摘要：
Described herein are various technologies pertaining to parametric speakers. A parametric speaker is driven based upon a determined location of an ear of a listener. The parametric speaker outputs an ultrasonic beam that comprises several modulated signals, the modulated signals being carrier signals modulated by an audio signal. The parametric speaker is driven such that a main lobe of the ultrasonic beam has a focal point between the ear of the listener and the parametric speaker.
