摘要:
The application relates to a wheel with a sound absorption device, wherein the sound absorption device is arranged in a wheel air chamber to reduce acoustic resonance, the sound absorption device comprises two resonance sound absorption structure units which are connected in parallel, a first sound absorption frequency band of a first resonance sound absorption structure unit and a second sound absorption frequency band of a second resonance sound absorption structure unit are adjacent to each other or partially overlap with each other, and the resonance frequency of the wheel air chamber is contained at the adjacent part of the first sound absorption frequency band and the second sound absorption frequency band or in the overlapping area of the first sound absorption frequency band and the second sound absorption frequency band.
