The utility model discloses the sound isolation box who provides, test effectiveness that can the mock standard audio amplifier. Through this sound isolation box, can carry out test to the product that awaits measuring many times to in time improve the design of product according to the test result, and detect behind the improved design product property can, the great improvement that brings product development's effect.
Description
Technical field
The application relates to a kind of noise insulation equipment, particularly relates to a kind of sound proof box.
Background technology
Electro-acoustic product requires to realize in process of production the test of the background noise performance parameter of product,
Such research and development of products initial stage often to carry out substantial amounts of test to the background noise of product.Some special products
The background noise of product must pass through certification.But very limited for the standard noise elimination laboratory quantity of certification,
Thus, no matter from time or space from the point of view of, regular third-party test is all difficulty with.And product grinds
At the initial stage of sending out, regular carries out properties of product test and assessment, for the R&D direction of product and technical
Improve particularly important, if cannot be regular carry out the substandard test of this execution, it will drop greatly
Low efficiency of research and development.
But owing to the production environment noise of product to be measured is higher, and the mechanical vibration of off-gauge automatic test machine
Noise is relatively strong, realizes the test of electro-acoustic product background noise parameter the most temporarily without method.
Utility model content
This utility model provides a kind of sound proof box, calls in solution less for the distribution of the full anechoic chamber of certification, leads
Send a telegraph the problem that sound product test background noise is inconvenient.
A kind of sound proof box, wherein, described sound proof box includes casing, and described casing is overall in cylinder, described
Casing includes shell and is arranged at the described casing center inner chamber along casing axial distribution；Described inner chamber is to institute
State cabinet shell be sequentially provided with ring have mercy on the first interlayer of described inner chamber, the second interlayer, the 3rd interlayer and vacuum every
Layer.
Described sound proof box, wherein, is filled with glass fibre acoustical cotton in described first interlayer.
Described sound proof box, wherein, is filled with polyester fiber acoustical cotton in described second interlayer.
Described sound proof box, wherein, is filled with crest acoustical cotton in described 3rd interlayer.
Described sound proof box, wherein, is provided with vibration abatement, described vibration abatement one end in described vacuum interlayer
Being arranged at the inner wall surface of described shell, the other end of described vibration abatement is solid with the outer wall of described 3rd interlayer
Fixed connection.
Described sound proof box, wherein, described box bottom is additionally provided with leg.
Described sound proof box, wherein, described casing one end vertically is provided with the unlatching for putting into test piece
Door.
Sound proof box given by this utility model, it is possible to the test effect of mock standard audio amplifier.By this sound insulation
Case, can carry out test repeatedly to product to be measured, and improve the design side of product according to test result in time
Properties of product after case, and detection improvement design, the bigger raising that the effect of research and development of products is brought.
Accompanying drawing explanation
Fig. 1 is in the present embodiment, the front view of sound proof box；
Fig. 2 is the A-A item sectional view of Fig. 1.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
Sound proof box given by the present embodiment, as Figure 1-Figure 2, including sound proof box casing 1.And it is positioned at case
Leg 2 bottom body 1.Casing 1 entirety is cylinder, and it includes shell 15, is positioned at casing 1 one end
Unlatching door 16, and it is arranged at the inner chamber 10 of casing 1 center, inner chamber 10 axially divides along casing 1 is cylindrical
The cavity of the cylindric hollow of cloth.It is sequentially provided with first interlayer the 11, second interlayer by inner chamber 10 to shell 15
12, the 3rd interlayer 13 and vacuum interlayer 14.First interlayer the 11, second interlayer the 12, the 3rd interlayer 13 grades is true
Empty interlayer 14 ring inner chamber 10 of having mercy on successively is distributed.
Further, as in figure 2 it is shown, be filled with glass fibre acoustical cotton, the second interlayer in the first interlayer 11
Fill by polyester fiber acoustical cotton in 12, in the 3rd interlayer 13, be filled with the crest acoustical cotton that surface is wedge shaped.
Designed by the interlayer of three different fillings, the sound wave of different-waveband can be absorbed, with the vacuum in outside every
Layer 14 together constitutes a wide band sound absorber.Enhance soundproof effect so that the sound insulation of inner chamber 10
Excellent.
Additionally, be additionally provided with vibration abatement 17 in vacuum interlayer 14, this vibration abatement one end is fixedly installed and shell
The surface of inwall, the outer wall of the other end and the 3rd interlayer 13 is fixing to be connected.Vibration abatement 17 is along vacuum interlayer
The cross-sectional periphery direction of 14 is the setting of decussation.In the present embodiment, 17 antirattle spring of vibration abatement,
As in figure 2 it is shown, four antirattle spring being positioned at same cross section are one group, have many along casing 1 axial distribution
Group antirattle spring.Greatly weaken from the impact on inner chamber 10 of the shock wave in ground or air.
During use, by opening door 16, workpiece for measurement is sent in inner chamber 10, then unlatching door 16 is closed i.e.
Can, open door 16 and be provided with sealing device, after opening door 16 closedown, shell 15 i.e. enters complete sealed shape
State.
Sound proof box given by this utility model, it is possible to the test effect of mock standard audio amplifier.By this sound insulation
Case, can carry out test repeatedly to product to be measured, and improve the design side of product according to test result in time
Properties of product after case, and detection improvement design, the bigger raising that the effect of research and development of products is brought.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to recognize
Determine the application be embodied as be confined to these explanations.Ordinary skill for the application art
For personnel, on the premise of conceiving without departing from the present application, it is also possible to make some simple deductions or replace
Change.
