Abstract

See full text

A multi-channel audio playback system includes a front speaker, a wearable speaker, and a signal processor. The front speaker is configured to receive front sound field signals (FS). The wearable speaker is designed to allow a listener to hear environmental sounds and is configured to receive rear sound field signals (RS). The signal processor is configured to divide a multi-channel signal into a front sound field signal group (FSG) and a rear sound field signal group (RSG); mix FSG (RSG) and generate the FS (RS), wherein the number of the FS (RS) is equal to the number of the drivers of the front speaker (wearable speaker); and perform time delay adjustment on FS or RS, so that a difference between times for sound waves emitted by the front speaker and by the wearable speaker to respectively reach ears of the listener is less than a default value.
