The utility model provides an audio amplifier as long as utilize the container blow molding mouth that leaves when the blow molding can be in order to accomplish the assembly of whole audio amplifier, then carry out the shaping through the technology of punching press + the rubber coating of moulding plastics to the components and parts mounting structure at the audio amplifier back, need not to cut the opening to the back, has guaranteed the wholeness of container, and the performance of audio amplifier box is better, and the assembly is also simpler.

3. The utility model provides a sound box, only the air outlet of blowing mouth part and passive vibrating diaphragm unit need seal after the sound production subassembly of packing into, sealed girth is shorter, sealed easy realization and the effect is lasting. The traditional sound box has too long sealing perimeter, and is easy to have the problems of partial sealing failure or partial resonance generation.

4. The utility model provides a sound box can more complicated structure of shaping through injection molding process to can install more button, sound outlet etc. on letting the sound box. And the injection molding structure can be adhered with the original blow molding box body to form a whole, so that the strength is greatly increased.

5. The utility model provides a loudspeaker box, the box surface need not to cut again except that the blowing mouth forms new opening, and the box uniformity is than better, and intensity is than higher.
