Embodiment Construction

[0014] The present invention provides an NFC terminal compatible with a metal back shell and a plastic back shell, through the design that the NFC antenna of the metal back shell and the NFC antenna of the plastic back shell share the same circuit board. Mainly the hardware circuit board is compatible with different NFC antennas.

[0015] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] see figure 1 , The NFC terminal compatible with the metal back shell and the plastic back shell provided by the present invention includes a main board (not shown in the figure) and a back shell (not shown in the figure), and the back shell is a metal back...

Abstract

The invention discloses an NFC (Near Field Communication) terminal compatible with a metal rear shell and a plastic rear shell. The NFC terminal comprises a main board and a rear shell, wherein the rear shell is a metal rear shell or a plastic rear shell; the metal rear shell is provided with a first NFC antenna, the plastic rear shell is provided with a second NFC antenna, and the main board is provided with an NFC module, a first matching circuit for matching the first NFC antenna and a second matching circuit for matching the second NFC antenna. The first matching circuit and the second matching circuit are simultaneously designed on the NFC terminal, when the NFC terminal is connected with the metal rear shell, a control signal outputted by the NFC module is transmitted outwards successively through the first matching circuit and the first NFC antenna, and when the NFC terminal is connected with the plastic rear shell, the control signal outputted by the NFC module is transmitted outwards successively through the second matching circuit and the second NFC antenna, so that the main board of the NFC terminal is simultaneously compatible with the metal rear shell and the plastic rear shell so as to realize the NFC function.

Description

technical field [0001] The invention relates to an electronic terminal, in particular to an NFC terminal compatible with a metal back shell and a plastic back shell. Background technique [0002] Because mobile phones and other devices with NFC function can be configured with metal back shells, plastic back shells can also be configured, and metal back shells and plastic back shells need to be designed with different NFC antennas and different matching circuits. In order to improve the user experience, users may be equipped with metal and non-metal back shells at the same time. This will lead to the need to design different NFC antennas, so the main board of the terminal also needs different matching circuits to match different antenna performances. In this way, the same device cannot share different back shells. In view of this, the present invention provides an NFC terminal compatible with metal back shells and plastic back shells.
