[0051] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0052] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] It should be noted that the user information involved in this disclosure (including but not limited to user device information, user personal information, etc.) is all information authorized by the user or fully authorized by all parties.

[0054] Figure 1 FIG. 1 is a structural diagram of a vibration circuit according to an exemplary embodiment. Figure 1 As shown, the near field communication NFC module vibration circuit includes: an NFC module 1, a magnetic core 2, a processor module 3, and a motor drive module 5;

[0055] The magnetic core 2 is disposed in the middle area of ​​the NFC module 1 .

[0056] Traditional antennas transmit electromagnetic signals by radiating electromagnetic waves into the air. In order to radiate electromagnetic signals into the air, the length of the antenna needs to be comparable to the working wavelength. The length of a simple half-wave dipole antenna is 1 / 2 wavelength, and the length of a monopole antenna is 1 / 4 wavelength. Corresponding to the operating frequency of 13.56MHz, the size of a half-wave dipole antenna is 11.06m, and the size of a monopole antenna is 5.03m. In this embodiment, the NFC module 1 transmits electromagnetic signals through near-field coupling, and the antenna working distance is much smaller than that of a traditional antenna.

[0057] Optionally, the NFC module 1 includes at least one NFC coil. The NFC module 1 can be regarded as a coupled coil. According to Ampere's law, when current flows through a section of wire, a magnetic field will be generated around the conductor, and the magnetic field induction intensity is proportional to the number of coil turns and the coil area, and decays with the cube of the distance. According to Faraday's law of electromagnetic induction, a time-varying magnetic field passing through a closed space will generate an induced voltage. Therefore, these two laws are applied to the NFC reader and NFC card respectively. The reader antenna generates a magnetic field that is coupled to the NFC card antenna to generate voltage energy to activate the chip in the NFC card, thereby transmitting energy and signals.

[0058] Optionally, the motor driving module 5 is used to output a driving signal to the NFC module 1 , and the NFC module 1 is used to generate a current according to the driving signal and to generate a relative displacement with the magnetic core 2 to generate vibration.

[0059] The NFC module 1 alone cannot realize the vibration function. In this embodiment, a magnetic core 2 is added. The relative position of the magnetic core 2 and the mobile phone housing is fixed, that is, the magnetic core 2 is installed in a fixed position in the mobile phone and will not move relative to the mobile phone. In this way, when a specific alternating current is input into the NFC module 1, the magnetic field generated in the NFC module 1 interacts with the magnetic field of the magnetic core 2, and the NFC module 1 can move relative to the magnetic core 2 to achieve a vibration effect.

[0060] Optionally, the magnetic core 2 is disposed at the center of the NFC module 1, for example, at the center point of the NFC module 1. It should be noted that the embodiment of the present disclosure does not specifically limit the location of the magnetic core 2.

[0061] Optionally, the shape of the magnetic core includes any one of the following: a cylinder, a cuboid, and a cube. It should be noted that the present disclosure does not specify the shape of the magnetic core, and the shape of the magnetic core can be adjusted according to actual needs.

[0062] The output end of the processor module 3 is connected to the input end of the motor driving module 5 , and the processor module 3 can output a control signal to the motor driving module 5 so that the motor driving module 5 outputs the driving signal.

[0063] Figure 2 FIG. 1 is a structural diagram of a vibration circuit according to an exemplary embodiment. Figure 2 As shown, the vibration circuit of the near field communication NFC module Figure 1 The modules in the embodiment also include: a switching module 6 and a radio frequency signal transceiver module 4.

[0064] The switching module 6 includes a first input terminal, a second input terminal, a control terminal and an output terminal. The circuit connected between the first input terminal and the output terminal is a first path, the circuit connected between the second input terminal and the output terminal is a second path, the first input terminal is connected to the output terminal of the motor driving module 5, and the output terminal is connected to the input terminal of the NFC module 1. It should be noted that the number of ports of the switching module 6 can be set according to functional requirements, etc., and the present disclosure can adjust the first input terminal, the second input terminal, the control terminal and the output terminal of the switching module 6 according to requirements.

[0065] Optionally, the output end of the processor module 3 is connected to the control end of the switching module 6, and the switching module 6 is used to control the first path and the second path to enter the disconnected state or the open state according to the switching instruction input by the control end.

[0066] The output end of the processor module 3 is connected to the input end of the radio frequency signal transceiver module 4 , and the output end of the radio frequency signal transceiver module 4 is connected to the first input end of the switch module 6 .

[0067] In this embodiment, the radio frequency signal transceiver module 4 is used to perform NFC communication using the NFC module 1, and the motor drive module 5 is used to control the NFC module 1 to generate vibration. Since there is only one NFC module 1 in the mobile phone, NFC communication and vibration cannot be performed at the same time, so a switching module 6 is set to decide whether to send the signal input by one of the above two modules to the NFC module 1 to control the function performed by the NFC module 1.

[0068] In NFC communication, there are two communication modes: active mode and passive mode.

[0069] In the active mode, the first path is in an open state and the second path is in a disconnected state, the RF signal transceiver module 4 is used to receive the control signal sent by the processor module 3, and send a RF induction signal to the first input end of the switching module 6; the NFC module 1 is used to generate a RF field according to the RF induction signal to identify an external NFC device, and read or write information to the external NFC device.

[0070] In this embodiment, the control signal sent to the RF signal transceiver module 4 is used to instruct NFC communication. The RF signal transceiver module 4 can generate a RF induction signal according to the control instruction. The NFC module 1 can generate a RF field (Radio Frequency Field, RF Field) according to the RF induction signal to perform NFC communication with other NFC devices, identify NFC devices and read / write data.

[0071] In the passive mode, the first path is in an open state and the second path is in a disconnected state, and the NFC module 1 is used to passively respond to the radio frequency field emitted by the external NFC device to accept reading or writing by the external NFC device; the radio frequency signal transceiver module 4 is used to receive information that the NFC module is read and / or written by the external NFC device, and send it to the processor module 3.

[0072] The two modes of NFC communication are as follows:

[0073] Active mode: This device acts as the initiator of NFC communication and generates a radio frequency field through NFC module 1. The target device does not generate a radio frequency field. This device can identify the target device or read / write data in the receiving device.

[0074] Passive mode: As a passive receiver, this device does not need to generate a radio frequency field. The target device generates a radio frequency field, and this device is read / written by the target device. This device uses load modulation technology to transmit data back to the target device at the same speed.

[0075] This device can switch between NFC communication modes. When the battery is sufficient, the processor module 3 can control the device to be in active mode or two-way mode. When the battery is low, the processor module 3 can control the device to be in passive mode. This can greatly reduce power consumption and extend the battery life of the device.

[0076] Optionally, the control signal sent to the motor driving module 5 is used to instruct the generation of vibration. The motor driving module 5 generates a driving signal according to the control signal. After the driving signal is input into the NFC module 1, the NFC module 1 can generate a magnetic field and interact with the magnetic field of the magnetic core 2, so that the NFC module 1 is displaced to generate a vibration effect.

[0077] In a possible embodiment, the driving signal may be a pulse current that has undergone half-wave rectification. It should be noted that the present disclosure does not specifically limit the type of the driving signal.

[0078] Optionally, in a vibration scenario, the switching module controls the first path to be in a disconnected state and the second path to be in an open state according to the switching signal sent by the processor module, and the motor driving module is used to output a driving signal to the second input end of the switching module.

[0079] In this embodiment, in a vibration scenario, the NFC module 1 is required to perform the function of generating vibration. The switching module 6 controls the first input terminal to be in a disconnected state and the second input terminal to be in an on state according to the switching signal sent by the processor module 3. The NFC module 1 generates a current according to the driving signal and generates a relative displacement with the magnetic core 2 to generate vibration.

[0080] Optionally, the processor module 3, the RF signal transceiver module 4 and the motor drive module 5 include one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components.

[0081] Optionally, the device further comprises a memory configured to store various types of data to support operations in the device. Examples of such data include instructions for any application or method operating on the device, contact data, phone book data, messages, pictures, videos, etc. The memory may be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic disk or optical disk.

[0082] Optionally, the device includes a power supply component that provides power to various components in the device. The power supply component may include a power management system, one or more power supplies, and other components associated with generating, managing, and distributing power for the device.

[0083] Optionally, the device may operate based on an operating system stored in the memory, such as Windows Server™, Mac OS X™, Unix™, Linux™, FreeBSD™ or the like.

[0084] Figure 3 is a flow chart of a control method according to an exemplary embodiment. Figure 3 As shown, the near field communication NFC module vibration circuit method is applied to the switching module 6, including:

[0085] Step 301, obtaining the working mode selected by the user, and sending a switching instruction to the switching module according to the working mode;

[0086] In this embodiment, the user can select the working mode of the NFC module in the vibration circuit based on the application scenario, and control the working mode of the NFC module by sending a switching instruction to the switching module.

[0087] In a possible embodiment, the processor determines the application scenario and selects the corresponding working mode to send a switching instruction to the switching module. For example, when a user opens the functions such as transportation card and bank card in the mobile wallet application, it can be determined that the passive mode needs to be entered to allow other NFC devices to read information.

[0088] When the user turns on the card reading, card writing and other functions in the mobile phone, it can be determined that the active mode needs to be entered to read or write information to other NFC devices.

[0089] When the user opens a game application, a video application, or a music application, it may be determined that the vibration mode needs to be entered to cause the NFC to vibrate.

[0090] Step 302: Control the states of the first path and the second path in the switching module according to the switching instruction, wherein the states include an open state and a disconnected state.

[0091] In this embodiment, by controlling the states of the first path and the second path in the switching module, the signal entering the NFC module after passing through the switching module is controlled, so as to achieve the goal of controlling the working mode of the NFC module.

[0092] Step 303: communicate with the NFC module according to the opened path, so that the NFC module enters a corresponding working mode.

[0093] In this embodiment, the path in the open state can transmit information, and the path in the disconnected state cannot transmit information, so the NFC module can only receive information transmitted in the path in the open state to achieve the corresponding working mode.

[0094] Optionally, the working mode includes any one of the following: active mode; passive mode; vibration mode.

[0095] In this embodiment, in active mode, the NFC module actively generates a radio frequency field to communicate with an external NFC device and performs read / write operations on the external NFC device; in passive mode, the NFC module passively senses the radio frequency field generated by the external NFC device and accepts read / write operations from the external NFC device; in vibration mode, the NFC module receives input current to generate a magnetic field, and interacts with the magnetic field of the magnetic core to generate vibration.

[0096] In a possible embodiment, when using the NFC module to perform functions such as swiping a card to pay, swiping a card to open a door, and swiping a card to board a bus, the NFC module needs to enter a passive mode so that information can be read or written by other NFC devices.

[0097] In a possible embodiment, when using the NFC module to perform functions such as reading card information and transmitting data, the NFC module needs to enter an active mode, and the NFC module generates a radio frequency field and reads or writes information to other NFC devices.

[0098] In a possible embodiment, when a user runs a game application, a video application, or a music application on a mobile phone, it is necessary to enable the NFC module to enter a vibration mode to generate vibration according to a preset scheme of the application.

[0099] Optionally, when the working mode is an active mode or a passive mode, controlling the states of the first path and the second path in the switching module according to the switching instruction includes:

[0100] The first path is controlled to enter an open state, and the second path is controlled to enter a disconnected state.

[0101] In this embodiment, the first path is connected to the radio frequency signal transceiver module, and NFC communication can be performed with the NFC module through the first path.

[0102] Optionally, when the working mode is an active mode, the communication with the NFC module according to the path in the open state so that the NFC module enters a corresponding working mode includes:

[0103] The radio frequency induction signal sent by the radio frequency signal transceiver module is input into the NFC module through the first path, and the NFC module generates a radio frequency field according to the radio frequency induction signal, so that the NFC module identifies an external NFC device and reads or writes information to the external NFC device.

[0104] Optionally, when the working mode is a passive mode, the communication with the NFC module according to the path in the open state so that the NFC module enters a corresponding working mode includes:

[0105] The NFC module is enabled to passively respond to the radio frequency field emitted by the external NFC device, receive the information read or written by the external NFC device, and send the information to the radio frequency signal transceiver module through the first path.

[0106] Optionally, when the working mode is the vibration mode, controlling the states of the first path and the second path in the switching module according to the switching instruction includes:

[0107] The first path is controlled to enter a disconnected state, and the second path is controlled to enter an open state.

[0108] In this embodiment, the second path is connected to the motor driving module, and the motor driving module can output a specific current to the NFC module through the second path, so that the NFC module generates a magnetic field and interacts with the magnetic field of the magnetic core to generate vibration.

[0109] Optionally, the communicating with the NFC module according to the path in the open state so that the NFC module enters a corresponding working mode includes:

[0110] The driving signal output by the motor driving module is input to the NFC module through the second path, so that the NFC module vibrates according to the driving signal.

[0111] In an exemplary embodiment, a storage medium including instructions is also provided, such as a memory including instructions, and the instructions can be executed by the processor module to complete the above method. Optionally, the storage medium can be a non-temporary computer-readable storage medium, for example, the non-temporary computer-readable storage medium can be a ROM, a random access memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, etc.
