[sdiy] Using a phone earpiece as a speaker???

[harrybissell at copper.net]

You should be able to activate the earpiece...
its is essentially a speaker. It has two terminals
you can hook to an amplifier...

The 'old school' mouthpiece is a CARBON
microphone... it needs to have a DC voltage
imposed across it (how much ... don;t know)
and then AC couple the input in to your
uhhh... input ???
