Abstract
This invention provides a parametric loudspeaker system, with a carrier frequency generator to produce a carrier frequency. A modulator receives an audio signal and modulates it onto the carrier frequency, producing a modulated signal. This modulation creates at least one sideband signal that is divergent from the carrier frequency by the frequency value of the audio signal. Additionally, the sideband signal is created such that its frequency value is lower than the frequency of the carrier.
