In telecommunications, a voice operated switch, also known as VOX or voice-operated exchange, is a switch that operates when sound over a certain threshold is detected. It is usually used to turn on a transmitter or recorder when someone speaks and turn it off when they stop speaking. It is used instead of a push-to-talk button on transmitters or to save storage space on recording devices. On cell phones, it is used to save battery life. Intercom systems that use a speaker in a room as both a speaker and a microphone will often use VOX on the main console to switch the audio direction during a conversation. The circuit usually includes a delay between the sound stopping and switching direction, to avoid the circuit turning off during short pauses in speech.

The application belongs to the technical field of switches and particularly relates to a sound control switch system, which comprises a sound control assembly and a master control module. The sound control assembly comprises a sound collecting piece and a detachable module. The detachable module comprises a driving piece, a lever transmission piece and a fixing piece. The lever transmission piece is vertically arranged outside a switch panel and has protrusions at both ends. The middle section is fixedly connected with the driving piece. The driving piece is fixed on a base by the fixing piece. The master control module is connected with the sound collecting piece and the driving piece. The master control module is used for controlling the driving piece to rotate towards the direction of closing the switch panel in response to the sound collected by the sound collecting piece, so as to drive the lever transmission piece to rotate and close the switch panel. The sound control switch system controls the state of the switch panel through the cooperation of various devices. The detachable module has a simple structure. The detachable module and other sound control related devices can be installed on the basis of the installed mechanical switch to realize the sound control function, which is convenient for assembly, disassembly and maintenance and is conducive to reducing the use cost.
