The form of the Megaphone (roughly $520) by en&is is designed to amplify and optimize the best sound output. It uses natural acoustics to amplify the existing speaker on an iPhone. The designers wanted to juxtapose the electronic complexity of the iPhone with the low-tech simplicity of a ceramic horn. The amplifier is based on a thin wooden frame that allows the object to float off the table. This in order to increase the vibration of the object and to optimize the emission of sound.
