Angle is a portable wireless speaker with user controls that have been totally redesigned into a single control that is disguised as a corner of the speaker. The user can use this corner as a dial to change a song or change the volume. Having fully considered the shape and the pattern of traditional speakers, I decided to abandon the typical layout and design of user controls for the Angle speaker. Instead, a brand new way of control is introduced to bring a more intuitive experience and comfortable interaction between the users and the speaker.
