Features:
Passive buzzer features are:
1. Passive internal shocks without source- so if you can not make it with a DC signal tweet. Must be a square wave 2K ~ 5K to drive it 2. Sound frequency control- you can make a “more than a meter hair Suola” effect. 3. In some special cases- you can reuse a control and LED mouth
Active buzzer features are:
1. An active buzzer with a concussion internal source- so long as it will be called an energized 2. Program easy to control- SCM can let a high-low sound- while passive buzzer did not.
