Abstract

Disclosed is an electromagnetic-interference-resistant terminal including a mobile-terminal body, an FPC arranged on the mobile-terminal body and a shoulder microphone used for being connected with an external device. The mobile-terminal body is connected with the shoulder microphone through the FPC. The interface FPC includes a signal-wire layer and host formations distributed at the two sides of the signal-wire layer. Signal wires of the shoulder microphone are connected with the signal-wire layer. The host formations at the two sides guide electromagnetic waves of the signal-wire layer into formations of the mobile-terminal body. A layer of magnetic ring is sleeved at an interface of the shoulder microphone. The magnetic ring is used for eliminating part of the electromagnetic waves coupled with the shoulder microphone. Through adding the magnetic ring at an end of a cabled peripheral (such as the shoulder microphone), close to the interface, and carrying out shielding processing on the interface FPC, demagnetization through the magnetic ring and shielding can be carried out so that electromagnetic-compatibility problems caused by a transmitting antenna on the cabled peripheral can be reduced greatly.

Description

technical field [0001] The invention relates to a terminal device, in particular to a terminal with wired peripherals that is resistant to electromagnetic interference. Background technique [0002] When the antenna of the wireless terminal is transmitting, the external peripherals couple the electromagnetic wave emitted by the antenna, and then import it into the PCB board through the external interface of the terminal. As a result, electromagnetic interference inside the terminal occurs, causing problems such as slow response and crash of the terminal. [0003] In order to avoid this problem, the prior art is forced to choose to use wireless peripherals, or reduce the transmit power of the wireless terminal, so as to reduce the impact of antenna radiation on the terminal. Contents of the invention [0004] The present invention provides an anti-electromagnetic interference terminal, which is characterized in that it includes a mobile terminal body, an FPC disposed on t...
