However, among the electronic devices used in the state of being closest to the human body, the electromagnetic interference preventing article is mounted on the front surface of a portable telephone which is considered to have a high risk of electromagnetic interference. No space. In other words, the commercially available positive ion neutralization type electromagnetic interference prevention products are generally disc-shaped with a diameter of 20 to 30 mm, but on the front of mobile phones designed to be small and lightweight,
There is absolutely no room to attach a device of this size.

FIG. 3 shows the state of the front of a general portable telephone. In the figure, 1 is a speaker unit, 2 is a display unit, 3 is an operation unit, and 4 is a microphone unit. These are arranged on the front face of the mobile phone without any gap as shown in the figure, and it is clear that there is no room for mounting the disk-shaped electromagnetic interference preventing article having a diameter of 20 to 30 mm.

[0005] Therefore, it is inevitably attached to the back side of the mobile phone to expect the effect of preventing interference. However, since the electromagnetic wave interference prevention article generates negative ions only in the vicinity thereof, the mobile phone can be brought closer. Positive ions around the ears and head of the human body cannot be efficiently neutralized with negative ions. An object of the present invention is to solve such a problem and to provide a product capable of efficiently neutralizing positive ions harmful to the human body with negative ions and preventing electromagnetic interference.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a substrate on which an ion generating layer using a radioactive natural mineral that generates negative ions is disposed on the upper surface is directly mounted on the upper surface of a speaker section of a portable telephone.

The ion generating layer is formed by coating a thin film surface with radioactive natural mineral powder mixed in a binder, which is bonded to the upper surface of a substrate made of an elastic material such as polyurethane. An adhesive is applied to the lower surface of the substrate, avoiding the vicinity of the center, so that it can be attached to the upper surface of the speaker section of the telephone.

Since the substrate is made of an elastic material, it can be attached to the shape of the upper surface of the speaker section of various types of portable telephones with adaptability.

Since an opening or a small hole penetrating the ion generating layer and the substrate is provided near the center, the sound can pass without attenuation.

The overall size and shape of the electromagnetic interference preventing device are configured so as to cover the upper surface of the speaker portion of the mobile phone without shielding the display portion of the mobile phone or protruding from the outer shape.

According to the electromagnetic wave interference prevention article of the present invention configured as described above, the sound emitted from the speaker reaches the human ear through the opening or the small hole without being attenuated. In addition, harmful positive ions generated by the electromagnetic waves are neutralized by negative ions coming out of the ion generating layer of the electromagnetic wave interference preventing article attached to the speaker unit upper surface. Therefore, harmful positive ions drifting around the ears and the head can be reduced, and the human body can be protected from electromagnetic interference.

Since the amount of ions generated from the electromagnetic wave interference preventing article is proportional to the surface area of the generating layer, small holes are more advantageous than openings when it is desired to generate as many ions as possible. However, depending on the shape of the top of the speaker,
Since the small holes may be closed at the time of sticking, in such a case, by providing a gap on the lower surface side of the substrate as in the second aspect of the present invention, the passage of sound is prevented. Can be unobstructed.

FIG. 3 shows the general state of the upper surface of a cellular phone. In FIG. 3, a speaker unit 1 is generally formed with a recess 1a, and a plurality of small holes 1b at the center of the recess 1b for allowing sound to pass therethrough.
Is provided, and the user talks with this part close to the ear.

FIG. 1 shows a first embodiment of the present invention. FIG.
FIG. 1A is a plan view, and FIG. 1B is a view showing a state in which a section taken along the line AA in FIG. 1A is attached to the speaker unit 1 of the mobile phone. The planar shape and the size of the electromagnetic interference prevention article of the present invention are the same as those of the speaker 1 of the mobile phone shown in FIG.
The shape and size are such that the recess 1a is sufficiently covered, does not protrude from the outer shape of the mobile phone, and does not block the display unit 2.

Reference numeral 10 denotes an ion generating layer, which is a thin film obtained by mixing radioactive natural mineral powder into a binder. Reference numeral 12 denotes a substrate, which is formed of, for example, an elastic material such as polyurethane, and the above-mentioned ion generating layer 10 is joined to the upper surface thereof. An adhesive is applied to the periphery of the lower surface of the substrate 12 avoiding the central portion to form an adhesive layer 13, on which a release paper 14 is adhered. An opening 11 penetrates both layers of the ion generating layer 10 and the substrate 12 up and down, and allows sound provided at the center of each layer to pass therethrough.

In order to attach such an electromagnetic interference preventing article according to the first embodiment of the present invention to a portable telephone, the release paper 14 is peeled off and attached to the upper surface of the portable telephone by an adhesive layer 13 so as to cover the recess 1a. The sound emitted from the speaker unit 1 reaches the human ear without attenuation through the small hole 1b and the opening 11. In addition, positive ions generated by the electromagnetic waves are neutralized by negative ions from the ion generating layer 10. Therefore, harmful positive ions around the ears and the head can be reduced, and the human body can be protected from electromagnetic interference.

FIG. 2 shows a second embodiment of the present invention. FIG.
FIG. 2A is a plan view, and FIG. 2B is a view showing a state in which a section taken along the line AA in FIG. 2A is attached to the speaker unit 1 of the mobile phone. Also in this embodiment, the planar shape and the size of the electromagnetic wave interference prevention article are the same as those of the speaker 1 of the mobile phone shown in FIG.
And the shape and size are smaller than the outer shape of the mobile phone and do not block the display unit 2.

The upper surface of the speaker section 1 of the mobile phone is not limited to the one having the recess 1a as shown in FIG. 3, but also the one having a flat upper surface and the one having a convex shape. If an electromagnetic interference preventing article having a small hole is attached to the upper surface of such a speaker section, a flat portion or a convex portion closes the small hole, and the sound may be significantly attenuated. It is sufficient to make the small holes larger. However, considering that the amount of generated ions is proportional to the surface area of the ion generating layer, it is not desirable to make the small holes larger.

Therefore, in the second embodiment of the present invention, a plurality of small holes 25 penetrating the ion generating layer 20 and the substrate 22 are formed, and a gap 26 is provided on the lower surface of the substrate 22. Reference numeral 23 denotes an adhesive layer, and reference numeral 24 denotes a release paper.
This is the same as the embodiment.

In this way, even if the upper surface of the speaker unit 1 of the portable telephone has no dent, that is, even if the upper surface is flat or convex, the loudspeaker unit 1 of the electromagnetic wave interference prevention article having the small hole is provided. The sound can be passed without attenuating without closing the small hole.

The void 26 may be formed by processing the lower surface of the substrate 22 as described above, or may be formed by increasing the thickness of the adhesive layer 23.

It reduces harmful positive ions around the ears and head of a person and protects the human body from electromagnetic interference. The effect is equal to or greater than that of the first embodiment.

[0025]

As described above, the electromagnetic wave interference prevention article of the present invention is provided with an opening or a small hole near the center to allow sound to pass therethrough, covers the speaker of the mobile phone, and protrudes from the outer shape or display of the mobile phone. Since the shape and the configuration can be applied to the upper surface of the speaker unit without using it, it is possible to efficiently prevent the electromagnetic interference caused by the mobile phone by neutralizing harmful positive ions with negative ions.
