Description

Technical Field

[0001] The invention belongs to the technical field of indoor acoustics, and in particular relates to a spatial sound absorber and an indoor sound absorption system. Background Art

[0002] The propagation of sound indoors is related to the shape, size, structure and arrangement of sound-absorbing materials in the room, while the hearing effect reflects people's subjective feelings, and there are different evaluation criteria for rooms of different uses. Some places with high requirements for sound quality need to add specific sound-absorbing materials on the basis of the original building to improve the indoor acoustic environment.

[0003] Conventional sound-absorbing materials usually take the following two forms:

[0004] 1. Cover the back of the perforated metal plate with a layer of sound-absorbing paper;

[0005] 2. Fiber sound-absorbing cloth for decoration.

[0006] The above two sound-absorbing materials have defects such as single sound absorption frequency band, high water absorption rate, easy to mold, and gradually weaken the sound absorption performance. In addition, conventional sound-absorbing materials require indoor redecoration when installed. For some large buildings with high requirements for sound quality, such as indoor gymnasiums, factories with excessive noise, theaters, libraries, cultural centers, auditoriums, etc., there are many defects such as large installation area, high cost of consumables, time-consuming and labor-intensive installation, and long installation period. Therefore, it is particularly important to seek a space sound absorber and indoor sound absorption system with good sound absorption performance, low water absorption rate, small occupied area, and flexible installation. Summary of the invention

[0007] The purpose of the present invention is to provide a spatial sound absorber and an indoor sound absorption system to solve the problems of poor sound absorption performance, high water absorption, large installation area, high consumables cost, time-consuming and labor-intensive installation, and long installation period proposed in the above background technology.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a spatial sound absorber, comprising a sound absorbing board, wherein a first sound absorbing cotton arranged vertically and a second sound absorbing cotton arranged horizontally are arranged inside the sound absorbing board, the first sound absorbing cotton is covered with a first mesh plate arranged vertically, and the second sound absorbing cotton is covered with a second mesh plate arranged horizontally.

[0009] An inner edge strip and an outer edge strip are arranged on the top of the sound absorbing board, and a plurality of mounting holes are arranged on the inner edge strip and the outer edge strip.

[0010] The sound absorbing board comprises a vertical board, the top and bottom edges of the vertical board are respectively bent inward to form a short horizontal board and a long horizontal board, the inner side edge of the long horizontal board is upwardly provided with a clamping angle, and the inner side edge of the clamping angle is bent upward to form a fourth edge.

[0011] The first sound-absorbing cotton and the second sound-absorbing cotton are arranged in an L shape, and a glue layer is provided between the first sound-absorbing cotton and the second sound-absorbing cotton.

[0012] The first mesh plate comprises a first mesh plate body arranged vertically, the top edge of the first mesh plate body is bent outwards to form a first edge, and the bottom edge of the first mesh plate body is bent outwards to form a second edge.

[0013] The second mesh plate comprises a second mesh plate body arranged transversely, the inner side edge of the second mesh plate body is bent downward to form a third edge wrapping, and the outer side edge of the second mesh plate body extends between the first sound-absorbing cotton and the second sound-absorbing cotton.

[0014] An indoor sound absorption system comprises a roof frame formed by splicing a plurality of support beams, each support beam is provided with at least one mounting surface, and a plurality of the above-mentioned spatial sound absorbers are arranged on the mounting surface along its length direction.

[0015] Compared with the prior art, the present invention provides a spatial sound absorber and an indoor sound absorption system, which have the following beneficial effects:

[0016] 1. The spatial sound absorber of the present invention has a simple structure and is suitable for large buildings with high requirements for sound quality. It can be quickly installed with the help of existing support beams in the building without occupying a large area for installation, thus reducing the cost of consumables and saving time and effort for installation. In addition, since the spatial sound absorber has a larger effective sound absorption area, it has a higher sound absorption efficiency and a good sound absorption effect.

[0017] 2. The sound-absorbing board in the spatial sound-absorbing body of the present invention is made of metal material, which has good absorption of medium and high frequency sounds. The sound-absorbing cotton is made of foamed melamine composite material, which has good absorption of medium and low frequency sounds and low water absorption. The combination of the two can greatly improve the sound absorption performance. BRIEF DESCRIPTION OF THE DRAWINGS
