See full text

Systems and methods of audio processing and control for improved audibility and performance in a parametric loudspeaker system. The parametric loudspeaker system includes a parametric loudspeaker providing a capacitive load, an output stage having a plurality of switches interconnected in a bridge configuration and connected to the capacitive load of the parametric loudspeaker, and a controller operative to generate a series of pulse width modulation (PWM) pulses, and to generate a plurality of control signals synchronized with the series of PWM pulses for switchingly controlling the plurality of switches in the bridge configuration, thereby driving the capacitive load of the parametric loudspeaker.
