Multi-channel audio playback system

A multi-channel audio playback system comprising:

• a front one-box speaker comprising at least two drivers configured to receive at least two front sound field signals;
• a subwoofer speaker configured to receive a low frequency effect channel signal;
• a wearable speaker comprising at least two drivers, wherein the wearable speaker is designed to allow a listener to hear environmental sounds, and the wearable speaker is configured to receive at least two rear sound field signals;
• and
• a signal processor configured to:
• receive a multi-channel signal;
• divide the multi-channel signal into a front sound field signal group, a rear sound field signal group, and the low frequency effect channel signal;
• process the front sound field signal group to generate a plurality of front sound field signals, wherein the number of the front sound field signals is equal to the number of the drivers of the front one-box speaker;
• process the rear sound field signal group to generate a plurality of rear sound field signals, wherein the number of the rear sound field signals is equal to the number of the drivers of the wearable speaker;
• perform time delay adjustment on the front sound field signals or the rear sound field signals so that a difference between a time for a sound wave emitted by the front one-box speaker to reach ears of the listener and a time for a sound wave emitted by the wearable speaker to reach the ears of the listener is less than a default value;
• and
• output the front sound field signals to the front one-box speaker, output the low frequency effect channel signal to the subwoofer speaker, and output the rear sound field signals to the wearable speaker.
