Preferably, described main microphone is also connected by control line with central processing unit, can by control line directly with
Central processing unit is connected, and be controlled central processing unit uses selection, raising right to choose from microphone speech.
Preferably, described central processing unit uses digital signal processor (DSP) chip, improves at DAB
Effect is managed, the voice of spokesman can be made apparent, more fidelity.
Preferably, described voice band filter is provided with the anti-RF Radio frequency interferences flexible pipe for function of being uttered long and high-pitched sounds with suppression, can
The effective audio that suppresses is whistled phenomenon, it is ensured that the purity level of audio, improves the quality of audio.
Preferably, described display screen, which is used, can show current microphone ID OLED LCDs in real time, can
The ID of current microphone is shown, loudspeaker, the volume of earphone, current working condition, display language can independently be adjusted to China and Britain
Text display, chairman has priority function, can control and represents the speech of speech unit, prohibits speech etc..
Preferably, the horizontal sextant angle between described sound, two loudspeakers of video both sides is 120 degree, passes through 120 degree
Angle can prevent from producing magnetic altogether when two loudspeakers from using, it is to avoid noise occur.
The beneficial effects of the invention are as follows：
1), realize that the processing to audio system is controlled, progress is voluntarily controlled without flight crew, control effect is improved, to carry
High that different audios are carried out with Select to use, noisy, the raising audio quality in reduction meeting-place improves scene acoustical quality, operation side
Just, software implementation adjustment and control are simple.
