Acoustic metamaterial sound absorption shutter structure
The acoustic metamaterial sound absorption shutter structure comprises a plurality of silencing shutter strips, a mounting frame used for mounting the silencing shutter strips and a driving mechanism used for driving the silencing shutter strips to conduct angle adjustment and/or lifting adjustment. Each silencing shutter strip comprises a body frame, a high-reflectivity film and a plurality of mass blocks. The end part of the body frame is rotationally connected with the mounting frame, and a plurality of through holes are formed in the body frame and penetrate through the upper and lower surfaces of the body frame; films are attached to the upper surface and the lower surface of the body frame, so that the through holes are closed to form air cavities; the mass blocks are arranged in the air cavity, and the mass blocks are fixedly connected to the films on the upper and lower surfaces of the air cavity; a sound absorption unit cell is formed by the thin film, the air cavity and the mass block in the air cavity, a noise elimination unit is formed by at least one sound absorption unit cell, and a plurality of noise elimination units are arranged in the length direction of the noise elimination louver strip. The multifunctional silencer has the functions of angle adjustment, lifting adjustment, outdoor noise pollution reduction and the like, and particularly has high noise elimination performance in a low-frequency band.
本发明公开一种声学超材料吸声百叶结构，包括若干消声百叶条，用于安装消声百叶条的安装架，及用于驱动消声百叶条进行角度调节和/或升降调节的驱动机构；消声百叶条包括本体框架、高反射性薄膜和若干质量块；本体框架的端部与安装架转动连接，其上设有若干通孔，通孔贯穿本体框架的上下表面；本体框架的上下表面均贴合有薄膜，以使通孔封闭形成空气腔；质量块设在空气腔内，且空气腔上下面的薄膜上均固定连接有质量块；由薄膜、空气腔及其内的质量块构成一个吸声单胞，由至少一个吸声单胞构成一个消声单元，消声单元沿着消声百叶条的长度方向设有若干个。本发明兼具角度调节、升降调节、降低室外噪声污染等功能，尤其在低频段具有较高消声性能。
