[0037] Wireless earphones, by removing the restraint of physical cables, enable people to make calls or listen to audio more conveniently. Wireless earphones usually include two earphone bodies, which can be respectively called the first earphone and the second earphone. For example, the first earphone can be the left earphone, and the second earphone can be the right earphone. Currently, the two earphones of wireless earphones can respectively establish a Bluetooth connection with an electronic device (such as a mobile phone), and then realize answering the calls of the electronic device. During the process of answering the call of the electronic device, only the microphone of one of the two earphones is turned on to collect voice data.

[0038] The embodiment of the present application provides a voice intercom method, which can realize voice intercom through the two earphones of wireless earphones. Microphones can be set on both of the two earphones of the wireless earphones. For example, the first earphone is provided with a first microphone, and the second earphone is provided with a second microphone. Both earphones can be used as voice input / output devices. In this way, the two earphones are respectively worn by two objects (such as users), and the voice intercom between the two objects can be conveniently realized without relying on other electronic devices (such as mobile phones).

[0039] Please refer to Figure 1 , Figure 1 which is a schematic diagram of an application scenario of the embodiment of the present application. In Figure 1 , the first earphone and the second earphone can be directly connected without relying on other electronic devices, and the voice intercom between the two objects can be realized. As Figure 1 shown, the first object can wear the first earphone, and the second object can wear the second earphone. Among them, in response to the first earphone intercom instruction, the first earphone can turn on the first microphone. Then, the first earphone can collect the first voice data of the first object through the first microphone and send the first voice data to the second earphone. Correspondingly, in response to the second earphone intercom instruction, the second earphone can turn on the second microphone. Then, the second earphone can collect the second voice data of the second object through the second microphone and send the second voice data to the first earphone. In this way, the voice intercom between the two objects is realized.

[0040] In the embodiment of the present application, the wireless earphones can be true wireless stereo (TWS) earphones or open wearable stereo (OWS) wireless earphones, etc. In terms of specific forms, they can be in-ear, semi-in-ear, ear-hanging, ear-clipping, etc. The embodiment of the present application does not make a limitation.

[0041] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the hardware structure of the wireless earphones provided by the embodiment of the present application. Taking one of the earphones of the wireless earphones (such as the first earphone) as an example, as Figure 2As shown, the first earphone may include: a processor 201, a memory 202, a sensor 203, a wireless communication module 204, a receiver 205, a microphone 206, and a power supply 207.

[0042] Among them, the memory 202 can be used to store application code, such as application code for establishing a wireless connection between the first earphone and the second earphone, or for connecting the first earphone to an electronic device. The memory 202 can also store the Bluetooth address for uniquely identifying the first earphone, as well as the Bluetooth address of the second earphone. Optionally, the memory 202 can also store the historical records of the electronic devices connected by the first earphone. For example, the historical records can include the Bluetooth addresses of the electronic devices connected by the first earphone.

[0043] The processor 201 can control the first earphone to execute the above application code to establish a wireless connection between the first earphone and the second earphone, or to connect the first earphone to an electronic device.

[0044] The sensor 203 can be various distance sensors such as a proximity light sensor, or a capacitance sensor, a human body static electricity sensor, etc. The first earphone can determine whether it is worn by the user through the sensor 203. For example, the first earphone can use the proximity light sensor to detect whether there is an object near the first earphone, so as to determine whether the first earphone is worn by the user. When it is determined that the first earphone is worn, the first earphone can turn on the receiver 205 and / or the microphone 206. In some embodiments, the first earphone can also include a touch sensor for detecting the user's touch operation, and the user can adjust some parameters, such as the volume size, through the touch operation.

[0045] The wireless communication module 204 is used to support short-distance communication between the first earphone and other devices (such as the second earphone, the electronic device). In some embodiments, the wireless communication module 204 can be a Bluetooth transceiver. The first earphone can establish a wireless connection with the second earphone through the Bluetooth transceiver to achieve short-distance communication between the two.

[0046] The receiver 205, which can also be called a "receiver", can be used to convert an audio electrical signal into a sound signal and play it.

[0047] The microphone 206, which can also be called a "microphone", "transmitter", can be used to convert a sound signal into an audio electrical signal.

[0048] The power supply 207 can be used to supply power to each component included in the first earphone. In some embodiments, the power supply 207 can be a battery, such as a rechargeable battery.

[0049] It can be understood that the structure schematically shown in the embodiments of the present application does not constitute a specific limitation on the first earphone. The first earphone can have moreFigure 2 More or fewer components as shown may combine two or more components or may have different component configurations. In the embodiments of the present application, the structure of the second earphone may be the same as that of the first earphone. For example, the second earphone may include Figure 2 the components shown.

[0050] In some embodiments, the wireless earphones may be configured with an earphone case, which can be used to place and control the first earphone and the second earphone. Exemplarily, please refer to Figure 3 , Figure 3 which is a schematic diagram of an earphone case provided by an embodiment of the present application. As Figure 3 shown, the earphone case 31 may be provided with an earphone pairing button 301. In one implementation, the earphone pairing button 301 can be used to control the first earphone and the second earphone to pair with each other, and can also be used to control the first earphone and the second earphone in the earphone case to pair with an electronic device. In another implementation, the earphone case 31 may further be provided with a device pairing button. The earphone pairing button 301 is used to control the first earphone and the second earphone to pair with each other, and the device pairing button can be used to control the first earphone and the second earphone in the earphone case to pair with an electronic device. In the embodiments of the present application, to implement the voice intercom function, both the first earphone and the second earphone need to turn on the microphone. Optionally, the earphone pairing button 301 can also be used to turn on the first microphone of the first earphone and the second microphone of the second earphone. Optionally, the earphone case 31 may be provided with a voice intercom button 302, which can be specifically used to turn on the first microphone and the second microphone. In addition, the earphone case 31 may further be provided with a charging port, which can be used to charge the earphone case 31. When the first earphone and the second earphone are placed in the earphone case 31, the earphone case 31 can charge the first earphone and the second earphone.

[0051] It can be understood that Figure 3 the structure of the earphone case shown is only for exemplary illustration and does not limit the structure or function of the earphone case.

[0052] Next, the voice intercom method of the embodiments of the present application will be described in detail.

[0053] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of a voice intercom method provided by an embodiment of the present application. As Figure 4 shown, the voice intercom method may include but is not limited to the following steps:

[0054] S401, in response to a first earphone intercom instruction, the first earphone turns on the first microphone and acquires first voice data through the first microphone.

[0055] Optionally, the first headset intercom instruction may be an instruction generated by the first headset in response to a first headset intercom operation; or, the first headset intercom instruction may be an intercom instruction received by the first headset from the second headset; or, the first headset intercom instruction may be an intercom instruction received by the first headset from the first headset case, where the first headset case can be used to place and control the first headset and the second headset, and the first headset case may be, for example, Figure 3 the headset case shown. The first headset turning on the first microphone can be understood as the first headset turning on the voice intercom function.

[0056] In some embodiments, the first headset intercom instruction may be received when the first headset detects first wearing information, and the first wearing information can be used to indicate that the first headset is in a worn state. In this case, the first headset intercom instruction may be an instruction generated by the first headset in response to a first headset intercom operation. Among them, the first headset intercom operation may be, for example, a touch operation on the first headset by the first object wearing the first headset, or may be a tapping operation on the first headset. That is to say, after the first headset is worn by the first object, it can detect the first headset intercom operation of the first object, and in the case of detecting the first headset intercom operation, it can generate a first headset intercom instruction in response to the first headset intercom operation, and then turn on the headset intercom function of the first headset, that is, turn on the first microphone.

[0057] In some embodiments, one of the first headset and the second headset can be used as the master headset and the other as the slave headset. For example, the second headset is used as the master headset and the first headset is used as the slave headset. In this case, the master headset can send the received headset intercom instruction to the slave headset, that is, the first headset intercom instruction may be an intercom instruction received by the first headset from the second headset.

[0058] In some embodiments, the first headset intercom instruction may be received when the first headset is placed in the first headset case. Optionally, the first headset case may be provided with a pairing button, and the pairing button may be used to trigger a pairing instruction to instruct the first headset and the second headset to pair. Here, the pairing of the first headset and the second headset can be understood as establishing a connection between the first headset and the second headset based on a communication protocol. For example, a Bluetooth connection can be established based on the Bluetooth protocol. Before performing step S401, the first headset and the second headset may first establish a pairing relationship, that is, establish a connection. Here, the pairing button can also be used to trigger the first headset intercom instruction. The operation of triggering the pairing instruction and the operation of triggering the first headset intercom instruction can be different to facilitate the distinction of different instructions. For example, the operation of triggering the pairing instruction can be a single click operation on the pairing button, and the operation of triggering the first headset intercom instruction can be a double click operation on the pairing button. Another example is that the operation of triggering the pairing instruction can be a long press operation on the pairing button within a first time range (such as 3 seconds), and the operation of triggering the first headset intercom instruction can be a long press operation on the pairing button within a second time range (such as 6 seconds). Optionally, the first headset case may also be provided with a voice intercom button, and the voice intercom button can be specifically used to trigger a headset intercom instruction (such as the first headset intercom instruction). The operation of triggering the first headset intercom instruction can include a click operation (such as a single click or a double click) on the voice intercom button, or a long press operation on the voice intercom button.

[0059] In some embodiments, after the first headset turns on the first microphone, first initial voice data can be collected through the first microphone. The first initial voice data may include first voice data and first noise data. The first voice data can be, for example, voice data from a first object, and the first noise data can be, for example, ambient noise data. The decibel value of the first voice data can be higher than that of the first noise data. The first headset can eliminate the first noise data from the first initial voice data to obtain the first voice data. Here, the ambient noise data may be the voice data of a second object. That is, when the distance between the first object and the second object is small, if the first object and the second object speak simultaneously, the first microphone may collect the voice data of the second object. The first headset can eliminate the voice data of the second object from the first initial voice data based on the timbre characteristics of the first object and the timbre characteristics of the second object to obtain the first voice data.

[0060] In some embodiments, after the first earphone acquires first voice data through the first microphone, it may turn off the first microphone in response to a first intercom shutdown operation. The first intercom shutdown operation may be, for example, an operation such as tapping, touching, or swiping on the first earphone. Optionally, the first earphone intercom operation may be a tapping operation on a first part of the first earphone, and the first intercom shutdown operation may be a tapping operation on a second part of the first earphone. The first part and the second part may be the same part or different parts. In this way, the user wearing the first earphone can turn on the first microphone each time voice intercom is needed and turn off the first microphone after the voice intercom ends, achieving flexible management of the first microphone while also helping to reduce the power consumption of the first earphone.

[0061] S402. The first earphone sends the first voice data to the second earphone based on the first communication link. Correspondingly, the second earphone receives the first voice data from the first earphone based on the first communication link.

[0062] Wherein, the first communication link is the communication link between the first earphone and the second earphone, that is, based on the first communication link, the first earphone and the second earphone can directly establish a connection without the aid of an electronic device. Optionally, the first communication link may be a Bluetooth communication link, and the first earphone and the second earphone can directly establish a connection based on the Bluetooth protocol.

[0063] In some embodiments, before the first earphone sends the first voice data to the second earphone based on the first communication link, the first earphone and the second earphone may first be paired. Among them, the first earphone and the second earphone may be placed in the first earphone case for pairing. Optionally, the first earphone case may be provided with a pairing button. In response to a trigger operation on the pairing button, the first earphone case may generate a pairing instruction, and then control the first earphone and the second earphone to perform a pairing connection based on the pairing instruction. Optionally, the first earphone case may send the pairing instruction to the master earphone among the two earphones, and the master earphone, in response to the pairing instruction, may send a pairing connection request to the slave earphone to control the slave earphone to perform a pairing connection.

[0064] In some embodiments, the first earphone and the second earphone may also establish a connection through an electronic device. In this case, the first earphone may establish a first sub-link with the electronic device, and the second earphone may establish a second sub-link with the electronic device. It can be understood that the first communication link between the first earphone and the second earphone is composed of the first sub-link and the second sub-link. The first sub-link is the communication link between the first earphone and the electronic device, and the second sub-link is the communication link between the second earphone and the electronic device. The way for the first earphone to send the first voice data to the second earphone may include the first earphone first sending the first voice data to the electronic device based on the first sub-link, and then the electronic device sending the first voice data to the second earphone based on the second sub-link.

[0065] In some embodiments, due to the limited communication distance between the first earphone and the second earphone, the first earphone can detect the distance between the first earphone and the second earphone, for example, it can be detected periodically. In response to the distance between the first earphone and the second earphone being greater than or equal to the distance threshold, the first earphone can output a first distance prompt message and send a distance prompt instruction to the second earphone. Then, based on the distance prompt instruction, the second earphone can output a second distance prompt message. Here, the first distance prompt message and the second distance prompt message can be used to prompt to shorten the distance between the first earphone and the second earphone. Optionally, the first distance prompt message and the second distance prompt message can be voice messages. For example, the first earphone and the second earphone can output a voice of "Please get closer to the other earphone".

[0066] S403. In response to the second earphone intercom instruction, the second earphone turns on the second microphone and acquires second voice data through the second microphone.

[0067] Optionally, step S403 and step S401 can be executed simultaneously or sequentially. For example, step S401 is executed first, and then step S403 is executed. That is to say, the first earphone and the second earphone can turn on the microphones simultaneously, or the first earphone can turn on the first microphone first. After the first earphone successfully turns on the first microphone, the second earphone then turns on the second microphone. Among them, the second earphone turning on the second microphone can be understood as the second earphone turning on the voice intercom function.

[0068] Optionally, the second earphone intercom instruction can be an instruction generated by the second earphone in response to the second earphone intercom operation; or, the second earphone intercom instruction can be an intercom instruction received by the second earphone from the first earphone; or, the second earphone intercom instruction can be an intercom instruction received by the second earphone from the first earphone case. In some embodiments, the second earphone intercom instruction can be received when the second earphone detects the second wearing information, and the second wearing information can be used to indicate that the second earphone is in a wearing state. In this case, the second earphone intercom instruction can be an instruction generated by the second earphone in response to the second earphone intercom operation. Among them, the second earphone intercom operation can be, for example, a touch operation on the second earphone by the second user wearing the second earphone, or a tapping operation on the second earphone. That is to say, after the second earphone is worn by the second user, it can detect the second earphone intercom operation of the second user. When detecting the second earphone intercom operation, it can generate a second earphone intercom instruction in response to the second earphone intercom operation, and then turn on the earphone intercom function of the second earphone, that is, turn on the second microphone.

[0069] Optionally, the second earphone may receive a second earphone intercom instruction when receiving all or part of the voice data in the first voice data. That is to say, the voice intercom between the first earphone and the second earphone can be two-way. That is, while the first user conducts an intercom through the first earphone, the second user can also conduct an intercom through the second earphone.

[0070] In some embodiments, the first earphone may serve as the master earphone, and the second earphone may serve as the slave earphone. In this case, the first earphone may send the received earphone intercom instruction to the second earphone, that is, the second earphone intercom instruction may be an intercom instruction received by the second earphone from the first earphone.

[0071] In some embodiments, the second earphone intercom instruction may be received when the second earphone is placed in the first earphone case. Optionally, the second earphone intercom instruction may be an instruction sent by the first earphone case to the second earphone in response to an intercom trigger operation. Optionally, the first earphone case may be provided with a pairing button, and the intercom trigger operation may be an operation on the pairing button. The first earphone case may also be provided with a voice intercom button, and the intercom trigger operation may also be an operation on the voice intercom button.

[0072] Optionally, the first earphone case may send the first earphone intercom instruction and the second earphone intercom instruction simultaneously, that is, the first earphone and the second earphone can simultaneously activate the voice intercom function. For example, the first earphone case may control the first earphone and the second earphone to pair and activate the voice intercom function when detecting a trigger operation on the pairing button. Another example is that the first earphone case may also control the first earphone and the second earphone to activate the voice intercom function when detecting a trigger operation on the voice intercom button.

[0073] Optionally, the first earphone case may also send the first earphone intercom instruction and the second earphone intercom instruction separately. For example, the first earphone case may be provided with two different voice intercom buttons, such as a first voice intercom button and a second voice intercom button. When detecting a trigger operation on the first voice intercom button, it sends the first earphone intercom instruction to the first earphone, and when detecting a trigger operation on the second voice intercom button, it sends the second earphone intercom instruction to the second earphone. Another example is that the first earphone case may be provided with only one voice intercom button. When detecting a first trigger operation (such as a single click) on the voice intercom button, it sends the first earphone intercom instruction to the first earphone, and when detecting a second trigger operation (such as a double click) on the voice intercom button, it sends the second earphone intercom instruction to the second earphone.

[0074] S404. The second earphone sends second voice data to the first earphone based on the first communication link. Correspondingly, the first earphone receives the second voice data from the second earphone based on the first communication link.

[0075] Optionally, the sending time of the first voice data may be earlier than the sending time of the second voice data. That is, the voice intercom between the first earphone and the second earphone may be in a half-duplex mode. At the same moment, the first earphone sends the first voice data to the second earphone based on the first communication link, or the second earphone sends the second voice data to the first earphone based on the first communication link. The sending time of some voice data in the first voice data may also be the same as the sending time of some voice data in the second voice data. That is, the voice intercom between the first earphone and the second earphone may also be in a full-duplex mode. At the same moment, the first earphone may send the first voice data to the second earphone based on the first communication link, and the second earphone may also send the first voice data to the first earphone based on the first communication link.

[0076] In some embodiments, the first earphone and the second earphone may also establish a connection through an electronic device. The first communication link between the first earphone and the second earphone may be composed of a first sub-link and a second sub-link. The manner in which the second earphone sends the second voice data to the first earphone may include that the second earphone first sends the second voice data to the electronic device based on the second sub-link, and then the electronic device sends the second voice data to the first earphone based on the first sub-link.

[0077] In some embodiments, the second earphone may receive a distance prompt instruction from the first earphone, and based on the distance prompt instruction, the second earphone may output a second distance prompt message. Optionally, the second earphone may also actively detect the distance between the second earphone and the first earphone. In response to the distance between the second earphone and the first earphone being greater than a distance threshold, the second earphone may output a second distance prompt message and send a distance prompt instruction to the first earphone, so that the first earphone outputs a first prompt message based on the distance prompt instruction.

[0078] By implementing the embodiments of the present application, voice intercom can be directly and conveniently realized based on wireless earphones without relying on an electronic device, which is beneficial to improving the flexibility and convenience of voice intercom.

[0079] Figure 4 The illustrated embodiments describe the process of directly realizing voice intercom between two objects based on the two earphone bodies of one wireless earphone. In some embodiments, multiple wireless earphones (one wireless earphone may include two earphone bodies) may also establish a connection with an electronic device to realize voice intercom among more than two objects.

[0080] Exemplarily, taking the connection of two wireless earphones to an electronic device to realize voice intercom among four objects as an example, please refer to Figure 5 , Figure 5 which is another schematic diagram of an application scenario provided by the embodiments of the present application. In Figure 5Among them, the first earphone, the second earphone, the third earphone, and the fourth earphone can be respectively connected to the electronic device. Among them, the first earphone and the electronic device can establish a first sub-link, the second earphone and the electronic device can establish a second sub-link, the third earphone and the electronic device can establish a third sub-link, and the fourth earphone and the electronic device can establish a fourth sub-link.

[0081] In response to the first earphone intercom instruction, the first earphone can turn on the first microphone. The first earphone can collect the first voice data of the first object through the first microphone and send the first voice data to the electronic device based on the first sub-link. The electronic device can send the first voice data to the second earphone based on the second sub-link, send the first voice data to the third earphone based on the third sub-link, and send the first voice data to the fourth earphone based on the fourth sub-link.

[0082] In response to the second earphone intercom instruction, the second earphone can turn on the second microphone. The first earphone can collect the second voice data of the second object through the second microphone and send the second voice data to the electronic device based on the second sub-link. The electronic device can send the second voice data to the first earphone based on the first sub-link, send the second voice data to the third earphone based on the third sub-link, and send the second voice data to the fourth earphone based on the fourth sub-link.

[0083] In response to the third earphone intercom instruction, the third earphone can turn on the third microphone. The third earphone can collect the third voice data of the third object through the third microphone and send the third voice data to the electronic device based on the third sub-link. The electronic device can send the third voice data to the first earphone based on the first sub-link, send the second voice data to the second earphone based on the second sub-link, and send the third voice data to the fourth earphone based on the fourth sub-link.

[0084] In response to the fourth earphone intercom instruction, the fourth earphone can turn on the fourth microphone. The fourth earphone can collect the fourth voice data of the fourth object through the fourth microphone and send the fourth voice data to the electronic device based on the fourth sub-link. The electronic device can send the fourth voice data to the first earphone based on the first sub-link, send the fourth voice data to the second earphone based on the second sub-link, and send the fourth voice data to the third earphone based on the third sub-link.

[0085] In some embodiments, the first earphone and the second earphone may be wireless earphones belonging to the first earphone case, and the third earphone and the fourth earphone may be wireless earphones belonging to the second earphone case. The second earphone of the first earphone case can be placed in the first earphone case to be paired with the electronic device, and the third earphone and the fourth earphone can be placed in the second earphone case to be paired with the electronic device. Optionally, the first earphone case and the second earphone case can be paired with the electronic device based on Bluetooth. For example, after the electronic device turns on Bluetooth and the first earphone case approaches the electronic device, the pairing between the first earphone case and the electronic device can be achieved. Similarly, when the second earphone case approaches the electronic device, the pairing between the second earphone case and the electronic device can be achieved. When the first earphone case and the second earphone case approach the electronic device simultaneously, the electronic device can support one-key pairing with both earphone cases at the same time.

[0086] Exemplarily, please refer to Figure 6A , Figure 6A which is a schematic diagram of an interface for pairing an electronic device with an earphone case provided by an embodiment of the present application. As Figure 6A shown, pairing prompt information 601 can be displayed in the pairing interface 60 of the electronic device. The pairing prompt information 601 can be used to prompt whether to pair with the first earphone case and the second earphone case. Optionally, a confirmation option 602 and a cancellation option 603 can also be displayed in the pairing interface 60. In response to a trigger operation on the confirmation option 602, the electronic device can pair with the first earphone case and the second earphone case simultaneously.

[0087] After the electronic device successfully pairs with the first earphone case and the second earphone case, it can enter Figure 6B the pairing interface 61 shown. Pairing success prompt information 611 can be displayed in the pairing interface 61. The pairing success prompt information 611 can be used to prompt that the electronic device has successfully paired with the first earphone case and the second earphone case, that is, the electronic device has successfully established connections with the first earphone, the second earphone, the third earphone, and the fourth earphone. Optionally, the pairing success prompt information 611 can also be used to prompt whether to set the first earphone case and the second earphone case. A "Got it" option 612 and a "Go to settings" option 613 can also be displayed in the pairing interface 61. In response to a trigger operation on the "Go to settings" option 613, the electronic device can enter Figure 6C the settings interface shown.

[0088] Optionally, Figure 6C the settings interface 62 shown may include a settings option 621 for the first earphone case and a settings option 622 for the second earphone case. The functions of the first earphone and the second earphone in the first earphone case can be set through the settings option 621, and the functions of the third earphone and the fourth earphone in the second earphone case can be set through the settings option 622.

[0089] For example, in response to a trigger operation for setting option 621, the electronic device can enter Figure 6D the setting interface 63 as shown. Figure 6D The setting interface 63 as shown may include a traditional mode option 631 and a voice intercom mode option 632. Among them, in response to a trigger operation for the traditional mode option 631, the electronic device can control the first earphone and the second earphone to enter the traditional mode, that is, the first earphone and / or the second earphone can turn off the microphone. In this case, the first earphone and the second earphone can be worn by the same object (such as the first object), and the first object can listen to music or make and receive calls by wearing the first earphone and the second earphone. In response to a trigger operation for the voice intercom mode option 632, the electronic device can control the first earphone and the second earphone to enter the voice intercom mode, that is, the first earphone turns on the first microphone, and the second earphone turns on the second microphone. In this case, the first earphone and the second earphone can be worn by two different objects (such as the first object and the second object), and the first object wearing the first earphone can have a voice intercom with the second object wearing the second earphone.

[0090] In this way, after the electronic device is successfully paired with the first earphone case and the second earphone case, it can control the first earphone, the second earphone, the third earphone, and the fourth earphone to turn on the voice intercom function, and a voice intercom can be carried out among the first object wearing the first earphone, the second object wearing the second earphone, the third object wearing the third earphone, and the fourth object wearing the fourth earphone. For example, the first earphone can collect the first voice data of the first object, such as "Where are you?", and send the first voice data to the electronic device. The electronic device can send the first voice data to the second earphone, the third earphone, and the fourth earphone, and receive the second voice data from the second earphone, such as "Location A", receive the third voice data from the third earphone, such as "Location B", and the fourth voice data from the fourth earphone, such as "Location C". The electronic device can send the second voice data, such as "Location A", to the first earphone, the third earphone, and the fourth earphone, send the third voice data, such as "Location B", to the first earphone, the second earphone, and the fourth earphone, and send the fourth voice data, such as "Location C", to the first earphone, the second earphone, and the third earphone. Optionally, the time when the electronic device receives the first voice data, the time when it receives the second voice data, the time when it receives the third voice data, and the time when it receives the fourth voice data can be the same.

[0091] In this way, voice intercom among more than two objects can be realized, which is beneficial to improving the flexibility and convenience of voice intercom.

[0092] Optionally, when the connection between the electronic device and the first earphone case and / or the second earphone case is disconnected, for example, when the electronic device has insufficient power or the distance between the electronic device and the earphone case is too far, causing the connection between the electronic device and the first earphone case and / or the second earphone case to be disconnected, the first earphone and the second earphone can re - establish a communication link to resume the voice intercom between the user wearing the first earphone and the user wearing the second earphone, and the third earphone and the fourth earphone can re - establish a communication link to resume the voice intercom between the user wearing the third earphone and the user wearing the fourth earphone. Optionally, the way for the first earphone and the second earphone to re - establish the communication link can be that the master earphone (such as the first earphone) sends a connection request to the slave earphone (such as the second earphone) when it detects that the connection with the electronic device is disconnected, and the slave earphone responds to this connection request and re - establishes a communication link with the master earphone. This is beneficial to improving the stability of voice intercom.
