Description

[0001] This application is a divisional application of the Chinese patent application submitted to the State Intellectual Property Office on August 23, 2022, with application number 202211012343.0 and application name "Headphone connection system, method, headphone, electronic device and readable storage medium". Technical Field

[0002] The present application relates to the field of terminal technology, and in particular to an earphone connection system, method, earphone, electronic device and readable storage medium. Background Art

[0003] At present, wireless headphones can generally connect to other electronic devices through built-in wireless communication components such as Bluetooth, establish wireless communication channels, and realize the transmission of audio and other data.

[0004] However, for a headset that can simultaneously establish wireless communication connections with two or more other electronic devices, when reconnecting with the other electronic devices, it takes too long to reconnect because the status of the other electronic devices does not meet the connection expectations. Summary of the invention

[0005] The present application provides an earphone connection system, method, earphone, electronic device and readable storage medium, which solves the problem of long reconnection time caused by the status of other electronic devices not meeting expectations.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a headset connection system is provided, which may include a headset and a first electronic device;

[0008] The first electronic device is used to send a first target broadcast signal at a first broadcast frequency after being disconnected from the headset; the headset is used to scan the first target broadcast signal at a first scanning frequency when the box is closed, and when the box is opened, send a communication connection signal to the first electronic device based on the scanned first target broadcast signal to establish a communication connection with the first electronic device.

[0009] Exemplarily, for headphones that can establish communication connections with multiple devices, such as dual-connection headphones, when only one electronic device is preparing to reconnect with the headphones, the headphones can determine the electronic devices that are in place and can be connected by scanning the target broadcast signal emitted by the electronic device when the connection is disconnected, and can promptly send a communication connection signal to the electronic device that is in place and emits the target broadcast signal after opening the box to quickly establish a communication connection; there is no need to make connection judgments for all devices in the historical connection information in order of historical connection based on historical connection records, thereby greatly saving the reconnection time of the headphones; at the same time, when the headphones scan that an electronic device is in place, they only need to establish a communication connection with the electronic device, and there is no need to make reconnection judgments for all connected electronic devices again after each opening of the box; while saving the reconnection time of the headphones, the connected headphones can quickly enter the operating state.

[0010] Through the above method, when the earphones are opened, they can quickly send a communication connection signal to the first electronic device based on the first target broadcast signal scanned in the closed box state, and initiate a communication connection with the electronic device; thereby, in the closed box state, the connectable electronic devices that meet the connection state are determined in advance, and there is no need to initiate a reconnection judgment for the electronic devices in the uncertain state based on the historical connection information, which causes the connection to be time-consuming, thereby improving the speed of reconnection between the earphones and the electronic device; it has strong ease of use and practicality.

[0011] In a possible implementation of the first aspect, the system also includes a second electronic device; the second electronic device is used to send a second target broadcast signal at a second broadcast frequency after being disconnected from the headset; the headset is also used to scan the second target broadcast signal at a first scanning frequency in a closed box state, and when the box is opened, send a communication connection signal to the first electronic device based on scanning the first target broadcast signal, or send a communication connection signal to the second electronic device based on scanning the second target broadcast signal, to establish a communication connection with the first electronic device or the second electronic device, respectively.

[0012] For example, when there are two electronic devices in the waiting state near the headset, both of which emit low-power Bluetooth target broadcast signals, the headset can determine the connection order of the devices to be connected based on the frequency or order of the scanned target broadcast signals; or, when the headset is unpacked, the electronic device to be connected is determined based on the first scanned target broadcast signal. This eliminates the need to verify the reconnection in sequence based on a fixed connection order each time, thereby improving the efficiency of the headset reconnection.

[0013] In a possible implementation of the first aspect, the first electronic device is further used to send a first target broadcast signal including a first encryption protocol at a first broadcast frequency after being disconnected from the headset; the headset is further used to send a communication connection signal to the first electronic device based on the first encryption protocol in the scanned first target broadcast signal when the box is opened, so as to establish a communication connection with the first electronic device.

[0014] Exemplarily, the encryption protocol may be a known protocol content agreed upon between the headset and the electronic device, and the encryption protocol may be agreed upon and generated when the headset and the electronic device establish a connection for the first time.

[0015] Therefore, when the earphones are disconnected from the electronic device, by scanning the target broadcast signal containing the encryption protocol, it can be determined that the electronic device to be connected is within the connectable range. When the earphones are opened, based on the scanned target broadcast signal, it can immediately respond and establish a backconnection with the determined electronic device.

[0016] Exemplarily, the first electronic device or the second electronic device is used to send a first target broadcast signal or a second target broadcast signal containing an encryption protocol after being disconnected from the headset; the headset is also used to determine that the device to be connected is the first electronic device or the second electronic device based on the encryption protocol in the first target broadcast signal or the second target broadcast signal; and when opening the box, a communication connection signal is sent to the first electronic device or the second electronic device based on the encryption protocol in the scanned first target broadcast signal or the encryption protocol in the second target broadcast signal, so as to establish a communication connection with the first electronic device or the second electronic device.

[0017] In a possible implementation of the first aspect, the headset is further configured to continue scanning at a second scanning frequency if the target broadcast signal is not scanned at the first scanning frequency in a box-off state, and the second scanning frequency is lower than the first scanning frequency.

[0018] For example, if the headset fails to scan the target broadcast signal with low-power Bluetooth in the closed state, the scanning frequency is reduced to save the power consumption of the headset. Correspondingly, when the target broadcast signal is scanned with the reduced scanning frequency, the scanning frequency can be increased again to respond to the scanned target broadcast signal in time when the headset is opened and establish a back connection with the electronic device.

[0019] In a second aspect, a headset connection system is provided, the system comprising a headset and a first electronic device;

[0020] The earphones are used to send out a third target broadcast signal at a third broadcast frequency when the earphones are in a closed state; the first electronic device is used to scan the third target broadcast signal at a third scanning frequency after being disconnected from the earphones, and to continue scanning at a fourth scanning frequency after scanning the third target broadcast signal; the first electronic device is also used to send a communication connection signal to the earphones after the earphones are opened, based on the scanned third target broadcast signal and the earphones' opening broadcast signal, so as to establish a communication connection with the earphones; wherein the fourth scanning frequency is greater than the third scanning frequency.

[0021] Through the above method, the earphones can also emit a third target broadcast signal of a third broadcast frequency in a closed box state, and the third target broadcast signal is used to enable the first electronic device to discover the earphones; and after the first electronic device scans the third target broadcast signal of the earphones based on the third scanning frequency, it increases the scanning frequency and continues to scan at the fourth scanning frequency, so that when the earphones are opened, the earphones' opening broadcast signal can be scanned more promptly, and a communication connection signal can be sent to the earphones in a timely manner to quickly establish a back connection with the earphones.

[0022] In a possible implementation of the second aspect, the headset is used to emit a third target broadcast signal including a third encryption protocol at a third broadcast frequency in a box-off state; the first electronic device is also used to send a communication connection signal to the headset based on the third encryption protocol when scanning an open-box broadcast signal after scanning the third target broadcast signal, thereby establishing a communication connection with the headset.

[0023] Exemplarily, the third encryption protocol contained in the third target broadcast signal may be an encryption protocol generated when the headset is paired and connected with the electronic device for the first time, that is, the headset may broadcast a third target broadcast signal containing the third encryption protocol, so as to distinguish other scanned broadcast signals. Only after the first electronic device scans the third target broadcast signal containing the third encryption protocol, it determines that the connectable headset is nearby, and responds after the headset is unboxed, and actively initiates a connection back to the headset.

[0090] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0091] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0092] It should be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0093] It should also be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0094] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0095] As used in this specification and the appended claims, the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if [described condition or event] is detected" may be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0096] Currently, dual-connection wireless Bluetooth headsets can establish wireless communication connections with two or more devices at the same time. However, due to the reconnection mechanism, after the headset is unpacked, it is necessary to reconnect to the last connected device in turn. Figure 1 As shown in Figure (a), the dual-connected electronic devices take mobile phone A and mobile phone B as an example. When mobile phone A and mobile phone B are electronic devices that have been paired and connected with the headset last time and are within the connectable range of the headset, when the headset is unboxed, based on the fixed connection sequence in the reconnection mechanism, reconnection requests are initiated to mobile phone A and mobile phone B respectively. After mobile phone A feedbacks that the reconnection is successful, the headset initiates a reconnection request to mobile phone B. After mobile phone B feedbacks that the connection is successful, the communication channel between the headset and mobile phones A and B officially starts working.

[0097] However, if Figure 1 As shown in Figure (b), a scenario where the state of a mobile phone is determined and it does not reconnect first. When the state of one of the electronic devices (such as mobile phone A) is uncertain, for example, mobile phone A is not within the connectable range of the headset or the Bluetooth is turned off, after the headset is unpacked, it is necessary to first initiate a reconnection request to mobile phone A based on the connection sequence of the original fixed reconnection mechanism, and only after waiting for the feedback timeout will the reconnection process to mobile phone A be ended; if the reconnection to mobile phone A fails, it will initiate a reconnection request to mobile phone B again, and after mobile phone B feedbacks that the connection is successful, it will start working based on the communication channel with mobile phone B. Since the waiting time for the reconnection judgment process of mobile phone A with an uncertain state is long, the reconnection time between the headset and mobile phone B is too long, resulting in a slow response to the reconnection between the headset and the electronic device, affecting the user experience.

[0098] Moreover, if Figure 1As shown in Figure (c), a scenario where the state of a mobile phone is determined and the phone reconnects first. When the state of mobile phone B is uncertain, for example, mobile phone B is not within the connectable range of the headset or the Bluetooth of mobile phone B is turned off, the headset, after unpacking, based on the fixed connection sequence in the original reconnection mechanism, initiates a reconnection request to mobile phone B after successfully reconnecting with mobile phone A. Due to the uncertain state of mobile phone B, it is determined that mobile phone B has failed to reconnect after a timeout, and only after it is determined that mobile phone B has failed to reconnect does it start to work based on the communication connection between mobile phone A and the headset, which makes it take a long time for the headset to respond to the electronic device after reconnecting, and the response efficiency is low, which also affects the user experience.

[0099] In view of the above-mentioned defects, the present application provides an earphone reconnection system, which can shorten the reconnection time between the earphone and the electronic device, and improve the reconnection efficiency and work response efficiency between the earphone and the electronic device.

[0100] See also Figure 2 , Figure 2 : is a diagram of the headset connection system architecture provided by the embodiment of the present application. Figure 2 As shown, the system may include a first electronic device 10 , a headset 20 , and a second electronic device 30 .

[0101] Exemplarily, in some application scenarios, the system may also include only one electronic device and a headset, such as a first electronic device 10 and a headset 20, or a second electronic device 30 and a headset.

[0102] like Figure 2 As shown, if the first electronic device 10 and the second electronic device 30 are in a connectable state, the headset 20 can respectively establish communication connections with the first electronic device 10 and the second electronic device 30 after the box is opened. In order to improve the efficiency of the headset 20 in establishing a back connection with the electronic device, in an embodiment of the present application, the headset can scan the target broadcast signal emitted by the electronic device in the box-off state to determine the connectable device within the connection range, and quickly initiate a backconnection request to the connectable device when the box is opened. Alternatively, when the electronic device is disconnected from the headset, the headset can emit a low-power Bluetooth target broadcast signal in the box-off state, and the electronic device can actively initiate a backconnection request to the headset when the headset is opened based on the scanned target broadcast signal to establish a communication connection.

[0103] Exemplarily, the target broadcast signal is a broadcast signal that the electronic device and the headset have known and agreed upon and can recognize and respond to. For example, the target broadcast signal may include an encryption protocol agreed upon by the headset and the electronic device, and the encryption protocol may be generated when the electronic device and the headset establish a pairing connection for the first time. After the headset is unpacked, a communication connection may be established with the first electronic device and the second electronic device, respectively. Figure 2As shown, the display interface of the first electronic device and the second electronic device can also display information such as the connection status and power status of the connected headphones.

[0104] Exemplarily, the electronic device that establishes a wireless communication connection with the headset may be a terminal capable of wireless communication, such as a mobile phone, a tablet, or a laptop computer, and the type of the electronic device is not limited herein.

[0105] It should be noted that the above-mentioned target broadcast signal based on low-power Bluetooth broadcasting, scanning and identifying the target broadcast signal, and the reconnection process can be applicable to the scenario of establishing a reconnection between a single electronic device and the headset, and can also be applied to the scenario of establishing a reconnection between two or more devices and the headset; based on the above-mentioned reconnection mechanism, the defect of the original reconnection mechanism in which the waiting time is too long due to the uncertain state of the electronic device and the fixed connection sequence can be improved, thereby improving the speed of reconnection between the headset and the electronic device; there is no need to wait for the reconnection judgment of other electronic devices in uncertain states, so that the headset can quickly enter the business state.

[0106] For the scenario where the headset and the electronic device have established a paired connection and are reconnected after the communication connection is disconnected, the following specific embodiments are used to describe in detail the implementation process of quickly reconnecting the headset and the electronic device. The first electronic device is mobile phone B and the second electronic device is mobile phone A for exemplary description.

[0107] First, the headset is used as a scanning end and the electronic device is used as a broadcasting end, so that the headset and the electronic device can be connected back.

[0108] Embodiment 1

[0109] like Figure 3 As shown, the headset connection system includes a headset and a first electronic device (hereinafter described by taking mobile phone B as an example). After the mobile phone B is disconnected from the headset, it sends a first target broadcast signal at a first broadcast frequency, for example, a first target broadcast signal of low-power Bluetooth is sent every 10 seconds. When the headset is in the off state, it wakes up regularly at the first scanning frequency and continuously scans the target broadcast signal for a certain period of time; for example, when the headset is in the off state, it wakes up once every 20 minutes and scans for 15 seconds each time.

[0110] Exemplarily, the first target broadcast signal may be an encrypted broadcast including an encryption protocol. The encryption protocol may be generated by agreement when the headset and the electronic device are first paired and connected; the first target broadcast signal may include identification information of the electronic device that sends the broadcast, such as the model or name of mobile phone B.

[0111] In some embodiments, after the headset scans the first target broadcast signal in the closed state, it can be determined that mobile phone B is within the connectable range and is in a connectable state. When the headset is opened, it can first send a communication connection signal to mobile phone B based on the scanned first target broadcast signal, initiate a backconnect request to mobile phone B, and establish a communication connection with mobile phone B.

[0112] Exemplarily, the headset can enter a low-power Bluetooth working state when the box is turned off and the first electronic device is disconnected from the headset. For example, the headset enters a low-power Bluetooth scanning state when the box is turned off, and the first electronic device enters a low-power Bluetooth signal broadcasting state when the headset is disconnected.

[0113] For example, the first electronic device may be a terminal capable of wireless communication, such as a mobile phone, a tablet computer, or a laptop computer. The first broadcast frequency of the first electronic device may be set based on the user's usage time period, such as turning on low-power broadcasting during the day and turning it off at night; or setting different broadcast frequencies for different time periods during the day.

[0114] In one possible implementation, the above-mentioned reconnection mechanism is also applicable to mobile phone A, that is, the first electronic device can also be the electronic device that ranks first in the connection order in the historical connection information. After the headset scans the target broadcast signal emitted by mobile phone A in the closed state, it will prioritize to establish a reconnection with mobile phone A after opening the box; and when the target broadcast signal of mobile phone B is not scanned, after successfully establishing a reconnection with mobile phone A, it will not try to reconnect to mobile phone B. After successfully reconnecting with mobile phone A, it will directly enter the working state without the need to judge the reconnection with mobile phone B again. That is, no matter whether the device to be connected currently scanned by the headset is an electronic device that comes earlier or later in the original inherent connection order, when the headset scans the target broadcast signal of only one electronic device in the closed state, it will prioritize and only establish a reconnection with the scanned electronic device. After the reconnection is successful, the reconnection status of another electronic device will no longer be judged. Figure 7 As shown, in the headset setting display interface of the electronic device (mobile phone B), the dual-device connection control interface only displays one device connected to the headset; or as shown in FIG. Figure 8 As shown, the headset has established a paired connection with multiple electronic devices for the first time. When reconnecting, only one device (mobile phone B) that has established a communication connection with the headset can be highlighted, 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 grayscale to indicate that they are currently not connected.

[0115] Through the above method, after the headset is disconnected from the electronic device, the headset scans the target broadcast signal sent by mobile phone B in the box-off state, and can determine the status of mobile phone B based on the target broadcast signal, and then initiate a reconnection request to mobile phone B in time after opening the box. There is no need to confirm whether mobile phone B is the first connection order based on the order of connection with other electronic devices in the historical connection information, nor is there a need to wait for the time to make a reconnection judgment with other electronic devices in the historical connection information. Therefore, when only one electronic device is within the connectable range and in a connectable state, the reconnection speed of the dual-connected headset can be greatly improved, and after the reconnection is established, it can enter the working state immediately without waiting for the time to reconnect with other electronic devices, etc., thereby improving the response efficiency of the headset entering the business state after the reconnection is established.

[0116] Embodiment 2

[0117] like Figure 4 As shown, the headset connection system may also include a headset, a first electronic device and a second electronic device; wherein the second electronic device may also send a low-power Bluetooth signal, i.e., a second target broadcast signal, after being disconnected from the headset, and the second target broadcast signal may include a second encryption protocol and a device identifier of the second electronic device, such as a device model or name. The following is an example in which the first electronic device is mobile phone B and the second electronic device is mobile phone A.

[0118] Exemplarily, mobile phone B sends a first target broadcast signal at a first broadcast frequency, and mobile phone A sends a second target broadcast signal at a second broadcast frequency; the first broadcast frequency and the second broadcast frequency can be the same broadcast frequency or different broadcast frequencies; the headset scans the target broadcast signal at a first scanning frequency in the off state.

[0119] like Figure 4 As shown, in the current certain time period, the solid line corresponding to mobile phone B represents the target broadcast signal emitted within the scanning range of the headset; the dotted line corresponding to mobile phone A is the target broadcast signal that is not emitted within the scanning range of the headset, and the solid line portion corresponds to the target broadcast signal emitted within the scanning range of the headset, that is, the solid line portion corresponds to the target broadcast signal that can be scanned by the headset in the closed state, and the dotted line portion corresponds to the target broadcast signal that cannot be scanned by the headset.

[0120] In a possible implementation, during the scanning process in the closed box state, the headset can also record the time node when the target signal is first scanned, or record the number or frequency of scanning the target signal through a counter. For example, within a certain time period, the headset can record the time node when the mobile phone B is first scanned in the closed box state, and determine based on the time node to first initiate a reconnection request to mobile phone B after opening the box; or record the number or frequency of the target broadcast signal scanned during the scanning process, for example, if mobile phone B is always within the scanning range of the headset, then 5 target broadcast signals sent by mobile phone B can be counted, while mobile phone A is not always within the scanning range of the headset, and the headset may only scan the target broadcast signal sent by mobile phone A twice; based on the number of scanned target broadcast signals, it is determined that mobile phone B is a stable device to be connected, and a reconnection request is first initiated to mobile phone B after opening the box, that is, the headset first sends a communication connection signal to mobile phone B, and first establishes a reconnection with mobile phone B. After the reconnection is successful, a reconnection request is initiated to mobile phone A to establish a communication connection with mobile phone A.

[0121] For example, a threshold value of the number of times the target broadcast signal is scanned may be set in the headset. When the threshold value is not reached, even if the corresponding target broadcast signal is scanned in the off state, the headset will not be reconnected. Figure 4 As shown, if the headset scans the target broadcast signal of mobile phone A only once and the number of times does not reach the threshold, it is possible that mobile phone A only appeared in the connectable range of the headset for a while and then left. Therefore, only based on the scanned target broadcast signal sent by mobile phone B, a backconnection is established with mobile phone B first and only; thereby ensuring the timeliness of the backconnection and the reliability of the backconnection, reducing the probability of invalid backconnection and the time consumption caused by invalid backconnection.

[0122] Exemplarily, when the headset is unboxed, it sends a communication connection signal to the first electronic device based on scanning the first target broadcast signal, or sends a communication connection signal to the second electronic device based on scanning the second target broadcast signal, and establishes a communication connection with the first electronic device or the second electronic device respectively. When the headset has established a paired connection with multiple electronic devices, the first electronic device and the second electronic device are two of the multiple electronic devices. When the headset scans the first target broadcast signal or the second target broadcast signal, it can only establish a back connection with one of the two electronic devices, or establish a back connection with the two electronic devices respectively based on the status of the scanned target signal.

[0123] like Figure 8 As shown, in the headset setting display interface of the electronic device (mobile phone B), the dual-device connection control interface highlights two devices connected to the headset (mobile phone A and mobile phone B, with mobile phone B being the priority connection), and other connected devices can also be displayed at the same time, but the grayscale display indicates that the other connected devices are currently not connected, such as Figure 8The tablet iPad shown in.

[0124] It should be noted that after the headset successfully reconnects to the electronic device, the headset can clear the time node recorded during the reconnection or the recorded number of scans and other information; or after a connection ends, that is, the headset is disconnected from the electronic device and returns to the off-box state, the headset can clear the time node recorded during the last reconnection or the recorded number of scans and other information; and start re-recording when the target broadcast signal is scanned in the off-box state next time.

[0125] Through the above method, the headset does not need to establish a reconnection with the connectible electronic device based on the inherent connection order in the historical connection information. In order to reduce the probability of prolonged reconnection time due to electronic devices with uncertain status, the electronic device to be connected with priority can be determined based on the status of the target broadcast signal scanned in the closed box state, thereby improving the timeliness and reliability of the reconnection between the headset and the electronic device.

[0126] Based on the implementation method of the above-mentioned embodiment one and embodiment two, the headset acts as a scanning end, wakes up regularly to scan for a period of time at a first scanning frequency. If the target broadcast signal is not scanned at the first scanning frequency, the scanning frequency is lowered, or the duration of a scan is shortened, and the scanning is continued at a second scanning frequency after the frequency is lowered or the scanning time period with the duration of a scan shortened, so as to save power consumption of the headset.

[0127] Then, the process of connecting the headset to the electronic device by using the headset as the broadcasting end and the electronic device as the scanning end is introduced.

[0128] Embodiment 3

[0129] like Figure 5 As shown, the headset connection system includes a headset and a first electronic device (hereinafter described by taking mobile phone B as an example). Among them, when the headset is in a closed state, it sends a first target broadcast signal at a third broadcast frequency, for example, a first target broadcast signal of low-power Bluetooth is sent every 10 seconds; the target broadcast signal may include a device identification of the headset, such as the model or name of the headset. After mobile phone B is disconnected from the headset, it periodically wakes up the scanning mechanism at the third scanning frequency and continuously scans the broadcast signal for a certain period of time; for example, when the first electronic device is disconnected from the headset, it wakes up the scanning mechanism every 20 minutes and scans for 15 seconds.

[0130] Exemplarily, when mobile phone B scans the target broadcast signal of the headset at the third scanning frequency, it increases the scanning frequency, wakes up the scanning mechanism periodically at the fourth scanning frequency, and continues scanning. When the headset is opened and sends out an opening broadcast signal, mobile phone B can quickly scan the opening broadcast signal, promptly discover the opening status of the headset, actively send a communication connection signal to the headset, initiate a reconnection request to the headset, and after the communication connection is established, the headset feeds back the successful reconnection information to mobile phone B, and then starts to enter the service state.

[0131] In one possible implementation, the headset is in a closed state and emits a third target broadcast signal including a third encryption protocol at a third broadcast frequency; after the first electronic device scans the third target broadcast signal, the first electronic device sends a communication connection signal to the headset based on the third encryption protocol when it scans the open broadcast signal, thereby establishing a communication connection with the headset.

[0132] Exemplarily, similar to Embodiment 1 and Embodiment 2, the target broadcast signal broadcast by the headset is also an encrypted broadcast signal containing an encryption protocol. After scanning the target broadcast signal, the electronic device can determine that the headset is within a connectable range and increase the scanning frequency to promptly detect the unboxing broadcast signal emitted by the headset when the box is opened, and quickly and actively establish a backconnection with the headset.

[0133] Exemplarily, the third encryption protocol contained in the third target broadcast signal may be an encryption protocol generated when the headset is paired and connected with the electronic device for the first time, that is, the headset may broadcast a third target broadcast signal containing the third encryption protocol, so that the first electronic device can distinguish other scanned broadcast signals. Only after scanning the third target broadcast signal containing the third encryption protocol, the first electronic device determines that the connectable headset is nearby, and after the headset is opened, responds based on the scanned opening broadcast signal, and actively initiates a connection back to the headset.

[0134] It should be noted that when mobile phone A is in a scanning state, the implementation principle is the same as that of mobile phone B, that is, the above-mentioned reconnection mechanism also applies to mobile phone A. The first electronic device can also be an electronic device that ranks first in the connection order in the historical connection information. After mobile phone A scans the target broadcast signal sent by the headset in the closed box state, it increases the scanning frequency, and after scanning the headset's open box broadcast signal, it actively establishes a reconnection with the headset; and when the target broadcast signal of mobile phone B is not scanned, after mobile phone A successfully establishes a reconnection with the headset, the headset will no longer try to reconnect to mobile phone B. After successfully reconnecting with mobile phone A, it directly enters the working state without the need to judge the reconnection with mobile phone B again; since mobile phone B is not involved in the scanning process, mobile phone B will naturally not actively initiate a reconnection request; the reconnection time between the headset and the electronic device is shortened, and the reconnection efficiency between the headset and the electronic device is improved. That is, no matter whether the electronic device that performs the scanning action is the first or the last electronic device in the original inherent connection sequence, when only one electronic device scans the target broadcast signal in the headset closed state, only this one electronic device can actively initiate a reconnection request to the headset, and after the reconnection is successful, it can enter the service state without determining the reconnection state of the other electronic device. Figure 7 As shown, in the headset setting display interface of the electronic device (mobile phone B), the dual-device connection control interface only displays one device connected to the headset; or as shown in FIG. Figure 8 As shown, the headset has established a paired connection with multiple electronic devices for the first time. When reconnecting, only one device (mobile phone B) that has established a communication connection with the headset can be highlighted, 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 grayscale to indicate that they are currently not connected.

[0135] Through the above method, after the first electronic device scans the third target broadcast signal of the headset based on the third scanning frequency, it increases the scanning frequency and continues to scan at the fourth scanning frequency, so that when the headset is opened, the headset's box opening broadcast signal can be scanned more promptly, and a communication connection signal can be sent to the headset in time to quickly establish a reconnection with the headset, without the need to judge the dual-connected devices each time the reconnection is performed and increase the reconnection time.

[0136] Embodiment 4

[0137] like Figure 6 As shown, the headset connection system may also include a headset, a first electronic device and a second electronic device; wherein, after the second electronic device is disconnected from the headset, it may also scan the target broadcast signal emitted by the headset in the closed state based on low-power Bluetooth, and the target broadcast signal may include an encryption protocol and a device identification of the headset, such as the model or name of the headset. The following is an example of the first electronic device being mobile phone B and the second electronic device being mobile phone A.

[0138] In one possible implementation, the headset is in a closed state and sends a third target broadcast signal containing an expected connection sequence at a third broadcast frequency; the first electronic device and the second electronic device scan the third target broadcast signal and, after the headset is opened, send a communication connection signal to the headset based on the expected connection sequence to establish communication connections with the headset respectively.

[0139] Exemplarily, for dual-connected headphones, the third target broadcast signal containing the third encryption protocol may also carry the expected connection order of the headphones. The expected connection order may be set based on the user's time habits or scenarios when using the headphones. For example, when the headphones and the electronic device are paired for the first time or when the electronic device and the headphones are in a connected state, the expected connection order of the headphones may be set based on the electronic device, so that the headphones receive the information of the expected connection order transmitted by the electronic device and set it according to the corresponding time or scene; thereby, when the box is turned off, the headphones may send a target broadcast signal with the expected connection order based on the corresponding time or scene.

[0140] Exemplarily, after scanning the target broadcast signal broadcast by the headset, the electronic device can also identify the expected connection sequence in the target broadcast signal, and establish a back connection with the headset based on the expected connection sequence after scanning the box opening broadcast signal.

[0141] Exemplarily, the expected connection sequence may include identifications of one or two devices to be connected.

[0142] like Figure 6 As shown, in the first case, when the expected connection sequence includes an identifier of a device to be connected, when the electronic device corresponding to the identifier scans the target broadcast signal, it quickly establishes a reconnection with the headset based on the expected connection sequence, and the headset no longer waits for another electronic device to reconnect, but directly enters a working state with the electronic device that has successfully reconnected; thereby improving the efficiency of the reconnection between the headset and the electronic device.

[0143] like Figure 6 As shown, 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 accompanied by serial numbers indicating the order of connection; when the electronic device scans the target broadcast signal and identifies the serial numbers of the sequential connection in the target broadcast signal, it establishes a backconnection to the headset in sequence based on the serial numbers in the expected connection sequence; after receiving the box opening broadcast signal, the electronic device with the first serial number actively initiates a backconnection to the headset based on the expected connection sequence in the target broadcast signal.

[0144] Exemplarily, if mobile phone B is the one that prioritizes establishing a communication connection in the expected connection sequence, then after scanning the headset box opening broadcast signal, mobile phone B will actively reconnect to the headset based on the expected connection sequence, and receive the successful reconnection information fed back by the headset; at the same time, the headset will initiate a reconnection to mobile phone A, and after receiving the successful reconnection information fed back by mobile phone A, it will start to enter the service state; or after the headset feeds back the successful reconnection information to mobile phone B, it feeds back the successful reconnection information to mobile phone A, and mobile phone A then actively initiates a reconnection request to the headset, and after the reconnection is successfully established, the headset feeds back the successful reconnection information to mobile phone A and enters the service state.

[0145] It should be noted that the above-mentioned fourth embodiment only represents an application scenario of dual connection that may be realized; for the headset storing the expected connection order and emitting low-power Bluetooth broadcast in the closed state, the reconnection mechanism. The expected connection order in the reconnection mechanism can be set and stored based on the use time or application scenario when the electronic device and the headset are connected. For example, during the morning driving time to work, the headset only needs to be connected to one electronic device (such as mobile phone B). Based on the above reconnection mechanism, the target broadcast signal with the expected connection order emitted by the headset can only contain the device identification information of mobile phone B; if you return home from get off work in the evening, when the user uses the headset, it may be necessary to connect two electronic devices, a tablet and a mobile phone, at the same time. The target broadcast signal with the expected connection order emitted by the headset can contain the device identification of the mobile phone and the tablet and sort them, such as the mobile phone is connected first, and the tablet is connected later; corresponding to this time period, the headset and the electronic device can be quickly reconnected based on the above reconnection mechanism.

[0146] Through the above method, there is no need to judge the dual-device reconnection status every time the headset reconnects to the electronic device. The expected connection order of the headset reconnection can be preset in advance, and the headset and the electronic device can be quickly reconnected in an appropriate application scenario or time period, thereby reducing the probability of invalid reconnection, improving the reconnection efficiency of the headset and the device, and enhancing the user experience.
