Abstract
The present invention relates to ear phone technology fields, and disclose a kind of connection method of true wireless headset, and steps are as follows: step 1, judge the major-minor situation of left earphone and right earphone, and the audio data of source device is transmitted to auricular appendage by main ear；The Bluetooth Synchronous data link of step 2, main ear and source device, main ear and auricular appendage is received and dispatched using 2EV-3 data packet；It, can not biphone the problem of speaking when solving call.
Description
Technical field
The present invention relates to ear phone technology field, specially a kind of connection method of true wireless headset.
Background technique
Develop by the technology of many years, wireless Bluetooth headsets rely on its portable, stable characteristic, gradually substitute wired ear
Machine becomes the preferred earphone of user.Traditional wireless Bluetooth headsets are often single earphone, also only unilateral call and broadcasting sound
It is happy；Nowadays, ear scheme has been graduallyd mature, it is desirable that two earphones are spoken simultaneously, for example, left ear plays left sound when playing music
Track data, auris dextra play right data.But in call, often only one earphone is spoken, and reason is that bluetooth conversation is
Based on synchronous data-link (SCO), requirement of real-time is very high, while both SCO link needs fixed time slot to transmit data,
The difficulty that forwarding between two connection data can become.
Summary of the invention
The present invention in order to solve problems in the prior art, provides a kind of connection method of true wireless headset, solves logical
It, can not biphone the problem of speaking when words.
In order to solve the above technical problems, the technical scheme is that a kind of connection method of true wireless headset, step is such as
Under:
Step 1, judges the major-minor situation of left earphone and right earphone, and the audio data of source device is transmitted to auricular appendage by main ear；
The Bluetooth Synchronous data link of step 2, main ear and source device, main ear and auricular appendage is received using 2EV-3 data packet
Hair.
Further, in step 1, cells electricity is sent to right earphone, right earphone comparative cell electricity by the left earphone
The height of amount, battery capacity is higher to be used as main earphone.
Further, the right earphone comparative cell electricity occurs in wireless headset booting.
Further, in step 2, the Bluetooth Synchronous data link of the main ear and source device, main ear and auricular appendage uses 2EV-
3 data packets carry out transmitting-receiving specific steps are as follows:
1) send audio: voice data is passed to bluetooth codec and is decoded and transmits voice data by source device
To main earphone, decoded data are put into main earphone PCM buffer area, are then converted data through main earphone DAC by main earphone DMA
Deposit is finally broadcast voice transfer to main earphone horn by main earpiece audio decoder into main earphone FIFO after device digital-to-analogue conversion
It releases；
2) after main earphone receives the voice data after bluetooth decoder is decoded, by voice before carrying out subsequent process
Data are transmitted to set of headphones, and decoded data are put into set of headphones PCM buffer area, then by set of headphones DMA by data through set of headphones
After DAC converter digital-to-analogue conversion deposit into set of headphones FIFO, finally by set of headphones audio decoder by voice transfer to auricular appendage
Machine loudspeaker play back；
3) receive audio: main ear microphone acquires data to main earpiece audio decoder and then is deposited into main earphone FIFO
In, and by main earphone ADC converter analog-to-digital conversion, main earphone PCM buffer area is then moved by main earphone DMA, is finally passed through
Bluetooth decoder coding, returns to source device.
Detailed description of the invention
Fig. 1 be a kind of main earphone synchronous data-link of wireless headset export using 2EV-3 data packet/receive audio
The flow chart of signal；
Fig. 2 is that a kind of set of headphones synchronous data-link of wireless headset carries out output audio signal using 2EV-3 data packet
Flow chart.
Specific embodiment
It is further to a kind of connection method technical solution of true wireless headset of the present invention below with reference to embodiment
It is described in detail.
A kind of connection method of true wireless headset as shown in Figs. 1-2, steps are as follows:
Step 1, judges the major-minor situation of left earphone and right earphone, and the audio data of source device is transmitted to auricular appendage by main ear；
The Bluetooth Synchronous data link of step 2, main ear and source device, main ear and auricular appendage is received using 2EV-3 data packet
Hair.
In step 1, cells electricity is sent to right earphone, the height of right earphone comparative cell electricity by the left earphone
Low, battery capacity is higher to be used as main earphone.
The right earphone comparative cell electricity occurs in wireless headset booting.
In step 2, the Bluetooth Synchronous data link of the main ear and source device, main ear and auricular appendage uses 2EV-3 data packet
Carry out transmitting-receiving specific steps are as follows:
1) send audio: voice data 100 is passed to bluetooth codec 101 and is decoded and by voice number by source device
Main earphone is passed to according to 100, and decoded data are put into main earphone PCM buffer area 102, then data are passed through by main earphone DMA
Deposit, finally will by main earpiece audio decoder 106 into main earphone FIFO105 after main earphone DAC103 converter digital-to-analogue conversion
Voice transfer is played back to main earphone horn 107；
2) after main earphone receives the voice data 100 after bluetooth decoder 101 is decoded, before carrying out subsequent process
Voice data 100 is transmitted to set of headphones, decoded data are put into set of headphones PCM buffer area 202, then will by set of headphones DMA
Data are stored in after set of headphones DAC203 converter digital-to-analogue conversion into set of headphones FIFO 204, finally by set of headphones audio decoder
Device 205 plays back voice transfer to set of headphones loudspeaker 206；
3) receive audio: main ear microphone 108 acquires data to main earpiece audio decoder 106 and then is deposited into main ear
In machine FIFO 105, and by main earphone ADC104 converter analog-to-digital conversion, main earphone PCM is then moved by main earphone DMA and is delayed
Area 102 is deposited, is finally encoded by bluetooth decoder 101, returns to source device.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
