The NPU is a neural-network (NN) computing processor that processes input information quickly by using a biological neural network structure, for example, by using a transfer mode between neurons of a human brain, and can also learn by itself continuously.

The external memory interface 120 may be used to connect an external memory card, such as a Micro SD card, to extend the storage capability of the smart terminal 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function. For example, files such as music, video, etc. are saved in an external memory card. The internal memory 121 may be used to store computer-executable program code, which includes instructions.

In some embodiments, the wireless communication module 203 may include a bluetooth chip, which may support the wireless headset 200 for bluetooth connections with multiple electronic devices. For example, the first wireless headset may pair with the smart terminal 100 through a bluetooth chip and establish a bluetooth connection, so as to implement wireless communication and audio service processing with the smart terminal 100 through the bluetooth connection. Meanwhile, the first wireless earphone can establish Bluetooth connection with the second wireless earphone through the Bluetooth chip so as to realize wireless communication and audio service processing before the second wireless earphone through the Bluetooth connection. The bluetooth chip may also support, for example, the audio broadcasting function in the LE audio core protocol specification, so that the wireless headset 200 may broadcast one or more audio streams to an unlimited number of audio receiver devices (such as other wireless headsets), thereby implementing audio sharing (audio sharing) among multiple bluetooth devices.

In addition, the wireless communication module 203 may further include an antenna. The wireless communication module 203 receives electromagnetic waves via an antenna, performs frequency modulation and filtering processing on electromagnetic wave signals, and transmits the processed signals to the processor 201. The wireless communication module 203 may also receive a signal to be transmitted from the processor 201, perform frequency modulation and amplification on the signal, and convert the signal into electromagnetic waves through the antenna to radiate the electromagnetic waves.

The wireless communication module 203 may acquire signals, such as a probe request, a scan signal, and the like, transmitted by other devices (such as the smart terminal 100), and may send a response signal, a scan response, and the like, so that the other devices (such as the smart terminal 100) may discover the wireless headset 200 and establish a wireless communication connection with the other devices (such as the smart terminal 100).

The wireless communication module 203 may also transmit a signal, such as a broadcast BLE signal, so that other devices (e.g., the smart terminal 100) may discover the wireless headset 200 and establish a wireless communication connection with other devices (e.g., the smart terminal 100) to communicate with other devices (e.g., the smart terminal 100) via bluetooth.

The audio module 204 may be used to manage audio data and enable the wireless headset 200 to input and output audio signals. For example, the audio module 204 may obtain an audio signal from the wireless communication module 203 or transfer the audio signal to the wireless communication module 203, so as to implement functions of making and receiving calls through a wireless headset, playing music, activating/deactivating a voice assistant of a smart terminal connected to the headset, receiving/transmitting voice data of a user, and the like.

In some embodiments, the power module 205 may also include a wireless charging coil for wirelessly charging the wireless headset 200. In addition, the power management unit can also be used for monitoring parameters such as battery capacity, battery cycle number, battery health state (electric leakage and impedance) and the like.

A plurality of input/output interfaces 206 (i.e., communication interfaces) may be used to provide a wired connection for charging or communication between the wireless headset 200 and the headset case. In some embodiments, the input/output interface may be a USB interface. In other embodiments, the input/output interface 206 may be an earphone electrical connector, and when the wireless earphone 200 is placed in an earphone box, the wireless earphone 200 may establish an electrical connection with the electrical connector in the earphone box through the earphone electrical connector, thereby charging a battery in the wireless earphone 200. In other embodiments, after the electrical connection is established, the wireless headset 200 may also be in data communication with a headset box, for example, may receive a pairing instruction from the headset box.

In addition, the wireless headset 200 may also include a sensor 207. For example, the sensor 207 may be a distance sensor or a proximity light sensor that may be used to determine whether the wireless headset 200 is worn by a user. For example, the wireless headset 200 may determine whether the wireless headset 200 is worn by the user by detecting whether there is an object near the wireless headset 200 using a distance sensor. Upon determining that the wireless headset 200 is worn, the wireless headset 200 may turn on the speaker.

As another example, the sensor 207 may also comprise a bone conduction sensor, integrated into a bone conduction headset. By using the bone conduction sensor, the wireless headset 200 can acquire the vibration signal of the vibration bone mass of the human body part, analyze the voice signal, realize the voice function, and receive the voice command of the user. The wireless headset 200 may also perform voice authentication according to the user voice signal acquired by the bone conduction headset, so as to authenticate the user identity in the service scenarios such as payment transaction.

The sensor 207 can convert the audio synchronization triggering operation into an electric signal to be transmitted to the processor 201, so that the processor 201 can determine which audio playing device to establish a wireless connection to share audio according to the audio synchronization triggering operation and the like.

It is to be understood that the illustrated structure of the embodiment of the present application does not constitute a specific limitation to the wireless headset 200. It may have more or fewer components than shown in fig. 3, may combine two or more components, or may have a different configuration of components. For example, the wireless headset 200 may further include a key 208, an indicator light (which may indicate the status of power, incoming/outgoing call, pairing mode, etc.), a display screen (which may prompt the user for relevant information), a dust screen (which may be used with an earphone), and other components on the outer surface. The key 208 may be a physical key or a virtual key (used in cooperation with the touch sensor), and is used to trigger operations such as power on, power off, pause, play, record, start pairing, audio sharing, and reset.

The various components shown in fig. 3 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing or application specific integrated circuits.

Illustratively, as shown in fig. 4, a bluetooth protocol framework provided for the embodiment of the present application includes, but is not limited to, a Host protocol stack, an hci (Host Controller interface), and a Controller (Controller).

The Host protocol stack defines a plurality of applications (profiles) and a core protocol (protocol) in a bluetooth framework, each profile defines a respective corresponding message format and application rule, and the profile is a bluetooth service (application). In order to implement interconnection and interworking of different devices on different platforms, the bluetooth protocol defines specifications for various possible and common application scenarios, such as A2DP (advance audio distribution profile), HFP (HFP-free profile), and the bluetooth low-power audio standard (LE audio) related to the embodiment of the present application. The core protocol includes, but is not limited to, a bluetooth basic service protocol (service discovery protocol), a logical link control and adaptation protocol (L2 CAP), and the like. The core protocol is essential in the bluetooth protocol stack.

The HCI provides a unified interface entering the link manager and a unified mode entering the baseband for the upper layer protocol, there will be several transmission layers between the host core protocol stack and the controller, these transmission layers are transparent and complete the task of transmitting data, and the bluetooth alliance (SIG) specifies four physical bus modes connected to hardware, that is, four HCI transmission layers: USB, RS232, UART and PC card.

The Controller defines the bottom hardware part, including Radio Frequency (RF), baseband (BB) and Link Management (LM), and the RF passes through the microwave of the ISM band that does not need authorization at 2.4GHz, realizes the filtration and transmission of data bit stream, and mainly defines the conditions that the bluetooth transceiver needs to satisfy in this frequency band for normal operation. The baseband is responsible for frequency hopping and transmission of blue color data and information frames. The link management is responsible for connecting, establishing and removing links and performing security control. The lm (link manager) layer is a link management layer protocol of the bluetooth protocol stack, and is responsible for translating an upper layer HCI command into an operation acceptable by a baseband, establishing an asynchronous link-oriented link (ACL) and a synchronous link-oriented/extended (SCO), and entering a bluetooth audio device into an operation mode in a power saving state, and the like. The lc (link control) layer is responsible for transmitting devices in a batch of packets in response to upper layer LM commands (e.g., LM commands that perform the functions of establishing a transmission link for packets, maintaining a link, etc.).

The method according to the embodiment of the present application may be implemented by the wireless communication module 160 of the smart terminal 100 shown in fig. 2 and the wireless communication module 203 of the wireless headset 200 shown in fig. 3, and may specifically be executed by bluetooth modules or bluetooth chips in the smart terminal 100 and the wireless headset 200.

In order to better understand the communication method for audio synchronization provided in the embodiment of the present application, the following takes the first wireless headset as a TWS bluetooth headset as an example, and introduces the operating characteristics of the wireless headset. Illustratively, as shown in fig. 5, a schematic diagram of a TWS bluetooth headset is shown.

The TWS bluetooth headset may include a headset body 200A (also called a left earpiece) and a headset body 200B (also called a right earpiece) that are respectively worn on the left ear and the right ear of the user. The wireless headset has a head-wearing type and an in-ear type, and the TWS Bluetooth headset in the embodiment of the application can be in-ear type. The TWS bluetooth headset body may include a housing and internal components, the internal components being disposed within a cavity formed by the housing, and the internal components may include devices in the above-described audio module, power module, wireless communication module, and the like.

Two earphones of the TWS Bluetooth earphone can be divided into a main earphone and a secondary earphone, and data transmission can be carried out between the main earphone and the secondary earphone based on a Bluetooth protocol. For example, the primary earpiece may transmit audio data to the secondary earpiece over a bluetooth link with the secondary earpiece. During the use process of the TWS Bluetooth headset, the primary and secondary roles of the two headsets can be switched. For example, the primary and secondary roles of the headset may be determined based on the headset power, e.g., the higher power headset may be the primary headset. For another example, a default setting may be set to have one earphone as the primary earphone and the other earphone as the secondary earphone. The embodiments of the present application do not limit this.

In some embodiments, the TWS bluetooth headset may establish a bluetooth connection with the smart terminal through the primary headset and exchange control information, audio service control information, and the like through a bluetooth link with the smart terminal. The connection control information can be used for establishing or disconnecting the TWS Bluetooth headset and the intelligent terminal; the audio service control information may be used, for example, for operations such as audio service operation control (e.g., pause, play, last, etc.).

In some embodiments, the TWS bluetooth headset may establish a connection with other bluetooth audio devices (e.g., a second wireless headset) while connected with the smart terminal. For example, the TWS bluetooth headset may obtain communication information of other bluetooth audio devices, such as media access control address (MAC), device identifier (e.g., device model, device name), and the like; and then, establishing connection with other audio playing equipment according to the communication information. The manner in which the TWS bluetooth headset obtains the communication information of other bluetooth audio devices (e.g., the second wireless headset) will be described below and will not be described in detail here.

It should be understood that the above description only uses the TWS bluetooth headset as an example to describe the interaction manner between the wireless headset and other devices (such as a smart terminal, a second wireless headset, etc.), but in practical applications, the wireless headset may also be other types of headsets, and the embodiments of the present application do not limit this.

It should be understood that the communication method for audio synchronization provided by the embodiment of the present application may be applied in a scenario where audio is synchronized among multiple sets of headphones. For example, taking the smart terminal as a mobile phone of the user a as an example, an application scenario to which the audio synchronization communication method provided by the embodiment of the present application may be applied is exemplarily described below.

The application scene one: scenario for user A to trigger audio synchronization between earphones at wireless earphone side

In one possible scenario, user a and user B each wear their respective wireless headset (e.g., corresponding to the first wireless headset and the second wireless headset, respectively) to listen to audio. In the process of listening to the audio, if the user a finds that a certain audio melody is good and wants to share the audio with the user B (or the user a receives an incoming call and wants to listen to the call audio together with the user B), the user a may perform an audio synchronization triggering operation corresponding to the second wireless headset on the first wireless headset worn by the user a (for example, the second wireless headset and the first wireless headset collide with each other), and instruct the first wireless headset of the user a to share the audio with the second wireless headset. For example, in this scenario, the user a and the user B may be lovers, and the first wireless headset and the second wireless headset may be described as lovers headsets, for example.

In another possible scenario, user a, user B, and user C each wear their respective wireless headset (e.g., first wireless headset, second wireless headset, and third wireless headset, respectively) to listen to audio. The first wireless earphone, the second wireless earphone and the third wireless earphone are matched with the mobile phone of the user A in advance through Bluetooth, and are matched devices of the mobile phone. Different wireless earphones correspond to different audio synchronous triggering operations respectively, wherein the audio synchronous triggering operation corresponding to the second wireless earphone is, for example, one touch, and the audio synchronous triggering operation corresponding to the third wireless earphone is, for example, two touches. In the process that the user A listens to the mobile phone audio through the first wireless earphone, if the user A wants to synchronously share the audio with the user B, the user A can execute the audio synchronous triggering operation corresponding to the second wireless earphone, and if the second wireless earphone and the first wireless earphone collide with each other, the first wireless earphone is indicated to share the audio with the second wireless earphone. In addition, if the user a wants to share the audio with the user C, the user a may also instruct the first wireless headset to share the audio with the third wireless headset synchronously by performing an audio synchronization triggering operation corresponding to the third wireless headset, for example, causing the first wireless headset and the third wireless headset to collide twice.

Application scenario two: scene that user A triggers audio sharing between earphones at mobile phone side

In one possible scenario, when a user a listens to audio through a first wireless headset worn by the user a, if the user a wants to synchronously share the audio with a user B, the user a may instruct the first wireless headset to synchronously share the audio with a second wireless headset worn by the user B through a specific application (e.g., a setting, a smart housekeeping App, etc.) on the mobile phone of the user a.

According to the audio synchronization communication method provided by the embodiment of the application, a user can accurately determine the earphone which wants to share the audio by executing the specific audio synchronization triggering operation or by the indication of the mobile phone, so that the effect of quickly and efficiently sharing the audio among multiple earphones is achieved.

It should be understood that, in the embodiment of the present application, multiple wireless headsets sharing audio may establish a bluetooth connection with the smart terminal in advance. In order to better understand the audio synchronization communication method provided in the embodiment of the present application, a bluetooth pairing process between a wireless headset and an intelligent terminal is described below.

For example, when the smart terminal is not paired with the wireless headset, after the bluetooth function is turned on, the smart terminal may send an inquiry request (inquiry request) to the surroundings. When the wireless headset is in an inquiry bluetooth scan (inquiry scan) state, the wireless headset may scan an inquiry request sent by the intelligent terminal. In response to the scanned inquiry request, the wireless headset may send an inquiry response (inquiry response) to the smart terminal, so that the smart terminal acquires the wireless headset as a mateable bluetooth device option. After the user selects the device option of the wireless headset, the intelligent terminal may send a paging request (page request) to the wireless headset. The wireless headset may monitor a paging request of the smart terminal at a fixed frequency modulation frequency within a fixed time window at fixed intervals, and after the paging request of the smart terminal is monitored, the wireless headset may transmit a slave paging response (slave page response) to the smart terminal in a next time slot. After receiving the slave paging response of the wireless headset, the intelligent terminal may send a master paging response (master paging response) to the wireless headset in the next time slot. And then, after the wireless earphone and the intelligent terminal finish pairing authentication, the Bluetooth connection for transmitting data can be established.

It should be understood that, in this embodiment of the application, a user may preset an audio synchronization triggering operation corresponding to different wireless headsets, where the audio synchronization triggering operation is used to trigger a source audio headset (for example, a first wireless headset currently having an audio playing service with an intelligent terminal) to share audio with other audio playing devices (for example, a second wireless headset) corresponding to the operation. Illustratively, a user can set audio synchronous trigger operations corresponding to different wireless headsets through the intelligent terminal. Taking the setting of the audio synchronization triggering operation corresponding to the second wireless headset as an example, the process may include: after the second wireless headset and the intelligent terminal are connected in a pairing manner, a user can set corresponding audio synchronous triggering operation on the intelligent terminal for the second wireless headset, and can send the audio synchronous triggering operation corresponding to the wireless headset to other paired wireless headsets (such as the first wireless headset). Subsequently, the audio synchronous triggering operation corresponding to the second wireless earphone can be input into the first wireless earphone, so that the first wireless earphone can share the audio with the second wireless earphone.

In some embodiments, a user may determine whether to set an audio synchronization trigger operation for a wireless headset that completes a pairing connection according to actual requirements for sharing audio. For example, a user a usually plays audio of an intelligent terminal by using a first wireless earphone worn by the user a, and in the process of playing the audio, the user B often shares the audio with a second wireless earphone worn by the user B, so that in order to make the process of synchronizing the audio between the first wireless earphone and the second wireless earphone more convenient and efficient, the user a may set an audio synchronization triggering operation (for example, a touch operation) corresponding to the second wireless earphone in advance through the intelligent terminal, so that when subsequently sharing the audio, the first wireless earphone and the second wireless earphone touch one another.

In order to better understand the audio synchronization communication method provided in the embodiment of the present application, a process in which a user sets an audio synchronization trigger operation corresponding to a second wireless headset through an intelligent terminal is described in more detail below with reference to a Graphical User Interface (GUI) of the intelligent terminal. Illustratively, as shown in fig. 6A to 6E, some GUI diagrams provided for the embodiments of the present application are provided. Here, the intelligent terminal is a mobile phone as an example.

Illustratively, as shown in fig. 6A, it is a schematic diagram of a home screen interface of a mobile phone. The home screen interface may include an application icon display area 10 for displaying various types of application icons, such as a clock icon, a calendar icon, a gallery icon, a memo icon, a file management icon, an e-mail icon, a music icon, a calculator icon, a recorder icon, an exercise health icon, a weather icon, a browser icon, a wisdom housekeeping icon, a setting icon, and the like. Beneath the plurality of application icons may be a page indicator display area 20 that includes a page indicator to indicate the positional relationship of the currently displayed page to other pages. A tray application icon display area 30 may be displayed below the page indicator for displaying a plurality of tray application icons, such as a camera application icon, a directory application icon, a phone dialing application icon, an information application icon, and the like. In other embodiments, the cell phone home screen interface may include more or fewer application icons or tray application icons than those shown, which are not limited in this application. A status bar 40 may also be displayed above the interface, and the status bar 40 may include: one or more signal strength indicators for mobile communication signals (or cellular signals), one or more signal strength indicators for wireless fidelity (Wi-Fi) signals, a battery level indicator for a handset, a time indicator, etc.

In some embodiments, the handset may receive a click operation of the user a for setting the application icon 101. In response to the click operation of the user a, the mobile phone may display a setting application interface as shown in fig. 6B.

As shown in fig. 6B, the settings interface may include multiple service types, such as wireless and network services, bluetooth services, desktop and wallpaper services, display services, sound services, application services, battery services, storage services, health usage handset services, security and privacy services, and the like. In other embodiments, the setting interface may include more or less types of services than those shown, which is not limited in this application. In some embodiments, the mobile phone may receive a click operation of the user a for the bluetooth service, and in response to the click operation of the user a, the mobile phone may display a bluetooth setting interface as shown in fig. 6C.

As shown in fig. 6C, the bluetooth setting interface may include a switch control corresponding to the bluetooth function, and when the bluetooth function is in an on state, prompt information such as "currently discoverable by nearby bluetooth devices" may be displayed below the bluetooth function. The device name of the mobile phone (e.g. horor 8X shown in fig. 6C) can be displayed below the bluetooth function, a next page indicator can be displayed behind the device name, and by clicking the next page indicator, the mobile phone can display a device name modification page (not shown in the figure) for the user to modify the device name of the mobile phone. A file receiving management column can be displayed below the device name, and a user can manage files received by the mobile phone through Bluetooth by receiving a next page indicator in the file receiving management column. In addition, the bluetooth setup interface may further include a paired device list, for example, including a first wireless headset, a second wireless headset, and a third wireless headset, where a setup control is corresponding to a rear of each paired device.

In some embodiments, the mobile phone may receive a click operation of the user a on a setting control of the paired second wireless headset, and in response to the click operation, the mobile phone may display a paired bluetooth device management interface as shown in fig. 6D.

As illustrated in fig. 6D, the paired bluetooth device management interface may include a rename bar for the bluetooth device through which the user may modify the name of the second wireless headset. The paired bluetooth device management interface may further include a plurality of configuration item management fields, such as a call audio management field, a media audio management field, a shared contact management field, and an audio synchronization trigger operation management field. The user can start or close the call audio service between the second wireless earphone and the mobile phone by clicking a switch control in the call audio management bar; the user can start or close the media audio service between the second wireless earphone and the mobile phone by clicking the switch control in the media audio management bar; the user can also start or close the function of sharing the contact information between the second wireless earphone and the mobile phone by clicking the switch control in the shared contact management bar. For example, an audio synchronization triggering operation management column in the bluetooth device management interface may display description information of the audio synchronization triggering operation, such as "connection triggering operation may be performed on other devices, so as to implement fast connection between other bluetooth devices and the second wireless headset". The management bar may also display a next page indicator 102, and when the user clicks the next page indicator 102, the handset may display an audio synchronization triggering operation management interface as shown in fig. 6E.

As shown in fig. 6E, the connection trigger operation management interface may include a plurality of audio synchronous trigger operation options, such as touch-on-touch, single-touch, touch-on-touch, slide from bottom to top, slide from top to bottom, and the like. The user can set the audio sharing triggering operation corresponding to the second wireless earphone by clicking a corresponding selection control after a certain audio synchronization triggering operation. For example, the user may click and select the option box after "hit-and-miss" and set the audio sharing trigger operation corresponding to the second wireless headset to hit-and-miss. The subsequent user can touch the wireless earphone (such as the first wireless earphone) of the subsequent user through the second wireless earphone, so that the audio can be shared by the first wireless earphone to the second wireless earphone.

It should be understood that when the audio synchronization triggering operation corresponding to the second wireless headset is collision, the audio synchronization triggering operations corresponding to other wireless headsets (such as the third wireless headset) paired with the mobile phone cannot be set to collision. For example, the touch-and-click option may not be displayed in the audio synchronization triggering operation interface corresponding to the third wireless headset, so as to avoid user's misselection, and thus the bluetooth device that needs to share audio quickly cannot be identified according to a specific operation.

The manner of setting the connection triggering operation corresponding to the bluetooth device in the manner shown in fig. 6A to fig. 6E is only an example, and in practical applications, the setting is not limited to the setting by setting an application program, and is not limited to the several audio synchronous triggering operations described above, and any manner capable of setting the connection triggering operation corresponding to the bluetooth device is within the protection scope of the embodiment of the present application.

The following describes an exemplary process of triggering audio sharing among multiple sets of earphones by a user on a mobile phone side, with reference to the accompanying drawings. This process may correspond to scenario two above. Fig. 7A to 7E are schematic diagrams of some Graphical User Interfaces (GUIs) provided in the embodiments of the present application. Here, the example that the smart terminal is the mobile phone of the user a is still described.

In one possible scenario, the user a may initiate the audio sharing function of the first wireless headset through an application on the handset in advance. For example, the function of the first wireless headset sharing audio may refer to a function of the first wireless headset directly sharing audio played by the first wireless headset to the second wireless headset without sending audio to the second wireless headset by the mobile phone.

Illustratively, as shown in fig. 7A, it is a schematic diagram of a home screen interface of a mobile phone. The mobile phone home screen interface is similar to that in fig. 6A, and the related descriptions can be referred to the above related contents, which are not described herein again.

In some embodiments, the cell phone may receive a click operation of user a on the smart housekeeping application icon 103. In response to the click operation of the user a, the mobile phone may display an intelligent housekeeping application interface as shown in fig. 7B.

As shown in fig. 7B, the smart housekeeping application interface may include the name of the smart housekeeping system and the devices and members included in the smart housekeeping system, for example, the name of the smart housekeeping system in which the user a is located is "my home", and the smart housekeeping system includes 3 members and 12 devices. For example, the intelligent housekeeping application interface may further display a device management area, which may include different types of device icons, such as bluetooth devices, home devices, and travel devices. The bluetooth device may include, for example, a device supporting a bluetooth function, such as a wireless headset and a bluetooth speaker; the household equipment can comprise equipment such as an intelligent door lock, an intelligent air conditioner and the like; the travel device may include, for example, an in-vehicle device or the like. It should be understood that some household devices and trip devices may also have a bluetooth function, that is, some devices may belong to both the household devices or the trip devices and the bluetooth devices, which is not limited in this embodiment of the present application. Illustratively, a member management area may be further displayed below the device management area, and the member management area may include icons corresponding to members (such as user a, user B, and user C) in the smart housekeeping system. In addition, the bottom of the intelligent housekeeper application management interface can also display icons of different pages of the intelligent housekeeper, such as a home icon, a mall icon, an intelligent icon, a my icon and the like.

In some embodiments, the members included in the smart housekeeper (e.g., user a, user B, and user C displayed in the member management area) may be registered with the smart housekeeper App in advance. Each device included in the smart housekeeper can be registered with device information in advance by a user through the smart housekeeper App, or after each device can be connected with the mobile phone (such as Bluetooth pairing connection), the mobile phone automatically updates the device information to the smart housekeeper system. This is not a limitation of the present application.

In some embodiments, as shown in fig. 7B, the handset may receive a click operation of user a on the smart housekeeping application interface with respect to the bluetooth device icon. In response to the click operation by the user, the mobile phone may display a bluetooth device management interface as shown in fig. 7C.

Illustratively, as shown in fig. 7C, a schematic diagram of a bluetooth device management interface is shown. The bluetooth device management interface may include bluetooth devices that the mobile phone has currently paired, including, for example, a first wireless headset worn by user a, a second wireless headset worn by user a, and a third wireless headset worn by user C. The bluetooth device management interface may further include a bluetooth device that is not currently paired with the mobile phone, for example, a bluetooth speaker, a tablet computer, a smart television, a smart watch, and the like. The bluetooth device management interface may further display the currently connected bluetooth device of the mobile phone and the audio service being executed by the bluetooth device, for example, in the currently connected bluetooth device area, it may be displayed that the currently connected bluetooth device of the mobile phone is the first wireless headset, and the audio service being executed by the first wireless headset is "currently playing audio in media". In addition, a next page indicator 104 may also be included in the currently connected bluetooth device management bar. When the handset receives a user's click operation for the next page indicator 104, a management interface of the first wireless headset as shown in fig. 7D may be displayed.

Illustratively, as shown in fig. 7D, a schematic diagram of a first wireless headset management interface is shown. The management interface of the first wireless headset may include, for example, a list of bluetooth devices that may currently establish a connection with the first wireless headset, including, for example, a second wireless headset and a third wireless headset. The second wireless earphone and the third wireless earphone are respectively and correspondingly provided with a connection control part which is connected with the first wireless earphone. The connection control may display the current connection status of the second wireless headset and the third wireless headset to the first wireless headset, respectively. For example, as shown in fig. 7D, the connection controls behind the second wireless headset and the third wireless headset are both currently not connected, which indicates that the second wireless headset and the third wireless headset are both currently in a state of not being connected to the first wireless headset.

In some embodiments, the cell phone may receive a click operation of the user a on a connection control corresponding to the second wireless headset. In response to the click operation of the user a, the mobile phone may instruct the first wireless headset to establish a bluetooth connection with the second wireless headset. In one implementation, in response to the click operation of the user a, the mobile phone may send communication information (such as a MAC address and a device identifier of the second wireless headset) of the second wireless headset to the first wireless headset; and the first wireless earphone establishes Bluetooth connection with the second wireless earphone according to the communication information of the second wireless earphone. After the first wireless headset and the second wireless headset establish the bluetooth connection, the connection control corresponding to the second wireless headset may be displayed as connected, which indicates that the first wireless headset is currently in a connection state with the second wireless headset. In one implementation, as shown in fig. 7E, the first wireless headset management interface may also display a prompt message to prompt the user that the first wireless headset and the second wireless headset have established a bluetooth connection. In one implementation, the prompt message of the first wireless headset management interface may also query the user whether to instruct the first wireless headset to share the currently played audio with the second wireless headset.

In some embodiments, the mobile phone may receive a confirmation operation of the user for sharing the audio, for example, clicking "yes" operation. In response to the confirmation operation of the user, the mobile phone may instruct the first wireless headset to share the audio with the second wireless headset. The way in which the first wireless headset shares audio with the second wireless headset will be described below, and will not be described in detail here.

It should be understood that the manner of audio synchronization shown in fig. 7A to 7E is merely an example, and in practical applications, a user may also instruct, in other manners, the wireless headset to share audio with other wireless headsets in other application programs, which is not limited in this embodiment of the application.

According to the communication method for audio synchronization, audio synchronization is directly performed between the wireless earphones, convenience of audio sharing between users can be improved, and use experience of the users is improved. Especially, under the scene that the user wears the earphones, the rapid and efficient audio synchronization can be realized on the basis that the user wears the earphones is not influenced.

The above embodiments describe the communication method for audio synchronization provided by the embodiments of the present application from an application scenario and a visual interface that may be involved in audio synchronization. In order to better understand the audio synchronization communication method provided in the embodiment of the present application, an internal implementation process of the method is described below.

Illustratively, as shown in fig. 8, a schematic flowchart of a communication method for audio synchronization provided by an embodiment of the present application is shown. For convenience of understanding, the present embodiment will be described by taking the wireless headsets as the first wireless headset and the second wireless headset, respectively. In the embodiment of the application, the wireless earphone for audio synchronization can complete Bluetooth pairing connection with the intelligent terminal in advance. For ease of understanding, the following describes the implementation of the audio-synchronized communication method in two stages.

Stage one: interaction stage of wireless earphone and intelligent terminal respectively

Illustratively, this stage one may specifically include the following steps:

s801, the intelligent terminal initiates Bluetooth pairing to the first wireless earphone.

In some embodiments, the smart terminal may establish a first communication link with the first wireless headset via bluetooth.

S802, the intelligent terminal initiates Bluetooth pairing to the second wireless earphone.

It can be understood that the above steps S801 and S802 take the smart terminal actively initiating the bluetooth pairing connection to the first wireless headset or the second wireless headset, respectively, as an example. However, in practical application, the bluetooth pairing process may also be actively initiated to the smart terminal by the first wireless headset and the second wireless headset, which is not limited in this embodiment of the present application.

In step S801, the process of bluetooth pairing between the intelligent terminal and the first wireless headset and the process of bluetooth pairing between the intelligent terminal and the second wireless headset in step S802 may refer to the above related contents about bluetooth pairing between the wireless headset and the intelligent terminal, and for avoiding repetition, details are not repeated here.

And S803, the intelligent terminal stores the communication information of the first wireless earphone and the second wireless earphone.

Wherein, the communication information of the bluetooth device may include: a connection address (e.g., MAC address) of the wireless headset, a device identification (e.g., device name, device model, etc.) of the wireless headset. The communication information is used to establish a connection with another device, such as a bluetooth connection.

In some embodiments, during the bluetooth pairing between the smart terminal and the first wireless headset, the communication information of the first wireless headset may be acquired and stored in the local storage space. Similarly, in the process of bluetooth pairing between the intelligent terminal and the second wireless headset, the communication information of the second wireless headset can be acquired, and the communication information of the second wireless headset is stored in the local storage space.

It should be understood that the specific order in which the intelligent terminal stores the communication information of the first wireless headset in step S803 is not limited in the embodiment of the present application. For example, the process of acquiring and storing the communication information of the first wireless headset by the smart terminal may also occur during the process of establishing the bluetooth pairing between the first wireless headset and the smart terminal, that is, concurrently with step S801 or after step S801. Similarly, the specific order in which the intelligent terminal stores the communication information of the second wireless headset in step S803 is not limited in this embodiment of the application. For example, the process of acquiring and storing the communication information of the second wireless headset by the smart terminal may also occur during the process of establishing the bluetooth pairing between the second wireless headset and the smart terminal, that is, concurrently with step S802 or after step S802.

It should be understood that after the intelligent terminal is paired with the first wireless earphone and the second wireless earphone through bluetooth, the communication information of the first wireless earphone and the second wireless earphone is acquired, so that when connection needs to be established between subsequent wireless earphones, the communication information of an opposite terminal is provided for the wireless earphones.

S804, the intelligent terminal sends the communication information of the second wireless earphone to the first wireless earphone.

In some embodiments, the smart terminal may send communication information of the second wireless headset to the first wireless headset over a first communication link with the first wireless headset.

Specifically, the intelligent terminal may send the communication information of the second wireless headset to the first wireless headset when a preset condition is satisfied. For example, when a first wireless headset is in a connected state with a smart terminal, the smart terminal may send communication information of a second wireless headset to the first wireless headset. For example, the process of the smart terminal sending the communication information of the second wireless headset to the first wireless headset may include: after the intelligent terminal and the first wireless earphone are paired in a Bluetooth mode, a first communication link is formed between the intelligent terminal and the first wireless earphone; and then, the intelligent terminal can send the acquired communication information of the second wireless earphone to the first wireless earphone through the first communication link. Alternatively, the smart terminal may send the acquired communication information of the second wireless headset to the first wireless headset through the first communication link when detecting that the first wireless headset performs an audio service (e.g., plays audio of the smart terminal). And or the intelligent terminal and the first wireless earphone finish Bluetooth pairing and the connection duration is longer than the first duration, and the acquired communication information of the second wireless earphone is sent to the first wireless earphone through the first communication link.

In other embodiments, step S804 may also be performed after the user indicates that the first wireless headset is connected to the second wireless headset, that is, step S804 may be performed after step S806.

It should be understood that the above-mentioned case that the intelligent terminal sends the communication information of the second wireless headset to the first wireless headset is only an example, and in practical applications, the intelligent terminal may also send the communication information of the second wireless headset to the first wireless headset in other cases, such as sending the communication information of the second wireless headset to the first wireless headset when the preset time is reached, and the application is not limited thereto.

Optionally, the first phase may further include step S805, that is, the smart terminal sends the communication information of the first wireless headset to the second wireless headset.

In some embodiments, if the second wireless headset is in a connected state with the smart terminal, the smart terminal may also send the communication information of the first wireless headset to the second wireless headset for the second wireless headset to actively initiate connection with the first wireless headset. The situation that the intelligent terminal sends the first wireless headset communication information to the second wireless headset is similar to the situation introduced in step S804, and reference may be made to the description of the related contents, which is not repeated herein.

And a second stage: interaction phase between wireless headsets

Illustratively, the stage two may specifically include the following steps:

s806, the first wireless earphone receives an audio synchronization trigger operation input by a user, and the audio synchronization trigger operation is used for instructing the first wireless earphone to synchronize audio to the second wireless earphone.

The audio synchronization triggering operation input by the user may be an audio synchronization triggering operation corresponding to the second wireless headset, and includes, for example: the user touches the first wireless earphone through the second wireless earphone; alternatively, the user taps a preset number of times (e.g., one tap) on the primary earpiece of the first wireless earpiece. Different audio synchronous triggering operations can be preset in different wireless earphones, if the second wireless earphone touches or taps once corresponding to the audio synchronous triggering operation, namely when a user touches or taps once the first wireless earphone on the first wireless earphone with the second wireless earphone, or taps once on the first wireless earphone, the wireless earphone indicates that the first wireless earphone synchronizes audio to the second wireless earphone.

Illustratively, a user can preset audio synchronous triggering operations corresponding to different wireless earphones through the intelligent terminal. For example, after the intelligent terminal and a certain bluetooth audio device complete pairing connection, the user may set an audio synchronization triggering operation corresponding to the bluetooth audio device through an application program in the intelligent terminal, and the process may correspond to the process shown in fig. 7A to 7E, for example.

In some embodiments, after the intelligent terminal obtains the audio synchronization triggering operation corresponding to the paired bluetooth audio device, the intelligent terminal may store the corresponding relationship between the bluetooth audio device and the audio synchronization triggering operation in a local location (e.g., a memory of the intelligent terminal). For example, the correspondence between different bluetooth audio devices and corresponding audio synchronization triggering operations may be as shown in table 1:

TABLE 1

Numbering	Bluetooth audio equipment	Audio synchronized trigger operation
			1	First wireless earphone	Is knocked once
2	Second wireless earphone	Knocking twice
			3	Third wireless earphone	Three times of knocking
…	…	…

It should be understood that the bluetooth audio device and the audio synchronization triggering operation corresponding to each bluetooth audio device shown in table 1 are only examples, and in practical applications, the bluetooth audio device may also be of other types or names, and the audio synchronization triggering operation may also be of other forms, which is not limited in this embodiment of the application.

S807, the first wireless headset synchronizes audio data to the second wireless headset.

In some embodiments, the first wireless headset may acquire an audio synchronization trigger operation corresponding to the second wireless headset in advance. The acquisition process may include, for example, the following ways:

in the method 1, if the intelligent terminal is already in a connection state with the first wireless headset, after the intelligent terminal acquires the audio synchronous triggering operation set by the user for the second wireless headset, the audio synchronous triggering operation corresponding to the second wireless headset can be sent to the first wireless headset through the first communication link with the first wireless headset.

In the mode 2, if the intelligent terminal is not connected to the first wireless headset, after the intelligent terminal obtains the audio synchronous triggering operation set by the user for the second wireless headset, the audio synchronous triggering operation corresponding to the second wireless headset is stored locally (for example, in the memory of the intelligent terminal); after the connection between the subsequent intelligent terminal and the first wireless earphone is established, the audio synchronous triggering operation corresponding to the second wireless earphone can be sent to the first wireless earphone.

In mode 3, when the first wireless headset receives an audio synchronization triggering operation input by a user, the first wireless headset may query the intelligent terminal for a bluetooth audio device corresponding to the audio synchronization triggering operation in response to the audio synchronization triggering operation. For example, the first wireless headset may send a query message to the intelligent terminal, where the query message may carry indication information of an audio synchronization triggering operation; after receiving the query message, the intelligent terminal queries corresponding Bluetooth audio equipment according to the indication information of the audio synchronous triggering operation in the query message; the smart terminal may then send a feedback message to the first wireless headset over the first communication link with the first wireless headset for the inquiry message, indicating the bluetooth audio device (e.g., the second wireless headset) to which the first operation corresponds.

In some embodiments, the first wireless headset may synchronize audio to the second wireless headset in response to an audio synchronization trigger operation of the user. For example, the manner in which the first wireless headset synchronizes audio to the second wireless headset may include:

in mode 1, the first wireless headset responds to the audio synchronization triggering operation input by the user, and determines that the bluetooth audio device corresponding to the audio synchronization triggering operation is the second wireless headset. The first wireless earphone initiates communication connection (such as Bluetooth connection) to the second Bluetooth device according to the pre-acquired communication information of the second wireless earphone, and establishes a second communication link. And then, the first wireless earphone forwards the audio data to the second wireless earphone through the second communication link, so that the second wireless earphone synchronously plays the audio.

Specifically, the first wireless headset may transmit a connection request message to the second wireless headset according to communication information of the second wireless headset. And after receiving the connection request message sent by the first wireless earphone, the second wireless earphone responds to the connection request message and establishes connection with the first wireless earphone. The process of establishing the bluetooth connection between the first wireless headset and the second wireless headset may refer to the above description of the bluetooth pairing connection, and is not described herein again.

In some embodiments, after the second wireless headset and the first wireless headset complete the bluetooth connection, the second wireless headset may send a connection completion notification to the first wireless headset so that the first wireless headset knows that the connection between the first wireless headset and the second wireless headset is established.

Optionally, the first wireless headset may send a connection completion notification to the smart terminal. The connection completion notification is sent to the intelligent terminal if the first wireless headset is over a first communication link between the first wireless headset and the intelligent terminal. After the intelligent terminal obtains the connection completion notification, the user may be prompted that the first wireless headset and the second wireless headset have established a connection, for example, by a prompt message as shown in fig. 7E. Optionally, the intelligent terminal may further prompt the user whether to instruct the first wireless headset to share the audio with the second wireless headset, so as to implement audio synchronization between the two pairs of wireless headsets, where the prompt information may be as shown in fig. 7E. In some embodiments, after the user inputs an operation indicating that the first wireless headset shares audio with the second wireless headset to the intelligent terminal, the intelligent terminal may send an indication message to the first wireless headset to indicate the first wireless headset to send audio data to the second wireless headset, so that the second wireless headset plays audio synchronously.

In some embodiments, the first wireless headset may also transmit audio data to the second wireless headset after receiving the connection completion notification in response to the connection completion notification. Specifically, the manner in which the first wireless headset transmits audio data to the second wireless headset may include the following manner:

mode 1, the first wireless headset sends audio data to the second wireless headset through the second communication link, and the second wireless headset can play audio synchronously based on the audio data.

It should be appreciated that the first wireless headset may synchronize audio, such as sending audio data or an audio broadcast message, etc., to the second wireless headset via the main earpiece. The second wireless headset may receive audio data or audio broadcast messages through the primary earpiece and forward the audio data to the secondary earpiece over a communication link with the secondary earpiece, thereby enabling both earpieces of the second wireless headset to play audio simultaneously.

Alternatively, in other embodiments, if the user inputs an operation confirming that the audio is synchronized by the first wireless headset to the second wireless headset through the smart terminal in step S806, and the smart terminal sends an instruction message for forwarding the audio to the first wireless headset, the first wireless headset may send the audio data to the second wireless headset through the second communication link between the first wireless headset and the second wireless headset in response to the instruction message sent by the smart terminal, so as to complete the audio sharing with the second wireless headset. In one embodiment, the first wireless headset and the second wireless headset may each establish a bluetooth connection through respective master headsets and synchronize audio data. The determining mode of the main earphone of the wireless earphone can be flexibly set, for example: and determining the earphone with higher electric quantity as a main earphone and the like, wherein the main and auxiliary roles of the wireless earphone can be switched in the using process. The master earphone can synchronize the acquired communication information of other Bluetooth audio devices and the information such as audio synchronization triggering operation corresponding to other Bluetooth audio devices to the auxiliary earphone.

Mode 2, the first wireless headset responds to a first operation input by a user, and determines that the bluetooth device corresponding to the first operation is a second wireless headset. The first wireless earphone sends an audio broadcast message, wherein the audio broadcast message comprises audio data and carries identification information corresponding to the second wireless earphone, and the identification information is used for indicating that the second wireless earphone plays audio synchronously. And after the second wireless earphone receives the audio broadcast message comprising the audio data, analyzing and acquiring the audio data based on the identification information, and further realizing synchronous audio playing.

The identification information carried by the broadcast message may be flexibly set in advance, such as a name of the device to be used for sharing the audio, a model of the device, and the like.

And S808, synchronously playing the audio by the second wireless earphone.

In some embodiments, after receiving the audio data forwarded by the first wireless headset, the second wireless headset may play audio through a speaker, so as to play audio synchronously with the first wireless headset. Specifically, if the main earphone of the second wireless earphone receives the audio forwarded by the first wireless earphone, after acquiring the audio data, the main earphone of the second wireless earphone can resynchronize the audio data to the auxiliary earphone of the second wireless earphone through a communication link between the main earphone and the auxiliary earphone, so that both earphones of the second wireless earphone can play the audio synchronously.

Illustratively, as shown in fig. 9, a schematic flowchart of a communication method for audio synchronization provided in an embodiment of the present application is shown. The schematic flow may correspond to the second scenario, that is, when there are more than two pairs of wireless earphones, the wireless earphone currently playing the audio of the intelligent terminal shares the audio with one pair of wireless earphones. For convenience of understanding, the multiple pairs of wireless earphones are respectively a first wireless earphone, a second wireless earphone and a third wireless earphone, which are taken as examples, where the first wireless earphone may be a wireless earphone currently performing an audio playing service of the intelligent terminal, and the second wireless earphone may be an earphone to be audio shared.

In order to better understand the audio synchronization communication method provided by the embodiment of the present application, the embodiment of the present application divides the implementation process of the method into two stages: the first stage, the interaction stage of the wireless earphone and the intelligent terminal; and a second stage, namely an interaction stage between the wireless earphones. The following is a description of the specific procedures of the two stages, respectively.

And S903, the third wireless earphone is paired with the intelligent terminal Bluetooth.

S904, the intelligent terminal stores the communication information of the first wireless earphone, the second wireless earphone and the third wireless earphone.

S905, the intelligent terminal sends the communication information of the second wireless earphone to the first wireless earphone.

The process of steps S901 to S905 is similar to that of steps S801 to S805, except that in the embodiment of fig. 9, there may be two (or more) wireless earphones (such as a second wireless earphone and a third wireless earphone) satisfying audio sharing around the first wireless earphone.

The intelligent terminal can share the communication information of other paired devices with the paired wireless earphones. Optionally, the intelligent terminal may further send communication information of a third wireless headset to the first wireless headset, may also send communication information of the first wireless headset and/or the third wireless headset to the second wireless headset, and may also send communication information of the first wireless headset and/or the second wireless headset to the third wireless headset.

Illustratively, the stage two may specifically include the following steps:

and S906, the first wireless earphone receives an audio synchronization trigger operation input by a user, and the audio synchronization trigger operation is used for instructing the first wireless earphone to synchronize audio to the second wireless earphone.
