BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic radiation protection device for a portable telephone, and more particularly to a technique for reducing the intensity of electromagnetic radiation to the head by using electromagnetic wave absorbing parts.

[0002]

2. Description of the Related Art As a detrimental effect on the information civilized society, the influence of energy-intensive electromagnetic waves on the human body is greater than before.
Many statistics and research reports warn of the harm of electromagnetic radiation to the human body. When a mobile phone with a firing energy rate of about 0.5 watts approaches the head, more than about 0.2 watts of energy pass through the head. Such figures are worried about the negative effects in the future. There are many types of protective equipment on the market, but their functions and effects have varied. The present invention theoretically cuts electromagnetic waves to the head by 80% or more. Such an effect can minimize the injury caused by the wireless communication device.

[0003]

SUMMARY OF THE INVENTION It is a primary object of the present invention to provide a device for reducing electromagnetic radiation to the head of a user, and a further object of the present invention is to provide a simple installation, convenient and convenient to use. It is an object of the present invention to provide a mobile phone electromagnetic radiation protection device having a remarkable effect.

[0004]

The present invention comprises an electromagnetic wave absorbing part, a mediating plate, an electronic contact circuit, a negative pole cord, etc. The electromagnetic wave absorbing part absorbs electromagnetic waves toward the user's head, After passing through the contact circuit, it is sent to the negative pole of the power supply with the negative pole cord and removed. As described above, the electromagnetic radiation intensity of the mobile phone in the direction of the user's head is reduced, and the injury to the head is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1, 2 and 3,
The present invention is composed of an electromagnetic wave absorbing part 8, a mediating plate 9, an electronic contact circuit 7, a negative pole cord 6, etc., and a transmission adapter 1 having an antenna structure as a whole, an antenna fixing base 2 (minus pole), a transmission adapter insulation 3, The antenna adapter 4, the spiral antenna 5, and the like are integrated by injecting plastic or rubber. Spiral antenna 5 with electromagnetic wave absorbing part 8
The spiral antenna 5 and the electromagnetic wave absorbing part 8 are separated from each other by an intermediate electric plate 9, and the bottom end of the electromagnetic wave absorbing part 8 is connected to the contact input terminal of the electronic contact circuit 7. And the negative output cord 6 are connected. The other end of the negative pole cord 6 is connected to the power supply negative pole of the mobile phone (for example, the antenna fixing base 2). Considering the actual use situation, the above combination is the most excellent method in the antenna structure style. However, when the antenna type is not used, the same effect may be achieved by attaching the device of the present invention to the outside. When a mobile phone is used, an electric signal is put on a radio wave and emitted from an antenna. These signal radio waves are electromagnetic waves having energy and transparency (so-called electromagnetic radiation), and the range of emission is around the antenna.
It fires evenly in a 0 degree circle. Its intensity is inversely proportional to the square of the distance from the antenna. Obviously, when the mobile phone is brought close to the ear, the human head is within the intense circular electromagnetic radiation range.

The principle of the present invention is to utilize the electromagnetic wave absorbing parts 8 to absorb electromagnetic waves heading toward the head. The material of the electromagnetic wave absorbing part 8 is a metal part, and the installation position is between the user's head and the spiral antenna 5. The purpose of the intermediary plate 9 is to prevent the electromagnetic wave absorbing part 8 and the spiral antenna 5 from directly contacting each other, thus exhibiting the absorbing function of the electromagnetic wave absorbing part 8. The material of the intermediary plate 9 is rubber or another material, and its material and thickness affect the absorption rate of the electromagnetic wave absorbing part 8. The greater the thickness, the lower the absorption, and all the absorbed radiant energy is transmitted from the negative pole cord 6 to the negative pole of the power supply system.
If the electromagnetic wave absorbed by the electromagnetic wave absorbing part 8 is not completely removed, half of the electromagnetic wave is reflected toward the antenna and the other half continues toward the user's head. Therefore, the received electromagnetic wave is removed, and a method of removing the electromagnetic wave is to connect the electronic contact circuit 7 to the negative pole cord 6 and to convert the electromagnetic wave into a current and send it to the negative pole of the power supply to remove the electromagnetic wave. One end of the negative pole cord 6 is connected to the output of the electronic contact circuit 7, and the other end is connected to the negative pole of the power supply system of the mobile phone. The negative pole of the power supply system is connected to the outer ring of the antenna fixing base 2 using a contact. The electromagnetic wave received by the electromagnetic wave absorbing part 8 has a negative pole code 6
After the electromagnetic wave is converted to electric current and sent to the negative pole of the power supply to remove the electromagnetic wave, the electromagnetic wave emitted from the antenna toward the head is reduced appropriately. And reduce injuries to the human body to a minimum.

The electronic contact circuit 7 is a combination of a signal driver and an electronic (or mechanical) contact. The signal driver opens and closes the electronic (or mechanical) contact according to the strength of the signal sent by the transmission adapter 1. That is, the standby antenna receives a signal, and when the signal is small, the signal driver is not moved, the electronic (or mechanical) contact is opened, and the electromagnetic wave absorbing part 8 does not operate at this time. However, when the bell is ringing, listening, or speaking, the antenna is in a firing state, and when a large signal is transmitted from the transmission adapter 1 to the antenna, the signal driver is driven according to the magnitude of the signal. Close the electronic (or mechanical) contacts. At this time, the electromagnetic wave absorbing part 8 works, and the radiant energy absorbed by the electromagnetic wave absorbing part 8 is transmitted from the contact to the negative pole of the power supply, and the electromagnetic radiation is appropriately reduced to reduce the injury to the head.

[0008]

The effects of the invention according to the above structure are as follows. 1. Effectively reduce electromagnetic radiation from the conventional antenna to the head. 2. It does not reduce the receiving sensitivity in the direction of the user's head in a standby and using situation. 3. According to the structure of the present invention, it is not necessary to attach any equipment and parts to the mobile phone originally used, and it is sufficient to replace the original antenna with the antenna of the present invention and mount it.
