The 'Cloud' is a domestic portable interactive speaker which could create percussion sound by touching the bubbles. It could be matched up as a pair or group and synchronised to play music or play as a small percussion band. Cloud-like soft bubbles attract touch and tap, and the simple and gentle design language eliminates the user’s tension on the professional instrument. Tap the bubble to make a sound of percussion, it is easy to create a beat, and the sense of achievement attracts users to explore it further. Whether for listening or playing, the 'Cloud' can play its perfect function.
