Preferably, a pair of said base extension planes are base planes, and said metal plate includes an outer surface parallel to said base planes and side transition portions connecting said outer surface and said projections.

Preferably, the side transition part and the base surface form an included angle of 30-60 degrees.

Preferably, the outer surface of the metal plate is an uneven curved surface.

Preferably, the base is provided with a plurality of mounting holes.

Preferably, the sound attenuation material is glass wool.

The utility model also provides a sound absorption unit, it is including a plurality of sound absorption wall decorative board and a plurality of fastener, adjacent the basal portion of decorative board overlap each other, the end of fastener pass two the basal portion link to each other with the wall body.

Compared with the prior art, the utility model have following advantage: the utility model discloses a partial surface is outside protruding, can effectively increase noise elimination area of contact to play better noise cancelling effect.

Detailed Description

For the purpose of explaining the technical content, the structural features, the achieved objects and the effects of the invention in detail, the following detailed description is given with reference to the accompanying drawings, wherein the "up" and "down" positional relationships in the present specification correspond to the up and down directions in the accompanying drawing 1,

the embodiment provides a sound absorption wall decorative board and sound absorption unit, and this sound absorption wall decorative board is applicable to indoor decoration such as recording room, audio-visual room etc. can provide good amortization sound absorption effect. Referring to fig. 1 and 2, the sound-absorbing wall panel includes: the fireproof and waterproof sound-absorbing plate comprises a metal plate 1 positioned on the outer layer, a fireproof and waterproof protective layer 2 arranged on the inner layer of the metal plate 1, and a sound-absorbing material 3 filled on the inner side of the fireproof and waterproof protective layer 2.

Specifically, the metal plate 1 includes a pair of base portions 12, 13 for connecting adjacent decorative panels and wall surfaces, and a protruding portion 11 protruding outward from the base portions. Wherein, the edges of the first base part 12 and the second base part 13 extend outwards respectively, and the first base part 12, the second base part 13 and the bulge part 11 form a structure which is approximately shaped like a Chinese character 'ji'. The first base 12 and the second base 13 are parallel to the boss 11, the first base 12 is connected with the boss 11 through a left transition portion 14, the boss 11 is connected with the second base 13 through a right transition portion 15, and the extension planes of the first base 12 and the second base 13 are used as base planes which are used for being attached to supporting surfaces such as walls or ceilings. The first base 12 and the second base 13 are both provided with mounting holes for fixing the decorative plate on the supporting surface.

Optionally, the outer surface of the metal plate 1 is an uneven curved surface, so that the sound wave reflection directions are more various, and a better silencing effect is achieved.

In addition, in the embodiment, the side transition part and the base surface form an included angle of 30-60 degrees, so that the outer surface of the decorative plate and the noise elimination contact area can be further increased.

The sound-deadening material 3 is accommodated in the boss 11, and the sound-deadening material 3 may be glass wool, sponge, foam, or the like. The metal plate is also provided with a plurality of air holes 16.

Fig. 3 is a schematic view of a sound absorption unit formed by a plurality of sound absorption wall surface decorative boards, and it can be seen from the figure that the sound absorption unit comprises a plurality of sound absorption wall surface decorative boards 10 and a plurality of screws 20, the bases of two adjacent decorative boards are overlapped and connected with each other through the screws 20, and the tail ends of the screws 20 penetrate through the two bases to be connected with a wall body. As can be seen from the figure, the sound absorption unit can form a continuous wavy surface on a support such as a wall, and the base, the side transition part and the bulge part can be effective in silencing contact area, so that the sound absorption unit can have better silencing effect.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the foregoing description only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims, specification, and equivalents thereof.
