Using piezo buzzers from birthday cards and muiscal ties as mp3 speakers. How to wire 2 in series and amplify etc?
After a while i tried a new wire and i got it to work, but it's very quiet. So i thought i would try and wire up the 2nd one to see if it would make it louder, but i couldn't get any sound out of it.
THis is what the 1st speaker wired up looks like:
My first question is can i simply wire the other speaker onto the same wire as this one is currently or do i have to add another set of wires( split them) so there is 2 set of wires (1xred and 1xbrown)?
secondly before i cut off the speaker (in it's original christmas song buzzer circuit thing) it was considerably louder, is this because there is an amplification part to this circuit- if so can i take it out?
Im guessing not looking at it: this is the original circuit: https://www.instructables.com/files/deriv/F94/NO2I/FWMO31V2/F94NO2IFWMO31V2.SQUARE.jpg
