Stick it on your desk, fridge, floor, cupboard, car bonnet, whatever, and prepare to be amazed I-bird is completely wireless, strong sucker stay outside, built-in lithium ion rechargeable battery and a built-in Mp3 and 2G memory chips, no longer an external audio input can be hard suction in any plane, at any time listening to music, and make music through windows, doors, desktop, and other objects to increase physical fun.

A kind of special speaker, but there is no sound device inside. It depends on a high-technical crystal to shake any hard surface, like wood, glass, wall, stone and so on, and make hard surface send out the music.
