3V-27V Big Piezo BuzzerPiezo Buzzer is an electronic device generally used to produce sound. A piezo buzzer is different from a magnetic buzzer in that it is driven by a voltage rather than a current. A piezo buzzer is modelled as a capacitor while a magnetic buzzer is modelled as a coil in series with a resistor. This Piezo buzzer can work on a wide voltage range.
