When past have met future, we created Megafone, amplifier which does not require electricity for its operation. It combines centuries-old acoustic megaphone design with modern materials and 3D printing. The shape is accomplished by laying down layer after layer of material to get this very attractive megaphone. It is printed with a mixture of biodegradable plastic and wood and is compatible with iPhones and new models of Samsung. The passive amplifier works exclusively by mechanic, employing geometry to optimize performance, creating a pleasant and immersive listening experience.
