Buzzer Circuit Picture. If a current drives through the coil an magnetic field is produced. The simple piezo buzzer circuit described here actually works in a quite unique way.
Figure 1 the simple electronic buzzer circuit by two transistor. One bc548 transistor or other similar npn transistor. Hi friends today i will show how to make buzzer out of relay.

Relay is nothing but a switch which is controlled by voltage which we provide. The coil of wire is connected to the power supply of the magnetic buzzer. Figure 1 the simple electronic buzzer circuit by two transistor. The piezo element must be a three terminal one like in the picture.
