The original speaker is from FOSTER, made in china.
Diameter is 20 mm.
Impedance 8 Ohms.
Power rating 0.8 Watts.
The thing is only 3 mm thick.
But before you proceed reed my previous message and the one from Marco
Mailand ...

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:
http://www.digikey.com/scripts/us/dksus.dll?Criteria?Ref=89403&Cat=26936258
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?
