Embodiment 1

[0038] figure 2 It is a flowchart of an audio output method of a bluetooth headset according to an embodiment of the present invention, such as figure 2 Shown, a kind of audio output method of bluetooth earphone, described bluetooth earphone comprises main earphone and from earphone, and described method comprises:

[0039] In step S110, the main earphone receives the audio signal of the sound source, and separates the audio signal into a first channel audio signal and a second channel audio signal;

[0040] In an embodiment of the present invention, the audio source can come from a mobile phone, or from other audio playback devices with bluetooth functions.

[0041] In step S120, the second channel audio signal is sent to the earphone for audio output by using near field communication technology;

[0042] In step S130, the first channel audio signal is controlled to be buffered for a certain number of frames according to the pre-acquired buffer frame number for audio outp...

Embodiment 2

[0051] Figure 4 It is a flowchart of another Bluetooth headset audio output method according to an embodiment of the present invention, such as Figure 4 Shown, a kind of audio output method of bluetooth earphone, described bluetooth earphone comprises main earphone and from earphone, and described method comprises:

[0052] In step S110, the main earphone receives the audio signal of the sound source, and separates the audio signal into a first channel audio signal and a second channel audio signal;

[0053] In step S120, the second channel audio signal is sent to the earphone for audio output by using near field communication technology;

[0054] In step S130, according to the pre-acquired time when the audio signal of the second channel is sent to the slave earphone, the audio signal of the first channel is delayed for a certain period of time before audio output, so as to realize the audio signal of the first channel and the audio signal of the second channel. Two-chann...

Embodiment 3

[0059] Image 6 It is a schematic structural diagram of an audio output device of a bluetooth headset according to an embodiment of the present invention, such as Image 6 As shown, the device 300 includes:

[0060] an audio receiving unit 310, configured to receive an audio signal of a sound source;

[0061] an audio separation unit 320, configured to separate the audio signal into a first channel audio signal and a second channel audio signal;

[0062] The second channel audio sending unit 330 is configured to use near field communication technology to send the second channel audio signal to the earphone for audio output;

[0063] The first channel audio buffering unit 340 is configured to control the audio output of the first channel audio signal after buffering a certain number of frames according to the pre-acquired buffer frame number, wherein the pre-acquired buffer frame number is based on the second The audio signal of the channel is sent to the time acquisition of...

Abstract

The invention discloses an audio output method of a Bluetooth earphone, and the Bluetooth earphone. The Bluetooth earphone comprises a master earphone and a slave earphone, the method comprises the following steps: receiving audio signals of a sound source and separating the audio signals into a first sound channel audio signal and a second sound channel audio signal by the master earphone; sending the second sound channel audio signal to the slave earphone by using the near field communication technology to output audio; and controlling the first sound channel audio signal to cache a certain frame number according to a pre-obtained cache frame number and outputting the audio, wherein the pre-obtained cache frame number is obtained according to the time of sending the second sound channel audio signal to the slave earphone. The technical effect that the left and right Bluetooth earphones synchronously output the audio is realized, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of computer control, in particular to an audio output method and device for a bluetooth earphone and the bluetooth earphone. Background technique [0002] At present, Bluetooth wireless headsets mainly use Bluetooth communication technology to realize the connection and drive of the left earphone and the sound source, the left earphone realizes the separation of the sound channel, and uses the near-field communication technology to transmit the sound of the right channel to the right earphone, which solves the problem of traditional Bluetooth. The headphone connection is unstable and the sound is intermittent. Moreover, near-field communication technology has the advantages of low power consumption, human-friendliness, and high reliability. Therefore, the performance of wireless earphones using "Bluetooth + near-field communication technology" has been greatly improved. However, this near-field communication technolo...
