[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The following embodiments are used to illustrate the present application, but are not intended to limit the scope of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0028] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0029] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are merely to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0030] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those skilled in the art in the field to which the embodiments of the present application belong. It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with the meanings in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0031] Figure 1 A schematic diagram of the structure of an earphone box provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the earphone box 10 includes an NFC antenna group 11, a power management chip 12, a microcontroller 13 and a first power supply component 14.

[0032] The NFC antenna group 11 is used to receive the electric energy transmitted by the NFC antenna set in the terminal during the charging process;

[0033] a power management chip 12, electrically connected to the NFC antenna group 11, for wirelessly charging the first power component 14 and / or the second power component of the wireless headset using the electric energy; wherein the wireless headset is accommodated in the headset box 10 in a detachable manner;

[0034] A microcontroller 13, used for controlling the power management chip 12 to charge the first power component 14 and / or the second power component;

[0035] The first power supply component 14 is electrically connected to the power management chip 12 and is used to supply power to the microcontroller 13 .

[0036] The NFC antenna group 11 may include an NFC coil capable of generating magnetic field induction, which is arranged on the surface of the earphone box 10, so that when a terminal with an NFC antenna is close to the surface of the earphone box 10, the coil inside the NFC antenna group 11 generates an induced current, thereby realizing the transmission of electric energy from the terminal to the earphone box 10.

[0037] The power management chip 12 is mainly responsible for the management of the voltage and current after rectification or external rectification and the battery charging status. It can be a PMIC (Power Management IC), which is connected to 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. The power management chip 12 rectifies the electric energy and converts it into a suitable charging voltage, so as to charge the first power supply component 14, that is, the battery of the earphone box itself, or charge the second power supply component of the wireless earphone through the power output end of the power management chip 12.

[0038] It is understandable that the wireless earphone can be detached from the earphone box 10 for easy use by the user. The wireless earphone can be a Bluetooth earphone, an infrared earphone, or a wireless earphone connected by other wireless means.

[0039] The microcontroller 13 is a MCU (Microcontroller Unit). During implementation, when the earphone box is in the radio frequency field generated by the terminal, the power management chip 12 can be controlled to start the charging process.

[0040] The first power source assembly 14 may include only a secondary battery, or the first power source assembly 14 may include a secondary battery and a charging IC.

[0041] In the embodiment of the present application, the NFC antenna group is used to receive the power transmitted by the NFC antenna set in the terminal, and the first power component and / or the second power component of the wireless headset are wirelessly charged through the power management chip, so that the headset box can obtain the power of the external terminal through the NFC antenna group, realize the wireless charging of its own first power component, or the wireless headset contained in the headset box, so that any terminal can charge the wireless headset anytime and anywhere. Using NFC wireless charging to directly charge the wireless headset can improve the power conversion efficiency and avoid the disadvantage that the wireless headset cannot be charged when the headset box is out of power.

[0042] Figure 2 A schematic diagram of the structure of another earphone box provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the earphone box 20 includes, in addition to the NFC antenna group 21, the power management chip 22, the microcontroller 23 and the first power supply component 24, an NFC controller 25. The NFC controller 25 is electrically connected to the NFC antenna group 21, and is used to send a first notification message to the microcontroller 23 when it is determined that there is a radio frequency field around the NFC antenna group 21; accordingly, the microcontroller 23 is also used to respond to the first notification message and control the power management chip 22 to charge the first power supply component 24 and / or the second power supply component of the wireless headset.

[0043] The NFC controller 25 is mainly responsible for communicating with the NFC antenna of the terminal through the NFC antenna group 21 to negotiate wireless charging. The NFC controller 25 and the power management chip 22 work in parallel without mutual communication. Both communicate with the microcontroller 23 in a one-way manner through I2C.

[0044] The NFC controller 25 can detect whether there is an NFC antenna in the terminal close to the earphone box 20, and whether there is an NFC radio frequency field around the earphone box. Usually, the NFC antenna on the terminal transmits a radio frequency signal. When the terminal is close to the earphone box, the NFC antenna in the earphone box generates an induced current, so that the NFC controller detects the presence of the NFC radio frequency field.

[0045] If the NFC controller 25 detects the presence of an NFC radio frequency field, it notifies the microcontroller 23 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.

[0046] If the NFC controller 25 does not detect the existence of the NFC radio frequency field, it will periodically continue to detect whether there is an NFC radio frequency field 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 a sensor).

[0047] The embodiment of the present application uses the NFC controller in the earphone box to wirelessly communicate with a terminal close to the earphone box, and detects whether there is an NFC radio frequency field around the earphone box, thereby ensuring a safe charging process between the terminal and the earphone box and improving charging efficiency.

[0048] In another embodiment, the NFC antenna group includes a first antenna group, a second antenna group and a first switch; wherein the first antenna group and the second antenna group are relatively arranged on the surface of the earphone box, and the first antenna group and the second antenna group both include an NFC coil and a sensor.

[0049] Figure 3A A schematic diagram of the structure of another earphone box provided in an embodiment of the present application is shown in FIG. Figure 3A As shown, the NFC antenna group includes an NFC coil 311, an NFC coil 312, a sensor 313, a sensor 314 and a first switch 315, wherein the NFC coil 311 and the sensor 313 serve as a first antenna group, and the NFC coil 312 and the sensor 314 serve as a second antenna group.

[0050] like Figure 3B As shown, the sensor 313 is set on the front side (current visual direction) of the earphone box 30, and the sensor 314 is set on the back side (opposite to the current visual direction) of the earphone box 30, which can be a Hall sensor, wherein: the sensor 313 is used 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 of the terminal is approaching; the sensor 314 is used 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 of the terminal is approaching. Thus, when the terminal approaches any side of the earphone box, the radio frequency field can be detected and the charging process can be started.

[0051] After receiving the second notification message sent by the sensor 313, the microcontroller 33 controls the NFC controller 35 to connect to 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 connect to the NFC coil 311 of the first antenna group or the NFC coil 312 of the second antenna group through the first switch 315, thereby realizing the function of wireless charging on both sides of the earphone box.

[0052] The first switch 315 and the second switch 321 can be MOS switches or triode switches.

[0053] In some embodiments, the first power output port of the power management chip 32 is connected to the first power component 34 through the second switch 321, so as to wirelessly charge the first power component 34 using the power received by the NFC antenna group; the 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, so as to wirelessly charge the second power component 36 using the power received by the NFC antenna group. The power management chip 32 is connected to the first power component 34 and the second power component 36 respectively through the two power output ports, so as to ensure that the appropriate voltage is output to the corresponding power components.

[0054] The first power source assembly 34 and the second power source assembly 36 may include only a battery, or the first power source assembly 34 and the second power source assembly 36 may include a battery and a charging IC.

[0055] Before the microcontroller 33 controls the power management chip 32 to charge the first power component 34 and / or the second power component 36 , the microcontroller 33 is also used to respond to the first notification message and detect whether the wireless headset is accommodated in the headset box 30 .

[0056] It should be noted that when the wireless earphone is accommodated in the housing of the earphone box, the positive contact of the wireless earphone is docked with the positive contact of the earphone box, and the negative contact of the wireless earphone is docked with the negative contact of the earphone box, so that the earphone box can wirelessly charge the wireless earphone and communicate with the wireless earphone through the positive contact of the wireless earphone. For example, the earphone box and the wireless earphone can realize forced Bluetooth pairing, wireless earphone power query, switch box action notification, over-the-air download upgrade trigger, etc.

[0057] When the wireless headset is accommodated in the headset box 30, the microcontroller 33 is also used to control the second switch 321 to be connected to the first power supply component 34 when it is determined that the wireless headset is fully charged; or, when it is determined that the wireless headset is not fully charged, control the second switch 321 to be connected to the second power supply component 36.

[0058] The microcontroller 33 is also used to control the NFC controller to send a third notification message to the terminal when it is determined that the wireless headset and the headset box 30 are fully charged, so that the terminal stops charging.

[0059] Figure 4 A flow chart of a wireless charging method provided in an embodiment of the present application is applied to an earphone box, such as Figure 4 Said method at least comprises the following steps:

[0060] Step S410: receiving electric energy transmitted by an NFC antenna set in the terminal during charging through the NFC antenna group.

[0061] Here, the NFC antenna group is set on the surface of the earphone box and may include an NFC coil, etc.

[0062] Here, the terminal is a device with an NFC antenna, such as a smart phone, a laptop, a tablet computer, a handheld Internet device, a multimedia device, a streaming media device, a mobile Internet device, a wearable device or other types of devices.

[0063] Step S420: wirelessly charge the first power component and / or the second power component of the wireless headset using the electrical energy through the power management chip.

[0064] Here, the wireless earphone is accommodated in the earphone box in a detachable manner.

[0065] Here, the power management chip is electrically connected to the NFC antenna group, directly obtains the power received by the NFC antenna group, and outputs a suitable voltage of the first power component or the second power component after rectifying the power. The first power component and the second power component may be batteries, or may include batteries and charging ICs.

[0066] Step S430, controlling the power management chip to charge the first power component and / or the second power component through the microcontroller.

[0067] During the implementation process, a priority strategy can be set to wirelessly charge the first power component or the second power component. For example, if the earphone box contains a wireless earphone and the earphone is not fully charged, the wireless earphone is charged first; if the wireless earphone is not in the earphone box or the wireless earphone is fully charged, the earphone box is charged.

[0068] Step S440: supply power to the microcontroller via a first power supply assembly.

[0069] In the embodiment of the present application, the NFC antenna group is used to receive the power transmitted by the NFC antenna set in the terminal, and the first power component and / or the second power component of the wireless headset are wirelessly charged through the power management chip, so that the headset box can obtain the power of the external terminal through the NFC antenna group, realize the wireless charging of its own first power component, or the wireless headset contained in the headset box, so that any terminal can charge the wireless headset anytime and anywhere. Using NFC wireless charging to directly charge the wireless headset can improve the power conversion efficiency and avoid the disadvantage that the wireless headset cannot be charged when the headset box is out of power.

[0070] In other embodiments, before starting charging, the NFC controller determines whether a radio frequency field exists around the NFC antenna group; the NFC controller sends a first notification message to the microcontroller component; accordingly, the microcontroller controls the power management chip to charge the first power component and / or the second power component in response to the first notification message.

[0071] In other embodiments, the NFC antenna group includes a first antenna group and a second antenna group; the first antenna group and the second antenna group both include an NFC coil and a sensor, and the electromagnetic induction current generated by the corresponding NFC coil is detected by the sensor; and the second notification message is sent to the microcontroller through the sensor.

[0072] In response to the second notification message, the microcontroller controls the NFC controller to connect to 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 connect to 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 started normally when the terminal is close to either side of the earphone box.

[0073] In other embodiments, the first power supply component is wirelessly charged using the power received by the NFC antenna through the first power output port of the power management chip; and the second power supply component is wirelessly charged using the power received by the NFC antenna through the second power output port of the power management chip.

[0074] In other embodiments, before the microcontroller controls the power management chip to charge the first power component and / or the second power component, it is detected whether the wireless headset is fully charged. When the microcontroller determines that the wireless headset is fully charged, the second switch is controlled to be connected to the first power component; or when the microcontroller determines that the wireless headset is not fully charged, the second switch is controlled to be connected to the second power component.

[0075] In other embodiments, when it is determined that the earphone and the charging earphone box are fully charged, the microcontroller controls the NFC controller to send a third notification message to the terminal to stop charging the terminal.

[0076] The above wireless charging method is described below in conjunction with a specific embodiment. However, it is worth noting that this specific embodiment is only for better illustrating the present application and does not constitute an improper limitation on the present application.

[0077] Bluetooth technology is an open global specification for wireless data and voice communications. It is a special short-range wireless technology connection based on low-cost short-range wireless connections to establish a communication environment for fixed and mobile devices. Bluetooth enables some of today's portable mobile devices and computer devices to connect to the Internet without cables and can access the Internet wirelessly. A typical example of this is the Bluetooth headset, which allows users to avoid the entanglement of annoying wires and make calls in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business people to improve efficiency.

[0078] Bluetooth headsets are connected to the terminal wirelessly, and there are two general ways to wear them: in-ear and over-ear. There are currently two mainstream ways to operate Bluetooth headsets. One is the button-type, where users need to raise their hands to the earphones to press a button combination to answer, hang up, pause, switch tracks, etc. The other is the touch-type, which replaces the button with a touch-type button.

[0079] Currently, NFC (Near Field Communication) allows wireless charging of small battery-powered devices, such as those in many IoT (Internet of Things) devices. If the device includes an NFC communication interface, this method can avoid providing a separate wireless charging unit for small devices. The WLC (Wireless LAN Controller) specification extends the communication capabilities of NFC technology to enable wireless charging. The WLC specification ensures a safe charging process between two NFC-enabled devices in static or negotiated mode. Static mode uses standard RF (Radio Frequency) field strength and provides consistent power levels. Negotiation mode uses a higher RF field and supports four power transfer levels of 250, 500, 750 and 1000 milliwatts.

[0080] First, let me introduce NFC wireless charging. NFC charging as a whole can be divided into two parts, the WLC poller (Poller) and the WLC listener (Listener). Figure 5 A system block diagram of the NFC charging solution provided in the embodiment of the present application, such as Figure 5As shown, the WLC poller is a transmitter 51 (Transmitter), which serves as an electric energy output terminal and transmits communication data and electric energy to the WLC listener terminal through the NFC coil 52. The WLC listener is divided into two parts: a power management unit 55 (Power Management) and a communication unit 54 (Communication). The power management unit 55 is mainly responsible for the management of the voltage and current after rectification or external rectification and the charging state of the battery 57. The communication unit 54 is mainly responsible for communicating with the transmitter 51 through the NFC coil 53 to negotiate wireless charging. The power management unit 55 and the communication unit 54 work in parallel without mutual communication. Both communicate with the microcontroller 56 in a one-way manner through I2C and act as slaves.

[0081] The embodiment of the present application provides a method for charging a Bluetooth headset using NFC wireless charging. The poller can be directly built into the terminal and can be compatible with the NFC of existing terminals (that is, any terminal with NFC can charge the Bluetooth headset). For the entire NFC wireless charging, the design of the coil is particularly important. For the poller end, because the terminal space is large enough, the coil can be placed directly in it; for the listener end, it can be placed directly on the Bluetooth headset side, but considering the small size of the Bluetooth headset and the independence of the two headsets, there are currently two placement solutions, one is to place the coil in the Bluetooth headset box, and the two headsets share the coil design, and the other is an independent coil design.

[0082] The embodiment of the present application is mainly the first solution, that is, the design in which the NFC coil is placed in the Bluetooth headset box. There is an NFC coil on the front and back of the Bluetooth headset box, and there is a Hall sensor at the coil on each side to detect which side of the Bluetooth headset the terminal NFC coil is close to, thereby realizing the function of wireless charging on both the front and back sides of the Bluetooth headset box.

[0083] When the Hall sensor on one side detects that the terminal coil is approaching, it immediately notifies the microcontroller, and the microcontroller immediately switches the first switch, so that the NFC controller and the power management chip can connect with the charging side coil to communicate and obtain energy. After the power management chip obtains energy, it can choose to charge the earphone box or the earphone battery. In implementation, the following steps are included:

[0084] In the first step, two Hall sensors are used to detect whether a terminal is approaching. If a terminal is detected approaching on one side, the microcontroller is notified immediately.

[0085] In the second step, after receiving the notification that the terminal is approaching, the microcontroller immediately notifies the first switch to switch to the NFC coil on the corresponding side.

[0086] At this time, after the NFC controller is connected to the coil, it can detect whether there is an NFC coil and a radio frequency field on the terminal. If so, it notifies the microcontroller to start charging. If the NFC radio frequency field is not detected, it notifies the microcontroller to fix the coil in this switch state and keep checking periodically whether there is a radio frequency field. Until the Hall sensor detects that the terminal has left.

[0087] In the third step, if the microcontroller receives a notification to start charging, the microcontroller needs to detect whether the Bluetooth headset is in the headset box at this time.

[0088] In the fourth step, if the Bluetooth headset is in the headset box, the microcontroller detects whether the headset is fully charged.

[0089] If it is full, the second switch is controlled to charge the earphone box battery; if it is not full, the Bluetooth headset is charged first, and then the charging of the earphone box battery is switched after the Bluetooth battery is fully charged; if both the earphone box battery and the Bluetooth battery are fully charged, the terminal is notified through the NFC controller to stop charging.

[0090] Step 5. If the Bluetooth headset is not in the headset box, charge the battery of the headset box directly.

[0091] The embodiment of the present application first designs a set of NFC coils for charging on both sides, so that users do not need to distinguish between the front and back sides of the earphone box when using it, and designs relevant identification and judgment circuits to flexibly switch the charging path, so that it can be charged by randomly placing it on one side of the earphone box. The embodiment of the present application uses NFC wireless charging, so that any NFC terminal can charge the Bluetooth headset anytime and anywhere, and designs a dual-coil system to improve the user experience.
