Abstract
The invention discloses a sound-absorbing wedge which comprises a base part and a tip part connected with the base part, wherein sound-absorbing boards are installed at the surfaces of the base part and the tip part and are made of a polyester fiber material, and a plurality of through holes are uniformly formed in the sound-absorbing boards. As polyester fiber is a material with multiple tiny holes, the sound-absorbing boards have a good sound-absorbing effect. Moreover, the through holes are formed in the surfaces of the sound-absorbing boards, so that the improved sound-absorbing wedge reduces noise reflection. The noise absorption rate of the sound-absorbing wedge, compared with a metal wedge, is increased by at least 20 percent.
Description
Technical field
The present invention relates to a kind of sound-absorbing wedge.
Background technology
The sound-absorbing wedge is a kind of important composition parts in the acoustics audiometric room, and it is mainly used in absorbing noise.The sound-absorbing wedge is of a great variety, and wherein the metal wedge is that the most frequently used a kind of, traditional metal wedge adopts the surface of punched steel plate as wedge, and, at the inner acoustical cotton of filling of wedge, wherein the most frequently used acoustical cotton is the glass fiber acoustical cotton.The main feature of such metal wedge has outward appearance carefully and neatly attractive in appearance, steadiness is good, and the place at this metal wedge perforate surface, can well absorb sound, but because also there is puncherless part in the punched steel plate on metal wedge surface, and be exactly that the reflection of sound easily occurs this part, affected the performance of absorption of sound, cause the acoustic absorptivity variation.
Summary of the invention
The object of the invention is to for above-mentioned defect of the prior art, a kind of follow-on sound-absorbing wedge is provided.
For achieving the above object, the present invention has adopted following technical scheme: a kind of sound-absorbing wedge, comprise base portion and the tip be connected with base portion, it is characterized in that: abatvoix is installed on described base portion and surface, tip, and evenly distributed a plurality of perforation are made and be provided with on it to described abatvoix by Polyester Fibers.
In addition, the present invention also provides following attached technical scheme:
Described abatvoix is by the Polyester Fibers compression forming.
The percent opening of described abatvoix is at least 50%.
The glass fiber acoustical cotton is installed in described base portion and tip, and described acoustical cotton is by the abatvoix housing.
Than prior art, advantage of the present invention is: abatvoix is installed on the base portion of this sound-absorbing wedge and surface, tip, and evenly distributed a plurality of perforation are made and be provided with on it to abatvoix by Polyester Fibers.Because polyester fiber is a kind ofly to have very microporous material, so abatvoix has good sound-absorbing effect, add the abatvoix surface and be provided with perforation, so, this modified sound-absorbing wedge has reduced the reflection of noise, and with the contrast of metal wedge, the noise absorption rate has improved at least 20%.
The accompanying drawing explanation
Fig. 1 is the sound-absorbing wedge stereogram corresponding to preferred embodiment of the present invention.
The specific 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, corresponding to the sound-absorbing wedge of preferred embodiment of the present invention, it is mainly used in absorbing noise.Sound-absorbing wedge 1 comprises base portion 3 and the tip 4 be connected with base portion 3.Particularly, the skeleton of sound-absorbing wedge 1 is welded by round steel, and the acoustical cotton (not shown) is filled by section within it, and the material of acoustical cotton is the glass fiber acoustical cotton in the present embodiment.In order to prevent the acoustical cotton leakage, contaminated environment need to be installed abatvoix 6 on the surface of base portion 3 and tip 4, in order to the housing acoustical cotton.It is polyester fiber that the best of abatvoix 6 is made material, specifically by polyester fiber, is compressed into plate, and its surface arranges evenly distributed perforation 8, and percent opening is at least 50%.Because the end face of base portion 3 need to be fixed on the wall, so the end face of base portion 3 can not arrange perforation 8.
When noise transmission on sound-absorbing wedge 1 time, most of can entering in acoustical cotton by the perforation 8 on abatvoix 6.Because the polyester fiber of making abatvoix 6 itself is a kind ofly to have very microporous material, so also there is the fraction noise to be absorbed by abatvoix 6, certainly also there is fraction to be reflected by abatvoix 6 again.Known through test, the acoustic absorptivity of sound-absorbing wedge 1 has improved at least 20% than the metal wedge.
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 (4)
1. a sound-absorbing wedge, comprise base portion and the tip be connected with base portion, it is characterized in that: abatvoix is installed on described base portion and surface, tip, and evenly distributed a plurality of perforation are made and be provided with on it to described abatvoix by Polyester Fibers.
2. sound-absorbing wedge according to claim 1, it is characterized in that: described abatvoix is by the Polyester Fibers compression forming.
3. sound-absorbing wedge according to claim 1, it is characterized in that: the percent opening of described abatvoix is at least 50%.
4. sound-absorbing wedge according to claim 1, it is characterized in that: the glass fiber acoustical cotton is installed in described base portion and tip, and described acoustical cotton is by the abatvoix housing.
