Abstract
The utility model discloses a sound absorption wedge for an anechoic chamber. The anechoic chamber comprises a sound insulation wall body and the sound absorption wedge arranged on the sound insulation wall body, wherein the sound absorption wedge comprises a vertical part and a top part connected with the vertical part; and a joint between the top part and the vertical part is in a circular arc shape. The vertical part and the top part are connected in a smooth transition mode, so that the uncertainty and the irregularity of the sound absorption wedge on sound reflection are improved, and the sound absorption performance of the anechoic chamber is improved.
Description
Technical field
The utility model relates to a kind of sound-absorbing wedge of anechoic chamber.
Background technology
The anechoic chamber is widely used in the acoustic measurement on the products such as machinery, electronics and Medical Devices at present, and it can be used as medical audiometry diagnosis room, language recording room, Shop floor control chamber or noise testing chamber.Therefore, higher to the requirement of anechoic chamber's sound absorption qualities.
With reference to Fig. 2, existing anechoic chamber comprises sound-proof wall body 10 and is installed in the sound-absorbing wedge 12 of sound-proof wall body 10 inboards.And rectangular design is adopted in overall structure in the cross section of sound-absorbing wedge 12, namely forms a right angle between the top 14 of this sound-absorbing wedge and its vertical portion 16, thereby causes the uncertainty of sound reflection to increase, and causes the irregular reflection of sound.So, be necessary to provide this improved.
The utility model content
The purpose of this utility model is for defects of the prior art, and a kind of sound-absorbing wedge of improved anechoic chamber is provided, and it can improve the sound absorption qualities of anechoic chamber.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: described anechoic chamber comprises sound-proof wall body and the sound-absorbing wedge that is installed on the described sound-proof wall body, described sound-absorbing wedge comprises vertical portion and the top that is connected with described vertical portion, it is characterized in that: the junction between described top and the described vertical portion is circular-arc.
In addition, the utility model also provides following attached technical scheme:
Described top is circular-arc.
The sound-absorbing wedge global sections of described anechoic chamber is inverse u shape.
The sound-absorbing wedge of described anechoic chamber is made by damping material.
Than prior art, the utility model has the advantage of: the junction between its top of sound-absorbing wedge of the present utility model and the vertical portion is circular arc, thereby reach a level and smooth transition, improved its uncertainty and scrambling to sound reflection, improved the sound absorption qualities of sound attenuation room.
Description of drawings
Fig. 1 is the schematic cross-section after the sound-absorbing wedge corresponding to the anechoic chamber of the utility model preferred embodiment is installed on sound-proof wall body.
Fig. 2 is the schematic cross-section after the sound-absorbing wedge of anechoic chamber of the prior art is installed on sound-proof wall body.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical solutions of the utility model are done further nonrestrictive detailed description.
With reference to Fig. 1, comprise sound-proof wall body 1 and be installed on sound-absorbing wedge 3 on the described sound-proof wall body 1 corresponding to the anechoic chamber of the utility model preferred embodiment.The cross section of above-mentioned sound-proof wall body 1 is rectangular design, and described sound-absorbing wedge 3 is installed on the inwall 7 of sound-proof wall body 1.
Described sound-absorbing wedge 3 is made by centrifugally glass-wool or other damping materials, comprises vertical portion 32 and the top 34 that is connected with described vertical portion 32.Junction 36 between described top 34 and the described vertical portion 32 is circular-arc.Simultaneously, described top 34 also is circular-arc, the sound-absorbing wedge 3 of described like this anechoic chamber is inverse u shape at global sections, that is reach a level and smooth transition being connected between its vertical portion 32 and the top 34, thereby improved its uncertainty and scrambling to sound reflection, improved the sound absorption qualities of sound attenuation room.
It is to be noted; above-mentioned preferred embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, 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, and all should be encompassed within the protection domain of the present utility model.
