Abstract

The present invention relates to a method for remarkably reducing damage of electromagnetic waves from a mobile communication device to the human body. According to the present invention, conductive metal foil paper or silver paper (aluminum foil) is added to the overall inner surface of front and rear sides of a folder-type case of a mobile communication device. When the mobile communication device is used while the folder is closed and the device is in contact with the ear and face, or when the mobile communication device is stored in a trouser pocket and the like while closing the human body, a large quantity of electromagnetic waves penetrated from a mobile communication device to the human body is conveniently and more completely shielded.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electromagnetic wave shielding case for a portable communication device,

The present invention relates to a method for blocking a large amount of electromagnetic waves generated in a portable communication device, and more particularly, to a foldable portable communication device of a smart phone, The present invention relates to a method of positively preventing electromagnetic waves generated in a portable communication device from being transmitted to a human body when receiving a telephone call or in a pocket.

Electromagnetic waves are electric magnetic waves, which are reduced by electromagnetic waves. Because the electric field and the magnetic field repeatedly spread like waves, they are called electromagnetic waves. Recently, the object of controversial electromagnetic hazards is 'Extremely Low Frequency' (ELF) generated in home appliances or transmission and distribution lines, and 'Radio Frequency' (RF) in radio frequency of mobile communication terminal and base station facilities. The United Nations International Agency for Research on Cancer (IARC) classified electromagnetic waves as grade 2 carcinogens in 1999 as 'potential carcinogens'

In particular, mobile communication devices are in contact with their ears and face most of the time, and they are in direct contact with the face. As a result, they are suspected of causing the rise of body temperature, brain tumor and cancer due to electromagnetic waves. In addition, it seems to be the cause of the sperm loss when storing mobile communication devices in the pants pocket.

One way to block these electromagnetic waves is to create a magnetic field membrane or wrap it in a conductor, and the simple method is to wrap it in a conductor. As a proof that conductors block the magnetic field, if you put food wrapped in a silver foil into a microwave oven in your daily life, you can see that the spark does not propagate inside the microwave. The electromagnetic wave shielding products of conventional portable communication devices are capable of blocking the receiving port of the portable communication device by a sticker method, and besides, the electromagnetic waves generated from other parts of the front and rear of the mobile phone can not be blocked positively. In the case of Korean Registered Patent No. 10-0616004 (Registered on September 13, 2005), a sticker type is attached to a receiving portion of a portable communication device. In the case of Registered Patent No. 10-1213380 (registered on Dec. 12, 2012) Sticker type. In this case, it is possible to apply regardless of the case type, but it can not actively shield most electromagnetic waves generated from the front and rear portions of the portable communication device.

Most recently used smart phones cover the front LCD screen and cover the front LCD screen to prevent unwanted touches. Most of the time, when the phone is in use, it covers the cover and makes contact with the ear and face. Because it can not block the electromagnetic wave, it is permeable to the head and face.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and it is an object of the present invention to minimize electromagnetic waves transmitted to a body when a portable communication device with a cover is directly put on the ear and face,

In order to achieve the above object, an electromagnetic wave shielding case of a portable communication device according to an embodiment of the present invention is characterized in that a portion directly closed with a portable communication device in front of a case of a portable communication device, The outer surface is covered with a conductive metal foil (silver foil), and then the outer surface is formed in various ways as it is now.

Preferably, the top, bottom, left and right sides of the portable communication device, in particular, the antenna portion are not covered with a metal foil for smooth communication, which is a unique function of the communication device.

The present invention relates to a portable communication device having a cover which is widely used in recent years, and more conveniently and safely shields electromagnetic waves from the front and back at a low cost, so that when the portable communication device is put on the ear and the face, By reducing the amount of electromagnetic waves to be transmitted, it can greatly help health promotion.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an electromagnetic wave shield case of a portable communication device according to the present invention will be described with reference to the accompanying drawings.

1 is a detailed perspective view of a method of attaching an electromagnetic wave shielding metal foil (silver foil) according to the present invention to a conventional foldable portable communication device case.

The front electromagnetic shielding metal foil 102 is entirely interposed between the covering layer 100 of the case and the case covering inner layer 104 so that electromagnetic waves generated in the front portion of the portable communication device can be cut off. In order to effectively transmit the reception voice of the portable communication device receiving unit 109 to the user, the front face of the conventional folding case has a hole 108 in the receiving case and an opening 110 in the receiving case, The front electromagnetic shielding metal foil is clogged without a hole for the receiving port. The metal foil is thin so that the sound waves pass efficiently, so there is no problem in performance. The front and rear ears shielding protective films 101 and 103 are attached back and forth in order to protect the front electromagnetic shielding metal foil 102 by the receiving groove inner case groove 108 and the receiving hole case outer groove 110.

The rear electromagnetic shielding metal foil 106 is additionally provided between the case bottom layer 107 and the case bottom outer layer 105 so that the electromagnetic waves generated from the back surface of the portable communication device can be cut off. The flashing recess 111, the camera recess 112, and the speaker recess 113 are formed in the rear electromagnetic shielding metal foil 106 so that the flash, camera, and speaker, which are additional functions of the portable communication device, can operate normally.
