But rather refers to the shock source. Passive buzzer is characterized by: A passive internal sources without shocks, so if the DC signal can not make it with a tweet. Must 2K ~ 5K square wave to drive it 2 sound frequency controllable, you can make a "more than a meter hair Suola Xi" effect. 3 In some special cases, you can reuse a control and LED mouth Active buzzer is characterized by: An active internal buzzer with shock source, so long as a power will be called 2 program easy to control, SCM can allow a high and low sounds, while passive buzzer can not.
