Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to better understand the technical solution of the present application, the related art related to the present application will be further described in detail below.

In the field of current electronic products, as the requirements of first equipment such as mobile phones and flat-panel earphones are thinner and thinner, and the waterproof performance of the first equipment needs to be considered, 3.5mm jack earphones or type-C earphones are gradually eliminated, and accordingly, the application of TWS earphones is more and more extensive.

Among them, the TWS headset is a true wireless stereo headset, which is a headset that plays sound using bluetooth technology, so that wireless transmission using bluetooth can be implemented instead of wired transmission.

It can be understood that the TWS headset needs to be charged, and currently, in the prior art, when charging of the TWS headset is implemented, a special charging bin is usually provided for the TWS headset, for example, as can be understood with reference to fig. 1, fig. 1 is a schematic implementation diagram of the charging bin provided in this embodiment of the present application.

As shown in fig. 1, the earphone can be placed in the charging chamber for charging, and the charging chamber itself needs to be charged, and when the charging chamber stores electric quantity, the charging of the earphone can be realized.

However, in the conventional implementation mode of specially setting the charging bin to charge the TWS headset, there are a series of problems that the TWS headset is easy to lose, the charging bin is bulky and not easy to carry, and the charging frequency of the TWS headset is limited due to less electric energy stored in the charging bin of the headset.

Aiming at the problems in the prior art, the application provides the following technical conception: the mobile phone or the tablet is the first device which can be carried by a user, and the electric quantity which can be stored by the mobile phone or the tablet is relatively large, so that if the function of the charging module of the charging bin is placed on the mobile phone or the tablet, the charging box can be omitted, the TWS earphone is charged anytime and anywhere based on the mobile phone or the tablet, the problems that the charging bin is too bulky and is not easy to carry are effectively solved, and meanwhile, the problem that the charging times of the TWS earphone are limited can be effectively solved because the electric quantity which can be stored by the mobile phone or the tablet is relatively large.

On the basis of the foregoing, the following describes in detail the earphone charging method provided in this embodiment of the present application, and it should be first explained that each embodiment of the present application may be applied to a first device, where the first device may be, for example, the above-described portable terminal device such as a mobile phone and a tablet.

In this embodiment, a battery is included in the first device for storing electrical energy for providing corresponding electrical energy to the first device and/or said headset, and at least one discharge contact is provided in the first device.

First, a method for charging an earphone provided by the present application is described with reference to fig. 2, and fig. 2 is a flowchart of the method for charging an earphone provided by the embodiment of the present application.

As shown in fig. 2, the method includes:

s201, when any one of the discharging contacts is detected to be contacted with the charging contact of the second equipment, acquiring the battery voltage of the second equipment and the battery voltage of the first equipment.

In this embodiment, at least one discharging contact is provided in the first device, wherein the discharging contact is used for performing a corresponding discharging operation when the charging contact is contacted. Thus, when the first device detects that any one of the discharging contacts is in contact with the charging contact of the second device, which may be for example a TWS headset, the battery voltage of the second device as well as the battery voltage of the first device may be obtained.

It will be appreciated that a discharge contact is provided in the first device and a charging contact is provided in the second device, when the discharge contact and the charging contact are in contact, for example, to prepare the second device for a charging operation. It will also be appreciated that including a battery in the first device and a battery in the second device, and in particular discharging the battery of the first device to charge the battery of the second device, when the first device charges the second device.

In one possible implementation, for example, a corresponding opening may be formed in the first device, the discharging contact is disposed inside the opening, and when the second device (TWS headset) is charged, for example, the headset may be inserted into the opening, so that the charging contact contacts the discharging contact. Or in an alternative implementation manner, for example, the discharging contact may be disposed on a housing of the first device, and then the first device and the second device may be kept connected by magnetic attraction or the like, so that the discharging contact is in contact with the charging contact, and charging is performed.

In an actual implementation process, a specific implementation manner of the setting position of the discharging contact in the first device and the setting position of the charging contact in the second device may be selected and set according to an actual requirement, which is not limited in this embodiment.

In this embodiment, before charging the second device, the battery voltage of the second device and the battery voltage of the first device need to be obtained, it is understood that the battery voltage of the mobile phone or the tablet is usually relatively large, but the battery voltage of the TWS headset is usually relatively small, so as to avoid the situation that the battery of the TWS headset does not over-discharge to ensure the safety of the TWS headset, the battery voltage of the second device and the battery voltage of the first device need to be obtained.

S202, acquiring the charging state of the first equipment, wherein the charging state of the first equipment comprises charging and non-charging.

After acquiring the battery voltage, for example, a current charging status of the first device may be acquired, wherein the charging status of the first device may include charging and non-charging.

And S203, if the charging state of the first device is uncharged and the battery voltage of the second device is less than the battery voltage of the first device, controlling the battery of the first device to charge the battery of the second device.

It can be understood that, when the first device is in the charging state, the battery of the second device may be damaged due to an excessively large voltage, and therefore, it is necessary to control the battery of the first device to charge the battery of the second device when the charging state of the first device is ensured to be uncharged and when the battery voltage of the second device is ensured to be less than the battery voltage of the first device, so as to effectively ensure the safety of charging the battery of the second device.

Meanwhile, when the battery of the first device is controlled to charge the battery of the second device, the battery of the first device is actually controlled to discharge the battery of the second device through the contact discharge contact and the charging contact, so as to charge the battery of the second device.

The earphone charging method provided by the embodiment of the application comprises the following steps: when any one of the discharging contacts is detected to contact the charging contact of the second device, the battery voltage of the second device and the battery voltage of the first device are acquired. And acquiring the charging state of the first equipment, wherein the charging state of the first equipment comprises charging and non-charging. And if the charging state of the first device is uncharged and the battery voltage of the second device is less than the battery voltage of the first device, controlling the battery of the first device to charge the battery of the second device. Through set up the contact that discharges in first equipment, later through the contact that discharges of the contact that charges of second equipment and first equipment, so that be uncharged at the charged state of first equipment, when the battery voltage of second equipment is less than the battery voltage of first equipment simultaneously, realize that the battery of first equipment charges to the battery of second equipment, the security of battery when the second equipment charges can effectively be guaranteed to the charging process introduced simultaneously, through realizing the charging to second equipment based on first equipment, thereby can effectively promote the use of earphone and the convenience of carrying.

In addition to the above embodiments, after controlling the battery of the first device to charge the battery of the second device, it can be understood that there is a possibility that the charging state of the first device may change, for example, if it is detected that the charging state of the first device changes from non-charging to charging, in order to protect the battery of the second device, for example, the battery of the first device may be controlled to stop charging the battery of the second device.

And displaying first prompt information on a screen of the first device, wherein the first prompt information is used for prompting that charging of the second device is stopped currently because the first device is charged.

If it is detected that the charging state of the first device is changed from charging to non-charging, for example, the battery voltage of the first device and the battery voltage of the second device may be obtained again, and when the battery voltage of the second device is smaller than the battery voltage of the first device, the battery of the first device is controlled to resume charging the battery of the second device.

After the battery of the first device is controlled to charge the battery of the second device, when the charging state change of the first device is detected to be charging, the battery of the first device is controlled to stop charging the battery of the second device, so that the safety of the battery of the second device can be effectively ensured. And when the battery of the first device is controlled to stop charging the battery of the second device, displaying a first prompt message on a screen of the first device, so that a user can quickly determine the current charging state of the second device and the reason for the change.

And on the basis of the above embodiments, it can be understood that the battery voltage of the first device and the battery voltage of the second device are continuously changed, so that after the battery of the second device is charged in the battery box controlling the first device, the battery voltage of the first device and the battery voltage of the second device can be continuously obtained.

For example, fig. 3 may be referred to for understanding, and fig. 3 is a schematic diagram illustrating an implementation of determining a charging state according to an embodiment of the present disclosure.

If it is detected that the battery voltage of the second device is greater than or equal to the battery voltage of the first device, for example, the battery of the first device may be controlled to suspend charging the battery of the second device, so as to protect the battery of the second device.

And because the battery voltage is continuously changed, after the first preset time period when the first device is suspended to be charged, the battery voltage of the second device and the battery voltage of the first device can be obtained again, and then whether the battery voltage of the second device is smaller than the battery voltage of the first device is continuously judged.

It can be understood that, in this embodiment, a longest detection time period is further set, that is, a second preset time period shown in fig. 3, so before the battery voltage of the second device and the battery voltage of the first device are obtained again, for example, it can be determined whether a time period in which the battery voltage of the second device is greater than or equal to the battery voltage of the first device exceeds the second preset time period.

If the battery voltage of the second device exceeds the battery voltage of the first device for a long time, the battery voltage of the second device at the time can be considered to exceed the battery voltage of the first device for a long time, so that the battery of the first device can be controlled to stop charging the battery of the second device, and second prompt information can be displayed on the screen of the first device, wherein the second prompt information is used for prompting the second device to stop charging because the battery voltage of the second device is greater than or equal to the battery voltage of the first device for a long time. Alternatively, if the second preset time period is not exceeded, the operation of acquiring the battery voltage of the second device and the battery voltage of the first device again may be performed.

If it is detected that the battery voltage of the second device is lower than the battery voltage of the first device, the battery of the first device may be controlled to continue to charge the battery of the second device.

Or, if it is still detected that the battery voltage of the second device is less than the battery voltage of the first device at this time, for example, the operation of obtaining the battery voltage of the second device and the battery voltage of the first device after the first preset time period may be repeatedly performed until it is determined that the battery voltage of the second device is less than the battery voltage of the first device, or until a time period in which the battery voltage of the second device is greater than or equal to the battery voltage of the first device exceeds a second preset time period.

The battery of the second device is effectively protected by controlling the first device to suspend charging to the second device when the battery voltage of the second device is detected to be greater than or equal to the battery voltage of the first device after the battery of the first device is controlled to charge to the battery of the second device. And after the first preset time length of the charging suspension, judging the relationship between the battery voltage of the second equipment and the battery voltage of the first equipment again, so that when the battery voltage of the second equipment is smaller than the battery voltage of the first equipment, the battery of the first equipment is timely recovered to charge the battery of the second equipment, and the battery safety of the second equipment is guaranteed while the effective control of the charging of the second equipment is considered. And when the battery voltage of the second device is determined to be greater than or equal to the battery voltage of the first device for more than a second preset time, the first device is controlled to stop charging the second device in time, and corresponding prompt information is displayed, so that the safety of the battery of the second device can be effectively ensured, and a user can quickly determine the change of the current charging state of the second device and the reason of the change.

On the basis of the above embodiments, the embodiment of the present application may further perform corresponding display on the power amount of the second device and corresponding control after the second device is fully charged, for example, it can be understood with reference to fig. 4, and fig. 4 is a second flowchart of the earphone charging method provided in the embodiment of the present application.

As shown in fig. 4, the method includes:

s401, acquiring the battery capacity of the second device, and displaying the battery capacity of the second device on the screen of the first device.

The first device may obtain the battery power of the second device in real time or at regular time, and display the battery power of the second device on the screen of the first device, where a specific display mode may be selected according to an actual requirement, and this embodiment is not limited thereto.

S402, if the battery capacity of the second equipment is determined to reach the preset battery capacity, controlling the battery of the first equipment to stop charging the second equipment.

After the acquired battery power, it may be further determined whether the battery power of the second device reaches a preset battery power, where the preset battery power may be 100%, that is, it may be determined whether the battery charging of the second device is completed currently, or the preset battery power may also be 95%.

When it is determined that the battery capacity of the second device reaches the preset battery capacity, it may be determined that the charging of the battery of the second device is completed, and thus the battery of the first device may be controlled to stop charging the second device.

Or if it is determined that the battery capacity of the second device does not reach the preset battery capacity, it may be determined that the battery charging of the current second device is not completed, and therefore, the battery capacity of the second device may be continuously obtained and then determined until the battery capacity of the second device reaches the preset battery capacity.

And S403, displaying third prompt information on a screen of the first device, wherein the third prompt information is used for indicating that the charging of the second device is completed.

And if the battery capacity of the second equipment reaches the preset battery capacity, controlling the battery of the first equipment to stop charging the second equipment. And displaying third prompt information on the screen of the first equipment, wherein the third prompt information is used for indicating that the charging of the second equipment is completed. By acquiring and displaying the battery power of the second device, the user can quickly and effectively determine the current charging state of the second device. And when the battery capacity of the second equipment reaches the preset battery capacity, controlling the battery of the first equipment to stop charging the second equipment so as to quickly and effectively determine the charging completion state of the second equipment, and enabling a user to quickly and effectively determine the charging completion of the second equipment by displaying the third prompt message.

In a possible implementation manner, corresponding charging indicator lamps may be further disposed on the second device or the first device, and different colors of the charging indicator lamps corresponding to the various kinds of prompt information are set to indicate the current charging state of the second device.

Based on the above-described embodiments, a specific control process for charging the first device and the second device is described below with reference to fig. 5, where fig. 5 is a schematic diagram of a charging module provided in an embodiment of the present application.

The following description will be made by taking the first device as a mobile phone and the second device as a TWS headset, with reference to fig. 5:

1. the TWS headset is plugged in, if the battery of the TWS headset is not discharged too much, VBAT _ TWS is voltage and may generate an interrupt to a Power Management Unit (PMU), i.e. INT in fig. 5, which indicates an interrupt signal, which may be triggered when a high level is input.

2. The power management unit, after receiving INT interrupt, will make BOOST _ EN output a high level to the BOOST chip (BOOST), which will BOOST the voltage VBAT of the handset battery to 5V (i.e. VCHG _ TWS _ 5V).

The BOOST chip may be a BOOST chip, which is a direct current-to-direct current (DC-DC) BOOST chip. The BOOST _ EN represents a control signal, generally outputs a high level of 1.8V, and may be used as an enable (enable) signal of the BOOST chip. VBAT is the battery voltage of products such as mobile phones or tablets, and the voltage range generally is: 3.4V-4.35V. VCHG _ TWS _5V is the TWS headset charging input voltage, typically 5V.

3. Because the enable signal of the CHARGE management chip (CHARGE IC) is active low, the CHARGE chip receives a 5V (i.e., VCHG _ TWS _5V) signal, and then automatically starts the charging function, and the output of the CHARGE chip is directly connected to VBAT _ TWS.

VBAT _ TWS is the battery voltage inside the TWS headset, and the operating range is generally: 2.4V-4.35V;

4. the charge management chip may also have a charge indicator function (charge _ LED) and a charge current setting (through Rset) function, for example.

And also the meaning of the various parameters in fig. 5, where VIN is the input signal; VOUT is an output signal; SW is a switch signal, and a boosting function can be realized by matching with an inductor; wherein CHG _ EN is a charge enable signal, active low; wherein the LED _ CTRL is used for controlling the charging indicator lamp; the Charge _ LED is a charging indicator light, and is connected in series with a resistor R1 for current limiting to prevent the LED light from being burned out, and the resistance of the resistor R1 may be 1k ohm, for example; and wherein I _ charging is the charging current of the TWS headset can be adjusted by adjusting the magnitude of the resistance value of the Rset resistor. And the resistance of the resistor R2 in fig. 5 may be, for example, 10k ohms.

And in an alternative implementation, if the battery of the TWS headset is too discharged, for example, VBAT _ TWS voltage is 0V, and cannot trigger an interrupt, then a function can be performed on the UI interface of the handset, such as: setting- > TWS earphone management- > battery overdischarging and battery activation; for example, when the user clicks the option, the PMU will actively pull up BOOST _ EN, and the charging function will be forced to be turned on, that is, when the charging condition is not satisfied, if the user still needs to perform charging, forced charging may be performed.

Based on the above description, it can be determined that the charging module of the TWS headset and the charging of the mobile phone are completely independent, and the conflict of application scenarios is avoided.

And further details of implementation of the discharging contact in the first device are described below with reference to fig. 6 to 17, where fig. 6 is a schematic front view of the first device provided in this embodiment of the present application for charging the second device, fig. 7 is a schematic back view of the first device provided in this embodiment of the present application for charging the second device, fig. 8 is a schematic front view of the first device provided in this embodiment of the present application for not providing charging, fig. 9 is a schematic back view of the first device provided in this embodiment of the present application for not providing charging, fig. 10 is a schematic side view of the opening of the first device provided in this embodiment of the present application, fig. 11 is a schematic left side view of the first device provided in this embodiment of the present application, fig. 12 is a schematic right side view of the first device provided in this embodiment of the present application, and fig. 13 is a schematic bottom view of the first device provided in this embodiment of the present application, fig. 14 is a schematic view illustrating the rubber stopper not being inserted into the opening, fig. 15 is a schematic view illustrating the rubber stopper being inserted into the opening, fig. 16 is a schematic view illustrating the spring plate not being sprung open, and fig. 17 is a schematic view illustrating the spring plate being sprung open.

In one possible embodiment, at least one opening is provided, for example at the edge of the first device, in which opening the discharge contact is provided.

The discharge contact of the first device and the charging contact of the second device may be connected by magnetic attraction, for example.

As can be appreciated with reference to fig. 6, for example, as shown in fig. 6, a left opening and an opening as shown in fig. 6 may be provided in the first device, wherein a discharge contact is provided in the opening. And referring to fig. 6, wherein a TWS left earpiece may be inserted into the left side aperture for charging of the left earpiece, and a TWS right earpiece may be inserted into the right side aperture for charging of the right earpiece.

And in one possible implementation, for example, a TWS headset may be placed in an upper opening of the first device (typically about 6mm in diameter for a headset, comparable to the thickness of a cell phone) to initiate an automatic charging mode; for example, the charging contact can be just corresponding to the contact on the mainboard to the earphone side, and the magnetic type connection is adopted, so that the charging contact can be ensured not to drop easily.

The front view of the first device when the second device is charging in the first device is described above in connection with fig. 6, and it can also be understood from fig. 7 that the charging is a back view of the first device, with reference to fig. 7, where the TWS left earpiece, the TWS right earpiece, the left side aperture, and the right side aperture are similar to those described above.

And, since the opening for charging the headphone is provided inside the first device, the first device seems to be absent when the first device is not charging, and for example, a front view and a back view when the first device is not charging the headphone can be understood in conjunction with fig. 8 and 9.

Referring to fig. 8, when the first device is not charging the headset, its front side appears to be a normal device including a front camera and an earpiece opening. And referring to fig. 9, when the first device does not perform charging of the headset, its back side appears to be a general device including a rear camera and a flash.

And, for better understanding of the opening of the first device, for example, a side view of the opening of the first device may also be understood in connection with fig. 10, as shown in fig. 10, where a left side opening and a right side bayonet of the side of the first device are shown, and for ease of understanding the side view, the position of the noise reduction microphone is also shown in fig. 10.

And, since the opening for charging the headphone is provided inside the first device, the first device seems to be absent when the first device is not charging, for example, a side view when the first device is not charging the headphone can be understood in conjunction with fig. 11 to 13.

Referring to fig. 11, when the first device does not perform charging of the headset, the left side thereof appears to be a general device including a Subscriber Identity Module (SIM) card slot and a flash memory (TF) card slot. And referring to fig. 12, when the first device does not perform charging of the headset, the right side thereof appears as a general device including a volume up key and a volume down key, and a power-on key. And referring to fig. 13, when the first device is not charging the headset, its underside appears to be a normal device including a main microphone and Universal Serial Bus (USB) interface and a speaker opening.

It will also be appreciated that the above described aperture is provided in the first device for charging the second device, but that the dust and splash protection of the aperture in the first device may also be considered when the second device is not being charged.

In one possible implementation, for example, a removable rubber plug is provided in the opening; alternatively, a movable spring plate is disposed in the opening.

The following describes possible implementations of the rubber stopper and the spring plate with reference to the drawings.

First, an implementation of the rubber plug is described with reference to fig. 14 and 15, as shown in fig. 14, when the first device charges the earphone, the rubber plug may not be inserted into the opening, so that the earphone may be inserted into the opening for charging. And as shown in fig. 15, when the first device does not charge the earphone, for example, the rubber stopper can be inserted into the opening hole to realize the dust and splash prevention of the first device.

Next, an implementation of the spring plate is described with reference to fig. 16 and 17, where the spring plate can be automatically opened and closed, as shown in fig. 16, when the first device does not charge the earphone, the spring plate can block the opening, so as to achieve dust prevention and water splash prevention, where the spring plate may be, for example, a circular spring plate with a size consistent with that of the opening. As shown in fig. 17, when the first device charges the earphone, the spring plate can be pressed downward by an external force during the process of inserting the earphone into the first device, so that the earphone can be charged through the opening. After the charging of the earphone is completed, when the earphone is pulled out, the spring piece can be restored to the original position by the elasticity of the spring.

To sum up, according to the earphone charging method provided by the embodiment of the application, the charging management module and the hole for the TWS earphone are arranged on the portable device such as a mobile phone or a tablet, and the TWS earphone is powered by the boosted battery voltage of the mobile phone, so that the TWS earphone can be charged based on the portable device, an additional charging bin is omitted, the problems of being too bulky in the charging bin and not easy to carry are solved, and the problem that the charging times of the TWS earphone are limited due to the fact that the mobile phone or the tablet can store more electric quantity is solved.
