Orientation-responsive use of acoustic reflection
First Claim
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.

Abstract
An audio device incorporates first acoustic driver at least partially overlain by a first acoustic reflector to define a first effective direction of maximum acoustic radiation and a second acoustic driver at least partially overlain by a second acoustic reflector to define a second effective direction of maximum acoustic radiation, wherein when the audio device is positioned in a room such that the direction of maximum acoustic radiation of the first acoustic driver is substantially perpendicular to the direction of the force of gravity, the first effective direction of maximum acoustic radiation is bent more towards a listening position at which a listener is expected to be located than the first direction of maximum acoustic radiation and away from a floor, and the second effective direction of maximum acoustic radiation is bent more towards the listening position than the second direction of maximum acoustic radiation and away from a wall.
