Abstract: An audio synchronization method for Bluetooth speakers is disclosed. The Bluetooth speakers comprise a first Bluetooth speaker and a second Bluetooth speaker transmitting digital audio packets by Bluetooth communication. The method comprises steps of: fetching the sample counts of the first Bluetooth speaker and the second Bluetooth speaker at the first timing; and adjusting the sample rate of the second Bluetooth speaker according to the sample counts of the first Bluetooth speaker and the second Bluetooth speaker. By using the method of the present invention, the sample counts are checked periodically to keep the Bluetooth speakers audio synchronized.
