[0026] The following is the content of the first aspect of the present invention:

[0027] Please refer to Figure 1 This invention provides a snap-fit ​​assembly that can be applied to the pressing of an earphone shell. The snap-fit ​​assembly includes a first pressing assembly 1, a second pressing assembly 2, a first cavity 3, a second cavity 4, a snap-fit ​​component 5, and a stop assembly 6.

[0028] The first pressing assembly 1 and the second pressing assembly 2 form an integral load-bearing structure for the snap-fit ​​pressing assembly. The first cavity 3 and the second cavity 4 are used to install the parts to be pressed. The snap-fit ​​components are used to fasten the first pressing assembly 1 and the second pressing assembly 2 to ensure proper pressing. The abutting assembly 6 is used to press the first cavity 3 and the second cavity 4 tightly. The pressing force can be adjusted by the abutting assembly 6 to ensure the accuracy of the pressing force.

[0029] The first cavity 3 is installed in the first pressing assembly 1, the second cavity 4 is installed in the second pressing assembly 2, the abutting assembly 6 is disposed in the first pressing assembly 1 and abuts against the first cavity 3; the fastening assembly 5 is installed on the side wall of the first pressing assembly 1, and the first pressing assembly 1 can fasten to the second pressing assembly 2 to press the first cavity 3 and the second cavity 4 together.

[0030] Specifically, existing headphone shells typically consist of a front shell and a rear shell. During the headphone shell pressing process, the operator first installs the front shell and rear shell into the first cavity component 3 and the second cavity component 4, respectively. Then, the first cavity component 3 and the second cavity component 4 are installed into the first pressing assembly 1 and the second pressing assembly 2, respectively. Next, the first pressing assembly 1 and the second pressing assembly 2 are closed together. The operator then applies pressure to the first pressing assembly 1 manually or mechanically until the fastening piece 5 mounted on the first pressing assembly 1 engages with the second pressing assembly 2, and the abutment assembly 6 applies pressure to the first cavity component 3 and the second cavity component 4. After the first pressing assembly 1 engages with the second pressing assembly 2, the pressing assembly is left to stand. After a preset time, the operator opens the fastening piece 5 to disengage it from the second pressing assembly 2, then separates the first pressing assembly 1 and the second pressing assembly 2, removes the headphone shell, and completes the headphone shell pressing operation.

[0031] It is understandable that by utilizing the first pressing component 1, the second pressing component 2, the abutting component 6, and the fastening component 5, the first cavity component 3 and the second cavity component 4 can be pressed together, thereby achieving the pressing of the earphone shell, improving the control precision of the pressing force, improving the uniformity of the pressure on the earphone shell, reducing the influence of air pressure on the overall pressing effect, and improving the overall pressing effect of the earphone shell.

[0032] For further details, please refer to... Figure 1 In one embodiment, the first pressing assembly 1 includes a first pressing outer mold 11 and a first pressing inner mold 12 installed in the first pressing outer mold 11; the second pressing assembly 2 includes a second pressing outer mold 21 and a second pressing inner mold 22 installed in the second pressing outer mold 21.

[0033] The first pressing outer mold 11 serves as the pressure-bearing component of the snap-fit ​​assembly and the mounting component of the first pressing inner mold 12; the first pressing inner mold 12 serves as the mounting component of the first cavity component 3. The second pressing outer mold 21 serves as the mounting component of the second pressing inner mold 22, and the second pressing inner mold 22 serves as the mounting component of the second cavity component 4.

[0034] Specifically, the first pressing component 1 is a detachable component, meaning that the first pressing outer mold 11 and the first pressing inner mold 12 are detachably connected, and the first pressing inner mold 12 and the first cavity component 3 are also detachably connected. Similarly, the second pressing component 2 is a detachable component, meaning that the second pressing outer mold 21 and the second pressing inner mold 22 are detachably connected, and the second pressing inner mold 22 and the second cavity component 4 are also detachably connected. It can be understood that this detachable connection method better addresses the pressing process of the earphone shell, improves the convenience of maintenance and replacement of the first pressing component 1 and the second pressing component 2, and enhances the compatibility of the first pressing component 1 and the second pressing component 2.

[0035] Furthermore, in one embodiment, the second pressing outer mold 21 and the second pressing inner mold 22 are respectively equipped with mutually cooperating magnetic components. The magnetic components are used to assist in the installation between the second pressing outer mold 21 and the second pressing inner mold 22.

[0036] It is understandable that by installing magnetic components on the second pressing outer mold 21 and the second pressing inner mold 22 respectively, the installation positioning between the second pressing outer mold 21 and the second pressing inner mold 22 can be effectively assisted, and the installation stability between the second pressing outer mold 21 and the second pressing inner mold 22 can be improved to a certain extent.

[0037] For further details, please refer to... Figure 3 and Figure 4 In one embodiment, a first disassembly groove 121 is provided on the side wall of the first pressing inner mold 12; and a second disassembly groove 221 is provided on the side wall of the second pressing inner mold 22.

[0038] The first disassembly groove 121 is an auxiliary structure for disassembling the first cavity component 3 from the first pressing inner mold 12, and the second disassembly groove 221 is an auxiliary structure for disassembling the second cavity component 4 from the second pressing inner mold 22.

[0039] Specifically, the first pressing inner mold 12 has a first groove 32 for mounting the first cavity component 3, and the second pressing inner mold 22 has a second groove 42 for mounting the second cavity component 4. A first disassembly groove 121 is disposed on the side wall of the first pressing inner mold 12 and communicates with the first groove 32, and a second disassembly groove 221 is disposed on the side wall of the second pressing inner mold 22 and communicates with the second groove 42. A positioning post 123 is formed on the first pressing inner mold 12, and a positioning hole 222 is formed on the second pressing inner mold 22 to mate with the positioning post 123.

[0040] Preferably, there are two first disassembly grooves 121 and two second disassembly grooves 221. The two first disassembly grooves 121 are disposed opposite each other on the side of the first pressing inner mold 12, and the two second disassembly grooves 221 are disposed opposite each other on the side wall of the second pressing inner mold 22. It is easy to understand that by providing two first disassembly grooves 121 and two second disassembly grooves 221 respectively, the convenience of picking up the first cavity component 3 and the second cavity component 4 can be better improved.

[0041] It is understandable that by setting the first disassembly groove 121, the convenience and efficiency of disassembling the first cavity component 3 from the first pressing inner mold 12 can be improved, and by setting the second disassembly groove 221, the convenience and efficiency of disassembling the second cavity component 4 from the second pressing inner mold 22 can be improved, thereby improving production efficiency.

[0042] For further details, please refer to... Figure 1 In one embodiment, one end of the fastening member 5 is rotatably connected to the side wall of the first pressing outer mold 11.

[0043] Specifically, there are two fastening components 5, which are rotatably connected to the side wall of the first pressing outer mold 11. After the first pressing assembly 1 and the second pressing assembly 2 merge together, pressure is applied to the first pressing outer mold 11, and the first pressing assembly 1 gradually moves towards the second pressing assembly 2. As the first pressing assembly 1 moves, the fastening components 5 also move towards the second pressing outer mold 21, fastening the fastening components 5 into the second pressing outer mold 21, thereby completing the pressing of the first pressing assembly 1 and the second pressing assembly 2.

[0044] For further details, please refer to... Figure 2 In one embodiment, the abutting component 6 includes an abutting member 61, a connecting member 62, and an elastic member 63; one end of the abutting member 61 is connected to the first pressing outer mold 11, and the other end of the abutting member 61 abuts against the first cavity member 3; the connecting member 62 is installed on the first pressing inner mold 12; and the elastic member 63 is connected between the first pressing outer mold 11 and the connecting member 62.

[0045] The abutment member 61 is used for pressing between the first cavity member and the second cavity member. The elastic member 63 is used for detecting the pressing force and for pressing buffering. The connecting member 62 is used to connect the elastic member 63 and is an auxiliary structure for the elastic member 63.

[0046] Specifically, the first pressing inner mold 12 has a guide hole 122 communicating with the first groove 32, through which the abutment 61 abuts against the first cavity 3. When the first pressing assembly 1 and the second pressing assembly 2 merge together, pressure is applied to the first pressing outer mold 11. The first pressing outer mold 11 drives the abutment 61 to move towards the second pressing outer mold 21, and the abutment 61 squeezes the first cavity 3, so that the first cavity 3 presses against the second cavity 4. During the movement of the first pressing outer mold 11 towards the second pressing outer mold 21, the elastic body is compressed under the action of the first pressing outer mold 11 and the connecting member 62. By calculating the deformation of the elastic body 63, the corresponding pressing force can be determined, thereby adjusting the pressing force.

[0047] It is understandable that by setting the abutment 61, the connecting part 62 and the elastic part 63, the control accuracy of the pressing force can be improved, the uniformity of the pressure on the earphone shell can be improved, and thus the overall pressing effect of the earphone shell can be improved.

[0048] For further details, please refer to... Figure 5 and Figure 6 In one embodiment, one end of the first cavity member 3 is provided with a first chamfered portion 31, and one end of the second cavity member 4 is provided with a second chamfered portion 41.

[0049] It is understandable that by setting the first chamfered part 31 and the second chamfered part 41, the misalignment of the first cavity part 3 and the second cavity part 4 can be effectively avoided, which can effectively reduce the number of shell damages during the earphone shell pressing process and reduce the production defect rate.

[0050] For further details, please refer to... Figure 6 In a preferred embodiment, a first through groove 43 is formed within the second cavity 4. The first through groove 43 is used for disassembling the housing of the second cavity.

[0051] It is easy to understand that the second cavity 4 is a press-fitted load-bearing structural component. By opening the first through groove 43 on the second cavity 4, the ease of disassembling the earphone shell on the second cavity 4 can be improved, the disassembly efficiency after the earphone shell is pressed can be improved, and thus the production efficiency can be improved.

[0052] For further details, please refer to... Figure 1 In a preferred embodiment, a guide post 7 is installed between the first pressing component 1 and the second pressing component 2. The guide post 7 serves as a guiding auxiliary structure during the merging process of the first pressing component 1 and the second pressing component 2.

[0053] Specifically, there are two guide posts 7. The two guide posts 7 can be set on the first pressing component 1 or on the second pressing component 2. Preferably, the guide posts 7 are set on the second pressing component 2.

[0054] It is understandable that by installing guide posts 7 between the first pressing component 1 and the second pressing component 2, the efficiency and accuracy of merging between the first pressing component 1 and the second pressing component 2 can be improved, production efficiency can be increased, and the stability of the pressing process can be ensured, thereby improving the overall pressing effect.

[0055] In summary, the snap-fit ​​assembly provided by the present invention, by utilizing the first pressing assembly 1, the second pressing assembly 2, the abutting assembly 6 and the fastening member 5, can realize the mutual pressing of the first cavity member 3 and the second cavity member 4, thereby realizing the pressing of the earphone shell, improving the control accuracy of the pressing force, improving the uniformity of the pressure on the earphone shell, reducing the influence of air pressure on the overall pressing effect, and improving the overall pressing effect of the earphone shell.
