Abstract
The utility model relates to a construction and decoration material, in particular to a sound-absorbing board. The sound-absorbing board comprises a baseplate; a plurality of first sound-absorbing holes and a plurality of second sound-absorbing holes are formed on two dies of the baseplate, respectively; the pore diameter of each first sound-absorbing hole is larger than that of each second sound-absorbing hole; the sound-absorbing holes are communicated with the second sound-absorbing holes; and the first sound-absorbing holes and the second sound-absorbing holes are arranged in a one-one correspondence manner. Compared with the prior art, when the sound-absorbing board is used, sound enters from the second sound-absorbing holes and is absorbed after being amplified by the first sound-absorbing holes; and the sound reflection is tiny, so that the utility model has good sound absorption effect.
Description
Technical field
The utility model relates to a kind of building and ornament materials, is meant a kind of abatvoix especially.
Background technology
In the prior art, in the demanding place of acoustics, such as occasions such as cinema, KTV, traditional way is to carry out sound-absorbing or sound insulation with the glass wool goods, and its shortcoming is that sound-absorbing is not ideal enough, and decorative effect is also relatively poor.
For this reason, people have proposed multiple solution.
CN2713035Y discloses a kind of " abatvoix with hole slot ", is a rectangle sheet material, and its front longitudinally is provided with a plurality of grooves and a plurality of fins, the alternate setting of groove and fin; The back side of rectangle sheet material longitudinally is provided with a plurality of shrinkage pools.The bottom of rectangle sheet material front longitudinal fluting offers vertical slit, and the bottom of slit is communicated with the shrinkage pool at the rectangle sheet material back side.Groove width and flute profile and the back side that changes rectangle sheet material longitudinally diameter and the degree of depth of shrinkage pool of this patent by changing positive a plurality of grooves of rectangle sheet material, can change sound-absorbing effect to a certain extent to different frequency bands, but it is very big to the sound-absorbing effect difference of different frequency bands with a kind of sheet material, and is also impracticable in actual the use.
CN2746023Y discloses a kind of abatvoix, formed by surface of steel plate layer and damping material inner cord bonding, the punching steel plate dashes equally distributed sound-absorbing aperture, and the sound absorber flitch can be the face glass that is wrapped with the glass cotton, its back side has aluminium foil again, and each layer is bonded to one successively.Though this patent has certain sound-absorbing effect, its sound-absorbing effect is unsatisfactory, and adopts surface of steel plate layer cost also higher.
CN2878557Y discloses a kind of " decoration acoustic panel ", and it comprises a substrate, in substrate front side guide groove is set, this guide groove bottom surface is wavy relief, this relief is provided with a plurality of perforation, and perforation communicates with the groove of substrate back, and the guide groove width is greater than groove width.This decoration acoustic panel manufacturing is comparatively complicated, and manufacturing cost is higher, and its decoration function is greater than sound absorption, and sound-absorbing effect is not good.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of abatvoix of excellent sound absorbing is provided.
The utility model adopts following technical scheme:
A kind of abatvoix, it comprises a substrate, the both sides of this substrate are respectively equipped with a plurality of first sound-absorption hole and a plurality of second sound-absorption hole, the aperture of this first sound-absorption hole is greater than the aperture of this second sound-absorption hole, and each first sound-absorption hole all is connected with one second sound-absorption hole, and this first sound-absorption hole becomes corresponding one by one setting with this second sound-absorption hole.
According to a better embodiment of the present utility model, the section of described first sound-absorption hole and described second sound-absorption hole is a rectangle.
According to a better embodiment of the present utility model, described substrate is pasted with a baffle blanket in the side that it is provided with described first sound-absorption hole.
The utility model in use, a side that is provided with second sound-absorption hole is positioned at the outside, a side that is provided with first sound-absorption hole is positioned at the inboard, sound sucks in second sound-absorption hole, be absorbed after first sound-absorption hole is amplified, sound reflection is minimum, makes to the utlity model has splendid sound-absorbing effect.
