Abstract
The utility model discloses a ventilation wedge of an anechoic chamber. The ventilation wedge is provided with a ventilation port and is characterized in that reinforcing steel bars are arranged inside the ventilation wedge, sound absorption materials are filled inside the ventilation wedge, sound absorption cloth is wrapped on the outside, and the ventilation wedge not only can absorb sound, but also achieves ventilation.
Description
Technical field
The utility model relates to a kind of ventilation wedge of anechoic chamber.
Background technology
Anechoic chamber, quiet room or silencer box (following take the anechoic chamber as example) are 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.In the anechoic chamber, sometimes need a compound ventilation air-changing device, like this, in inside, anechoic chamber ventilation opening need to be set.And one of Main Function of anechoic chamber is the space of formation internal freedom sound field, and namely section is without obvious reflection within it for sound, and the anechoic chamber is inner without obvious reflector.Therefore, be necessary to provide a kind of ventilation opening that can reduce to greatest extent sound reflection.
The utility model content
The purpose of this utility model is for defects of the prior art, and a kind of ventilation wedge of the anechoic chamber of can sound-absorbing, can ventilate again is provided.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: a kind of ventilation wedge of anechoic chamber, be provided with ventilation opening, and it is characterized in that its inside is provided with cage of reinforcement and is filled with damping material, and outer wrap there is sound-absorbing cloth.
In addition, the utility model also provides following attached technical scheme:
Described ventilation opening has two holes that are parallel to each other.
Described damping material is the environmental protection glass wool.
Than prior art, advantage of the present utility model is: the ventilation wedge of anechoic chamber of the present utility model, it both had been provided with ventilation opening, section is provided with again cage of reinforcement and is filled with damping material within it, outer wrap has sound-absorbing cloth, thereby can sound-absorbing and reduced to greatest extent reflection to sound, can ventilate again.
Description of drawings
Fig. 1 is the schematic perspective view corresponding to the ventilation wedge of a kind of anechoic chamber of the utility model preferred embodiment.
Fig. 2 is the plan view of Fig. 1.
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.
Referring to figs. 1 through Fig. 2, a kind of ventilation wedge 1 of anechoic chamber, as the ingredient of the compound ventilation air-changing device of anechoic chamber, it is provided with ventilation opening 5.Described ventilation opening 5 has two holes that are parallel to each other 4, all is filled with damping material around the described hole 4, and is like this, not only attractive in appearance but also reduced to greatest extent the reflection of sound.
The inside of above-mentioned ventilation wedge 1 is provided with the cage of reinforcement (not shown) and is filled with the damping material (not shown), and described damping material is the environmental protection glass wool; And outer wrap has sound-absorbing cloth, and the material of this sound-absorbing cloth is identical with other sound-absorbing wedge (not shown) with color, thereby so that whole anechoic chamber is attractive in appearance, generous.So than prior art, the ventilation wedge of anechoic chamber of the present utility model can sound-absorbing, has reduced to greatest extent the reflection of sound, ventilation opening 5 is set again, thereby plays the effect of ventilation.
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.
