In actuality...all the I-Pod does is play/record sound (and not very well due to

suggested (great idea), a wireless transmitter that could then relay the signal
to a good powerful receiver. Any suggestions (brand/model) along either line?

Nothing specific. Google for "battery powered speaker". Lots of
hits.

I would be tempted to suggest a battery power boom box or karaoke box.
What I'm worried about it that someone is going to run it with the
stethescope while charging the internal batteries. Too big a risk, so
we're back to wireless again.

Look at the wireless microphones available for persentations. They're
usually in the commercial sound business sites. While most have a
built in microphone, there are a few that allow external mics. They're
unfortunately kinda pricy. You might do better with wireless speakers
that are made to run off a hi-fi. You didn't supply any interface
specifications, but if the stethescope puts out home hi-fi line levels
(about 0dBm), one of these should work.

I gotta run, but I'll see if I can find something later today.


This would hopefully suit you, they are available in Walmart and work
quite well, I had one on my mp3 player in my car for ages due to my CD
player being bust. All you need is your radio boombox tuned to the
transmit signal.
