Abstract
An audio output device comprises a loudspeaker and, four stem control inputs substantially even spaced on the upper surface of a housing. The stem control inputs are each divided into four segments, each comprising a touch sensor and an illumination unit. Each stem control input is associated with a different stem in an audio track for playback via the loudspeaker. Touching the segments of each stem control input results in the touch being detected and a touch signal being output by the respective segment. In response to a touch signal, the associated illumination unit is togged on/off and a property of the associated stem is varied during playback by loudspeaker.
