The silencing device comprises a body, a silencing pipe and a silencing cavity, the silencing pipe and the silencing cavity are arranged in the body, a silencing opening is formed in the side wall of the body, the silencing pipe is arranged in the body, one end of the silencing pipe is communicated with the silencing opening, the silencing cavity is arranged in the body, and the other end of the silencing pipe is communicated with the silencing opening. The silencing cavity is communicated with the other end of the silencing pipe, and a plurality of elastic baffles are arranged in the silencing cavity. Therefore, after the plurality of elastic baffles are arranged, the sound wave dissipation effect can be enhanced, the attenuation effect of resonance noise is effectively enhanced, and even if the frequency of incident sound waves is far away from the inherent frequency of the resonator, a certain silencing effect can be achieved, so that the resonance sound of a tire cavity can be reduced in a broadband range, and the noise reduction effect is greatly improved.
本发明公开了一种消声装置、消声轮毂及车轮,包括本体以及设于本体内的消声管和消声腔,所述本体的侧壁上设有消声口,所述消声管设于所述本体内,所述消声管的一端与所述消声口连通,所述消声腔设于所述本体内,所述消声腔与所述消声管的另一端连通,所述消声腔内设有若干个弹性挡板。由此,通过设置若干个弹性挡板后,可以增强声波耗散效果,有效地加强了共振噪声的衰减效果,即使当入射声波频率远离共振器固有频率时,也能起到一定的消声作用,从而可以在宽频范围内降低轮胎空腔共振声,极大地提高了降噪效果。
