Sound absorption decorative box

Abstract

The invention relates to a sound absorption decorative box. The sound absorption decorative box is composed of a sound absorption box, a round cup sound insulation board and a cover plate, wherein thesound absorption box and the cover plate are assembled together; the round cup sound insulation board is arranged between the sound absorption box and the cover plate; a circle of L-shaped openings II in the inner face of the cover plate are formed in a circle of L-shaped openings I in the back face of the sound absorption box and are in butt joint together; a plane is formed by the back face ofthe cover plate and the upper faces of the circle of L-shaped openings I; eight fixing pipes on the inner face of the cover plate penetrate eight semicircular grooves in the periphery of the round cupsound insulation board and correspondingly sleeve eight positioning columns of the sound absorption box and are bonded to the eight positioning columns of the sound absorption box together through glue, and the sound absorption box, the round cup sound insulation board and the cover plate are fixed into a whole; and various sound waves are absorbed through a plurality of sound absorption counterbores of the sound absorption box and then enter a large-diameter sound insulation cup and a small-diameter sound insulation cup, sound wave energy is consumed through sound wave reflection interference, the sound waves are weakened to a great degree, the sound wave energy is reduced, and the purpose of noise blocking is achieved.

Description

technical field [0001] The invention relates to a sound-absorbing decorative box, which is a sound-absorbing decorative board used for indoor walls and roofs, and absorbs and blocks indoor space noise. Background technique [0002] At present, indoor wall and roof decoration materials have no sound absorption function, but only have a decorative effect. Some large spaces, such as movie theaters, railway stations, airports, etc., have serious internal noise, which affects people's hearing. [0003] At present, most of the decoration materials with internal space sound insulation are sound-absorbing cotton, wood wool board, soft packaging materials, etc. These materials have serious deficiencies in environmental protection, fire protection, durability, etc., mainly in the following aspects: [0004] 1. At present, most of the products are gypsum boards, aluminum boards, etc., which do not have any noise blocking function, and the sound insulation ability is poor. [0005] 2...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, most of the products are gypsum boards, aluminum boards, etc., which do not have any noise barrier function, and the sound insulation ability is poor

[0005] 2. At present, the sound-absorbing cotton and soft package materials of the product are mostly chemical synthesis products, and the sound-absorbing cotton will slowly fly away with use, which will have an adverse effect on the indoor environment, and the sound-absorbing cotton will affect the health of personnel.

[0006] 3. The wood wool board and soft bag in the current products are flammable materials due to the constraints of the material itself, and do not have fire resistance

[0007] 4. Wood wool boards and gypsum boards in current products are affected by changes in ambient temperature and humidity, resulting in deformation, discoloration, and low durability

[0008] 5. The existing technical products have various styles, different specifications, and different installation methods. The construction is difficult, and the amount of maintenance work in the later period is large.
