Explore a range of buzzers for electronic circuits, alarms, Arduino projects, control panels and signaling applications. The category includes active buzzers, passive buzzers and piezo buzzers with different operating voltages, dimensions and sound characteristics.
Choose the appropriate buzzer according to supply voltage, operating type, frequency range, sound level and mounting dimensions. Buzzers are commonly used for audible alerts, status indication, alarms and user feedback in electronic devices.
Active vs Passive Buzzer
An active buzzer contains an internal oscillator and generally produces sound when the specified DC voltage is applied. A passive buzzer requires an external signal or frequency generated by a microcontroller or another circuit, allowing greater control over the produced tone.
Piezoelectric buzzers are widely used in Arduino projects, alarms, electronic devices, control systems and notification circuits. Before selecting a model, check its operating voltage, polarity, dimensions and whether an external drive signal is required.
