Pins or wires type. Frequency is generally low. The mechanical
buzzer is a special electromagnetic buzzer,composed of oscillator,
the electromagnetic coil, the magnet and shell.Vibration piece is
installed on the shell.
How to distinguish active and passive buzzer?
An active buzzer will generate a tone using an internal oscillator,
so all that is needed is a DC voltage.
A passive buzzer requires an AC signal to make a sound.
To identify them, if you apply a DC voltage to them and it buzzes,
it's an active.
Buzzer:an audio signalling device.Uses of buzzers include alarm
devices,timers, and confirmation of user input such as a mouse
