Noise echo elimination device based on video conference

Abstract

The invention discloses a noise echo elimination device based on a video conference. The noise echo elimination device comprises multiple microphone modules which are connected with a microphone switch module through a CAN bus. Each microphone module is connected with an audio vibration module and a voice detection module. The voice detection modules detect voice information of the microphone modules and transmit the voice information to a SIP control center. The audio vibration modules detect audio vibration information of the microphone modules and transmit the audio vibration information to the SIP control center. The SIP control center receives the voice information of the voice detection module to be compared with a database and detects whether the voice information content includes preset voice X and transmits a microphone turn-off instruction to the microphone switch module if the voice information content includes the preset voice X. The microphone switch module receives the instruction and turns off the corresponding microphone module. The vibration information transmitted by the audio vibration modules is continuously received and a microphone turn-on instruction is transmitted to the microphone switch module. The microphone switch module receives the turn-on instruction and turns on the corresponding microphone module.
