Super-ventilation acoustic metamaterial silencing cover
The invention provides an ultra-ventilation acoustic metamaterial silencing cover which comprises a silencing cover framework, the silencing cover framework is of a vertical rectangular frame structure, and each exposed face of the silencing cover framework is filled with at least one square pipe to form a ventilation sound absorption wall. The square pipe penetrates through the interior and the exterior of the silencing cover, acoustic metamaterial sound absorption patches are laid on a circle of the inner wall of the square pipe, and a ventilation and noise reduction channel is defined by the circle of acoustic metamaterial sound absorption patches on the inner wall; each acoustic metamaterial sound absorption patch comprises a patch shell, a plurality of metamaterial sound absorption units which are arranged in a horizontal matrix are arranged in each patch shell, each metamaterial sound absorption unit comprises at least four metamaterial sound absorption structures, and the metamaterial sound absorption structures are rotationally symmetrical about the center of the corresponding metamaterial sound absorption unit; a sound absorption inlet is formed in the position, corresponding to the center of each metamaterial sound absorption unit, of the top face of the patch shell, and each metamaterial sound absorption structure is communicated with the sound absorption inlet. The problems of noise elimination and heat dissipation of the noise device can be solved at the same time.
本发明提出了一种超通风声学超材料消音罩，包括消音罩骨架，消音罩骨架为立式矩形框架结构，消音罩骨架的各裸露面均通过至少一个方形管充满，以形成通风吸声墙；方形管贯通消音罩内、外，在方形管的内壁一圈铺有声学超材料吸声贴片，且内壁的一圈声学超材料吸声贴片围成通风降噪通道；单个声学超材料吸声贴片包括贴片外壳，其内设有呈水平矩阵排列的多个超材料吸声单元，单个超材料吸声单元包括至少四个超材料吸声结构，各超材料吸声结构关于超材料吸声单元的中心旋转对称；在贴片外壳的顶面对应每个超材料吸声单元的中心位置处均设有吸声入口，每个超材料吸声结构分别与吸声入口相通。本发明能同时解决噪声装置的消声与散热问题。
