Buzzer Classification Guide
By Driving Method
Active Buzzer (includes driving circuit, self-excited) and Passive Buzzer (requires external drive, other-excited)
By Construction Type
Electromagnetic Buzzer and Piezoelectric Buzzer
By Package Style
DIP Buzzer (Pin Type) and SMD Buzzer (Surface Mount)
By Current Type
DC Buzzer and AC Buzzer
Technology Comparison
Piezoelectric buzzers use materials that generate electrical charges when deformed, offering simple construction and durability with consistent tone suitable for alarms.
Electromagnetic buzzers utilize magnetic fields generated by conductive conductors interacting with permanent magnets to drive diaphragms, providing superior timbre for voice and music applications.
