The invention relates to a sound absorber unit and a wheel with a sound absorbing device. The sound absorbing device comprises at least one sound absorber unit (10) or at least one sound absorber assembly formed by combining a plurality of sound absorber units into a whole. The sound absorber unit is configured as a box in the shape of a rectangular hexahedron and forms a two-hole double-layer Helmholtz resonance sound absorption structure, and meanwhile, the sound absorber unit or the sound absorber assembly itself forms a structural resonance sound absorption device. According to the invention, the function of dual absorption of wheel air chamber acoustic resonance, which organically combines Helmholtz resonance sound absorption and structural resonance sound absorption, can be realized.
本申请涉及吸声器单元和具有吸声装置的车轮,所述吸声装置包括至少一个吸声器单元(10)或者包括至少一个由多个吸声器单元组合为整体的吸声器组件。所述吸声器单元构造为呈长方六面体状的盒体并形成一种两孔双层赫姆霍兹共振吸声结构,同时,所述吸声器单元或所述吸声器组件自身形成一种结构共振吸声器件。根据本申请,可以实现赫姆霍兹共振吸声和结构共振吸声有机结合的双重吸收车轮气室声共振的功能。
