Buzzers can be categorized into active and passive ones the schematic diagram of the module is as follows. The difference between an active buzzer and a passive buzzer is. It is very small and compact 2 pin structure hence can be easily used on breadboard perf board and even on pcbs which makes this a widely used component in most electronic applications.
As we have discussed in the above paragraph signal voltages are required to turn on or off the buzzer in an active and passive configuration.
These buzzers are usually driven at a relatively higher voltage but low current consumes a little power but. An active buzzer has a built in oscillating source so it will make sounds when electrified. Updated june 8 2017 by arnab. Piezo buzzers are one of the most common buzzers available around they got their name from the piezoelectric material used as the active element.
