Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing material manufacturing, and more specifically to an elastic sound-absorbing board. Background Art

[0002] At present, most projects in the market use glass wool or rock wool as sound-absorbing fabrics, which are loose raw materials. This direct construction method is not only long-term and troublesome, but also does not meet environmental protection and labor protection conditions. The sound absorption effect of the few glass wool sound-absorbing panels currently available in China is not ideal, especially for low-frequency silencing, which makes the low-frequency reverberation time too long and the sound quality of the hall unclear.

[0003] Therefore, how to provide an elastic sound-absorbing panel with a long service life and capable of ensuring effective sound absorption after long-term use is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0004] In view of this, the utility model provides an elastic sound-absorbing panel, aiming to solve the problems in the above-mentioned background technology, to extend the service life of the sound-absorbing panel and to ensure that the sound-absorbing panel can still be effectively used after long-term use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An elastic sound-absorbing panel, comprising:

[0007] Elastic sound absorbing substrate;

[0008] Side fabrics, wherein a plurality of the side fabrics are provided, and the plurality of the side fabrics are connected to each other and wrapped around the side of the elastic sound-absorbing substrate;

[0009] A top cloth, the top cloth covers the top of the elastic sound-absorbing board, and the bottom surface of the top cloth is connected to the top of the side cloth;

[0010] A bottom surface cloth is arranged on the bottom surface of the elastic sound absorbing board, and a top surface edge of the bottom surface cloth is connected to the bottom of the side panel.

[0011] Furthermore, the bottom surface cloth is provided with a hollow opening, and the hollow opening passes through the middle part of the bottom surface cloth and connects the bottom surface and the outside of the elastic sound-absorbing substrate.

[0012] It can be seen from the above technical solution that compared with the prior art, the utility model discloses an elastic sound-absorbing board. By setting the side cloth, the top cloth and the bottom cloth, the elastic sound-absorbing substrate can be wrapped in all directions. Since the side cloth, the top cloth and the bottom cloth are all made of elastic materials and have high elasticity, the service life of the sound-absorbing board can be increased and the sound absorption effect of the sound-absorbing board can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0016] Among them: 1 is an elastic sound-absorbing substrate; 2 is a side cloth; 3 is a top cloth; 4 is a bottom cloth; 5 is a hollow opening. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 and 2 The utility model discloses an elastic sound-absorbing board, comprising:

[0019] Elastic sound-absorbing substrate 1; in the present embodiment, the elastic sound-absorbing substrate 1 is used for sound absorption and is made of sound-absorbing material, such as polyester fiberboard, GPC sound-absorbing board, etc. The elastic sound-absorbing substrate 1 is made into a rectangular structure by laser cutting, engraving machine, resonance knife cutting, woodworking knife and table saw and other tools.

[0020] Side cloth 2, multiple side cloths 2 are provided, and the multiple side cloths 2 are connected to each other and wrapped around the side of the elastic sound-absorbing substrate 1; top cloth 3, top cloth 3 covers the top of the elastic sound-absorbing board, and the bottom surface of the top cloth 3 is connected to the top of the side cloth 2; bottom cloth 4, bottom cloth 4 is provided on the bottom surface of the elastic sound-absorbing board, and the top edge of the bottom cloth 4 is connected to the bottom of the side panel; in this embodiment, the side cloth 2, the bottom cloth 4 and the top cloth 3 are all made of materials with certain flexibility such as cloth, artificial leather, genuine leather, glass fiber cloth, carbon fiber cloth, etc.

[0021] The side with the hollow opening 5 is the back of the elastic sound-absorbing board, and the top cloth 3 is the front of the elastic sound-absorbing substrate 1.
