Patent ID: 8325936

Claim:
An audio system comprising: a directional loudspeaker mounted to a vehicle seat, behind an intended location of the head of an occupant of the vehicle seat and substantially equidistant from an intended position of the two ears of the occupant of the vehicle seat; the directional loudspeaker for radiating a first channel signal directionally so that the direction toward an intended location of a first ear position of the occupant of the vehicle seat is a high radiation direction and radiating a second channel signal directionally so that the direction toward an intended location of a second ear position of the occupant of the vehicle seat is a high radiation direction; a forward mounted loudspeaker mounted forward of the directional loudspeaker for radiating at least one of the first channel and the second channel; signal processing circuitry for modifying an audio signal to at least one of the directional loudspeaker and the forward mounted loudspeaker to modify spatial perception wherein the signal processing circuitry includes circuitry that modifies audio signals so that the directional loudspeaker dominates left/right spatial perception and the forward mounted speaker dominates front/rear spatial perception.
