Active Buzzer Module Aktív hangjelző alacsony szintű modulok
Active Buzzer Module Active buzzer low level modules
Note that in this case, the "source" is not the power supply.It is the volatile source.
 
 
The characteristics of the passive buzzer is:
1 passive internal without shock source, so if use dc signal can't make it.Must use 2 k ~ 5 k square wave to drive it
For more than 2 sound frequency control, can make "m hair sola west" effect.
3 in some particular case, can reuse and LED a control
 
 
The characteristics of the active buzzer is:
1 Active buzzer inside with shock source, so as long as the electricity will call
2 Program control convenient, single chip microcomputer a high and low level can make the sound, and the passive buzzer is can't do.
Each weight is about 6 g
