A buzzer can distinguish the sound generation principle as magnetic, piezo, and mechanical, all of which are equipped with an internal driving circuit (Active) and can output a fixed single frequency sound using direct current voltage (Vdc). The buzzer is plug and play (PNP) design, which allows customers to simplify their circuit design. It provides a variety of terminals such as pin, wire, SMT, and solder-pad available for customers' different assembly requirements.
A magnetic buzzer operated by a magnet and coil and built-in oscillation created a condition for the output of a loud sound with low voltage. Also, the stable performance makes sure your every dollar is worth it.
A piezo buzzer has a simple structure, operated by a piezo element and built-in oscillation. It provided a wide frequency range from 1KHz to 4.5KHz, suitable for the design that requested a more flexible tone.
