[0043] In this embodiment, the sound generating module 10 and the support 20 are detachably connected through the fixing portion 22 and the elastic clamping piece 30, so that the sound generating module 10 can be assembled on the support 20 during use, and the sound generating module 10 can be used in cooperation with the support 20, preventing the sound generating module 10 from accidentally falling during use, and improving the safety and stability of use.

Maintenance personnel can easily disassemble and install the sound generating module 10, quickly locate and solve problems, thereby improving the maintenance efficiency and reducing the maintenance cost.

[0045] The components in the earphone unit 100 will be described in detail below.

[0046] Please refer to Figure 2 , Figure 5 and Figure 6 , the sound generating module 10 includes a housing 11, which can have multiple cavities inside, which can be used to install a circuit board 13 and sound generating units, batteries and other necessary or unnecessary electronic components 14 electrically connected to the circuit board 13. This embodiment does not make a detailed description, and the housing 11 can provide protection for the internal circuit board 13 and electronic components 14. Adjacent cavities can be connected to each other to facilitate signal transmission or energy flow between electronic components; adjacent cavities can also be separated by a partition to improve the independence between different electronic components and reduce mutual interference.

[0047] The housing 11 can be made of metal or non-metal materials, such as aluminum alloy, titanium alloy, stainless steel, plastic, silica gel, ceramic, etc., which is not limited in this embodiment.

[0048] The housing 11 includes a bottom plate 111 and a top cover 112 opposite in the Z direction, and a side plate 113 extending in a ring structure along the edge of the bottom plate 111, the bottom plate 111, the side plate 113 and the top cover 112 together enclose a space to form multiple cavities, and a mounting side 114 can be formed on any one of the bottom plate 111, the top cover 112 and the side plate 113.

[0049] Please refer to Figure 5The following takes the side plate 113 as an example to illustrate the installation side 114.

[0050] The bottom plate 111 is provided with a sound hole 1111, which is located opposite to the sound outlet side of the sound emitting unit, so as to ensure that the sound can be directly and efficiently transmitted to the ear canal of the user, thereby improving the clarity and fidelity of the sound. In order to improve the clarity of the sound, the sound hole 1111 needs to be close to the ear canal. In order to avoid unnecessary interference of the installation side 114 connected to the support 20 to the user or the wearing structure, the installation side 114 can be designed on the part of the side plate 113 away from the sound hole 1111, which can leave sufficient wearing space for the user, thereby improving the comfort and stability of wearing.

[0051] Please refer to Figure 4 and Figure 5 The shell 11 is provided with a mounting cavity 115, which is arranged close to the installation side 114, so as to reduce the distance that the fixing part 22 needs to be inserted. The mounting cavity 115 can extend along the first direction or along the edge track of the installation side 114, as long as the mounting cavity 115 has sufficient space to meet the movement of the elastic clamping piece 30 along the first direction. The first direction is the X direction in Figure 3 .

[0052] The installation side 114 is provided with a dismounting opening 116 which is in communication with the mounting cavity 115. The shape and size of the dismounting opening 116 should match the projection shape and size of the fixing part 22 along the Y direction. The fixing part 22 can be inserted into the mounting cavity 115 through the channel 118, which helps to reduce the friction and resistance in the process of assembly and disassembly, and also ensures that the fixing part 22 can be accurately positioned in the mounting cavity 115, thereby realizing the stable connection between the sound emitting module 10 and the support 20.

[0053] The shape of the dismounting opening 116 can be a regular or irregular shape such as a rectangle, a trapezoid, a circle, a semicircle, etc. The present embodiment does not limit this.

[0054] The orientation of the dismounting opening 116 is arranged along the second direction, and the second direction is arranged at an angle with the first direction. The installation side 114 can be a plane or an arc surface. In the case of the installation side 114 being a plane, the first direction is the extension direction of the plane, and the second direction is perpendicular to the first direction. In the case of the installation side 114 being an arc surface, the second direction is the normal direction of the position of the installation opening. The second direction can be perpendicular to the first direction or have a certain angle, for example, 30°, 45°, 60°, etc.

[0055] It should be noted that the insertion direction of the fixing part 22 and the orientation of the dismounting opening 116 do not require complete consistency.

[0056] The first direction and the second direction referred to herein, in some examples, can be perpendicular, for example, the first direction is the X direction in Figure 3 , and the second direction is the Y direction in Figure 3 . This embodiment is described as an example.

[0057] Please refer to Figure 2 and Figure 4 , the mounting side 114 can be provided with a limiting groove 1131 with a certain depth, and in the case of elastic clamping piece 30 and fixed part 22 clamping, the connecting part 21 and the bottom wall of the limiting groove 1131 are in close contact, which can limit the extension distance of the fixed part 22, and through the cooperation of the elastic clamping piece 30 and the fixed part 22, the complete limiting of the fixed part 22 is realized, preventing the elastic clamping piece 30 and the fixed part 22 from loosening in the clamping state.

[0058] The mounting cavity 115 has a first wall surface 1151 and a second wall surface 1152 arranged opposite along the X direction, wherein the second wall surface 1152 is connected with the edge of the dismounting opening 116, and in the case of the fixed part 22 extending into the mounting cavity 115, the fixed part 22 can be in close contact with the second wall surface 1152, which can limit the displacement of the fixed part 22 along the X direction, thereby improving the connection stability when the elastic clamping piece 30 and the fixed part 22 are clamped. A certain gap can also be formed between the fixed part 22 and the second wall surface 1152, as long as the size of the gap along the X direction is smaller than the clamping depth of the elastic clamping piece 30 and the fixed part 22.

[0059] Please refer to Figure 4 , Figure 6 and Figure 7 , the mounting cavity 115 is also provided with a limiting step 117, when the elastic clamping piece 30 and the fixed part 22 are clamped, the elastic clamping piece 30 will be in contact with and stopped by the limiting step 117, at this time the elastic clamping piece 30 reaches the first position, which can improve the firmness and stability of the clamping between the elastic clamping piece 30 and the fixed part 22. In the case of separating the support 20 and the sound generating module 10, the limiting step 117 can limit the further movement of the elastic clamping piece 30, preventing it from being pulled out or unnecessarily abutting against the second wall surface 1152 due to the loss of support from the fixed part 22. This design not only protects the elastic clamping piece 30 from damage, but also ensures that the sound generating module 10 can maintain the integrity of the structure during disassembly.

[0060] The stroke of the elastic clamping piece 30 to the first position can be smaller than the stroke of the elastic clamping piece 30 to the limiting step 117, so that the elastic clamping piece 30 can reach a stable state earlier during clamping, thereby improving the assembly efficiency, and the elastic clamping piece 30 can provide a resisting force along the X direction to the fixed part 22.

[0061] Please continue to refer to Figure 4 , Figure 6 and Figure 7 The top of the shell 11 has an opening 1155, and the elastic clamping piece 30 can be loaded into the mounting cavity 115 from the opening 1155, which reduces the assembly difficulty of the elastic clamping piece 30 and the shell 11. The sound generating module 10 further comprises a cover plate 12, which is arranged at the opening 1155 and serves to close the mounting cavity 115.

[0062] In some embodiments, one end of the cover plate 12 is connected to the shell 11, and the other end extends into the mounting cavity 115 and is bent at the end inside the mounting cavity 115 to form a limiting step 117. Thus, other step structures are avoided in the entire stroke of the elastic clamping piece 30 between the first position and the second position, and the smoothness of the movement of the elastic clamping piece 30 is improved.

[0063] Based on the above structure, after the elastic clamping piece 30 is loaded into the mounting cavity 115, the end of the cover plate 12 forming the limiting step 117 can be first extended into the mounting cavity 115. In order to clearly define the extension distance of the limiting step 117, the top wall of the mounting cavity 115 is provided with a mounting position, and after the limiting step 117 is moved to the mounting position, the other end of the cover plate 12 can be fixed to the shell 11 by a fastener.

[0064] Please continue to refer to Figure 4 , Figure 6 and Figure 7 The mounting cavity 115 can be divided into an active space 1153 and a disassembly slot 1154 by taking the edge of the disassembly opening 116 as a boundary line, the inner wall surface of the active space 1153 away from the disassembly slot 1154 is a first wall surface 1151, the slot wall of the disassembly slot 1154 opposite to the first wall surface 1151 along a first direction is a second wall surface 1152, and the slot opening of the disassembly slot 1154 is the disassembly opening 116. When the elastic clamping piece 30 is in the first position, the elastic clamping piece 30 at least partially extends into the disassembly slot 1154, which facilitates the clamping of the elastic clamping piece 30 and the fixed part 22 extending into the disassembly slot 1154.

[0065] The limiting step 117 can be located in the active space 1153 or in the disassembly slot 1154, and the specific position of the limiting step 117 is determined according to the stroke requirement of the elastic clamping piece 30.

[0066] Please refer to Figure 4 and Figure 8The elastic clamping piece 30 comprises an elastic piece 31 and a clamping block 32. The clamping block 32 is located between the first wall surface 1151 and the second wall surface 1152, and the elastic piece 31 is abutted between the first wall surface 1151 and the clamping block 32. When the elastic clamping piece 30 is located at the first position, the elastic piece 31 is in a pre-tightening state or a natural state. During the process that the fixing portion 22 extends into the disassembly groove 1154, the clamping block 32 is pushed so as to deform the elastic piece 31 until the fixing portion 22 is completely extended into the disassembly groove 1154. At this time, the clamping block 32 is moved along the X direction under the elastic restoring force of the elastic piece 31 until the clamping block 32 is clamped with the fixing portion 22. The whole assembling process of the support 20 and the sound production module 10 does not need to rely on tools, which reduces the complexity and cost of assembly, and improves the efficiency and convenience of assembly.

[0067] When it is needed to separate the support 20 and the sound production module 10, the clamping block 32 can be pushed by external force so as to deform the elastic piece 31. After the clamping block 32 is separated from the fixing groove, the fixing portion 22 can be conveniently taken out from the disassembly groove 1154.

[0068] In some embodiments, the elastic piece 31 can be a spring, a spring sheet, an air spring or the like. In other embodiments, the elastic piece 31 can also be a magnetic piece, for example, two magnet sheets. The present embodiment does not limit the specific structure of the elastic piece 31, but only needs to ensure that the elastic piece 31 can provide an acting force in the first direction to the clamping block 32 when the elastic clamping piece 30 is located at the second position.

[0069] Please refer to Figure 4 , Figure 6 and Figure 8 . The side of the clamping block 32, which faces the second wall surface 1152, is provided with an anti-disengagement portion 321. When the elastic clamping piece 30 is located at the first position, the anti-disengagement portion 321 extends into the disassembly groove 1154 and is clamped with the fixing portion 22. When the elastic clamping piece 30 is located at the second position, the anti-disengagement portion 321 is separated from the fixing portion 22.

[0070] The side of the anti-disengagement portion 321, which faces the disassembly opening 116, is provided with a guide surface 3211. During the process that the fixing portion 22 extends into the disassembly groove 1154, the guide surface 3211 is contacted with the fixing portion 22, so as to push the whole clamping block 32 to compress the spring. The guide surface 3211 can be an arc surface or an inclined surface. During the process that the fixing portion 22 extends into the disassembly groove 1154, the guide surface 3211 is contacted with the fixing portion 22, so that the acting force has a reverse component force in the X direction, thereby pushing the clamping block 32 to move reversely along the X direction.

[0071] Please refer to Figure 4 , Figure 6 and Figure 8The clamping block 32 has a limiting surface 322 opposite to the second wall surface 1152. The limiting surface 322 can be provided on any side of the clamping block 32, and the side of the limiting surface 322 facing the second wall surface 1152 can be used as the limiting surface 322. Alternatively, the outer side of the clamping block 32 can be used as the limiting surface 322. When the clamping block 32 moves along the X direction, the limiting step 117 is located on the moving track of the clamping block 32. In the case that the fixed part 22 is not inserted into the dismounting groove 1154, the limiting surface 322 can be stopped on the limiting step 117 to limit the stroke of the clamping block 32, thereby avoiding the risk that the clamping block 32 directly contacts the second wall surface 1152 or the clamping block 32 is pulled out of the dismounting opening 116.

[0072] In other embodiments, the clamping block 32 can also be limited in other ways, for example, a slot is formed on the clamping block 32, the inner wall of the installation cavity 115 is connected with a limiting clamping plate, the limiting clamping plate extends into the slot and cooperates with the slot wall to achieve limiting. This embodiment does not limit this.

[0073] Please refer to Figure 4 , Figure 6 and Figure 8 The clamping block 32 has a force receiving surface 323 opposite to the second wall surface 1152. The force receiving surface 323 can bear the force during dismounting to move the clamping block 32 in the reverse direction along the X direction until the clamping block 32 is separated from the fixed part 22. Similarly, the force receiving structure can be provided on any side of the clamping block 32, and the side of the force receiving structure facing the second wall surface 1152 can be used as the force receiving surface 323. Alternatively, the outer side of the clamping block 32 can bear the force during dismounting to form the force receiving surface 323.

[0074] The dismounting of the support 20 and the sound generating module 10 can be achieved by using a needle-like structure such as a clamping needle. The needle-like structure such as the clamping needle has an elongated shape and a sharp head, which is convenient to penetrate into the channel 118 and push the clamping block 32. Specifically, the shell 11 has a channel 118 communicating with the installation cavity 115, the channel 118 extends from the second wall surface 1152 along the first direction and penetrates through the shell 11, and the channel 118 is opposite to the force receiving surface 323. The clamping needle can penetrate through the channel 118, and the clamping needle continues to move in the reverse direction along the X direction to abut against the force receiving surface 323 and push the clamping block 32 to move.

[0075] The force receiving surface 323 can be arranged adjacent to the anti-disengagement block along the Z direction, and there should be no obstruction between the force receiving surface 323 and the second wall surface 1152. This ensures that the clamping needle can smoothly penetrate through the channel 118 and act on the force receiving surface 323 without any obstruction, thereby improving the smoothness and accuracy of the dismounting process.

[0076] The limiting surface 322 and the force receiving surface 323 can be arranged in the same plane, as shown in Figure 8As shown, the limiting surface 322 and the force receiving surface 323 are located on the same plane, but each bears a different functional area. For example, the upper half can be used for limiting to ensure that the clamping block 32 does not exceed the predetermined range during movement; and the lower half is used to contact the clamping pin and transmit the acting force to achieve the disassembly function. The upper half and the lower half in the embodiment are not strictly divided according to the center line, and the upper half and the lower half are not necessarily continuous. In other embodiments, the limiting surface 322 and the force receiving surface 323 can also be realized by different structures, and the embodiment does not limit this.

[0077] The clamping block 32 can be designed as an integral structure without additional connecting structures or components. Since different parts of the clamping block 32 need to bear acting forces in different directions, such as the limiting stop force, the clamping state resisting force, the disassembly pushing force, the acting force of the elastic member 31, etc., the integral structure can improve the stability and reliability of the clamping block 32, and also facilitates manufacturing and processing, thereby reducing production costs.

[0078] In other embodiments, the support 20 and the sound production module 10 can also use other disassembly methods, for example, a guide groove is provided on the shell 11 and communicates with the mounting cavity 115, a push rod is protruded on the clamping block 32, the push rod extends along the Z direction and passes through the guide groove, and the extension direction of the guide groove is consistent with the movement track of the clamping block 32. By pushing the push rod, the clamping block 32 can be separated from the fixed part 22. In order to prevent misoperation, a rotatable protective cover can be provided on the shell 11, which can shield the push rod to prevent misoperation, or the push rod can be exposed by rotating the protective cover.

[0079] Please refer to Figure 4 , Figure 6 and Figure 8 , a limiting notch 324 is provided at one end of the clamping block 32 facing the first wall surface 1151, that is, the limiting notch 324 and the anti-dropping block are arranged on the opposite sides of the clamping block 32. The end of the elastic member 31 away from the first wall surface 1151 is limited in the limiting notch 324, and when the elastic member 31 is deformed, it can limit the elastic member 31, control the deformation direction of the elastic member 31 along the X direction, and thus provide a stable pushing force for the clamping block 32.

[0080] The limiting notch 324 can be located at the edge, in which case the wall surface of the limiting notch 324 and the inner wall surface of the movable space 1153 jointly limit the elastic member 31; the limiting notch 324 can also be located in the middle, in which case the limiting notch 324 is a counterbore structure. The embodiment does not limit this.

[0081] Please refer to Figures 1 to 3The support 20 comprises a connecting portion 21 and a fixing portion 22, and the extending direction of the connecting portion 21 matches the contour of the mounting side 114. When the mounting side 114 is a plane, the connecting portion 21 is designed to be flat, and the connecting portion 21 is limited in the limiting groove 1131 of the mounting side 114, so as to determine the position of the fixing portion 22 in the Z direction; the connecting portion 21 is attached to the bottom wall of the limiting groove 1131, so as to determine the Y direction position of the fixing portion 22; meanwhile, the fixing portion 22 extends into the dismounting groove 1154 and is clamped with the clamping block 32 of the elastic clamping piece 30, so as to determine the position of the fixing portion 22 in the X direction. Thus, the position of the fixing portion 22 is unique when the fixing portion 22 is clamped with the elastic clamping piece 30, so as to ensure the consistency of the assembled state of the support 20 and the sound production module 10. Moreover, the structure can be prevented from loosening, and better bear the force and vibration from all directions.

[0082] Please refer to Figures 2 to 4 The fixing portion 22 is provided with a clamping groove 221, the fixing portion 22 extends into the dismounting groove 1154, the anti-dropping block is clamped into the clamping groove 221, so as to realize the clamping of the elastic clamping piece 30 and the fixing portion 22. The clamping block 32 moves in the X direction under the action of external force, so that the anti-dropping block is separated from the clamping groove 221, and the clamping of the elastic clamping piece 30 and the fixing portion 22 is released.

[0083] It can be understood that when the limiting groove 1131 does not exist in the mounting side 114, the connecting portion 21 can be attached to the side wall of the shell 11 where the mounting side 114 is located, and the shell 11 should be provided with a limiting piece to limit the displacement of the fixing portion 22 in the X direction.

[0084] Further, the limiting groove 1131 has a certain extension distance, that is, the extending part of the limiting groove 1131 can cover the dismounting opening 116 and the channel 118, that is, the opening 1155 formed by the dismounting opening 116 and the channel 118 on the shell 11 can be located on the bottom wall of the limiting groove 1131. In the state that the connecting portion 21 is attached to the bottom wall of the limiting groove 1131, the connecting portion 21 can cover the dismounting opening 116 and the channel 118, so as to avoid the opening 1155 formed by the dismounting opening 116 and the channel 118 on the shell 11 directly exposed to the outside, improve the integrity of the appearance of the earphone unit 100, and play a dustproof role.

[0085] Since the connecting portion 21 covers the channel 118, the connecting portion 21 can be provided with a through hole 211 communicated with the channel 118, so as to facilitate the needle-shaped structure such as a clamping needle to pass through and enter the channel 118. In some embodiments, the support 20 further comprises a plugging head 23, and the plugging head 23 is detachably arranged in the through hole 211. In the case of dismounting the support 20 and the sound production module 10, the plugging head 23 can be taken out from the through hole 211. In the case that the support 20 and the sound production module 10 are combined together for use, the plugging head 23 is clamped into the through hole 211, so as to play a dustproof role and prevent the through hole 211 or the channel 118 from being blocked.

[0086] As Figures 1 to 3 , based on the above embodiments, in some embodiments, the mounting side 114 of the shell 11 can also be provided with a mounting groove 119, and the mounting groove 119 is provided with a fixing column 40. The support 20 can also include a bearing portion 24 provided on the connecting portion 21, and the bearing portion 24 is arranged in the extension direction of the connecting portion 21 and spaced apart from the fixing portion 22. The bearing portion 24 extends into the mounting groove 119 and abuts against the side wall of the fixing column 40. In this embodiment, the sound generating module 10 and the support 20 have two connection points. The first connection point is composed of the fixing column 40 and the bearing portion 24, and the second connection point is composed of the elastic clamping piece 30 and the fixing portion 22. The double connection point design can improve the stability of the support 20 and the sound generating module 10 when they are assembled together, and reduce the risk of falling due to loose connection.

[0087] In addition, the double connection points are arranged in the extension direction of the connecting portion 21, and the fit between the connecting portion 21 and the bottom wall of the limiting groove 1131 is more compact. The connecting portion 21 can better adapt to the shape and size of the limiting groove 1131. In addition, the contact force between the connecting portion 21 and the bottom wall of the limiting groove 1131 can be effectively dispersed. This is conducive to reducing the case of excessive stress on a single point, thereby avoiding deformation or damage of the connecting portion 21 or the bottom wall of the limiting groove 1131 due to excessive local stress.

[0088] In some examples, the axis of the fixing column 40 is arranged in the Z direction, and the bearing portion 24 abuts against the side wall of the fixing column 40, which helps to prevent the support 20 from moving or shaking in the horizontal direction. At the same time, it also increases the connection strength between the support 20 and the shell 11, and improves the stability of the overall structure.

[0089] The fixing column 40 can be a pin shaft, and the bearing portion 24 can have a bayonet 241. The bearing portion 24 and the fixing column 40 form a structure similar to the pin hole cooperation. In the case where the second connection point is not connected, the sound generating module 10 and the support 20 can rotate or separate from each other. By rotating the sound generating module 10, the fixing portion 22 extends into the disassembly groove 1154, and the fixing portion 22 and the elastic clamping piece 30 are clamped to form the second connection point. Thus, the sound generating module 10 is assembled on the support 20, so that the sound generating module 10 can be used in cooperation with the support 20, and the sound generating module 10 can be prevented from accidentally falling during use. Conversely, the elastic clamping piece 30 can be pushed in the reverse direction of the X direction, so that the elastic clamping piece 30 and the fixing portion 22 are disengaged. The sound generating module 10 and the support 20 can rotate or separate from each other. By rotating the sound generating module 10, the sound generating module 10 can be separated from the support 20 to realize the disassembly of the sound generating module 10 and the support 20, thereby improving the flexibility of the assembly of the sound generating module 10 and the support 20.

[0090] Please refer to Figure 2 , Figure 3 and Figure 9The abutting portion 24 comprises a first segment 242 and a second segment 243 connected with each other, the first segment 242 is connected with the connecting portion 21 away from the second segment 243, and the second segment 243 is arranged opposite to the connecting portion 21, and at least one side of the second segment 243 towards the connecting portion 21 abuts against the side wall of the fixed column 40. In the case that the fixed portion 22 is clamped by the elastic clamping piece 30 and is tightly abutted against the second side wall by the elastic clamping piece 30, the abutting portion 24 can be limited in the Y direction by the second segment 243 and the fixed column 40, so as to prevent the abutting portion 24 from being pulled out.

[0091] Of course, in other embodiments, the part connected by the first segment 242 and the second segment 243 can be attached to the outer side wall of the fixed portion 22, so as to realize the limitation in the X direction and the Y direction; the first segment 242 and the second segment 243 can also surround the clamping opening 241, and the inner wall of the clamping opening 241 is attached to the outer side wall of the fixed column 40, so as to realize the limitation in the X direction and the Y direction, which is not limited in the embodiment.

[0092] The direction of the clamping opening 241 on the abutting portion 24 can be the same as, opposite to or opposite to the opening 1155 of the clamping groove 221 on the fixed portion 22, which is not limited in the embodiment.
