Ask the reverberation time be 0.5 second or other, cause the size walls structure inside listening room all different.So, it is necessary to producer
All products of listening room aptitude test of more various criterions are bought, cause very big funds to bear, utilization ratio can also reduce.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art, there is provided a kind of adjustable audition of acoustic efficiency
Room, the testing requirement of multiple product can be met, improve listening room utilization rate, and it is cost-effective.
For achieving the above object, present invention employs following technical scheme：A kind of adjustable listening room of acoustic efficiency,
The adjustable listening room of acoustic efficiency includes metope, turnable the acoustic module being installed on the metope, the acoustics
Module comprises at least two kinds of different acoustic properties.
In addition, the present invention also proposes following attached technical scheme：
The acoustic module includes sound-absorbing face and reflecting surface.
The sound-absorbing face is pasted with acoustical cotton, and the reflecting surface is smooth irony plane or wooden plane.
The metope includes mounting bracket, and the acoustic module is installed on the metope by the mounting bracket.
The mounting bracket includes left sheet metal component and right sheet metal component, and the acoustic module is installed on the left sheet metal component and described
Between right sheet metal component.
The left sheet metal component is L-shaped, and the right sheet metal component and the left sheet metal component are symmetrical.
The left and right sheet metal component is pasted with sponge or rubber with the surface that the acoustic module contacts.
The acoustic module is in tabular.
The adjustable listening room of acoustic efficiency also includes the suspension arrangement being installed on metope, and the acoustic module includes
Rope, the acoustic module is by the rope suspensions on the suspension arrangement.
The suspension arrangement is iron nail or hook.
Compared to prior art, the advantage of the invention is that：1. the adjustable listening room of acoustic efficiency of the present invention can pass through
Upset changes acoustic module to change the acoustic efficiency of listening room so that the listening room can meet the test need of multiple product
Ask, it is cost-effective.2. acoustic module upset, changing, being easy to loading and unloading, aided in without other instruments.

Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
Embodiment 1：
As shown in Figures 1 to 4, corresponding to a kind of preferred embodiment of the adjustable listening room of acoustic efficiency of the present invention, including：
Metope 1, the turnover acoustic module 2 being installed on the metope 1.Metope 1 includes mounting bracket 5, and mounting bracket 5 includes symmetrically setting
The left sheet metal component 6 and right sheet metal component 7 put, the left cross sectional shape of sheet metal component 6 is L-shaped, the right cross sectional shape of sheet metal component 7 and left sheet metal component 6
Symmetrically.Acoustic module 2 is in tabular, and two maximum faces of its area are respectively sound-absorbing face 3 and reflecting surface 4, and the surface of sound-absorbing face 3 is pasted
With acoustical cotton, the sound-absorbing effect in sound-absorbing face can be adjusted using the acoustical cotton of different-thickness；Reflecting surface 4 is smooth irony
Plane or wooden plane, its absorptivity to sound is very low, and wooden plane is used in the present embodiment, can mitigate acoustic module 2
Weight.When acoustic module 2 is attached on mounting bracket 5, only acoustic module 2 need to be stuck in left sheet metal component 6 and right sheet metal component 7 it
Between, sponge or rubber can also be pasted on left and right sheet metal component 6,7, sponge is used in the present embodiment, works as acoustic module
2 loaded on mounting bracket 5 when, sponge is squeezed deformation and gives acoustic module 2 one extruding forces so that acoustic module 2 is difficult for drop-off.
Change acoustic module 2 towards when, acoustic module 2 need to only be removed from mounting bracket 5, is reloaded into mounting bracket 5 i.e. after turn-over
Can.
In use, multiple mounting brackets 5 should be installed on multiple metopes 1 of listening room on demand, typically with acoustic module 2
Metope, which can be paved with, to be advisable, and acoustic module 2 is attached on mounting bracket 5 afterwards, makes sound-absorbing face 3 towards metope or reflecting surface 4 towards wall
Face.Make the facing outwardly to obtain the different acoustic efficiency of listening room of its different acoustic properties by overturning acoustic module 2.Separately
Outside, it may be equipped with that the acoustic module 2 of different acoustic properties is standby, such as the acoustic modes with different attaching different-thickness acoustical cottons
Block 2 so that its sound-absorbing effect it is different, it is necessary to when change standby acoustic module 2 to reach more rich acoustic efficiency.
Embodiment 2：
As shown in Figure 5 and Figure 6, the present embodiment includes metope 1, is installed on the suspension arrangement 9 and acoustic module 2 of metope 1,
Suspension arrangement 9 can make hook or iron nail, and rope 10 is connected with acoustic module 2, remaining structure with phase in embodiment 1
Together.The rope 10 in acoustic module 2 need to be only hooked during use to suspension arrangement 9, suspension arrangement 9 can have it is multiple, with acoustics
Module 2 can be covered with metope and be advisable, it is necessary to when changing the acoustic efficiency of listening room, as needed by the acoustic module 2 of required turn-over
Turn-over.Equally, the acoustic module 2 that with embodiment 1, can also be equipped with different acoustic efficiencies it is standby, it is necessary to when change
Standby acoustic module 2 is gone up to reach more rich acoustic efficiency.
Acoustic module 2 is arranged on metope 1 in Fig. 1 and Fig. 5 still very big gap, is being shown for image at this
Meaning, it can arrange during actual use more compact, to reach more preferable effect, in addition, the shape of acoustic module 2 does not limit
