Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

Generally, in the application scenario of TWS, in order to achieve the stereo effect, the audio data played by the left ear headphone device and the right ear headphone device also match each other under the premise of certain differences. For example, suppose the audio data packets to be played by the left ear headphone device are (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ ), and the audio data packets to be played by the right ear headphone device are ( YS ₂₁ , YS ₂₂ , YS ₂₃ , YS ₂₄ ). The audio data packets YS ₁₁ and YS ₂₁ , YS ₁₂ and YS ₂₂ , YS ₁₃ and YS ₂₃ , and YS ₁₄ and YS ₂₄ are different but correspond to each other.

If the left ear headphone device or the right ear headphone device has packet loss when receiving audio data packets, for example, the audio data packets received by the left ear headphone device are (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ ), The audio data packets received by the headphone device are (YS ₂₁ , YS ₂₃ , YS ₂₄ ). The audio data packet YS ₂₂ is missing from the right earphone device; then the audio playback of the left earphone device and the right earphone device cannot be matched.

In view of the problem of packet loss when the left-ear headphone device or the right-ear headphone device receives audio data packets, a feasible solution is to send the audio data source device (the sending device of the audio data packet, for example, connect the left-ear headphone device with the The mobile phone of the right ear headphone device) sends a data packet re-send request, requesting the audio data source device to re-send the missing audio data packets.

However, sending a reissue request to the audio data source device, and then receiving the reissued audio data packets from the audio data source device, this process will not only affect the audio data source device to send audio data packets to the left ear headphone device or the right ear headphone normally. The data interaction process of the device, and the delay caused by the sending of the reissue request and the reception of the reissued audio data packets, may cause the reissued audio data packets to fail to catch up with the normal audio data packet playback process.

In response to the above problem, in an embodiment of the present application, instead of requesting reissue of audio data packets from the audio data source device, the left ear headphone device and the right ear headphone device mutually confirm whether the other party has audio data packets missing, and send their own Among the audio data packets received by the device, the audio data packets corresponding to the audio data packets missing from the counterpart device are sent to the counterpart device. For example, the audio data packets received by the left ear headphone device are (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ ), and the audio data packets received by the right ear headphone device are ( YS ₂₁ , YS ₂₃ , YS ₂₄ ). The audio data package YS ₂₂ is missing from the right ear headphone device. The left ear headphone device sends the audio data packet YS ₁₂ to the right ear headphone device. Then, the audio data packets played by the left ear headphone device are (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ ), and the audio data packets played by the right ear headphone device are (YS ₂₁ , YS ₁₂ , YS ₂₃ , YS ₂₄ ). Although the left ear headphone device plays the audio data packet YS ₁₂ synchronously with the right ear headphone device, the stereo effect of the left ear headphone device playing the audio data packet YS ₁₂ and the right ear headphone device playing the audio data packet YS ₂₂ cannot be realized. Play audio data packets (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ ) on the left ear headphone device, and play audio data packets (YS ₂₁ , YS ₂₃ , YS ₂₄ ) on the right ear headphone device. The matching degree of left and right ear audio playback is greatly improved, and the user experience is also greatly enhanced.

Further, in the embodiment of the present application, a data receiving period is set according to a preset period (for example, every 2 seconds is divided into a data receiving period; for example, every N voice periods are set as a data receiving period), After a data receiving cycle ends, on one headphone device A1, confirm the audio data packets missing from another headphone device B1 in the just ended data receiving cycle, so that the headphone device A1 sends the headphone device to the headphone device B1. The audio data packet corresponding to the audio data packet missing from device B1.

Specifically, an embodiment of the present application proposes a data transmission method. The method is executed by one of the two earphone devices that are paired with each other, and thereby determines the missing audio data packet of the other earphone device, so as to perform the audio data packet transfer from one earphone device to the other earphone device.

For example, among the paired left-ear headphone device and right-ear headphone device, the left-ear headphone device executes the data transmission method proposed in an embodiment of the present application, thereby determining the audio data packets missing from the right-ear headphone device, and performing the data transmission from the left-ear headphone device to the left-ear headphone device. The ear headphone device is sent in addition to the audio data packets of the right ear headphone device. Alternatively, among the paired left-ear headphone device and right-ear headphone device, the right-ear headphone device executes the data transmission method proposed in an embodiment of the present application, thereby determining the audio data packets missing from the left-ear headphone device, and performing the data transmission from the right-ear headphone device. Supplementary transmission of audio data packets from the ear headphone device to the left ear headphone device.

Specifically, FIG. 1 shows a flowchart of a data transmission method according to an embodiment of the present application. The earphone device A1 and the earphone device B1 are earphone devices (a left ear earphone device and a right ear earphone device) that are paired with each other. As shown in Figure 1, after the data receiving period Q11 ends, the headphone device A1 performs the following process:

Step 110, receive the index parameter S1 from the earphone device B1, wherein the index parameter S1 is used to describe the receiving state of the audio data packet of the earphone device B1 in the data receiving period Q11;

Step 112: Send to the earphone device B1, among the audio data packets received by the earphone device A1 in the data receiving period Q11, the audio data packets corresponding to the audio data packets missing from the earphone device B1.

Based on the process shown in FIG. 1 , an embodiment of the present application further proposes a data transmission apparatus. The device is built into one of two headphone devices paired with each other. FIG. 2 is a structural diagram of a headphone data transmission apparatus according to an embodiment of the present application. The earphone device A1 and the earphone device B1 are paired earphone devices (the left ear earphone device and the right ear earphone device), and the device is built in the earphone device A1, as shown in Figure 2, the device includes:

The data receiving module 210 is used for receiving the index parameter S1 from the earphone device B1, wherein the index parameter S1 is used to describe the audio data packet receiving state of the earphone device B1 in the data receiving period Q11;

The data packet missing determination module 220 is used for confirming the audio data packets missing from the headphone device B1 in the data receiving period Q11 according to the index parameter S1;

The data packet sending module 230 is used for sending to the headphone device B1, among the audio data packets received by the headphone device A1 in the data receiving period Q11, the audio data packets corresponding to the audio data packets missing from the headphone device B1.

Further, in order to realize step 110 in the embodiment shown in FIG. 1 , an embodiment of the present application further proposes a data transmission method. Specifically, FIG. 3 is a flowchart of a data transmission method according to an embodiment of the present application. As shown in Figure 3, the headset device B1 needs to perform the following process:

Step 320, according to the audio data packet received by the headphone device B1 in the data receiving period Q11, generate an index parameter S1;

Step 321: Send the index parameter S1 to the earphone device A1.

Based on the process shown in FIG. 3 , an embodiment of the present application further proposes a data transmission apparatus. FIG. 4 is a structural diagram of a headphone data transmission apparatus according to an embodiment of the present application. The device is built in the headset device B1, as shown in Figure 4, the device includes:

An index parameter generation module 410, which is used to generate an index parameter S1 according to the audio data packet received by the headphone device B1 in the data receiving period Q11;

The index parameter sending module 420 is used for sending the index parameter S1 to the earphone device A1.

According to the embodiments shown in FIG. 1 and FIG. 2 , the audio data packets missing from the earphone device B1 can be confirmed on the earphone device A1, and the audio data packets are reissued by the earphone device A1 to the earphone device B1. According to the method of an embodiment of the present application, it is not only possible to effectively confirm that the data packets that exist when the headphone device receives the audio data packets is missing, but also, for the missing audio data packets, the data packets can be reissued between the matching headphone devices. , thereby greatly improving the matching of the audio data packets played by the two matching headphone devices, and improving the user experience.

Further, in practical application scenarios, those skilled in the art can implement the index parameter for describing the receiving state of the audio data packet in the data receiving period of the headphone device by adopting various solutions.

For example, in an embodiment of the present application, a sequence identifier is configured for an audio data packet. In the audio data packets received by the left ear headphone device and the right ear headphone device, the audio data packets corresponding to each other have the same sequence identifier. For example, the audio data packet is that YS ₁₁ and YS ₂₁ have the same sequence ID, YS ₁₂ and YS ₂₂ have the same sequence ID, YS ₁₃ and YS ₂₃ have the same sequence ID, and YS ₁₄ and YS ₂₄ have the same sequence ID.

In the same data receiving cycle, the sequence identifiers of each audio data packet received by a single earphone device are different, and the index parameter includes the sequence identifiers of all audio data packets received by a single earphone device in a data receiving cycle. In this way, it is only necessary to compare the sequence identifier of the audio data packet received by the left ear headphone device and the sequence identifier of the audio data packet received by the right ear headphone device, and then it can be confirmed that the left ear headphone device or the right ear headphone device is missing. The sequence identifier of the audio packet.

For example, suppose that in the data receiving period Q21, the audio data packets sent to the left ear headphone device are (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ , YS ₁₅ ), and the audio data packets sent to the right ear headphone device are ( YS ₂₁ , YS ₂₂ , YS ₂₃ , YS ₂₄ , YS ₂₅ ). Then, if the sequence identifiers of the audio data packets (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ , YS ₁₅ ) are A1, A2, A3, A4, and A5, respectively, the audio data packets (YS ₂₁ , YS ₂₂ , YS ₂₃ , The sequence identifiers of YS ₂₄ and YS ₂₅ ) are also A1, A2, A3, A4, and A5, respectively.

It is assumed that the current earphone device (left ear earphone device) receives audio data packets (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ , YS ₁₅ ) in the data receiving period Q21 . The first earphone device (the right earphone device) receives the audio data packets (YS ₂₁ , YS ₂₃ , YS ₂₄ , YS ₂₅ ) in the data receiving period Q12.

After the data receiving period Q21 ends, the first earphone device sends the first index parameters (A1, A3, A4, A5) to the current earphone device. After the current headphone device receives the first index parameters (A1, A3, A4, A5), according to the first index parameters, compare the sequence identifiers (A1, A1, A2, A3, A4, A5), thereby confirming that the first earphone device is missing the audio data packet with the sequence identifier A2 in the first data receiving cycle. The current earphone device sends the audio data packet YS ₁₂ with the sequence identifier A2 received by itself in the data receiving period Q21 to the first earphone device.

For another example, in one embodiment, one data reception period includes multiple data receptions (for example, according to the communication protocol, 20 data reception operations will be implemented in 1 second, and 2 seconds is set as a data reception period, then, A data receiving cycle includes 40 data receiving times), and each time the data receiving is successfully executed, the headset device will receive an audio data packet.

The index parameter is a string of binary codes (eg, a data parameter in UINT32 format). Each bit in the index parameter corresponds to one data reception in the data reception cycle, and the value of each bit in the index parameter represents its corresponding data reception status. 0 means that no audio data packets have been received during this data reception.

For example, assuming that in the data receiving period Q21, the audio data packets sent to the left ear headphone device are (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ , YS ₁₅ ), and the current headphone device (left ear headphone device) is receiving data Cycle Q21 receives audio data packets (YS ₁₁ , YS ₁₂ , YS ₁₃ , YS ₁₄ , YS ₁₅ ); the audio data packets sent to the right ear headphone device are ( YS ₂₁ , YS ₂₂ , YS ₂₃ , YS ₂₄ , YS ₂₅ ) ), the first earphone device (the right earphone device) receives the audio data packets (YS ₂₁ , YS ₂₃ , YS ₂₄ , YS ₂₅ ) in the data receiving period Q12 .

After the data receiving period Q21 ends, the first earphone device sends the first index parameter 10111 to the current earphone device, wherein the index parameter 10111 represents that no audio data packet is received during the second data reception in the data receiving period Q21. After the current earphone device receives the first index parameter 10111, according to the first index parameter, it is confirmed that the first earphone device is missing the audio data packet of the second data reception in the first data reception cycle. The current earphone device sends the audio data packet YS ₁₂ received by itself in the data receiving period Q21 and received for the second time to the first earphone device.

Further, in an embodiment of the present application, the flow of the data transmission method shown in FIG. 1 and FIG. 2 is performed synchronously by two paired earphone devices, and the two earphone devices mutually determine the audio data packets missing from the other device to perform two Complementary sending of audio packets between headsets.

FIG. 5 is a sequence diagram of a data transmission method according to an embodiment of the present application.

As shown in FIG. 5 , the left earphone device A2 and the right earphone device B2 are earphone devices that are paired with each other. After the data receiving cycle Q31 ends:

Step 510, the left ear headphone device A2 generates an index parameter S21 according to the audio data packet received in the data receiving period Q31;

Step 511, the left ear headphone device A2 sends the index parameter S21 to the right ear headphone device B2.

At the same time, after the data receiving cycle Q31 ends:

Step 520, the right ear headphone device B2 generates an index parameter S22 according to the audio data packet received in the data receiving period Q31;

Step 521, the right ear headphone device B2 sends the index parameter S22 to the left ear headphone device A2.

further:

Step 512, the left ear headphone device A2 receives the index parameter S22;

Step 513, according to the index parameter S22, the left ear headphone device A2 confirms the audio data packets missing from the right ear headphone device B2 in the data receiving period Q31;

Step 514, the left ear headphone device A2 sends to the right ear headphone device B2, and the audio data packets received by the left ear headphone device A2 in the data receiving period Q31 correspond to the audio data packets missing from the right ear headphone device B2 audio packets.

at the same time:

Step 522, the right ear headphone device B2 receives the index parameter S21;

Step 523, according to the index parameter S21, the right ear headphone device B2 confirms the audio data packets missing from the left ear headphone device A2 in the data receiving period Q31;

In step 524, the right-ear headphone device B2 sends to the left-ear headphone device A2, and the audio data packets received by the right-ear headphone device B2 in the data receiving period Q31 correspond to the audio data packets missing from the left-ear headphone device A2. audio packets.

FIG. 6 is a flowchart of a data transmission method according to an embodiment of the present application. Two paired headphone devices both perform the following process as shown in Figure 6:

Step 610, after one data reception ends, check whether an audio data packet is received;

Step 611, refresh the index parameter, and determine the value of the corresponding bit in the index parameter according to the check result in step 610;

Step 620, judging whether the current round of data reception cycle ends, for example, setting every N data reception as a data reception cycle, and judging whether the data reception just ended is an integer multiple of N data reception;

If the determination in step 620 is no, return to step 610;

If the determination in step 620 is yes, execute step 630;

Step 630, sending the index parameter to another headset device;

Step 640, receiving an index parameter from another headset device;

Step 650, according to the index parameter from another earphone device, determine the audio data packet missing from another earphone device;

Step 660: Send the audio data packet corresponding to the audio data missing from the other earphone device to the other earphone device.

Further, in the application scenario of TWS, after the headphone device receives the audio data packet, the audio data packet will be sent by the communication module of the headphone device to the audio module for decoding and playback. In an embodiment of the present application, after a data receiving period ends, when the two earphone devices complete the retransmission of audio data packets between each other, the audio data packets of the data communication period are sent to the audio module for decoding and playback.

Further, in the application scenario of TWS, due to the existence of problems such as data transmission delay and audio data packet decoding stuck, when the left and right earphone devices play their respective audio data packets, the playback progress of the left and right earphone devices will appear inconsistent. In view of this situation, in an embodiment of the present application, one headphone device sends its own playback progress to another headphone device, and the headphone device that receives the playback progress of the other device adjusts its own playback speed, to synchronize the playback progress of the two headset devices.

Specifically, in an embodiment of the present application, a sequence identifier is configured for the audio data packet for the audio data packet, and among the audio data packets received by the left ear headphone device and the right ear headphone device, the audio data packets corresponding to each other have the same sequence identifier. Between two playback progress synchronizations, the sequence identifiers of each audio data packet received by a single headphone device are different.

FIG. 7 is a sequence diagram of a data transmission method according to an embodiment of the present application. Two paired headphone devices (headphone device A3 and headphone device B3) execute the following process as shown in Figure 4:

Step 710, the earphone device A3 sends the first clock signal and the first data packet sequence identifier to the earphone device B3, wherein the first clock signal is the current clock signal of the earphone device A3, and the first data packet sequence identifier is that the earphone device A3 is currently The sequence identifier of the audio data packet being played;

Step 720, the earphone device B3 receives the first clock signal and the first data packet sequence identifier;

Step 721, the headphone device B3 determines the playback speed of the audio data packet played by the current headphone device according to the first clock signal, the second clock signal, the first data packet sequence identifier and the second data packet sequence identifier, wherein the second clock signal is the headphone. The current clock signal of the device B3, and the second data packet sequence identifier is the sequence identifier of the audio data packet currently being played by the headphone device B3.

Specifically, in an actual application scenario, each execution device in the embodiments shown in FIG. 1 , FIG. 3 , FIG. 5 , FIG. 6 , and FIG. 7 can be matched as required.

For example, in an application scenario, the left-ear headphone device sends index parameters, clock signals and data packet sequence identifiers to the right-ear headphone device, and the right-ear headphone device re-sends audio data packets to the left-ear headphone device and adjusts its own playback speed.

For another example, in an application scenario, the right ear headphone device sends an index parameter, a clock signal, and a data packet sequence identifier to the left ear headphone device, and the left ear headphone device re-sends audio data packets to the right ear headphone device and adjusts its own playback speed. .

For another example, in an application scenario, the right ear headphone device sends the index parameter, the clock signal and the data packet sequence identifier to the left ear headphone device, the left ear headphone device sends the index parameter to the right ear headphone device, and the left and right earphone devices complement each other. Audio data packets, the left ear headphone device adjusts its own playback speed.

For another example, in an application scenario, the left ear headphone device sends the index parameter, the clock signal and the data packet sequence identifier to the right ear headphone device, the right ear headphone device sends the index parameter to the left ear headphone device, and the left and right earphone devices complement each other. Audio data packets, the right ear headphone device adjusts its own playback speed.

Further, in practical application scenarios, those skilled in the art can implement step 721 by adopting various different playback speed adjustment strategies. For example, when the first data packet sequence identifier is the sequence identifier before the second data packet sequence identifier, it means that the current playback progress of the headphone device A3 is slower than that of the headphone device B3, and the headphone device B3 needs to slow down its own playback speed; When the packet sequence identifier is the sequence identifier after the second data packet sequence identifier, it means that the current playback progress of the headphone device A3 is faster than that of the headphone device B3, and the headphone device B3 needs to speed up its own playback speed. For another example, when the first clock signal and the second clock signal are not synchronized, it means that the clock signals of the headphone device A3 and the headphone device B3 are not synchronized, and the difference between the clock signals needs to be referenced when adjusting the playback speed of the headphone device B3.

For another example, in one embodiment:

New playback speed = current playback speed + speed compensation (formula 1);

In formula 1, the speed compensation is a parameter value calculated based on the first clock signal, the second clock signal, the first data packet sequence identifier and the second data packet sequence identifier:

Speed Compensation =

f(first clock signal value, second clock signal value, first data packet sequence identification value, second data packet sequence identification value) (Equation 2).

In formula 2, f( ) is a calculation function determined according to the actual scene.

Further, in the embodiment of the present application, the synchronization of the playback progress is performed periodically. Specifically, the playback period is divided according to the preset period setting (for example, every 4 seconds is divided into a playback period), and at the end of a playback period, one headphone device sends a clock signal and a data packet to another headphone device Sequence identifier, the headphone device that receives the clock signal and the data packet sequence identifier adjusts its own playback speed to synchronize the playback progress.

Further, in order to reduce the difficulty of implementation, in an embodiment of the present application, the index parameter and the playback progress synchronization are implemented based on the data packet sequence identifier. Specifically, a sequence (sequence, seq) field is added to the audio data packet. According to the sequence of audio data packets, the value of seq is incremented. The index parameter (seq_map) is a string of binary codes. The data structure of seq_map is defined as: UINT32 seq_map. In seq_map, bit (bit) i indicates whether an audio data packet (i=0, 1, 2 . . . ) is received at the i-th data reception in the data reception cycle. For example, a value of bit i of 1 means that the ith data reception receives an audio data packet, and a value of bit i of 1 means that the ith data reception does not receive an audio data packet.

Set every N data reception as a data reception cycle:

i=seq%N. (3)

Further, in the 1990s, an improvement in a technology can be clearly differentiated between improvements in hardware (for example, improvements to circuit structures such as diodes, transistors, switches, etc.) or improvements in software (improvements in method procedures). ). However, with the development of technology, the improvement of many methods and processes today can be regarded as a direct improvement of the hardware circuit structure. Designers almost get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by hardware entity modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logical function is determined by an accessor programming the device. It is programmed by the designer to "integrate" a digital device on a PLD, without the need for a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, today, instead of making integrated circuit chips by hand, this kind of programming is also mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing, and needs to be compiled before compiling. The original code also has to be written in a specific programming language, which is called Hardware Description Language (HDL), and there is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language) , AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., currently the most commonly used The ones are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that a hardware circuit for implementing the logic method process can be easily obtained by simply programming the method process in the above-mentioned several hardware description languages and programming it into the integrated circuit.

In addition, all or part of these modules can be integrated together, and can also be implemented independently.
