designer's own words:This concept is a result of experimenting with running small inexpensive drivers, passively, off the headphone jack of an mp3 player. The form has been simply based on a three dimensional interpretation of the icon we all recognise as indicating volume. A process of quick paper modeling, involving a high number of iterations was employed to develop a form that most closely resembled this icon as people see it. The simple aesthetic of the paper models proved so appealing that the final working prototype was designed to resemble them in surface finish and detailing. A flat surface is cut into the back of the cylinder in line with the front edge to keep the speaker unit steady. Both passive and amplified USB powered versions are proposed.
