System and method for creating crosstalk cancellation zone in audio reproduction

摘要

A system for creating crosstalk cancel zones in audio playback, with a main transducer that emits stereo sound for audio playback; at least two proximity transducers (CPTs, each placed close to either the listener's left or right ear canal. A local system with) and a system with. Each of the CPTs has a position tracking device for tracking the relative position of the main transducer with respect to the CPT and other CPTs; and receives relative position data from the position tracking device to generate crosstalk cancellation (XTC) sound waves. It is equipped with a control unit for generating a control signal according to the relative position data for. Each of the CPTs is configured to generate an XTC sound wave corresponding to the stereo sound wave reaching the listener's corresponding ear. The XTC sound waves generated are synchronized with respect to the audio reproduction and the relative position. [Selection diagram] Fig. 4
