The characteristics of the passive buzzer are:
1. There is no vibration source inside the passive, so it can not beep with DC signal. It must be driven by 2k~5k square wave
2. The sound frequency can be controlled, which can make the effect of "dolamifasolasi".
3 in some special cases, a control port can be multiplexed with an LED
The features of the active buzzer are:
1. The active buzzer has an internal vibration source, so it will sound as soon as it is powered on
The program control is convenient. The single chip microcomputer can make it sound at a high or low level, but the passive buzzer can't.
Each set weighs about 6g
