High Quality Active Buzzer Module for Arduino New DIY Kit Active buzzer low level modules
 
Now there are a lot of people to the concept of passive and active buzzer buzzer is not very clear, do a simple introduction here, hope to help everyone to use in the future
 
Note that in this case, the "source" is not the power supplyIt 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 itMust 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
