Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0023] The utility model provides an earphone button bearing structure, which can reduce the supporting components used to support the main board 30 in the existing earphones. When the button 40 is under pressure, the main board 30 is provided with a pulling force for balancing the pressure, thereby reducing the deformation of the main board 30, thereby preventing the main board 30 from being deformed or falling off due to frequent pressing of the button 40. While ensuring the pressing feel of the button 40, the internal space layout of the earphone is optimized, and the flexibility of stacking components inside the earphone is improved.

[0024] Please refer to Figure 1 In the present embodiment, the headphone button bearing structure comprises an upper shell 10, a lower shell 20, a main board 30 and a button 40, wherein the upper shell 10 is detachably buckled on the lower shell 20 to form a receiving cavity 50 for receiving functional components, a button slot 11 connected to the receiving cavity 50 is provided on the upper shell 10, the main board 30 is installed in the receiving cavity 50, a trigger member 31 facing the button slot 11 is provided on the main board 30, and the button 40 is installed in the button slot 11, and the button 40 can move in a direction close to or away from the trigger member 31.

[0025] Specifically, at least two first buckles 12 are provided at intervals on a surface of the upper housing 10 facing the main board 30, and second buckles 32 matching with the first buckles 12 are provided on a surface of the main board 30 facing the upper housing 10. A first guide surface (not shown) is provided on a surface of the first buckle 12 facing the matching second buckle 32; and a second guide surface (not shown) matching with the first guide surface is provided on the second buckle 32.

[0026] It is understandable that by respectively providing the first buckle 12 and the second buckle 32 that can cooperate with each other on the upper shell 10 and the main board 30, the connection between the upper shell 10 and the main board 30 is achieved, thereby playing a role in bearing the key 40 and balancing the force on the main board 30. After the key 40 is pressed and abuts against the trigger member 31, the main board 30 is subjected to pressure. By utilizing the buckling effect between the first buckle 12 and the second buckle 32, the upper shell 10 can provide a force for balancing the pressure for the main board 30, thereby reducing the deformation of the main board 30 during the pressing of the key 40, thereby avoiding the deformation or falling off of the main board 30 during the frequent pressure on the main board. At the same time, the supporting components for supporting the main board 30 inside the earphone can also be omitted, optimizing the spatial layout inside the earphone and improving the flexibility of stacking components inside the earphone.

[0027] In this embodiment, the working principle of the headphone button bearing structure is as follows: when the user presses the button 40, the button 40 moves along the button slot 11 towards the trigger member 31, and the button 40 presses against the trigger member 31 and applies pressure to the trigger member 31. The trigger member 31 then applies pressure to the mainboard 30, so that the first buckle 12 and the second buckle 32 are both elastically deformed, generating a pulling force for balancing the pressure on the mainboard, thereby reducing the deformation of the mainboard 30, thereby preventing the mainboard 30 from deforming or falling off during the pressure process.

[0028] Furthermore, in order to improve the convenience of installing the first buckle 12 and the second buckle 32 and to improve the reliability of the connection between the first buckle and the second buckle, in this embodiment, the first buckle 12 is integrally formed on the upper shell 10, and the second buckle 32 is welded to the mainboard 30.

[0029] It is easy to understand that by integrally forming the first buckle 12 on the upper housing 10, the reliability of the connection between the first buckle 12 and the upper housing 10 can be effectively improved while reducing the difficulty of installation, thereby improving the reliability of the connection between the first buckle 12 and the second buckle 32 during the pressure process. By fixing the second buckle 32 to the mainboard 30 by welding, the difficulty of installing the second buckle 32 can be reduced to a certain extent, while improving the reliability of the installation of the second buckle 32 and the mainboard 30.

[0030] Furthermore, to improve the effect of the first buckle 12 and the second buckle 32 in balancing the pressure on the mainboard 30 , in one embodiment, the first buckle 12 is respectively disposed on both sides of the key slot 11 ; the second buckle 32 is respectively disposed on both sides of the trigger member 31 .

[0031] It can be understood that by respectively arranging the first buckle 12 on both sides of the button slot 11 and respectively arranging the second buckle 32 on both sides of the trigger member 31, the pressure exerted on the main board 30 when the button 40 is pressed can be better borne, and the spatial layout inside the earphone can be arranged more reasonably.

[0032] Furthermore, the positional relationship of the first buckle 12 on both sides of the key slot 11 and the positional relationship of the second buckle 32 on both sides of the trigger member 31 will also affect the bearing effect on the headphone button 40 and the balancing effect of the pressure on the mainboard 30 to a certain extent. In a preferred embodiment, the first buckle 12 is symmetrically arranged on both sides of the key slot 11; the second buckle 32 is symmetrically arranged on both sides of the trigger member 31.

[0033] It can be understood that the first buckle 12 is symmetrically arranged on both sides of the button 40, and the second buckle 32 is also symmetrically arranged on both sides of the trigger member 31, so that when the first buckle 12 and the second buckle 32 interact with each other, the overall force is more balanced, thereby better balancing the pressure on the motherboard 30.

[0034] Furthermore, the number of the first buckle 12 and the second buckle 32 will also affect the balance between the bearing effect of the headphone button 40 and the pressure on the mainboard 30 to a certain extent. On the basis of ensuring the balance between the bearing effect of the button 40 and the pressure on the mainboard 30, from the perspective of cost-saving design, the number of the first buckle 12 and the second buckle 32 are both 2.

[0035] In a preferred embodiment, the number of the first buckles 12 and the number of the second buckles 32 are both 4. It is easy to understand that the number of the first buckles 12 and the second buckles 32 are both 4, which can achieve better bearing effect of the key 40 and pressure balance effect of the mainboard 30 while ensuring the production cost.

[0036] Furthermore, when the number of the first buckles 12 and the number of the second buckles 32 are both 4, the layout of the first buckles 12 and the layout of the second buckles 32 will affect the bearing effect of the key 40 and the pressure balance effect of the mainboard 30 to a certain extent. In a preferred embodiment, the first buckles 12 are rectangular, and the second buckles 32 are rectangular. It is easy to understand that the rectangular layout has relatively low requirements for space layout, is relatively easy to install, and the bearing effect of the key 40 and the pressure balance effect of the mainboard 30 are relatively good.

[0037] For further information, please refer to Figure 2 In one embodiment, a bearing member 13 for bearing the mainboard 30 is disposed on the side wall of the upper housing 10; and a positioning member 14 for positioning the mainboard 30 is disposed on the side wall of the upper housing 10. It can be understood that after the mainboard 30 is installed in the accommodating cavity 50, the bearing member 13 is used to provide support for the mainboard 30 so that the mainboard 30 can be stably installed in the accommodating cavity 50, and at the same time, when the mainboard 30 is under pressure, the supporting force for partially balancing the pressure is provided for the mainboard 30; and by providing the positioning member 14, the convenience of installing the mainboard 30 in the accommodating cavity 50 can be improved.

[0038] In summary, the headphone button bearing structure provided by the utility model has a first buckle 12 and a second buckle 32 that cooperate with each other on the upper shell 10 and the main board 30 respectively. By utilizing the cooperation between the first buckle 12 and the second buckle 32, a force for balancing the pressure can be provided to the main board 30 during the process of pressing the button 40, so as to reduce the deformation of the main board 30 during the process of pressing the button 40, thereby ensuring the feel of the button 40 while avoiding the deformation or falling off of the main board 30. Moreover, by providing the first buckle 12 and the second buckle 32, the supporting component for supporting the main board 30 inside the headphone can be eliminated, thereby optimizing the spatial layout inside the headphone and improving the flexibility of stacking components inside the headphone.
