Recyclable Portable stereo speaker for your iPhone made of cardboard with built-in stereo amplifier http://berlinboombox.com
The case is screenprinted with bold graphic art designed by myself.
There is a single, beautiful big knob for power/volume control.
The BerlinBoombox comes as a kit consisting of a die-cut cardboard structure, all electronic parts and 4AA batteries. You can assemble it easily without tools and without any geek knowledge in a couple of minutes.
Use the BerlinBoombox with your iPhone, iPod or any other mp3-player. Connect your device via 3,5mm stereo jack. Unlike most other cardboard speakers on the market this one has a stereo amplifier integrated that provides powerful sound.
Because it is made of cardboard the whole structure can be recycled at the end of the product’s life. This also saves weight which means easy transportation.
Except for the electronic parts, everything is manufactured locally in Berlin.
