Using passive amplification alone, designer Tristan Zimmermann came up with the Phonofone II, which transforms a personal music player into a sort of mini victrola.

From Science & Sons:

[...] Without the use of external power or batteries, the Phonofone [...] exploits the virtues of horn acoustics to boost the audio output of standard earphones to up to 55 decibels* (or roughly the maximum volume of laptop speakers)

This would fit nicely on top of my full-size victrola at home. (Via Veer.)
