ELECTROMAGNETIC SHIELDING DEVICE AND ELECTRONIC APPARATUS

摘要

An electromagnetic shielding device for shielding electromagnetic energy generated by an electronic apparatus. The electromagnetic shielding device includes a base board and a number of protrusions formed on the base board. The length of each protrusion along a direction perpendicular to the base board is adjustable. The amount of electromagnetic energy can be absorbed by the electromagnetic shielding device is adjusted according to the length of the protrusion.
