The invention relates to a ventilation and noise reduction structure and device and electric equipment, the ventilation and noise reduction structure comprises a first shell and a second shell, the first shell is enclosed to form a ventilation channel, the second shell is sleeved outside the first shell, a cavity is formed by the second shell and the first shell, and the ventilation channel is communicated with the second shell. The first shell is provided with at least one through hole which is communicated with the ventilation channel and the cavity, and the through hole is used for reducing noise; therefore, an effective resonance noise reduction structure is formed through the cavity and the through holes, the resonator structure is combined with the ventilation channel, under the condition that ventilation is guaranteed, a sound insulation wide spectrum can be effectively formed, noise in a wide frequency range is blocked, and therefore the wide-spectrum sound insulation effect on sound waves of different frequencies is achieved while the ventilation effect is guaranteed.
本公开涉及一种通风降噪结构、装置及用电设备,该通风降噪结构,包括第一壳体和第二壳体,所述第一壳体围成通风通道,所述第二壳体套设在所述第一壳体外,与所述第一壳体形成腔室,所述第一壳体上设有至少一个连通所述通风通道与所述腔室的通孔,所述通孔用于降噪;这样通过腔室和通孔形成了有效的共振消音结构,该共鸣器结构与该通风通道相结合,能够在保证通风的情况下,有效形成隔声宽谱,阻挡较宽频率范围的噪声,从而达到在保证通风效果的同时实现对不同频率声波的宽谱隔声效果。
