Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The ultra-microporous acoustic sound-absorbing board shown in fig. 1 and 2 sequentially comprises a surface layer 1, a base layer 2 and a bottom layer 3 from top to bottom, wherein the surface layer 1 and the bottom layer 3 are respectively attached and fixed on two sides of the base layer 2; a plurality of circular through holes 21 are formed in the base layer 2, and ultramicropores are densely distributed on the surface layer 1; the ultramicropores on the surface layer 1 falling within the outer contour range of the circular through holes 21 are communicated with the corresponding circular through holes 21; the bottom layer 3 is made of sound-absorbing material. The thickness of base layer 2 is obviously thicker than top layer 1 and bottom layer 3 for every circular through-hole 21 can form great resonance sound chamber with top layer 1 and bottom layer 3, on one hand through the sound absorption of bottom layer 3, on the other hand through the sound wave produce resonance effect in resonance sound chamber and make the energy of sound wave clear up. In order to make the cavity resonance sound absorption effect more effective, the diameter value of the circular through hole 21 is at least one order of magnitude higher than that of the ultra-micro hole.

Preferably, all of said ultra-micropores are uniformly distributed on said surface layer 1; the diameter of the ultramicropore is 0.5mm, and the center distance between adjacent ultramicropores is 2.2 mm. The diameter of ultramicropore and hole centre-to-centre spacing all are very little, only have been close to and just can see, not only can keep the integrality of top layer 1 material for decorative effect is good, can make the dust can't pierce through top layer 1 moreover and get into circular through-hole 21, prevents that the dust from piling up the influence sound absorbing effect, maintains sound absorbing performance commonly used.

Further, the base layer 2 is made of flame retardant materials, so that the ultra-microporous acoustic sound absorption plate can also play a role in fire prevention, and the safety in use in public places is ensured. Specifically, the base layer 2 is made of a flame-retardant environment-friendly high-density board (HDF board) or a non-combustible environment-friendly inorganic composite board.

The surface layer 1 is made of natural wood veneer or HPL (high pressure polyethylene) plate, so that the ultra-microporous acoustic sound-absorbing plate is attractive in appearance and good in decorative effect, and the surface texture of the surface layer can effectively cover the ultra-microporous acoustic sound-absorbing plate visually, so that the visual sense has a sense of unity.

The bottom layer 3 is made of sound absorption paper.

The utility model discloses an surpass ultra-micropore acoustics abatvoix is through setting up circular through-hole and setting up the super micropore with circular through-hole intercommunication in the basic unit to but the bottom that combines the sound absorption has formed scientific cavity resonance sound absorption structure, makes sound can be effectively absorbed after surpassing the micropore entering circular through-hole, and the absorption effect is good, and simple structure, and is with low costs.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
