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

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?

How about an old mobile phone speaker they are about that size or smaller or you could try MAPLINS in the UK
Greeting cards featuring sound.
