1. An audio device comprising:
- a casing comprising an array of acoustic drivers, each driver operating in a first frequency range and located along an elongate axis of the casing, the array configured to form a plurality of acoustic interference arrays operating over the first frequency range, each acoustic interference array being associated with one of a plurality of audio channels, the casing positionable between a first orientation and a second orientation different from the first orientation;
an orientation input device to detect the orientation of the casing relative to the direction of the force of gravity;
a processing device; and
a storage accessible by the processing device in which is stored a control routine comprising a sequence of instructions that when executed by the processing device, causes the processing device to;
monitor the orientation input device to determine the orientation of the casing;
in response to the casing being in the first orientation, operate the acoustic drivers to form a first acoustic interference array by utilizing a plurality of coefficients to configure a plurality of filters; and
in response to the casing being in the second orientation, operate the acoustic drivers in a manner different from the first acoustic interference array by changing one or more of the coefficients to re-configure one or more of the filters.

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.
