Ultrasonic sound reproduction on eardrum

摘要

The invention is directed to systems, methods and computer program products for producing audible sound by directing ultrasonic signals from an ultrasonic transducer towards an eardrum. An exemplary method includes providing an earphone comprising an ultrasonic transducer, wherein the earphone is positioned close to an ear, wherein the ear includes an ear canal and an eardrum; producing, by the ultrasonic transducer, an ultrasonic signal; and transmitting, by the ultrasonic transducer, the ultrasonic signal, wherein the ultrasonic signal is directed into the ear canal towards the eardrum such that the eardrum receives the ultrasonic sound signal and initiates conversion of the ultrasonic signal into audible sound.
