Abstract

A system for enhancing sound includes a support structure and one or more panels forming a panel structure. The panel structure defines a first and second portion of an oblong enclosure, both forming an approximated double ellipse profile, comprising a material having a sound reflective surface, and held by the support structure. The first portion extends between a first area proximate a first speaker driver and a second area proximate the listener. The second portion extends between a third area proximate a second speaker driver and a fourth area proximate the listener. The two portions are shaped such that sound waves emitted laterally from the first and second speaker drivers are reflected and focused toward the listener as spatially localized three-dimensional surround sound without electronically manipulating the sound signals and while reflectively reducing the effect of crosstalk.

Claims (31)

1. A system for enhancing sound provided by at least a pair of speaker drivers relative to a listener, comprising:

a support structure; and

one or more panels forming a panel structure, the panel structure defining:

a first portion of an oblong enclosure that forms an approximated double ellipse profile, comprising a material having a sound reflective surface, held by the support structure, and extending between a first area proximate a first speaker driver and a second area proximate the listener, wherein the first portion of the oblong enclosure forms a first part of the approximated double ellipse profile; and

a second portion of the oblong enclosure that forms the approximated double ellipse profile, comprising a material having a sound reflective surface, held by the support structure, and extending between a third area proximate a second speaker driver and a fourth area proximate the listener, wherein the second portion of the oblong enclosure forms a second part of the approximated double ellipse profile,

wherein the first portion and the second portion are shaped such that sound waves emitted laterally from the first speaker driver and the second speaker driver are reflected and focused toward the listener as spatially localized three-dimensional surround sound without electronically manipulating the sound signals and while reflectively reducing the effect of crosstalk.

2. The system of claim 1 , wherein the oblong enclosure is elongated and has a width that is longer than a length thereof, and wherein the first portion and the second portion are symmetrically arranged about a plane with which the length of the oblong enclosure is aligned.

3. The system of claim 2 , further comprising a template having a first side and an opposing second side, the opposing second side configured to be disposed along the ground.

4. The system of claim 3 , further comprising a speaker positioning system including two or more points that correspond to a plurality of speaker locations, wherein the speaker positioning system at least one of (a) is disposed along the first side of the template and (b) extends at least partially between the first side and the opposing second side of the template.

5. The system of claim 3 , further comprising a panel positioning system including one or more arcs that define one or more positions for the first portion and the second portion, wherein the panel positioning system at least one of (a) is disposed along the first side of the template and (b) extends at least partially between the first side and the opposing second side of the template.

6. The system of claim 1 , wherein the first portion and the second portion are substantially symmetrical in shape and position.

7. The system of claim 1 , wherein the first portion is curved to reflect sound waves emitted at a plurality of different lateral angles relative to a sound axis of the first speaker driver;

wherein the curvature of the first portion directs a plurality of captured sound waves to the listener via the reflection;

wherein the second portion is curved to reflect sound waves emitted at a plurality of different lateral angles relative to a sound axis of the second speaker driver;

wherein the curvature of the second portion directs a plurality of captured sound waves to the listener via the reflection.

8. The system of claim 1 , wherein the first portion is curved inward toward the listener in at least one section to reflect sound waves emitted at a plurality of different vertical angles relative to a sound axis of the first speaker driver;

wherein the curvature of the first portion directs a plurality of captured sound waves to the listener via the reflection;

wherein the second portion is curved inward toward the listener in at least one section to reflect sound waves emitted at a plurality of different vertical angles relative to a sound axis of the second speaker driver;

wherein the curvature of the second portion directs a plurality of captured sound waves to the listener via the reflection.

9. The system of claim 1 , wherein the panel structure comprises one panel, wherein the first portion and the second portion are integrally formed and define a single unitary body.

10. The system of claim 1 , wherein the panel structure comprises a first panel and a second panel not integrally formed with the first panel, wherein the first panel comprises the first portion and the second panel comprises the second portion.

11. The system of claim 1 , wherein the first portion and the second portion are joined behind the listener's position such that waves are reflected to the listener from behind the listener.

12. The system of claim 1 , wherein at least one of the first speaker driver and the second speaker driver comprise a tweeter, wherein the first portion extends vertically from a distance at least 0.2 meters below the tweeter to a distance at least 0.2 meters above the tweeter, wherein the second portion extends vertically from a distance at least 0.2 meters below the tweeter height of the pair of speaker drivers to a distance at least 0.2 meters above the tweeter height of the pair of speaker drivers.

13. The system of claim 1 , further comprising:

a first sound shaper panel that extends substantially horizontally from a surface of the first portion, the first sound shaper panel positioned to reflect directional or spatial localizing sound frequencies toward the listener that were emitted at vertically offset angles from a tweeter axis of the first speaker driver;

a second sound shaper panel that extends substantially horizontally from a surface of the second portion, the second sound shaper panel positioned to reflect sound waves toward the listener that were emitted at vertically offset angles from the tweeter axis of the second speaker driver.

14. The system of claim 13 , wherein at least one of the first sound shaper panel and the second sound shaper panel are curved inward toward the listener.

15. The system of claim 13 , wherein the panel structure and at least one of the first sound shaper panel and the second sound shaper panel are integrally formed and define a single unitary body.

16. The system of claim 1 , further comprising:

a rail having one or more attachment mechanisms configured to secure the rail to at least one of a ceiling and a floor; and

a support element coupled to the rail and holding the panel structure in a desired vertical position and a desired horizontal position.
