Light and thin broadband mobile acoustic diffuser
A light and thin broadband mobile acoustic diffuser disclosed by the present invention comprises a mobile support and a diffuser body installed on the mobile support, the diffuser body comprises a plurality of single-period diffusers, each single-period diffuser comprises a square substrate, a middle-layer plate and an upper-layer plate, S * S first through hole arrays which are uniformly distributed are arranged on the middle-layer plate in a penetrating manner, S is an odd number, and S is an odd number. Wherein the side lengths of the first through holes are equal; a plurality of second through holes with unequal side lengths are formed in the upper-layer plate in a penetrating manner, and the central positions of the second through holes and the central positions of the first through holes coincide. Compared with a traditional heavy diffuser installed on a wall body, the ultra-thin diffuser has the advantages of being convenient to install and move, smooth and attractive in appearance, ultra-thin in size and free in material selection, the effect of evenly diffusing reflected sound energy in a designed broadband can be achieved, and the problem that the uniformity of a sound field in a room with the large area and the limited wall body strength is difficult to regulate and control is effectively solved.
本发明公开了一种轻薄宽带移动式声学扩散体，包括移动支架和安装在其上的扩散体本体，扩散体本体包括若干个单周期扩散体，单周期扩散体包括正方形基板、中层板和上层板，中层板上贯穿设有均匀分布的S*S第一通孔阵列，S为奇数，其中第一通孔的边长相等；上层板上贯穿设有若干个边长不等的第二通孔，第二通孔与第一通孔的中心位置重合。与传统安装于墙体的厚重扩散体相比，本发明具有安装移动方便、外形平整美观、尺寸超薄、选材自由的优点，且可以在设计的宽带内实现反射声能量均匀扩散的效果，有效解决了面积大且墙体强度受限的房间内声场均一性调控困难的问题。
