Shaker type audio player to shake and sing "Sansa Shaker"

It is a SanDisk made audio player "Sansa Shaker" whose songs change by shaking the main body. There is an SD card slot, with 512 MB of SD card. Speakers are also equipped so that everyone in the room can enjoy music.

Driven by a single AA battery, the price is $ 39.9 (about 4800 yen). Since there are two headphone jacks unusually, it seems that you can listen to music with up to two people without using the speaker function.

I shake the body from around 5 minutes 26 seconds and I am selecting music.
