Abstract
An audio device includes a housing having first and second support surfaces for supporting the device at different orientations relative to the surface on which the device is placed, a driver to output sound in a radiating pattern associated with a first axis of the driver, and an orientation sensor to detect a direction of a force of gravity. A control circuit coupled to the driver and the orientation sensor determines the direction of the force of gravity relative to the first axis and whether the first axis is oriented to one of a first angle of elevation associated with physically supporting the device by the first surface and a second angle of elevation associated with physically supporting the device by the second surface. The circuit can alters the output by the driver based on the first axis being oriented to the first or second angles of elevation.
