Abstract

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.

Description

technical field [0001] The invention relates to the technical fields of sound absorption, sound insulation, noise elimination and noise reduction, and in particular to a novel metal slotted sound-absorbing panel. Background technique [0002] Acoustic panels are an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic, simple construction, good stability, good impact resistance, good independence, and high cost performance. A variety of colors are available to meet the needs of different styles and levels of sound-absorbing decoration. [0003] Many of the existing sound-absorbing panels rely on the area of ​​the panel. To achieve the sound-absorbing effect from a two-dimensional perspective, more rely on the material itself. The echo is reflected vertically. In addition, each board is...
