How to solve the problem of controls cluttering up electronics devices? Simple: make the device the controller. That's the simple but elegant solution employed by designer Hironao Tsuboi with the equally simply named Vol Speaker concept. The speaker is the knob -- or maybe the knob is the speaker. However you choose to unravel this zen-like chicken and egg riddle, the result is pretty neat.
