Concept iPhone Speaker dock
This is an idea for a speaker dock unit for iPhone/iPod. It is designed to be portable with or without power. The unit will have your standard connectors to dock the phone for charging and playing sound through the powered speakers.
As well this unit can be taken where there is no power to be used for listening music or whatever you want. There is a spring loaded door/slot behind the connector slot where the iDevice can be placed. This allows the device to enter behind the speakers and directly into the echo chamber. From there the sound can be heard through the megaphone style echo chamber all without the need for power.
