Description

Technical Field

[0001] The present invention relates to the field of control technology of TWS Bluetooth headsets, and in particular to a TWS Bluetooth headset and a standby control method, system, and storage medium thereof. Background Art

[0002] Due to their limited battery capacity, TWS (True Wireless Stereo) Bluetooth headsets are usually equipped with a charging case to charge the headset and extend its usage time. Currently, most Bluetooth headsets on the market start charging when placed in the charging case. After charging is complete, the headset shuts down. The next time the user uses the headset, the charging case is opened, generating an electrical signal that is sent to the headset to wake it up and connect it to the device to be connected.

[0003] However, there is a prerequisite for waking up the Bluetooth headset by recognizing the box opening action, that is, the charging box must be in a powered state. This means that when the charging box is out of power but the Bluetooth headset is powered, the Bluetooth headset cannot be woken up, resulting in the Bluetooth headset being unable to be used normally, giving users a bad experience. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a TWS Bluetooth headset and its standby control method, system and storage medium, so as to solve the problem in the prior art that the Bluetooth headset cannot be used normally when the charging box has no power.

[0005] To achieve the above object, the first aspect of the present invention provides a standby control method for a TWS Bluetooth headset, which specifically includes the following steps:

[0006] monitoring in real time an action of inserting a Bluetooth headset into the charging box, and obtaining a first remaining power of the charging box when the Bluetooth headset is inserted;

[0007] determining whether the first remaining power reaches a preset low power threshold, and generating a standby instruction if the first remaining power reaches the low power threshold;

[0008] In response to the standby instruction, a standby pulse of a first preset frequency is generated, and the Bluetooth headset responds to the standby pulse and enters a low-power standby mode.

[0009] Furthermore, after the step of determining whether the first remaining power reaches a preset low power threshold, the following steps are further included:

[0010] If the low power threshold is not reached, obtaining a second remaining power of the Bluetooth headset;

[0011] determining whether the second remaining power is full, and generating a shutdown instruction if the second remaining power is full;

[0012] In response to the shutdown instruction, a shutdown pulse with a second preset frequency is generated, and the Bluetooth headset responds to the shutdown pulse and shuts down.

[0013] Furthermore, after the step of determining whether the second remaining power is full power, the following steps are further included:

[0014] If the second remaining power is not full power, generating a charging instruction;

[0015] In response to the charging instruction, the Bluetooth headset is charged.

[0016] Furthermore, after the step of charging the Bluetooth headset in response to the charging instruction, the method further includes the following steps:

[0017] Real-time monitoring of a first real-time power level of the charging box and a second real-time power level of the Bluetooth headset during the charging process;

[0018] Determine whether the first real-time power level reaches the low power threshold; if so, generate the standby instruction; otherwise, determine whether the second real-time power level is full; if so, generate the shutdown instruction; otherwise, continue to charge the Bluetooth headset and monitor the first real-time power level and the second real-time power level in real time.

[0019] Furthermore, after the step of generating a shutdown pulse of a second preset frequency in response to the shutdown instruction, and the Bluetooth headset responding to the shutdown pulse and shutting down, the method further includes the following steps:

[0020] monitoring the standby power level of the charging box in real time, and generating a power-on instruction and the standby instruction when the standby power level reaches a low power threshold;

[0021] In response to the power-on instruction, a power-on pulse of a third preset frequency is generated, and the Bluetooth headset responds to the power-on pulse and powers on;

[0022] In response to the standby instruction, a standby pulse of the first preset frequency is generated, and the Bluetooth headset responds to the standby pulse and enters a low-power standby mode.

[0023] Furthermore, after the step of generating a standby pulse of a first preset frequency in response to the standby instruction, and the Bluetooth headset responding to the standby pulse and entering the low-power standby mode, the method further includes the following steps:

[0024] The method monitors connection requests acting on the Bluetooth headset in real time, and counts the duration of the low-power standby mode of the Bluetooth headset according to a preset timing period from the time when the Bluetooth headset enters the low-power standby mode, and determines whether the Bluetooth headset receives the connection request and connects to the device to be connected within the preset timing period. If not, the shutdown instruction is generated at the end of the preset timing period.

[0025] Furthermore, the charging box has a first charging PIN and a second charging PIN for communicating with the Bluetooth headset, and when the charging box communicates with the Bluetooth headset, the output levels of the first charging PIN and the second charging PIN have two states, a first level and a second level. By switching the state of the first charging PIN and the second charging PIN between the first level and the second level, a corresponding pulse is sent to the Bluetooth headset.

[0026] A second aspect of the present invention provides a standby control system for a TWS Bluetooth headset, comprising:

[0027] An action monitoring module is used to monitor the Bluetooth headset insertion action on the charging box in real time;

[0028] A first power monitoring module is used to obtain and monitor a first remaining power, a first real-time power, and a standby power of the charging box when the Bluetooth headset is placed in the charging box, wherein the first remaining power is the current power of the charging box when the Bluetooth headset is placed in the charging box, the first real-time power is the real-time power of the charging box when the Bluetooth headset is charging, and the standby power is the standby power of the charging box after the Bluetooth headset is turned off;

[0033] A charging box having a built-in standby control system for a TWS Bluetooth headset, wherein the standby control system of the TWS Bluetooth headset implements the standby control method of the TWS Bluetooth headset as described above when running, so as to generate a standby pulse, a power-off pulse, and a power-on pulse in a timely manner; and

[0034] The Bluetooth headset electrically connected to the charging box is used to receive the standby pulse to enter a low-power standby mode, receive a shutdown pulse to shut down, or receive a power-on pulse to start up.

[0044] Example 1

[0045] like Figure 1As shown in the figure, it is a structural block diagram of a TWS Bluetooth headset of the present embodiment. The TWS Bluetooth headset of the present embodiment includes a charging box 101 and a Bluetooth headset 102 electrically connectable to the charging box 101. When the Bluetooth headset 102 is placed in the charging box 101 and connected to the charging box 101, the charging box 101 can charge the Bluetooth headset 102, and can also realize communication between the charging box 101 and the Bluetooth headset 102 when the Bluetooth headset 102 reaches the standby, shutdown or startup conditions, and generate a corresponding standby pulse with a first preset frequency, a shutdown pulse with a second preset frequency or a startup pulse with a third preset frequency and send it to the Bluetooth headset 102 to control the Bluetooth headset 102 to enter standby, shutdown or startup, so that when the charging box 101 has no power but the Bluetooth headset 102 has power, it can still be used normally, and the usage time of the Bluetooth headset 102 can be maximized.

[0046] The charging box 101 has a first charging PIN and a second charging PIN, and the corresponding Bluetooth headset 102 has a first connection PIN and a second connection PIN respectively provided on the first headset and the second headset of the Bluetooth headset 102 and connected to the first charging PIN and the second charging PIN respectively. When the Bluetooth headset 102 is placed in the charging box 101, the first charging PIN is connected to the first connection PIN, and the second charging PIN is connected to the second connection PIN, thereby realizing the charging of the Bluetooth headset 102 by the charging box 101 and the communication between the charging box 101 and the Bluetooth headset 102. It is understandable that in some other embodiments, the charging PIN and the connection PIN can be replaced by providing a metal shrapnel, a DC interface, etc., so as to realize the electrical connection between the charging box 101 and the Bluetooth headset 102.

[0047] In this embodiment, the output levels of the first charging PIN and the second charging PIN have two states, namely, a first level and a second level. When the Bluetooth headset 102 receives the standby pulse, the power-off pulse and the power-on pulse, it will trigger the output levels of the first charging PIN and the second charging PIN to switch between the first level and the second level, that is, switch between the first level and the second level according to the first preset frequency, the second preset frequency or the third preset frequency, so that the Bluetooth headset 102 receives and identifies the switching frequency of the first level and the second level, and then determines whether the pulse is a standby pulse of the first preset frequency, a power-off pulse of the second preset frequency or a power-on pulse of the third preset frequency, and when it is identified as a corresponding pulse, controls the Bluetooth headset 102 to enter a low-power standby mode, shut down or start up accordingly.

[0048] Specifically, the charging box 101 has a built-in control circuit 1011 and a first battery 1012 electrically connected to the control circuit 1011, a first fuel gauge 1013 and a charging circuit 1014.

[0049] The first battery 1012 is used to power the control circuit 1011 , the first fuel gauge 1013 and the charging circuit 1014 , and the first battery 1012 can be connected to an external power source via an electrical connector to charge the first battery 1012 .

[0050] The first power meter 1013 is also electrically connected to the first battery 1012 and is used to measure the power of the first battery 1012, wherein the power of the first battery 1012 includes the first remaining power of the first battery 1012 when the Bluetooth headset 102 is placed in the charging box 101, the first real-time power of the first battery 1012 during the charging process of the Bluetooth headset 102, and the standby power of the first battery 1012 after the Bluetooth headset 102 is on standby.

[0051] The control circuit 1011 is used to compare the first remaining power, the first real-time power, and the standby power with a preset low-power threshold, and when the first remaining power, the first real-time power, and the standby power reach the low-power threshold, generate a standby pulse of a first preset frequency and send it to the first earphone and the second earphone, so that the first earphone and the second earphone receive the standby pulse and enter a low-power standby mode. The control circuit 1011 is also used to generate a shutdown pulse of a second preset frequency or a power-on pulse of a third preset frequency and send it to the Bluetooth earphone 102 when the power level of the Bluetooth earphone 102 meets the shutdown or power-on conditions, so that the Bluetooth earphone 102 receives the shutdown pulse or the power-on pulse and turns on; and generate a charging instruction when the Bluetooth earphone 102 is placed in the charging box 101 and meets the charging conditions.

[0052] The charging circuit 1014 is also electrically connected to the first charging PIN and the second charging PIN, and is used to charge the first earphone and the second earphone of the Bluetooth headset 102 according to the charging instruction.

[0053] The first earphone of the Bluetooth headset 102 has a built-in second battery 1021 and a second fuel gauge 1022, and the second earphone of the Bluetooth headset 102 has a built-in third battery 1023 and a third fuel gauge 1024.

[0054] The second battery 1021 and the third battery 1023 are respectively used to power the first earphone and the second earphone of the Bluetooth headset 102. The second battery 1021 and the third battery 1023 are respectively electrically connected to the first connection PIN and the second connection PIN, and are used to charge the second battery 1021 and the third battery 1023 when the charging circuit 1014 is turned on.

[0055] The second fuel meter 1022 and the third fuel meter 1024 are electrically connected to the corresponding second battery 1021 and third battery 1023 respectively, and the second fuel meter 1022 and the third fuel meter 1024 are used to measure the power of the second battery 1021 and the third battery 1023 respectively, wherein the power of the second battery 1021 and / or the third battery 1023 includes the second remaining power of the second battery 1021 and / or the third battery 1023 when the Bluetooth headset 102 is placed in the charging box 101 and the second real-time power of the second battery 1021 and / or the third battery 1023 during the process of charging the Bluetooth headset 102 by the charging circuit 1014. In a specific implementation of this embodiment, when the power levels of the second battery 1021 and the third battery 1023 are equal, the second remaining power level and the second real-time power level are the power levels of the second battery 1021 or the third battery 1023; when the power levels of the second battery 1021 and the third battery 1023 are not equal, the second remaining power level and the second real-time power level are the smaller one of the second battery 1021 and the third battery 1023.

[0056] The control circuit 1011 is also used to compare the second remaining power and the second real-time power with the full power (i.e., 100%) of the second battery 1021 or the third battery 1023, and when the second remaining power and the second real-time power are full and the low-power standby mode is not triggered, generate a shutdown pulse of the second preset frequency and send it synchronously to the first earphone and the second earphone, so that the first earphone and the second earphone synchronously receive the shutdown pulse and shut down at the same time; and when the Bluetooth headset 102 is turned off and the low-power standby mode is triggered, first generate a power-on pulse of the third preset frequency and send it synchronously to the first earphone and the second earphone, so that the first earphone and the second earphone synchronously receive the power-on pulse and turn on at the same time, and then generate the standby pulse of the first preset frequency to synchronously control the first earphone and the second earphone to enter the low-power standby module at the same time.

[0057] The control circuit 1011 is further configured to generate the charging instruction to turn on the charging circuit 1014 to charge the second battery 1021 when the second remaining power is not full and the low-power standby mode is not triggered.

[0058] In this embodiment, the purpose of using the smaller battery power of the second battery 1021 and the third battery 1023 as the second remaining power and the second real-time power is to avoid the situation where the first earphone and the second earphone are not used synchronously, and the power of one earphone reaches full power in advance, triggering shutdown and causing the other earphone to be not fully charged, thereby preventing a time difference in the usage time of the two earphones when they are used synchronously later.

[0059] As a preferred method of this embodiment, the control module can also perform asynchronous control on the first earphone and the second earphone, that is, respectively compare the second battery 1021 and the third battery 1023 with the full charge, and control the charging circuit 1014 to charge the second battery 1021 and the third battery 1023 respectively according to the respective comparison results. When the battery of one earphone is fully charged, the earphone is triggered to shut down separately, while the other earphone continues to be charged. If the low-power standby mode is triggered when the other earphone is not fully charged, the earphone that has been turned off is triggered to turn on separately and both earphones are triggered to enter the low-power standby mode. In this way, when two earphones with a difference in charge are charged synchronously, the corresponding battery loss caused by overcharging of the earphone with more charge can be avoided.

[0060] The TWS Bluetooth headset of this embodiment monitors the power of the first battery 1012 of the charging box 101 and the power of the second battery 1021 of the Bluetooth headset 102 in real time by setting a first power meter 1013, a second power meter 1022 and a third power meter 1024, and comprehensively judges the status of the charging box 101 and the Bluetooth headset 102 through the control module, so that the charging box 101 generates a standby pulse before shutting down to trigger the Bluetooth headset 102 to enter a low-power standby mode, ensuring that when the charging box 101 has no power, the Bluetooth headset 102 can still connect back to the device to be connected normally, thereby not affecting the user's normal use of the Bluetooth headset 102.

[0061] Example 2

[0062] like Figure 2 , which is a flow chart of the standby control method of the TWS Bluetooth headset of this embodiment. The standby control method of the TWS Bluetooth headset of this embodiment is implemented based on the TWS Bluetooth headset of Example 1, and includes a charging box 101 and a Bluetooth headset 102 with the same or similar structure and function as Example 1. Specifically, this embodiment includes the following steps:

[0063] S201: monitoring the insertion action of the Bluetooth headset 102 in real time to obtain a first remaining power.

[0064] The control module of the charging box 101 monitors in real time the action of placing the Bluetooth headset 102 (including the first headset and the second headset) on the charging box 101, and when the Bluetooth headset 102 is placed in the charging box 101, the control module obtains the first remaining power of the charging box 101 monitored by the first power meter 1013.

[0065] In this embodiment, the insertion action of the Bluetooth headset 102 is identified by the first charging PIN and the second charging PIN on the charging box 101 and the corresponding first connection PIN and the second connection PIN on the Bluetooth headset 102; specifically, when the first connection PIN and the first charging PIN or the second connection PIN and the second charging PIN are not connected (that is, when the Bluetooth headset 102 is placed in the charging box 101), it will cause the level of the first charging PIN and the second charging PIN to change, and the level change can be used to determine whether the Bluetooth headset 102 is placed in the charging box 101. In some other embodiments, an infrared detection structure can be provided at the corresponding position of the charging box 101, and whether the Bluetooth headset 102 is placed in the charging box 101 can be determined by detecting whether the Bluetooth headset 102 blocks the infrared detection structure.

[0066] S202: Determine whether the first remaining power meets a low power threshold.

[0067] Determine whether the first remaining power reaches a preset low power threshold. If the first remaining power reaches the low power threshold, it means that the charging box 101 is about to shut down, and its remaining power is insufficient to charge the Bluetooth headset 102. At this time, a standby instruction is generated, and then step S203 is continued; otherwise, jump to step S204.

[0068] In this embodiment, the low power threshold is determined according to the shutdown voltage of the charging box 101; Figure 3 As shown, it is a curve diagram of the relationship between the battery voltage and the battery percentage of the charging box 101 of this embodiment. It can be seen from the figure that the shutdown voltage of the charging box 101 is 3.2V, which corresponds to 0% battery power. When the battery voltage approaches 3.2V infinitely, the battery power also approaches 0%. This embodiment comprehensively considers the usage time and the stability of triggering the low-power standby mode, and sets the low-power threshold to the corresponding battery power converted from the voltage of 3.3V; of course, in some other embodiments, considering the natural aging of the battery, the low-power threshold can also be set to 3.4V or the battery power corresponding to other voltages.

[0069] S203: In response to the standby instruction, a standby pulse is generated and the Bluetooth headset 102 is controlled to enter the standby mode.

[0070] The control module of the charging box 101 generates a standby pulse of a first preset frequency according to the standby instruction. In this embodiment, the first preset frequency is 2kHz; the standby pulse is sent to the corresponding first earphone and second earphone through the first charging PIN and the second charging PIN. The first earphone and the second earphone receive the standby pulse and enter a low-power standby mode so as to be awakened before the charging box 101 is shut down due to power failure, thereby ensuring that the user can normally connect the Bluetooth headset 102 back to the device to be connected, so that the normal use of the Bluetooth headset 102 is not affected when there is no power to charge, thereby improving the user experience.

[0071] S204: Obtain the second remaining power of the Bluetooth headset 102.

[0072] When the first remaining power does not reach the low power threshold, it means that the power of the charging box 101 can still continue to charge the Bluetooth headset 102, so the control module obtains the second remaining power of the Bluetooth headset 102.

[0073] Specifically, the control module obtains the power levels of the second battery 1021 and the third battery 1023 monitored by the second power meter 1022 and the third power meter 1024 respectively. If the power levels of the second battery 1021 and the third battery 1023 are equal, the power level of the second battery 1021 or the third battery 1023 is used as the second remaining power level. If the power levels of the second battery 1021 and the third battery 1023 are not equal, the power level of the battery with smaller power between the second battery 1021 and the third battery 1023 is used as the second remaining power level.

[0074] S205: Determine whether the second remaining power is full.

[0075] Determine whether the second remaining power is full. If the second remaining power is full, it means that the second battery 1021 and the third battery 1023 of the Bluetooth headset 102 are both fully charged. At this time, there is no need to charge the Bluetooth headset 102, so a shutdown instruction is generated and then step S206 is continued; otherwise, a charging instruction is generated and the process jumps to step S208.

[0076] S206: In response to the shutdown instruction, a shutdown pulse is generated and the Bluetooth headset 102 is controlled to shut down.

[0077] The control module generates a shutdown pulse with a second preset frequency according to the shutdown instruction. In this embodiment, the second preset frequency is 1kHz; the shutdown pulse is also sent to the corresponding first earphone and second earphone through the first charging PIN and the second charging PIN. The first earphone and the second earphone receive the shutdown pulse and shut down, so as to reduce the standby power consumption of the first earphone and the second earphone, thereby reducing the battery loss of the second earphone and the third earphone, and extending the service life of the Bluetooth headset 102.

[0078] S207: Monitor the standby power of the charging box 101 in real time.

[0079] When the Bluetooth headset 102 is turned off, the charging box 101 may reach a low power threshold due to self-consumption due to long-term storage, so its power needs to be continuously monitored to trigger the low-power standby mode of the Bluetooth headset 102 in a timely manner.

[0080] The first power meter 1013 monitors the standby power of the charging box 101 in real time after the Bluetooth headset 102 is turned off, and determines whether the standby power reaches the low power threshold.

[0081] If the standby power reaches the low power threshold, the Bluetooth headset 102 is powered off and needs to be powered on first. A power-on command is generated, and the control module generates a power-on pulse of a third preset frequency based on the power-on command. In this embodiment, the third preset frequency is 1.5kHz. The power-on pulse is also sent to the first and second headsets via the first and second charging PINs, causing them to receive the power-on pulse and power on. When the Bluetooth headset 102 is powered on, a standby command is generated, and the process jumps to step S203. Otherwise, the standby power level of the charging box 101 continues to be monitored in real time.

[0082] S208: Respond to the charging instruction and charge the Bluetooth headset 102.

[0083] The control module controls the charging circuit 1014 to be turned on according to the charging instruction, and charges the first earphone and the second earphone respectively through the first charging PIN and the second charging PIN.

[0084] As a preferred embodiment of this step, when charging the first and second earphones, the charging circuit 1014 may calculate the total power required to fully charge both the first and second earphones, and combine this with a first remaining power. When the first remaining power is greater than or equal to the total power required to fully charge both the first and second earphones, the charging circuit 1014 may be controlled to charge both the first and second earphones to full power. When the first remaining power is less than the total power required to fully charge both the first and second earphones, the difference in power between the first and second earphones may be calculated, and based on the power difference and the first remaining power, the first and second earphones may be charged to a target power level of equal power. The charging circuit 1014 may then be controlled to charge both the first and second earphones to the target power level, so that the power levels of the two earphones are equal, further improving the user experience and preventing the user from being affected by the power difference between the two earphones during use.

[0085] As another preferred method of this step, when charging the two earphones separately, the charging speed of the first earphone and the second earphone can also be controlled by controlling the voltage and / or current to avoid overcharging of the earphone that reaches full charge ahead of time, resulting in battery loss, or continuing to charge the earphone that reaches the target value ahead of time, resulting in a difference in power between the two earphones and affecting the user experience.

[0086] S209: Monitor the first real-time power level and the second real-time power level, and generate a standby instruction or a shutdown instruction when conditions are met.

[0087] During the process of charging the Bluetooth headset 102 by the charging box 101, the Bluetooth headset 102 may need to be shut down when it is fully charged because the first remaining power is greater than the total power value required to fully charge the first headset and the second headset. It is also possible that the low-power standby mode of the Bluetooth headset 102 is triggered when the first remaining power is less than or equal to the total power value required to fully charge the first headset and the second headset. Therefore, it is necessary to monitor the first real-time power of the charging box 101 and the second real-time power of the Bluetooth headset 102 during the charging process to control the Bluetooth headset 102 to shut down or enter the low-power standby mode in a timely manner. Specifically:

[0088] During the charging process, the first real-time power level of the charging box 101 is monitored in real time by the first power meter 1013, and the second real-time power levels of the first earphone and the second earphone are monitored in real time by the second power meter 1022 and the third power meter 1024, respectively. In this embodiment, the second real-time power level is determined by the same rule as the second remaining power level in step S204, and this step is not further described.

[0089] Obtain the first real-time power level and determine whether the first real-time power level reaches the low power threshold. If it reaches the low power threshold, generate the standby instruction and jump to step S203. Otherwise, obtain the second real-time power level and determine whether the second real-time power level is full. If the second real-time power level is full, generate the shutdown instruction and jump to step S206. Otherwise, continue to monitor the first real-time power level of the charging box 101 and the second real-time power level of the Bluetooth headset 102.

[0090] The standby control method of the TWS Bluetooth headset in this embodiment monitors and obtains the first remaining power, the first real-time power and the standby power of the charging box 101, and generates a standby pulse when the first remaining power, the first real-time power and the standby power reach a low power threshold, so as to wake up the Bluetooth headset 102 in advance before the charging box 101 is shut down and put it into a low-power standby mode, so that the Bluetooth headset 102 can still connect normally to the device to be connected when the charging box 101 is out of power, thereby improving the user experience.

[0091] Example 3

[0092] like Figure 4 , which is a flow chart of the standby control method of the TWS Bluetooth headset of this embodiment. The standby control method of the TWS Bluetooth headset of this embodiment is implemented based on the TWS Bluetooth headset of Example 1, and includes a charging box 101 and a Bluetooth headset 102 with the same or similar structure and function as Example 1. Specifically, this embodiment includes the following steps:

[0093] S301: monitoring the insertion action of the Bluetooth headset 102 in real time to obtain a first remaining power.

[0094] The control module of the charging box 101 monitors the action of placing the Bluetooth headset 102 on the charging box 101 in real time, and when the Bluetooth headset 102 is placed in the charging box 101, the control module obtains the first remaining power of the charging box 101 monitored by the first power meter 1013.

[0095] S302: Determine whether the first remaining power meets a low power threshold.

[0096] Determine whether the first remaining power reaches a preset low power threshold. If the first remaining power reaches the low power threshold, it means that the charging box 101 is about to shut down, and its remaining power is insufficient to charge the Bluetooth headset 102. At this time, a standby instruction is generated, and then step S303 is continued; otherwise, jump to step S304.

[0097] S303: In response to the standby instruction, a standby pulse is generated and the Bluetooth headset 102 is controlled to enter the standby mode.

[0098] The control module of the charging box 101 generates a standby pulse of a first preset frequency according to the standby instruction. In this embodiment, the first preset frequency is 2kHz; the standby pulse is sent to the corresponding first earphone and second earphone through the first charging PIN and the second charging PIN. The first earphone and the second earphone receive the standby pulse and enter a low-power standby mode.

[0099] S304: Obtain the second remaining power of the Bluetooth headset 102.

[0100] When the first remaining power does not reach the low power threshold, it means that the power of the charging box 101 can still continue to charge the Bluetooth headset 102, so the control module obtains the second remaining power of the Bluetooth headset 102.

[0101] S305: Determine whether the second remaining power is full.

[0102] Determine whether the second remaining power is full. If the second remaining power is full, it means that the second battery 1021 and the third battery 1023 of the Bluetooth headset 102 are both fully charged. At this time, there is no need to charge the Bluetooth headset 102, so a shutdown instruction is generated and then step S306 is continued; otherwise, a charging instruction is generated and the process jumps to step S308.

[0103] S306: In response to the shutdown instruction, a shutdown pulse is generated and the Bluetooth headset 102 is controlled to shut down.

[0104] The control module generates a shutdown pulse with a second preset frequency according to the shutdown instruction. In this embodiment, the second preset frequency is 1kHz; the shutdown pulse is also sent to the corresponding first earphone and second earphone through the first charging PIN and the second charging PIN. The first earphone and the second earphone receive the shutdown pulse and shut down, so as to reduce the standby power consumption of the first earphone and the second earphone, thereby reducing the battery loss of the second earphone and the third earphone, and extending the service life of the Bluetooth headset 102.

[0105] S307: Monitor the standby power of the charging box 101 in real time.

[0106] When the Bluetooth headset 102 is turned off, the first power meter 1013 monitors the standby power of the charging box 101 in real time after the Bluetooth headset 102 is turned off, and determines whether the standby power reaches the low power threshold. If the standby power reaches the low power threshold, a power-on instruction is generated, and the control module generates a power-on pulse of a third preset frequency according to the power-on instruction. In this embodiment, the third preset frequency is 1.5kHz; the power-on pulse is also sent to the first headset and the second headset through the first charging PIN and the second charging PIN so that they receive the power-on pulse and turn on. When the Bluetooth headset 102 is turned on, a standby instruction is generated, and then the execution jumps to step S303. Otherwise, the standby power of the charging box 101 continues to be monitored in real time.

[0107] S308: Respond to the charging instruction and charge the Bluetooth headset 102.

[0108] The control module controls the charging circuit 1014 to be turned on according to the charging instruction, and charges the first earphone and the second earphone respectively through the first charging PIN and the second charging PIN.

[0109] S309: Monitor the first real-time power level and the second real-time power level, and generate a standby instruction or a shutdown instruction when conditions are met.

[0110] The first real-time power level of the charging box 101 during the charging process is monitored in real time by the first power meter 1013, and the second real-time power levels of the first earphone and the second earphone corresponding to the charging process are monitored in real time by the second power meter 1022 and the third power meter 1024. The first real-time power level is obtained and it is determined whether the first real-time power level has reached the low power threshold. If the low power threshold has been reached, the standby instruction is generated and the process is skipped to step S303. Otherwise, the second real-time power level is obtained and it is determined whether the second real-time power level is full. If the second real-time power level is full, the shutdown instruction is generated and the process is skipped to step S306. Otherwise, the first real-time power level of the charging box 101 and the second real-time power level of the Bluetooth earphone 102 are continuously monitored.

[0111] In this embodiment, the specific methods of steps S301 to S309 correspond to steps S201 to S209 in embodiment 2, and are not described in detail in this embodiment. In addition, this embodiment further includes the following steps:

[0112] S310: monitoring the connection request on the Bluetooth headset 102 in real time, and generating a shutdown instruction when there is no connection within a preset time period.

[0113] When the Bluetooth headset 102 enters the low-power standby mode, the connection request acting on the Bluetooth headset 102 is monitored in real time, and the duration of the low-power standby mode of the Bluetooth headset 102 is counted according to a preset timing period from the time the Bluetooth headset 102 enters the low-power standby mode. In this embodiment, the preset timing period is 6 hours; then, it is determined whether the Bluetooth headset 102 receives a connection request and connects to the device to be connected within the preset timing period. If the Bluetooth headset 102 is not connected within the preset timing period, the shutdown instruction is generated at the end of the preset timing period, and then the process jumps to step S306.

[0114] The standby control method of the TWS Bluetooth headset of this embodiment sets a preset timing period so that if there is no connection within a certain period of time after the Bluetooth headset 102 enters the low-power standby mode, the Bluetooth headset 102 will enter the shutdown mode, so as to achieve the purpose of saving energy and reducing the battery loss of the Bluetooth headset 102, thereby extending the service life of the Bluetooth headset 102 and further improving the user experience.

[0119] The judgment module 403 is used to receive the first remaining power, first real-time power and standby power monitored by the first power monitoring module 402 and respectively judge whether the first remaining power, first real-time power and standby power reach a preset low power threshold, and generate a standby instruction when the low power threshold is reached.

[0120] The pulse generating module 404 is configured to receive the standby instruction generated by the determining module 403 and generate a standby pulse of a first preset frequency according to the standby instruction. In this embodiment, the first preset frequency is 2 kHz.

[0121] The MCU module 405 is used to control the Bluetooth headset 102 to enter a low-power standby mode according to the standby pulse generated by the pulse generating module 404, so that the Bluetooth headset 102 can normally reconnect to the device to be connected when the charging box 101 has no power.

[0122] like Figure 6 As shown, as a preferred embodiment of this embodiment, it also includes a second power monitoring module 406 and a third power monitoring module 407 electrically connected to the MCU module 405, which are used to monitor the power of the first earphone and the second earphone of the Bluetooth headset 102 respectively, and determine the second remaining power and the second real-time power of the Bluetooth headset 102 based on the power of the first earphone and the second earphone, wherein the second remaining power is the current power of the Bluetooth headset 102 when the Bluetooth headset 102 is placed in, and the second real-time power is the real-time power of the Bluetooth headset 102 when the Bluetooth headset 102 is charged.

[0123] The judgment module 403 is also used to receive the second remaining power and the second real-time power monitored by the second power monitoring module 406 and / or the third power monitoring module 407 when the first remaining power does not reach the low power threshold, and to judge whether the second remaining power and the second real-time power are full, and to generate a shutdown instruction when the second remaining power and the second power are full.

[0124] The pulse generating module 404 is further configured to receive the shutdown instruction generated by the determining module 403 and generate a shutdown pulse of a second preset frequency according to the shutdown instruction. In this embodiment, the first preset frequency is 1 kHz.
