In this kit, we learn how to make a very simple buzzer using a piezoelectric transducer and hardly any electronic components. The simple buzzer circuit described here actually works in a quite unique way. Instead of the normal working concept employed by other forms of oscillators which require resistor and capacitor networks for generating the oscillations.
When a voltage is introduced in the circuit, the transistor conducts, operating the piezo element across the buzzer coil, however, this also leads to the grounding of the base of the transistor through the center tap of the piezo element, this instantly switches off the transistor and in turn the piezo also switches off, releasing the base of the transistor.
