where can i get smallish but loud cheap speakersabout say 2cm in diameter? Answered

I need some small speakers for a portable speaker project, i no yes it does sound like every other portable speaker project but it is slightly different. So the speakers need to be smallish about 2 cm across but still quite loud, any easy places to get them from?

Using piezo buzzers from birthday cards and muiscal ties as mp3 speakers. How to wire 2 in series and amplify etc?

Ok so i want to make this instructable: https://www.instructables.com/id/Make-an-iPod-Speaker-from-a-Hallmark-Music-Card/ i look around for a musical card but i can't find one. But i do find some miscal things taken out of christmans ties n such and also some old piezo buzzers. I figured these would work the same after tryin for a while with some headphone wires i gave up trying to wire them up as my headphone wires had 2 brown, 1 red and 1 green wire and in the instructable it only had 2; 1 brown and 1 red. 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:https://www.instructables.com/files/deriv/FZ1/3ZYR/FWMO31UR/FZ13ZYRFWMO31UR.SQUARE.jpgMy 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.jpgI know that was long winded but thanks to anyone hwo gives their time to try and helpMdog
