DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic wave absorbing device for a portable telephone for reducing the effect of electromagnetic waves generated from the portable telephone on the body.

[0002]

2. Description of the Related Art It is well known that an electromagnetic wave generated from a portable telephone may have an adverse effect on the body, but there is an electromagnetic wave suppressing device as means for suppressing the effect of the electromagnetic wave. Some of the electromagnetic wave suppression devices are configured to cover a mobile phone main body with an electromagnetic wave shielding member so as to shield electromagnetic waves generated from the mobile phone main body. The antenna is located near the most important brain of the body because the phone is close to the ear and talking with the other party, and the electromagnetic waves generated from this antenna are absorbed by the brain and eyes and adversely affect the body Becomes

In order to prevent adverse effects from the antenna, there is an electromagnetic wave suppression device in which an electromagnetic wave is prevented from leaking outside by covering the antenna portion with a shielding member. No attempt was made to prevent the adverse effects.

[0004]

The conventional electromagnetic wave suppression device shields the electromagnetic waves, and in order to ensure the shielding, the antenna portion and the telephone body must be entirely covered with a shielding member. Costly. In addition, mobile phones have been devised so that when the base station is close, the transmission power is reduced and the current consumption is reduced.However, if the antenna part is shielded, the radio wave from the base station weakens, and as a result, it becomes more than necessary. There is a problem that the transmission power is generated, the current consumption is extremely increased, and the operation time of the mobile phone is shortened.

[0005] The present invention has been made in view of the above-mentioned problems, and the electromagnetic wave, which is absorbed in the head and is said to have an adverse effect on the brain and eyes, is concentrated and absorbed in the hand holding the mobile phone, thereby reducing the cost. It is an object of the present invention to provide an electromagnetic wave absorbing device for a mobile phone that reduces the effect of electromagnetic waves on the brain and eyeballs without weakening radio waves from a base station.

[0006]

In order to achieve the above object, the invention according to claim 1 is an electromagnetic wave absorbing device for a mobile phone mounted on an antenna of the mobile phone, wherein the hand holding the antenna and the mobile phone is provided. And an absorbing member for absorbing electromagnetic waves generated by the antenna from the hand to the arm side.

According to a second aspect of the present invention, the absorbing member is formed of a conductive material that easily absorbs high frequencies.

According to a third aspect of the present invention, the absorbing member is formed in a cap shape for covering the antenna.

According to a fourth aspect of the present invention, the absorbing member is formed in an annular shape mounted on the outer periphery of the antenna.

According to a fifth aspect of the present invention, the absorbing member is formed of a conductive seal that can be adhered to the antenna and the portable telephone body.

According to a sixth aspect of the present invention, the absorbing member is provided so as to extend from the antenna to the portable telephone body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 shows an embodiment of an electromagnetic wave absorbing device for a portable telephone according to the present invention. The absorbing member 1 is formed in a cap shape and is covered by an antenna 12 of the portable telephone 11. This absorbing member 1 is formed by forming a conductive material into a shape attachable to the head of the antenna 12.

By attaching the cap-shaped absorbing member 1 to the antenna 12, when the owner of the portable telephone 11 talks with the other party, the electromagnetic wave is transmitted from the finger by touching the absorbing member 1 with the finger. Since it is absorbed by the torso along the arm, it can be prevented from being absorbed by the most important brain and eyeballs in the body.

FIG. 2 shows a second example of the electromagnetic wave absorbing device for a portable telephone.
In this embodiment, the absorbing member 2 is formed in an annular shape that is detachably attached to the outer periphery of the antenna 12. By attaching the annular absorbing member 2 to the antenna 12, the mobile phone 11 can be used. When the owner of the phone talks with the other party on the phone, the user touches the absorbing member 2 with his / her finger, so that the electromagnetic wave is absorbed from the finger to the arm and is absorbed by the torso, so it is absorbed by important brains and eyes in the body Can be prevented.

FIG. 3 shows a third embodiment of the electromagnetic wave absorbing device for a portable telephone.
In this embodiment, the absorbing member 3 is made of a conductive material and the antenna 12
Is formed in a predetermined shape so that it can be attached to the side of the antenna 3. By sticking this seal on the side surface of the antenna 3, when the owner of the mobile phone 11 talks with the other party over the telephone, the absorbing member is used. By touching the finger with 3, the electromagnetic wave is transmitted from the finger to the arm and is absorbed by the torso, so that it is possible to prevent the electromagnetic wave from being absorbed by important brains and eyes inside the body.

FIG. 4 shows a fourth embodiment of the electromagnetic wave absorbing device for a portable telephone.
In this embodiment, the absorbing member 4 is mounted on the antenna 12 as shown in the first and second embodiments, and the absorbing member 4a is formed integrally with the absorbing member 4a and mounted on the main body of the mobile phone 11. And a main body 4b. Therefore, if the absorbing member 4 of the present embodiment is mounted on the mobile phone 11, the owner only holds the mobile phone 11 in his hand,
A part of the hand comes into contact with the absorbing member 4, and the electromagnetic wave generated from the antenna 12 is absorbed from the hand to the body through the arm.

FIG. 5 shows a fifth embodiment of the electromagnetic wave absorbing device for a portable telephone.
In this embodiment, the absorbing member 3 is formed such that the absorbing member 5 is attached to only the antenna 12 of the third embodiment and extends to the back side of the main body of the mobile phone 2. . As a result, the owner only holds the mobile phone 11 during a call, so that a part of the hand comes into contact with the absorbing member 4, and the electromagnetic wave from the antenna 12 can be absorbed from the hand toward the body. Further, since the absorbing member 5 is a seal, it is inexpensive and convenient to handle, and does not disturb the mobile phone 11 even when it is attached to the mobile phone 11.

The absorbing member is preferably made of a conductive material that easily absorbs high frequency, but need not be a conductive material.

[0020]

As described above, the electromagnetic wave absorbing device for a portable telephone according to the present invention is provided for absorbing electromagnetic waves generated by the antenna between the antenna and the hand holding the portable telephone body from the hand to the arm side. Since the absorbing member is provided, it can be manufactured at low cost, and can also reduce the influence of the electromagnetic wave on the brain and eyeballs by absorbing the electromagnetic wave from the hand to the body while talking on the mobile phone.

According to the second aspect, since the absorbing member is formed of a conductive material that easily absorbs high frequency, the absorbing effect can be further enhanced.

According to the sixth aspect, the absorbing member is provided extending from the antenna to the main body of the portable telephone, so that the electromagnetic wave can be absorbed from the hand to the body only by grasping the portable telephone with the hand.
