Abstract:
An audio system for a vehicle includes a directional loudspeaker that is mounted to a vehicle seat. The directional loudspeaker radiates a first channel audio signal so that the direction toward an intended location of a first ear position of an occupant of the vehicle seat is a high radiation direction and radiates a second channel audio signal 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 radiates at least one of the first channel audio signal and the second channel audio signal. Signal processing circuitry modifies (e.g., delays) the first channel audio signal to at least one of the directional loudspeaker and the forward mounted loudspeaker to cause one of those speakers to dominate spatial perception.
