The electronic device 100 of the embodiment of the application can be applied to a mobile phone, a smart band, a tablet computer, a vehicle, a monitor, a security, a medical care, a game machine, a robot, and the like. Specifically, the electronic device 100 includes a housing 20 and a host 50, where the housing 20 includes a middle frame 22, a back shell 25 detachably mounted on the back of the middle frame 22, and a breathing lamp 27, and the breathing lamp 27 may be disposed on the back shell 25 or the middle frame 22; the host 50 includes a main board 52 disposed on the middle frame 22, a display screen 55 disposed on the front surface of the middle frame 22, an NFC module 57, and a power supply; the display screen 55 and the NFC module 57 are electrically connected to the motherboard 52, and the power supply is used for supplying power to the display screen 55 and the motherboard 52. The NFC module 57 of the electronic device 100 turns on the field to drive the on and off of the breathing lamp 27 on the housing 20. Specifically, as shown in fig. 4 and 5, the breathing lamp 27 includes an NFC antenna coil 271, a capacitor, and a light emitting diode L; the NFC antenna coil 271 is located in the electromagnetic field generated by the NFC module 57, two ends of the capacitor are respectively connected to two ends of the NFC antenna coil 271, and an anode and a cathode of the light emitting diode L are respectively electrically connected to two ends of the NFC antenna coil 271; the capacitor is used for tuning a resonance point of the NFC antenna coil 271 so that the NFC antenna coil 271 can be coupled to magnetic field energy generated by the NFC module 57, and the NFC antenna coil 271 is coupled to the magnetic field energy to generate a current to drive the light emitting diode L to emit light.

The NFC antenna coil 271 of the housing 20 of the electronic device 100 of this embodiment absorbs magnetic energy of a magnetic field around the electronic device 100, that is, the NFC antenna coil 271 absorbs magnetic energy generated by the NFC module 57 to generate a current, and the current supplies power to the light emitting diode L to make it emit light. Therefore, the breathing lamp 27 of the present application uses the magnetic field energy generated by the NFC module 57 to generate current through the NFC antenna coil 271 without an external battery, so as to turn on or off the light emitting diode L, and does not need to use a power supply of the electronic device 100 or a battery, which is energy-saving and environment-friendly; secondly, the whole scheme of the breathing lamp 27 is simple and the manufacturing cost is low; in addition, the breathing lamp 27 can control the light emitting diode L only by switching on and off the field of the NFC module 57, without requiring an additional communication protocol support, and without affecting the NFC module communication function of the electronic device 100.

The NFC refers to Near Field Communication (NFC for short), which is integrated and evolved from a non-contact radio frequency identification and interconnection technology, and electronic devices (such as smart phones) using Near Field Communication can exchange data when they are close to each other. By integrating the functions of an induction card reader, an induction card and point-to-point communication on a single chip, the electronic equipment is utilized to realize the applications of mobile payment, electronic ticketing, entrance guard, mobile identity recognition, anti-counterfeiting and the like. The "near field" of NFC refers to radio waves, i.e., electromagnetic waves, which are close to an electromagnetic field, so that it follows maxwell's equation, and the electric field and the magnetic field are alternately converted in energy all the time while propagating from a transmitting antenna to a receiving antenna, and are mutually enhanced when converted; within 10 wavelengths of electromagnetic waves, the electric field and the magnetic field are independent from each other, and the magnetic field can be used for short-distance communication, which is called near field communication. The NFC operation mode is divided into a passive mode and an active mode. The NFC initiator (i.e., the master) in the passive mode needs a power supply device, the master provides a radio frequency field by using energy of the power supply device and transmits data to the NFC target (i.e., the slave), and the transmission rate needs to be selected from one of 106kbps, 212kbps and 424 kbps. The slave device does not generate a radio frequency field, so that a power supply device is not required, and the radio frequency field generated by the master device is converted into electric energy to supply power to circuits of the slave device, receive data transmitted by the master device, and transmit the slave device data back to the master device at the same speed by using a load modulation technology.

Two ends of the NFC antenna coil 271 may be connected in parallel with a plurality of capacitors, that is, two ends of each capacitor are electrically connected to two ends of the NFC antenna coil 271 respectively. In this embodiment, the first capacitor C1 and the second capacitor C2 are connected in parallel to two ends of the NFC antenna coil 271, and the first capacitor C1 and the second capacitor C2 are used to tune a resonance point of the NFC antenna coil 271, so that the NFC antenna coil 271 can be coupled to magnetic field energy generated by the NFC module 57.

Preferably, the first and second capacitors C1 and C2 tune the resonance point of the NFC antenna coil 271 to around 13.56 MHz. Specifically, referring to fig. 6, fig. 6 is a schematic diagram of a waveform measured at two ends of the led L of the breathing lamp in fig. 4. The waveform measured across the led L is a 13.56MHz sine wave (period 74ns), and in the positive half of the sine wave, the led L will illuminate when the voltage is greater than the threshold voltage of the led L. By adjusting the first capacitor C1 and/or the second capacitor C2, Vpeak (peak level) can reach around 20V at maximum, the more energy the NFC antenna coil 271 is coupled to. According to the EMVCo (international chip card and payment technology standards organization) standard, the PCD (Proximity Coupling Device reader) field strength should be greater than 2.55V at 4 cm. The threshold voltage of the general light emitting diode is about 2V, for example, the red color is about 1.8V, the white color is about 2.5V, and so on, and therefore, the current generated by the NFC antenna coil 271 absorbing the magnetic field energy generated by the NFC module 57 can make the light emitting diode L emit light. That is, when the NFC antenna coil 271 receives the waveform of 13.56M, the light emitting diode L is in a state of being continuously turned on and off, and since the waveform period is only 74ns, human eyes cannot recognize that the light emitting diode L is in a blinking state, and only can see that the light emitting diode L is in a light emitting state all the time.

As shown in fig. 4, the NFC antenna coil 271 is formed by winding several turns of an enameled wire, and the several turns of the NFC antenna coil 271 are located on the same plane. The shape and the number of turns of the NFC antenna coil 271 may be designed as required; in this embodiment, the NFC antenna coil 271 is a rectangular coil, and the number of turns of the NFC antenna coil 271 is 4.

Specifically, the main board 52 controls the switching field of the NFC module 57 to turn on and off the light emitting diode L, and the main board 52 controls the magnitude of the electromagnetic field generated by the NFC module 57 to control the brightness of the light emitting diode L. If the mobile phone is in a standby state, the NFC module 57 will periodically open the field to control whether a card (card reader) is nearby; the time and the period of the field opening of the NFC module 57 can be controlled to set the on-off rule of the breathing lamp 27 on the housing 20, so as to realize the function of the breathing lamp 27; that is, the NFC module 57 turns on the field to radiate energy outwards, and the NFC antenna coil 271 receives the energy of the magnetic field of the NFC module 57 to generate current to drive the light emitting diode L to emit light, thereby implementing the function of the breathing lamp 27 of the mobile phone.

Therefore, more user differentiation settings can be realized, more differentiation selections can be provided for the user, and the user can conveniently recognize different prompts of the breathing lamp 27.

Specifically, the voltage value output by the NFC antenna coil 271 is changed by controlling the magnitude of the electromagnetic field energy generated by the NFC module, so as to drive the light-emitting diodes of different colors to turn on and turn off; if the voltage threshold value of the light-emitting diode is higher than the voltage value, the light-emitting diode does not emit light; if the voltage threshold value of the light-emitting diode is lower than the voltage value, the light-emitting diode can emit light.
