Abstract
A sound absorber unit and a vehicle wheel having a sound absorber device are provided. The sound absorber devices includes at least one sound absorber unit or at least one sound absorber assembly which is composed of a plurality of sound absorber units. The sound absorber unit is constructed into a box body in a hexahedron shape and forms a three-layer Helmholtz resonance sound absorption structure with double holes and single holes combined, and meanwhile, the sound absorber unit or the sound absorber assembly forms a structural resonance sound absorber. The double-absorption wheel air chamber sound resonance function organically combining Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.
