At the same time, after the button 5 and the mask 4 are separated from each other, there is no pulling feeling when pressing the button 5, which can improve the user experience. Thus, the technical effect of improving the waterproof performance and improving the user experience is achieved.

[0030] As an implementation mode, the button 5 includes a boss section 51 and a pressing section 52, the pressing section 52 is connected to the boss section 51, and the pressing section 52 and the boss section 51 can be integrally formed, the boss section 51 is located between the mask 4 and the waterproof isolation member 6, the projection of the pressing section 52 on the boss section 51 along the penetration direction is located on the boss section 51, and the pressing section 52 is located outside the mounting cavity 14, so that when the button 5 is pressed, the boss section 51 can be stably located on the side close to the waterproof isolation member 6, and the pressing section 52 provides convenience for the user to operate, ensuring the stability and comfort of the button 5.
