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.

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.

6. A method comprising:
-
detecting an orientation of a casing of an audio device about an axis relative to a direction of the force of gravity; operating a plurality of acoustic drivers disposed on the casing to form at least a first acoustic interference array in response to the casing being in a first orientation about the axis relative to the direction of the force of gravity; operating the plurality of acoustic drivers to form at least a second acoustic interference array different from the first acoustic interference array in response to the casing being in a second orientation about the axis relative to the direction of the force of gravity; operating a first visual indicator arranged on a first face of the casing to be viewable to a listener at a first listening position in response to the casing being in the first orientation; operating a second visual indicator arranged on a second face of the casing, different from the first face, to be viewable to a listener at the first listening position in response to the casing being in the second orientation; automatically disabling the second visual indicator in response to the casing being in the first orientation; and automatically disabling the first visual indicator in response to the casing being in the second orientation. - View Dependent Claims (7, 14)
