Abstract
A device that provides an audio output includes a speaker array mechanically fixed to the device. The speaker array includes at least three speakers. An orientation sensor detects an orientation of the speaker array and provides an orientation signal. An audio receiver receives a number of audio signals that include spatial position information. An audio processor is coupled to the speakers, the orientation sensor, and the audio receiver. The audio processor receives the audio signals and the orientation signal, and selectively routes the audio signals to the speakers according to the spatial position information and the orientation signal such that the spatial position information is perceptible to a listener. The orientation signal may be provided by a compass, an accelerometer, an inertial sensor, or other device. The orientation signal may be provided according to selection of display orientation, shape of touch input, image recognition of the listener, or the like.
