shell 400 of the earphone, the receiving part 300 has a determined position in the shell 400, which is beneficial to improve the yield of the earphone.

[0046] In addition, the connection mode of the bearing 200 and the first side wall 111, the second side wall 112 and the bottom wall 113 can be adhesion by glue or double-sided adhesive tape. When the glue is not dry, the bearing 200 is easily pulled and offset in the assembly area 110. Therefore, the mounting bracket 100 is further provided with a positioning portion 120 connected with the bottom wall 113. The bearing 200 is provided with a positioning hole 210, and the positioning portion 120 is arranged in the positioning hole 210 to limit the movement of the bearing 200 relative to the mounting bracket 100. In addition, the bearing 200 and the mounting bracket 100 can be aligned and mounted, and the installation deviation can be effectively avoided. The sound receiving part 300 is connected to the side of the bearing 200 away from the bottom wall 113, which can avoid interference with the assembly of the bearing 200 and the mounting bracket 100. Thus, through the cooperation of the positioning portion 120 and the positioning hole 210, the bearing 200 and the mounting bracket 100 can be positioned and mounted, and the position offset of the bearing 200 relative to the mounting bracket 100 can be limited after assembly. It should be understood that the sound receiving part 300 is connected to the bearing 200, and the positioning and mounting of the bearing 200 and the mounting bracket 100 is the positioning and mounting of the sound receiving part 300, which is beneficial to ensure the consistency of the installation position of the sound receiving part 300 and improve the yield of the earphone.

[0047] Specifically, referring to Figure 1 and Figure 2 , the shell 400 has an inner cavity 410, and the cavity wall of the inner cavity 410 is provided with a groove for inserting the bearing 200. The sound receiving part 300 is connected to the bearing 200, and the bearing 200 is inserted into the groove to realize the installation and fixation of the bearing 200 and the sound receiving part 300 relative to the shell 400. However, the space of the inner cavity 410 is narrow, and there is a problem that the bearing 200 is not inserted to the bottom of the groove. In addition, after the bearing 200 is inserted into the groove, it needs to be adhesion by glue. When the glue is not dry, the bearing 200 is easily pulled and the position is changed. When the earphone is produced, it is difficult to ensure the consistency of the position of the bearing 200 and the sound receiving part 300 in the inner cavity 410.

[0048] Therefore, referring to Figures 3 to 9The mounting bracket 100 is additionally arranged in the application, and the outer wall profile of the mounting bracket 100 can be the same as the inner wall profile of the shell 400, so as to ensure the positioning assembly of the mounting bracket 100 and the shell 400. The sound receiving piece 300 is connected to the bearing piece 200, the bearing piece 200 is arranged in the assembly area 110, and the positioning part 120 is matched with the positioning hole 210. Therefore, the bearing piece 200 can be positioned and mounted with the shell 400 through the mounting bracket 100. When the bearing piece 200 has a certain relative position with the mounting bracket 100, the sound receiving piece 300 also has a certain mounting position with the mounting bracket 100, so as to realize the positioning and mounting of the sound receiving piece 300 in the inner cavity 410 and limit the movement of the sound receiving piece 300 in the inner cavity 410, thereby reducing the number of defective products caused by the difference in mounting position and improving the production efficiency of the earphone.

[0049] It should be noted that the bearing piece 200 can be a PCB (Printed Circuit Board), which is used to provide mechanical support and electrical connection for the sound receiving piece 300. The sound receiving piece 300 can be an FB Mic (Feedback Microphone), the positioning part 120 can be a cylindrical structure, and the positioning hole 210 can be a circular hole matched with the cylindrical structure. When the bearing piece 200 is assembled with the mounting bracket 100, the positioning hole 210 is aligned and mounted with the positioning part 120.

[0050] Reference Figures 3 to 9 In some embodiments, along the first direction, the positioning part 120 is located at the connection between the bottom wall 113 and the first side wall 111. The side of the bearing piece 200 close to the first side wall 111 is provided with the positioning hole 210, and the positioning hole 210 is provided with a mounting gap facing the first side wall 111, so as to facilitate the assembly of the positioning part 120 and the positioning hole 210. When the bearing piece 200 is assembled with the mounting bracket 100, the positioning part 120 can enter the positioning hole 210 through the mounting gap. The cooperation between the positioning hole 210 and the positioning part 120 is used to ensure that the bearing piece 200 is installed in place. In the assembly area 110, the first side wall 111 and the second side wall 112 are used to limit the movement of the bearing piece 200 along the first direction, and the cooperation between the positioning part 120 and the positioning hole 210 is used to limit the movement of the bearing piece 200 along the second direction, which is perpendicular to the first direction.

[0051] Alternatively, along the first direction, the positioning part 120 is located at the connection between the bottom wall 113 and the second side wall 112. The side of the bearing piece 200 close to the second side wall 112 is provided with the positioning hole 210, and the positioning hole 210 is provided with a mounting gap facing the second side wall 112. The positioning part 120 can enter the positioning hole 210 through the mounting gap.

[0052] Reference Figures 3 to 9In some embodiments, the mounting bracket 100 comprises two positioning portions 120 along the first direction, one of which is located at the connection between the bottom wall 113 and the first side wall 111, and the other is connected to the connection between the bottom wall 113 and the second side wall 112. Correspondingly, the carrier 200 is provided with two positioning holes 210 along the first direction, which are respectively located on the opposite sides of the carrier 200, and the two positioning holes 210 correspond one-to-one to the positions of the two positioning portions 120. The two positioning holes 210 are each provided with a mounting gap, and the two positioning portions 120 can enter the different positioning holes 210 through the mounting gaps. Through the combination of the two sets of positioning holes 210 and the positioning portions 120, it is beneficial to avoid the carrier 200 from shaking in the assembly area 110, and to improve the installation position accuracy of the carrier 200.

[0053] Specifically, along the first direction, the carrier 200 comprises a third side wall 220 and a fourth side wall 230 arranged oppositely, the third side wall 220 is located on the side facing the first side wall 111, and the fourth side wall 230 is located on the side facing the second side wall 112. The third side wall 220 and the fourth side wall 230 are each provided with a positioning hole 210. In the assembly area 110, the two positioning holes 210 are assembled one-to-one with the two positioning portions 120, and the third side wall 220 abuts against the first side wall 111, and the fourth side wall 230 abuts against the second side wall 112, which is beneficial to further improve the stability of the assembly of the carrier 200, and in turn the assembly of the receiver 300 is also more stable.

[0054] It should be noted that the mounting gap can make the positioning hole 210 have a semicircular hole shape, and correspondingly, the positioning portion 120 at least comprises a semicircular cylindrical shape matched with the positioning hole 210.

[0055] Reference Figures 3 to 9 In some embodiments, after the assembly structure is assembled, it is necessary to ensure that the receiver 300 is located on the side of the carrier 200 away from the bottom wall 113, and the shell 400 comprises a sound emitting hole 420, and the side of the carrier 200 away from the sound emitting hole 420 also needs to be connected with an FPC (Flexible Printed Circuit). Therefore, the carrier 200 needs to have a specific assembly posture relative to the mounting bracket 100. Based on this, the mounting bracket 100 comprises two positioning portions 120 along the first direction, one of which is located at the connection between the bottom wall 113 and the first side wall 111, and the other is located at the connection between the bottom wall 113 and the second side wall 112. Along the first direction, the projections of the two positioning portions 120 on the surfaces of the first side wall 111 or the second side wall 112 are arranged along the second direction, and the second direction is perpendicular to the first direction.

[0056] Similarly, in order to ensure the cooperation and installation with the two positioning parts 120, the carrier 200 is also provided with two positioning holes 210, and the positions of the two positioning holes 210 are one-to-one corresponding to the positions of the two positioning parts 120, that is, along the first direction, the carrier 200 includes opposite third and fourth side walls 220 and 230, and the third and fourth side walls 220 and 230 are both provided with positioning holes 210, and along the first direction, the projections of the two positioning holes 210 on the surface of the third or fourth side wall 220 or 230 are spaced apart along the second direction, and the spacing of the projections of the two positioning holes 210 is equal to the spacing of the projections of the two positioning parts 120, so that the two positioning parts 120 and the two positioning holes 210 are one-to-one corresponding. Through the cooperation of the two positioning parts 120 and the two positioning holes 210, the carrier 200 can be assembled with the mounting bracket 100 in a determined posture, avoiding the deviation of the assembly position of the carrier 200 from the design position, which is beneficial to improve the production efficiency of the earphone.

[0057] Reference Figures 3 to 9 In some embodiments, along the first direction, the mounting bracket 100 includes a first side wall 111 and a second side wall 112, and the carrier 200 includes a third side wall 220 and a fourth side wall 230, and the carrier 200 is arranged in the assembly area 110. In the assembly area 110, when the size of the positioning hole 210 is insufficient, the cooperation of the positioning hole 210 and the positioning part 120 will affect the installation stability of the carrier 200, and will also cause a gap between the first side wall 111 and the third side wall 220 and / or between the second side wall 112 and the fourth side wall 230. Therefore, the positioning hole 210 further includes an arc wall 211 with a reference point as the center, wherein the reference point to the arc wall 211 is defined as a reference circle with a radius, and the ratio of the cross-sectional area of the positioning hole 210 to the area of the reference circle is greater than 0.5, that is, the cross-sectional area of the positioning hole 210 accounts for more than half of the area of the reference circle, so that along the first direction, the positioning part 120 can be placed more in the positioning hole 210, and when the positioning part 120 is placed in the positioning hole 210, the third side wall 220 abuts against the first side wall 111, and the fourth side wall 230 abuts against the second side wall 112, which is beneficial to improve the stability of the assembly of the carrier 200, that is, the assembly of the receiver 300 is also more stable.

[0058] In addition, after the positioning part 120 is placed in the positioning hole 210, the positioning part 120 and the hole wall of the positioning hole 210 can also be bonded by glue or double-sided tape, further increasing the stability of the connection between the carrier 200 and the mounting bracket 100.

[0059] It should be noted that the cross-sectional area of the positioning hole 210 is understood as the cross-sectional area of the positioning hole 210 when viewed along a plane perpendicular to the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The shape of the positioning hole 210 can be a partial curved section of a cylindrical hole, which ensures that the positioning hole 210 accommodates a portion of the positioning portion 120 along the first direction, and the proportion of the cross-sectional area of the positioning portion 120 is more than 50%. In addition, the shape of the positioning hole 210 can also be square, triangular, trapezoidal, etc., and the outer wall shape of the positioning portion 120 is the same as the shape of the inner wall of the positioning hole 210, which ensures the assembly fit between the positioning portion 120 and the positioning hole 210. When the positioning portion 120 is located in the positioning hole 210, the third side wall 220 abuts against the first side wall 111, and the fourth side wall 230 abuts against the second side wall 112, thereby ensuring the stability of the carrier 200 and the mounting bracket 100.

[0060] Reference Figures 3 to 9 In some embodiments, the mounting bracket 100 includes a plurality of positioning portions 120, and the carrier 200 includes a plurality of positioning holes 210. The number of positioning portions 120 is equal to the number of positioning holes 210, and each positioning portion 120 is correspondingly arranged in each positioning hole 210. For example, along the first direction, the plurality of positioning portions 120 are located at the connection between the bottom wall 113 and the first side wall 111, and / or the plurality of positioning portions 120 are located at the connection between the bottom wall 113 and the second side wall 112. The number of positioning portions 120 can be two or three, and the number and position of the positioning holes 210 correspond to the number and position of the positioning portions 120. Through the one-to-one fit between the plurality of positioning holes 210 and the plurality of positioning portions 120, the shaking of the carrier 200 relative to the mounting bracket 100 is reduced, and the installation accuracy of the carrier 200 is improved.

[0061] Reference Figures 3 to 10 In some embodiments, in order to avoid the mounting bracket 100 and the shell 400 from blocking the sound passage of the earphone, the mounting bracket 100 is further provided with a avoiding through hole 130. The avoiding through hole 130 penetrates through the mounting bracket 100 along the second direction, and the second direction is perpendicular to the first direction. A loudspeaker is arranged in the inner cavity 410 of the earphone, and the sound emitted by the loudspeaker can be transmitted outward through the avoiding through hole 130. In addition, the assembly area 110 is arranged on the outer hole wall of the avoiding through hole 130, and the receiver 300 is located on the side of the carrier 200 away from the avoiding through hole 130, so as to avoid occupying the space of the avoiding through hole 130 and ensure that the sound is transmitted outward smoothly.

[0062] Specifically, the shell 400 is provided with an inner cavity 410 and a sound emitting hole 420, the mounting bracket 100 is arranged in the inner cavity 410 close to the sound emitting hole 420, and the opening of the avoiding through hole 130 faces the sound emitting hole 420. The sound emitting hole 420 is connected with the inner cavity 410 through the avoiding through hole 130, so that the sound emitted by the loudspeaker in the inner cavity 410 can be more smoothly transmitted outward. The carrier 200 is arranged in the assembly area 110, and the assembly area 110 is arranged outside the hole wall of the avoiding through hole 130. The sound receiving part 300 is located on the side of the carrier 200 away from the avoiding through hole 130. Therefore, on the basis of ensuring the positioning and installation of the carrier 200 and the sound receiving part 300, the space of the avoiding through hole 130 can also be avoided, and the sound conduction is ensured.

[0063] Reference Figures 3 to 8 In some embodiments, in order to make the sound transmission of the earphone more smooth, the mounting bracket 100 is also provided with an avoiding space 140. The assembly area 110 is connected with the avoiding through hole 130 through the avoiding space 140. The avoiding space 140 separates the bottom wall 113 into independent first and second parts 1131 and 1132. The first and second parts 1131 and 1132 are connected to the side of the carrier 200 away from the sound receiving part 300. Therefore, the space for sound transmission is composed of the avoiding through hole 130 and the avoiding space 140, which further expands the sound transmission channel and is beneficial to improve the sound transmission effect of the earphone. In addition, the first and second parts 1131 and 1132 can be slightly deformed and moved away from each other along the first direction due to the arrangement of the avoiding space 140. Therefore, the first and second side walls 111 and 112, the first and second parts 1131 and 1132, and the positioning part 120 can be slightly moved along the first direction within a certain range to realize the fine adjustment of the position. When the carrier 200 is assembled, the assembly of the carrier 200 is more convenient.

[0064] Reference Figures 3 to 9 In some embodiments, along the second direction, the mounting bracket 100 is also provided with a first protruding part 150. Along the third direction, the first protruding part 150 is arranged in a spaced manner with the carrier 200. The first, second, and third directions are perpendicular to each other. The first protruding part 150 is used to combine with the protrusion inside the earphone shell 400 to form a mounting part. The mounting part can be used to mount the earphone components such as the loudspeaker, so as to realize the installation of the mounting bracket 100 while avoiding affecting the layout and installation of other components in the earphone.

[0065] For example, the inside of the shell 400 is provided with a circular arc protrusion for positioning and mounting the loudspeaker. The shape of the first protruding part 150 can be a segment of the circular arc protrusion, which is used to avoid interference with the installation of the loudspeaker and ensure the positioning and installation of the loudspeaker by the shell 400. Therefore, it is beneficial to fully utilize the internal space of the earphone, and the structure of the earphone as a whole is more compact.

[0066] It should be noted that the shape of the first protruding portion 150 can be adjusted according to the internal structure of the earphone.

[0067] With reference to Figures 3 to 7 In some embodiments, the mounting bracket 100 is further provided with a second protruding portion 160 in the second direction, and the second protruding portion 160 is located on the side of the mounting bracket 100 provided with the first side wall 111 or the second side wall 112 in the first direction, the second direction is perpendicular to the first direction, and the second protruding portion 160 is used to provide a reference for the assembly of the mounting bracket 100 and the shell 400, thereby saving the trial and error time when the two are assembled. For example, the shell 400 is provided with a sound receiving port, and when the mounting bracket 100 and the shell 400 are assembled, the second protruding portion 160 can be assembled by referring to the position of the sound receiving port as a reference. In the first direction, if the second protruding portion 160 is located on the side close to the sound receiving port, the two can be assembled, which is convenient for distinguishing that the mounting bracket 100 is adapted to be assembled with one of the left and right earphones, and is beneficial to improve the assembly efficiency of the earphone.

[0068] With reference to Figures 1 to 10 According to the earphone provided in the embodiments of the present application, the earphone comprises the shell 400 and the assembly structure in any of the above embodiments, the shell 400 has an inner cavity 410, and the assembly structure is arranged in the inner cavity 410. In any of the above embodiments, the assembly structure comprises the mounting bracket 100, the bearing 200 and the sound receiving member 300, and the mounting bracket 100, the bearing 200 and the sound receiving member 300 have a determined relative position after assembly. Therefore, only the mounting bracket 100 needs to be positioned and mounted in the inner cavity 410, and the positions of the bearing 200 and the sound receiving member 300 in the inner cavity 410 can be determined. Compared with the method of opening a groove in the shell 400, the assembly position of the sound receiving member 300 in the shell 400 is more consistent, and thus the sound quality of the left and right earphones is more consistent.

[0069] Specifically, the earphone of the embodiment of the application comprises a mounting bracket 100, an FB Mic, a PCB, an FPC and a shell 400, the FB Mic is attached to the PCB, the FPC is connected to the PCB, and a noise reduction control system is further integrated in the earphone, the FB Mic is used to receive environmental noise, residual noise after noise reduction processing of the earphone, and sound in the ear when the earphone plays audio, etc., the noise reduction control system reduces noise according to the sound received by the FB Mic, the FB Mic is connected to the PCB, the position of the FB Mic and the PCB is limited below the mounting bracket 100, so that the FPC does not cause the position of the PCB to deviate, therefore, the FB Mic has better position consistency, so that the earphone has better frequency response consistency and sound stability, and the path, reflection, absorption, etc. of sound in the propagation process are highly similar, and therefore, the sound emitted by each earphone can remain stable in tone, pitch and volume, and the sound difference between the left and right ears is not large, so that the user has a better auditory experience. In addition, the good position consistency of the FB Mic assembly can also reduce the generation of defective products caused by assembly position difference, thereby reducing production cost and improving production efficiency.

[0070] The above describes the embodiments of the application in detail in combination with the drawings, but the application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the art without departing from the purpose of the application. In addition, the embodiments of the application and the features in the embodiments can be combined with each other without conflict.
