Abstract
The invention discloses a drawing plate of an anechoic chamber, which can be installed on a bottom plate in the anechoic chamber. A plurality of openings are arranged on the surface of the drawing plate to reduce reflection of the drawing plate to sound and increase the sound absorption rate.
Description
Technical field
The present invention relates to a kind of anechoic chamber, relate in particular to a kind of pull plate 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 studio, Shop floor control chamber or noise measurement chamber.Therefore, the anechoic chamber to the requirement of airtight performance and acoustic characteristic than higher.
The pull plate of its inner support testee of existing anechoic chamber is generally fixed, like this for testee to pack into or take out be very inconvenience, and the material of pull plate is common wooden, is unfavorable for sound insulation like this.In addition, the surface of said pull plate is designed for tabula rasa, so can be unfavorable for sound insulation to sound generating than the strong reflection effect.So, be necessary to provide a kind of pull plate of improved anechoic chamber.
Summary of the invention
Fundamental purpose of the present invention is to propose a kind of pull plate of improved anechoic chamber, and it can reduce the reflection to sound, increases acoustic absorptivity.
For realizing the foregoing invention purpose; The present invention has adopted following technical scheme: a kind of pull plate of anechoic chamber; Said pull plate can be installed on the base plate in the said anechoic chamber, it is characterized in that: the surface of said pull plate is provided with plural a plurality of perforate to reduce the reflection of said pull plate to sound.
In addition, the present invention also comprises following attached technical scheme:
Plural a plurality of perforates of said pull plate are the small sircle hole that is arrayed.
Said pull plate is processed by acoustical material.
The shell of said anechoic chamber adopts steel construction.
Offer through wires hole on the shell of said anechoic chamber.
Compared with prior art, the invention has the advantages that:, increase acoustic absorptivity through plural a plurality of perforate is set on the pull plate of anechoic chamber to reduce reflection to sound.
Description of drawings
Fig. 1 is the sectional perspective view corresponding to the anechoic chamber of preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment technical scheme of the present invention is elaborated.With reference to Fig. 1, a kind of anechoic chamber, its shell adopts steel construction to process, and makes that the soundproof effect of anechoic chamber is better, and is more firm, more attractive in appearance.This anechoic chamber is roughly cuboidal configuration, comprises Qianmen 1, base plate 3 and can be installed in the pull plate 5 on the base plate 3 in the said anechoic chamber.
Said Qianmen 1 is provided with rotating handles 7 to open or close Qianmen 1.Also offer sealing through wires hole 9 on the sidewall of said anechoic chamber, it can make the test probe of connection testing tool and the data line of instrument host (figure does not show) pass through, and can guarantee the sealing in aperture simultaneously.
Said pull plate 5 is used to place testee (figure does not show), and it is processed by acoustical material, such as the spun glass acoustical cotton.The surface 11 of this pull plate 5 is provided with plural a plurality of perforate 13 to reduce the reflection of 5 pairs of sound of pull plate, increases acoustic absorptivity.The a plurality of perforates 13 of said plural number are for being the small sircle hole of arrayed.
In addition, said pull plate 5 is equipped with roller 15, and roller 15 comprises four, is installed in the both sides of the bottom surface of pull plate 5 respectively.And the base plate 3 of anechoic chamber is provided with two guide rails 17, and above-mentioned rollers 15 can move on corresponding guide rail 17, thereby drives pull plate 5 moving with respect to base plate 3.In addition, also being provided with handle 19 on the front surface of pull plate 5 moves along guide rail 17 with pulling or promotion pull plate 5.Like this, when testee (figure do not show) is positioned over 5 last times of said pull plate, thereby through pull plate 5 being carried out move easily the test position that reaches best, for test operation provides convenient and comfortable.
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)
