[0024] By setting the first pin hole 1 and the second pin hole 2 integrally formed with the earphone shell A, the U-shaped pin 3 can be installed and fixed, and then the seesaw button 4 can be installed on the earphone shell A through the cooperation of the U-shaped pin 3 with the first pin hole 1 and the second pin hole 2, which has the characteristics of simple structure, convenient installation and low production cost. The specific installation steps are: first place the seesaw button 4 at the corresponding position on the earphone shell A, and then move the U-shaped pin 3 downward to complete the installation, wherein when the U-shaped pin 3 moves downward, one end passes through the seesaw button 4 and is plugged into the first pin hole 1, and the other end is plugged into the second pin hole 2.

[0025] In this embodiment, the earphone shell A is formed by a mold; please refer to Figure 4 , Figure 5 Among them, the first pin hole 1 and the second pin hole 2 are both set vertically upward, which can facilitate the demoulding of the earphone shell A and effectively improve the production efficiency of the earphone shell A.

[0026] Please refer to Figure 5 The U-shaped pin 3 is formed by bending a long pin and has the characteristic of low production cost.

[0027] For further information, please refer to Figure 4 , Figure 5 The middle of the seesaw button 4 is provided with a first shaft hole 41, and one end of the U-shaped pin 3 passes through the first shaft hole 41 and is plugged into the first pin hole 1. By providing the first shaft hole 41, the seesaw button 4 and the U-shaped pin 3 can be rotatably connected, which has the characteristics of simple structure and low production cost. In another embodiment, the seesaw button 4 can also be provided on an arc surface on one side, and the seesaw button 4 and the U-shaped pin 3 can also be rotatably connected under the position restriction of the earphone shell A.

[0028] For further information, please refer to Figure 4 , Figure 5The middle part of the rocker button 4 is also provided with a second shaft hole 42, which is provided at the lower side of the first shaft hole 41; one end of the U-shaped pin 3 passes through the first shaft hole 41 and the second shaft hole 42 in sequence and then plugs into the first pin hole 1. The second shaft hole 42 is provided coaxially with the first shaft hole 41; by adding the second shaft hole 42 rotatably connected to the U-shaped pin 3, the contact area between the rocker button 4 and the U-shaped pin 3 can be increased, so that the rocker button 4 is subjected to a more uniform force, and the stability of the rocker button 4 when rotating is improved.

[0029] For further information, please refer to Figure 4 , Figure 5 A guide notch 421 is provided on one side of the second shaft hole 42 to facilitate one end of the U-shaped pin 3 to enter the second shaft hole 42. In this embodiment, the first shaft hole 41, the second shaft hole 42, and the first pin hole 1 are coaxially arranged from top to bottom. When installing the U-shaped pin 3, the U-shaped pin 3 needs to be passed through the first shaft hole 41, the second shaft hole 42 in sequence, and then plugged into the first pin hole 1. Among them, the first shaft hole 41 is at the top, which is convenient for alignment and does not need to be set up with a notch; and the first pin hole 1 needs to be plugged into the U-shaped pin 3. Setting a notch will affect the connection strength between the two and easily cause the U-shaped pin 3 to loosen, so there is no need to set a notch; and by setting a guide notch 421 on one side of the second shaft hole 42, one end of the U-shaped pin 3 can be easily inserted into the second shaft hole 42 from the guide notch 421, thereby reducing the difficulty of installation. At the same time, it is convenient for users to observe the plug-in position of the first pin hole 1 and the U-shaped pin 3 through the guide notch 421, thereby reducing the difficulty of assembling the U-shaped pin 3 and the first pin hole 1.

[0030] For further information, please refer to Figure 3 , Figure 4 , Figure 5 ,, the upper part of the first pin hole 1 is flush with the upper part of the second pin hole 2, and the depth of the second pin hole 2 is greater than the depth of the first pin hole 1; the insertion depth of the U-shaped pin 3 and the second pin hole 2 is greater than the insertion depth of the U-shaped pin 3 and the first pin hole 1. By setting the upper part of the first pin hole 1 and the upper part of the second pin hole 2 to be flush, the installation of the PCB board B can be facilitated. Among them, the first pin hole 1 is limited by the installation position of the rocker button 4 on the earphone shell A, and its setting position and height are fixed, while the setting position and depth of the second pin hole 2 are not limited; by setting the depth of the second pin hole 2 to be greater than the depth of the first pin hole 1; and the insertion depth of the U-shaped pin 3 and the second pin hole 2 is greater than the insertion depth of the U-shaped pin 3 and the first pin hole 1, the assembly area of ​​the U-shaped pin 3 and the second pin hole 2 can be further increased, thereby improving the stability of the U-shaped pin 3 and ensuring the normal use of the rocker button 4.

[0031] Furthermore, the upper part of the first pin hole 1 and the upper part of the second pin hole 2 are respectively provided with a first chamfer 11 and a second chamfer 12 for guiding the insertion of the U-shaped pin 3. In this embodiment, the assembly of the two ends of the U-shaped pin 3 with the first pin hole 1 and the second pin hole 2 is plug-in clamping; therefore, the apertures of the first pin hole 1 and the second pin hole 2 are adapted to the diameter of the U-shaped pin 3; during assembly, the two ends of the U-shaped pin 3 need to be aligned with the axis of the first pin hole 1 and the second pin hole 2 respectively to complete the assembly, and the assembly efficiency is low. Now, by adding the first chamfer 11 and the second chamfer 12, it can be used to guide the two ends of the U-shaped pin 3 to align with the first pin hole 1 and the second pin hole 2 respectively, which can effectively reduce the difficulty of installation and improve the efficiency of installation.

[0032] For further information, please refer to Figures 1 to 4 , the two ends of the U-shaped pin 3 are respectively provided with a third chamfer (not shown in the figure) and a fourth chamfer (not shown in the figure). In this embodiment, the U-shaped pin 3 is clearance-matched with the first shaft hole 41 and the second shaft hole 42, but in order to ensure the stability of the rotation of the rocker button 4, the clearance cannot be too large, and the axis needs to be aligned during assembly for normal assembly; similarly, the two ends of the U-shaped pin 3 are assembled with the first pin hole 1 and the second pin hole 2 by plugging and clamping; therefore, the apertures of the first pin hole 1 and the second pin hole 2 are adapted to the diameter of the U-shaped pin 3; during assembly, the two ends of the U-shaped pin 3 need to be respectively aligned with the axis of the first pin hole 1 and the second pin hole 2 to complete the assembly; now by adding the third chamfer and the fourth chamfer, the diameter of the two ends of the U-shaped pin 3 can be reduced, which is convenient for the assembly of the U-shaped pin 3, thereby improving production efficiency.

[0033] For further information, please refer to Figure 4 , Figure 5 A weight-reducing groove 43 is provided on the inner side of the seesaw button 4. The inner side is the side facing the inside of the earphone shell A. By adding the weight-reducing groove 43, the weight of the seesaw button 4 can be effectively reduced without affecting the structural strength of the seesaw button 4, and the production cost can be reduced at the same time.
