Abstract
The utility model provides a special high-sound absorption board for large places such as squares and the like, which has the advantages of reasonable structure and good sound attenuation effect and is convenient to process. The special high-sound absorption board provided by the utility model comprises a panel; multiple sound absorption holes are distributed on the panel; the diameters of the sound absorption holes are gradually increased along the panel from surface to inside; and an elastic sound attenuation layer is arranged on the back of the panel. In the utility model, the diameters of the sound absorption holes are gradually increased along the panel from surface to inside, and the noise enters from the sound absorption holes and is diffused in the inner cavities of the sound absorption holes; since the sound absorption holes have an inner horn shape, the reflected waves after diffusion are easily canceled out by resonance, and the sound attenuation effect is good; and one part of the sound wave enters the elastic sound attenuation layer which is of an elastic structure with many cellular gaps, and the sound waves are absorbed when transmitted in the gaps so as to realize an effect of completely absorbing and attenuating sound. The special high-sound absorption board provided by the utility model has the advantages of reasonable structure and good sound absorption effect, is convenient to process, and is suitable for large spaces such as squares, assembly halls and the like.
Description
Technical field
The utility model relates to a kind of sheet material, is specifically related to a kind of high-performance sound-absorbing sheet material that is specifically designed to large-scale places such as square.
Background technology
The square cultural activity receives the care support of various circles of society and the people's warm welcome, has produced great social influence, has become a widely known cultural grand occasion of city, enriches and enlivened the people's culture life.The square cultural activity has become the cultural activity that common people love, has been dissolved in the people's the daily life, bursts out unlimited vigor and vitality.Extensively carrying out of square cultural activity of a mass character makes entire society's atmosphere become positive, happy and auspicious, also promoted the flourishing and development of mass culture.Yet because effectively management of the movable shortage in square now, the resident living around the noise of its high-decibel is given has been brought tremendous influence.
As everyone knows; Noise not only can the ear-drum of harm people outside; All can produce negative influence to people's psychology, spirit, thus the people of long-term activity under noise, its physiology and all can receive serious injury psychologically; Be accompanied by development of science and technology, the plant equipment of all stereo sets, the vehicles, factory, the construction of building site etc. produces noise invariably.
Used on the market abatvoix mainly is to be made up of panel with a plurality of sound-absorption hole and the noise reduction rock wool that is positioned at the abatvoix rear side at present, and sound wave is absorbed by the noise reduction rock wool after getting into sound-absorption hole.When the penetration capacity of acoustic wave segment was strong, only the noise reduction rock wool can't absorb sound wave fully, and acoustic wave segment reflects away from sound-absorption hole through the reflection meeting, forms noise once again.
Summary of the invention
In order to overcome the deficiency of prior art, it is a kind of rational in infrastructure, easy to process that the utility model provides, the high-performance sound-absorbing sheet material that is specifically designed to large-scale places such as square of good muffling effect.
The utility model solves the technical scheme that its technical problem adopted:
The special-purpose high sound absorption qualities sheet material in a kind of square comprises panel, is distributed with several sound-absorption hole on the said panel, and the diameter of said sound-absorption hole becomes big along panel by table gradually to the lining, and the back side of said panel is provided with elasticity noise reduction layer.
In the utility model, said elasticity noise reduction layer is the noise reduction rock wool.
In the utility model, it is conical that said sound-absorption hole is.
In the utility model, said sound-absorption hole criss-cross arrangement is also formed pattern.
The beneficial effect of the utility model is: the diameter of the sound-absorption hole of the utility model becomes big along panel by table gradually to the lining, and noise carries out diffusion from the sound-absorption hole entering and at the sound-absorption hole inner chamber, because sound-absorption hole is the inside trumpet shape; Each back wave after diffusion is easy to generate resonance and offsets, and good muffling effect also has acoustic wave segment to get into elasticity noise reduction layer; Elasticity noise reduction layer is an elastic construction; And many cellular gaps are arranged on it, and sound wave is absorbed when in the gap, propagating, thereby reaches complete sound-absorbing erasure effect; The utility model is rational in infrastructure, easy to process, sound-absorbing effect is good, is applicable to large-scale occasions such as square, assembly hall.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is A-A direction sectional view of Fig. 1;
Fig. 3 is the structural representation of another embodiment.
The specific embodiment
With reference to Fig. 1, Fig. 2; What present embodiment provided is a kind of simple in structure, easy to process, the high-performance sound-absorbing sheet material that is specifically designed to large-scale places such as square of good muffling effect; Comprise panel 1; Be distributed with several sound-absorption hole 2 on the said panel 1, the diameter of said sound-absorption hole 2 becomes big along panel by table gradually to the lining, and the back side of said panel 1 is provided with elasticity noise reduction layer 3.
As preferred embodiment, said elasticity noise reduction layer 3 is the noise reduction rock wool, owing in the noise reduction rock wool many cellular gaps are arranged, sound wave is done repeatedly collision in the gap after, changes frequency and weakens energy, with wave absorption, reaches the effect of sound-absorbing.
Further, in this enforcement, it is conical that said sound-absorption hole 2 is, because easy to process, the good looking appearance of circular cone can be used for large-scale production and sale.Certainly, the also side's of can be taper or triangular pyramidal of sound-absorption hole 2 has identical technique effect herein, is its equivalent technology scheme.
Institute further for the profile that makes sheet material is more attractive in appearance, is fit to the effect of furring, states sound-absorption hole 2 criss-cross arrangements and forms pattern, and pattern can be adjusted according to the demand of present construction.At present embodiment, said pattern is a triangle.With reference to Fig. 3, this pattern is a square.
The above is merely the preferential embodiment of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the utility model.
