Fix the audio amplifier through two rubber packing rings, play absorbing effect to the audio amplifier.

Preferably, the inner wall of the upper shell is provided with an annular air bag, and the inner wall of the annular air bag is connected with the outer surface of the loudspeaker main body. The setting through annular gasbag can play the effect of shock attenuation buffering to the speaker main part, can prevent simultaneously that dust impurity from entering into inside the audio amplifier from the loudspeaker mouth.

Compared with the prior art, the utility model has the following beneficial effects:

1. according to the loudspeaker box, the grooves and the reinforcing ribs are arranged, so that the strength of the injection molding iron sheet on the loudspeaker box shell can be improved, the loudspeaker box shell is prevented from being deformed and protruded, the strength of the injection molding iron sheet can be improved through the arrangement of the reinforcing ribs, and the injection molding iron sheet is prevented from being deformed.

2. According to the utility model, through arranging the damping springs and the annular air bags, the effect of damping and buffering the loudspeaker in the sound box is achieved, so that the loudspeaker is prevented from being damaged by vibration, and the service life of the sound box is prolonged.
