Biaxial parametric speaker

Abstract

A biaxial parametric speaker having at least two different axes of sound propagation. The speaker includes a first parametric emitter including an ultrasonic emitter surface having a primary direction of propagation along a first orientation and a second parametric emitter including an ultrasonic emitter surface having a primary direction of propagation along a second orientation. The first parametric emitter is physically coupled to the second parametric emitter such that the first and second orientations do not coincide, thereby providing for relative angular displacement of the respective first and second orientations of propagation. Electronic contacts are attached to the respective first and second parametric emitters for coupling to a parametric signal source capable of generating parametric emissions from the respective emitters which decouple in air to generate audio output along each of the respective first and second orientations.
