Cool. I did a little research. I can't find any reference to the Newton's
speaker and amplifier specs so if anybody has any leads I'd appreciate it.

Rat Shack has a few micro speakers:

These are 30mm diameter and have frequency response of 500-12Khz -- I need
to measure the Newt speaker to see how big it is. It might be smaller than
that. They have a 20mm one also but the frequency response is 0-5Khz, so it
probably wouldn't sound any better than the built-in one.

Then there's Digikey. The have several "micro speakers" listed at:

including one 20mm Panasonic with "Full Range" frequency, whatever that is.
Sounds promising....

Daniel Padilla's web site shows how he easily wired a headphone jack in
series with the Newton speaker. Looks like it could be done fairly simply.
The only thing I worry about is how to mount the jack internally. Also, how
do you drill a hole in the Newton's case cleanly?
