"Playing music like playing the piano." As technology progresses the most electronic devices are designed to be thinner and flatter, but they are losing the tactile feeling when users touch the product and activate the buttons. The design tries to challenge that and takes the inspiration of 'playing piano' to design the buttons. The buttons are extended to be one wave surface of the speaker. The leverage system inside the speaker allows all the buttons can be activated on any points on each button line so the gesture to press the buttons is like playing the piano. The speaker is named as 'VAGUE'. 'vague' in French means 'wave', and 'vague' in English means 'translucent'. The exterior design took the inspiration of these two meanings to create the wave shape for buttons and translucent feeling exterior.
