In a first aspect, the present application provides a method for transmitting audio data, which is applied to a wireless headset. The wireless headset includes a primary wireless transceiver and a secondary wireless transceiver. The method includes: establishing a two-way connection between the primary wireless transceiver and a terminal.

In this application, a two-way transmission link is established between the terminal and the main wireless transceiver. The main wireless transceiver can receive audio data sent by the terminal based on the two-way transmission link, and the sub wireless transceiver can obtain the two-way transmission link from the terminal. After the terminal establishes the link information so that the terminal sends audio data based on the bidirectional transmission link, the secondary wireless transceiver can monitor the audio data based on the link establishment information of the bidirectional transmission link to obtain the audio data sent by the terminal. Since the secondary wireless transceiver obtains the link establishment information of the two-way transmission link from the terminal, the transmission provided by this application is relative to the transmission of the two-way transmission link establishment information by the primary wireless transceiver to the secondary wireless transceiver. The audio data method can reduce the number of times information is exchanged between the primary wireless transceiver and the secondary wireless transceiver, thereby reducing the power consumption of the primary wireless transceiver, making the power consumption of the primary wireless transceiver and the power consumption of the secondary wireless transceiver More balanced.

Optionally, the acquiring, by the secondary wireless transceiver, the link establishment information of the bidirectional transmission link from the terminal includes: establishing, by the secondary wireless transceiver, a first low-power link with the terminal; The wireless transceiver receives the chain establishment information sent by the terminal based on the first low power consumption link.

In a possible implementation manner, a first low-power link is established between the terminal and the secondary wireless transceiver, and the secondary wireless transceiver may obtain the link establishment information based on the first low-power link.

Optionally, the link establishment information is acquired by the terminal when an audio playback instruction is detected, or when the terminal determines that the bidirectional transmission link and the first low-power link are successfully established Acquired.

In this application, when the bidirectional transmission link and the first low power consumption link are successfully established, the terminal can send the link establishment information of the bidirectional transmission link to the secondary wireless transceiver. Of course, the terminal can also send the The secondary wireless transceiver sends link establishment information for a bidirectional transmission link. That is, the secondary wireless transceiver can start listening to the audio data transmitted on the bidirectional transmission link when the bidirectional transmission link and the first low-power link are successfully established, and can also start monitoring the bidirectional transmission chain when there is a voice service. Audio data transmitted on the road, the latter can save the power consumption of the primary and secondary wireless transceivers.

Optionally, before the terminal protects the chain establishment information, before the secondary wireless transceiver receives the chain establishment information sent by the terminal based on the first low power consumption link, the method further includes: When the master wireless transceiver receives the link establishment information acquisition request sent by the terminal, the master wireless transceiver acquires the link establishment information; the master wireless transceiver sends the chain establishment information to the terminal based on the bidirectional transmission link, So that the terminal forwards the link establishment information to the secondary wireless transceiver based on the first low power consumption link.

If the terminal strictly protects the two-way transmission link establishment information, at this time, the main wireless transceiver can obtain the two-way transmission link establishment information, and then send the two-way transmission link establishment information to the terminal, and then the terminal forwards To the secondary wireless transceiver.

Optionally, the method further includes: detecting, by the secondary wireless transceiver, physiological characteristic information of a first user wearing the secondary wireless transceiver, obtaining first detection data, and based on the first low-power link Reporting the first detection data to the terminal, so that the terminal displays the first detection data; the main wireless transceiver detects physiological characteristic information of a second user wearing the main wireless transceiver, and obtains a first Two detection data, and report the second detection data to the terminal based on the bidirectional transmission link or the second low power consumption link, so that the terminal displays the second detection data, and the second low power consumption The link is a wireless link between the terminal and the primary wireless transceiver.

In this application, in addition to acquiring the audio data sent by the terminal, the primary wireless transceiver and the secondary wireless transceiver can also report the detected data to the terminal. That is, in this application, the primary wireless transceiver and the secondary wireless transceiver can also detect the physiological characteristic information of the user who wears it, and report the detected data to the terminal, expanding the application of wireless headsets.

Optionally, the two-way transmission link is a Bluetooth BT link, and the first low-power link and the second low-power link are low-power Bluetooth BLE links.

Because the power consumption required to transmit audio data is greater than the power required to transmit detection data, different links can be used to transmit audio data and detection data to reduce the power consumption of the primary wireless transceiver and the secondary wireless transceiver. For example, BT link is used to transmit audio data, and BLE link is used to transmit detection data.

Optionally, the secondary wireless transceiver sends monitoring result indication information to the primary wireless transceiver based on a third low-power link, and the monitoring result indication information is used to indicate whether the secondary wireless transceiver is at a specified time. The audio data is monitored in the slot, and the third low-power link is a wireless link between the primary wireless transceiver and the secondary wireless transceiver; when the primary wireless transceiver is based on the monitoring The result indication information determines that the secondary wireless transceiver listens to the audio data, and determines that the primary wireless transceiver receives an acknowledgement (acknowledgement, ACK) when the audio data is received within the specified time slot. )information.

In an implementation manner, after the secondary wireless transceiver monitors the audio data, it sends monitoring result indication information to the primary wireless transceiver. The primary wireless transceiver only obtains the audio data after determining that both the secondary wireless transceiver and the primary wireless transceiver obtain audio data. Only when the ACK message is returned to the terminal.

Optionally, after the secondary wireless transceiver sends the monitoring result indication information to the primary wireless transceiver based on the third low-power link, the method further includes: when the primary wireless transceiver determines the monitoring result according to the monitoring result indication information.

The data forwarding link is a wireless link between the primary wireless transceiver and the secondary wireless transceiver.

If the interference information does not successfully interfere with the terminal, the terminal will no longer retransmit the audio data. In this case, the audio data received by the secondary wireless transceiver will be missing. Therefore, the secondary wireless transceiver can Obtain missing audio data at the wireless transceiver.

Optionally, after the secondary wireless transceiver monitors the audio data sent by the terminal unidirectionally based on the chain establishment information, the method further includes: the secondary wireless transceiver monitors the primary wireless transceiver based on the chain establishment information.

detailed description

In order to make the purpose, technical solution and advantages of this application clearer,

Before explaining the embodiments of the present application, the application scenarios of the embodiments of the present application are introduced:

With the development of wireless technology, wireless earphones are more and more popular because they do not need to communicate with the terminal through a wired connection for communication. Because there is no cable between the wireless headset and the terminal, after the terminal sends audio data, how the left and right earphones included in the wireless headset accurately obtain the audio data will directly affect the user experience of the product.

In the related art, the terminal establishes a bidirectional transmission link with one of the left earphone and the right earphone, and the terminal and the right earphone establish a bidirectional transmission link as an example for description. Because a bidirectional transmission link is established between the terminal and the right earphone, the terminal can send audio data to the right earphone based on the bidirectional transmission link. The audio data sent by the terminal includes left channel data and right channel data. In this case, the left earphone can obtain audio data through the following two schemes.

(1) Full forwarding scheme: When the right earphone receives the audio data sent by the terminal, all the received audio data is forwarded to the left earphone. In this case, both the left earphone and the right earphone can obtain the audio data sent by the terminal, and then the left earphone and the right earphone parse the acquired audio data to obtain left channel data and right channel data. After that, the left earphone plays the left channel data in the audio data, and the right earphone plays the right channel data in the audio data.

(2) Semi-forwarding scheme: When the right earphone receives the audio data sent by the terminal, it analyzes the audio data to obtain the left channel data and the right channel data, and then the right earphone sends the left channel data to the left earphone. After the left earphone acquires the left channel data, the left earphone data is played, while the right earphone plays the right channel data in the audio data.

Obviously, in the above two solutions, the right earphone needs to forward the audio data or the left channel data to the left earphone, which will cause the power consumption required by the right earphone to be large, and the power consumption of the left and right earphones may be unbalanced. Therefore, an embodiment of the present application provides a method for transmitting audio data to reduce power consumption of a wireless headset.

Next, the system for transmitting audio data provided in the embodiment of the present application is explained. As shown in FIG. 1, the system 100 includes a terminal 101 and a wireless audio system 102. The terminal 101 and the wireless audio system 102 are wirelessly connected for communication. . The terminal 101 is configured to send audio data, and the wireless audio system 102 is configured to acquire audio data and play the audio data.

The wireless audio system 102 includes a primary wireless transceiver 1021 and a secondary wireless transceiver 1022. The connection between the primary wireless transceiver 1021 and the secondary wireless transceiver 1022 and the terminal will be explained in detail in the following embodiments. Here, Do not elaborate.

In the embodiment of the present application, the primary wireless transceiver 1021 and the secondary wireless transceiver 1022 are transceivers in a wireless headset. In order to facilitate the subsequent description, the structure of the wireless earphone is explained here first.

Among them, wireless headphones are also called wireless stereo audio speakers. Existing wireless headphones usually include a radio frequency (RF) transceiver and two left and right speakers. The term "speaker" as used herein refers to any electroacoustic transducer and includes, but is not limited to, home and professional audio speakers. Wireless headsets can use standard wireless protocols, as well as proprietary wireless protocols or proprietary protocols. The term "standard wireless protocol" or "standard protocol" as used herein refers to any open or publicly available wireless protocol, or any wireless protocol that is a product of a standards organization or special interest group, including but not limited to the Bluetooth wireless protocol and Wi-Fi (based on the IEEE 802.11 standard series of the Institute of Electrical and Electronics Engineers) wireless protocol. The term "proprietary wireless protocol" or "proprietary protocol" as used herein refers to any wireless protocol other than standard wireless protocols.

At present, there are two main types of wireless earphones. One is the left earphone corresponding to a transceiver and the right earphone corresponds to a transceiver, as shown in FIG. 1. For example, True Wireless Earphones (True Wireless Stereo) belong to this type of wireless earphones. True wireless earphones refer to earphones without a cable between the left earphone and the right earphone. The other type is that the left and right earphones of a wireless earphone share a transceiver. For example, a wireless earphone connected by a wired method between the left earphone and the right earphone belongs to this type of wireless earphone. It should be noted that the left earphone or right earphone described in the embodiments of the present application refers to the left or right speaker in the wireless earphone.

Therefore, in one implementation, the system 100 is applied to a scenario in which the left headset corresponds to one transceiver and the right headset corresponds to one transceiver. At this time, the primary wireless transceiver and the secondary wireless transceiver are the same wireless headset. Two transceivers in the. In this case, there are two ways to determine whether the transceiver corresponding to the left headset is the main wireless transceiver or the transceiver corresponding to the right headset in the wireless headset: (1) When the wireless headset leaves the factory, One of the transceiver corresponding to the left earphone and the transceiver corresponding to the right earphone included in the wireless earphone is set as the primary wireless transceiver, and the other is set as the secondary wireless transceiver. (2) Each time a wireless headset is connected to the terminal, the transceiver corresponding to the headset that first establishes a bidirectional transmission link with the terminal is determined as the primary wireless transceiver, and the transceiver corresponding to the remaining headset is determined as the secondary wireless transceiver. In FIG. 1, the transceiver corresponding to the left earphone is a secondary wireless transceiver, and the transceiver corresponding to the right earphone is a main wireless transceiver, which does not limit the embodiment of the present application.

In another implementation, the system 100 is applied to a scenario in which the left and right earphones of a wireless earphone share a single transceiver. At this time, the main wireless transceiver is a transceiver in one wireless earphone, and the secondary wireless transceiver is another transceiver. Transceiver in a wireless headset. In this case, it is equivalent to having two wireless earphones accessing the terminal. When the terminal sends audio data, both of the wireless earphones can obtain the audio data to implement the function of music sharing. The method for determining which of the two transceivers in the two wireless headsets is the primary wireless transceiver and which is the secondary wireless transceiver may be: determining the transceiver in the wireless headset that first establishes a bidirectional transmission link with the terminal as the primary. The wireless transceiver determines the transceiver in the remaining wireless headset as a secondary wireless transceiver. At this time, the system for transmitting audio data provided in the embodiment of the present application may be the system for transmitting audio data shown in FIG. 2, which is not described in detail here.

The transceiver in the wireless headset may be a Bluetooth transceiver, and of course, it may also be another type of wireless transceiver, which is not described in detail in the embodiment of the present application.

Next, the method for transmitting audio data provided in the embodiment of the present application is described in detail. Among them, how to establish a link between the primary wireless transceiver, the secondary wireless transceiver and the terminal will determine how the data is transmitted. It should be noted that, in the embodiment of the present application, there are the following two link relationships between the primary wireless transceiver, the secondary wireless transceiver, and the terminal. The first type of link relationship: The primary wireless transceiver and the terminal are established. Wireless link, a wireless link is also established between the secondary wireless transceiver and the terminal; the second link relationship: a wireless link is established between the primary wireless transceiver and the terminal, and the secondary wireless transceiver is connected to the primary wireless transceiver. There are also wireless links established. The following two embodiments will describe the method for transmitting audio data provided by the embodiments of the present application based on the first link relationship and the second link relationship, respectively.

FIG. 3 is a flowchart of a method for transmitting audio data according to an embodiment of the present application, which is applied to the first link relationship. As shown in FIG. 3, the method includes the following steps:

Step 301: The main wireless transceiver establishes a bidirectional transmission link with the terminal, and receives audio data sent by the terminal based on the bidirectional transmission link.

Because a bidirectional transmission link is established between the terminal and the main wireless transceiver, after the terminal sends audio data based on the bidirectional transmission link, the main wireless transceiver can directly receive audio data based on the bidirectional transmission link.

Among them, the establishment of a bidirectional transmission link between the terminal and the main wireless transceiver means that the terminal and the main wireless transceiver establish a protocol for the bidirectional transmission link in advance, and in the agreement, the encoding method, encryption method and transmission method used by the two parties to send data are agreed. Information such as the point-in-time information used by the data. The terminal sends audio data based on a bidirectional transmission link means that the terminal sends audio data according to information such as an agreed encoding method, encryption method, and time point information. Therefore, the master wireless transceiver can receive audio data according to the information such as the agreed encoding method, encryption method, and point-in-time information, and reply to the terminal based on the two-way transmission link. For the convenience of explanation later, information such as the encoding method, encryption method, and point-in-time information used by the two parties to send data in the agreement is collectively referred to as the information of the two-way transmission link, that is, the two-way transmission link. The link establishment information includes at least one piece of information in the agreement, such as the encoding method, the encryption method, and the point-in-time information used by the parties to send data.

Among them, since any device has a corresponding system clock, and the system clock of one device may be different from the system clock of the other device, the point-in-time information used to send data includes the respective systems of the devices at both ends of the wireless link. Clock information, and point-in-time information when sending data specifically.

Step 302: The secondary wireless transceiver obtains the link establishment information of the bidirectional transmission link from the terminal, and monitors the audio data sent by the terminal unidirectionally based on the link establishment information.

Although the two-way transmission link is a wireless link between the terminal and the main wireless transceiver, if the secondary wireless transceiver can obtain the link establishment information of the two-way transmission link, then the secondary wireless transceiver can be based on the two-way transmission link. Link information monitors audio data in one direction. Among them, the monitoring of audio data by the secondary wireless transceiver based on the link establishment information of the bidirectional transmission link means that after the terminal sends audio data, the secondary wireless transceiver performs signals such as decoding and Decryption and other processing to obtain audio data transmitted on the bidirectional transmission link.

Among them, the audio data sent by the secondary transceiver to the monitoring terminal based on the link establishment information means that the secondary transceiver only monitors the audio data transmitted on the bidirectional transmission link, and does not reply any data to the terminal.

In a possible implementation manner, a first low-power link is established between the terminal and the secondary wireless transceiver. In this case, the secondary wireless transceiver may receive the link establishment information of the bidirectional transmission link sent by the terminal based on the first low power consumption link.

The link establishment information of the two-way transmission link is obtained by the terminal when it detects an audio playback instruction, or it is obtained by the terminal when it is determined that the two-way transmission link and the first low-power link are successfully established. That is, when the primary wireless transceiver and the secondary wireless transceiver successfully access the terminal, the terminal can send the link establishment information of the bidirectional transmission link to the secondary wireless transceiver, so that the secondary wireless transceiver can monitor the two-way transmission link. Audio data transmitted on the Internet. Alternatively, when the terminal detects an audio playback instruction, it indicates that there is currently a voice service. At this time, the terminal sends the link establishment information of the two-way transmission link to the secondary wireless transceiver, which can prevent the secondary wireless transceiver from accessing the terminal. Start monitoring the two-way transmission link at any time to reduce the power consumption of the primary and secondary wireless transceivers.

In addition, in order to prevent the data transmitted by the terminal based on the two-way transmission link from being leaked, the terminal may strictly protect the link establishment information of the two-way transmission link. At this time, the terminal can send a link establishment information acquisition request to the master wireless transceiver. When the master wireless transceiver receives the link establishment information acquisition request sent by the terminal, it obtains the link establishment information of the bidirectional transmission link. The master wireless transceiver is based on the bidirectional transmission. The link sends the bidirectional transmission link establishment information to the terminal, so that the terminal forwards the bidirectional transmission link establishment information to the secondary wireless transceiver based on the first low power consumption link. The timing for the terminal to send the link establishment information acquisition request to the primary wireless transceiver may still be when the primary wireless transceiver and the secondary wireless transceiver successfully access the terminal, or when a voice service currently exists.

The main wireless transceiver sends the two-way transmission link establishment information to the terminal based on the two-way transmission link. The main wireless transceiver packs the two-way transmission link establishment information and sends the packaged information to the terminal. terminal. Subsequently, when the secondary wireless transceiver receives the packetized link-building information, it analyzes the packetized link-building information to obtain the link-building information of the bidirectional transmission link.

Step 303: The secondary wireless transceiver sends monitoring result indication information to the primary wireless transceiver based on the third low-power link. The monitoring result indication information is used to indicate whether the secondary wireless transceiver has monitored audio data within a specified time slot. A low power link is a wireless link between the primary and secondary wireless transceivers.

After the terminal sends audio data, the primary wireless transceiver and the secondary wireless transceiver need to report the reception results to the terminal so that the terminal can determine whether the audio data needs to be retransmitted. In a possible implementation manner, the secondary wireless transceiver reports the monitoring result to the primary wireless transceiver, and then the primary wireless transceiver responds to the terminal with the result of obtaining audio data by both.

When the secondary wireless transceiver determines that the audio data is monitored, the monitoring result indication information sent may be ACK information. When the secondary wireless transceiver determines that the audio data is not monitored, the monitoring result indication information sent may be NACK information. In this case, the third low-power link is a link for transmitting ACK information and NACK information, and therefore, the third low-power link is also commonly referred to as an ACK link. The third low-power link can be any low-power wireless link that can transmit ACK information and NACK information. The embodiment of this application does not limit the specific form of the third low-power link.

In addition, because the third low-power link is only used to transmit monitoring result indication information, a third low-power link can be established when the primary wireless transceiver and the secondary wireless transceiver access the terminal, and then the third low-power link The cost of the link is always present. Of course, it is also possible to establish a third low-power link when there is a voice service and disconnect the third low-power link at the end of the voice service to reduce the power consumption of the primary and secondary wireless transceivers. This embodiment of the present application is here No restrictions.

It should be noted that the information exchange between the terminal, the primary wireless transceiver and the secondary wireless transceiver is performed according to time slots. A time slot refers to a time period, and each time slot has a start time point and an end time point. For example, audio data sent by a terminal is sent within a specified time slot. Therefore, listening to audio data by the secondary wireless transceiver means that the secondary wireless transceiver monitors audio data within the specified time slot.

In addition, when the secondary wireless transceiver determines that no audio data is being monitored, the secondary wireless transceiver may not send any information. In this case, if the primary wireless transceiver does not receive any information from the secondary wireless transceiver, it may also determine the secondary wireless transceiver. The wireless transceiver is not listening to audio data.

Step 304: When the primary wireless transceiver determines that the secondary wireless transceiver listens to the audio data according to the monitoring result indication information, and determines that the primary wireless transceiver receives the audio data within a specified time slot, it returns a confirmation ACK message to the terminal.

In the embodiment of the present application, the secondary wireless transceiver reports the monitoring result to the primary wireless transceiver, and then the primary wireless transceiver uniformly responds to the terminal to obtain the audio data acquisition results. Therefore, only the primary wireless transceiver determines the two. When the audio data is obtained, the ACK message is returned to the terminal.

Correspondingly, when the primary wireless transceiver determines that the secondary wireless transceiver does not listen to audio data in the specified time slot according to the monitoring result indication information, and / or, the primary wireless transceiver determines that the primary wireless transceiver does not receive audio in the specified time slot When data is received, a NACK message is returned to the terminal. That is, if the primary wireless transceiver determines that neither the secondary wireless transceiver nor the primary wireless transceiver has acquired audio data, it will reply a NACK message to the terminal so that the terminal retransmits the audio data.

Optionally, if the primary wireless transceiver determines that neither the secondary wireless transceiver nor the primary wireless transceiver has acquired audio data, the primary wireless transceiver may not send any information. In this case, if the terminal is not in the designated time slot After receiving any information sent by the primary wireless transceiver, it may also be determined that neither the secondary wireless transceiver nor the primary wireless transceiver has acquired audio data, and the terminal may retransmit the audio data at this time.

The above steps 301 to 304 are used to describe how the primary wireless transceiver and the secondary wireless transceiver obtain audio data sent by the terminal. Since the secondary wireless transceiver acquires audio data through monitoring, the primary wireless transceiver does not need to forward audio data to the secondary wireless transceiver. This can reduce the power consumption of the primary wireless transceiver, and thus balance the power consumption of the primary wireless transceiver and the secondary wireless transceiver. Wireless transceiver power consumption.

Further, in the embodiment of the present application, the primary wireless transceiver and the secondary wireless transceiver also have physiological feature information detection functions, for example, can perform motion information detection, health information detection, or sleep information detection. At this time, the main wireless transceiver The transceiver and the secondary wireless transceiver also need to report the detected data to the terminal. For example, the secondary wireless transceiver may report the detected data through step 305 described below, and the primary wireless transceiver may report the detected data through step 306 described below.

Step 305: The secondary wireless transceiver detects the physiological characteristic information of the first user wearing the secondary wireless transceiver, obtains the first detection data, and reports the first detection data to the terminal based on the first low-power link, so that the terminal displays the first -Test data.

Because the power consumption required to report detection data is low, and the first low-power link already exists between the terminal and the secondary wireless transceiver, the secondary wireless transceiver can report the first low-power link to the terminal through the first low-power link. -Test data. When the terminal receives the first detection data reported by the secondary wireless transceiver, it may perform data analysis on the first detection data and display the first detection data after the data analysis. The first detection data may be exercise data, health data, or sleep data.

For example, the first low-power link can be a Bluetooth Low Energy (BLE) link or other types of low-power links. The specific form of the first low-power link in this embodiment of the present application is No restrictions.

Step 306: The main wireless transceiver detects the physiological characteristic information of the second user wearing the main wireless transceiver, obtains the second detection data, and reports the second detection data to the terminal based on the two-way transmission link or the second low power consumption link. For the terminal to display the second detection data, the second low power consumption link is a wireless link between the terminal and the main wireless transceiver.

Because the terminal and the main wireless transceiver already have a two-way transmission link, the main wireless transceiver can report the second detection data to the terminal through the two-way transmission link. When the terminal receives the second detection data reported by the main wireless transceiver, it can perform data analysis on the second detection data and display the second detection data after the data analysis. The second detection data may be exercise data, health data, or sleep data. At this time, the bidirectional transmission link carries the function of transmitting audio data and second detection data at the same time.

In addition, because the requirements for transmitting audio data are relatively high, the power consumption of the main wireless transceiver to transmit audio data based on the bidirectional transmission link is also relatively large, but transmitting such detection data does not actually require such a large power consumption. Therefore, a second low-power link can also be established between the main wireless transceiver and the terminal. In this case, the second low-power link is used to transmit the second detection data, and the two-way transmission link is used to transmit the audio data. To reduce the power consumption of the main wireless transceiver. For example, the two-way transmission link is a Bluetooth (BT) link, and the second low-power link is a BLE link. The BT link can be a Bluetooth Basic Rate (BR) link or an enhanced data rate. (Enhanced Data Rate, EDR) link. Of course, the two-way transmission link and the second low power consumption link may also be other forms of wireless links, which are not limited in the embodiment of the present application.

That is, in the embodiment of the present application, the physiological characteristic information of the first user may be detected by the secondary wireless transceiver, and the physiological characteristic information of the second user may be detected by the primary wireless transceiver, so that the wireless headset has physiological characteristic information detection. Features, expanding the application of wireless headphones. The first user and the second user are different users. For example, the physiological characteristic information of the first user may be detected only by the secondary wireless transceiver, or the physiological characteristic information of the second user may be detected only by the primary wireless transceiver, which is not specifically limited in this embodiment of the present application.

It should be noted that the

above steps

303 and 304 are only a way for the primary and secondary wireless transceivers to report the situation of obtaining audio data to the terminal. In the embodiment of the present invention, the secondary wireless transceiver may send interference information to the terminal. Notify itself that no audio data is being monitored. The implementation manner in which the secondary wireless transceiver sends the interference information to notify the terminal that it has not listened to the audio data will be explained in detail in the embodiment shown in FIG. 5 below, and will not be described here.

It is worth noting that when the secondary wireless transceiver notifies the terminal that it is not listening to audio data by sending interference information, if the primary and secondary wireless transceivers still report detection data through the

above steps

305 and 306, the interference information may Will affect the terminal to receive detection data, so in this case, the master and slave wireless transceivers may not report detection data to the terminal.

In addition, when the primary and secondary wireless transceivers do not report the detection data through the

above steps

305 and 306, after the secondary wireless transceiver monitors the audio data based on the bidirectional transmission link establishment information, it can also monitor the bidirectional transmission link establishment information. Data sent by the master wireless transceiver. In this case, the secondary wireless transceiver releases the first low power consumption link after acquiring the link establishment information of the bidirectional transmission link, so as to reduce the power consumption between the primary and secondary wireless transceivers. In the embodiment of the present application, this monitoring scheme is referred to as a full monitoring scheme. For detailed implementation of the full monitoring scheme, reference may be made to the embodiment shown in FIG. 5, which will not be described here.

Because the primary wireless transceiver and the secondary wireless transceiver in the embodiments of the present application may be two transceivers in the same wireless headset, respectively. It can also be: the main wireless transceiver is a transceiver of a wireless headset, and the secondary wireless transceiver is a transceiver of another wireless headset. The above steps 301 to 306 will be exemplified respectively for these two cases.

Case 1: The left earphone of the wireless earphone corresponds to one transceiver, and the right earphone corresponds to one transceiver. The primary wireless transceiver and the secondary wireless transceiver may be two transceivers in the same wireless headset, respectively.

In case 1, it is assumed that the transceiver corresponding to the left earphone in the wireless earphone is a sub wireless transceiver, and the transceiver corresponding to the right earphone in the wireless earphone is the main wireless transceiver. When the wireless headset is connected to the terminal, the transceiver corresponding to the left headset, the transceiver corresponding to the right headset, and the terminal will establish the link relationship shown in FIG. 4. In FIG. 4, the sub wireless transceiver is corresponding to the left headset. Transceiver, the main wireless transceiver is the transceiver corresponding to the right earphone. As shown in FIG. 4, a bidirectional transmission link is established between the transceiver corresponding to the right earphone and the terminal, a first low power link is established between the transceiver corresponding to the left earphone and the terminal, and the transceiver corresponding to the right earphone is A second low power consumption link is also established between the terminals, and a third low power consumption link is established between the transceiver corresponding to the left earphone and the transceiver corresponding to the right earphone. The two-way transmission link may be a BT link, and the first low-power link, the second low-power link, and the third low-power link may be BLE links.

The terminal has an executable application program corresponding to the wireless headset installed. Therefore, in a possible implementation manner, when the user opens the executable application program through a preset operation, the terminal uses the executable application program to separately communicate with the left headset. The corresponding transceiver and the transceiver corresponding to the right earphone establish the foregoing link.

When the terminal sends audio data, the transceiver corresponding to the right earphone receives audio data based on the bidirectional transmission link, and the transceiver corresponding to the left earphone listens to audio data based on the bidirectional transmission link establishment information, and passes the third low-power link The monitoring result is returned to the transceiver corresponding to the right earphone, and the transceiver corresponding to the right earphone uniformly returns ACK information or NACK information to the terminal.

In addition, when the executable application in the terminal detects that the two-way transmission link and the first low-power link are successfully established, it indicates that both the left earphone and the right earphone exist. At this time, the executable application program can correspond to the left earphone respectively. The transceiver corresponding to the right earphone sends a mono playback instruction, so that the transceiver corresponding to the left earphone controls the left channel of the left earphone to play the audio data, and the transceiver corresponding to the right earphone controls the right earphone to play the audio data. Right channel data in. When the executable application in the terminal only detects that the two-way transmission link is successfully established, it indicates that only the right headset currently exists. At this time, the executable application can send a two-channel playback instruction to the transceiver corresponding to the right headset, so that The transceiver corresponding to the right earphone controls the right earphone to play the left channel data and the right channel data in the audio data, that is, stereo sound is played by the right earphone.

Optionally, when the transceiver corresponding to the right headset does not receive the ACK information reported by the transceiver corresponding to the left headset based on the third low-power link within a certain period of time, the transceiver corresponding to the right headset may automatically control the right headset to play. The left and right channel data in the audio data, that is, the stereo is automatically played by the right earphone.

In addition, the transceiver corresponding to the left earphone reports the first detection data based on the first low-power link, and the transceiver corresponding to the right earphone reports the second detection data based on the second low-power link, that is, the left earphone corresponds to The transceiver reports the first detection data to the executable application, and the transceiver corresponding to the right headset reports the second detection data to the executable application. In this way, the executable application can present the first detection data and the second detection data. To the user.

Case 2: The left and right earphones of a wireless earphone share a transceiver, the main wireless transceiver is a transceiver in one wireless earphone, and the sub wireless transceiver is a transceiver in another wireless earphone.

In Case 2, it is assumed that the transceiver in the wireless headset A is a secondary wireless transceiver, and the transceiver in the wireless headset B is the primary wireless transceiver. When wireless earphone A and wireless earphone B are connected to the terminal, the transceiver in wireless earphone A, the transceiver in wireless earphone B, and the terminal will also establish the link relationship shown in FIG. 4, at this time in FIG. 4 The secondary wireless transceiver is the transceiver in wireless headset A, and the primary wireless transceiver is the transceiver in wireless headset B. As shown in FIG. 4, a bidirectional transmission link is established between the transceiver in the wireless headset B and the terminal, and a first low-power link is established between the transceiver in the wireless headset A and the terminal. A second low-power link is also established between the transceiver and the terminal, and a third low-power link is established between the transceiver in the wireless headset B and the transceiver in the wireless headset A. The two-way transmission link is a BT link, and the first low-power link and the second low-power link are BLE links.

A corresponding executable application program is installed in the terminal. Therefore, in a possible implementation manner, when the user opens the executable application program through a preset operation, the terminal uses the executable application program to communicate with the wireless headset A separately. The transceiver and the transceiver in the wireless headset B establish the aforementioned link.

When the terminal sends audio data, the transceiver in wireless headset B receives audio data based on the bidirectional transmission link, and the transceiver in wireless headset A listens to audio data based on the bidirectional transmission link establishment information, and passes the third low power consumption The link returns the monitoring result to the transceiver in the wireless headset B, and the transceiver in the wireless headset B uniformly returns ACK information or NACK information to the terminal. In addition, whether it is the transceiver in wireless headset A or the transceiver in wireless headset B, after acquiring the audio data, the acquired audio data is parsed, and the left channel data is sent to the corresponding left headset, right The channel data is sent to the corresponding right earphone, so that the corresponding left earphone and right earphone can respectively play the data of the corresponding channel.

In addition, since in the case 2, the left and right earphones in the wireless earphone share a transceiver, so whether wireless earphone A and wireless earphone B both exist, or only one of wireless earphone A and wireless earphone B exists, as long as A transceiver receives the audio data, parses the acquired audio data, and sends the left channel data to the corresponding left earphone, and the right channel data to the corresponding right earphone, so that the corresponding left earphone and right The headset can play the data of the corresponding channel separately.

In addition, the transceiver in wireless headset A can also report the first detection data based on the first low-power link, and the transceiver in wireless headset B can also report the second detection data based on the second low-power link, that is, Yes, the wireless earphone A can report the first detection data to the executable application program, and the wireless earphone B can report the second detection data to the executable application program. In this way, the executable application program can report the first detection data and the second detection data. The data is presented to the user.

In case 2, two users can listen to music at the same time for the purpose of music sharing. And because of the existence of the third low-power link, the reliability and synchronization of music sharing can be guaranteed.

In addition, in the embodiment of the present application, after receiving the audio data and parsing the audio data, the primary wireless transceiver and the secondary wireless transceiver send the channel data synchronized with the playback time information to the corresponding headphones, so that the headphones play The output audio is synchronized audio.

The embodiment shown in FIG. 3 is applied to the first link relationship among the two link relationships provided in the embodiments of the present application. The method for transmitting audio data in the second link relationship is explained below.

FIG. 5 is a flowchart of another method for transmitting audio data provided by the implementation of this application, which is applied to a second link relationship. As shown in Figure 5, the method includes the following steps:

Step 501: The main wireless transceiver establishes a bidirectional transmission link with the terminal, and receives audio data sent by the terminal based on the bidirectional transmission link.

For the implementation manner of step 501, reference may be made to the implementation manner of step 301 in the embodiment of FIG. 3, which is not described in detail here.

Step 502: The secondary wireless transceiver obtains the link establishment information of the bidirectional transmission link from the main transceiver, and unidirectionally monitors the audio data sent by the monitoring terminal based on the link establishment information.

In the embodiment of the present application, no wireless link is established between the secondary wireless transceiver and the terminal, but a separate link is established between the secondary wireless transceiver and the primary wireless transceiver: a data forwarding link. The secondary wireless transceiver can obtain the link establishment information of the bidirectional transmission link based on the data forwarding link. The embodiment of the present application does not limit the specific form of the data forwarding link.

Among them, the main wireless transceiver can send the link establishment information of the bidirectional transmission link to the sub wireless transceiver when the terminal is successfully accessed, or can send the establishment information of the bidirectional transmission link when it is determined that the voice service currently exists. For the secondary wireless transceiver, it will not be described in detail here.

Step 503: The master wireless transceiver replies to the terminal with reception result indication information, and the reception result indication information is used to indicate whether the master wireless transceiver receives audio data within a specified time slot.

Since a data forwarding link has been established between the primary wireless transceiver and the secondary wireless transceiver, if the secondary wireless transceiver reports the monitoring result to the terminal through the primary wireless transceiver, the primary wireless transceiver and the secondary wireless transceiver will interact. There are many times of information, which results in large power consumption of the primary wireless transceiver and the secondary wireless transceiver. Therefore, in the embodiment of the present application, the primary wireless transceiver only reports its own reception result to the terminal, and the secondary wireless transceiver reports the monitoring result through the following step 504.

Wherein, if the main wireless transceiver determines that the audio data is received, the reception result indication information may be ACK information. If the main wireless transceiver determines that the audio data is not received within the designated time slot, the reception result indication information may be NACK information. Of course, if the master wireless transceiver determines that no audio data is received within the designated time slot, the master wireless transceiver may not reply to the terminal with any information.

Step 504: When the secondary wireless transceiver determines that the audio data is not monitored within the designated time slot, the primary wireless transceiver sends interference information in the same time slot as the reply response indication information to the terminal, so that the terminal retransmits the audio data.

In the embodiment of the present application, when the secondary wireless transceiver determines that the audio data is monitored, the secondary wireless transceiver does not perform any operation, and when the secondary wireless transceiver determines that the audio data is not monitored, it sends interference information to the terminal. Because the timing for the secondary wireless transceiver to send interference information is: the primary wireless transceiver replies to the terminal with the same time slot of the reception result indication information. Therefore, if the secondary wireless transceiver sends interference information, the terminal will not be able to recognize the reception result indication information sent by the primary wireless transceiver. In this case, the terminal will determine that the current transmission data has failed and retransmit the audio data. If the terminal can identify the reception result indication information, indicating that the secondary wireless transceiver is not currently sending interference information, the terminal can determine that the secondary wireless transceiver has successfully monitored the audio data, and then determine whether the primary wireless transceiver has successfully received the information based on the reception result indication information. Audio data.

In the embodiment of the present application, if the secondary wireless transceiver sends interference information, but the interference information fails to interfere with the terminal, it is at this time that the primary wireless transceiver successfully receives audio data. In this case, the terminal may not be heavy. The audio data is transmitted, so that the audio data received by the secondary wireless transceiver will be missing. Therefore, the secondary wireless transceiver may periodically report the missing audio data to the primary wireless transceiver through the data forwarding link, so that the primary wireless transceiver forwards the missing audio data to the secondary wireless transceiver.

In a possible implementation manner, the secondary wireless transceiver counts the identifier of the data packet to which each audio data belongs in the multiple audio data that has been received; if the statistical data packet is not a data packet continuously sent by the terminal, the secondary wireless transceiver The transceiver determines at least one missing data packet identifier according to the statistical data packet identifier, and sends at least one missing data packet identifier to the main wireless transceiver based on the data forwarding link; when the main wireless transceiver receives at least one missing data packet identifier , Sending audio data corresponding to each missing packet identifier in the at least one missing packet identifier to the secondary wireless transceiver based on the data forwarding link.

For example, the secondary wireless transceiver counts the identifiers of the data packets that each audio data belongs to in the received multiple audio data are: data packet 1, data packet 2, data packet 4, and data packet 5, then the secondary wireless transceiver It can be determined that the data packet 3 is a missing data packet. At this time, the secondary wireless transceiver can send the identification of the data packet 3 to the primary wireless transceiver based on the data forwarding link, so that the primary wireless transceiver forwards the data packet 3 to the secondary wireless transceiver. .

The

above steps

503 and 504 provide another method for the secondary wireless transceiver to report the monitoring result. Of course, the secondary wireless transceiver may also report the monitoring result through the primary wireless transceiver. In a possible implementation manner, after step 502, the secondary wireless transceiver may report the monitoring result to the terminal through

steps

303 and 304 in the embodiment of FIG. 3, that is, the secondary wireless transceiver passes the third low power The consuming link reports the monitoring result to the main wireless transceiver, and the main wireless transceiver uniformly returns ACK information or NACK information to the terminal. In this case, in order to reduce the interaction information between the primary wireless transceiver and the secondary wireless transceiver, after the secondary wireless transceiver monitors the audio data based on the link establishment information of the bidirectional transmission link, it can also use the bidirectional transmission link establishment information. Listen for data sent by the master wireless transceiver. In this case, the secondary wireless transceiver can release the data forwarding link after obtaining the link establishment information of the bidirectional transmission link, so as to reduce the power consumption of the primary wireless transceiver and the power consumption of the secondary wireless transceiver. The data sent by the main wireless transceiver includes control data sent by the main wireless transceiver based on the bidirectional transmission link.

That is, in the embodiment of the present application, two other differences from the monitoring scheme in the embodiment of FIG. 3 are provided. The first monitoring scheme is the scheme described in the above steps 501 to 504, which may be referred to as "Monitoring + interference + forwarding" scheme, "monitoring" means that the secondary wireless transceiver listens to audio data on the bidirectional transmission link, and "interference" means that the secondary wireless transceiver sends interference information to the terminal when it does not listen to the audio data. "Forwarding" means that the primary wireless transceiver forwards the missing audio data in the secondary wireless transceiver based on the data forwarding link.

At this time, the link relationship established between the primary wireless transceiver, the secondary wireless transceiver, and the terminal is the link relationship shown in FIG. 6. As shown in FIG. 6, a bidirectional transmission chain is established between the terminal and the primary wireless transceiver. The terminal transmits audio data based on the bidirectional transmission link. A data forwarding link is established between the primary wireless transceiver and the secondary wireless transceiver. The secondary wireless transceiver obtains the link establishment information of the two-way transmission link based on the data forwarding link. Monitoring the audio data transmitted by the terminal based on the acquired link establishment information of the bidirectional transmission link, and sending interference information when no audio data is monitored. In addition, the primary wireless transceiver may also forward the audio data missing from the secondary wireless transceiver to the secondary wireless transceiver based on the data forwarding link.

The second scheme is a scheme composed of the

above steps

501, 502, step 303, and step 304. This scheme can be referred to as the "full listening" scheme. "Full listening" means that the secondary wireless transceiver not only monitors the terminal based on the bidirectional transmission chain The data transmitted on the channel is also monitored by the main wireless transceiver based on the data sent on the bidirectional transmission link. This can enable the secondary wireless transceiver to release the data forwarding link after obtaining the link establishment information of the bidirectional transmission link. The power consumption of the primary wireless transceiver and the power consumption of the secondary wireless transceiver.

At this time, the link relationship established between the primary wireless transceiver, the secondary wireless transceiver, and the terminal is the link relationship shown in FIG. 7. As shown in FIG. 7, a bidirectional transmission chain is established between the terminal and the primary wireless transceiver. The terminal transmits audio data based on a bidirectional transmission link, and a data forwarding link is established between the primary wireless transceiver and the secondary wireless transceiver. The secondary wireless transceiver obtains the link establishment information of the bidirectional transmission link based on the data forwarding link, monitors the audio data transmitted by the terminal based on the obtained link establishment information of the bidirectional transmission link, and transmits and receives to and from the main wireless based on the third low-power link The transceiver reports the monitoring results, and the primary wireless transceiver reports the situation in which the primary wireless transceiver and the secondary wireless transceiver obtain audio data to the terminal. In the link relationship shown in FIG. 7, the secondary wireless transceiver not only monitors the data sent by the terminal based on the two-way transmission link, but also listens to the data transmitted by the primary wireless transceiver based on the two-way transmission link. In this case, the secondary wireless transceiver After obtaining the link establishment information of the bidirectional transmission link, the data forwarding link can be released to reduce the power consumption of the primary wireless transceiver and the power consumption of the secondary wireless transceiver.

It should be noted that, in the embodiment shown in FIG. 5, the primary wireless transceiver and the secondary wireless transceiver can still report detection data to the terminal. In this case, the primary wireless transceiver and the secondary wireless transceiver can use FIG. 3 The method of step 305 and step 306 in the embodiment reports the detection data, which will cause too many links to be established, thereby increasing the power consumption of the primary wireless transceiver and the secondary wireless transceiver. Alternatively, the secondary wireless transceiver first reports the first detection data to the primary wireless transceiver through the data forwarding link, and then the primary wireless transceiver forwards the first detection data to the terminal, and also reports the second detection data detected by itself to the terminal. Terminal, the embodiments of the present application are not specifically limited herein.

In the embodiment of the present application, there is a two-way transmission link between the terminal and the primary wireless transceiver, and there is a data forwarding link between the primary wireless transceiver and the secondary wireless transceiver. Therefore, the secondary wireless transceiver can be based on the data forwarding link. After acquiring the link establishment information of the bidirectional transmission link so that the terminal sends audio data based on the bidirectional transmission link, the secondary wireless transceiver can listen to the audio data based on the establishment information of the bidirectional transmission link to obtain the audio data sent by the terminal. When the secondary wireless transceiver determines that the audio data is not monitored within the specified time slot, the primary wireless transceiver sends interference information in the same time slot as the feedback result indication information to the terminal, so that the terminal retransmits the audio data and avoids the primary wireless transceiver The transceiver forwards the monitoring results of the secondary wireless transceiver to reduce the power consumption of the primary wireless transceiver.
