Abstract
The utility model relates to a sound absorbing board with big and small holes. The sound absorbing board with big and small holes is a positive quadrangular board 4, wherein the front face of the board 4 a plurality of small holes 3, the back face of the board 4 is provided with a plurality of big holes 2, and the small holes of the front face of the board 4 and the big holes 2 of the back face of the board 4 form one-to-one correspondence and communication; the back face of the board 4 is provided with a thin sound absorbing blanket 1; the longitudinal spacing and the transverse spacing of the small holes 3 of the front face and the big holes 2 of the back face of the board 4 are equal. The board 4 is made of wood, and can also be a pollution-free synthetic board, such as a medium fiber composite board. The diameters and the depth of the small holes of the front face of the board 4 and the big holes 2 of the back face of the board 4 are changed so that the sound absorbing effects of different frequency bands can be changed, therefore the utility model achieves an ideal sound effect. Compared with the traditional sound-absorbing materials, the utility model can achieve the ideal sound effect, and can be widely used for television stations, movie theaters, music halls, crazy sounding houses, etc.
Description
Technical field
The utility model relates to finishing material, and especially a kind of front has aperture, and the back side is provided with macropore, and the acoustical board of big aperture connection.
Background technology
Timber is the indoor hardware fitting that people like, but the plank on plane can produce complicated reflection to sound, influences acoustics.So to the demanding occasion of acoustics, traditional way generally is to carry out sound-absorbing or sound insulation with the glass wool goods, its shortcoming is that sound-absorbing effect is not ideal enough, and unfavorable environmental protection.
Summary of the invention
The purpose of this utility model is at the demanding occasion of acoustics, carries out sound-absorbing or sound insulation with the glass wool goods, and effect is not ideal enough, and the problem of unfavorable environmental protection provides a kind of sound insulation, and sound-absorbing effect is good, environmental, elegant in appearance acoustical board with big aperture.
Acoustical board with big aperture described in the utility model is a square sheet material.The front of sheet material is provided with a plurality of apertures.The back side of sheet material is provided with a plurality of macropores.The macropore at the aperture in sheet material front and the sheet material back side is corresponding one by one and be communicated with.
The back side of sheet material is provided with the thin blanket of sound absorption.
A plurality of macropore longitudinal pitches at a plurality of apertures in sheet material front and the back side equate.
A plurality of macropore horizontal spacings at a plurality of apertures in sheet material front and the back side equate.
Said sheet material is timber, also can be free of contamination synthetic plate, as middle fiber composite plate.
Acoustical board with big aperture described in the utility model is compared with traditional damping material, and its basic principle difference can reach more desirable acoustics.By changing the positive a plurality of apertures of sheet material and changing the diameter and the degree of depth of the back side each macropore of plural number of sheet material, can change sound-absorbing effect, thereby reach desirable acoustics different frequency bands.Excellent decoration effect that the utility model also has.The utility model can be widely used in occasions such as TV station, cinema, concert hall, fever sound equipment room.
Description of drawings
Fig. 1 is the constructional drawing that the utlity model has the acoustical board of big aperture;
Fig. 2 is the front view that the utlity model has the acoustical board of big aperture;
Fig. 3 is the rear elevation that the utlity model has the acoustical board of big aperture;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1-Figure 3, the acoustical board with big aperture described in the utility model is a square sheet material 4.The front of sheet material 4 is provided with a plurality of apertures 3.The back side of sheet material 4 is provided with a plurality of macropores 2.The macropore 2 at the aperture 3 in sheet material 4 fronts and sheet material 4 back sides is corresponding one by one and be communicated with.
The back side of sheet material 4 is provided with the thin blanket 1 of sound absorption.
A plurality of macropores 2 longitudinal pitches at a plurality of apertures 3 in sheet material 4 fronts and the back side equate.
A plurality of macropores 2 horizontal spacings at a plurality of apertures 3 in sheet material 4 fronts and the back side equate.
Said sheet material 4 is timber, also can be free of contamination synthetic plate, as middle fiber composite plate.
