Abstract:
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.

Claim (Index 1):
In a parametric audio system, a method of processing an audio input signal, the parametric audio system including a modulator for modulating an ultrasonic carrier signal with the processed audio input signal to produce an ultrasonic drive signal for driving a parametric loudspeaker, the method comprising:\n monitoring a signal level corresponding to one of the audio input signal and the ultrasonic drive signal; generating a level number that corresponds to the monitored signal level; translating the level number to adjustment information for controlling an adjustment of one or more of a bass enhancement, an equalization, a compression, and a distortion of the audio input signal; and adjusting the one or more of the bass enhancement, the equalization, the compression, and the distortion of the audio input signal in accordance with the adjustment information.
