Silencer structure

A silencer structure, comprising:

• a housing having two open ends, the housing including an accommodating chamber therein and extending along an extending direction for guiding an air flow and a sound wave to flow along the extending direction;
• at least one noise-reducing module, provided in the accommodating chamber, comprising:
• two first noise-reducing plates that are spaced apart from each other, the two first noise-reducing plates extend along the extending direction, respective two ends of the two first noise-reducing plates being connected to two fixing plates, a first cavity being formed between the two first noise-reducing plates;
• each of the first noise-reducing plates being formed with a plurality of micro-perforations, each of the micro-perforations being perpendicular to the extending direction, the micro-perforations each having a diameter less than a thickness of the first noise-reducing plates;
• at least one second noise-reducing plate, provided in the first cavity, the second noise-reducing plate being perpendicular to the first noise-reducing plates and the extending direction, a plurality of first noise-reducing spaces being formed between the first noise-reducing plates and the second noise-reducing plate.
