Sound Activated Switch Using LM386 Amplifier IC Circuit Diagram
This circuit is operating on 9-12V DC. The working of this circuit is quite simple, the main component is an audio amplifier LM386 IC. Following are the steps that you should follow to make this circuit work, Sound is received by an Electret mic which converts these sound signals into electrical signals.
The straightforward sound operated switch circuit demonstrated here will probably work at a distance of up to around 2 or 3 metres from a voice of average volume (slightly-less in case the xtal microphone insert is substituted with a medium or high impedance powerful sort). These two stages depend on Q1 and Q2 and work with a simple This project uses an LM386 audio amplifier IC with a few other components to build a simple and accurate sound-activated alarm circuit. The circuit will activate a buzzer for a few seconds when the microphone receives a sound. The sensitivity of the circuit is good and it can detect sounds of the whistle, clap or finger snap from many meters away.
3 Sound Activated Switch Circuits Explained Circuit Diagram
1.Just sound of clapping[the sound of striking your palms together]. 2.Use coil pins of relay,a transistor and a diode. [I also, designed a very practical sound switch with a relay that work very good.]. Have a nice day, The Circuit. An electret microphone is a type of condenser (capacitor) based microphone that converts sound energy to electrical energy. It is a low cost microphone that can be found in every cellphone, laptop, camera, and so on. The main component of the circuit is the electret microphone and it is used as the sound sensor.
