Passive buzzer features are1. 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 it2. Sound frequency control- you can make a “more than a meter hair Suola” effect.3. In some special cases- you can re
Active buzzer features are1. An active buzzer with a concussion internal source- so long as it will be called an energized2. Program easy to control- SCM can let a high-low sound- while passive buzzer did not.
PCB Dimensions34.28 mm (L) * 13.29 mm (W) * 11.5 mm (H)
