Hello.

I bought by mistake a passive buzzer instead of an active buzzer,
which i was intended to connect it,simply,directly to dc voltage source.
What is the simplest methode to active those passive buzzer?

Thanks.

 

There is a discussion on AAC:
http://forum.allaboutcircuits.com/threads/piezo-speaker-how-to-make-it-buzz.26651/

 

If i need to build a circuit with all that components in order that it will pip.
I guess i better make an order,again and order the right active buzzers ones.
Since it is unnecessary thing to do and waste of time and space,while with
active buzzer i just connect to the battery.
It will be,even,cheaper.

Thanks for the link.
