Private audio system for a 3D-like sound experience for vehicle passengers and a method for creating the same

A method of providing a private audio system for a vehicle passenger the private audio system comprising one or more acoustic sound emitters configured to transmit sound from an audio source in an audio frequency range, one or more ultrasonic speakers configured to transmit an audio beam from an audio source, wherein the audio beam is orientable relative to the passenger, one or more passenger monitoring units, configured to track a location of a passenger's head, a signal processor configured to detect the location of the passenger's ears and to control the orientation of the ultra-sound audio beam based on information provided by the passenger monitoring unit;

• further comprising a plurality of the acoustic sound emitters configured to transmit sound from a plurality of audio sources;
• a plurality of the ultrasonic speakers configured to transmit audio beams from a plurality of audio sources;
• a plurality of the passenger monitoring units;
• and wherein particular ones of the plurality of acoustic sound emitters and ultrasonic speakers, correspond to particular Passengers among multiple Passengers in the vehicle;
• further comprising at least one control unit, configured to control the time delays and volume differences between the acoustic sound emitters and ultrasonic speakers, the method comprising the steps of:
• tracking by at least one of the passenger monitoring units the current position of the head of the passenger;
• based on the tracking information, locating the ears and adjusting the ultrasound speakers by the signal processor to align with the ears of the passenger;
• propagating an ultrasound beam by the ultrasound speaker directed at the ears of the passenger.
