The present invention relates to a sound absorber and a wheel having a sound absorber. The sound absorber (10) has a cassette structure shoring a rectangular hexahedral shape and forms a porous double-layer Helmholtz resonance sound absorbing structure, at the same time, the sound absorber (10) in the form of a cassette forms a structural resonance sound absorbing component itself, and a first-order natural mode frequency is identical to a first-order natural mode frequency of a wheel air chamber (30). When the sound absorber is assembled in the wheel by the cassette-type sound absorbing structure provided by the present invention, double functions of absorbing acoustic resonance of the wheel air chamber under the organic combination of Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.

    본 발명은 흡음장치 및 상기 흡음장치를 구비하는 휠에 관한 것이다. 상기 흡음장치(10)는 직6면체 형상을 나타내는 카세트 구조를 가지고, 다공 이중 헬름홀츠 공진 흡음 구조를 형성하며, 이와 동시에, 상기 카세트 형태의 흡음장치(10)는 자체적으로 구조 공진 흡음 부품을 형성하며, 제1단계 고유 모드 주파수는 휠 공기실(30)의 제1단계 고유 모드 주파수와 일치하다. 본 발명이 제공하는 카세트식 흡음 구조에 의해, 상기 흡음장치를 휠에 조립 시, 헬름홀츠 공진 흡음과 구조 공진 흡음이 유기적으로 결합된 휠 공기실 음향 공진의 이중 흡수 기능을 실현할 수 있다.
