AI Technical Summary

Problems solved by technology

Using this method will cause the following problems: Since the transmission time between the two devices is uncertain, especially if strong interference is encountered, it may be retransmitted multiple times. If the time point of simultaneous playback is set too small, Then the interactive data packet will start playing before it is received, resulting in asynchronous
If the time point is set too long, a lot of audio data has been cached in the final playback, and the delay in starting playback will become very large

Abstract

The main purpose of the embodiment of the invention is to provide an audio playing method of a Bluetooth TWS device, the Bluetooth TWS device comprises a master device and a slave device, and the method comprises the steps that the master device and the slave device receive a first audio packet sent by a sound source device at the same time, and record a corresponding Bluetooth clock t; calculating the time overhead d required from the time when the first audio packet is received to the time when playing is started; and the master device and the slave device start playing at the time t + d ofthe Bluetooth clock at the same time. Correspondingly, the embodiment of the invention further provides an audio playing device of the Bluetooth TWS equipment. By adopting the technical scheme provided by the embodiment of the invention, the initial delay of playing can be effectively reduced.

Description

technical field [0001] The present application relates to the field of multimedia technologies, and in particular, to a method and device for audio playback of a Bluetooth TWS device. Background technique [0002] With the advancement of technology, in the field of multimedia technology, wireless audio devices, such as wireless earphones, are more and more popular. The most commonly used wireless earphones are Bluetooth earphones. At present, two earphones that are completely independent are generally called TWS (True Wireless Stereo, true wireless stereo) earphones, that is, there is no need for a wired connection between the two earphones. Each earphone is an independent wireless earphone, which technically means that the mobile phone is connected to the main earphone, and then the main earphone is wirelessly connected to the slave earphone through Bluetooth, so as to realize the true wireless separation of the left and right channels of Bluetooth. When the slave headphon...
