Abstract

The invention discloses a method and device for determining sound delay duration of Bluetooth equipment and terminal equipment. The method for determining the sound delay duration of the Bluetooth equipment comprises the steps that when the sound delay of the Bluetooth equipment needs to be determined, playing a preset audio sequence through Bluetooth equipment; in the process of playing the audiosequence, collecting external sound through audio recording equipment in the terminal equipment, identifying the audio sequence from the collected external sound, and determining the time delay of audio playing of the Bluetooth equipment according to the time difference between the playing time and the collecting time of each audio signal in the audio sequence. Therefore, the time delay of playing the audio by the Bluetooth equipment is accurately determined, the terminal equipment can be conveniently controlled to play the video by adopting the Bluetooth equipment subsequently based on the determined time delay, and the audio and video synchronization of the terminal equipment is further realized.

Description

technical field [0001] The present disclosure relates to the field of terminal technology, and in particular to a method, device, terminal device and computer-readable storage medium for determining the sound delay time of a Bluetooth device. Background technique [0002] With the rapid development of terminal devices and Bluetooth devices, more and more Bluetooth devices can be connected to terminal devices. For example, there are more and more Bluetooth speakers and Bluetooth headsets that can be connected to mobile phones, laptops, smart TVs and other terminal devices. Many users These bluetooth devices will be used to play audio or video on the terminal, which brings great convenience to users' life. [0003] Currently, when a smart TV is connected to a bluetooth device through bluetooth, the smart TV usually adopts a way of accumulating a fixed delay to deal with different bluetooth devices. However, corresponding to different Bluetooth devices, the delays generated by...
