"Green Amp is an eco-friendly sound amplifier built onto a sturdy case for the iPhone 4 and 4s. The purpose of Green Amp is to provide much louder phone volume. Most sound amplifiers have wiring and use electricity but not Green Amp. Green Amp is simple, eco-friendly, portable, cheap, and provides at least twice the volume then a regular phone. Green Amp uses only the energy of sound already being produced by your phone. It works quite a lot like car headlights. Behind a headlight is a concave mirror that reflects escaping light into a focal point. With Green Amp, all escaping sound waves are redirected and put to use, wasting zero energy. The case has ribs that fold and unfold. resembling an armadillo. It allows it to be compact enough to fit in your pocket, but still provide a concave surface when opened to reflect the sound waves toward you."
