The NFC antenna group 11 is configured to receive electric energy transmitted by an NFC antenna set in the terminal during a charging process;

a power management chip 12 electrically connected with the NFC antenna group 11, for wirelessly charging the first power component 14 and/or a second power component of a wireless earphone with the electric energy, wherein the wireless earphone is detachably accommodated in the earphone box 10;

The NFC antenna group 11 may include an NFC coil capable of generating magnetic field induction, and is disposed on the surface of the earphone box 10, so that when a terminal having an NFC antenna is close to the surface of the earphone box 10, the coil inside the NFC antenna group 11 generates an induction current, that is, enables transmission of electric power from the terminal to the earphone box 10.

The Power management chip 12 is mainly responsible for rectifying or externally rectifying voltage and current and managing the battery in a charging state, and may be a PMIC (Power MANAGEMENT IC, power management integrated circuit), which is connected with the NFC antenna group 11 through I2C, and directly transmits the electric energy received by the NFC antenna group 11 to the Power management chip 12, where the Power management chip 12 rectifies the electric energy and converts the electric energy into a suitable charging voltage, so that the electric energy output end of the Power management chip 12 charges the battery of the first Power component 14, that is, the earphone box, or charges the second Power component of the wireless earphone.

The NFC controller 25 is mainly responsible for communicating with the NFC antenna of the terminal through the NFC antenna group 21, and performs a negotiation operation of wireless charging. The NFC controller 25 and the power management chip 22 operate in parallel without communication with each other, and both communicate unidirectionally with the microcontroller 23 through the I2C.

Typically, an NFC antenna on the terminal emits a radio frequency signal, and when the terminal approaches the earphone box, the NFC antenna in the earphone box generates an induced current, so that the NFC controller detects the presence of an NFC radio frequency field.

If the NFC controller 25 detects that the NFC radio frequency field exists, the microcontroller 23 is notified to start the charging process, and then the microcontroller 23 controls the power management chip 22 to wirelessly charge the first power component 24 or the second power component of the wireless headset.

If the NFC controller 25 does not detect the presence of the NFC radio frequency field, it periodically continues to detect whether the NFC radio frequency field is present around the earphone box 20 until the terminal is away from the earphone box 20 (whether the terminal is away from the earphone box 20 can be detected by the sensor).

According to the embodiment of the application, the NFC controller in the earphone box is in wireless communication with the terminal close to the earphone box, and whether the NFC radio frequency field exists around the earphone box is detected, so that a safe charging process between the terminal and the earphone box is ensured, and the charging efficiency is improved.

As shown in fig. 3B, the sensor 313 is disposed on the front side (current visual direction) of the earphone box 30, and the sensor 314 is disposed on the back side (opposite direction of current visual direction) of the earphone box 30, and may be a hall sensor, wherein the sensor 313 is configured to send a second notification message to the microcontroller 33 when detecting the electromagnetic induction current generated by the NFC coil 311, indicating that the front side of the earphone box 30 detects the NFC antenna proximity of the terminal, and the sensor 314 is configured to send a second notification message to the microcontroller 33 when detecting the electromagnetic induction current generated by the NFC coil 312, indicating that the back side of the earphone box 30 detects the NFC antenna proximity of the terminal. Therefore, the terminal can detect the radio frequency field when approaching to any surface of the earphone box, and the charging process is started.

The microcontroller 33 receives the second notification message sent by the sensor 313, controls the NFC controller 35 to be connected with the NFC coil 311 of the first antenna group or the NFC coil 312 of the second antenna group through the first switch 315, and controls the power management chip 32 to be connected with the NFC coil 311 of the first antenna group or the NFC coil 312 of the second antenna group through the first switch 315, so as to realize the function that both the front and back sides of the earphone box can be wirelessly charged.

The first switch 315 and the second switch 321 may be MOS switches or triode switches, etc.

In some embodiments, a first power output port of the power management chip 32 is connected to the first power component 34 through the second switch 321 and is used for wirelessly charging the first power component 34 by using the power received by the NFC antenna group, and a second power output port of the power management chip 32 is connected to the second power component 36 of the wireless headset through the second switch 321 and is used for wirelessly charging the second power component 36 by using the power received by the NFC antenna group. The power management chip 32 is connected to the first power supply assembly 34 and the second power supply assembly 36 through two power output ports, respectively, to ensure that appropriate voltages are output to the respective power supply assemblies.

The first and second power supply assemblies 34 and 36 may include only a storage battery, or the first and second power supply assemblies 34 and 36 may include a storage battery and a charging IC.

The microcontroller 33 is further configured to detect whether the wireless headset is received in the headset box 30 in response to the first notification message before the microcontroller 33 controls the power management chip 32 to charge the first power supply component 34 and/or the second power supply component 36.

When the wireless earphone is accommodated in the accommodating body of the earphone box, the positive electrode contact of the wireless earphone is in butt joint with the positive electrode contact of the earphone box, and the negative electrode contact of the wireless earphone is in butt joint with the negative electrode contact of the earphone box, so that the earphone box can wirelessly charge the wireless earphone, and the positive electrode contact of the wireless earphone is communicated with the wireless earphone. For example, forced bluetooth pairing, wireless headset power inquiry, switch box action notification, over-the-air upgrade triggering and the like can be realized between the headset box and the wireless headset.

In the case that the wireless earphone is accommodated in the earphone box 30, the microcontroller 33 is further configured to control the second switch 321 to be turned on with the first power supply assembly 34 in the case that it is determined that the wireless earphone is full, or to control the second switch 321 to be turned on with the second power supply assembly 36 in the case that it is determined that the wireless earphone is not full.

The microcontroller 33 is further configured to control the NFC controller to send a third notification message to the terminal to stop charging the terminal if it is determined that both the wireless headset and the headset case 30 are fully charged.

Fig. 4 is a flow chart of a wireless charging method according to an embodiment of the present application, which is applied to an earphone box, as shown in fig. 4, and the method at least includes the following steps:

in step S410, the electric energy transmitted by the NFC antenna set in the terminal is received through the NFC antenna set in the charging process.

Here, the NFC antenna group is disposed on a surface of the earphone box, and may include an NFC coil or the like.

Here, the terminal is a device with an NFC antenna, such as a smart phone, a notebook computer, a tablet computer, a palm internet device, a multimedia device, a streaming media device, a mobile internet device, a wearable device, or other types of devices.

Step S420, wirelessly charging the first power component and/or the second power component of the wireless headset with the power through the power management chip.

Wherein the first power supply assembly and the second power supply assembly may be a battery, or may include a battery and a charging IC.

Step S430, controlling, by the microcontroller, the power management chip to charge the first power component and/or the second power component.

In an implementation, a priority policy may be set to wirelessly charge the first power component or the second power component. For example, when the wireless earphone is contained in the earphone box and the earphone is not full, the wireless earphone is charged preferentially, and when the wireless earphone is not full of the earphone box or the wireless earphone is full of the electric quantity, the earphone box is charged.

Step S440, supplying power to the microcontroller through the first power supply assembly.

In other embodiments, the presence of a radio frequency field around the NFC antenna group is determined by an NFC controller prior to starting charging, a first notification message is sent by the NFC controller to the micro control component, and accordingly, the microcontroller controls a power management chip to charge the first power component and/or the second power component in response to the first notification message.

In other embodiments, the NFC antenna group comprises a first antenna group and a second antenna group, the first antenna group and the second antenna group comprise NFC coils and sensors, electromagnetic induction currents generated by the corresponding NFC coils are detected through the sensors, and second notification messages are sent to the microcontroller through the sensors.

The microcontroller responds to the second notification message, controls the NFC controller to be connected with the NFC coil of the first antenna group or the NFC coil of the second antenna group through the first switch, and controls the power management chip to be connected with the NFC coil of the first antenna group or the NFC coil of the second antenna group through the first switch, so that charging can be normally started when the terminal is close to any face of the earphone box.

In other embodiments, the first power component is wirelessly charged by using the power received by the NFC antenna through a first power output port of the power management chip, and the second power component is wirelessly charged by using the power received by the NFC antenna through a second power output port of the power management chip.

In other embodiments, it is detected whether the wireless headset is full of power before the first power component, and/or the second power component, is charged by the microcontroller controlling the power management chip. And controlling the second switch to be connected with the first power supply component under the condition that the microcontroller determines that the electric quantity of the wireless earphone is full, or controlling the second switch to be connected with the second power supply component under the condition that the microcontroller determines that the electric quantity of the wireless earphone is not full.

In other embodiments, in the case that it is determined that the earphone and the charging earphone box are both fully charged, the microcontroller controls the NFC controller to send a third notification message to the terminal, so that the terminal stops charging.

The wireless charging method described above is described below in connection with a specific embodiment, however, it should be noted that the specific embodiment is only for better illustrating the present application, and is not meant to be a undue limitation on the present application.

Bluetooth is a global standard for wireless data and voice communications, which is a special short-range wireless technology connection that establishes a communication environment for fixed and mobile devices based on low-cost short-range wireless connections. Bluetooth enables some portable mobile devices and computer devices today to connect to the internet without the need for cables and to have wireless access to the internet. A typical representative of this is a bluetooth headset, which allows the user to free himself from the annoying wires and to talk easily in various ways. Since the advent of bluetooth headsets, it has been a good tool for the mobile commerce family to increase efficiency.

The Bluetooth earphone is connected with the terminal in a wireless mode, and the common wearing mode is two modes, namely an in-ear mode and an on-ear mode. The operation modes of the Bluetooth headset are two currently mainstream modes, one is that the Bluetooth headset is realized by key combination when a user performs operations such as answering, hanging up, suspending, switching tracks and the like, and the user needs to lift hands to the ear headset. Another way is touch, i.e. changing keys to touch keys.

NFC (NEAR FIELD Communication) currently allows wireless charging of devices in small battery powered devices, such as many IoT (Internet of Things ) devices. The method may avoid providing a separate wireless charging unit for the small device if the device comprises an NFC communication interface. WLC (WIRELESS LAN Controller, wireless local area network Controller) specifications extend the communication functions of NFC technology to enable wireless charging. The WLC specification may ensure that a secure charging process is conducted between two NFC-enabled devices in a static or negotiated mode. The static mode uses standard RF (Radio Frequency) field strength and provides a consistent power level. The negotiation mode uses a higher rf field supporting four power transmission levels of 250, 500, 750, and 1000 milliwatts.

First, NFC wireless charging is described, where the NFC charging entity can be divided into two parts, WLC interrogator (Poller) and WLC listener (Listener). Fig. 5 is a system block diagram of an NFC charging scheme provided by an embodiment of the present application, as shown in fig. 5, the WLC interrogator is a Transmitter 51 (Transmitter) as an electric power output terminal, and the communication data and the electric power are transmitted to the WLC listener terminal through the NFC coil 52. The WLC monitor is divided into a Power Management unit 55 (Power Management) and a Communication unit 54 (Communication), wherein the Power Management unit 55 is mainly responsible for the Management of the rectified or externally rectified voltage and current and the battery 57 in the charging state, and the Communication unit 54 is mainly responsible for the Communication with the transmitter 51 through the NFC coil 53 to perform the negotiation of wireless charging. The power management unit 55 and the communication unit 54 operate in parallel without communication with each other, and both communicate unidirectionally with the microcontroller 56 through I2C and function as a Slave (Slave).

The embodiment of the application provides a charging method for realizing a Bluetooth headset by utilizing NFC wireless charging. The poller can be directly built in the terminal and can be compatible with the NFC of the existing terminal (namely, the terminal with NFC can charge the Bluetooth headset). The design of the coil is particularly important for the whole NFC wireless charging. For the polling device end, the coil can be directly placed in the terminal because the space of the terminal is large enough, and for the monitor end, the coil can be directly placed on the Bluetooth earphone side, but considering the small size problem of the Bluetooth earphone and the independence problem of two earphones, two placement schemes are available at present, one is to place the coil in a Bluetooth earphone box, the two earphones share the coil design, and the other is an independent coil design.

The embodiment of the application mainly adopts a first scheme, namely, the design that the NFC coil is placed in the Bluetooth headset box, wherein the front surface and the back surface of the Bluetooth headset box are respectively provided with an NFC coil, and each coil on each surface is provided with a Hall sensor for detecting which surface of the Bluetooth headset is being approached by the terminal NFC coil, so that the function of wireless charging of the front surface and the back surface of the Bluetooth headset box is realized.

When the hall sensor at one side detects that the terminal coil is close, the microcontroller is informed immediately, and the microcontroller immediately switches the first switch, so that the NFC controller and the power management chip can be connected with the charging coil for communication and energy acquisition, and after the power management chip acquires energy, the earphone box or the earphone battery can be charged. In practice, the method comprises the following steps:

The first step, two hall sensors are used for detecting whether a terminal is close, and if a certain side detects that the terminal is close, the microcontroller is immediately informed.

And secondly, immediately informing the first switch to the NFC coil at the corresponding side after the microcontroller receives the terminal approach notification.

After the NFC controller turns on the coil, it can detect whether the NFC coil and the radio frequency field exist on the terminal. If the NFC radio frequency field exists, the microcontroller is informed to start charging, if the NFC radio frequency field does not exist, the microcontroller is informed to fix the coil in the switch state to be unchanged, and whether the NFC radio frequency field exists or not is continuously detected periodically. Until the hall sensor detects the departure of the terminal.

And thirdly, if the microcontroller receives a notification of starting charging, the microcontroller needs to detect whether the Bluetooth headset is in the headset box at the moment.

Fourth, if the Bluetooth headset is in the headset box, the microcontroller detects whether the headset electric quantity is full.

If the earphone is full, the second switch is controlled to charge the earphone box battery; if the Bluetooth earphone is not full, the Bluetooth earphone is charged first, and then the Bluetooth earphone is switched to the earphone box battery for charging after the Bluetooth battery is full, and if the earphone box battery and the Bluetooth battery are full, the NFC controller informs the terminal end to stop charging.

And fifthly, if the Bluetooth headset is not in the headset box, directly charging the battery of the headset box.

According to the embodiment of the application, the NFC coil with the front surface and the back surface for charging is designed firstly, a user does not need to distinguish the front surface and the back surface of the earphone box when using the NFC coil, and the related identification and judgment circuit is designed to flexibly switch the charging path, so that the NFC coil can be charged when being randomly placed on one surface of the earphone box. According to the embodiment of the application, the NFC wireless charging is utilized, so that any NFC terminal can charge the Bluetooth headset anytime and anywhere, a double-coil system is designed, and the use experience of a user is improved.
