Abstract
The invention discloses an anechoic chamber which comprises a sound-insulation wall and a sound-absorption device. The sound-absorption device comprises sound-absorption cotton and sound-absorption cloth, the sound-absorption cotton is evenly installed at the inner side of the sound-insulation wall, and the sound-absorption cloth wraps the sound-absorption cotton. Due to the fact that sound-absorption cloth is low in sound reflection, the anechoic chamber has the better acoustic testing effect.
Description
Technical field
The present invention relates to a kind of silencer box.
Background technology
Silencer box is a kind of common acoustical testing environment, and its structure for the semianechoic room that approaches desirable free field is small and exquisite, and its audiometry effect is better.So this type of silencer box has met the restriction due to space, do not have condition to build the empty client's that partly eliminates the noise who approaches desirable free field requirement.And, in prior art, the outside of silencer box sound-proof wall body is steel plate, the inner acoustical cotton of filling, the internal layer surface is mesh plate.But because also there is imperforated part in mesh plate, and these puncherless parts have caused and the reflection of sound have affected acoustical testing just.
Summary of the invention
The object of the invention is to, for above-mentioned defect of the prior art, provides a kind of follow-on silencer box.
For achieving the above object, the present invention has adopted following technical scheme: a kind of silencer box, comprise sound-proof wall body and sound arrester, it is characterized in that: described sound arrester comprises acoustical cotton and sound-absorbing cloth, described acoustical cotton evenly is arranged on the inboard of described sound-proof wall body, and described sound-absorbing cloth wraps up described acoustical cotton.
In addition, the present invention also provides following attached technical scheme:
Described sound arrester also comprises press strip, and described press strip is arranged on the surrounding of described acoustical cotton and sound-absorbing cloth.
The inboard of described press strip and sound-proof wall body is fixedly connected.
Described press strip is connected with the inboard screw connecting mode that adopts of described sound-proof wall body.
Described press strip is connected with the inboard rivet connected mode that adopts of described sound-proof wall body.
Than prior art, advantage of the present invention is: the sound arrester in this silencer box comprises acoustical cotton and sound-absorbing cloth, and acoustical cotton evenly is arranged on the inboard of sound-proof wall body, sound-absorbing cloth parcel acoustical cotton.Because the sound reflection of sound-absorbing cloth is little, so this silencer box has good acoustical testing effect.
The accompanying drawing explanation
Fig. 1 is corresponding to the stereographic map of the silencer box of preferred embodiment of the present invention.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
With reference to Fig. 1, it is corresponding to the silencer box of preferred embodiment of the present invention, and it is mainly used in acoustical testing.It comprises sound-proof wall body 4 and sound arrester 6.Wherein, sound arrester 6 comprises acoustical cotton (not shown) and sound-absorbing cloth 7, and sound arrester 6 is fixedly connected on the inboard of sound-proof wall body 4 by press strip 12.
Particularly, acoustical cotton is arranged on the inboard of sound-proof wall body 4 equably, and sound-absorbing cloth 7 is installed outside acoustical cotton again, for wrapping up acoustical cotton, to prevent acoustical cotton, reveals and contaminated environment.In the surrounding of sound-absorbing cloth 7, press strip 12 is installed, press strip 12 can be connected by screw the inboard that mode or rivet connected mode are fixedly connected on sound-proof wall body 4.
Because the sound reflection of sound-absorbing cloth 7 is little, and use press strip 12 to make sound arrester 6 be fixedly connected on the inboard of sound-proof wall body 4, also make sound arrester 6 keep smooth simultaneously.So this modified silencer box is both artistic and practical, there is good acoustical testing effect.
It is pointed out that above-mentioned preferred embodiment is only explanation technical conceive of the present invention and characteristics, its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
Claims (5)
1. a silencer box, comprise sound-proof wall body and sound arrester, it is characterized in that: described sound arrester comprises acoustical cotton and sound-absorbing cloth, and described acoustical cotton evenly is arranged on the inboard of described sound-proof wall body, and described sound-absorbing cloth wraps up described acoustical cotton.
