Abstract:
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, at least a portion of the plurality of acoustic drivers configured to form a plurality of acoustic interference arrays; a first acoustic reflector disposed on the casing to partially overlie a first acoustic driver of the plurality of acoustic drivers, and to reflect sounds acoustically output by the first acoustic driver within a first predetermined range of frequencies such that the first acoustic reflector and the first acoustic driver cooperate to redirect a radiation pattern associated with sounds output by the first acoustic driver within the first predetermined range of frequencies; and a second acoustic reflector disposed on the casing to partially overlie a second acoustic driver of the plurality of acoustic drivers, and to reflect sounds acoustically output by the second acoustic driver within a second predetermined range of frequencies such that the second acoustic reflector and the second acoustic driver cooperate to redirect a radiation pattern associated with sounds output by the second acoustic driver within the second predetermined range of frequencies; and wherein: in response to the casing being in the first orientation, the portion of the plurality of acoustic drivers configured to form a plurality of acoustic interference arrays form at least a first acoustic interference array; and in response to the casing being in the second orientation, the portion of the plurality of acoustic drivers configured to form a plurality of acoustic interference arrays form at least a second acoustic interference array different from the first acoustic interference array.
