L-shaped indoor double-layer ultra-micropore structure sound absorption body
The invention discloses an L-shaped indoor sound absorption body with a double-layer ultra-microporous structure. The sound absorption body is a cavity body which is defined by ultra-micropore metal sound absorption plates and extends in the longitudinal direction, the sound absorption body is of a double-layer ultra-micropore structure, and the cross section of the sound absorption body is in an L shape. According to the sound absorption body ultra-micropore metal sound absorption plate, ultra-micropores with the diameter smaller than or equal to 0.2 mm are evenly punched in the metal plate face. The sound absorption body is provided with a hanging accessory, and the hanging accessory comprises a top fixing sectional material or a side wall fixing sectional material and a hanging piece sectional material. The L-shaped bottom edge of the sound absorption body automatically abuts against the wall body under the action of gravity, and a second cavity is formed after the sound absorption body is installed. The L-shaped indoor double-layer ultra-micropore structure sound absorption body is hung on an indoor top plate along the indoor periphery, the lower portion of the sound absorption body abuts against a wall body or the side face of a bearing beam body, and a second cavity is formed between the sound absorption body and the wall body or the bearing beam body. The good sound absorption performance of the ultra-micropore structure is fully utilized, and meanwhile sound waves are repeatedly reflected and scattered in the two cavities and are combined with resonance, so that the purpose of better sound absorption and noise reduction is achieved.
本发明公开了一种L型室内双层超微孔结构吸音体。吸音体是超微孔金属吸声板围成的纵向延伸的空腔体，为双层超微孔结构，吸音体横截面呈L型。所述吸音体超微孔金属吸声板，金属板面上均匀冲制直径≤0.2mm的超微孔。所述吸音体配置悬挂配件，所述悬挂配件包括顶部固定型材或侧墙固定型材和挂件型材。在重力作用下吸音体L型底边自动抵靠在墙体上，吸音体安装完毕形成第二空腔。本发明L型室内双层超微孔结构吸音体，沿着室内四周悬挂于室内顶板上，吸音体的下部抵靠在墙体上或承重梁体侧面，吸音体与墙体或梁体间形成第二空腔。充分利用了超微孔结构良好的吸音性能的同时，声波在两个空腔中反复反射散射辅之以共振，达到更好的吸音消音之目的。
