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 first acoustic driver disposed on the casing and having a first direction of maximum acoustic radiation;

    a second acoustic driver disposed on the casing and having a second direction of maximum acoustic radiation; and

    wherein;

    the first direction of maximum acoustic radiation is not parallel to the second direction of maximum acoustic radiation;

    a sound is acoustically output by the first acoustic driver in response to the casing being in the first orientation; and

    the sound is acoustically output by the second acoustic driver in response to the casing being in the second orientation.
