The acoustic module is regular triangular prism.
The adjustable listening room of acoustic efficiency also includes the rotating mechanism being connected on the mounting bracket, the whirler
Structure can drive the acoustic module to rotate.
The rotating mechanism includes the drive sprocket and driven sprocket being rotatably connected with the mounting bracket and the active
The matched chain of sprocket wheel, driven sprocket, the rotating sprocket rotated by chain-driving and the connection rotating sprocket and acoustics
The rotary shaft of module.
The adjustable listening room of acoustic efficiency also includes the drive device being connected with the rotating mechanism, the driving dress
Put the driving drive sprocket rotation.
The drive device is at least one of manual rocking handle or reducing motor.
Compared to prior art, the advantage of the invention is that：The listening room of the present invention is allowed to have by rotating acoustic module
There is facing outwardly for different acoustic properties, so that the acoustic efficiency of anechoic chamber can carry out artificial regulation, change original
The single present situation of anechoic chamber's acoustic efficiency, meets the testing requirement of multiple product, improves the utilization rate of listening room, saved into
This.
