Noise reduction structure and noise reduction assembly
The invention provides a noise reduction structure and a noise reduction assembly, relates to the technical field of noise reduction, and aims to solve the problem that ventilation and noise reduction cannot be effectively considered in a traditional structure. The noise reduction structure comprises a cavity, a cavity is formed in the cavity, and the outer surface of the cavity is provided with a first outer surface and a second outer surface which are arranged away from each other; the cavity is further provided with a channel for air circulation, the channel is provided with a first port and a second port, the first port is located on the first outer surface, and the second port is located on the second outer surface; the side wall of the channel is provided with a through hole, and the channel is communicated with the cavity through the through hole. Wherein the structure formed by the cavity and the through hole can be understood as a Helmholtz resonator, sound waves penetrating through the channel can be effectively weakened, and therefore the noise reduction effect is achieved.
本申请提供了一种降噪结构和降噪组件，涉及降噪技术领域，以解决传统结构不能有效兼顾通风和降噪的问题。本申请提供的降噪结构包括腔体，腔体内具有空腔，并且在腔体的外表面具有相互背离设置的第一外表面和第二外表面；腔体还具有供空气流通的通道，通道具有第一端口和第二端口，第一端口位于第一外表面，第二端口位于第二外表面；通道的侧壁具有通孔，通道和空腔之间通过通孔连通。其中，空腔和通孔所组成的结构可以理解为亥姆霍兹共鸣器，可以对穿过通道的声波进行有效的削弱，从而起到降噪的效果。
