Asymmetrical high-frequency waveguide, 3-axis rigging, and spherical enclosure for surround speakers

1. A speaker assembly for transmitting sound into a venue comprising:

a horn waveguide configured to be asymmetric about one of a vertical axis and horizontal axis of the waveguide to form an asymmetric horn waveguide having two symmetric surfaces about the vertical axis of the horn speaker and two asymmetric surfaces about the horizontal axis of the horn speaker that are separated by adjusting surfaces within the horn to control a Q factor of the waveguide;

a spherical enclosure surrounding the asymmetric horn waveguide to form a horn speaker; and

a three-axis mounting system configured to fix the horn speaker to one of a wall or ceiling surface of the venue, wherein the mounting system facilitates rotating the horn speaker to a location that provides maximum coverage of the venue within a passband of the asymmetric horn waveguide.

2. The speaker of claim 1 wherein a relative size of each surface, an amount of tilt of each surface, and a distance between the adjusting surfaces dictates an optimum projection angle of the horn speaker.

3. The speaker of claim 2 wherein the venue is a large venue comprising one of a cinema, auditorium, theatre, or large listening room, and wherein the upper surface comprises one of a high wall surface or a ceiling of the venue.

4. The method of claim 3 wherein the optimum projection angle for a wall mount comprises an angle that extends close to a bottom side of the horn speaker and is flat across the coverage aiming angle so as to produce a coverage pattern in the venue that softens coverage for a short throw of the speaker and sharpens coverage on a long throw of the speaker in the venue.

5. The method of claim 1 wherein the three-axis mounting system provides pan, tilt, and rotation motion of the horn speaker within a rigid mounting to the upper surface of the venue.

6. The method of claim 5 wherein the three-axis mounting system provides further control of aiming the horn speaker to the location and is fixed in position once set by manual control.

7. The method of claim 1 wherein the audio comprises one of surround sound audio or immersive audio.

8. A method of providing an even audio spectrum during playback in a venue by height speakers, comprising:

providing an asymmetrical horn waveguide that imparts a progressive horizontal coverage width and a narrow vertical dispersion to form a horn speaker; and

providing a three-axis mounting system for the installing the horn speaker to an upper surface of the venue, wherein the mounting system facilitates aiming the horn speaker to a location that provides maximum coverage of the venue within a passband of the waveguide, and provides pan, tilt, and rotation motion of the horn speaker within a rigid mounting to the upper surface of the venue, and further wherein the upper surface comprises one of a high wall location with the horn speaker pointing substantially outwards into the venue, and a ceiling with the horn speaker pointing substantially downwards into the venue.

9. The method of claim 8 wherein the waveguide spreads high frequency content of the audio across a lower side of the horn speaker.

10. The method of claim 8 wherein the venue comprises an enclosed large venue holding a significant number of seats including some seats marginally outside of the location aimed at by the horn speaker.

11. The method of claim 8 wherein the horn speaker pointing substantially outwards into the venue comprises a 60-degree horn speaker, and the horn speaker pointing substantially downwards into the venue comprises an 80-degree horn speaker.

12. A speaker assembly providing an even audio spectrum during playback in a venue by height speakers, comprising:

an asymmetrical horn waveguide that imparts a progressive horizontal coverage width and a narrow vertical dispersion to form a horn speaker; and

a three-axis mounting system for installing the horn speaker to an upper surface of the venue, wherein the mounting system facilitates aiming the horn speaker to a location that provides maximum coverage of the venue within a passband of the waveguide, and provides pan, tilt, and rotation motion of the horn speaker within a rigid mounting to the upper surface of the venue, and further wherein the upper surface comprises one of a high wall location with the horn speaker pointing substantially outwards into the venue, and a ceiling with the horn speaker pointing substantially downwards into the venue.

13. The speaker assembly of claim 12 wherein the waveguide spreads high frequency content of the audio across a lower side of the horn speaker.

14. The speaker assembly of claim 12 wherein the venue comprises an enclosed large venue holding a significant number of seats including some seats marginally outside of the location aimed at by the horn speaker.

15. The speaker assembly of claim 12 wherein the horn speaker pointing substantially outwards into the venue comprises a 60-degree horn speaker, and the horn speaker pointing substantially downwards into the venue comprises an 80-degree horn speaker.

16. The speaker assembly of claim 12 wherein the horn speaker is configured to be asymmetric about one of a vertical axis and horizontal axis of the horn speaker to form an asymmetric horn waveguide having two symmetric surfaces about the vertical axis of the horn speaker and two asymmetric surfaces about the horizontal axis of the horn speaker that are separated by adjusting surfaces within the horn to control a Q factor of the waveguide.
