Embodiment

[0035] The method for realizing multi-channel Bluetooth audio output described in the embodiment of the present invention is applied to a smart terminal, wherein the smart terminal may be a smart phone, a smart TV, a tablet computer or the like with a Bluetooth communication module and an audio playback function, The intelligent terminal establishes Bluetooth communication with multiple audio playback devices through the Bluetooth communication module, and the audio playback devices can be Bluetooth speakers. like figure 1 As shown, the method includes the following steps:

[0036] Step S1, determine the number N of channels that need to simultaneously output Bluetooth audio, and N is a natural number greater than 1;

[0037] Wherein, the method for determining the number N of channels that require simultaneous Bluetooth audio output includes: determining the number of audio playback devices that simultaneously establish Bluetooth connections with the smart terminal, and taki...

Abstract

The invention relates to the technical field of audio playing, aims to solve the problem that an existing intelligent terminal cannot simultaneously output multiple paths of Bluetooth audios, and provides a method and a device for realizing the output of the multiple paths of Bluetooth audios, which have the main technical conception: determining the number N of paths needing to simultaneously output the Bluetooth audios is determined, wherein N is a natural number greater than 1; acquiring audio data sent by the intelligent terminal, and processing the audio data to enable the bandwidth occupied by the audio data transmission to be less than 1 / N of the maximum bandwidth of the Bluetooth; copying the processed audio data into N parts, and correspondingly sending the copied N parts of audiodata to N audio playing devices in Bluetooth connection with the intelligent terminal; and enabling the audio playing device to synchronously play the received audio data. According to the invention,simultaneous output of multiple Bluetooth audios is realized, and the method is suitable for smart televisions.

Description

technical field [0001] The invention relates to the technical field of audio playback, in particular to a method and device for realizing multi-channel Bluetooth audio output. Background technique [0002] The current wirelessly connected Bluetooth speakers are widely used due to the advantages of no limitation of connecting wires and ease of use. However, in the prior art, although the smart terminal can connect to multiple Bluetooth devices at the same time, according to the standard classic Bluetooth protocol, due to the limitation of the Bluetooth bandwidth, it is only enough to output one Bluetooth audio. This makes the user's experience poor. For example, a home theater system centered on a smart TV in a user's home cannot simultaneously connect two Bluetooth speakers to output audio, which greatly reduces the sound effect of the home theater. Contents of the invention [0003] The present invention aims to solve the problem that existing intelligent terminals canno...
