Abstract:
Audio effects are played on ultrasonic (US) speakers mounted on a gimbal assembly. The audio effects channel demands an elevation, azimuth, and radial distance along which the audio effects are to be transmitted, and the gimbal assembly moves or a speaker is selected according to the audio effects channel. The demanded radial distance is established by altering the carrier frequency of the US sound.
