Active piezoelectric beeper and piezoelectric beeper difference


"Active" refers to the buzzer itself contains the driver, it can be directly to a certain voltage can ring; "passive" is the need to rely on external drive can be ring. Note that here the "source"


HCFA - SJG does not mean power. But refers to the source of shock. In other words, the active buzzer beeper with a source of internal shock, so long as a power will be called. The passive internal oscillator without source, so if the DC signal can not make it tweet. Must use 2K ~ 5K square wave to drive it. Active buzzer is often more expensive than passive, it is because there are multiple oscillating circuits. The advantages of passive buzzer are: 1. Cheap, 2. Sound frequency control, you can make "more than the hair Sulasi" effect. 3. In some special cases, the advantage of multiplexing a control port active buzzer with an LED is that program control is convenient.
