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;
selecting audio transducers of a second column to correspond to a second visual cue position, 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;
producing a first audible signal, 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, 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.

11. A video display apparatus, the apparatus comprising:
-
a video display; audio transducers arranged in a first row above the video display and a second row below the video display; and a processor, wherein the processor is configured to select, from the audio transducers in the first row and the audio transducers in the second row, audio transducers of a first column to correspond to a first visual cue position, wherein the processor is configured to select, from the audio transducers in the first row and the audio transducers in the second row, audio transducers of a second column to correspond to a second visual cue position, wherein at least one of the selected audio transducers of the first column differs from the selected audio transducers of the second column, wherein the selected audio transducers of the first column produce a first audible signal, the first audible signal being weighted between the audio transducers of the first column to correspond to the first visual cue position, wherein the selected audio transducers of the second column produce, during simultaneous reproduction of the first audible signal by the first column, a second audible signal, the second audible signal being weighted between the audio transducers of the second column to correspond to the second visual cue position, and 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
