Bluetooth headsets usually communicate with devices with Bluetooth functions (such as mobile phones and laptops) to achieve functions such as wireless calls and music playback; Bluetooth headsets establish connections with mobile phones or other Bluetooth devices through built-in Bluetooth chips, and use Bluetooth wireless transmission technology to transmit audio signals; Bluetooth headsets include ‌True Wireless Bluetooth headsets: This type of headset usually consists of two independent earplugs, which are wirelessly connected through Bluetooth technology and can transmit audio without cables or intermediate devices; ‌Neck-hanging Bluetooth headsets‌: This type of headset connects two earplugs through a neckband. Although there are wires, it is more flexible than traditional wired headsets; Bluetooth headsets are suitable for a variety of scenarios, including outdoor sports, commuting, office, etc. They not only provide a convenient wireless connection method, but also because of their small and light characteristics, they are easy to carry and use.‌

[0027] See also Figure 1 , Figure 1 It is a flow chart of a headset communication method provided by an embodiment of the present invention. The headset communication method is applied to a Bluetooth headset and aims to repair missing audio data when the Bluetooth connection is unstable and affects the audio data transmission, so as to ensure the integrity of the audio data transmission.

[0029] For example, the audio transmission request of the mobile terminal may be "headphone music playback", that is, click to play music on the mobile terminal, the mobile terminal transmits audio data to the headphone component through the first wireless communication channel (Bluetooth connection), and the headphone component plays the music through decoding; of course, the audio transmission request of the mobile terminal may also include calls, that is, this method can ensure the integrity of data transmission and smooth calls.

[0030] Step S2: Detecting a first packet loss rate of the audio data during transmission. If the first packet loss rate is greater than a first preset threshold, the earphone component saves the audio data and reminds the mobile terminal to repair the audio data.

[0031] Among them, the first packet loss rate refers to the ratio of the number of data packets lost to the total number of data packets sent during network transmission; the first preset threshold is a standard value set according to actual needs. If the first packet loss rate is less than the first preset threshold, it indicates that the integrity of the audio data reaches the actual set standard value and can be directly decoded and played.

[0032] Step S3: In response to the audio repair request of the mobile terminal, a second wireless communication channel is established between the mobile terminal and the charging box, and a third wireless communication channel is established between the charging box and the earphone assembly. The earphone box receives the audio data sent by the mobile terminal through the second wireless communication channel, and transmits the audio data received by the earphone box to the earphone assembly through the third wireless communication channel.

[0033] Among them, the audio repair request of the mobile terminal is set to be automatically triggered, that is, when the earphone component reminds the mobile terminal that the missing audio data needs to be repaired, the mobile terminal automatically triggers the audio repair request and establishes a second wireless communication channel and a third wireless communication channel; the second wireless communication channel and the third wireless communication channel are data transmission channels established by the Bluetooth connection.

[0034] Step S4: superimpose and repair the audio data received by the earphone component through the first wireless communication channel and the audio data received through the third wireless communication channel to obtain repaired audio data, and decode and play the repaired audio data through the earphone component.

[0035] Among them, the earphone component is provided with a storage module and a repair module, the storage module is used to store audio data with a first packet loss rate greater than a first preset threshold, that is, missing audio data, and audio data received through a third wireless communication channel; the repair module is used to superimpose and repair the audio data stored in the storage module with the audio data received through the third wireless communication channel to ensure the integrity of the audio data and the playback sound quality on the earphone component after the audio data is decoded.

[0036] Please also read Figure 2-3 The earphone assembly includes a first communication unit, and the earphone box includes a second communication unit; the first communication unit and the second communication unit can be used for ranging in this embodiment.

[0039] Step S11, based on the obtained location information of the mobile terminal, measure the distance L1 between the mobile terminal and the earphone assembly through the first communication unit, and determine whether the distance L1 is within a second preset threshold; that is, facing multiple mobile terminals, the distance L1 between the multiple mobile terminals and the earphone assembly can also be determined through step S11.

[0040] Step S12: if the judgment result is that the distance L1 is within the second preset threshold and the mobile terminal is in the Bluetooth connectable area of ​​the earphone component, a connection is established with the earphone component according to the Bluetooth communication identifier of the mobile terminal.

[0041] In some embodiments, the above step S3 further includes: Step S0: Acquire the Bluetooth communication identification and location information of the mobile terminal.

[0042] In this step, the mobile terminal may be a mobile phone, a tablet computer or other device; the number of mobile terminals may be one or more.

[0043] In step S31, based on the obtained location information of the mobile terminal, the distance L2 between the mobile terminal and the charging box is measured through the second communication unit, and it is determined whether the distance L2 is within a third preset threshold; that is, in the face of multiple mobile terminals, the distances L2 between the multiple mobile terminals and the earphone box can also be determined through step S31.

[0044] Step S32: If the judgment result is that the distance L2 is within the third preset threshold and the mobile terminal is in the Bluetooth connectable area of ​​the charging box, a connection is established with the charging box according to the Bluetooth communication identifier of the mobile terminal.

[0045] Step S33, detect the distance L3 between the earphone component and the charging case, and determine whether the distance L3 is within a fourth preset threshold; if the judgment result is that the distance L3 is within the fourth preset threshold, the earphone component and the earphone box establish a third wireless communication channel.
