Abstract
The invention discloses a sound absorption wedge unit for an anechoic chamber. The sound absorption wedge unit comprises a base part and a tip part extending downward from the base part. The sound absorption wedge unit is characterized in that a groove is arranged on the sound absorption wedge unit; and the groove extends to an inside of the tip part from a top face of the base part. With the adoption of a structure that a bottom part of the sound absorption wedge unit is hollowed to form the groove, the entire mass of the sound absorption wedge unit can be reduced. Therefore, the sound absorption wedge unit is good for mounting and bearing a floor of the anechoic chamber.
Description
Technical field
The present invention relates to a kind of sound-absorbing wedge unit 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, to the requirement of anechoic chamber's sound absorption qualities than higher, so, also higher relatively to the requirement of sound-absorbing wedge unit, anechoic chamber.
The sound-absorbing wedge unit of existing anechoic chamber is made up of tip and base portion; Its internal construction is that the reinforcing bar bending of 4mm or 6mm is welded into the cage of reinforcement that profile is a wedgelike by diameter;, plastic-blasting fills centrifugally glass-wool or other damping materials after handling; Tamp back outer bread glass fabric one deck at acoustical cotton, the contaminated environment in case acoustical cotton leaks outside, wrap up with sound-absorbing cloth the outside of glass fabric again.This solid structure makes that the material of sound-absorbing wedge unit is many, and quality is heavy, is unfavorable for installing and the floor load-bearing of anechoic chamber.So, be necessary to provide this improved.
Summary of the invention
The objective of the invention is to above-mentioned defective of the prior art, a kind of sound-absorbing wedge unit of improved anechoic chamber is provided, it helps installing and the floor load-bearing of anechoic chamber.
For realizing the foregoing invention purpose; The present invention has adopted following technical scheme: a kind of sound-absorbing wedge unit of anechoic chamber; Comprise base portion and from said base portion to the tip that extends below; It is characterized in that: said sound-absorbing wedge unit offers groove, and said groove extends downward the inside of said tip from the end face of said base portion.
In addition, the present invention also provides following attached technical scheme:
Said base portion and said tip are formed in one.
Said sound-absorbing wedge whole unit is a bullet.
Said groove is a bullet.
Said sound-absorbing wedge unit is processed by damping material.
Description of drawings
Fig. 1 is the schematic perspective view corresponding to the sound-absorbing wedge unit of a kind of anechoic chamber of preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical scheme of the present invention is done further nonrestrictive detailed description.
With reference to Fig. 1; A kind of sound-absorbing wedge unit of anechoic chamber, comprise base portion 1 and from said base portion 1 to the tip that extends below 2, its internal construction is that the reinforcing bar bending of 4mm or 6mm is welded into the cage of reinforcement that profile is a wedgelike by diameter;, plastic-blasting fills centrifugally glass-wool or other damping materials after handling; Tamp back outer bread glass fabric one deck at acoustical cotton, the contaminated environment in case acoustical cotton leaks outside, wrap up with sound-absorbing cloth the outside of glass fabric again.Said sound-absorbing wedge unit offers groove 3, and said groove 3 extends downward the inside of said tip 2 from the end face 4 of said base portion 1.
In addition, said base portion 1 is formed in one with said tip 2.
Said sound-absorbing wedge whole unit is a bullet.
Said groove 3 is a bullet.
Said sound-absorbing wedge unit is processed by damping material.
Than prior art, the sound-absorbing wedge unit of anechoic chamber of the present invention hollows out the centre position of its bottom and forms groove 3, and like this, the material of usefulness is fewer, and lighter weight helps installing and the floor load-bearing of anechoic chamber.
It is pointed out that above-mentioned preferred embodiment is merely explanation technical conceive of the present invention and characteristics, its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (5)
1. the sound-absorbing wedge unit of an anechoic chamber, comprise base portion and from said base portion to the tip that extends below, it is characterized in that: said sound-absorbing wedge unit offers groove, and said groove extends downward the inside of said tip from the end face of said base portion.
2. according to the sound-absorbing wedge unit of the said anechoic chamber of claim 1, it is characterized in that: said base portion and said tip are formed in one.
3. according to the sound-absorbing wedge unit of the said anechoic chamber of claim 1, it is characterized in that the whole bullet that is.
4. according to the sound-absorbing wedge unit of the said anechoic chamber of claim 3, it is characterized in that: said groove is a bullet.
5. according to the sound-absorbing wedge unit of each said anechoic chamber in the claim 1 to 4, it is characterized in that it and process by damping material.
