Differences between active and passive buzzer

The main difference between an active and passive buzzer is that an active buzzer generates sound on its own. To do this, the user simply has to turn it on or off, in other words, by energizing or de-energizing the contacts. A passive buzzer, on the other hand, requires a signal source that will set the parameters of the sound signal. An Arduino board can act as such a source. An active buzzer will emit a louder sound signal than its competitor. The frequency of the emitted sound of the active buzzer is 2.5 kHz +/- 300Hz. The supply voltage for the squeaker varies from 3.5V to 5V.

This buzzer is not suitable for installation on flight controllers where mainly active beepers are used.
