Abstract
The utility model discloses a novel sound absorption board, which is a polygonal board, a soundproofing material is filled in the middle of the board, grooves are formed in one side of the board, concave holes are formed in the other side of the board, the bottoms of the grooves of the board are communicated with the concave holes of the board, the soundproofing material is a cotton-like material, the grooves in the one side of the board are mutually parallel at equal intervals, and the positions of the concave holes in the other side of the board correspond to the positions of the grooves in the one side of the board. By the sound absorption board with the technical scheme, the sound absorption effects of different frequency bands can be changed by changing the widths and the shapes of the grooves in the one side of the board and the diameters and the depths of the concave holes in the other side of the board.
Description
Technical field
The utility model relates to a kind of finishing material, and especially a kind of front has groove, and the back side is provided with the novel acoustical board of shrinkage pool.
Background technology
Processing method to noise in decorating now mainly contains: 1. the sound control glass window is installed.So-called soundproof window separates sound with two-layer window exactly.The slit of every layer of window is all tried one's best stifled tight, and this method is applicable to the place that all have noise jamming.In addition, you also can use double-layer glass, and the soundproof effect of this novel glass is also relatively good.2. steel casement door sound insulation is installed, and zinc-plated steel casement door middle level is separated with air, and the sound of indoor and outdoors all is difficult to transmit open.In addition, steel casement door can't make a noise when colliding with the door body with the glue limit; 3. the multipurpose cloth skill is decorated and soft decoration, and the sound absorption of cloth art product is well-known, also is way comparatively commonly used so use cloth art to abate the noise.Test shows, the fabric that dangles and the fabric of tiling, and its sound absorption is the same, so as long as you just can play sound-absorbing effect at indoor use cloth art product.And in numerous cloth art products, the most important with the deadening of curtain.4. note the sealing between the indoor difference in functionality room, and wall should not be too smooth.Wall is too smooth, and any sound all can produce and echo, thereby can increase the volume of noise.Therefore, you can use sound-absorbing effects such as wallpaper ornament materials preferably, also can adopt finishing means such as " Soft Rolls ".In addition, you also can utilize ornament materials such as Art Stone, and wall surface is made more coarse, make sound wave produce repeatedly refraction, thereby weaken noise.You it is also conceivable that and hang some pictures on the wall, not only can decorate but also can reduce noise; What use was maximum now absorbs noise with wooden furniture exactly, and wood fibre has porosity, can absorb noise.But the sheet material of selling on the market now seldom has the effect of eliminating noise mostly.
Summary of the invention
To above-mentioned deficiency, the utility model provides a kind of novel acoustical board.
For solving the problems of the technologies described above, the technical scheme of the utility model is a kind of novel acoustical board, and described acoustical board is a polygon sheet material; Fill the noise elimination material in the middle of the sheet material; The one side of sheet material is provided with groove, and the another side of sheet material is provided with shrinkage pool, and the bottom portion of groove of sheet material is communicated with the shrinkage pool of sheet material.
Described noise elimination material is cotton type material.
A plurality of grooves of the one side of described sheet material are parallel to each other and spacing equates.
A plurality of shrinkage pools of the one side of described sheet material, the bottom of positive a plurality of grooves of the corresponding sheet material in its position is provided with.
Through technique scheme, the beneficial effect of the utility model is: acoustical board is compared with traditional damping material, and its basic principle is different, can reach more desirable acoustics.Through groove width and the flute profile that changes positive a plurality of grooves of sheet material and the diameter and the degree of depth that changes sheet material meal with wine back side shrinkage pool, can change sound-absorbing effect to different frequency bands.
Description of drawings
Fig. 1 is the utility model overall structure sketch map.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified:
As shown in Figure 1; A kind of novel acoustical board of the utility model is a square sheet material 2, is filled with sponge material in the middle of the sheet material 2, and the front of sheet material 2 is provided with a plurality of grooves 3; The back side of sheet material 2 is provided with a plurality of shrinkage pools 5, and sheet material 2 positive groove 3 bottoms are communicated with the shrinkage pool 5 at sheet material 2 back sides.One side of sheet material is provided with tenon 1.The opposite side of sheet material is provided with tongue-and-groove 4.Sheet material 2 a plurality of positive grooves 3 are parallel to each other and spacing equates.A plurality of shrinkage pools 5 at sheet material 2 back sides, the bottom of corresponding sheet material 2 positive a plurality of grooves 3 in its position is provided with.
Claims (4)
1. novel acoustical board, it is characterized in that: described acoustical board is a polygon sheet material, fills the noise elimination material in the middle of the sheet material, and the one side of sheet material is provided with groove, and the another side of sheet material is provided with shrinkage pool, and the bottom portion of groove of sheet material is communicated with the shrinkage pool of sheet material.
2. novel acoustical board according to claim 1 is characterized in that: described noise elimination material is cotton type material.
