Nowadays, many people don't know the concept of active buzzer and passive buzzer. Here is a brief introduction, which I hope is helpful for you to use later. Notice that the source here is not the power. It means the source of shock. The characteristics of the passive buzzer are : 1, there is no shock source inside the passive, so if it can't be tween by DC signal. A square wave of 2K~5K must be used to drive it 2 voice frequency controllable, can make "to send Tracy cable" effect. 3, in some special cases, a control port can be multiplexed with LED. The characteristics of the active buzzer are: 1, the active buzzer has a shock source inside, so it will be called as long as it is electrified. 2, program control is convenient. A high and low level of MCU can make it sound, but passive buzzer can not do it.
