Curiously dubbed "YO," this attractive iPod and MP3 stereo speaker dock is a concept by American-born designer Victor Vetterlein. The speakers are detachable and wireless (as well as waterproof), and charge at the dock just like an MP3 player would. The odd shape of the speakers is to help produce a more pronounced, directional sound. (How the speakers stay upright away from the dock is anyone's guess.)

Even curiouser, Vetterlein intends for the unit to be charged by a "renewable energy source such as solar power, wind power, or hydroelectricity." Either he means that's how he wants the energy to be gathered, or he still has some parts to add to it — like some solar panels, or, uh, a wind turbine.

Introducing 'YO' - an iPod and MP3 stereo speaker dock by Victor Vetterlein

YO is a rechargeable and wireless stereo speaker docking station for digital audio players. The system is portable, waterproof, and suitable for indoor and outdoor use.

Inside the dock base are lithium-ion (rechargeable) batteries that are capable of powering the stereo system for hours when the unit is disconnected from a power source. The design intention is that a renewable energy source such as solar power, wind power, or hydroelectricity charges the battery packs when the stereo is not in use.

The speakers also contain lithium-ion batteries in their base, and recharge when placed in the stereo base portals. The batteries also provide high-density ballast enabling the speakers to stand upright when removed from the charging ports.

The speaker enclosure is designed to amplify sound. The speakers are mounted in the rear of the speaker housing. Similar to a megaphone, the front portion of the speaker enclosure is extruded to increase and direct sound.

Two removable rods are mounted between the stereo speakers to stabilize the stereo assembly and provide a lifting handle when the unit is transported.
