METHOD FOR SYNCHRONIZING AUDIO PLAYBACK OF PLURAL PLAYING DEVICES AND AUDIO PLAYBACK SYSTEM

摘要

A method for synchronizing audio playback includes following steps. Firstly, a first playing device is set as a master playing device. Then, a second operation status of a second playing device is switched to a first operation status of the first playing device. In response to an action command, a first time information of the first playing device is transmitted to the second playing device. By comparing the first time information with a second time information of the second playing device, the second playing device and the first playing device start the audio playback. The first time information and the second time information are continuously compared with each other, and a playback progress of the second playing device is correspondingly adjusted. Consequently, the audio playback of the second playing device and the first playing device are synchronized.
