Abstract
A sound absorption plate comprises a frame and an end cap, wherein the frame comprises a side wall A and a side wall B, the side wall A is provided with sound through holes, polyester fiber cotton plates of the sound through holes with different densities are arranged in the frame at intervals, and the densities of the sound through holes in the polyester fiber cotton plates are sequentially reduced from the side wall A to the side wall B. By means of design of inner oscillation cavities, sound is gradually absorbed by the polyester fiber cotton plates in the oscillation cavities during oscillation, besides, the sound is gradually transferred from high-density polyester fiber cotton plates to low-density polyester fiber cotton plates, and accordingly, sound absorption work can be distributed in different oscillation cavities and the sound absorption effect is better.
Description
Technical field
The present invention relates to a kind of sound arrester, particularly a kind of abatvoix.
Background technology
In present house decoration, people more and more note the sound insulation problem between indoor and outdoor, this involves has a rest and the problem such as privacy, and the such as house of contiguous highway can be subject to highway and to get on the car the impact of noise, and what the resident family on contiguous square can be subject to that square waves bothering.
Summary of the invention
In order to a more quiet indoor environment can be set up in indoor, the invention provides a kind of abatvoix.
Concrete technical scheme is:
A kind of abatvoix, comprise framework and capping, described framework comprises sidewall A and sidewall B, sidewall A offers logical sound through hole, be arranged at intervals with the cotton plate of polyester fiber that there is different densities and lead to sound through hole in framework, and on the cotton plate of set polyester fiber, logical sound via densities reduces to sidewall B successively from sidewall A.
Further, framework and capping are fixed together by tack coat.
Further, vibration chamber is provided with between the cotton plate of polyester fiber that described different densities leads to sound through hole.
The present invention adopts inner vibration chamber design, crossing in layer that sound is shaken in vibration chamber is absorbed by the cotton plate of polyester fiber gradually, and sound transmits from containing polyester of high density fiber cotton plate gradually to containing the cotton plate of low-density polyester fiber, sound-absorbing work can be assigned in different vibration chambeies, and sound-absorbing effect is more perfect.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Detailed description of the invention
As can see from Figure 1, a kind of abatvoix, comprise framework 1 and capping 3, described framework comprises sidewall A and sidewall B, sidewall A offers continuant orifice 4, be arranged at intervals with the cotton plate of polyester fiber that there is different densities and lead to sound through hole in framework 1, and on the cotton plate of set polyester fiber, logical sound via densities reduces to sidewall B successively from sidewall A.
In the present invention, the logical sound through hole containing higher density on the cotton plate 6 of polyester fiber, density is 100/m
2, the logical sound through hole containing intermediate density on the cotton plate 7 of polyester fiber, density is 60/m
2, containing less logical sound through hole on the cotton plate 8 of polyester fiber, density is 20/m
2.
Inside sidewall B, be fitted with the cotton plate of a closely knit polyester fiber, prevent sound from internally spreading further.
Framework 1 and capping 3 are fixed together by tack coat 2, and the present invention uses white emulsion binder.
Vibration chamber 10 is provided with between the cotton plate of polyester fiber that different densities leads to sound through hole.
The present invention adopts inner vibration chamber 10 to design, sound crossing in layer of concussion in vibration chamber 10 is absorbed by the cotton plate of polyester fiber gradually, and sound transmits from containing polyester of high density fiber cotton plate gradually to containing the cotton plate of low-density polyester fiber, sound-absorbing work can be assigned in different vibration chambeies 10, and sound-absorbing effect is more perfect.
Claims (3)
1. an abatvoix, it is characterized in that: comprise framework and capping, described framework comprises sidewall A and sidewall B, sidewall A offers logical sound through hole, be arranged at intervals with the cotton plate of polyester fiber that there is different densities and lead to sound through hole in framework, and on the cotton plate of set polyester fiber, logical sound via densities reduces to sidewall B successively from sidewall A.
2. a kind of abatvoix according to claim 1, is characterized in that: framework and capping are fixed together by tack coat.
