mini speaker

[skimask]

I have a PIC app which needs a speaker less that 12 mm in diameter. It is using a voice chip and needs to reproduce intelligible audio loud enough to understand a few feet away. Any ideas? I am working from 3 volts so need something fairly efficient.
Thanks,
Ron

I searched Digikey (as I'm sure you did), I would've figured there would have been more out there in terms of small speakers.
But...a thought...how about tearing apart a few cheap headphones and using those speaker elements?
