Material with good sound absorption effect

Abstract

The invention provides a material with a good sound absorption effect. The material comprises a material plate and movable boxes. A cavity is formed in the material plate, mineral wool plates adhere to the inner wall of the cavity, an I-shaped support is arranged between one sides of the mineral wool plates and the inner wall of the cavity, viscose layers are arranged on the two sides of the I-shaped support, and a color glass plate adheres to one side of each viscose layer. Containing grooves are formed in the material plate, the movable boxes are arranged in the containing grooves, rail grooves are formed in the tops and the bottoms of the containing grooves, pulley strips are welded to the tops and the bottoms of the movable boxes, the pulley strips are clamped into the rail grooves, laser lamps are arranged on the tops of the movable boxes, laser lamp switches are arranged on one sides of the movable boxes, and containing cavities are formed in the movable boxes. The material withthe good sound absorption effect is novel in design, reasonable in structure, good in sound absorption effect and good in protection effect.

Description

technical field [0001] The invention is a material with good sound-absorbing effect and belongs to the field of material plate design. Background technique [0002] Material board, also known as sandwich board, is a common product in current building materials. It is not only good for flame retardant and sound insulation, but also environmentally friendly and efficient. Generally, it has good sound insulation effect. There are still some shortcomings. On the one hand, ordinary KTV rooms are generally small and closed, so the large volume generated will reverberate repeatedly. Staying in the room for a long time will cause damage to the ears. On the other hand, ordinary materials Most of the boards are simple in structure, relatively ordinary in ornamental value, and are flammable when a fire breaks out. Therefore, a material with good sound-absorbing effect is now needed to help solve the above problems. Contents of the invention [0003] Aiming at the deficiencies in the...

[0002] Material board, also known as sandwich board, is a common product in current building materials. It is not only good for flame retardant and sound insulation, but also environmentally friendly and efficient. Generally, it has good sound insulation effect. There are still some shortcomings. On the one hand, ordinary KTV rooms are generally small and closed, so the large volume generated will reverberate repeatedly. Staying in the room for a long time will cause damage to the ears. On the other hand, ordinary materials Most of the boards are simple in structure, relatively ordinary in ornamental value, and flammable in case of fire, so now a material with good sound-absorbing effect is needed to help solve the above problems
