iPhone Amplifier Case for Bicycles

Horn Bike

The Horn Bike for the iPhone 4/4S is an amplifier case for bicycles. The back of the silicone cover is attached to the handlebar with a Velcro fastener. The integrated horn uses the principle of a gramophone horn to amplify voice and music, increasing volume by 13 db. It does not require an energy source and is made of environmentally friendly, recyclable material.
