Description
Technical Field
The utility model relates to a building material technical field, more specifically relate to a low frequency sound absorber.
Background
With the development of society, the requirements of people on the quality of life are higher and higher. A comfortable living and working environment becomes the most basic choice for people. Nowadays, noise pollution is almost ubiquitous, and environmental pollution control is a problem which needs to be solved urgently. Current sound absorbing materials can be divided into two main categories: inorganic fibrous materials and organic polymeric fibrous materials. The inorganic fiber material has the advantages of good sound absorption performance, light weight, non-combustibility, corrosion resistance, aging resistance and the like, so the inorganic fiber material is widely applied in the field of acoustics. However, it also has insurmountable disadvantages: the inorganic fiber material is brittle and is easy to break to cause pollution, stimulate the skin of a human body and easily cause permanent injury after being inhaled. The organic fiber material has good absorption capacity for middle and high frequency noise and wide application range. However, the organic fiber material has an unsatisfactory effect of absorbing low-frequency noise, and a considerable part of the organic fiber material can release harmful gas when meeting high temperature, thus harming human health. Therefore, the healthy, environment-friendly and light decorative material becomes the first choice of people.
Disclosure of Invention
The utility model aims at solving the defects of the prior art and providing a low-frequency sound absorber with simple structure, good sound absorption effect and good stability.
The utility model discloses an adopt following technical solution to realize above-mentioned purpose: the utility model provides a low frequency sound absorber which characterized in that, it includes from last decoration cloth layer, the cotton layer of hydrophobic environmental protection sound absorption, the aluminium foil layer that down sets gradually, and the outside on the cotton layer of hydrophobic environmental protection sound absorption is provided with the frame.
As a further explanation of the above scheme, the edge of the decorative cloth layer is fixed on the frame.
Furthermore, the aluminum foil layer is tightly attached to the bottom of the hydrophobic environment-friendly sound absorption cotton layer, and the edge of the aluminum foil layer is fixed on the frame.
Further, the frame comprises a vertical plate, an upper folded plate and a lower folded plate which are respectively arranged at the upper end and the lower end of the vertical plate, and the upper folded plate, the vertical plate and the lower folded plate are connected to form an embedded groove structure for containing the side end of the hydrophobic environment-friendly sound absorption cotton layer.
Furthermore, the side of the hydrophobic environment-friendly sound absorption cotton layer is provided with a convex edge corresponding to the caulking groove structure.
Furthermore, the upper folding plate, the vertical plate and the lower folding plate are of an integrally formed aluminum frame structure.
The utility model adopts the beneficial effect that above-mentioned technical solution can reach is:
the utility model discloses a from last decorative cloth layer, the cotton layer of hydrophobic environmental protection sound absorption, aluminium foil layer of down setting gradually to set up the frame in the outside on the cotton layer of hydrophobic environmental protection sound absorption, the bulk strength of reinforcing sound absorber, aluminium foil layer have good thermal-insulated and water-proof effects, combine to absorb low frequency noise with the cotton layer of hydrophobic environmental protection sound absorption.

Description of reference numerals: 1. the sound-absorbing decorative board comprises a decorative cloth layer 2, a hydrophobic environment-friendly sound-absorbing cotton layer 3, an aluminum foil layer 4, a frame 4-1, a vertical plate 4-2, an upper folded plate 4-3 and a lower folded plate.
Detailed Description
The technical solution is described in detail with reference to specific embodiments below.
As shown in fig. 1 and 2, the utility model relates to a low frequency sound absorber, it includes from last decoration cloth layer 1, the cotton layer 2 of hydrophobic environmental protection sound absorption, the aluminium foil layer 3 that down set gradually, and the outside on the cotton layer of hydrophobic environmental protection sound absorption is provided with frame 4. The edge of the decorative fabric layer is fixed on the frame, the aluminum foil layer is tightly attached to the bottom of the hydrophobic environment-friendly sound absorption cotton layer, and the edge of the aluminum foil layer is fixed on the frame.
Further, the frame 4 comprises a vertical plate 4-1, and an upper folded plate 4-2 and a lower folded plate 4-3 which are respectively arranged at the upper end and the lower end of the vertical plate, wherein the upper folded plate, the vertical plate and the lower folded plate are connected to form a caulking groove structure for accommodating the side end of the hydrophobic environment-friendly sound absorption cotton layer. The side on hydrophobic environmental protection sound absorption cotton layer is provided with the chimb that corresponds with the caulking groove structure. In this embodiment, the upper folding plate, the vertical plate and the lower folding plate are an integrally formed aluminum frame structure.
Compared with the prior art, the utility model, adopt from last down to set gradually decorate cloth layer, the cotton layer of hydrophobic environmental protection sound absorption, aluminium foil layer to set up the frame in the outside on the cotton layer of hydrophobic environmental protection sound absorption, the bulk strength of reinforcing sound absorber, aluminium foil layer have good thermal-insulated and water-proof effects, combine to absorb low frequency noise with the cotton layer of hydrophobic environmental protection sound absorption.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
