A 5V buzzer in the familiar round black case about 12 mm across with two straight pins, sold as the active type - the oscillator is inside, so a steady 5V is all it needs to sound. That makes it the simple choice for alarms, timer alerts, key clicks and sensor-tripped feedback. The distinction worth knowing: an active buzzer gives one fixed tone from plain DC, while a passive transducer needs a square wave from a pin (Arduino's tone()) and can play different pitches.
