Abstract
The utility model discloses an acoustic door of an anechoic room. The acoustic door comprises sound-absorbing wedges arranged on the inner side of the acoustic door, wherein the acoustic door is mounted on one side of an acoustic wall of the anechoic room. When the acoustic door is inwards opened, the sound-absorbing wedges on the inner side of the acoustic door are mutually matched with the sound-absorbing wedges, corresponding to the acoustic door, on the acoustic wall. Therefore, when the acoustic door is opened, the acoustic door can be prevented from colliding with a test table in the anechoic room, and the maximum in and out space can be ensured.
Description
Technical field
The utility model relates to a kind of anechoic chamber soundproof door.
Background technology
Anechoic chamber is a kind of sound measurement environment, for reaching preferably measurement effect, all needs to be covered with wedge, so that each face can absorption of noise in anechoic chamber on all sound-proof wall body.Therefore, the inner side of anechoic chamber's soundproof door also needs to be provided with sound-absorbing wedge.In the prior art, the location comparison of most of soundproof doors is placed in the middle, if the volume of anechoic chamber is smaller, and the testboard of inside, anechoic chamber is larger, when soundproof door is opened, because the rotary motion trace of door is curved, can take space greatly, soundproof door just easy and testboard bumps.
Utility model content
The purpose of this utility model is for above-mentioned defect of the prior art, and a kind of follow-on anechoic chamber soundproof door is provided, and it can guarantee to have maximum turnover space can avoid testboard again simultaneously.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme: a kind of anechoic chamber soundproof door, comprise the sound-absorbing wedge that is arranged on described soundproof door inner side, it is characterized in that: described soundproof door is arranged on a side of the sound-proof wall body of anechoic chamber, when described soundproof door is inwardly opened, the sound-absorbing wedge corresponding to described soundproof door position on the sound-absorbing wedge of described soundproof door inner side and sound-proof wall body agrees with mutually.
In addition, the utility model also provides following attached technical scheme:
Described sound-absorbing wedge comprises base portion and the tip being connected with base portion, and the tip shapes corresponding to the sound-absorbing wedge of soundproof door position on the sound-absorbing wedge of described soundproof door inner side and described sound-proof wall body is all triangular prism.
Interlaced corresponding to the sound-absorbing wedge of soundproof door position on the sound-absorbing wedge of described soundproof door inner side and described sound-proof wall body, and the tip of each sound-absorbing wedge is level and arranges.
Than prior art, advantage of the present utility model is: this anechoic chamber's soundproof door is arranged on a side of the sound-proof wall body of anechoic chamber, when described soundproof door is inwardly opened, the sound-absorbing wedge corresponding to described soundproof door position on the sound-absorbing wedge of described soundproof door inner side and sound-proof wall body agrees with mutually.So, when soundproof door is opened, can avoid the testboard of inside, anechoic chamber, and can guarantee there is maximum turnover space.
Accompanying drawing explanation
Fig. 1 is the anechoic chamber's sectional view corresponding to the utility model preferred embodiment.
Fig. 2 is the partial enlarged drawing when the door opening state corresponding to anechoic chamber's soundproof door of 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.
See figures.1.and.2, corresponding to the anechoic chamber of the utility model preferred embodiment, it is mainly used in acoustic measurement.This anechoic chamber comprises testboard 2, sound-proof wall body 3, is arranged on the soundproof door 4 in sound-proof wall body 3 and is arranged on soundproof door 4 inner sides and sound-absorbing wedge 5a, the 5b of sound-proof wall body 3 inner sides, and wherein the shape of sound-absorbing wedge 5a and sound-absorbing wedge 5b is roughly the same.
Particularly, above-mentioned soundproof door 4 is arranged on a side of sound-proof wall body 3, and, near the corner of sound-proof wall body 3, soundproof door 4 is fixedly connected by loose-leaf (not shown) and sound-proof wall body 3.A plurality of sound-absorbing wedge 5a are evenly installed in the inner side of soundproof door 4, and wherein sound-absorbing wedge 5a comprises base portion 9 and tip 10, and wherein the optimum shape of tip 10 is triangular prism, and the tip 10 of each sound-absorbing wedge 5a is level and arranges.When soundproof door 4 is opened, on sound-proof wall body 3, there is a sound-proof wall body 3 ' relative with soundproof door 4, the inner side of sound-proof wall body 3 ' is evenly provided with sound-absorbing wedge 5b, and the installation site of sound-absorbing wedge 5b and sound-absorbing wedge 5a is interlaced.
Open the inside of the unfolding mode Shi Xiang anechoic chamber of soundproof door 4, and it has a movement locus, and this movement locus is camber line a.Its mean camber line a and testboard 2 do not have joining, represent that soundproof door 4 and testboard 2 do not bump.Due to the sound-absorbing wedge 5a on soundproof door 4 and the sound-absorbing wedge 5b mutual dislocation on sound-proof wall body 3 ', so it can mutually agree with and not bump.Tip due to sound-absorbing wedge 5a, 5b is triangular prism again, so its compatible degree is high, makes soundproof door 4 open scope maximum, has maximum turnover space.
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.
