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;

    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;

    in response to the casing being in the first orientation, operate the plurality of acoustic drivers to form at least a first acoustic interference array by selecting a first plurality of coefficients to configure a plurality of filters; and

    in response to the casing being in the second orientation, operate the plurality of acoustic drivers to form at least a second acoustic interference array different from the first acoustic interference array by selecting a second plurality of coefficients to configure the plurality of filters.
