I can explain the function of different buzzers and use them as output components in a control system.
Muuji qoraalka
Buzzers are output devices which convert an electrical signal into a sound.
There are two types of buzzers, electromechanical and piezoelectric.
An electromagnetic coil is used in an electromechanical buzzer to move a piece of metal which makes the sound.
In a piezoelectric buzzer, the smart material flexes and makes the sound.
Changing the frequency of the movement in the buzzer changes the pitch we hear.
