Drive a piezoelectric buzzer with a simple boost converter ... Drive a piezoelectric buzzer with a simple boost converter A piezoelectric buzzer is a loudspeaker that uses the piezoelectric effect to generate sound. Its lightweight, simple construction and low price make it usable in many applications, such as home appliances, shared bikes and alarm devices. Self Drive Piezo Buzzer Hackster.io The piezo effect works both ways: if you apply a voltage the piezo stretches, but also if it stretches it creates a voltage. This principle is used to create a feedback signal which drives the oscillator. The advantage of the self drive is that it will automagically work at its resonance frequency, where it produces the loudest sound.
