Zusammenfassung: | A system and method for providing sound-data indicative of an audible sound to be produced and location-data indicative of a designated spatial location at which the audible sound is to be produced; and utilizing the sound-data and determining frequency content of ultrasound beams to be transmitted by an acoustic transducer system including an arrangement of ultrasound transducer elements for generating said audible sound. The ultrasound beams include primary audio modulated ultrasound beam(s), whose frequency contents includes ultrasonic frequency components selected to produce the audible sound after undergoing non-linear interaction in a non-linear medium, and additional ultrasound beam(s) each including ultrasonic frequency component(s). The location-data is utilized for determining focal points for the ultrasound beams respectively such that focusing the ultrasound beams on the focal points enables generation of a localized sound field with the audible sound in the vicinity of the designated spatial location. |
