Abstract
An audio-visual reproduction apparatus is provided. The audio-visual reproduction apparatus includes a visual display screen and an ultrasonic transducer array having two or more transducer elements arranged around the periphery of the screen for generating an ultrasonic beam modulated with an audio-frequency signal. Non-linear effects in the air demodulate the audio-signal to generate an audio beam propagating perpendicular to the screen. Such an integration of audio and vision may make the user feel as if the sound is being generated from the display screen when he or she is watching it, and also may project the sound towards a target user and seldom, or never, disturb unrelated persons. The ultrasonic transducer array may be made up of independent transducer elements, or may comprise two or more sub-arrays of transducer elements.
