In step S102, the communication parameters related to the wireless link are transmitted to the slave earphone by the other device, so that the slave earphone listens to the wireless link by the received communication parameters related to the wireless link. Specifically, a wireless link is established between the master earphone and the other device, the slave earphone disguises information transmitted from the master earphone to the master earphone from the other device by using relevant communication parameters of the wireless link, the establishment process of the wireless link does not need to be repeated, the audio information received by the master earphone is not needed to be transmitted to the slave earphone through the master earphone, the information transmission between the other device and the master earphone can be realized more efficiently, the time difference of the information received by the master earphone and the slave earphone can be reduced, and the synchronism of the master earphone and the slave earphone is improved. The other device establishes a wireless link with the master earphone to transmit audio information and serves as an information forwarding/relaying device between the master earphone and the slave earphone, so that information forwarding/relaying between the master earphone and the slave earphone is realized without other devices, interference (in a wired mode) from/to the outside can be avoided while safety, reliability and stability of transmission of relevant communication parameters of the wireless link between the master earphone and the slave earphone are ensured, shielding of signals by objects between the earphones can be avoided, resources can be saved, and use experience of users can be improved.
In some embodiments, taking the communication mode of the wireless link as the bluetooth communication mode as an example, the related communication parameters include an encryption information parameter, a bluetooth address of the master earphone, bluetooth frequency hopping information, a bluetooth piconet clock corresponding to the wireless link, and the like. In other communication modes of the wireless link, the relevant communication parameters required for disguising and listening are also different, and usually include address information, encryption information (password), clock, timing sequence, and other information.
Specifically, after the wireless link between the master earphone and the other device is successfully established, the relevant communication parameters of the wireless link may be obtained on both the master earphone and the other device, in some embodiments, the relevant communication parameters of the wireless link may be sent to the other device by the master earphone, so that the relevant communication parameters of the wireless link are transmitted to the slave earphone by using the other device, and in some embodiments, the relevant communication parameters of the wireless link may also be directly obtained from the other device and sent to the slave earphone, so that the information transmission time may be saved.

Fig. 2 is a flowchart illustrating a communication method for a wireless headset according to one embodiment of the present disclosure, as shown in fig. 2, after a wireless link between a master headset and another device is established in step S201, in step S202, relevant communication parameters of the wireless link are transmitted to the another device by the master headset, and in step S203, relevant communication parameters of the wireless link are received by the another device and transmitted to a slave headset, so that the slave headset may pretend to be the master headset to receive information transmitted to the master headset from the another device after receiving the relevant communication parameters of the wireless link.
In some embodiments, the related communication parameters of the wireless link are transmitted to the slave headset by another device through broadcasting, for example, WiFi broadcasting, Bluetooth Low Energy (BLE) broadcasting, and the like, and the related communication parameters of the wireless link can be transmitted to the slave headset far away from the other device in a broadcasting manner, so that the use experience of the user can be improved. In some embodiments, the communication parameters associated with the wireless link may be transmitted by another device to the slave earpiece over a broadcast channel. In some embodiments, the broadcast may be in the form of a non-directional broadcast or a directional broadcast, for example, the other device may directionally broadcast the relevant communication parameters of the wireless link to the slave headset according to the address if the address of the slave headset is known, and for example, the other device may non-directionally broadcast the relevant communication parameters of the wireless link to the slave headset with an unknown address. In some embodiments, the address of the slave earphone may be stored in advance on the other device, so that the other device may directionally broadcast the relevant communication parameters of the wireless link to the slave earphone according to the address of the slave earphone stored in advance, so as to reduce information transmission time and improve the use experience of a user.
In some embodiments, the number of slave earphones is several, as shown in fig. 3, each of the several slave earphones 305 may listen to the audio information transmitted to the master earphone from another device 301 by using the related communication parameters of the wireless link received by each slave earphone 305, so that a plurality of users may listen to the audio information from another device 301 by using the several slave earphones 305 at the same time, which can improve the convenience of the wireless earphones and the user experience.
In some embodiments, the broadcast comprises a Bluetooth Low Energy (BLE) broadcast. Specifically, another device sends out a broadcast data packet from a broadcast channel by using bluetooth low energy, as shown in fig. 4(a), the broadcast data packet includes a packet header and a payload, as shown in fig. 4(b), the packet header includes a type field of the broadcast data packet, a protocol extension field, a channel selection field, an address type field of the other device sending out the broadcast data packet, an address type field of a target device (i.e., a slave) and a payload length field, and the payload includes an address field and a data field (not shown in fig. 4) of the other device sending out the broadcast data packet, wherein related communication parameters of a wireless link are located in the data field in the payload. Specifically, the slave earphone searches for another device which is broadcasting, sends a scanning request data packet to the other device after searching for the other device, the scanning request data packet comprises an address field of the slave earphone and an address field of the other device, the other device sends a scanning response data packet to the slave earphone after receiving the scanning request data packet sent by the slave earphone, and the slave earphone automatically establishes connection with the other device after receiving the scanning request data packet to receive the broadcasting data packet sent by the other device. The Bluetooth Low Energy (BLE) broadcast not only can be with wireless link's relevant communication parameter transmits for the earphone from far away from another equipment, and the consumption is still lower, can save electric power resource when promoting user's use and experience.
In some embodiments, the communication method further comprises: in the event that the correct audio information is received by the master earphone, an error correction code is broadcast by the master earphone to the several slave earphones instead of the audio information. Specifically, the slave earphone may receive wrong audio information from another device, but due to the large data volume of the audio information, in this case, the time taken for the master earphone to transmit correct audio information to the slave earphone is long, which may affect the performance of the master earphone and the slave earphone for receiving audio information from another device. As shown in fig. 5, in the nth frame (N is a natural number greater than 1), audio information is transmitted to the master headset by another device, including but not limited to a smart device such as a cellular phone, a wearable device, etc., and the slave headset receives the audio information by listening. As shown in fig. 6, in the case where the master earphone 604 receives correct audio information, it may be encoded by using an ECC (error correction code) encoder, the encoded result includes the audio information and an ECC code, and the ECC code is transmitted to the plurality of slave earphones 605 in a subsequent period within the nth frame, and if the slave earphones 605 listen to the obtained audio information from another device that is wrong, the ECC code received from the master earphone 604 may be used to correct the wrong audio information via an ECC decoder, so as to obtain correct audio information, without retransmitting the correct audio information from the master earphone 604 to the slave earphones 605, which can ensure that the plurality of slave earphones 605 can obtain correct audio information while significantly reducing the amount of data transmission between the master earphone 604 and the slave earphones 605.
In some embodiments, the communication method further comprises: determining the storage conditions of the master earphone and the slave earphone; in the case that at least one of the master earphone and the slave earphone is taken out of the charging box, transmitting the relevant communication parameters of the wireless link to the slave earphone by using another device, so that the slave earphone listens to the wireless link by using the received relevant communication parameters of the wireless link; and transmitting the related communication parameters of the wireless link from the master earphone to the slave earphone in a wired manner via the charging box in a case where both the master earphone and the slave earphone are accommodated in the charging box. In particular, in some embodiments, the charging box may not only act as a charging device for the master-slave earphone, but it may also act as an information forwarding/relaying device between the master earphone and the slave earphone for relaying relevant communication parameters of the wireless link between the master earphone and the other device between the master earphone and the slave earphone. In particular, when the master earphone and the slave earphone are both accommodated in the charging box, the charging box can be used for transmitting the related communication parameters of the wireless link from the master earphone to the slave earphone in a wired manner, so that the transmission of the related communication parameters of the wireless link between the master earphone and the slave earphone is safer, more reliable and more stable, interference from/to the outside (wired manner) is avoided, and/or the shielding of signals by objects between the earphones is avoided, in the case that at least one of the master earphone and the slave earphone is taken out of the charging box, the related communication parameters of the wireless link are transmitted to the slave earphone by using another device, so that the slave earphone can listen to the wireless link by using the received related communication parameters of the wireless link, and resources can be saved while ensuring that the transmission of the related communication parameters of the wireless link between the master earphone and the slave earphone is safer, more reliable and more stable, the use experience of the user can be improved.
In some embodiments, the communication method further comprises: before establishing a wireless link between the master earphone and another device, the address of the master earphone and the address of the slave earphone are set to be the same address in advance, for example, the address of the master earphone and the address of the slave earphone are configured to be the same address in advance when the wireless link is shipped, so that the address information of the earphone can not be transmitted when the related communication parameters of the wireless link are transmitted, the information transmission amount is reduced, and the information transmission speed is improved.
In some embodiments, the communication mode of the wireless link comprises at least one of bluetooth, Bluetooth Low Energy (BLE), ANT, RF4CE, Zigbee, Near Field Communication (NFC). In different communication modes of a wireless link, related communication parameters required for disguising and listening are correspondingly different, and usually include address information, encryption information (password), clock, timing sequence and other information.
In some embodiments, transmitting the related communication parameters of the wireless link to the slave headset using another device comprises: the related communication parameters of the wireless link are directly obtained by the other device and transmitted to the slave earphone by the other device. Specifically, after the wireless link is established between the other device and the master earphone, the other device can also acquire and store the relevant communication parameters of the wireless link, and the other device directly obtains the relevant communication parameters of the wireless link from the other device and transmits the relevant communication parameters to the slave earphone without transmitting the relevant communication parameters of the wireless link from the master earphone to the other device, so that the information transmission time and the communication resources can be saved, the slave earphone can more quickly receive the relevant communication parameters of the wireless link, and the use experience of a user is improved.
In some embodiments, the application layer of the other device directly obtains the relevant communication parameters of the wireless link from the underlying layer of the other device via the application programming interface and transmits the relevant communication parameters of the wireless link to the slave headset. Specifically, the other device may include a processor and a memory, the memory may store an operating system and various application programs, and the like, and the processor may implement corresponding operations when executing the operating system and various application programs. The bottom layer of the other device may include a bottom layer of a wireless module (e.g., without limitation, a BLE communication module, etc.) in communication with the primary headset. After the wireless link is established between the master earphone and the other device, the related communication parameters of the wireless link can be obtained and stored from the bottom layer of the communication module of the other device, which establishes the wireless link with the master earphone, the application program has the right to obtain data from the bottom layer of the other device, and the related communication parameters of the wireless link can be directly obtained from the bottom layer of the other device through the programming interface of the application program.

In some embodiments, the broadcast may be in the form of a non-directional broadcast or a directional broadcast, for example, the other device 701 may directionally broadcast the relevant communication parameters of the wireless link to the slave headset 705 according to the address when the address of the slave headset 705 is known, and for example, the other device 701 may non-directionally broadcast the relevant communication parameters of the wireless link to one or more slave headsets 705 of unknown addresses. In some embodiments, the address of the slave headset 705 may be pre-stored on the other device 701, so that the other device 701 may directionally broadcast the relevant communication parameters of the wireless link to the slave headset 705 according to the pre-stored address of the slave headset 705, which may reduce the transmission time of information from the slave headset 705 to the other device 701, thereby improving the user experience.
In some embodiments, the number of the slave earphones 705 is several, and each of the several slave earphones 705 may listen to the information transmitted to the master earphone 704 from the other device 701 by using the related communication parameters of the wireless link received by each slave earphone 705, so that a plurality of users may listen to the information from the other device 701 by using the several slave earphones 705 at the same time, thereby improving the convenience of the wireless earphones and the user experience.
In some embodiments, the broadcast mode comprises Bluetooth Low Energy (BLE) broadcast. Specifically, a broadcast packet sent by another device 701 from a broadcast channel by using bluetooth low energy is received from a headset 705, the broadcast packet includes a packet header and a payload, the packet header includes a type field of the broadcast packet, a protocol extension field, a channel selection field, an address type field of the other device 701 sending the broadcast packet, an address type field of a target device (i.e., from the headset), and a payload length field, and the payload includes an address field and a data field of the other device 701 sending the broadcast packet, wherein relevant communication parameters of a wireless link are located in the data field in the payload. Specifically, the slave headphone 705 searches for another device 701 that is broadcasting, and after searching for another device 701, sends a scan request packet to the another device 701, where the scan request packet includes an address field of the slave headphone 705 and an address field of the another device 701, and after receiving the scan request packet sent by the slave headphone 705, the another device 701 sends a scan response packet to the slave headphone 705, and after receiving the scan request packet from the headphone 705, automatically establishes a connection with the another device 701 to receive a broadcast packet sent by the another device 701. The low-power consumption Bluetooth (BLE) broadcast may not only transmit the relevant communication parameters of the wireless link to the slave headset 705 that is far from the other device 701, but also have low power consumption, which may save power resources while improving the user experience.
In some embodiments, the primary earpiece 704 is configured to: in case correct audio information is received, error correction codes are broadcast to several slave headphones 705 instead of audio information. Specifically, the slave earphone 705 may receive wrong audio information from the master earphone 704, but due to the large data volume of the audio information, in this case, the time taken for the master earphone 704 to transmit correct audio information to the slave earphone 705 is long, which may affect the performance of the master earphone receiving audio information from the other device 701. In the nth frame (N is a natural number greater than 1) in the timing diagram of the communication method of the wireless headset, the master headset 704 receives audio information transmitted by another device 701, a smart device including but not limited to a cellular phone, a wearable device, etc., and the slave headsets 705 receive the audio information by listening. The master earphone 704 may encode correct audio information with an ECC (error correction code) encoder in a case where it receives the correct audio information, the encoded result including the audio information and the ECC code, and transmit the ECC code to the plurality of slave earphones 705 respectively in a subsequent period within the nth frame, and if the slave earphones 705 listen to the obtained audio information from the other device 701 as being erroneous, the erroneous audio information may be error-corrected via an ECC decoder with the ECC code received from the master earphone 704, thereby obtaining the correct audio information, without the master earphone 704 retransmitting the correct audio information to the slave earphones 705, which can ensure that the correct audio information is obtained from the earphones while significantly reducing the amount of data transmission between the master and slave earphones.
In some embodiments, before the wireless link between the master earphone 704 and the other device 701 is established, the addresses of the master earphone 704 and the slave earphone 705 are preset to the same address, for example, the address of the master earphone 704 and the address of the slave earphone 705 are configured to the same address in advance in factory, so that the address information of the earphones may not be transmitted when the related communication parameters of the wireless link are transmitted, thereby reducing the amount of information transmission and improving the information transmission speed.
In some embodiments, the communication mode of the wireless link comprises at least one of bluetooth, Bluetooth Low Energy (BLE), ANT, RF4CE, Zigbee, Near Field Communication (NFC). In different communication modes of a wireless link, related communication parameters required for disguising and listening are correspondingly different, and usually include address information, encryption information (password), clock, timing sequence and other information.
