[0051] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0052] Bluetooth technology is a short-range wireless communication technology that can transmit data between mobile devices. With the increasing demand for wireless communication and portability, Bluetooth headsets have gradually become one of the common wireless communication devices in people's daily lives. Therefore, with the continuous development of technology, split Bluetooth headsets have gradually become the focus of people's attention. Split Bluetooth headsets can simultaneously receive audio data from the mobile phone and play sounds from different channels through the wireless connection between the left and right earplugs. This design allows users to be more free during use and avoids the constraints and inconveniences brought by wired connections.

[0053] However, during the process of audio data transmission between the split Bluetooth headset and the user device in the related technology, confirmation information can be sent to the user device through the first audio receiving device only after the first audio receiving device completely receives the audio data, which easily leads to long transmission delays and high power consumption on the user device side.

[0054] In order to solve the problems existing in the related art, the present disclosure proposes an audio data transmission method, by allowing any one of the first audio receiving device and the second audio receiving device to send a confirmation message to the user device after receiving the complete audio data, the user device does not need to send the same audio data multiple times, thereby saving the power consumption of the user device, improving the energy efficiency of the user device, extending the use time of the user device, reducing the music freeze, and providing a smoother music experience. At the same time, during the process of synchronous data interaction between the first audio receiving device and the second audio receiving device, only the missing mono audio missing data of the other party needs to be transmitted, saving the power consumption of data exchange between the first audio receiving device and the second audio receiving device.

[0055] The audio data transmission method proposed in the present disclosure is mainly used in the field of Bluetooth headsets, especially for data transmission and power consumption optimization of split Bluetooth headsets. It can be specifically applied to usage scenarios such as wireless music playback and mobile device calls, and is not limited in the embodiments of the present disclosure.

[0056] The audio data transmission method provided by the present application is introduced in detail below with reference to the accompanying drawings.

[0057] Figure 1 The following is a flow chart of an audio data transmission method provided by an embodiment of the present disclosure. Figure 1 As shown, the audio data transmission method is executed by a user equipment UE, which includes but is not limited to intelligent terminal equipment, cellular phones, wireless devices, handheld devices, mobile units, vehicles, vehicle-mounted equipment, etc. The audio data transmission method includes steps 101-102.

[0058] Step 101: Send audio data to a first audio receiving device via a first communication link between the first audio receiving device and the first audio receiving device.

[0059] In the embodiments of the present disclosure, the user device in the present disclosure may specifically refer to an audio source device, that is, the source of audio data, such as a mobile phone, a tablet, etc. The first audio receiving device in the present disclosure may specifically be a left channel speaker or a right channel speaker of a split Bluetooth headset. The first audio receiving device generally refers to a device connected to the user device or paired with other devices by Bluetooth, and is mainly responsible for receiving audio data from the user device and transmitting it to the second audio receiving device, and is also responsible for establishing a Bluetooth connection with the user device and transmitting data.

[0060] Audio data refers to digital sound data, which includes uncompressed audio sampling data raw stream and compressed and encoded audio sampling data.

[0061] In the present disclosure, the first communication link may be an ACL link, which is a type of connection in Bluetooth and is used to transmit data between Bluetooth devices. The ACL link is an asynchronous, bidirectional, reliable data link that can support Bluetooth data transmission and voice transmission at the same time.

[0062] It is understandable that in the present disclosure, the user device only sends audio data to the first audio receiving device. The second audio receiving device can obtain the connection parameters through the third communication link between the second audio receiving device and the first audio receiving device, and monitor the audio data sent by the user device to the first audio receiving device through the second communication link between the second audio receiving device and the user device through the connection parameters to obtain the same audio data as the first audio receiving device.

[0063] Step 102: Receive confirmation information sent by the first audio receiving device or the second audio receiving device through the first communication link or the second communication link with the second audio receiving device.

[0064] In the present disclosure, the confirmation information indicates that the first audio receiving device or the second audio receiving device has completely received the audio data.

[0065] In an embodiment of the present disclosure, the user equipment may receive the confirmation information through the first communication link or through the second communication link between the user equipment and the second audio receiving device.

[0066] Among them, the audio data interaction between the first audio receiving device and the second audio receiving device can be achieved through a third communication link. In the present disclosure, the third communication link can be a hybrid link, namely a Hybrid link, which combines the characteristics of an access link and a relay link to achieve synchronization of audio data.

[0067] The second audio receiving device in the present disclosure can be a left channel speaker or a right channel speaker of a split Bluetooth headset. The second audio receiving device is usually connected to the first audio receiving device via Bluetooth. The second audio receiving device obtains an audio signal from a mobile phone or other device, and transmits it to the first audio receiving device via Bluetooth, and then the first audio receiving device transmits the audio signal to the second audio receiving device.

[0068] In the present disclosure, sending confirmation information refers to replying ACK. ACK (Acknowledge character) is a confirmation character, which is an important mechanism for achieving reliable transmission in data communication. It is a transmission control character sent by the receiver to the sender, indicating that the sent data has been confirmed to be received correctly. In the TCP / IP protocol, if the receiver successfully receives the data, it will reply with an ACK message; if the receiver does not successfully receive the data, it will not send an ACK message. At this time, the sender will resend the data until the correct ACK message is received or the retransmission limit is reached. Usually, the ACK signal has its own fixed format and length, and is replied by the receiver to the sender. The specific format and length are not limited in the embodiments of the present disclosure.

[0069] The second communication link in the present disclosure may be a monitoring link, namely a snoop link, which is used to monitor and capture data in a network to obtain audio data sent by the user device to the first audio receiving device, and to send confirmation information to the user device.

[0070] In summary, according to the audio data transmission method proposed in the present disclosure, audio data is sent to the first audio receiving device through the first communication link between the first audio receiving device and the second audio receiving device; confirmation information sent by the first audio receiving device or the second audio receiving device is received through the first communication link or the second communication link between the first audio receiving device and the second audio receiving device, and the confirmation information indicates that the first audio receiving device or the second audio receiving device has completely received the audio data, so that the confirmation information is sent to the user device through the first audio receiving device or the second audio receiving device. During the audio data transmission process, there is no need to wait for the first audio receiving device to completely receive the audio data before transmitting, thereby reducing the power consumption of the user device and avoiding long transmission time.

[0071] Figure 2 The following is a flow chart of an audio data transmission method provided by an embodiment of the present disclosure. Figure 2 As shown, the audio data transmission method is performed by a first audio receiving device, which may be an electroacoustic transducer for converting audio information into sound, such as a speaker, earphone, earplug, etc. The first audio receiving device may be a left channel speaker or a right channel speaker, which is not limited in the present disclosure. The audio data transmission method includes steps 201-202.

[0072] Step 201: receiving audio data sent by a user equipment via a first communication link with the user equipment.

[0073] In the embodiments of the present disclosure, the user device refers to an audio source device, which may specifically be a terminal device such as a mobile phone or a tablet.

[0074] In the present disclosure, data communication between the user equipment and the first audio receiving device may be achieved by establishing a first communication link (ACLlink) between the user equipment and the first audio receiving device.

[0075] Step 202: Send confirmation information to the user equipment via the first communication link.

[0076] In the present disclosure, the confirmation information indicates that the first audio receiving device has completely received the audio data.

[0077] In an embodiment of the present disclosure, through a first communication link (ACL link) established between a user device (Audio SRC) and a first audio receiving device (SNK1), the first audio receiving device can send confirmation information of having received audio data to the user device. The first audio receiving device sends the confirmation information to the user device based on the judgment result obtained after the first user device verifies the audio data it has received. The first user device verifies the audio data it has received specifically to determine whether the audio data it has received is complete.

[0078] In addition, the first audio receiving device may also perform data interaction with the second audio receiving device, which may be implemented through a third communication link established between the first audio receiving device and the second audio receiving device. The interaction data includes audio missing data and connection parameters.

[0079] In summary, through the method provided by the present invention, audio data sent by the user device is received through the first communication link between the user device and the user device; confirmation information is sent to the user device through the first communication link, so that the confirmation information is sent to the user device through the first audio receiving device, thereby reducing the power consumption of the user device and avoiding long transmission time. At the same time, in the process of synchronous data interaction between the first audio receiving device and the second audio receiving device, only the missing mono audio data of the other party needs to be transmitted, thereby saving the data exchange power consumption of the first audio receiving device and the second audio receiving device.

[0080] based on Figure 2 The embodiment shown, Figure 3 The following further shows a flow chart of an audio data transmission method proposed in the present disclosure. Figure 3 based on Figure 2 In the embodiment shown, step 202 is further defined. Figure 3 In the embodiment shown, step 202 includes step 302 and step 303. Figure 3 As shown, the method comprises the following steps:

[0081] Step 301: Receive audio data sent by a user device through a first communication link with the user device.

[0082] In an embodiment of the present disclosure, the first audio receiving device can receive audio data sent by the user device through a first communication link between the first audio receiving device and the user device. The establishment of the first communication link can be implemented using Bluetooth or other wireless communication protocols, which is not limited in the embodiment of the present disclosure. The present disclosure takes the use of ACL link as an example.

[0083] Step 302: Verify the received audio data to determine whether the received audio data is completely received and obtain a determination result.

[0084] In an embodiment of the present disclosure, the first audio receiving device may perform verification through a packet header of the audio data or a length of the audio data.

[0085] Specifically, checking the header of the data packet specifically includes: in some communication protocols, by adding a header in front of the audio data, the header contains meta information about the audio data, such as data type, data length, etc. The first audio receiving device can determine whether the received audio data is complete by verifying the header information. Checking the length of the audio data specifically includes: the audio data is divided according to a fixed length, for example, the fixed length of each frame is 100 bytes. The first audio receiving device can verify whether the data is received completely by comparing whether the total length of the received audio data is equal to the expected length.

[0086] In the present disclosure, the determination of whether the received audio data is complete can also be achieved through the calculation method of cyclic redundancy check (CRC check). The calculation method of CRC check is to take the data to be sent as input, and perform modulo 2 division operation with a pre-set polynomial, and the remainder obtained is the CRC check code. At the sender, the data plus the CRC check code are sent to the receiver together. At the receiver, the received data is again divided modulo 2 by the same pre-set polynomial. If the remainder is 0, it means that the data transmission is correct, that is, it is determined that the currently received audio data is complete. Otherwise, it means that the data transmission is incorrect, that is, the currently received audio data is incomplete.

[0087] Step 303: Based on the determination result, confirmation information is sent to the user equipment via the first communication link.

[0088] In an embodiment of the present disclosure, if the received audio data is completely received, a confirmation message is sent to the user equipment.

[0089] Among them, in the present disclosure, based on the judgment result, audio data interaction can be performed with the second audio receiving device through the third communication link between the second audio receiving device. The third communication link is configured based on the Bluetooth protocol. The Bluetooth protocol of the third communication link can be Bluetooth 4.0, Bluetooth 5.0, etc. In the present disclosure, the Bluetooth protocol of the third communication link can specifically be Bluetooth 5.0. The transmission rate of the third communication link can be 1Mbps or 2Mbps. In order to better realize the subsequent processing of audio data, in the present disclosure, the transmission rate of the third communication link can use a high rate of 2Mbps for data transmission, and 2Mbps can be represented by LE2M in the present disclosure. The third communication link in the present disclosure can be a hybrid link, i.e., a Hybrid link.

[0090] Specifically, if the received audio data is received completely, the first audio receiving device can receive the second missing information sent by the second audio receiving device through the third communication link, and send the second audio missing data corresponding to the second missing information to the second audio receiving device through the third communication link; if the received audio data is not received completely, the first audio receiving device can send the first missing information to the second audio receiving device through the third communication link, and receive the first audio missing data corresponding to the first missing information sent by the second audio receiving device.

[0091] The first missing information and the second missing information refer to notification information corresponding to the content of the audio data missing from the first audio receiving device and the second audio receiving device. The first audio missing data and the second audio missing data refer to the content of the audio data missing from the first audio receiving device and the second audio receiving device.

[0092] In addition, the first audio receiving device can send connection parameters to the second audio receiving device through the third communication link. The connection parameters are used to connect and communicate with the user device. The connection parameters can specifically be connection parameters such as a key and a clock for communicating with the user device in the current communication link.

[0093] In summary, when the first audio receiving device and the second audio receiving device synchronize data, only the missing mono content of the other party needs to be transmitted, saving power consumption of data exchange between the audio receiving devices, and only the missing audio data in the current channel is transmitted between the first audio receiving device and the second audio receiving device.

[0094] Figure 4 The following is a flow chart of an audio data transmission method provided by an embodiment of the present disclosure. Figure 4As shown, the audio data transmission method is performed by a second audio receiving device, which may be an electroacoustic transducer for converting audio information into sound, such as a speaker, earphone, earplug, etc. The second audio receiving device may be a left channel speaker or a right channel speaker, which is not limited in the present disclosure. The audio data transmission method includes steps 401-402.

[0095] Step 401: Acquire audio data sent by a user device to a first audio receiving device through a second communication link with the user device.

[0096] In the embodiments of the present disclosure, the user device refers to an audio source device, which may specifically be a terminal device such as a mobile phone or a tablet.

[0097] In the present disclosure, data communication between the user device and the second audio receiving device may be achieved by establishing a second communication link (snoop link) between the user device and the second audio receiving device.

[0098] It should be noted that the user device does not send audio data to the second audio receiving device. The second audio receiving device receives connection parameters through the third communication link between the second audio receiving device and the first audio receiving device, and monitors the audio data sent by the user device to the first audio receiving device through the connection parameters on the second communication link.

[0099] Step 402: Send confirmation information to the user equipment via the second communication link.

[0100] In the present disclosure, the confirmation information indicates that the second audio receiving device has completely received the audio data.

[0101] In an embodiment of the present disclosure, through a second communication link (snoop link) established between a user device (Audio SRC) and a second audio receiving device (SNK2), the second audio receiving device can send confirmation information of having received the audio data to the user device. The second audio receiving device sends the confirmation information to the user device based on the judgment result obtained after the second user device verifies the audio data it has received. The second user device verifies the audio data it has received specifically to determine whether the audio data it has received is complete.

[0102] In addition, the second audio receiving device may also perform data exchange with the first audio receiving device, which may be specifically achieved through a third communication link established between the second audio receiving device and the first audio receiving device.

[0103] In summary, through the method provided by the present invention, the audio data sent by the user device to the first audio receiving device is obtained through the second communication link between the user device and the first audio receiving device; through the second communication link, a confirmation message is sent to the user device, so that the confirmation message is sent to the user device by the second audio receiving device, thereby reducing the power consumption of the user device and avoiding a long transmission time. At the same time, in the process of synchronous data interaction between the first audio receiving device and the second audio receiving device, only the missing mono audio data of the other party needs to be transmitted, thereby saving the data exchange power consumption of the first audio receiving device and the second audio receiving device.

[0104] based on Figure 4 The embodiment shown, Figure 5 The following further shows a flow chart of an audio data transmission method proposed in the present disclosure. Figure 5 based on Figure 4 In the embodiment shown, step 402 is further defined. Figure 5 In the embodiment shown, step 402 includes step 502 and step 503. Figure 5 As shown, the method comprises the following steps:

[0105] Step 501: Acquire audio data sent by a user device to a first audio receiving device through a second communication link with the user device.

[0106] In an embodiment of the present disclosure, the second audio receiving device can receive connection parameters sent by the first audio receiving device through a third communication link between the second audio receiving device and the first audio receiving device, and the connection parameters are used to connect and communicate with the user device; based on the connection parameters and the second communication link between the second audio receiving device and the user device, the second audio receiving device receives audio data, that is, monitors the audio data sent by the user device to the first audio receiving device, thereby acquiring the audio data. The establishment of the second communication link can be implemented using Bluetooth or other wireless communication protocols, which is not limited in the embodiments of the present disclosure. In the present disclosure, snooplink is used as an example. The connection parameters can specifically be connection parameters such as a key and a clock that are currently connected to the user device for communication.

[0107] Step 502: verify the acquired audio data to determine whether the acquired audio data is complete and obtain a determination result.

[0108] In an embodiment of the present disclosure, the second audio receiving device may perform verification through a packet header of the audio data or a length of the audio data.

[0109] Specifically, checking the header of the data packet specifically includes: in some communication protocols, by adding a header in front of the audio data, the header contains meta information about the audio data, such as data type, data length, etc. The first audio receiving device can determine whether the received audio data is complete by verifying the header information. Checking the length of the audio data specifically includes: the audio data is divided according to a fixed length, for example, the fixed length of each frame is 100 bytes. The second audio receiving device can verify whether the data is received completely by comparing whether the total length of the received audio data is equal to the expected length.

[0110] In the present disclosure, the determination of whether the received audio data is complete can also be achieved through the calculation method of cyclic redundancy check (CRC check). The calculation method of CRC check is to take the data to be sent as input, and perform modulo 2 division operation with a pre-set polynomial, and the remainder obtained is the CRC check code. At the sender, the data plus the CRC check code are sent to the receiver together. At the receiver, the received data is again divided modulo 2 by the same pre-set polynomial. If the remainder is 0, it means that the data transmission is correct, that is, it is determined that the currently received audio data is complete. Otherwise, it means that the data transmission is incorrect, that is, the currently received audio data is incomplete.

[0111] Step 503: Based on the determination result, confirmation information is sent to the user equipment via the second communication link.

[0112] In an embodiment of the present disclosure, if the acquired audio data is completely acquired, a confirmation message is sent to the user equipment.

[0113] Among them, in the present disclosure, based on the judgment result, audio data can be interacted with the first audio receiving device through the third communication link between the first audio receiving device. The third communication link is configured based on the Bluetooth protocol, and the transmission rate of the third communication link can be a high rate of 2Mbps. In the present disclosure, the transmission rate of the third communication link can be represented by LE2M, and the Bluetooth protocol of the third communication link can specifically be Bluetooth 5.0. The third communication link in the present disclosure can be a hybrid link, i.e., a Hybrid link.

[0114] Specifically, if the acquired audio data is received completely, the second audio receiving device can acquire the first missing information sent by the first audio receiving device through the third communication link, and send the first audio missing data corresponding to the first missing information to the first audio receiving device through the third communication link; if the acquired audio data is not received completely, the second audio receiving device can send the second missing information to the first audio receiving device through the third communication link, and receive the second audio missing data corresponding to the second missing information sent by the first audio receiving device through the third communication link.

[0115] It is understandable that the first audio receiving device and the second audio receiving device send confirmation information after the next preset time interval. If the first audio receiving device and the second audio receiving device do not receive the complete audio data, then no confirmation information is sent, and the user device can resend the audio data after the next preset time interval. The specific time length of the preset time interval in the present disclosure is not limited in the embodiments of the present disclosure.

[0116] In summary, when the first audio receiving device and the second audio receiving device synchronize data, only the missing mono content of the other party needs to be transmitted, saving power consumption of data exchange between the audio receiving devices, and only the missing audio data in the current channel is transmitted between the first audio receiving device and the second audio receiving device.

[0117] Figure 6 FIG. 1 is an interactive diagram of an audio data transmission method according to an embodiment of the present disclosure. The method is executed by a communication system, which includes a user equipment UE, a first audio receiving device and a second audio receiving device, such as Figure 6 As shown, the method includes the following steps.

[0118] Step 601: The user equipment sends audio data to the first audio receiving device through the first communication link between the user equipment and the first audio receiving device;

[0119] Step 602: The second audio receiving device obtains connection parameters through a third communication link between the second audio receiving device and the first audio receiving device;

[0120] Step 603: The second audio receiving device obtains audio data through a second communication link between the second audio receiving device and the user device;

[0121] Step 604: the first audio receiving device and the second audio receiving device exchange audio data via a third communication link;

[0122] Step 605: The first audio receiving device sends confirmation information to the user equipment through the first link, where the confirmation information indicates that the first audio receiving device has completely received the audio data.

[0123] Step 606: The second audio receiving device sends confirmation information to the user equipment through the second communication link, where the confirmation information indicates that the second audio receiving device has completely received the audio data.

[0124] Among them, step 605 and step 606 are determined based on whether the audio data in the current audio data interaction process is complete, which is determined according to actual conditions and is not limited in the embodiments of the present disclosure.

[0125] In the embodiments of the present disclosure, Figure 7 As shown in the connection block diagram of a specific audio data transmission method, a user device (Audio SRC) establishes a first communication link (ACL link) with a first audio receiving device (SNK1), and a second audio receiving device (SNK2) is connected to SNK1 via a third communication link (Hybrid link). The connection parameters between SNK1 and the Audio source and the audio missing data of SNK1 or SNK2 are obtained via the third communication link with a transmission rate of 2Mbps (i.e., LE2M) configured by the Bluetooth protocol. Then, SNK2 establishes a second communication link (snoop link) with the Audio SRC, and monitors the audio data of the Audio SRC and SKN1 via the snooplink.

[0126] like Figure 8 The figure shows an interactive schematic diagram of a specific audio data transmission method provided by the present disclosure. Among them, Audio SRC represents the user device, that is, the device that sends audio data when playing music via Bluetooth, which can be a mobile phone or a watch, etc. SNK1 and SNK2 represent the first audio receiving device and the second audio receiving device, that is, the device that receives and plays audio data when listening to music via Bluetooth, which can be a Bluetooth headset or a speaker, left and right earphones. TX represents sending data. RX represents receiving data. TX(ACK) represents replying ACK to indicate that all current data packets have been received. TX(N) means that SNK1 notifies SNK2 that it has not received the data packet.

[0127] In the disclosed embodiment, when Audio SRC sends audio data, SNK1 and SNK2 receive the audio data at the same time. If SNK1 receives all the data, it will reply ACK in the next preset time interval. If SNK2 does not receive all the audio data, after SNK1 replies ACK, SNK1 and SNK2 will exchange audio data, and SNK1 will send the mono data required by SNK2 to SNK2 through the Hybrid link. If SNK1 does not receive all the audio data, before SNK1 replies ACK, SNK1 and SNK2 have a brief interactive communication, and SNK1 will notify SNK2 that it has not received all the audio data. If SNK2 receives all the audio data, it will reply ACK to Audio SRC on behalf of SNK1. Then after replying ACK, SNK1 and SNK2 will exchange audio data, and SNK2 will send the mono content required by SNK1 to SNK1. If neither SNK1 nor SNK2 receives all the audio data, SNK1 and SNK2 will exchange data, and neither SNK1 nor SNK2 will reply ACK to Audio SRC, and Audio SRC will resend the audio data at the next time interval.

[0128] In summary, according to the communication management method provided by the present disclosure, audio data is sent to the first audio receiving device through the first communication link between the first audio receiving device and the second audio receiving device; confirmation information sent by the first audio receiving device or the second audio receiving device is received through the first communication link or the second communication link between the first audio receiving device and the second audio receiving device, and the confirmation information indicates that the first audio receiving device or the second audio receiving device has completely received the audio data, so that the confirmation information is sent to the user device through the first audio receiving device or the second audio receiving device. During the audio data transmission process, there is no need to wait for the first audio receiving device to completely receive the audio data before transmitting, thereby reducing the power consumption of the user device and avoiding long transmission time.
