Abstract
An audio device includes a casing configured for operation in a first orientation and a second orientation different from the first orientation, an orientation input device disposed on the casing to detect an orientation of the casing relative to the direction of the force of gravity, and a plurality of acoustic drivers disposed on the casing and operable to form a plurality of acoustic interference arrays, each of which is associated with one of a plurality of audio channels. The acoustic drivers of the audio device operate in a first frequency range and modify at least one of the acoustic interference arrays in response to a change in the orientation detected by the orientation input device.
