1. An audio device comprising:

  • a casing rotatable about an axis between a first orientation and a second orientation different from the first orientation;

    an orientation input device disposed on the casing to enable determination of an orientation of the casing relative to the direction of the force of gravity;

    a plurality of acoustic drivers disposed on the casing and operable to form a plurality of acoustic interference arrays; and

    a first visual indicator arranged on a first face of the casing and a second visual indicator arranged on a second face of the casing different from the first face, the first visual indicator configured to be viewable to a listener at a first listening position when the casing is positioned in the first orientation, the second visual indicator configured to be viewable to a listener at the first listening position when the casing is positioned in the second orientation,wherein;

    in response to the casing being in the first orientation, the plurality of acoustic drivers are operated to form at least a first acoustic interference array;

    in response to the casing being in the second orientation, the plurality of acoustic drivers are operated to form at least a second acoustic interference array different from the first acoustic interference array;

    the audio device is configured to disable the second visual indicator in response to the casing being in the first orientation; and

    the audio device is configured to disable the first visual indicator in response to the casing being in the second orientation.
