Title:
ELECTROMAGNETIC NOISE ABSORBER FOR SMARTPHONE
Document Type and Number:
WIPO Patent Application WO/2020/230379
Kind Code:
A1
Abstract:
Smartphones and the like use high speed digital signals and electromagnetic noise is emitted therein. If electromagnetic noise is emitted once to a power source line or a ground line of the smartphone or the like, then the electromagnetic noise stays inside the smartphone and does not go to the outside thereof. If the electromagnetic noise that was emitted to the power source line and the ground line were discharged to the outside, the original accurate digital signal could be attained. This electromagnetic noise absorber includes a power source line terminal and a ground line terminal which are connected to a power source line terminal and a ground line terminal of a smartphone or the like via a USB cable. The electromagnetic noise absorber receives electromagnetic noise from the power source line and the ground line of the smartphone or the like. Inside the electromagnetic noise absorber, the received electromagnetic noise is absorbed by a noise filter circuit and an electromagnetic noise-absorbing copper plate, and dissipates.
