Abstract:
A system of crosstalk cancelled zone creation in audio playback comprising: main transducers emitting stereo soundwaves of an audio playback; a local system comprising at least two or more close-proximity-transducers (CPTs), each is arranged proximal to one of left and right-side ear canals of a listener. Each of the CPTs comprises: a position tracking device for tracking the relative positions of the main transducers to the CPT and the other CPTs; a control unit for receiving the relative position data from the position tracking device and generating control signal according to the relative position data for the generation of crosstalk cancellation (XTC) soundwaves. Each of the CPTs is configured to generate XTC soundwaves corresponding to the stereo soundwaves arriving at the corresponding ear of the listener. The generated XTC soundwaves are synchronized with the audio playback and with respect to the relative positions.
