Currently, playing the audio data in electronic equipment using wireless audio playback equipment, wired earphone institute can be reduced Bring is inconvenient, and still, inventor has found under study for action, when playing audio using wireless audio playback equipment, due to Audio is by wireless network transmissions such as bluetooths, and will cause audio, there are time delays, especially when playing video, video pictures Broadcasting be by electronic equipment parsing after play back, and the corresponding audio of video need electronic equipment by coding etc. one It is sent to wireless audio playback equipment after sequence of maneuvers and plays, during transmission, can there is delay, for example, delay Thus about 100-300ms will cause the asynchronous of picture and audio, for example, in game picture, the game neutron bomb of gunbattle Sound delay greatly reduces user experience.

Inventor find under study for action one that leads to above-mentioned delay the reason is that, since electronic equipment and wireless audio play It is transmitted between equipment by Bluetooth transmission protocol, under the agreement, for the integrality for guaranteeing data, is sent in data by transmitting terminal When receiving end, it can feed back one if receiving end receives the data and be used to indicate the mark for having received the data, for example, being One parametric variable.It can feed back one if receiving end does not receive the data and be used to indicate the mark for not receiving the data, Then transmitting terminal can retransmit the primary data, the as retransmission mechanism under Bluetooth transmission protocol.Although and the mechanism can guarantee The data of transmitting terminal are more completely sent to receiving end, avoid receiving end missing data, and still, repetition sends the data, can be somebody's turn to do The delay of data receiving end receives, while also resulting in the data sent in sequence after the data and being also delayed by reception.And such as Fruit is when wireless audio playback equipment plays audio data transmitted by electronic equipment, using above-mentioned retransmission mechanism, just It will lead to the delay of audio signal, and cause picture asynchronous with audio, reduce user experience.

Therefore, to solve the above-mentioned problems, referring to Fig. 2, the embodiment of the present application provides a kind of data transmission method, answer For electronic equipment, specifically, this method comprises: S201 to S203.

S201: when electronic equipment connects wireless audio playback equipment, detect whether the electronic equipment receives audio The playing request of data.

When the Bluetooth function of electronic equipment is opened, electronic equipment can set the bluetooth within the scope of certain distance around Standby scanning, specifically, after receiving scan command by the Bluetooth chip of electronic equipment or other bottom-layer network modules, according to pre- If scan channel sequence be scanned, such as first scan 1,7,13 channel of common channels, then scan other non-common channels, by This obtains the mark of all bluetooth equipments in present scope, and is shown in the bluetooth list interface of electronic equipment.

It had been connected and the preferable bluetooth of signal strength is set if existed in the mark of the bluetooth equipment scanned Standby, electronic equipment can be connect with the bluetooth equipment automatically, then user can also select a bluetooth to set in bluetooth list interface It is standby to be attached.

When electronic equipment is connect with external bluetooth equipment, then the system of electronic equipment, which can be crossed, goes to a state value, The state value indicates that electronic equipment has currently connected bluetooth equipment.To, electronic equipment is able to detect that bluetooth equipment, To get the device identification of bluetooth equipment.

After the device identification for getting connected bluetooth equipment, connected bluetooth is determined according to the device identification Whether equipment is wireless audio playback equipment, and specifically, which may include title or brand of equipment etc., example Such as, it can determine whether the equipment is the wireless audio playback equipment such as earphone or sound equipment according to the device identification, so as to true It is fixed whether to be connected with wireless audio playback equipment.Alternatively, it is also possible to be the device identification for determining connected bluetooth equipment, so Afterwards, the corresponding equipment kind of current connected device identification is obtained in the corresponding relationship of preset device identification and device category Whether class is wireless audio playback equipment so as to the type of the current connected equipment of determination.

When determining that electronic equipment connects wireless audio playback equipment, that is to say, that wireless in electronic equipment connection After audio-frequence player device, whether detection electronic equipment receives playing request, which is for requesting to play audio The request of data.

Specifically, playing request can be prompting message, be also possible to voice playing request.Wherein, prompting message includes The letter that call-prompting information, short message prompting message and clock alarming information etc. are used to remind the certain events of user triggered Breath.For example, call-prompting information is for reminding user currently to have incoming call.

As another embodiment, sounding request can be during electronic equipment sounding, play voice every time Request.Then sounding request can be the request of audio sounding, be also possible to the request of video sounding or call sounding request.

Specifically, multiple audio playing softwares are installed, then the software can be music APP, view in electronic equipment Frequency plays APP or recording APP etc..For example, video playing interface is provided with video playing key, by pressing to the video playing The detection of the touch-control of key, can determine whether electronic equipment currently receives the playing request of audio data, for example, user chooses Video clicks the broadcast button of the broadcast interface into the broadcast interface of video, and application program passes through to user's touch control operation It monitors, be able to detect that user currently clicked is what kind of video, and specifically, broadcast button is provided with default category Property, detect the attribute of the acquired corresponding broadcast button of touch control operation, it will be able to determine the view to be played that user is chosen Frequently, and then playing request and the corresponding audio of the playing request are got.

S202: the upper limit number that the data between the electronic equipment and the wireless audio playback equipment retransmit is reduced.

If receiving playing request, then it represents that current electronic device is in the state for preparing playing audio-fequency data, then obtains The upper limit number for taking the data between electronic equipment and wireless audio playback equipment to retransmit, specifically, the upper limit time that data retransmit Used Bluetooth protocol is related between several and electronic equipment and wireless audio playback equipment, and the corresponding data of the agreement retransmit Upper limit number be generally the numerical value of the corresponding fixation of the agreement, for example, the upper limit number that data retransmit is 3.

, can be by audio data coding at multiple packets of audio data in addition, when transmitting audio data, and multiple audios Data packet sends sequence according to certain data and is sent to wireless audio playback equipment, specifically, detects the electronic equipment hair The target audio data packet to the wireless audio playback equipment is sent whether to lose, wherein target audio data packet sets for electronics One in multiple data packets corresponding to the standby audio data to be played.Then mesh is successfully received in wireless audio playback equipment The state value of a successful reception can be fed back after mark packets of audio data to electronic equipment, then if being within a certain period of time reception To the state value, then electronic equipment determines that the wireless audio playback equipment is unsuccessfully received target audio data packet, i.e., described Electronic equipment is sent to the target audio data-bag lost of the wireless audio playback equipment, then, judges the audio data Wrap the upper limit number whether corresponding the number of transmissions is less than data re-transmission.Wherein, the number of transmissions is that this electronic equipment sends sound During frequency evidence to wireless audio playback equipment, the number of transmitted target audio data packet specifically sends target The number of packets of audio data can be recorded, and with the change of transmission times, perhaps the number of the target audio data packet is repaired Change, for example, one parameter value s of setting, parameter value s is used to record the number for sending target audio data packet, i.e., if sent 1 time, then s=1.After target packet is sent successfully, s can be reset.Assuming that a parameter value d, the d are for indicating data The upper limit number of re-transmission, for example, the upper limit number that data retransmit is 3, then parameter value d is 3.By s compared with d, the two is judged Between size.

Then if determining the corresponding the number of transmissions of packets of audio data less than the upper limit number that data retransmit, again by institute It states target audio data packet and is sent to the wireless audio playback equipment；If more than or be equal to, stop the target audio data The transmission of packet sends sequence according to preset data and sends audio data after the target audio data packet to the wireless sound Frequency playback equipment.

Specifically, it is assumed that it includes data packet 1, data packet 2, data packet 3, data packet 4, data packet 5 in sequence that data, which are sent, Etc..Then by taking target audio data packet is data packet 1 as an example, after data packet 1 sends failure, if the hair of the data packet 1 It send number to be greater than the upper limit number that data retransmit, then abandons data packet 1, and continue to send data packet 2 and subsequent data packet.

As it can be seen that the upper limit number that very high data retransmit can guarantee the integrality that data are sent, avoid losing some data of book, And if reducing the upper limit number that data retransmit, although some data can be lost, the acquisition of the data after the data Delay can reduce, if for example, above-mentioned data packet 1 is just immediately given up after sending primary failure and sends data packet 2, then Although being lost data packet 1, it can be quickly obtained data packet 2, without sending a data packet 1 until reattempting.

Therefore, in the embodiment of the present application, in order to reduce the delay of audio broadcasting, the electronic equipment and the nothing are reduced The upper limit number that data between line audio-frequence player device retransmit.As an implementation, by the electronic equipment with it is described The upper limit number that data between wireless audio playback equipment retransmit is revised as default value, and the default value is 1 or 0, tool Body, if the upper limit number that the data retransmit is greater than 1, the upper limit number that data retransmit can be revised as 1 or 0, if The upper limit number that the data retransmit is equal to 1, then the upper limit number that data retransmit can be revised as 0.

S203: the audio data is sent to described wireless by the upper limit number retransmitted according to the data after reduction Audio-frequence player device indicates the wireless audio playback equipment playing audio data.

Specifically, it detects the electronic equipment and is sent to the packets of audio data of the wireless audio playback equipment and whether lose It loses；If so, judging the upper limit number that the data whether corresponding the number of transmissions of the packets of audio data is less than after reducing retransmit；If It is less than, the packets of audio data is sent to the wireless audio playback equipment again；If more than or be equal to, stop the audio The transmission of data packet sends sequence according to preset data and sends audio data after the packets of audio data to the wireless sound Frequency playback equipment.Wherein, multiple numbers that the audio data that preset data sends that sequence is got by electronic equipment is split to form According to the transmission sequence of packet, which can divide according to the time shaft that audio plays.

In addition, it is necessary to which explanation, when electronic equipment is sent to wireless audio playback equipment non-audio data, is used Data retransmit upper limit number can not have to reduce, and use default upper limit number.

Therefore, the upper limit number retransmitted by above-mentioned reduction data, can be to avoid by some data in audio data It is excessive to wrap the number retransmitted, and the time for causing entire audio data to be sent to wireless audio playback equipment is not delayed.
