Abstract:
1. An audio system for a vehicle, 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 non-surround channel audio 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 for radiating a second non-surround channel audio 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 non-surround channel audio signal and the second non-surround channel audio signal; signal processing circuitry for modifying the first non-surround channel audio signal to at least one of the directional loudspeaker and the forward mounted loudspeaker to cause one of the directional loudspeaker or the forward mounted speaker to dominate spatial perception, wherein the signal processing circuitry includes circuitry for delaying the first non-surround channel audio signal to one of the directional loudspeaker and the forward mounted loudspeaker.
