Product description:-
- passive buzzer is characterized:1. Passive internal without shock source, so if the DC signal cannot be its tweet. Must use 2K ~ 5K of square wave to drive it
- 2.Sound controllable frequency may be made "duo flammi by Sola West effect.
- 3.in some particular case, the can and LED reuse one control port
