Some interface elements of our smartphones and tablets are so effective at conveying their intended functionality that they rapidly became ubiquitous and immediately recognizable. The iPhone toggle button, with its circular on/off slider locked into an inset slot, is a prime example of that. A new concept by the designer Yongha Yang tries to bring the popular toggle button into the real world as an electronic object, the ONOFF tabletop speaker, that mixes shape and function in an original way. 

The circular button itself is the actual speaker and it’s inserted into a capsule-shaped external frame. If it sits on the left, the device is turned off. Conversely, when it’s shifted to the right, the device is on, exactly like you would expect for a feature turned on or off by a 2D interface toggle. The designer has added a literal spin to the concept, though: the main “button” is not static, but it rotates to turn volume up and down, with three LEDS in the center indicating the volume’s level. The ONOFF is unfortunately just a concept, for now, with no plans to turn it into a real physical product.
