First Claim
Patent Images
1. A television, comprising:
- a flat panel display device for presenting video images;
a housing for supporting the flat panel display device;
a first acoustic volume located substantially (a) inside the housing, and (b) behind the display device; and
two or more acoustic drivers for acoustically energizing the acoustic volume, the drivers being positioned such that acoustic energy put into the acoustic volume from the drivers is substantially additive and vibrational energy from the drivers substantially cancels out.

Abstract
A television includes a flat panel display device for presenting video images, a housing for supporting the flat panel display device, and a first acoustic volume located substantially (a) inside the housing, and (b) behind the display device. Two or more acoustic drivers are provided for acoustically energizing the acoustic volume. The drivers are positioned such that acoustic energy put into the acoustic volume from the drivers is substantially additive and vibrational energy from the drivers substantially cancels out.

9. A television, comprising:
-
a flat panel display device for presenting video images; a housing for supporting the flat panel display device; an acoustic volume located substantially (a) inside the housing, and (b) behind the display device; and two or more acoustic drivers which acoustically energize the acoustic volume, wherein a maximum acoustic output of the drivers measured in an anechoic chamber at one meter from a center of a surface of the display device from which video images are projected averages at least about 80 dBSPL over a range from about 40 hz to about 80 hz. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A television, comprising:
-
a flat panel display device for presenting video images; a housing for supporting the flat panel display device; a waveguide located substantially (a) inside the housing, and (b) behind the display device; and two or more acoustic drivers for acoustically energizing the waveguide, wherein the housing is less than about 200 mm thick in a direction that is substantially normal to a surface of the display device from which video images are projected. - View Dependent Claims (29, 30, 31, 32, 33, 34)
