Abstract
Audio speaker systems and methods are provided to detect movement of the speaker system or other device. An audio program content signal is converted into an acoustic signal, and the acoustic signal causes an echo signal. The echo signal is received and a relationship of the echo signal to the audio program content signal is quantified. A quantified value is compared to a stored quantified value and, based upon the comparison, a change in physical position is selectively indicated.
