The surface of the baffle 18 is fixedly connected with a mounting block 19, and the surface of the mounting block 19 is provided with a limited position hole. The effect of shielding the diaphragm 6 when the robot is not in use is achieved to prevent the accumulation of dust from the outside on the surface of the sound film for a long time, causing sound distortion, affecting the restoration and clarity of the sound. The inner surface of the slide groove of the upper shell 9 of the cavity shell is fixedly connected with a spring 15, and the other end of the spring 15 is fixedly connected with the slide rod 16. Pull the baffle 18 to rotate on the surface of the fixed rod 13, the baffle 18 drives the mounting block 19 to rotate, the limiting hole of the mounting block 19 is aligned with the slide bar 16, the elastic force of the spring 15 drives the slide bar 16 to slide on the inner surface of the slide groove of the upper shell 9 of the cavity shell and automatically insert into the limiting hole of the mounting block 19 to limit, thereby improving the quickness of the device.
