Abstract
An audio device incorporates a first acoustic driver having a first direction of maximum acoustic radiation and a second acoustic driver having a second direction of maximum acoustic radiation, where the first and second directions of maximum acoustic radiation are not in parallel, and where the audio device employs the first acoustic driver or the second acoustic driver in acoustically outputting a sound of a predetermined range of frequencies in response to the orientation of the casing of the audio device relative to the direction of the force of gravity.
