Sound absorption structure

The utility model provides a sound absorption structure. The sound absorption structure comprises a plurality of sound absorption modules which are sleeved layer by layer, and sound wave incident planes of the sound absorption modules are sequentially connected to form a sound wave incident plane of the sound absorption structure; wherein at least one micropore is formed in a sound wave incident surface of the sound absorption module, and the micropore is communicated with a resonant cavity in the sound absorption module. The sound absorption structure can achieve a better sound absorption effect in a wider frequency range, is compact in structure, can reduce the space occupation of the sound absorption structure, reduces the weight of the sound absorption structure, and meets the application requirements in different scenes. 本申请提供一种吸声结构。该吸声结构包括层层套设的多个吸声模组，各吸声模组的声波入射面依次连接形成吸声结构的声波入射面；其中，吸声模组的声波入射面上开设有至少一个微孔，微孔与吸声模组内部的谐振腔连通。上述吸声结构可以在较宽的频率范围内实现较佳的吸声效果，且结构紧凑，可减少吸声结构的空间占用，降低吸声结构的重量，满足不同场景下的应用需求。
