Description

Technical Field

[0001] This application relates to the field of Bluetooth headset technology, and in particular to a method for selecting a Bluetooth headset antenna and a Bluetooth headset. Background Technology

[0002] As the Bluetooth headset market continues to develop, users' demands for the Bluetooth headset experience are constantly increasing. While pursuing high-quality sound, they also want to improve the stability of the connection between the Bluetooth headset and the mobile phone signal. To ensure that Bluetooth headsets do not experience stuttering, multi-antenna designs are considered in the antenna layout, which involves antenna selection. Currently, most multi-antenna Bluetooth headsets on the market rely on overly simplistic antenna selection criteria. However, due to complex and changing environments, and the influence of many uncertain factors such as the different placement of the Bluetooth headset and mobile phone, a single selection criterion leads to frequent switching between antennas, increasing the probability of stuttering and reducing the user experience. Summary of the Invention

[0012] If the interference environment is a strong interference environment, then the first antenna is determined to be a working antenna;

[0013] If the interference environment is a weak interference environment, then based on the signal strength change amplitude of the Bluetooth headset, one of the first antenna and the second antenna is determined to be the working antenna.

[0014] The Bluetooth headset includes a left earpiece and a right earpiece. After determining that the interference environment in which the Bluetooth headset is located is a strong interference environment and determining that the first antenna is a working antenna, the method further includes:

[0015] Obtain the packet loss rate of the left earphone and the packet loss rate of the right earphone;

[0016] If the packet loss rate of the right earphone is greater than that of the left earphone, then the left earphone is determined to be the main earphone.

[0017] Alternatively, if the packet loss rate of the right earphone is less than that of the left earphone, then the right earphone is determined to be the main earphone.

[0018] The step of determining one of the first antenna and the second antenna as the working antenna based on the signal strength variation amplitude of the Bluetooth headset includes:

[0020] If the signal strength change of the Bluetooth headset is less than a second preset value, then one of the first antenna and the second antenna is determined to be the working antenna based on the motion state of the Bluetooth headset.

[0021] The motion state of the Bluetooth headset includes a moving state and a stationary state. The step of determining one of the first antenna and the second antenna as the working antenna based on the motion state of the Bluetooth headset includes:

[0022] If the Bluetooth headset is in a moving state, then the first antenna is determined to be a working antenna.

[0023] If the Bluetooth headset is in a stationary state, then the second antenna is determined to be a working antenna.

[0024] The Bluetooth headset includes a left earpiece and a right earpiece connected via Bluetooth. The step of determining which of the first antenna and the second antenna is the working antenna based on the motion state of the Bluetooth headset further includes:

[0025] Obtain the relationship between the signal strength of the left earphone and the signal strength of the right earphone;

[0026] The motion scene is determined based on the relationship between the signal strength of the left earphone and the signal strength of the right earphone, and the motion state of the Bluetooth earphone.

[0027] Based on the motion scenario, one of the first antenna and the second antenna is determined to be the working antenna;

[0028] Based on the described motion scenario, one of the left and right earphones is determined to be the main earphone.

[0029] The step of determining the motion scene based on the relationship between the signal strength of the left earphone and the signal strength of the right earphone, and the motion state of the Bluetooth earphones, includes:

[0030] If the difference between the signal strength of the right earphone and the signal strength of the left earphone is greater than a third preset value, and the Bluetooth earphone is in a moving state, then the motion scenario is determined to be the first scenario.

[0031] If the difference between the signal strength of the left earphone and the signal strength of the right earphone is greater than the third preset value, and the Bluetooth earphone is in a moving state, then the motion scenario is determined to be the second scenario.

[0032] If the absolute value of the difference between the signal strength of the left earphone and the signal strength of the right earphone is less than a fourth preset value, and the Bluetooth earphone is in a stationary state, then the motion scenario is determined to be the third scenario.

[0033] Prior to the step of determining one of the left and right earphones as the main earphone based on the sports scenario, the method includes: obtaining a preset main earphone of the Bluetooth earphone;

[0034] The steps of determining one of the first antenna and the second antenna as the working antenna based on the motion scenario, and determining one of the left earphone and the right earphone as the main earphone based on the motion scenario, include:

[0035] In response to the motion scenario being the first scenario, the first antenna is determined to be a working antenna, and the right earphone is determined to be the main earphone;

[0037] In response to the motion scenario being a third scenario, the second antenna is determined to be a working antenna, and the preset main earphone is determined to be the main earphone.

[0038] The Bluetooth headset includes a left and a right earpiece connected via Bluetooth. Following the step of confirming the second antenna as a working antenna in response to a signal strength change in the Bluetooth headset being greater than or equal to a first preset value, the method further includes:

[0039] Obtain the signal strength of the left earphone and the signal strength of the right earphone;

[0040] If the difference between the signal strength of the left earphone and the signal strength of the right earphone is greater than a fifth preset value, then the left earphone is determined to be the main earphone.

[0041] If the difference between the signal strength of the right earphone and the signal strength of the left earphone is greater than the fifth preset value, then the right earphone is determined to be the main earphone.

[0042] After the step of obtaining the wearing status of the Bluetooth headset, the method further includes:

[0043] If the Bluetooth headset is not worn by the user, then the first antenna is determined to be a working antenna.

[0044] The first antenna is a close-range antenna, and the second antenna is a long-range antenna.

[0045] To address the aforementioned technical problems, this application also provides a Bluetooth headset, including a first antenna, a second antenna, an accelerometer, and a control module. The control module is connected to the first antenna, the second antenna, and the accelerometer, respectively, and is used to execute the method described above.

[0046] The beneficial effects of this application are as follows: Unlike existing technologies, this application proposes a multi-antenna selection method based on intelligent scene determination in Bluetooth headset products. The Bluetooth headset antenna selection method provided in this application is applied to Bluetooth headsets, where the Bluetooth headset includes a first antenna and a second antenna. The method includes: obtaining the wearing status of the Bluetooth headset; in response to the Bluetooth headset being worn on the user's ear, obtaining the packet loss rate of the Bluetooth headset; determining the interference environment of the Bluetooth headset based on the packet loss rate; and then determining one of the first and second antennas as the working antenna based on the interference environment of the Bluetooth headset. By determining whether the user is wearing the Bluetooth headset, and when the Bluetooth headset is worn on the user's ear, the working antenna of the Bluetooth headset is selected based on the packet loss rate of the Bluetooth headset. This avoids switching the working antenna of the Bluetooth headset when it is not worn on the user's ear, reducing power consumption and preventing abnormal stuttering caused by frequent switching of the working antenna, ensuring the stability of the Bluetooth experience and leveraging the application capabilities of multiple antennas.

[0060] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0061] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0062] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0063] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, "many" in this application means two or more. Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0064] The Bluetooth headset antenna selection method provided in this application embodiment is applied to the antenna selection of a multi-antenna Bluetooth headset, which includes a first antenna and a second antenna.

[0065] The first antenna can be a close-range antenna, which refers to the antenna used by the Bluetooth headset in close-range scenarios when it connects to a terminal. Terminals include, but are not limited to, mobile phones or tablets. The first antenna has low free-space efficiency, high head-mount efficiency, and better anti-interference performance at close range, but its range is short and its wall-penetrating ability is poor. For example, if the Bluetooth headset is worn on the user's ear and the terminal is located on the user's body, the Bluetooth headset establishes a connection with the terminal through the first antenna.

[0066] The second antenna can be a long-range antenna, which refers to the antenna used by the Bluetooth headset in long-distance usage scenarios when connecting to the terminal. Secondary antennas offer advantages such as high free-space efficiency, low head-mount efficiency, strong external radiation capability, long range, and good wall-penetrating performance, but poor close-range anti-interference performance. They are mainly used in long-range and wall-penetrating scenarios. For example, the Bluetooth headset is worn on the user's ear, and the terminal is not located on the user (e.g., the user is wearing the Bluetooth headset in a room, and the terminal is in the living room), the Bluetooth headset establishes a connection with the terminal through the second antenna.

[0067] Please see Figure 1 , Figure 1This is a flowchart illustrating an embodiment of the method provided in this application. The method for selecting a Bluetooth headset antenna provided in this application specifically includes the following steps:

[0068] S1: Get the wearing status of the Bluetooth headset.

[0069] The Bluetooth headset can be worn on the user's ear or not. When the Bluetooth headset is not worn on the user's ear, the working antenna of the Bluetooth headset does not need to be selected and switched, thus reducing the power consumption of the Bluetooth headset.

[0070] In one embodiment, when the Bluetooth headset is powered on, it defaults to selecting the first antenna from the first and second antennas as the working antenna. This means the first antenna is the default working antenna for the Bluetooth headset, satisfying most common scenarios. When the Bluetooth headset is not worn on the user's ears, the first antenna is determined to be the working antenna, eliminating the need to switch antennas and reducing power consumption.

[0071] If the Bluetooth headset is worn on the user's ear, that is, the Bluetooth headset is worn on the user's ear, then proceed to step S2.

[0072] S2: In response to the Bluetooth headset being worn on the user's ear, obtain the packet loss rate of the Bluetooth headset.

[0073] In response to the Bluetooth headset being worn by the user's ear, the packet loss rate of the Bluetooth headset is obtained. The packet loss rate of the Bluetooth headset refers to the probability of data loss during data transmission between the Bluetooth headset and the terminal. The packet loss rate of the Bluetooth headset is related to the connection distance between the Bluetooth headset and the terminal, the presence of signal obstacles in the environment where the Bluetooth headset is located, and the presence of interference.

[0074] S3: Determine the interference environment of the Bluetooth headset based on the packet loss rate, and determine one of the first antenna and the second antenna as the working antenna based on the interference environment of the Bluetooth headset.

[0075] Since the packet loss rate of Bluetooth headsets is related to the interference environment of Bluetooth headsets, the interference environment of Bluetooth headsets is determined based on the packet loss rate, and one of the first antenna and the second antenna is determined as the working antenna based on the interference environment of Bluetooth headsets.

[0076] For example, the interference environment of the Bluetooth headset can be determined based on its packet loss rate, classifying it as a strong or weak interference environment. Strong interference environments include, but are not limited to, densely populated areas such as train stations, while weak interference environments include, but are not limited to, open, less crowded outdoor environments.

[0077] When the Bluetooth headset is in a highly interference-prone environment, the packet loss rate is relatively high. In such cases, the first antenna can be selected directly to improve the stability of signal transmission between the Bluetooth headset and the mobile phone. As mentioned earlier, the first antenna is the default working antenna when the Bluetooth headset is powered on. Therefore, in response to a highly interference-prone environment, the working antenna can remain unchanged, directly maintaining the first antenna as the working antenna, thus reducing the power consumption of switching the working antenna.

[0078] When the Bluetooth headset is in a weak interference environment, other information about the Bluetooth headset can be obtained, such as the signal strength and motion status of the Bluetooth headset, to select the first and second antennas of the Bluetooth headset and improve the accuracy of the selection of the working antenna of the Bluetooth headset.

[0079] Therefore, this embodiment proposes that the first or second antenna can be selected as the working antenna based on the wearing status and packet loss rate of the Bluetooth headset to improve the performance of the Bluetooth headset. When it is determined that the working antenna of the Bluetooth headset is the same as the default working antenna, the working antenna is not switched, reducing power consumption. At the same time, adding judgment conditions improves the accuracy of determining the working antenna, avoiding frequent switching of the Bluetooth headset's antenna due to a single judgment condition, which could cause abnormal stuttering in the Bluetooth headset. This ensures the stability of Bluetooth for the user experience and also leverages the application capabilities of multiple antennas.

[0080] When the Bluetooth headset is not worn by the user, the default operating antenna is directly selected as the headset's current operating antenna, avoiding the possibility of switching the operating antenna when the headset is not in use, which would increase power consumption. Only when the Bluetooth headset is worn by the user does the packet loss rate of the headset become available. Based on the packet loss rate, the interference environment in which the headset is located is determined, and then one of the first and second antennas is selected as the operating antenna. This improves the efficiency of determining the operating antenna and enhances the user experience.

[0081] Please see Figure 2 , Figure 2 This is a flowchart illustrating an embodiment of step S3 of this application. Step S3 includes the following specific steps:

[0082] S21: Compare the packet loss rate of the Bluetooth headset with the preset packet loss rate.

[0083] The Bluetooth headset includes a control module, which is connected to a first antenna and a second antenna. When the Bluetooth headset is worn on a user's ear, the control module further acquires the packet loss rate of the Bluetooth headset and compares it with a preset packet loss rate. If the packet loss rate of the Bluetooth headset is greater than the preset packet loss rate, the process proceeds to steps S22-S23; if the packet loss rate of the Bluetooth headset is less than or equal to the preset packet loss rate, the process proceeds to steps S24-S25.

[0084] S22: If the packet loss rate of the Bluetooth headset is greater than the preset packet loss rate, then the interference environment in which the Bluetooth headset is located is determined to be a strong interference environment.

[0085] If the packet loss rate of the Bluetooth headset exceeds a preset packet loss rate, the interference environment in which the Bluetooth headset operates is determined to be a strong interference environment. For example, if the preset packet loss rate is 30%, and the packet loss rate of the Bluetooth headset exceeds 30%, it means that more than 30% of the data was not successfully transmitted during data transmission. This will lead to a decrease in the performance of the Bluetooth headset, such as playback delay, thus affecting the user experience. Therefore, when the packet loss rate exceeds 30%, the control module determines that the interference environment in which the Bluetooth headset operates is a strong interference environment. In other embodiments, the preset packet loss rate can be other values, which can be set by the user, and this application does not impose any restrictions on this.

[0086] S23: In response to the interference environment being a strong interference environment, the first antenna is determined to be the working antenna.

[0087] If the packet loss rate of the Bluetooth headset exceeds the preset packet loss rate, the control module determines that the interference environment in which the Bluetooth headset is located is a strong interference environment, and then determines the first antenna as the working antenna. The default working antenna of the Bluetooth headset is the first antenna, so there is no need to switch the working antenna, thus reducing power consumption; by selecting the first antenna, the quality of the connection signal between the terminal and the Bluetooth headset can be improved.

[0088] S24: If the packet loss rate of the Bluetooth headset is less than or equal to the preset packet loss rate, then the interference environment in which the Bluetooth headset is located is determined to be a weak interference environment.

[0089] If the packet loss rate of the Bluetooth headset is less than or equal to a preset packet loss rate, the interference environment in which the Bluetooth headset is located is determined to be a weak interference environment. For example, if the preset packet loss rate is 30%, and the packet loss rate of the Bluetooth headset is less than or equal to 30%, it indicates that the data transmission between the terminal and the Bluetooth headset is normal, and the interference environment in which the Bluetooth headset is located is determined to be a weak interference environment.

[0090] S25: In response to the weak interference environment, obtain the signal strength change amplitude of the Bluetooth headset and determine one of the first antenna and the second antenna as the working antenna.

[0091] If the packet loss rate of the Bluetooth headset is less than or equal to the preset packet loss rate, and the control module determines that the interference environment in which the Bluetooth headset is located is a weak interference environment, the control module will continue to acquire the signal strength change amplitude of the Bluetooth headset, add judgment conditions, and judge whether to select the first antenna or the second antenna as the working antenna. This improves the accuracy of determining the working antenna of the Bluetooth headset, avoids frequent switching of the Bluetooth headset's antenna, and prevents abnormal stuttering of the Bluetooth headset, thus ensuring the stability of Bluetooth for the user experience.

[0092] Understandably, after the Bluetooth headset is powered on, the control module can continuously receive parameters from the Bluetooth headset, such as the real-time packet loss rate and the real-time signal strength. When additional judgment conditions need to be added, the control module can directly use the required parameters for judgment without waiting to acquire them, thus improving the response efficiency of the control module.

[0093] Therefore, the control module can obtain the signal strength change amplitude of the Bluetooth headset by acquiring the real-time signal strength changes of multiple Bluetooth headsets previously acquired by the control module.

[0094] Optional, please refer to Figure 3 , Figure 3 This is a flowchart illustrating an embodiment of step S23 of this application. The Bluetooth headset includes a left earphone and a right earphone connected via Bluetooth. The left earphone has a first antenna and a second antenna, and the right earphone also has a first antenna and a second antenna. That is, when the first antenna is determined to be the working antenna in step S23, the first antenna of the left earphone and the first antenna of the right earphone are both determined to be the working antenna.

[0095] Furthermore, the left earphone has a corresponding packet loss rate, and the right earphone also has a corresponding packet loss rate. After the control module selects the first antenna as the working antenna in step S23, the method provided in this embodiment further includes the following steps:

[0096] S31: Get the packet loss rate of the left earphone and the packet loss rate of the right earphone.

[0097] In this process, after the control module selects the first antenna of the Bluetooth headset as the working antenna, the control module can further obtain the packet loss rate of the left headset and the packet loss rate of the right headset.

[0098] It is understood that since the Bluetooth headset includes a left earpiece and a right earpiece, the packet loss rate of the Bluetooth headset obtained in step S2 can be the average of the packet loss rate of the left earpiece and the packet loss rate of the right earpiece, or the smaller value of the packet loss rate of the left earpiece and the packet loss rate of the right earpiece, etc., and this application does not limit it in this way.

[0099] Since step S22 has already obtained that the packet loss rate of the Bluetooth headset is greater than the preset packet loss rate, that is, at this time the packet loss rate of the left headset and the packet loss rate of the right headset obtained by the control module are both greater than the preset packet loss rate.

[0100] As mentioned above, after the Bluetooth headset is powered on, the control module obtains the packet loss rate of the Bluetooth headset in real time, including the packet loss rate of the left earphone and the packet loss rate of the right earphone. The acquisition of the packet loss rate of the left earphone and the packet loss rate of the right earphone should be directly extracted by the module storing parameters of the Bluetooth headset, thereby improving the processing efficiency of the control module.

[0101] Furthermore, the control module can compare the packet loss rate of the left earphone and the packet loss rate of the right earphone. If the control module determines that the packet loss rate of the left earphone is greater than that of the right earphone, it proceeds to step S32; if the control module determines that the packet loss rate of the right earphone is greater than that of the left earphone, it proceeds to step S33.

[0102] S32: In response to the left earphone's packet loss rate being greater than the right earphone's packet loss rate, determine that the right earphone is the master earphone.

[0103] Specifically, when the control module responds to the left earphone's packet loss rate being greater than the right earphone's packet loss rate, it determines the right earphone as the master earphone. That is, the right earphone is used to receive data transmitted from the terminal to the Bluetooth earphone, and then the right earphone transmits the data to the left earphone. Since the right earphone's packet loss rate is lower than the left earphone's packet loss rate, it can improve the efficiency of data transmission, ensure the performance of the Bluetooth earphone, and improve the user experience.

[0104] S33: In response to the packet loss rate of the right earphone being greater than that of the left earphone, determine that the left earphone is the master earphone.

[0105] When the control module responds to the right earpiece's packet loss rate being greater than the left earpiece's packet loss rate, it determines the left earpiece as the master earpiece to ensure efficient data transmission.

[0106] It is understood that since the Bluetooth headset includes a left and a right earpiece, the determination of the first antenna of the Bluetooth headset as a working antenna as described in this application means determining the first antenna of the left earpiece as a working antenna and the first antenna of the right earpiece as a working antenna. Similarly, determining the second antenna of the Bluetooth headset as a working antenna means determining the second antenna of the left earpiece as a working antenna and the second antenna of the right earpiece as a working antenna.

[0107] Optionally, please refer to Figure 4 , Figure 4 This is a flowchart illustrating an embodiment of step S25 of this application. After the control module responds to the fact that the interference environment in which the Bluetooth headset is located is a weak interference environment and obtains the signal strength change amplitude of the Bluetooth headset, the method provided in this application embodiment further includes the following specific steps:

[0108] S41: In response to the signal strength change amplitude of the Bluetooth headset being less than the second preset value, one of the first antenna and the second antenna is determined as the working antenna based on the motion state of the Bluetooth headset.

[0109] The signal strength of the Bluetooth headset represents the strength of the connection signal between the headset and the terminal (e.g., a mobile phone). When the signal strength is high, the connection is considered strong, indicating the terminal is being carried by the user. In this case, the first antenna can be selected as the working antenna to improve the connection quality. Conversely, when the signal strength is low, the connection is considered weak, indicating the phone is not being carried by the user and there is a distance between the headset and the terminal. In this case, the second antenna can be selected to improve the stability of the connection.

[0110] The signal strength variation of the Bluetooth headset indicates the stability of the connection between the headset and the terminal. When the control module detects a signal strength variation less than a first preset value, it indicates a stable connection between the headset and the terminal. The control module can further acquire the headset's motion status, adding more criteria for judgment and improving the efficiency of determining the headset's operating antenna.

[0111] In one embodiment, the second preset value can be 5dB, meaning that when the signal strength variation of the Bluetooth headset is less than 5dB, the connection signal between the Bluetooth headset and the terminal is considered stable. In other embodiments, the second preset value can also be other values, and this application does not limit it.

[0112] The motion state of the Bluetooth headset includes a moving state and a stationary state. When the Bluetooth headset is in a moving state, proceed to step S42; when the Bluetooth headset is in a stationary state, proceed to step S43.

[0113] S42: In response to the Bluetooth headset being in a moving state, the first antenna is determined to be the working antenna.

[0114] In one embodiment, the Bluetooth headset may include an accelerometer sensor, which is used to collect speed data of the Bluetooth headset, and then the control module can determine the motion state of the Bluetooth headset based on the speed data collected by the accelerometer sensor.

[0115] When the Bluetooth headset is in a mobile state, that is, when the user is moving while carrying the Bluetooth headset and the terminal, such as walking or running, the control module determines the first antenna as the working antenna to improve the connection quality between the Bluetooth headset and the terminal.

[0116] S43: If the Bluetooth headset is stationary, then the second antenna is determined to be the working antenna.

[0117] The "stationary state" of the Bluetooth headset indicates that the user wearing the headset is stationary, such as sitting or standing. The terminal may or may not be worn by the user. Since the user is stationary, the connection distance between the Bluetooth headset and the terminal remains essentially constant. Therefore, the second antenna is chosen as the working antenna to improve the stability of the connection between the Bluetooth headset and the terminal.

[0118] Alternatively, please continue reading Figure 5 , Figure 5 This is a flowchart illustrating another embodiment of the method provided in this application. After the control module acquires the motion state of the Bluetooth headset, the method provided in this application embodiment further includes the following specific steps:

[0119] S51: Obtain the relationship between the signal strength of the left earphone and the signal strength of the right earphone.

[0120] When the control module obtains the motion state of the Bluetooth headset and temporarily determines the working antenna of the Bluetooth headset, the control module further obtains the signal strength of the left headset and the signal strength of the right headset to increase the judgment conditions. By obtaining the magnitude relationship between the signal strength of the left headset and the signal strength of the right headset, the control module determines whether to maintain the selection of the working antenna in steps S42 and S43, and determines one of the left headset and the right headset as the main headset.

[0121] S52: Determine the motion scenario based on the relationship between the signal strength of the left and right earphones and the motion status of the Bluetooth earphones.

[0122] The signal strength of the left earpiece reflects the connection distance between the left earpiece and the terminal, while the signal strength of the right earpiece reflects the connection distance between the right earpiece and the terminal. Therefore, the control module can determine the connection distance relationship between the left and right earpieces and the terminal based on the relative strengths of their respective signal strengths. For example, if the signal strength of the left earpiece is greater than that of the right earpiece, it can be determined that the connection distance between the left earpiece and the terminal is less than that of the right earpiece, suggesting that the terminal may be placed on the user's left side. Conversely, if the signal strength of the right earpiece is greater than that of the left earpiece, it can be determined that the connection distance between the right earpiece and the terminal is less than that of the left earpiece, suggesting that the terminal is placed on the user's right side.

[0123] Furthermore, the control module can correlate the signal strength of the left earphone with that of the right earphone with the motion state of the Bluetooth earphones to determine the motion scenario of the Bluetooth earphones.

[0124] For example, when the control module determines that the signal strength of the left earphone is greater than that of the right earphone, it determines that the terminal is located on the user's left side and the Bluetooth earphone is in a moving state. Therefore, the control module can define the motion scenario as follows: the terminal is carried on the user's left side (possibly in the user's left hand or left pocket), and the user is moving, such as walking or running. This motion scenario, where the terminal is carried on the user's left side and the Bluetooth earphone is in a moving state, can be defined as the first scenario.

[0125] When the control module determines that the signal strength of the right earphone is greater than that of the left earphone, it determines that the terminal is located on the user's right side and the Bluetooth earphones are in a moving state. That is, the terminal is carried on the user's right side and the user is moving. This motion scenario, where the terminal is carried on the user's right side and the Bluetooth earphones are in a moving state, can be defined as the second scenario.

[0126] When the control module determines that the signal strength of the left earphone is basically the same as that of the right earphone, it determines that the terminal is in a centered position. This could be because the user is holding the terminal in front of them, or because the terminal is not being carried by the user and the distance between the user's left and right ears and the terminal is basically the same (e.g., the terminal is placed in front of the user and the user is looking at it). Further, if the control module determines that the Bluetooth earphones are stationary, then the control module can define the motion scenario as the terminal being in a centered position between the left and right earphones, and the user being stationary. This motion scenario, where the terminal is in a centered position and the Bluetooth earphones are stationary, can be defined as the third scenario.

[0127] S53: Based on the motion scenario, determine one of the first and second antennas as the working antenna, and one of the left and right earphones as the main earphone.

[0128] After determining the motion scenario in step S52, the control module can further determine the working antenna and main earphone of the Bluetooth headset based on the motion scenario.

[0129] Optional, please refer to Figure 6 , Figure 6 This is a flowchart illustrating steps S52 and S53 of the first embodiment of this application. In this embodiment, the specific steps of determining a motion scene, determining one of the first and second antennas as the working antenna based on the motion scene, and designating one of the left and right earphones as the main earphone include:

[0130] S61: If the difference between the signal strength of the right earphone and the signal strength of the left earphone is greater than a third preset value, and the Bluetooth earphone is in a moving state, then the motion scenario is determined to be the first scenario.

[0131] In one embodiment, the third preset value can be 15dB. When the control module responds to the difference between the signal strength of the right earphone and the signal strength of the left earphone being greater than 15dB, that is, the signal strength of the right earphone is significantly greater than the signal strength of the left earphone, it can be determined that the terminal is located on the right side, and the control module determines that the motion state of the Bluetooth earphone is a moving state, then the motion scenario is determined to be the first scenario.

[0132] S62: In response to the motion scene being the first scene, the first antenna is determined to be the working antenna, and the right earphone is determined to be the main earphone.

[0133] In the first scenario, the Bluetooth headset is in a moving state and the terminal is placed on the right side. Therefore, it can be determined that the first antenna is the working antenna. Since the first antenna has been determined to be the working antenna in step S42, there is no need to switch the working antenna here. It is sufficient to keep the first antenna as the working antenna.

[0134] With the terminal placed on the right, the connection signal between the right earphone and the terminal is more stable and the data reception efficiency is higher. Therefore, the control module selects the right earphone as the main earphone to improve the data reception efficiency of the Bluetooth earphone.

[0135] In other embodiments, the third preset value may be other specific settings, which can be set by the user, and this application does not limit this.

[0136] Optionally, such as Figure 7 As shown, Figure 7 This is a flowchart illustrating steps S52 and S53 of the second embodiment of this application. In this embodiment, the specific steps of determining the motion scene, determining one of the first and second antennas as the working antenna based on the motion scene, and selecting one of the left and right earphones as the main earphone further include:

[0137] S71: If the difference between the signal strength of the left earphone and the signal strength of the right earphone is greater than a third preset value, and the Bluetooth earphone is in motion state, then the motion scenario is determined to be the second scenario.

[0138] In the second scenario, the terminal is placed on the user's left side and the Bluetooth headset is in a moving state. Therefore, when the control module responds to the difference between the signal strength of the left headset and the signal strength of the right headset being greater than a third preset value, and the Bluetooth headset is in a moving state, the motion scenario is determined to be the second scenario.

[0139] S72: In response to the motion scene being the second scene, the first antenna is determined to be the working antenna, and the left earphone is determined to be the main earphone.

[0140] In the second scenario, the Bluetooth headset is in a moving state and the terminal is placed on the left side. Therefore, it can be determined that the first antenna is the working antenna. Since the first antenna has been determined to be the working antenna in step S42, there is no need to switch the working antenna here. It is sufficient to keep the first antenna as the working antenna.

[0141] With the terminal placed on the left, the signal strength of the left earphone is significantly greater than that of the right earphone. The connection signal between the left earphone and the terminal is more stable, and the data reception efficiency is higher. Therefore, the control module determines the first antenna as the working antenna and determines the left earphone as the main earphone, thereby improving the data reception efficiency of the Bluetooth earphone.

[0142] Optionally, such as Figure 8 As shown, Figure 8 This is a flowchart illustrating steps S52 and S53 of the third embodiment of this application. In this embodiment, the specific steps of determining the motion scene, determining one of the first and second antennas as the working antenna based on the motion scene, and determining one of the left and right earphones as the main earphone further include:

[0143] S81: If the absolute value of the difference between the signal strength of the left earphone and the signal strength of the right earphone is less than the fourth preset value, and the Bluetooth earphone is in a stationary state, then the motion scenario is determined to be the third scenario.

[0144] The fourth preset value can be 10dB. In other embodiments, the fourth preset value can also be other values, which can be set by the user according to their own needs. This application does not limit this. When the absolute value of the difference between the signal strength of the left earphone and the signal strength of the right earphone is less than the third preset value, that is, it means that the signal strength of the left earphone and the signal strength of the right earphone are not much different, it is determined that the terminal is placed in the center, and the terminal is not biased towards the left earphone (e.g., placed to the left of the user) and not biased towards the right earphone (e.g., placed to the right of the user). It can be considered that the connection distance between the left earphone and the mobile phone is equal to the connection distance between the right earphone and the mobile phone.

[0145] Furthermore, since the Bluetooth headset is stationary, the control module can determine the motion scenario as the third scenario.

[0146] S82: In response to the motion scene being the third scene, the second antenna is determined to be the working antenna, and the preset main earphone is determined to be the main earphone.

[0147] Since the Bluetooth headset is stationary, the control module can directly determine the second antenna as the working antenna and select the extended-pitch antenna to improve the signal strength between the phone and the Bluetooth headset. Since step S43 determines the second antenna as the working antenna, there is no need to switch the working antenna here; simply maintaining the second antenna as the working antenna is sufficient.

[0148] Since the terminal is placed in the center, the connection signals between the left and right earphones and the terminal are basically equal. Therefore, there is no need to switch the master-slave relationship between the left and right earphones. In one embodiment, when the Bluetooth earphone is powered on, it will select the preset master earphone as the master earphone for operation. For example, if the left earphone is the preset master earphone, the left earphone will operate as the master earphone after the Bluetooth earphone is powered on and before the master earphone is switched.

[0149] In other embodiments, the right earphone may be the preset main earphone. This application does not limit this and the user can set it himself.

[0150] Therefore, in this embodiment, before the control module determines which of the left and right earphones is the master earphone based on the motion scenario, the control module can obtain the preset master earphone of the Bluetooth earphone in advance. Then, after determining that the motion scenario is the third scenario, the control module directly determines the preset master earphone as the master earphone, without switching the master-slave relationship between the left and right earphones, thus reducing the power consumption of the Bluetooth earphone.

[0151] Understandably, since the Bluetooth headset has a preset master headset, in steps S32, S33, S62 and S72, if the determined master headset is the same as the preset master headset, the control module can directly maintain the preset master headset as the master headset, without switching the master-slave relationship between the left and right headsets, thus reducing the power consumption of the Bluetooth headset.

[0152] In other embodiments, if the absolute value of the difference between the signal strength of the left earphone and the signal strength of the right earphone is less than a third preset value, but the Bluetooth earphone is in a moving state, the control module can also maintain the preset main earphone as the main earphone and determine the first antenna as the working antenna.

[0153] If the control module responds to a signal strength difference between the left and right earphones that is greater than a third preset value, but the Bluetooth earphones are stationary, the control module can determine that the left earphone is the main earphone and that the second antenna is the working antenna.

[0154] The control module can flexibly process the signal strength and motion status of the Bluetooth headset, determine the motion scenario, and then determine one of the first and second antennas as the working antenna based on the motion scenario, and determine one of the left and right earphones as the main earphone, thereby improving the data reception efficiency of the Bluetooth headset and enhancing the user experience of the Bluetooth headset.

[0155] Optional, such as Figure 9 As shown, Figure 9This is a flowchart illustrating another embodiment of step S25 of this application. In step S23, after the control module obtains the signal strength change amplitude of the Bluetooth headset, the method provided in this application embodiment further includes the following steps:

[0156] S91: If the signal strength change of the Bluetooth headset is greater than or equal to a first preset value, then the second antenna is determined to be the working antenna.

[0157] Specifically, when the control module responds to a signal strength change in the Bluetooth headset exceeding a first preset value, indicating unstable connection between the Bluetooth headset and the terminal, it suggests a possible change in the distance between them. Therefore, when the control module responds to a signal strength change greater than or equal to the first preset value, it indicates that the distance between the Bluetooth headset and the terminal is gradually increasing, or that an obstacle has appeared. This could be due to the user moving away from the terminal or the user walking through a wall. In this case, the control module selects a second antenna as the operating antenna, employing a stretched antenna to improve the stability of the connection signal between the phone and the Bluetooth headset.

[0158] The first preset value can be 30dB. In other embodiments, the first preset value can also be set to other specific values.

[0159] Optionally, such as Figure 10 As shown, Figure 10 This is a flowchart illustrating an embodiment of step S91 of this application. After determining the second antenna as the working antenna in step S91 in response to the signal strength change amplitude of the Bluetooth headset being greater than or equal to a first preset value, the method provided in this embodiment further includes the following steps:

[0160] S101: Obtain the signal strength of the left earphone and the signal strength of the right earphone.

[0161] After the control module determines that the first antenna is the working antenna, the control module can further obtain the signal strength of the left earphone and the signal strength of the right earphone, and compare the signal strength of the left earphone and the signal strength of the right earphone. If the signal strength of the left earphone is greater than the signal strength of the right earphone, proceed to step S102; if the signal strength of the right earphone is greater than the signal strength of the left earphone, proceed to step S103.

[0162] S102: If the difference between the signal strength of the left earphone and the signal strength of the right earphone is greater than the fifth preset value, then the left earphone is determined to be the main earphone.

[0163] The fifth preset value can be 5dB. In other embodiments, the fifth preset value can also be other specific values.

[0164] When the control module responds to the difference between the signal strength of the left earphone and the signal strength of the right earphone being greater than the fifth preset value, that is, the signal strength of the left earphone is significantly greater than the signal strength of the right earphone, and the left earphone has higher data reception efficiency, the control module determines that the left earphone is the main earphone.

[0165] S103: If the difference between the signal strength of the right earphone and the signal strength of the left earphone is greater than the fifth preset value, then the right earphone is determined to be the main earphone.

[0166] When the control module responds to the difference between the signal strength of the right earphone and the signal strength of the left earphone being greater than the fifth preset value, that is, the signal strength of the right earphone is significantly greater than the signal strength of the left earphone, and the right earphone has higher data reception efficiency, the control module determines that the left earphone is the main earphone.

[0167] As can be seen from the preceding text, after the Bluetooth headset is powered on, a preset master headset is running. Therefore, when the master headset determined in steps S101 and S102 is the same as the preset master headset, the control module may not switch the master-slave relationship between the left and right headsets to reduce the power consumption of the Bluetooth headset.

[0168] In summary, the method provided in this application determines one of the first and second antennas as the working antenna based on the Bluetooth headset's wearing status, packet loss rate, signal strength, and motion state. This method incorporates more decision-making factors, avoiding abnormal stuttering caused by frequent antenna switching in complex and changing environments, ensuring Bluetooth stability for the user experience, and also leveraging the application capabilities of multiple antennas.

[0169] This application also provides a Bluetooth headset (not shown), including a first antenna, a second antenna, an accelerometer, and a control module. The control module is connected to the first antenna, the second antenna, and the accelerometer, respectively, and is used to perform the method described above.

[0170] Specifically, the control module can receive the wearing status of the Bluetooth headset, the packet loss rate of the Bluetooth headset to obtain the interference environment in which the Bluetooth headset is located, the signal strength of the Bluetooth headset, and further receive the sensing data of the accelerometer to obtain the motion status of the Bluetooth headset, etc., and then control the switching of the first antenna as the working antenna or the switching of the second antenna as the working antenna.
