Description
Technical field
The utility model relates to acoustical testing technical field more particularly to a kind of Acoustic test boxes of light sound insulation.
Background technique
Loudspeaking electronic product generally required after the manufacturing carry out associated acoustic test, thus to its acoustical behavior into
Row accurate evaluation.The existing device for acoustical testing, in order to guarantee preferable sound insulation enclosed environment, often through construction one
Dedicated sound insulation house, so that test carries out in sound insulation house.However, the volume of sound insulation house is big, is difficult to the disadvantages of shifting makes it
Seem very inconvenient under more occasion use demands；In addition, the sound that minor motion of the tester in sound insulation house is issued
It may also influence whether the accuracy of test process.
Utility model content
The purpose of this utility model is to provide a kind of Acoustic test boxes of light sound insulation, in test, debugging electronics
Product provides the test environment of light, higher sound transmission loss when testing by related audio, to ensure the accuracy tested and debugged.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of Acoustic test box of light sound insulation, the Acoustic test box are made of cabinet and chamber door, the cabinet and case
Door is made of sound insulation composite material；The sound insulation composite material successively includes color steel plate, soundproof plate, long fibre suction from outside to inside
Sound-absorbing layer, micropunch aluminium sheet；The chamber door is made of removable doorframe, fixed door, dodge gate, hinge；The removable doorframe passes through can
It tears open and is bolted the cabinet, and be equipped with mounting groove, the fixed door and dodge gate in removable doorframe and be rotatablely connected by hinge,
And it is embedded in the mounting groove.
In a certain embodiment: the edge of the dodge gate, which is integrally formed ground and is equipped with, extends retaining wall, the extension retaining wall face
Side to outside case is equipped with damping sound insulation felt.
In a certain embodiment: the bottom surface of the cabinet is equipped with 4 universal rolling wheels.
In a certain embodiment: the soundproof plate, long fibre sound absorbing layer, micropunch aluminium sheet thickness be respectively 5mm,
10mm、3mm。
In a certain embodiment: the long fibre sound absorbing layer is PE or monofilament；The soundproof plate is PE plate or high-density plate.
The working principle and its advantage of the utility model are: trial product to be measured and test equipment are passed through activity by tester
Door is sent into Acoustic test box, and corresponding testing process is carried out, and tester can be realized outside test box by signal corresponding
Test operation, so that test accuracy will not be influenced because of the movement of tester.The dodge gate passes through hinge and fixed door
It realizes and relatively rotates, to open the dodge gate；At closing time, dodge gate and removable doorframe are connected by conventional lock, to realize
The opening and closing of dodge gate.It, can be by operating removable bolt for removable doorframe from cabinet when the volume of product to be measured is larger
After upper dismounting, then product to be measured is put into, due to bolted mode securely and convenient for repeating to dismount, so that the acoustics is surveyed
Examination case can be adapted to the product to be measured within the scope of certain volume, have a wide range of application.Since the volume of Acoustic test box is little,
Test box can shift between multiple occasions and movement, and different research and development of products departments is allowed to share same acoustical testing
Case, good portability.
Detailed description of the invention
Fig. 1 shows the front view of the utility model embodiment Acoustic test box；
Fig. 2 shows the structural schematic diagrams of the utility model embodiment sound insulation composite material；
Fig. 3 shows the stereoscopic schematic diagram of the utility model embodiment dodge gate.
Specific embodiment
Please refer to Fig. 1-3, the utility model provides a kind of Acoustic test box of light sound insulation, the Acoustic test box by
Cabinet 1 and chamber door 2 form, and the cabinet and chamber door are made of sound insulation composite material 9.The sound insulation composite material is from outside to inside
It successively include color steel plate 91, soundproof plate 92, long fibre sound absorbing layer 93, micropunch aluminium sheet 94.The soundproof plate, long fibre sound-absorbing
Layer, micropunch aluminium sheet all have good sound insulation value, and the color steel plate provides the support of Acoustic test box mechanical property, and
It can be in the corresponding appearance coating of its trypsin method, to provide the Acoustic test box of different appearances.In specific structure, the soundproof plate
92, long fibre sound absorbing layer 93, micropunch aluminium sheet 94 thickness be respectively 5mm, 10mm, 3mm, it is described thus in the present embodiment
The sound transmission loss of sound insulation composite material 9 is 35db.In one preferred embodiment, the long fibre sound absorbing layer 93 is PE or monofilament；It is described
Soundproof plate 92 is PE plate or high-density plate.
In addition, to improve the test convenience of the Acoustic test box, the chamber door 2 by removable doorframe 21, fixed door 22,
Dodge gate 23, hinge 24 form.The removable doorframe 21 connects the cabinet 1 by removable bolt 25, and sets in removable doorframe
There is mounting groove, the fixed door 22 is rotatablely connected with dodge gate 23 by hinge 24, and is embedded in the mounting groove.
By configuring above, trial product to be measured and test equipment are sent into Acoustic test box by dodge gate 23 by tester
It is interior, corresponding testing process is carried out, tester can pass through signal outside test box and realize corresponding test operation, thus will not
Because the movement of tester influences test accuracy.The dodge gate realizes relative rotation by hinge 24 and fixed door 22,
To open the dodge gate 23；At closing time, dodge gate 23 and removable doorframe 21 are connected by conventional lock, to realize dodge gate
It opens and closes.When the volume of product to be measured is larger, removable doorframe can be removed from cabinet by operating removable bolt 25
Afterwards, then by product to be measured it is put into, due to bolted mode securely and convenient for repeating to dismount, enables the Acoustic test box
The product to be measured being enough adapted within the scope of certain volume, has a wide range of application.
In the present embodiment, the edge of the dodge gate 23, which is integrally formed ground and is equipped with, extends retaining wall 231, the extension retaining wall face
Side to outside case is equipped with damping sound insulation felt.So that carrying out preferable ground resistance to incoming outflow of the sound in dodge gate gap
Every preferably enhancing the sound insulation value of Acoustic test box.
Since the volume of Acoustic test box is little, test box can shift between multiple occasions and mobile, portability
It is good, allow different research and development of products departments to share same Acoustic test box.Further, the bottom surface of the cabinet is equipped with
4 universal rolling wheels, when so as to transfer between multiple occasions, carrying and transfer to Acoustic test box provide more convenient and fast
Travelling performance.
The above is only the preferred embodiment of the present invention, is not intended to limit its scope of the patents, all to utilize this
Equivalent structure transformation made by utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain is also included in the patent protection scope of the utility model.
