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.
Buzzer:an audio signalling device.Uses of buzzers include alarm
devices,timers, and confirmation of user input such as a mouse
What is the advantage and disadvantage of a buzzer?
Advantages:Electrically operated device that is good for drawing
attention to a condition that requires attention.
Disadvantages:1.Annoying sound to those that don't know its
2.Requires training to know what the buzzer means, and how to
repair the condition without just shutting off the buzzer.
3.Could trigger a fire in an explosive atmosphere.
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.
