Techniques for localized perceptual audio
First Claim
1. A method for audio reproduction, the method comprising:
- selecting audio transducers of a first column to correspond to a first visual cue position according to column snapping;
selecting audio transducers of a second column to correspond to a second visual cue position according to column snapping, wherein the audio transducers of the first and second columns are arranged in a first row and a second row, and wherein at least one of the selected audio transducers of the first column differs from the selected audio transducers of the second column;
calculating first weight factors based on the selected audio transducers of the first column and the first visual cue position, wherein the first weight factors correspond to a vertical position of a perceptual origin for the first visual cue position;
calculating second weight factors based on the selected audio transducers of the second column and the second visual cue position, wherein the second weight factors correspond to a vertical position of a perceptual origin for the second visual cue position;
producing a first audible signal using the first weight factors applied to the selected audio transducers of the first column, the first audible signal being weighted between the selected audio transducers of the first column to correspond to the first visual cue position; and
producing a second audible signal during simultaneous reproduction of the first audible signal by the first column using the second weight factors applied to the selected audio transducers of the second column, the second audible signal being weighted between the selected audio transducers of the second column to correspond to the second visual cue position,wherein a first listener position has substantially equal first path lengths to the selected audio transducers of the first column, and wherein a second listener position has substantially equal second path lengths to the selected audio transducers of the first column.

Abstract
Audio perception in local proximity to visual cues is provided. A device includes a video display, first row of audio transducers, and second row of audio transducers. The first and second rows can be vertically disposed above and below the video display. An audio transducer of the first row and an audio transducer of the second row form a column to produce, in concert, an audible signal. The perceived emanation of the audible signal is from a plane of the video display (e.g., a location of a visual cue) by weighing outputs of the audio transducers of the column. In certain embodiments, the audio transducers are spaced farther apart at a periphery for increased fidelity in a center portion of the plane and less fidelity at the periphery.
