Piezoelectric buzzers
Piezoelectric buzzers are a great choice when you’re looking for devices that offer lower power consumption, lack of magnetic field, and no added EMI/EMC concerns. They are often considered alarms or warning tones, and are typically found in timers, computer devices, pest deterrents, telephones, toys, and games. We carry washable, non-washable, and reflow buzzer types in several sizes, frequencies, and sound outputs.

These buzzers require an external drive circuit to operate. These buzzers are generally cheaper and more versatile, but there’s a lot more assembly required.
