Techniques for localized perceptual audio
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.
1. A video display apparatus, the apparatus comprising:
a video display;
a first row of at least five audio transducers above the video display, the audio transducers of the first row being spaced farther apart at a periphery of the first row; and
a second row of at least five audio transducers below the video display, the audio transducers of the second row being spaced farther apart at a periphery of the second row,
wherein a first audio transducer of the first row and a first audio transducer of the second rows form a first column to concertedly produce an first audible signal, the first audible signal being weighted between the audio transducers of the first column to correspond to a first visual cue position,
wherein a second audio transducer of the first row and a second audio transducer of the second rows form a second column to concertedly produce a second audible signal during simultaneous reproduction of the first audible sound by the first column, the second audible signal being weighted between the audio transducer of the second column to correspond to a second visual cue position.
2. The apparatus of claim 1 wherein the video display, first row and second row are integrated with a single form factor.
3. The apparatus of claim 1 further comprising an input for receiving a center channel audio signal for a surround sound system,
wherein the first and second rows only reproduce the center channel audio signal.
4. The apparatus of claim 1 further comprising a processor to calculate weights for the audio transducers of the first column for the first audible signal from metadata indicating the first visual cue position.
5. The apparatus of claim 1 further comprising a first surround loudspeaker and a second surround loudspeaker.
6. The apparatus of claim 1 wherein the first row of the at least five audio transducers comprises audio transducers of differing size.
7. The apparatus of claim 1 wherein the first row of the at least five audio transducers comprises audio transducers having differing frequency range performance.
8. The apparatus of claim 1 wherein the first and second visual cue positions are associated with different programs of media content.
9. The apparatus of claim 8 the second visual cue position is within a picture-in-picture.
