Piezo buzzers use piezoelectric materials to generate sound and are more efficient and compact. Electromagnetic buzzers use a coil and magnet, offering richer tones but larger size and higher power consumption.
Active buzzers have an internal oscillator and only need DC voltage to operate—ideal for simple alerts. Passive buzzers require an external signal and offer frequency control, suitable for complex tones and melodies.
