According to the present invention, a vehicle wheel including a complex sound absorption module includes: a spoke; a rim connected with a circumferential part of the spoke; and a complex sound absorption module including a rim contact part provided to surround the circumference of the outer circumference surface of the rim, a wavelength pipe part formed to surround an at least partial length of the rim contact part to form an offset space between itself and the rim contact part, and a resonance part spaced apart from the wavelength pipe part, and formed to surround the at least partial length of the rim contact part to form a resonance space between itself and the rim contact part. The wavelength pipe part is formed into a shape wherein one side of the offset space is open and the other side is closed, to offset a resonance sound by generating a sound wave of an opposite phase to the resonance sound generated in the offset space. The resonance part is formed with a resonance neck connecting the resonance space to the outside, to absorb a resonance sound of a preset frequency range.

    본 발명에 따른 복합흡음모듈을 포함하는 차량용 휠은, 스포크, 상기 스포크의 둘레부와 연결되는 림 및 상기 림의 외주면 둘레를 감싸도록 구비되는 림 접촉부와, 상기 림 접촉부의 적어도 일부 길이를 감싸도록 형성되어 상기 림 접촉부와의 사이에 상쇄공간을 형성하는 파장관부와, 상기 파장관부와 이격되어 구비되되, 상기 림 접촉부의 적어도 일부 길이를 감싸도록 형성되어 상기 림 접촉부와의 사이에 공명공간을 형성하는 공명부를 포함하는 복합흡음모듈을 포함하며, 상기 파장관부는, 상기 상쇄공간의 일측이 개구되고 타측은 폐쇄된 형태로 형성되어, 상기 상쇄공간 내에서 발생하는 공명음에 대한 반대 위상의 음파를 발생시켜 상기 공명음을 상쇄시키도록 형성되며, 상기 공명부는, 상기 공명공간과 외부를 연통시키는 공명넥이 형성되어, 기 설정된 주파수 범위의 공명음을 흡수하도록 형성된다.
