Altec Lansing has introduced their IMT237-Orbit MP3 portable audio speaker in Korea. It’s powered by 3 AAA batteries that will give you up to 24 hours of non-stop audio playback.

All I ask is that you have good taste in music if you absolutely have to use this in public with your portable media player or notebook. We don’t know what kind of power the speaker has, but obviously it won’t be damaging many eardrums.
