1. An audio system for a vehicle having a plurality of seat positions, said audio system comprising:
- a plurality of sources of music audio signals, wherein music content differs among the music audio signals from different said sources;
a respective directional loudspeaker array mounted at each seat position and coupled to the plurality of sources so that the music audio signals drive the respective directional loudspeaker array to radiate acoustic energy;
control circuitry that is coupled to the plurality of sources, wherein any of said sources are selectable to any of said seat positions through the control circuitry in response to an input received by the control circuitry from an occupant of the vehicle; and
processing circuitry coupled to the control circuitry and between the plurality of sources and each said respective directional loudspeaker array, wherein, for each first said seat position independently of each other said seat position and responsively to the control circuitry, the processing circuitry directs, to the respective directional loudspeaker array mounted at the first seat position, music audio signals from a said source that is selected by the input.

Abstract
An audio system for a vehicle having a plurality of seat positions includes a plurality of sources of audio signals. Respective directional loudspeaker arrays are mounted at the seat positions. Any of the sources are selectable to any of the seat positions through control circuitry in response to an input from an occupant of the vehicle. Processing circuitry is coupled to the control circuitry and is between the plurality of sources in each respective directional loudspeaker array.
