Headset connection system, method, headset, electronic device, and readable storage medium

The present application is a divisional application of a chinese patent application filed on day 23 and month 08 of 2022, with application number 202211012343.0, application name "earphone connection system, method, earphone, electronic device, and readable storage medium".

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to an earphone connection system, an earphone connection method, an electronic device, and a readable storage medium.

Background

At present, a wireless earphone can be connected with other electronic devices through a wireless communication component such as Bluetooth and the like, a wireless communication channel is established, and data transmission such as audio is achieved.

However, when a headset that can establish a wireless communication connection with two or more other electronic devices is connected back to the other electronic devices, the state of the other electronic devices does not conform to the connection expectation, and thus the time for the connection is too long.

Disclosure of Invention

The application provides an earphone connection system, an earphone connection method, an earphone, electronic equipment and a readable storage medium, and solves the problem that the state of other electronic equipment is not in line with expectations, so that the reconnection time is too long.

In order to achieve the above purpose, the present application adopts the following technical scheme:

in a first aspect, a headset connection system is provided, which may include a headset and a first electronic device;

the first electronic device is used for sending out a first target broadcast signal at a first broadcast frequency after being disconnected with the earphone; and the earphone is used for scanning the first target broadcast signal at a first scanning frequency in a closed box state, and sending a communication connection signal to the first electronic equipment based on the scanned first target broadcast signal when the box is opened, so as to establish communication connection with the first electronic equipment.

For example, for a headset capable of establishing communication connection with a plurality of devices, such as a dual-connection headset, when only one electronic device is ready to be connected back to the headset, the headset can determine the in-place and connectable electronic device by scanning a target broadcast signal sent by the electronic device when the connection is disconnected, and can send a communication connection signal to the in-place and target broadcast signal-sending electronic device in time after the box is opened so as to quickly establish communication connection; and all the devices in the history connection information are sequentially connected and judged according to the history connection sequence without a connection record based on the history, so that the reconnection time of the earphone is greatly saved; meanwhile, when the earphone scans that one electronic device is in place, communication connection is only established with the electronic device, and the fact that all connected electronic devices are connected again after the earphone is opened for each time is not needed; the earphone connecting time is saved, and meanwhile, the earphone which establishes connection can quickly enter the operation state.

By the mode, when the earphone is opened, the communication connection signal can be rapidly sent to the first electronic equipment based on the first target broadcast signal scanned in the closed box state, and communication connection with the electronic equipment is initiated; therefore, the connectable electronic equipment conforming to the connection state is determined in advance in the closed box state, the time consumption of connection is caused because the connection judgment is not required to be initiated on the electronic equipment in an uncertain state based on the history connection information, and the speed of connecting the earphone with the electronic equipment in a back mode is improved; has stronger usability and practicability.

In a possible implementation manner of the first aspect, the system further includes a second electronic device; the second electronic device is used for sending out a second target broadcast signal at a second broadcast frequency after being disconnected with the earphone; the earphone is further used for scanning the second target broadcast signal at a first scanning frequency in a box closing state, and sending a communication connection signal to the first electronic device based on the scanned first target broadcast signal or sending a communication connection signal to the second electronic device based on the scanned second target broadcast signal when the box is opened, so that communication connection is respectively established with the first electronic device or the second electronic device.

For example, when two electronic devices in a to-be-connected state exist near the earphone and both send out a target broadcast signal of bluetooth low energy, the earphone may determine the connection sequence of the to-be-connected devices based on the frequency or sequence of the scanned target broadcast signals; or when the earphone is opened, determining the electronic equipment which preferentially establishes connection based on the target broadcast signal scanned for the first time. Therefore, the loop connection is not required to be verified in sequence based on the fixed connection sequence every time, and the efficiency of the earphone loop connection is improved.

In a possible implementation manner of the first aspect, the first electronic device is further configured to send out a first target broadcast signal including a first encryption protocol at a first broadcast frequency after being disconnected from the earphone; and the earphone is also used for sending a communication connection signal to the first electronic equipment based on the first encryption protocol in the scanned first target broadcast signal when the box is opened, and establishing communication connection with the first electronic equipment.

For example, the encryption protocol may agree on known protocol content for the headset and the electronic device, and the encryption protocol may be agreed upon and generated when the headset first establishes a connection with the electronic device.

Therefore, in a state that the earphone is disconnected from the electronic equipment, the electronic equipment to be connected can be determined to be positioned in a connectable range by scanning a target broadcast signal containing an encryption protocol, and when the earphone is opened, the electronic equipment immediately responds and establishes a reconnection with the determined electronic equipment based on the scanned target broadcast signal.

The first electronic device or the second electronic device is used for sending out a first target broadcast signal or a second target broadcast signal containing an encryption protocol after being disconnected with the earphone; the earphone is further used for determining that the device to be connected is the first electronic device or the second electronic device based on an encryption protocol in the first target broadcast signal or the second target broadcast signal; and when the box is opened, a communication connection signal is sent to the first electronic device or the second electronic device based on the scanned encryption protocol in the first target broadcast signal or the scanned encryption protocol in the second target broadcast signal, and communication connection is established with the first electronic device or the second electronic device.

In a possible implementation manner of the first aspect, the earphone is further configured to, in the off-box state, if the target broadcast signal is not scanned at the first scanning frequency, continue scanning at a second scanning frequency, where the second scanning frequency is smaller than the first scanning frequency.

For example, if the earphone does not scan the target broadcast signal with bluetooth low energy in the off state, the scanning frequency is reduced to save the earphone power consumption. Correspondingly, when the target broadcast signal is scanned at the reduced scanning frequency, the scanning frequency can be increased again, so that the scanned target broadcast signal can be responded in time when the earphone is opened, and a return connection is established with the electronic equipment.

In a second aspect, a headset connection system is provided, the system comprising a headset and a first electronic device;

In the above manner, the earphone can also send out a third target broadcast signal of a third broadcast frequency in the closed state, and the third target broadcast signal is used for enabling the first electronic device to find the earphone; after the first electronic equipment scans a third target broadcast signal of the earphone based on the third scanning frequency, the scanning frequency is increased, and the scanning frequency continues to scan at a fourth scanning frequency, so that when the earphone is opened, the open-box broadcast signal of the earphone can be scanned more timely, communication connection signals can be sent to the earphone timely, and the return connection with the earphone can be established quickly.

In a possible implementation manner of the second aspect, the earphone is configured to send out, in an off-box state, a third target broadcast signal including a third encryption protocol at a third broadcast frequency; the first electronic device is further configured to send a communication connection signal to the headset based on a third encryption protocol when the open-box broadcast signal is scanned after the third target broadcast signal is scanned, and establish a communication connection with the headset.

Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to illustrate the technical solutions described in the present application, the following description is made by specific examples.

It is also to be understood that the terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

As used in this specification and the appended claims, the term "if" may be interpreted as "when..once" or "in response to a determination" or "in response to detection" depending on the context. Similarly, the phrase "if a determination" or "if a [ described condition or event ] is detected" may be interpreted in the context of meaning "upon determination" or "in response to determination" or "upon detection of a [ described condition or event ]" or "in response to detection of a [ described condition or event ]".

Currently, for dual-connection wireless bluetooth headsets, a wireless communication connection may be established with two or more devices simultaneously. However, in the reconnection mechanism, after the earphone is opened, it is necessary to perform reconnection judgment on the devices connected in sequence for the last time. As shown in fig. 1 (a), the dual-connection electronic device takes a mobile phone a and a mobile phone B as an example, when the mobile phone a and the mobile phone B are electronic devices that are paired with the headset last time and are located in a connectable range of the headset, after the headset is opened, a reconnection request is respectively and sequentially initiated to the mobile phone a and the mobile phone B based on a connection sequence fixed in a reconnection mechanism, after the mobile phone a is fed back and connected into work, the headset initiates the reconnection request to the mobile phone B, and after the mobile phone B is fed back and connected into work, communication channels between the headset and the mobile phone a and the mobile phone B are formally started.

However, as shown in fig. 1 (b), a handset state determines and does not first connect back to the scene. When the state of one of the electronic devices (for example, the mobile phone A) is uncertain, for example, the mobile phone A is not in the connectable range of the earphone or the Bluetooth is closed, and the like, after the earphone is opened, the connection sequence based on the original fixed connection mechanism is needed, a connection request is firstly initiated to the mobile phone A, and after waiting for feedback timeout, the connection process of the mobile phone A is ended; and a reconnection request is initiated to the mobile phone B only when the reconnection of the mobile phone A fails, and the mobile phone B starts to work based on a communication channel with the mobile phone B after the feedback connection of the mobile phone B is successful. The waiting time of the mobile phone A with uncertain state in the reconnection judging process is long, so that the reconnection time of the earphone and the mobile phone B is too long, the reconnection response of the earphone and the electronic equipment is slower, and the experience of a user is affected.

Also, as shown in fig. 1 (c), a handset status determines and first links back to the scene. When the state of the mobile phone B is uncertain, for example, the mobile phone B is not in the connectable range of the earphone or the Bluetooth of the mobile phone B is closed, after the earphone is opened, based on the fixed connection sequence in the original reconnection mechanism, after the mobile phone B is connected with the mobile phone A in a reconnection mode, a reconnection request is initiated to the mobile phone B, as the state of the mobile phone B is uncertain, the disconnection failure of the mobile phone B is determined after waiting for timeout, and the operation starts based on the communication connection between the mobile phone A and the earphone after the disconnection failure of the mobile phone B is determined, so that the time consumption for working response is long after the earphone is connected with the electronic equipment in a reconnection mode, the response efficiency is low, and the experience of the user is influenced.

Aiming at the defects, the application provides the earphone reconnection system which can shorten the reconnection time of the earphone and the electronic equipment and improve the reconnection efficiency and the work response efficiency of the earphone and the electronic equipment.

Referring to fig. 2, fig. 2 is a schematic diagram of an earphone connection system according to an embodiment of the present application. As shown in fig. 2, the system may include a first electronic device 10, an earphone 20, and a second electronic device 30.

For example, in some application scenarios, the system may also include only one electronic device and headphones, such as the first electronic device 10 and headphones 20, or the second electronic device 30 and headphones.

As shown in fig. 2, if the first electronic device 10 and the second electronic device 30 are in a connectable state, the headset 20 may establish a communication connection with the first electronic device 10 and the second electronic device 30, respectively, after opening the case. In order to improve the efficiency of establishing a reconnection between the headset 20 and the electronic device, in the embodiment of the present application, the target broadcast signal sent by the electronic device may be scanned in the headset closed state to determine the connectable device located in the connection range, and a reconnection request may be quickly initiated to the connectable device when the headset is opened. Or when the electronic equipment is disconnected with the earphone, the earphone can send out a target broadcast signal of the low-power consumption Bluetooth in a closed box state, and the electronic equipment can actively initiate a connection return request to the earphone to establish communication connection when the earphone is opened based on the scanned target broadcast signal.

The target broadcast signal is, for example, a broadcast signal for which the electronic device and the headset are known to agree on and identifiable to respond, e.g., the target broadcast signal may include an encryption protocol agreed by the headset and the electronic device, which may be generated when the electronic device and the headset first establish a pairing connection. After the earphone is opened, communication connection can be respectively established with the first electronic device and the second electronic device, as shown in fig. 2, and information such as a connection state and an electric quantity state of the connected earphone can be displayed on display interfaces of the first electronic device and the second electronic device.

By way of example, the electronic device that establishes a wireless communication connection with the headset may be a terminal that can communicate wirelessly, such as a mobile phone, a tablet, a notebook, etc., and the type of the electronic device is not limited herein.

It should be noted that, the process of the target broadcast signal based on bluetooth low energy broadcast, the scanning identification of the target broadcast signal and the reconnection can be applied to a scenario where a single electronic device establishes reconnection with an earphone, or a scenario where two or more devices establish reconnection with an earphone; based on the above-mentioned back connection mechanism, can improve the defect that the waiting time is too long because the state of the electronic equipment is uncertain and based on the fixed connection sequence in the original back connection mechanism, have raised the speed that earphone and electronic equipment are back connected; and the earphone can enter the service state quickly without waiting for the connection judgment of other electronic equipment in uncertain states.

Aiming at the scene that the earphone and the electronic equipment are connected in a pairing way, and are connected again after the communication connection is disconnected, the implementation process of quickly establishing the connection between the earphone and the electronic equipment is described in detail through a specific embodiment. The first electronic device is taken as a mobile phone B, and the second electronic device is taken as a mobile phone A for exemplary illustration.

Firstly, the earphone is introduced as a scanning end, and the electronic equipment is used as a broadcasting end, so that the earphone and the electronic equipment realize the process of reconnection.

Example 1

As shown in fig. 3, the earphone connection system includes an earphone and a first electronic device (hereinafter, described by taking a mobile phone B as an example). After the mobile phone B is disconnected from the earphone, the mobile phone B sends out a first target broadcast signal at a first broadcast frequency, for example, sends out a first target broadcast signal of bluetooth low energy every 10 seconds. The earphone wakes up at the first scanning frequency in a closed state and continuously scans the target broadcast signal for a certain time; for example, when the earphone is in the off state, wake up every 20 minutes, and scan for 15 seconds.

The first target broadcast signal may be an encrypted broadcast including an encryption protocol. The encryption protocol can be generated by convention when the earphone is connected with the electronic equipment in a first pairing mode; the first target broadcast signal may include identification information of the electronic device that sent the broadcast, such as a model number or a name of the mobile phone B.

In some embodiments, after the headset scans the first target broadcast signal in the off-box state, it may be determined that the handset B is within the connectable range and in the connectable state. When the earphone is opened, a communication connection signal can be sent to the mobile phone B based on the scanned first target broadcast signal, a connection return request is initiated to the mobile phone B, and communication connection is established with the mobile phone B.

In an exemplary embodiment, the headset may enter a bluetooth low energy operating state when in a closed state and the first electronic device may enter a bluetooth low energy operating state when disconnected from the headset, for example, the headset may enter a bluetooth low energy scanning state when in a closed state, and the first electronic device may enter a bluetooth low energy signal broadcasting state when disconnected from the headset.

The first electronic device may be a mobile phone, a tablet computer, a notebook computer or the like capable of wireless communication. The first broadcasting frequency of the first electronic device may be set based on the habit of the user in the use period, for example, low-power broadcasting is started in daytime and is closed at night; or different broadcast frequencies for different time periods during the day, etc.

In one possible implementation manner, the above-mentioned reconnection mechanism is also applicable to the mobile phone a, that is, the first electronic device may also be an electronic device with a connection sequence in the history connection information arranged at the first position, where after the earphone scans the target broadcast signal sent by the mobile phone a in the closed box state, the earphone preferentially establishes reconnection with the mobile phone a after opening the box; and when the target broadcast signal of the mobile phone B is not scanned, after the reconnection with the mobile phone A is successfully established, the mobile phone B is not tried to be reconnected, and after the reconnection with the mobile phone A is successful, the mobile phone B directly enters an operation state, and the reconnection judgment with the mobile phone B is not needed. That is, no matter the device to be connected currently scanned by the earphone is the preceding or following electronic device in the original inherent connection sequence, when the earphone is closed and only the target broadcast signal of one electronic device is scanned, only the connection is preferentially established and only the connection is established with the scanned one electronic device, and after the connection is successful, the connection state of the other electronic device is not judged. As shown in fig. 7, a display interface is set on the earphone of the electronic device (mobile phone B), and the dual-device connection control interface only displays one device connected with the earphone; or as shown in fig. 8, the first connection of the headset and the plurality of electronic devices after pairing is established, only one device (mobile phone B) which establishes communication connection with the headset can be highlighted during reconnection, and other connected devices (mobile phone a and tablet iPad) can be displayed at the same time, but the other connected devices (mobile phone a and tablet iPad) can be displayed in a gray scale to indicate that the other connected devices are currently in an unconnected state.

By the method, after the earphone is disconnected from the electronic equipment, the earphone scans a target broadcast signal sent by the mobile phone B in a box closing state, the state of the mobile phone B can be determined based on the target broadcast signal, and then a reconnection request can be timely initiated to the mobile phone B after the box is opened, whether the mobile phone B is in the first connection order or not is not confirmed based on the connection order of other electronic equipment in the history connection information, and the time for performing reconnection judgment with other electronic equipment in the history connection information is not required, so that when only one electronic equipment is in a connectable state and within a connectable range, the reconnection speed of the double-connection earphone can be greatly improved, the working state can be immediately entered after the reconnection is established, the time for reconnection with other electronic equipment is not required to be waited, and the response efficiency of the earphone entering the service state after the reconnection is established is improved.

As shown in fig. 4, the earphone connection system may further include an earphone, a first electronic device, and a second electronic device; the second electronic device may also send a bluetooth low energy signal, that is, a second target broadcast signal after being disconnected from the headset, where the second target broadcast signal may include a second encryption protocol and a device identifier of the second electronic device, for example, information such as a device model number or a name. The following description will take the first electronic device as a mobile phone B and the second electronic device as a mobile phone a as examples.

For example, handset B sends out a first target broadcast signal at a first broadcast frequency, and handset a sends out a second target broadcast signal at a second broadcast frequency; the first broadcast frequency and the second broadcast frequency may be the same broadcast frequency or different broadcast frequencies; the earphone scans the target broadcast signal at a first scanning frequency in the off-box state.

As shown in fig. 4, in the current certain period of time, the solid line corresponding to the mobile phone B represents a target broadcast signal sent out in the scannable range of the earphone; the dotted line part corresponding to the mobile phone A does not emit the target broadcast signal within the scannable range of the earphone, the solid line part corresponds to the target broadcast signal emitted within the scannable range of the earphone, namely, the solid line part corresponds to the target broadcast signal which can be scanned by the earphone in the closed box state, and the dotted line part corresponds to the target broadcast signal which cannot be scanned by the earphone.

In one possible implementation, during the scanning process of the closed-box state, the earphone may also record a time node when the target signal is scanned for the first time, or record the number or frequency of scanning the target signal through a counter. For example, in a current certain time period, the earphone can record a time node of the mobile phone B scanned for the first time in a closed box state, and initiate a reconnection request to the mobile phone B after determining to open the box based on the time node; or recording the times or frequency of the target broadcast signals scanned in the scanning process, for example, if the mobile phone B is always in the scannable range of the earphone, the 5 times of target broadcast signals sent by the mobile phone B can be counted, and the mobile phone A is not always in the scannable range of the earphone, and the earphone can only scan the target broadcast signals sent by the mobile phone A twice; and determining that the mobile phone B is equipment to be connected with stable state based on the times of the scanned target broadcast signals, and after the mobile phone B is opened, firstly initiating a reconnection request to the mobile phone B, namely firstly sending a communication connection signal to the mobile phone B by the earphone, firstly establishing reconnection with the mobile phone B, and after the reconnection is successful, initiating the reconnection request to the mobile phone A, and establishing communication connection with the mobile phone A.

For example, a threshold value of the number of times of scanning the target broadcast signal can be set in the earphone, and when the threshold value is not reached, even if the corresponding target broadcast signal is scanned in the off-box state, no reconnection is performed; as shown in fig. 4, if the earphone scans only one target broadcast signal of the mobile phone a, and the number of times does not reach the threshold value, it is possible that the mobile phone a only has a scene of leaving in the connectable range of the earphone, so that only based on the scanned target broadcast signal sent by the mobile phone B, a connection is preferentially established with the mobile phone B only; therefore, the reliability of the reconnection is guaranteed while the timeliness of the reconnection is guaranteed, and the probability of invalid reconnection and the time consumption caused by the invalid reconnection are reduced.

In an exemplary embodiment, when the earphone is opened, the communication connection signal is sent to the first electronic device based on the scanned first target broadcast signal, or the communication connection signal is sent to the second electronic device based on the scanned second target broadcast signal, so that communication connection is respectively established with the first electronic device or the second electronic device. When the earphone and the plurality of electronic devices are connected in a paired manner, the first electronic device and the second electronic device are two of the plurality of electronic devices, and when the earphone scans the first target broadcast signal or the second target broadcast signal, a return connection can be established with only one of the two electronic devices, or the return connection can be established with the two electronic devices respectively based on the state of the scanned target signal.

As shown in fig. 8, a display interface is set on the earphone of the electronic device (mobile phone B), a control interface is connected to the dual device, two devices connected to the earphone (mobile phone a and mobile phone B, mobile phone B are connected as priority) are highlighted, and other connected devices can be displayed at the same time, but the other connected devices are shown in the unconnected state currently by gray scale display, such as the tablet iPad shown in fig. 8.

After the earphone and the electronic equipment are connected back to work, the earphone can clear the recorded time nodes or the recorded scanned times and other information during the back connection; or after the connection is finished once, namely the earphone and the electronic equipment are disconnected and returned to the closed box state, the earphone can clear the information such as the time node recorded in the last time of the connection or the recorded scanned times; and starts re-recording when the next off-box condition scans the target broadcast signal.

By the method, the earphone does not need to establish a reconnection with the connectable electronic equipment based on the inherent connection sequence in the historical connection information, and in order to reduce the probability of the prolonged reconnection time due to the uncertain electronic equipment in the state, the electronic equipment which is connected preferentially can be determined based on the state of the target broadcast signal scanned in the off-box state, so that the timeliness and the reliability of the reconnection of the earphone and the electronic equipment are improved.

Based on the implementation manner of the first and second embodiments, the earphone is used as a scanning end, wakes up at a first scanning frequency and scans for a period of time at regular time, and if the target broadcast signal is not scanned at the first scanning frequency, the scanning frequency is reduced, or the duration of one scanning is shortened, and the scanning is continued at a second scanning frequency after the frequency is reduced or the scanning time period of one scanning duration is shortened, so as to save the power consumption of the earphone.

And introducing the earphone as a broadcasting end and the electronic equipment as a scanning end, so that the earphone and the electronic equipment realize the process of reconnection.

Example III

As shown in fig. 5, the earphone connection system includes an earphone and a first electronic device (hereinafter, described by taking a mobile phone B as an example). Wherein the earphone sends out a first target broadcast signal at a third broadcast frequency in a closed state, for example, a first target broadcast signal of bluetooth low energy is sent every 10 seconds; the target broadcast signal may contain information such as the device identification of the headset, for example, the model or name of the headset. After the mobile phone B is disconnected with the earphone, the scanning mechanism is awakened at a third scanning frequency at fixed time, and broadcast signals are continuously scanned for a certain time; for example, when the first electronic device is disconnected from the headset, the scanning mechanism wakes up every 20 minutes for 15 seconds.

In an exemplary embodiment, after the mobile phone B scans the target broadcast signal of the headset with the third scanning frequency, the scanning frequency is increased, the scanning mechanism is periodically awakened with the fourth scanning frequency, scanning is continued, when the headset is opened to send the open-box broadcast signal, the mobile phone B can quickly scan the open-box broadcast signal, timely find the open-box state of the headset, actively send a communication connection signal to the headset, initiate a connection request to the headset, and after the communication connection is established, the headset feeds back information of successful connection to the mobile phone B, so as to start entering a service state.

In one possible implementation, the earphone sends out a third target broadcast signal containing a third encryption protocol at a third broadcast frequency in a closed-box state; after the first electronic device scans the third target broadcast signal, the first electronic device sends a communication connection signal to the earphone based on a third encryption protocol when scanning the open-box broadcast signal, and communication connection is established with the earphone.

The first embodiment is similar to the second embodiment in that the target broadcast signal broadcast by the earphone is an encrypted broadcast signal including an encryption protocol, and after the electronic device scans the target broadcast signal, the electronic device can determine that the earphone is located in a connectable range and increase the scanning frequency, and discover an open-box broadcast signal sent by the earphone when the earphone is opened, so that a quick and active connection is established with the earphone.

The first electronic device may determine that the connectable earphone is nearby only after the first electronic device scans the third target broadcast signal including the third encryption protocol, and after the earphone is opened, respond based on the scanned open-box broadcast signal, and actively initiate a reconnection to the earphone.

It should be noted that, when the mobile phone a is in the scanning state, the implementation principle is the same as that of the mobile phone B, that is, the above-mentioned reconnection mechanism is also applicable to the mobile phone a. The first electronic device may be an electronic device with connection sequence arranged at the top in the history connection information, after the mobile phone a scans the target broadcast signal sent by the earphone in the off-box state, the scanning frequency is increased, and after the open-box broadcast signal of the earphone is scanned, the mobile phone a actively establishes a return connection with the earphone; when the target broadcast signal of the mobile phone B is not scanned, after the mobile phone A and the earphone are successfully connected back, the earphone can not try to connect back to the mobile phone B any more, and after the mobile phone A is connected back to work, the mobile phone B directly enters an operation state, so that the judgment of connecting back to the mobile phone B is not needed; because the mobile phone B is not involved in the scanning process, the natural mobile phone B can not actively initiate a reconnection request; the time for connecting the earphone with the electronic equipment is shortened, and the efficiency for connecting the earphone with the electronic equipment is improved. That is, no matter the electronic device performing the scanning action is the preceding or following electronic device in the original inherent connection sequence, when only one electronic device scans the target broadcast signal in the earphone closed box state, the one electronic device can actively initiate a reconnection request to the earphone, and after the reconnection becomes successful, the business state can be entered without judging the reconnection state of the other electronic device. As shown in fig. 7, a display interface is set on the earphone of the electronic device (mobile phone B), and the dual-device connection control interface only displays one device connected with the earphone; or as shown in fig. 8, the first connection of the headset and the plurality of electronic devices after pairing is established, only one device (mobile phone B) which establishes communication connection with the headset can be highlighted during reconnection, and other connected devices (mobile phone a and tablet iPad) can be displayed at the same time, but the other connected devices (mobile phone a and tablet iPad) can be displayed in a gray scale to indicate that the other connected devices are currently in an unconnected state.

By the method, after the first electronic equipment scans the third target broadcast signal of the earphone based on the third scanning frequency, the scanning frequency is increased, and the scanning is continued at the fourth scanning frequency, so that when the earphone is opened, the box-opening broadcast signal of the earphone can be scanned more timely, communication connection signals are sent to the earphone in time, the reconnection is established with the earphone quickly, and the reconnection time length is increased without judging the doubly-connected equipment every time.

Example IV

As shown in fig. 6, the earphone connection system may further include an earphone, a first electronic device, and a second electronic device; after the second electronic device is disconnected from the earphone, the target broadcast signal sent by the earphone in the off-box state can be scanned based on the bluetooth low energy, and the target broadcast signal can include an encryption protocol and equipment identification of the earphone, such as information of the model or name of the earphone. The following description will take the first electronic device as a mobile phone B and the second electronic device as a mobile phone a as examples.

In one possible implementation, the earphone sends out a third target broadcast signal containing the desired connection sequence at a third broadcast frequency in the off-box state; and after the first electronic device and the second electronic device scan the third target broadcast signal and the earphone is opened, sending communication connection signals to the earphone based on the expected connection sequence, and respectively establishing communication connection with the earphone.

For example, for a dual-connection earphone, the third target broadcast signal including the third encryption protocol may further carry an expected connection sequence of the earphone, where the expected connection sequence may be set based on a time habit or a scene of using the earphone by a user, for example, when the earphone is paired with the electronic device for the first time or in a connection state between the electronic device and the earphone, the expected connection sequence of the earphone may be set based on the electronic device, so that the earphone receives information of the expected connection sequence transmitted by the electronic device and sets according to a corresponding time or a corresponding scene; so that in the off-box state, the headset can emit a target broadcast signal with a desired connection order based on the corresponding time or scene.

The electronic device may also identify a desired connection order in the target broadcast signal after scanning the target broadcast signal broadcast by the headset, and establish a connection with the headset based on the desired connection order after scanning the open-box broadcast signal.

For example, the desired connection sequence may include an identification of one or both devices to be connected.

As shown in fig. 6, in the first case, when the expected connection sequence includes an identifier of a device to be connected, after the electronic device corresponding to the identifier scans the target broadcast signal, a connection is quickly established with the earphone based on the expected connection sequence, the earphone does not wait for the connection of another electronic device, and directly enters a working state with the electronic device that has been successfully connected; thereby improving the efficiency of the connection between the earphone and the electronic equipment.

As shown in fig. 6, in the second case, when the expected connection sequence includes the identifiers of two devices to be connected, the identifiers of the two devices to be connected are provided with serial numbers for indicating the connection in sequence; after the electronic equipment scans the target broadcast signal and identifies the serial numbers of the sequential connection in the target broadcast signal, sequentially establishing a back connection to the earphone based on the serial numbers in the expected connection sequence; and after receiving the box-opening broadcast signal, the electronic equipment with the first serial number preferentially initiates back connection to the earphone based on the expected connection sequence in the target broadcast signal.

If the communication connection is preferentially established in the expected connection sequence, the mobile phone B actively connects back to the earphone based on the expected connection sequence after scanning the earphone open-box broadcast signal, and receives information of successful connection feedback from the earphone; meanwhile, the earphone initiates a reconnection to the mobile phone A and starts to enter a service state after receiving information of the successful reconnection fed back by the mobile phone A; or after the earphone feeds back the information of successful connection back to the mobile phone B, feeding back the information of successful connection back to the mobile phone A, and then actively initiating a connection back request to the earphone, and after the connection back success is established, feeding back the information of the connection success to the mobile phone A by the earphone, and entering a service state.

It should be noted that, the fourth embodiment only represents one possible implementation of the dual-connection application scenario; the method aims at a reconnection mechanism which stores a desired connection sequence in the earphone and sends out low-power consumption Bluetooth broadcasting in a closed box state. The expected connection sequence in the reconnection mechanism can be set and stored based on the use time or the application scene when the electronic equipment is in a connection state with the earphone, for example, only the earphone is required to be connected with one electronic equipment (for example, a mobile phone B) in the morning, and the target broadcast signal with the expected connection sequence sent by the earphone can only contain the equipment identification information of the mobile phone B based on the reconnection mechanism; if the user returns home at night, when the user uses the earphone, the two electronic devices of the tablet and the mobile phone may need to be connected at the same time, and the target broadcast signal with the expected connection sequence sent by the earphone may include the device identifiers of the mobile phone and the tablet and be sequenced, for example, the mobile phone is connected with the tablet first and the tablet is connected with the tablet later; and the time period can be correspondingly and rapidly realized based on the reconnection mechanism.

Through the mode, the judgment of the double-device reconnection state is not needed when the earphone is connected with the electronic device every time, the expected connection sequence of the earphone reconnection can be preset in advance, the earphone and the electronic device are quickly connected in a corresponding application scene or time period, the probability of invalid reconnection is reduced, the reconnection efficiency of the earphone and the device is improved, and the experience of a user is improved.

It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, a UART interface is typically used to connect the processor 110 with the wireless communication module 160. For example: the processor 110 communicates with a bluetooth module in the wireless communication module 160 through a UART interface to implement a bluetooth function. In some embodiments, the audio module 170 may transmit an audio signal to the wireless communication module 160 through a UART interface, to implement a function of playing music through a bluetooth headset.

The MIPI interface may be used to connect the processor 110 to peripheral devices such as a display 194, a camera 193, and the like.
