Industrial designers John Van Den Nieuwenhuizen from Australia and Vitor Santa Maria from Brazil have collaborated to design the HiddenRadio, which is currently being funded through Kickstarter. Their approach to their work is simple product design that is both innovative and intuitive.
The minimal HiddenRadio & Bluetooth Speaker design connects and captivates the user through its intuitive functionality. When asleep it hides all its functions. To turn it on you simply twist and lift the cap. The further you lift the cap the more internal volume is created and will amplify to over 80dB of crystal clear sound. Although it offers Bluetooth technology, if you don't have a Bluetooth device, a 3.5mm audio input plug is available. The battery life is also an impressive feature, offering over 30 hours of power.
A beautiful, unobtrusive and simple device, which I think is well worth backing.
