When the circuit board 8 transmits an electrical signal to the micro servo motor 505, the micro servo motor 505 rotates, that is, the slide 502 moves up and down, and a wire outlet hole 6 is opened on the upper surface of the slide 502. The bottom end of the sound transmitter 2 is coaxially installed on the slide 502 with the wire outlet hole 6. The slide 502 moves up and down to drive the sound transmitter 2 to move synchronously.
