In some embodiments, a processing module may include spatial processor spatially processes surround-left and surround-right channel signals and front-left and front-right channel signals and combines the spatially-processed signals for providing to drivers of center speaker after crosstalk cancellation and combining with a center-channel signal. In some embodiments, the processing module may include circuitry to cause the spatial processor to refrain from spatially processing either the front-left and front-right channel signals when front-left and/or front-right speakers are connected. | 2008-11-06 |
20080273722 | DIRECTIONALLY RADIATING SOUND IN A VEHICLE - A vehicle loudspeaker system in a vehicle including directional loudspeakers. One directional loudspeaker radiates sound at a first seating position and another loudspeaker radiates sound at a second seating position. The directional loudspeakers may be used with other vehicle loudspeakers to control spatial perceptions. | 2008-11-06 |
