Novel metal Slott sound absorption board
The invention belongs to the technical field of sound absorption, sound insulation, sound elimination and noise reduction, and particularly relates to a novel metal Slott sound absorption board. According to the sound absorption board, one-time forming is firstly achieved through a customized mold, then multiple times of deep machining are carried out, and a reasonable three-dimensional sound absorption principle is created. According to the three-dimensional sound absorption principle, protruding strip-shaped supporting ribs and gaps between the adjacent strip-shaped supporting ribs form sound elimination and transmission cavities, and then the acoustic principle that the inner walls of the sound elimination and transmission cavities are perforated is combined. According to the sound absorption board, through the acoustical principle that the strip-shaped supporting ribs, sound transmission cavities and rectangular holes are arranged, multi-directional and multi-angle reflection, refraction and absorption to a sound source are achieved, the aims of sound elimination, sound absorption, noise reduction and reverberation time improvement are achieved, after the sound source enters the sound transmission cavities from sound inlets and then is absorbed through the rectangular holes in the inner walls, in combination with a manner of filling sound absorption cotton in product structure process inner structures to achieve sound absorption, sound energy is converted into heat energy, and therefore the aims of sound elimination, sound absorption, noise reduction and reverberation time improvement are achieved again.
本发明属于吸声、隔声、消声、降噪技术领域,尤其是一种新型金属斯洛特吸声板,吸声板首先用定制模具一次成型,再进行多次深加工,打造出合理的立体吸声原理,所述立体吸声原理由突出的条状撑筋和相邻条状撑筋之间的空隙形成消透声空腔,再结合消透声空腔内壁穿孔的声学原理组成。该吸声板通过设置条状撑筋、透声空腔和矩形孔的声学原理,达到了对声源多方位和多角度反射、折射、吸收,而实现消声、吸声、降低噪声和改善混响时间的目的,声源从入声口进入透声空腔后再通过内壁的矩形孔吸收后,结合产品结构工艺内构填充吸声棉吸声的方式,让声能转化为热能,从而再实现消声、吸声、降低噪声和改善混响时间的目的。
