First Claim
Patent Images
1. Apparatus comprising:
- a first directional loudspeaker for directionally radiating sound toward a first seating position in a vehicle at a first volume,a second directional loudspeaker for directionally radiating sound toward a second seating position in the vehicle at a second volume; and
at least one ofvolume control circuitry, for controlling the first volume independently of the second volume;
dynamic volume control circuitry, for dynamically controlling the first volume independently of the second volume;
orequalization circuitry, for equalizing the sound radiated toward the first seating position independently of the sound radiated toward the second seating position.

Abstract
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.
