[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to an electromagnetic wave shielding member for mobile phones.

[0002]

[Problems to be solved by the device]

  With the spread of mobile phones in recent years, a micro that outputs from the inside when transmitting or transmitting The effect of waves on the human body has become a problem.

[0003]   This microwave output from the mobile phone is a mere 0.27W on average However, since it is located near the brain during use, we are particularly worried about the effects of electromagnetic waves. Not a few people

[0004]   In order to solve such a problem, it can be found in Utility Model Registration No. 3078573. , A resin fiber with a conductive film on the surface to cover the earpiece of a mobile phone For a mobile phone, which is configured by applying an adhesive to the peripheral edge of a conductor configured by Magnetic wave shielding members have been proposed.   According to this, electromagnetic waves can be absorbed to some extent, but in order to be more complete, electromagnetic waves are required. It is necessary to increase the wave absorption area.   The present invention has been made in view of such circumstances, and its purpose is to: It has a simple structure and is easy to put on, and while maintaining antibacterial properties, it may cause an obstacle to calls. First of all, because it effectively shields the electromagnetic waves from the mobile phone and allows you to use it with peace of mind. Another object of the present invention is to provide an electromagnetic wave shielding member for mobile phones.

[0005]

[Means for Solving the Problems]

  That is, the present invention solves the above problems by an electromagnetic wave shielding unit for a mobile phone. The material is either the mouthpiece or earpiece of the mobile phone, or the mouthpiece and And the earpiece part are coated with a conductive film made of antibacterial metal on the surface. A conductive material made of resin fibers is fixed to the frame, and a non-drying contact is made on the back surface of the frame. It can be used by forming an adhesive layer and attaching it to the mouthpiece part of the mobile phone or (and) the earpiece. It was made possible.

[0006]

【Example】

  Therefore, an embodiment of the present invention will be described below.   1 and 2 show an embodiment of the present invention, which is a mouthpiece of a mobile phone. The electromagnetic wave shielding member 10 attached to the portion A is a polymer film having relatively high rigidity. Punched into a semi-circular ring, and a metal film was formed on the surface side by vapor deposition A frame body 11, a mesh-shaped conductor 12 joined to the back surface of the frame body 11, and a conductor 1. 2 and a non-drying adhesive layer 13 formed in a region facing the frame body 11. ing.

[0007]   The conductor 12 is made of copper or copper nickel on the surface of a mesh fabric such as polyester. The alloy is electrolessly plated, and a special resin treatment that does not impair the antibacterial property is further applied. A guide called "Denji Mesh" (registered trademark of Nisshinbo Industries, Inc.) Because it is configured as an electric body, without blocking the voice from the mouthpiece of the mobile phone, It has a function of blocking about 90% of microwaves radiated from the inside.   Although the special resin treatment is applied in the above embodiment, it may be omitted if necessary. You can also

[0008]   As shown in FIG. 3, the electromagnetic wave shielding member 10 configured as described above is used as the mount 1 4 fixed by its own adhesive layer 13 and stored in a transparent bag if necessary Distributed as. Note that the mount 14 reduces the adhesive force of the adhesive layer 13 as much as possible. Therefore, it is desirable to form a polymer layer.

[0009]   To mount it on a mobile phone, first fold the mount 14 slightly Due to the rigidity of No. 1, a part of the electromagnetic wave shielding member 10 is separated from the mount 14, so Peel the peeled part of the item with your finger and peel it off the mount. Next, the conductor 12 is the mouthpiece of the telephone. After positioning so as to cover the portion A, the frame body 11 is pressed and firmly fixed.

[0010]   As a result, the voice is transmitted from the mouthpiece portion A through the texture of the conductor 12 without any trouble. Microwaves that reach the clophone and that are output from inside the phone body are conductors. Block 12 as much as possible to make the mobile phone ready for use.

[0011]   On the other hand, the conductor 12 is made of copper or a copper-nickel alloy and contains no copper. Therefore, a clean state is always maintained by the bactericidal power against the bacteria attached to the mouthpiece part A. Can be maintained for a long time.

[0012]   In the above-mentioned embodiment, the conductive layer is made of copper or copper-nickel alloy. However, even if it is made of silver or a silver alloy, it has an electromagnetic shielding effect and an antibacterial effect. You can

[0013]   FIG. 4 shows another embodiment of the present invention, in which the surface of the mount 25 is preferably While the central area is used as an advertisement copy or a handling explanation area, the advertisement copy And the electromagnetic waves for the earpiece, which will be described later, are determined by the orientation of the characters and images The shielding member 20 and the electromagnetic wave shielding member 10 for the mouthpiece described above are provided below. Lightly fixed by the adhesive strength of each adhesive layer 13, and accommodated in a transparent bag as needed. It is a thing.

[0014]   The electromagnetic wave shielding member 20 for the earpiece is the electromagnetic shielding member 1 for the mouthpiece described above. Basically, it has the same structure as that of 0. A frame body that is punched out in a circular ring shape and has a metal film formed by vapor deposition on the surface side 21 and the mesh-shaped conductor 22 joined to the back surface of the frame body 21 and the conductor 12. , A non-drying adhesive layer 23 (FIG. 6) formed in a region facing the frame 21. Has been.

[0015]   According to this embodiment, the mobile phone has an earpiece and a mouthpiece associated with the placement of The fixed electromagnetic wave shielding member 20 is used for the earpiece and is fixed to the lower part. It is possible to intuitively judge that the existing member is the electromagnetic wave shielding member 10 for the mouthpiece. Electromagnetic shielding member with a large size and high electromagnetic shielding effect for earpiece Prevent 20 from being accidentally stuck to the mouthpiece and stick it to the proper position as shown in Fig. 5. Can be attached.

[0016]   In addition, the member 20 for shielding the electromagnetic wave of the earpiece is rigid due to the increased size. As shown in FIG. 6, in order to assist the peeling from the mount 25, the short side The protective piece 24 is fixed to a part of the non-drying adhesive layer 23 on the side to reduce the adhesive force. It is desirable that they be easily peeled off.

[0017]

[Effect of device]

  As described above, according to the present invention, it is possible to connect to the mouthpiece or earpiece of a mobile phone. A microphone that can be leaked from the phone without causing any trouble in the call just by wearing it You can use the mobile phone with peace of mind by blocking the waves as much as possible. .   In addition, the antibacterial action of the conductor can always maintain a clean state.
