Abstract: Systems and methods for audio communication are disclosed. The system includes a plurality of transducer units and plurality of sensors adapted to be located in a plurality of sites/spaces to which service should be provided by the system. The plurality of transducer units are capable of emitting/directing and focusing ultra-sonic signals to respective coverage zones in the sites, such that localized (confined) sound field can be formed at selected spatial position in the coverage zones by utilizing sound from ultrasound technique. The sensors are associated with respective sensing volumes in the sites and are operable to obtain sensory data indicative of spatial arrangement of elements/object at the sensing volumes within the sites.

Abstract: Systems and methods for audio communication are disclosed. The system includes a plurality of transducer units and plurality of three dimensional sensor modules (TDSMs) adapted to be located in a plurality of sites/spaces to which service should be provided by the system. The plurality of transducer units are capable of emitting/directing and focusing ultra-sonic signals to respective coverage zones in the sites, such that localized (confined) sound field can be formed at selected spatial position in the coverage zones by utilizing sound from ultrasound technique.

Abstract: A system and method for producing virtual binaural audio space are disclosed. In some implementations, the method includes providing staged audio data indicative of an audio data piece and of a relative position of a virtual source from which the audio data piece should be perceived by a designated listener; determining a position (e.g. location and orientation) of a head of user, which designated to be the listener; and transmitting one or more ultrasound fields towards a one or more selected audio center points located in the vicinity of the user's head for producing, via sound from ultrasound effect, left and right audible sound fields carrying the audio data piece to the left and right ears of the user respectively.

Abstract: 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).

Abstract: A transducer system includes a panel having one or more piezo-electric enabled foils and an arrangement of electric contacts coupled to the panel. The one or more piezo-electric enabled foils and the arrangement of electric contacts define a plurality of transducers thereon. Each transducer is associated with a respective region of the panel and with at least two electric contacts that are coupled to at least two zones at that respective region of the panel. The electric contacts are adapted to provide an electric field in these at least two zones to cause different degrees of piezo-electric material deformation in these at least two zones and to thereby deform the respective region of the panel in a direction substantially perpendicular to a surface of the panel, and to thereby enable efficient conversion of electrical signals to mechanical vibrations (acoustic waves) and/or vice versa.
