DEVICE FOR DECREASING ELECTROMAGNETIC WAVE AND REDUCING STRESS USING LONGITUDINAL WAVE

摘要

The present invention provides a device for decreasing an electromagnetic wave and reducing a stress using a longitudinal wave. The device for decreasing an electromagnetic wave and reducing a stress comprises: a housing of a memory card form capable of being inserted into a card slot of an electronic device; an input/output interface formed on one surface of the housing, and connected to a card connector of the electronic device; a power interface part realized in a power supply terminal and a ground terminal among a plurality of contacts of the input/output interface, and receiving the power from the electronic device; and an electromagnetic wave decreasing circuit part provided in the housing, and including an electromagnetic wave decreasing circuit pattern which is connected to the power interface part and generates a longitudinal signal for decreasing the electromagnetic wave of the electronic device to transmit to the electronic device.;COPYRIGHT KIPO 2018
