Sound-absorbing and noise-reducing fabricated wall
The invention relates to a sound absorption and noise reduction fabricated wall which comprises a keel frame, a perforated plate, an auxiliary component, a mounting part, a movable plate, a negative pressure module, an energy consumption module and a matching module. According to the invention, targeted absorption measures are respectively set for sound waves of multiple frequency bands, the nuclear mholtz resonator composed of the movable plate, the perforated plate and the auxiliary component is used for targeted absorption of low-frequency and intermediate-frequency sound waves, and the sponge layer is used for assistance, so that the absorption frequency band is expanded, and targeted absorption of high-frequency sound waves is realized; for medium-frequency sound waves frequently appearing in daily life, a thin plate resonance sound absorption structure is constructed through the resonance plate, the reinforcing piece and the movable plate, the medium-frequency sound waves are subjected to key absorption energy consumption operation, reflection of indoor sound is reduced, noise is lowered, and the tone is clearer; interference to the outside is avoided while indoor privacy is guaranteed, and mounting and dismounting are also facilitated due to the arrangement of the matching module.
本发明涉及一种吸音降噪装配式墙体，包括龙骨架、穿孔板、辅助构件、安装件、移动板、负压模块、耗能模块、配合模块。本发明通过对多种频段的声波分别设置针对性的吸收措施，利用移动板、穿孔板、辅助构件组成的核姆霍兹共振器对低频、中频的声波进行针对性吸收，又辅以海绵层，扩大了其吸收频段，实现对高频声波的针对吸纳，对于日常生活中常出现的中频声波，本申请通过共振板、加强件、移动板构建出薄板共振吸声结构，对中频声波进行重点吸收耗能操作，减少室内声音的反射，降低噪声，使音色更加清晰，另外，本申请利用伪真空的结构进行隔音操作，保证室内私密性的同时也避免了对外界造成干扰，配合模块的设置也方便了安装与拆卸。
