Abstract:
A directivity adjustment device that maintains a constant direct-to-reverberant ratio based on the detected location of a listener in relation to the speaker array is described. The directivity adjustment device may include a distance estimator, a directivity compensator, and an array processor. The distance estimator detects the distance between the speaker array and the listener. Based on this detected distance, the directivity compensator calculates a directivity index form a beam produced by the speaker array that maintains a predefined direct-to-reverberant sound energy ratio. The array processor receives the calculated directivity index and processes each channel of a piece of sound program content to produce a set of audio signals that drive one or more of the transducers in the speaker array to generate a beam pattern with the calculated directivity index.

Claim (Index 26):
A method for driving a speaker array to output audio content to a listener, the method comprising:\n detecting a first distance of the listener from the speaker array; driving the speaker array to emit a first beam pattern having a first beam pattern width, wherein the first beam pattern provides a predefined sound pressure at the first distance; detecting a second distance of the listener from the speaker array, wherein the second distance is less than the first distance; and driving the speaker array to emit a second beam pattern having a second beam pattern width, wherein the second beam pattern width is greater than the first beam pattern width, and wherein the second beam pattern provides the predefined sound pressure at the second distance.
