[0029] In this embodiment, a heat dissipation port 9 is provided on the top of the shell 1. There are four heat dissipation ports 9 which are evenly distributed. By providing the heat dissipation ports 9, the air flow inside the shell 1 can be facilitated under the action of the heat dissipation ports 9, thereby achieving the purpose of facilitating the discharge of heat from the shell 1.

Through the component body 2 and the speaker 11, the sound source can be amplified and played. When one side of the baffle 3 is hit by an object, under the action of external force, one side of the baffle 3 moves toward the shell 1. When the baffle 3 moves, it drives the moving plate 4 to move. When the moving plate 4 moves, the other side of the moving plate 4 moves to the inside of the shell 1, and at the same time drives the limit block 51 to slide inside the slide groove 6 to avoid displacement of the moving plate 4 when it moves. When the moving plate 4 moves, it also squeezes the spring 53 and the damping telescopic rod 52 to contract. Through the elastic force of the damping telescopic rod 52 and the spring 53 themselves, the external force exerted on the baffle 3 and the moving plate 4 can be buffered and offset, and at the same time drive the moving plate 4 and the baffle 3 to reset and move, so as to avoid the shell 1 being moved by external force collision, causing the component body 2 to shake and be damaged.
