Abstract
The utility model discloses a sound-absorbing wedge which comprises a base part and a pointed part connected with the base part, wherein sound-absorbing boards are mounted on surfaces of the base part and the pointed part; and the sound-absorbing boards are made of polyester fiber materials, and a plurality of through holes are uniformly formed in the sound-absorbing boards. The polyester fiber materials have a number of micropores, the sound-absorbing boards have good sound-absorbing effects, and the through holes are formed in the surfaces of the sound-absorbing boards, so that the noise reflection of the improved sound-absorbing wedge is reduced, and compared with a metal wedge, the noise absorptivity is improved by at least 20%.
Description
Technical field
The utility model relates to a kind of sound-absorbing wedge.
Background technology
Sound-absorbing wedge is a kind of important composition parts in acoustics audiometric room, and it is mainly used in absorbing noise.Sound-absorbing wedge is of a great variety, and wherein metal wedge is that the most frequently used a kind of, traditional metal wedge adopts punched steel plate as the surface of wedge, and at the inner acoustical cotton of filling of wedge, wherein the most frequently used acoustical cotton is 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 the punched steel plate on metal wedge surface also exists puncherless part, and be exactly that the reflection of sound easily occurs this part, affected the performance of absorption of sound, cause acoustic absorptivity variation.
Utility model content
The purpose of this utility model is for above-mentioned defect of the prior art, and a kind of follow-on sound-absorbing wedge is provided.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme: a kind of sound-absorbing wedge, comprise base portion and the tip being 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 utility model also provides following attached technical scheme:
Described abatvoix is by Polyester Fibers compression forming.
The percent opening of described abatvoix is at least 50%.
Glass fiber acoustical cotton is installed in described base portion and tip, and described acoustical cotton is by abatvoix housing.
Than prior art, advantage of the present utility model 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 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, noise absorption rate has improved at least 20%.
Accompanying drawing explanation
Fig. 1 is the sound-absorbing wedge stereogram corresponding to the utility model preferred embodiment.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
With reference to Fig. 1, corresponding to the sound-absorbing wedge of the utility model preferred embodiment, it is mainly used in absorbing noise.Sound-absorbing wedge 1 comprises base portion 3 and the tip 4 being connected with base portion 3.Particularly, the skeleton of sound-absorbing wedge 1 is welded by round steel, and acoustical cotton (not shown) is filled by portion within it, and the material of acoustical cotton is glass fiber acoustical cotton in the present embodiment.In order to prevent acoustical cotton leakage, contaminated environment need to be installed abatvoix 6 on the surface of base portion 3 and tip 4, in order to 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 is on sound-absorbing wedge 1 time, most of can entering in acoustical cotton by the perforation 8 on abatvoix 6.Owing to making the polyester fiber of abatvoix 6 itself, be a kind ofly to there is very microporous material again, so also there is fraction noise to be absorbed by abatvoix 6, certainly also have fraction to be reflected by abatvoix 6.Known through test, the acoustic absorptivity of sound-absorbing wedge 1 has improved at least 20% compared with metal wedge.
It is to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
Claims (4)
1. a sound-absorbing wedge, comprises base portion and the tip being 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, is characterized in that: described abatvoix is by Polyester Fibers compression forming.
3. sound-absorbing wedge according to claim 1, is characterized in that: the percent opening of described abatvoix is at least 50%.
