Abstract:
1. An ultrasonic audio speaker, comprising: a backing plate; a flexible layer disposed adjacent the backing plate, the backing plate and the flexible layer each configured to be electrically coupled to a respective one of a pair of signal lines carrying an audio modulated ultrasonic carrier signal, wherein upon application of the audio modulated ultrasonic carrier signal, the flexible layer is configured to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air; and a visual indicator configured to provide visual feedback indicative of an orientation of the ultrasonic audio speaker relative to a position of an intended target of the audio modulated ultrasonic carrier signal, wherein the visual indicator is capable of being perceived by an individual only when the individual is positioned in the path of the audio modulated ultrasonic carrier signal.
