The TWS earphone is a true wireless stereo earphone which plays sound by utilizing the Bluetooth technology, so that wireless transmission by utilizing Bluetooth can be realized to replace wired transmission.
It can be understood that the TWS earphone needs to be charged, and in the prior art, when the TWS earphone is charged, a special charging bin is usually provided for the TWS earphone, for example, as can be understood with reference to fig. 1, fig. 1 is a schematic implementation diagram of the charging bin provided in the embodiment of the present application.
As shown in fig. 1, the earphone can be placed in the charging bin for charging, and the charging bin itself needs to be charged, so that the earphone can be charged when the charging bin stores electric quantity.
However, at present, in the implementation mode of specially setting the charging bin to realize charging the TWS earphone, the TWS earphone is easy to lose, the charging bin is bulky and is not easy to carry, and because the electric energy stored in the earphone charging bin is less, a series of problems such as limited charging times of the TWS earphone are caused.
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 more, 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, and the TWS earphone is charged anytime and anywhere based on the mobile phone or the tablet, so that the problem that the charging bin is bulky and is not easy to carry is effectively solved, and meanwhile, the problem that the number of times of charging of the TWS earphone is limited can be effectively solved because the electric quantity which can be stored by the mobile phone or the tablet is more.
On the basis of the foregoing, the following describes in detail the earphone charging method provided in the embodiment of the present application, and first, it should be noted that each embodiment in the present application may be applied to a first device, where the first device may be, for example, a mobile phone, a tablet, or a portable terminal device, where the specific implementation manner of the first device is not limited, and any portable terminal device may be used as the first device in the embodiment, for example, the first device may also be a smart watch, or the like.

On the basis of the above-described embodiments, a specific control procedure of charging the first device and the second device will be described below with reference to fig. 5, and fig. 5 is a schematic diagram of a charging module provided in an embodiment of the present application.
The following description will take the example that the first device is a mobile phone, and the second device is a TWS headset, referring to fig. 5:
1. the TWS headset is plugged in, if the battery of the TWS headset is not overdriven, VBAT_TWS is voltage and an interrupt may be generated to the power management unit (power management unit, PMU), i.e. INT in FIG. 5, indicating an interrupt signal, which may be triggered at a high level input.
2. After receiving the INT interrupt, the power management unit outputs a high level to the BOOST chip (BOOST) that BOOSTs the voltage VBAT of the mobile phone 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. Boost_en represents a control signal, typically outputting a 1.8V high level, which can be used as an enable (enable) signal for the BOOST chip. VBAT is the battery voltage of the mobile phone or tablet product itself, and the voltage range is generally: 3.4V-4.35V. Vchg_tws_5v is the TWS headset charge input voltage, typically 5V.
3. Since the enable signal of the CHARGE management chip (CHARGE IC) is active low, the CHARGE chip receives a 5V (i.e., vchg_tws_5v) and then automatically turns on the CHARGE function, the output of which is directly connected to vbat_tws.
Wherein vbat_tws is the battery voltage inside the TWS earphone, and the working range is generally: 2.4V-4.35V;
4. the charge management chip may also have, for example, a charge indicator lamp function (charge_led) and a charge current setting (by Rset) function.
And the meaning of the parameters in fig. 5, wherein VIN is the input signal, needs to be described; VOUT is the output signal; SW is a switch signal, and the boost function can be realized by matching with the inductor; wherein chg_en is a charge on signal, active low; wherein led_ctrl is charge indicator control; the charge_LED is a charging indicator lamp, and a resistor R1 is connected in series for limiting current to prevent the LED lamp from being burnt out, wherein the resistance value of the resistor R1 can be 1k ohm; and wherein i_charging is to adjust the charging current of the TWS earphone by adjusting the magnitude of the resistance value of the Rset resistor. And the resistance of resistor R2 in fig. 5 may be, for example, 10k ohms.
And in an alternative implementation, if the battery of the TWS earphone is overdischarged, for example, the vbat_tws voltage is 0V, and the interrupt cannot be triggered, a function may be performed on the UI interface of the mobile phone, for example: setting- > TWS earphone management- > over-discharge of battery and activation of the battery; for example, when the user clicks the option, the PMU actively pulls up boost_en, and the charging function is forced to be turned on, that is, when the charging condition is not satisfied, if the user still needs to charge, forced charging can 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, so that the conflict of application scenes is avoided.
