Abstract

The present invention discloses a shielding composite membrane including a magnetic conductive layer, multiple magnetic conductive convex blocks, a conductor layer and a conductive rubber layer. The multiple magnetic conductive convex blocks are installed on the magnetic conductive layer. The conductor layer is installed on the magnetic conductive convex blocks and is between the magnetic conductive convex blocks and the conductive rubber layer, multiple holes which are connected with each other are formed between the magnetic conductive layer, the conductive rubber layer and the bottoms of the magnetic conductive convex blocks.

Description

technical field [0001] The invention relates to a membrane, in particular to a shielding composite membrane. Background technique [0002] The operation of electronic devices (such as televisions, radios, computers, medical instruments, business machines, communication equipment, and the like) is accompanied by the generation of electromagnetic radiation from the electronic circuits of the electronic devices, which may radiate to other components in the electronic device components and interfere with them. This radiation typically develops as transients in the radio frequency band of the electromagnetic spectrum (ie, between about 10 KHz and 10 GHz), and is referred to as electromagnetic interference (EMI). [0003] In normal operation, electronic devices will generate electromagnetic energy released by radiation and conduction, which will affect the transmission of adjacent electronic devices. This electromagnetic interference (EMI) may cause attenuation or complete loss o...
