Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a device for shielding or removing harmful electromagnetic waves emitted from a mobile phone.

[0002]

[Problems to be solved by conventional techniques and devices]

 In recent years, the penetration rate of mobile phones in Japan and overseas has continued to increase, and the usage rate has become universal. However, electromagnetic waves emitted by home appliances are said to have a negative effect on the human body, and mobile phones are no exception. Long-term use can be harmful to humans if long-term exposure to electromagnetic waves has a negative effect on the human body. Outside of the country, there have been several reports of cell phone brain lesions, which have caused a number of lawsuits and social problems.

[0003] Manufacturers of mobile phones recommend that users extend their antennas when using mobile phones. However, there is no report or announcement in the medical community regarding the strength of electromagnetic waves emitted by mobile phones and their effects on the human body.

[0004] This is because the electromagnetic waves emitted from the mobile phone more or less affect the brain of the human body, and therefore, the usage manual describes the usage method in such a detailed manner.

In order to solve such a problem, in a conventional device, a conductive cloth having conductivity is attached to a mobile phone to provide an electromagnetic wave shielding effect.

However, the conductive cloth only shields the electromagnetic waves, and cannot discharge the electromagnetic waves to the ground. In addition, the conductive cloth cannot completely shield the electromagnetic waves 100%, and cannot prevent the emission of a small amount of the electromagnetic waves.

[0007] The conventional electromagnetic wave shielding device made of only a conductive cloth basically has an effect of reducing the effect of the electromagnetic wave on the head of the human body as a measure against the electromagnetic wave, but completely removes the effect. It can be said that it can be extremely difficult.

[0008] In view of the above situation, it is an object of the present invention to provide a compact and practical device for removing electromagnetic waves for mobile phones, which makes it possible to more completely remove harmful electromagnetic waves.

[0009]

[Means for Solving the Problems]

 A conductive front side layer 2 having an overall shape sufficient to partially cover the outside of the audio output unit 1A of the mobile phone 1 and capable of directly and indirectly contacting the mobile phone 1 includes a high magnetic conductive inner back layer 3. The main component is formed in a substantially plate-like (coin-shaped) body to provide the electromagnetic wave removing device of the present invention.

The inner layer 3 having high magnetic conductivity here is provided by a molding material containing, for example, a high proportion of tourmaline. More specifically, it is already possible to obtain a ceramic molded article containing tourmaline of 80 W% or more by a special technique.

As shown in the drawing, the high magnetic conductive inner back layer 3 forms the main body of the substantially plate-shaped molded product occupying from the inside to the back, but the layer formed from the surface to the peripheral side surface is not formed. The conductive surface layer 2 is formed mainly by plating, metal spraying, or application of a metal-containing chemical.

By attaching the conductive pressure-sensitive adhesive sheet 4 to the back surface of the above substantially plate-shaped body in advance, the sheet can be immediately attached to a predetermined location of the mobile phone except for the protective sheet 5. . The conductive adhesive sheet 4 may be set separately.

The degree of conductivity of the conductive pressure-sensitive adhesive sheet 4 does not need to be very high, since it is a level at which a weak current is transmitted from the conductive surface layer 2 to the mobile phone 1 without difficulty.

Therefore, the conductive pressure-sensitive adhesive sheet 4 itself does not block electromagnetic waves to a high degree, so that the shape may be a substantially plate shape, for example, a disk shape covering the entire back surface of a coin. As shown in the drawing, it may be a ring shape around only the periphery.

[0015]

[Action]

 Since the present invention has such a configuration, when this is attached near (backside) the audio output unit 1A, which is an electromagnetic wave generation source of the mobile phone 1, the electromagnetic wave emitted therefrom becomes an electric field like tourmaline. At the same time as being canceled out by the highly conductive inner backing layer 3 which acts to offset the change in vibration of the magnetic field, and the weak current generated by the conductive front side layer 2 via the conductive adhesive sheet 4, Alternatively, it is grounded in the air.

Therefore, since the movement of the electrons is always in a free state, the action of canceling or removing the electromagnetic waves can be exerted without any obstacle.

[0017]

[Embodiment of the invention]

 A ceramic containing 85 W% of tourmaline obtained by sintering by a special blending and firing technique is formed into a disc shape having a diameter of 18 mm and a thickness of 2 mm, and this is used as a highly magnetic inner backing layer 3. A plating layer of nickel or the like is formed on the side surface, and this is used as a conductive surface layer 2. A decorative layer 6 such as a pattern is further provided on the front surface, and a conductive adhesive sheet 4 with a protective sheet 5 having a diameter of 18 mm having a slight cushioning property is attached to the back surface to obtain a product. The present invention is not limited to such an example.

[0018]

[Effect of the invention]

 As described above, according to the present invention, there is an effect that a removing device for eliminating or removing harmful electromagnetic waves emitted from a mobile phone at a higher level, not simply insufficiently, can be provided in a very compact and easy-to-handle form.
