The electromagnet 271c is electrically connected with the main board 40, when the box body 622 needs to slide out of the accommodating space 22, the main board 40 supplies power to the electromagnet 271c, so that the magnetic poles between the electromagnet 271c and the magnet 273c are the same and mutually repel, and the box body 622 can be driven to extend out of the accommodating space 22, so that the camera module 68 can be conveniently used; when the case 622 needs to be retracted into the accommodating space 22, the main board 40 supplies power to the electromagnet 271c and changes the direction of the power supply, so that the magnetic poles between the electromagnet 271c and the magnet 273c are different and attract each other, thereby driving the case 622 to be retracted into the accommodating space 22, at this time, the sound outlet channel of the case 622 faces the sound through hole 201 of the casing 20, the abutting piece 65 is clamped between the case 622 and the casing 20, and the channel between the sound outlet channel 620 and the sound through hole 201 is in a sealed state, which is beneficial to the transmission of the sound of the receiver 64.

In the fifth embodiment, two slide guiding mechanisms are provided, and during the process of extending or retracting the box body 622 into the accommodating space 22, each slide guiding column 278 slides along the slide guiding hole of the corresponding positioning block 2782, and the corresponding stop block 2784 can stop at an end of the corresponding positioning block 2782 far away from the box body 622, so as to prevent the box body 622 from being separated from the housing 20.

The foregoing is illustrative of embodiments of the present invention, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the embodiments of the present invention and are intended to be within the scope of the present invention.
