Problems solved by technology

[0003] However, at present, most manufacturers choose to add an NFC antenna to the back cover of the user equipment. The first problem is that if the shell of the user equipment is a metal shell, since the metal material will shield the magnetic field, the metal shell will shield the magnetic field generated by the NFC antenna. , which will reduce the performance of the NFC antenna; in addition, adding an NFC antenna to the back cover will increase the thickness of the user equipment and affect the user experience

Embodiment Construction

[0032] In the embodiment of the present invention, refer to figure 1 As shown, when the electronic device is performing NFC communication (such as NFC payment), when the NFC terminal card reader included in the electronic device, for example, when the magnetic induction coil passes through a changing current, an induced magnetic field will be generated around the electronic device, According to Faraday's law of electromagnetic induction, the induced magnetic field can affect the change of the current on the magnetic induction coil, thereby transmitting corresponding information.

[0033] In the prior art, since the magnetic field generated by the NFC antenna 102 will form an eddy current in the metal housing 101, and the direction of the magnetic field of the eddy current is opposite to the direction of the magnetic field generated by the NFC antenna 102, which will weaken the magnetic field formed by the NFC antenna 102, that is The metal shell 101 can shield the magnetic fie...

Abstract

The invention discloses electronic equipment, and the electronic equipment comprise a first coil and an NFC (Near Field Communication) chip; the first coil is located at a quiet zone of the electronicequipment, and a winding direction of the first coil is a non-thickness direction of the electronic equipment; and the NFC chip is communicated with the first coil and used for receiving and transmitting NFC signals.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an electronic device. Background technique [0002] In the past two years, the near field communication technology (Near Field Communication, NFC) used for the payment function has been gradually applied to the user equipment. NFC is an integration of non-contact radio frequency identification and Internet technology. The NFC antenna mounted inside the user device uses magnetic field coupling to communicate with the card reader loaded with the coil. [0003] However, at present, most manufacturers choose to add an NFC antenna to the back cover of the user equipment. The first problem is that if the shell of the user equipment is a metal shell, since the metal material will shield the magnetic field, the metal shell will shield the magnetic field generated by the NFC antenna. , which will reduce the performance of the NFC antenna; in addition, adding an NFC antenna to the b...
