Description
About the Circuit:
The sound signals generated in the nearby room (even at a distance of 5 meters) are received by condenser microphone shown in the circuit diagram. The microphone converts the sound signals into electrical signals which are amplified by IC1. The output is again amplified by push pull amplifier which consists of npn and pnp transistors namely T1 and T2 respectively. This amplified output is then given to 8W Loudspeaker, which converts these electrical signals into corresponding sound signals that can be heard.
