The Shake MP3 player by Kenneth Tay makes use of kinetic energy to keep the batteries charges, similar to modern timepieces. With the hold button switched on, jerk it a few times to get the juice. Yea I just said that. Conversely if you leave the hold switch off, the jerking shaking pauses/plays music.

Texts from the designer:
An electromagnetic coil is connected to the battery, converting kinetic energy into electrical energy that charges the battery.
The player connects to the computer via USB cable through the headphone jack, facilitating the transfer of songs as well as the conventional method of charging.
