Abstract
An ultrasonic emitter is provided, where at least one of an amplifier, driver circuit, and signal processing circuitry is integrated onto or into the ultrasonic emitter. The ultrasonic emitter may include a backing plate and an amplifier and/or associated processing integrated directly onto the backing plate for amplifying and matching an audio modulated ultrasonic carrier signal to the ultrasonic emitter. The emitter is configured to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air.
