Abstract
An ultrasonic audio transducer system includes an ultrasonic speaker. The ultrasonic speaker may be an electrostatic emitter, a piezoelectric emitter (single crystal or stack), a piezoelectric film emitter, or any other emitter capable of emitting ultrasound. The ultrasonic speaker is configured to be coupled (via a wired or wireless connection) to an audio modulated ultrasonic carrier signal from an amplifier, wherein upon application of the audio modulated ultrasonic carrier signal, the ultrasonic speaker is configured to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air. Additionally, the ultrasonic speaker is implemented with an impedance matching element or optimized for matching the response within a user's ear canal.
