Mic On Off Switch Circuit

When the push button s1 is pressed the transistors q2 and q3 wired as latching pair gets activated and drives the led to glow.

Mic on off switch circuit.

The main component of the circuit is the electric condenser mic which has been used as a sound sensor. If you want to keep the light function you may need a different switch dpdt. That will short out the audio signal. Condenser mic basically converts sound energy into electrical energy that in turns used to trigger 555 timer ic through a transistor.

The circuit shows a typical three wire microphone connection. To mute the microphone the switch should simply connect between pin 2 and pin 3 of the xlr connector. It works as a switch which makes devices on and off by making a clap sound. The led remains in this condition.

The circuit i posted was intended for a line output or a dynamic mic only and should not be used if there is any phantom power on the input. A condenser mic m1 is used to sense your puff. Pop free microphone on off switch circuit this electronic hobby circuit uses a simple technique to eliminate the usual pop sound when an electret type microphone is switched on or off. This is a simple circuit in which the glowing led can be switched off just by a puff.

Although its name is clap switch but it can be turned on by any sound of about same pitch of clap sound. When the switch is closed the mic will be shorted out and therefore muted.
