Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic wave suppressing member for a portable telephone which shields or suppresses harmful electromagnetic waves emitted from the portable telephone.

[0002]

2. Description of the Related Art Conventionally, as a member for shielding electromagnetic waves emitted from a portable telephone, for example, Japanese Patent Application Laid-Open No. H11-284389.
There has been one disclosed in Japanese Unexamined Patent Publication (Kokai) No. H10-26095. This electromagnetic wave shielding material is formed by forming a material formed by layering a silicon resin on an aluminum foil into a cross-girder shape. This electromagnetic wave shielding material is used by being fixed to the outer wall of a mobile phone.

[0003]

In the case of the above prior art, the manufacturing process is complicated, the cost is high, and the electromagnetic wave shielding effect is low. Further, only an electromagnetic wave suppressing effect was obtained, and there was no other function.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an electromagnetic wave suppressing member for a cellular phone which can effectively suppress electromagnetic waves harmful to the body with a simple structure. And

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided an electromagnetic wave suppression device for a mobile phone, which is provided with a conductive charcoal powder, a granular powder, and the like stored in a bag and attached to a strap of the mobile phone. It is a member. The mobile phone electromagnetic wave suppression member is formed to have a width of a mobile phone, and is used while being held together with the mobile phone when the mobile phone is used. The charcoal is made by burning wood at a high temperature and carbonizing it.
Bincho charcoal formed by baking twice at a temperature of about 1200 ° C. to about 1200 ° C., preferably about 1200 ° C. is preferred. Far infrared rays are radiated around this charcoal, and negative ions are generated. Furthermore, it has a dehumidifying and deodorizing function by the action of charcoal.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show an electromagnetic wave suppressing member 10 for a mobile phone according to this embodiment. The electromagnetic wave suppressing member 10 is made of Bincho charcoal formed by baking Ubamegashi twice at a high temperature of about 1200 ° C. The granulated charcoal 12 is obtained by crushing this Bincho charcoal to an appropriate particle size, for example, about 0.1 to 0.5 mm. The charcoal 12 is made of an inner bag 14 made of Japanese paper or non-woven fabric, which has air permeability and does not leak the charcoal 12.
And the inner bag 14 is housed in the outer bag 16. The outer bag 16 is in the form of a breathable bag on which a defined snack has been applied, and an attachment cord 18 is connected to one end edge.

[0007] The bags 14 and 16 are formed to be about the width of the mobile phone 20, and the length is about ３ to の of the length of the mobile phone 20. In addition, the charcoal 12 of Bincho charcoal emits about 2500 to 4000 negative ions per minute per 1 cm ³ . This is considered to be because far infrared rays emitted from the charcoal 12 act on water molecules in the air, and cause a large amount of water clusters having OH ⁻ negative ions to float in the surrounding air. Further, the charcoal 12 has a dehumidifying and deodorizing effect.

[0010] As shown in FIG. 1, the method of using the electromagnetic wave suppressing member 10 is such that the attaching cord 18 of the electromagnetic wave suppressing member 10 is connected to the attaching portion 24 of the strap 22 of the mobile phone 20. When the mobile phone 20 is used, the electromagnetic wave suppression member 10 and the mobile phone 20 are overlapped and held by hand, and the mobile phone 20 is put on the ear for use.

According to the electromagnetic wave suppressing member 10 of this embodiment, the electromagnetic wave radiated to the head of the user can be suppressed by simply attaching it to the strap of the mobile phone 20, and the electromagnetic wave necessary for a call can be transmitted to the human body. Radiates outward. Electromagnetic waves during a call strongly act on the human body, especially on the human brain, and there is a concern that harm is caused. By using the mobile phone 20 with the electromagnetic wave suppressing member 10, harmful electromagnetic waves can be easily shielded. Becomes possible. Moreover, the negative ions are constantly scattered from the charcoal 12, so that the effect of the negative ions, which is considered to be good for the body, can be always received. Furthermore, it has far-infrared radiation, deodorant and dehumidifying effects, and is also good for the user's body and the mobile phone 20.

[0010] The electromagnetic wave suppressing member of the present invention is not limited to the above embodiment, and the type of charcoal may be charcoal other than Bincho charcoal as long as the same effect can be obtained.
The shape of the charcoal may be granular or powdery, or may be divided into small pieces, and the size and shape can be appropriately set. Further, a hardened charcoal grain may be used. The method of mounting the electromagnetic wave suppression member of the present invention may be a method of attaching or locking to the surface of the mobile phone in addition to the method of mounting with the cord.

[0011]

The electromagnetic wave suppressing member for a portable telephone according to the present invention, which is attached to a strap or the like of a portable telephone, suppresses harmful electromagnetic waves from the portable telephone from being easily received by the human body, especially the head. . In addition, it can be easily attached to an existing mobile phone, and a large electromagnetic wave suppression effect can be obtained regardless of the type of the mobile phone. Furthermore, the effect of the negative ions radiated from the charcoal inside, the dehumidifying effect, the deodorizing effect, and the like can always be received, and a desirable effect can be provided only by having the human body.
