Description

Technical Field

[0001] This application belongs to the field of headphone technology, and in particular relates to a wireless headphone charging method, system and terminal device. Background Technology

[0002] After the earbuds are placed in the charging case and the charging circuit is connected to an external power source, the controller simultaneously charges both the earbuds and the charging case. In some cases, insufficient driving capability of the charging circuit may cause the output voltage to drop below the preset voltage value, resulting in slower charging speeds for both the earbuds and the charging case.

[0003] For example, in some cases, the undervoltage protection threshold for the earphones is W1, and the undervoltage protection threshold for the charging case is W2. If the output voltage of the charging circuit is less than W2, the charging case will stop charging. Once the charging case stops charging, the output voltage of the charging circuit may rise above W2, and the charging case will start charging again. When the charging case starts charging, the output voltage of the charging circuit may drop below W2 again, and this cycle repeats, causing the charging of the charging case to be in a state of constant fluctuation, resulting in a long charging time. Similarly, the earphones also face the same problem; they may be in a state of fluctuation during charging, leading to a long charging time. Summary of the Invention

[0004] This application provides a wireless earphone charging method, system, and terminal device, which can solve the problem of slow charging speed caused by a decrease in the output voltage of the charging circuit.

[0014] When the charging current of the earphone case is adjusted to the charging current of the third earphone case, and the output voltage is greater than or equal to the first preset voltage, the controller stops adjusting the charging current of the earphone case.

[0015] When the charging current of the earphone case is adjusted to the third earphone case charging current, and the output voltage is still less than the first preset voltage, the controller controls the earphone case to stop charging.

[0016] In one possible implementation of the first aspect, after the controller controls the earphone case to stop charging, the wireless earphone charging method further includes:

[0017] When the controller stops the charging of the earphone case, and the output voltage is still less than the first preset voltage, the controller adjusts the charging current of the earphone from the first earphone charging current to the second earphone charging current; wherein, the first earphone charging current is the rated charging current of the earphone, and the first earphone charging current is greater than the second earphone charging current;

[0018] When the charging current of the earphone is adjusted to the charging current of the second earphone, and the output voltage is greater than or equal to the first preset voltage, the controller stops adjusting the charging current of the earphone.

[0019] In one possible implementation of the first aspect, after the controller adjusts the charging current of the earphone from a first earphone charging current to a second earphone charging current, the wireless earphone charging method further includes:

[0020] When the charging current of the earphone is adjusted to the charging current of the second earphone, and the output voltage is still less than the first preset voltage, the controller controls the earphone to stop charging.

[0021] In one possible implementation of the first aspect, the wireless earphone charging system further includes an alarm device electrically connected to the controller;

[0034] The beneficial effects of the embodiments in this application compared with the prior art are:

[0035] When charging both the earbuds and the charging case simultaneously, the controller receives the output voltage from the charging circuit. If the output voltage is lower than a first preset voltage, the controller adjusts the charging current of the charging case to decrease until the output voltage is greater than or equal to the first preset voltage. At this point, the controller stops adjusting the charging current of the charging case. This ensures that the output voltage of the charging circuit meets the charging requirements of the earbuds, ensuring normal charging and maintaining a fast charging speed.

[0036] It is understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details.

[0050] Figure 1 A structural block diagram of a wireless earphone charging system provided in an embodiment of this application is shown. See also... Figure 1 As shown, the wireless earphone charging system includes a charging circuit 10, a controller 20, earphones 30, and an earphone case 40. The input terminal of the charging circuit 10 is electrically connected to an external power source, and the output terminal of the charging circuit 10 is electrically connected to the input terminal of the controller 20. The output terminals of the controller 20 are electrically connected to both the earphones 30 and the earphone case 40. The charging circuit 10 converts electrical energy provided by the external power source and charges the earphones 30 and the earphone case 40 through the controller 20. The controller 20 regulates the charging current of the earphones 30 and the earphone case 40.

[0051] When the earphone 30 and the earphone case 40 are charged simultaneously, the controller 20 collects the output voltage of the charging circuit 10 in real time (that is, the charging voltage of the earphone 30 and the earphone case 40). When the output voltage of the charging circuit 10 is less than the first preset voltage, the controller 20 adjusts the charging current of the earphone case 40 to reduce the load of the charging circuit 10, thereby increasing the output voltage of the charging circuit 10, preventing the undervoltage protection of the earphone 30 from being triggered, ensuring that the earphone 30 is charged normally, and guaranteeing the charging speed of the earphone 30.

[0052] Once the earphone 30 has finished charging, the controller 20 stops charging the earphone 30, reduces the load on the charging circuit 10, increases the output voltage of the charging circuit 10, ensures the normal charging of the earphone case 40, and guarantees the charging speed of the earphone case 40.

[0053] The wireless earphone charging system provided in this embodiment prioritizes charging the earphone 30. When the output voltage of the charging circuit 10 is normal, the controller 20 controls the earphone 30 and the earphone case 40 to charge normally. When the output voltage of the charging circuit 10 drops below a first preset voltage, the controller 20 reduces the charging current of the earphone case 40, reducing the load on the charging circuit 10 to increase the output voltage of the charging circuit 10 and ensure that the earphone 30 can be powered normally. When the earphone 30 is fully charged, the controller 20 controls the earphone 30 to stop charging, ensuring that the earphone case 40 is powered normally. This avoids the phenomenon of undervoltage protection in the earphone 30 or the earphone case 40 due to the output voltage of the charging circuit 10 being lower than the first preset voltage, thereby improving the charging speed of the earphone 30 and the earphone case 40.

[0054] It should be noted that the first preset voltage can be set according to actual conditions. For example, if the first preset voltage is set to 4.5V, when the output voltage of the charging circuit 10 is less than 4.5V, it will cause the earphone 30 to trigger undervoltage protection, resulting in a cycle of charging and stopping the earphone 30, affecting the normal charging of the earphone 30. At this time, the controller 20 reduces the charging current of the earphone case 40 and reduces the load of the charging circuit 10 to increase the output voltage of the charging circuit 10, making the output voltage of the charging circuit 10 greater than 4.5V. This ensures that the earphone 30 will not trigger undervoltage protection, guarantees that the earphone 30 can be powered normally, and improves the charging efficiency of the earphone 30.

[0055] Figure 2 A schematic flowchart of a wireless earphone charging method provided in an embodiment of this application is shown. This wireless earphone charging method is applied to a wireless earphone charging system, which includes a charging circuit, a controller, earphones, and an earphone case. The input terminal of the charging circuit is electrically connected to an external power source, and the output terminal of the charging circuit is electrically connected to the input terminal of the controller. The output terminal of the controller is electrically connected to both the earphones and the earphone case. The charging circuit converts electrical energy supplied by the external power source and charges the earphones and earphone case through the controller. The controller regulates the charging current of the earphones and earphone case. See also... Figure 2 As shown, when charging the earphones and the earphone case simultaneously, the wireless earphone charging method includes steps S201 and S202.

[0056] Step S201: The controller acquires the output voltage of the charging circuit.

[0057] Specifically, during the charging process of the earphones and earphone case, the controller collects the output voltage of the charging circuit in real time.

[0058] In step S202, when the output voltage is less than the first preset voltage, the controller adjusts the charging current of the earphone case to decrease until the output voltage is greater than or equal to the first preset voltage, at which point the controller stops adjusting the charging current of the earphone case.

[0059] Specifically, the first preset voltage is a pre-set voltage value, which designers can set according to actual conditions. When the output voltage of the charging circuit is lower than the first preset voltage, the undervoltage protection of the earphones is triggered, causing the earphones to cycle between charging and stopping, reducing the charging speed. At this time, the controller adjusts the charging current of the earphone case to decrease, reducing the load on the charging circuit and increasing the output voltage of the charging circuit. When the output voltage of the charging circuit increases to be greater than or equal to the first preset voltage, the controller stops adjusting the charging current of the earphone case. At this time, the output voltage of the charging circuit meets the normal charging requirements of the earphones, ensuring that the earphones can always be in a charging state and can charge at the rated current, improving the charging speed. When the earphones are fully charged, the controller controls the earphones to stop charging and controls the charging current of the earphone case to increase, ensuring the normal charging of the earphone case.

[0060] The wireless earphone charging method provided in this application embodiment can ensure that the earphones and earphone case do not trigger undervoltage protection during the charging process, so that the earphones and earphone case are always in a charging state, thereby improving the charging speed of the earphones and earphone case.

[0061] Figure 3 A schematic flowchart illustrating a wireless earphone charging method according to another embodiment of this application is shown. See also Figure 3 As shown, step S202 includes steps S2021 and S2022.

[0062] Step S2021: When the output voltage is less than the first preset voltage, the controller adjusts the charging current of the earphone case from the first earphone case charging current to the second earphone case charging current.

[0063] Specifically, the first earphone charging current is the rated charging current of the earphone case, and it is greater than the second earphone charging current. When the controller controls the earphones and earphone case to charge simultaneously, and the output voltage of the charging circuit is greater than or equal to a first preset voltage, the controller controls the charging current of the earphone case to be the first earphone charging current, and the charging current of the earphones to be the first earphone charging current. When the output voltage of the charging circuit decreases to below the first preset voltage, the earphones will experience undervoltage protection. At this time, the controller adjusts the charging current of the earphone case from the first earphone charging current to the second earphone charging current, thereby reducing the charging current of the earphone case, reducing the load on the charging circuit, and increasing the output voltage of the charging circuit.

[0064] It should be noted that designers can set the specific value of the charging current of the second earphone case according to the actual situation. For example, the charging current of the second earphone case can be set to 80% of the rated charging current of the earphone case. When the output voltage is less than the first preset voltage, the controller will adjust the charging current of the earphone case to 80% of the rated charging current, thereby reducing the charging current of the earphone case.

[0065] In step S2022, when the charging current of the earphone case is adjusted to the second earphone case charging current and the output voltage is greater than or equal to the first preset voltage, the controller stops adjusting the charging current of the earphone case.

[0066] Specifically, when the charging current of the earphone case is adjusted to the second earphone case charging current, and the output voltage is greater than or equal to the first preset voltage, the output voltage of the charging circuit meets the requirements for normal earphone charging. The controller stops adjusting the charging current of the earphone case, so that the earphone case maintains the current charging current, thereby ensuring the stability of the output voltage of the charging circuit, thus ensuring normal earphone charging and improving the charging speed of the earphone.

[0067] like Figure 3 As shown, step S2021 is followed by steps S2023 to S2025.

[0068] Step S2023: When the charging current of the earphone case is adjusted to the second earphone case charging current, and the output voltage is still less than the first preset voltage, the controller adjusts the charging current of the earphone case from the second earphone case charging current to the third earphone case charging current.

[0069] Specifically, the charging current of the third earphone case is less than that of the second earphone case. When the charging current of the earphone case is adjusted to the level of the second earphone case, if the output voltage is still less than the first preset voltage, the earphones will still experience undervoltage protection. The controller adjusts the charging current of the earphone case from the second earphone case to the third earphone case, further reducing the charging current of the earphone case and thus further increasing the output voltage of the charging circuit.

[0070] It should be noted that designers can set the specific value of the third earphone charging current according to the actual situation. For example, the charging current of the third earphone can be set to 50% of the rated charging current of the earphone. When the charging current of the earphone is adjusted to the charging current of the second earphone, and the output voltage is still less than the first preset voltage, the controller will adjust the charging current of the earphone to 50% of the rated charging current, thereby further reducing the charging current of the earphone.

[0071] In step S2024, when the charging current of the earphone case is adjusted to the third earphone case charging current and the output voltage is greater than or equal to the first preset voltage, the controller stops adjusting the charging current of the earphone case.

[0072] Specifically, when the charging current of the earphone case is adjusted to the third earphone case charging current, and the output voltage is greater than or equal to the first preset voltage, the output voltage of the charging circuit meets the requirements for normal earphone charging. At this time, the controller stops adjusting the charging current of the earphone case, so that the earphone case maintains the current charging current, thereby ensuring the stability of the output voltage of the charging circuit, thus ensuring normal earphone charging and improving the charging speed of the earphone.

[0073] In step S2025, when the charging current of the earphone case is adjusted to the third earphone case charging current and the output voltage is still less than the first preset voltage, the controller controls the earphone case to stop charging.

[0074] Specifically, when the charging current of the earphone case is adjusted to the third earphone case charging current, if the output voltage is still lower than the first preset voltage, the earphones will still experience undervoltage protection. The controller then stops the earphone case from charging, further reducing the load on the charging circuit and thereby further increasing the output voltage of the charging current so that the output voltage of the charging circuit meets the requirements for normal earphone charging.

[0075] like Figure 3 As shown, step S2025 is followed by steps S2026 and S2027.

[0076] Step S2026: When the controller stops the headphone box from charging, and the output voltage is still less than the first preset voltage, the controller adjusts the headphone charging current from the first headphone charging current to the second headphone charging current.

[0077] Specifically, the first earphone charging current is the earphone's rated charging current, and this first earphone charging current is greater than the second earphone charging current. When the controller stops charging the earphone case, if the output voltage is still lower than the first preset voltage, the earphones will still experience undervoltage protection. The controller will then adjust the earphone charging current from the first earphone charging current to the second earphone charging current, reducing the earphone charging current and thus increasing the output voltage of the charging circuit.

[0078] It should be noted that designers can set the specific value of the second earphone charging current according to the actual situation, for example, setting the second earphone charging current to 70% of the earphone's rated charging current. When the controller stops the earphone case from charging, if the output voltage is still lower than the first preset voltage, the controller will adjust the earphone charging current to 70% of the rated charging current, reducing the load on the charging circuit so that the output voltage of the charging circuit increases.

[0079] In step S2027, when the charging current of the headphones is adjusted to the second headphone charging current and the output voltage is greater than or equal to the first preset voltage, the controller stops adjusting the charging current of the headphones.

[0080] Specifically, when the charging current of the headphones is adjusted to the second headphone charging current, and the output voltage is greater than or equal to the first preset voltage, the output voltage of the charging circuit meets the requirements for normal headphone charging. At this time, the controller stops adjusting the charging current of the headphones, so that the headphones maintain the current charging current and ensure normal charging of the headphones.

[0081] like Figure 3 As shown, step S2026 is followed by steps S2028 and S2029.

[0082] In step S2028, when the charging current of the headphones is adjusted to the second headphone charging current and the output voltage is still less than the first preset voltage, the controller controls the headphones to stop charging.

[0083] Specifically, when the charging current of the headphones is adjusted to the second headphone charging current, if the output voltage is still less than the first preset voltage, the headphones will still experience undervoltage protection and cannot supply power normally. At this time, the controller will control the headphones to stop charging.

[0084] Step S2029: When the charging current of the headphones is adjusted to the second headphone charging current, and the output voltage is still less than the first preset voltage, the controller controls the alarm device to send an alarm message.

[0085] Specifically, when the output voltage of the charging circuit decreases, causing the controller to stop charging the headphones and headphone case, the controller will control the alarm device to send an alarm message to alert the user so that the user can handle the fault in a timely manner after receiving the alarm message (such as replacing the charging power supply or the charger).

[0086] For example, the alarm device can be a buzzer, which is electrically connected to the controller. When the output voltage of the charging circuit decreases, causing the controller to stop charging the headphones and headphone case, the controller controls the buzzer to sound, alerting the user that the headphones have a charging fault, thus providing a fault alarm.

[0087] The alarm device can also use indicator lights, which are electrically connected to the controller. When the output voltage of the charging circuit decreases, causing the controller to stop charging the headphones and headphone case, the controller will control the indicator lights to flash at a set frequency to alert the user that the headphones have a charging fault, thus providing a fault alarm.

[0088] Figure 4 A schematic flowchart illustrating a wireless earphone charging method according to another embodiment of this application is shown. See also Figure 4 As shown, the wireless earphone charging method also includes steps S401 and S402.

[0089] Step S401: The controller obtains the actual battery level of the headphones.

[0090] In step S402, if the actual battery level of the earphone is greater than the first preset battery level, the controller reduces the charging current of the earphone.

[0091] Specifically, the controller obtains the actual battery level of the earphones in real time. When the actual battery level of the earphones is greater than a first preset value, the controller reduces the charging current of the earphones, reduces the load on the charging circuit, ensures that the output voltage of the charging circuit can meet the charging requirements of the earphone case, ensures that the earphone case can be charged normally all the time, and improves the charging speed of the earphone case.

[0092] For example, if the earphones have a capacity of 1000mA, when the actual battery level of the earphones is less than 800mA (80% of the capacity), the controller uses a larger charging current to charge the earphones, achieving fast charging. When the actual battery level of the earphones is greater than 800mA, the controller uses a smaller current to charge the earphones. In this case, the load on the rechargeable circuit is reduced, ensuring that the output voltage of the charging circuit can meet the charging requirements of the earphone case, guaranteeing that the earphone case can continue to charge normally and improving the charging speed of the earphone case.

[0093] Figure 5 A schematic flowchart illustrating a wireless earphone charging method according to another embodiment of this application is shown. See also Figure 5 As shown, the wireless earphone charging method further includes steps S501 and S502.

[0094] Step S501: The controller obtains the actual battery level of the earphone case.

[0095] In step S502, if the actual battery level of the earphone case is greater than the second preset battery level, the controller reduces the charging current of the earphone case.

[0096] Specifically, the controller obtains the actual battery level of the earphone case in real time. When the actual battery level of the earphone case is greater than a second preset value, the controller reduces the charging current of the earphone case, reduces the load on the charging circuit, ensures that the output voltage of the charging circuit can meet the charging needs of the earphone, ensures that the earphone can be charged normally all the time, and improves the charging speed of the earphone.

[0097] For example, the earphone case has a capacity of 2000mA. When the actual battery level of the earphone case is less than 1600mA (80% of its capacity), the controller uses a larger charging current to charge the earphone case, achieving fast charging. When the actual battery level of the earphone case is greater than 1600mA, the controller uses a smaller current to charge the earphone case. In this case, the load on the rechargeable circuit is reduced, ensuring that the output voltage of the charging circuit can meet the charging needs of the earphones, guaranteeing that the earphones can continue to charge normally, and improving the charging speed of the earphones.
