The Cube Bluetooth Speaker is an easy-to-control digital smart product design. There is a magnetic ball which is like a button at the top of the speaker. You can adjust the volume by rolling the ball. By pressing the ball down 360 degrees without dead angles for a short time, you can pause or play music, and turn it on and off by long-pressing, the indicator light is cleverly hidden in the broadcast hole, not abrupt. ​
​These operating interfaces are not only intuitive, anyone can understand how to use it when they see it, and when the user adjusts the volume by moving the magnetic ball, it can also provide tactile and visually different pleasures.
