Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
In current communication world, those controlling the communication
technology will become a winner of current information world. Thus,
communication devices have become necessary equipment. Since mobile
phones are more and more popular, almost everybody has one. However,
with the increment of communication traffic, electromagnetic radiation
is also filled in the air. But this is harmful to the human body.
Especially, the electromagnetic radiation from the mobile phone
of user himself (herself) because the radiation from user's mobile
phone is very near the body of user, especially the brain.
The current mobile phone system has been advanced to digital mobile
phones from early analog mobile phones, the frequency band ranges
from 800 MHz to 1000 MHz, recently, 1800 MHz frequency is also included.
Such high frequency electromagnetic radiation has a great transmission
property. When the mobile phone with a power of 0.5 watt is emitted,
it the mobile phone is near the neck portion of user, about 0.2
watt of power will penetrate through the head of the user and is
probably produced a bad effect.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to
provide an electromagnetic radiation protection device of a mobile
phone installed at one side of an antenna of a mobile phone, thereby
80% of electromagnetic radiation is absorbed, therefore the sub-effect
of the mobile phone is reduced greatly.
Another object of the present invention is to provide an electromagnetic
radiation protection device of a mobile phone installed at one side
of an antenna of a mobile phone. The device comprises an electromagnetic
wave absorbing piece, a dielectric plate, an electronic joint loop,
a negative electrode lead, etc. The electromagnetic wave absorbing
piece serves to absorb the electromagnetic wave toward the user's
head. Then the electromagnetic wave irradiates to the negative electrode
lead of a power source through the electronic joint loop and the
negative electrode lead.
A further object of the present invention is to provide an electromagnetic
radiation protection device of a mobile phone, which may be assembled
and used easily and is effective for isolating the electromagnetic
radiation of a mobile phone. The device is formed simply by a plurality
of metal pieces, plastic piece, and electronic circuit.
The various objects and advantages of the present invention will
be more readily understood from the following detailed description
when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIGS. 1, 2 and 3, the present invention is formed by
an electromagnetic wave absorbing piece 8, a dielectric plate 9,
an electronic joint loop 7, a negative electrode lead 6, etc. The
whole structure is further packaged with the signaling joint 1,
antenna fixture 2 (negative electrode), an insulating cover of the
signaling joint 3, an antenna joint 3, an antenna joint 4, a helical
antenna 5, etc of the antenna structure by plastic or rubber filling.
The electromagnetic wave absorbing piece 8 is installed at the side
near the helical antenna 5. The dielectric plate 9 serves to isolate
the electromagnetic wave absorbing piece 8 and the helical antenna
5. The lower end of the electromagnetic wave absorbing piece 8 is
connected to the input of the joint of the electronic joint loop
7. The output of the joint of the electronic joint loop 7 is connected
to the negative electrode lead 6. Another end of the negative electrode
lead 6 is connected to the negative electrode of the power source
of a mobile phone (such as the antenna fixing seat (2)). In practical
using, the original antenna structure is still a preferred embodiment
and is convenient in using. Although it is not embodied by the antenna,
the present invention can be used at the periphery of the antenna
for achieving the predict effect.
When the mobile phone is in using, the signal is carried by electromagnetic
wave and thus is sent by the antenna. This signal electromagnetic
wave is energetic and transmitted, that is so called electromagnetic
radiation. The emission of the electromagnetic radiation is omnidirectionary
around the cylinder of the antenna as a center. The strength of
the electromagnetic radiation is decreased with the square of the
distance to the antenna. When the mobile phone is near the ear,
it is apparently that the head of the user is within the range of
the electromagnetic radiation.
In the present invention, an electromagnetic wave absorbing piece
8 serves to absorb the electromagnetic wave radiating toward the
head. The material of the electromagnetic wave absorbing piece may
be a metal and located at the neck of the user in the same side
of the antenna 5.
The object of the dielectric plate 9 serves to avoid the directly
contact of the electromagnetic wave absorbing piece 8 and the helical
antenna 5. Thus, the electromagnetic wave absorbing piece 8 is assured
to perform the function of absorption. The material of the dielectric
plate 9 is plastic or other material. The width of the material
of the dielectric plate 9 will effect the absorption efficiency
of the electromagnetic wave absorbing piece 8. The wider the width,
the lower the absorption efficiency. While the absorbing radiation
energy will irradiate to the negative electrode of the power source
system through the negative electrode lead 6.
If the electromagnetic wave absorbed by the electromagnetic wave
absorbing piece 8 is not be cancelled, one half of the electromagnetic
wave will be reflected toward the direction of the antenna. While
another one half will transfer toward the head of the user. Thus,
the received electromagnetic wave is necessary to be cancelled.
The way for canceling the electromagnetic wave is that the electronic
joint loop 7 is connected to the negative electrode lead 6, then
the electromagnetic wave is converted as a current to flow to the
negative electrode of the power source so as to be cancelled. One
end of the negative electrode lead 6 is connected to the output
of the electronic joint loop 7, while another end thereof is connected
to the negative electrode of the power source system of a mobile
phone. The power source system may be circularly around the antenna
fixing seat 2. The electromagnetic wave absorbing piece absorbed
by the electromagnetic wave absorbing piece 8 is converted as current
by the negative electrode lead 6 and then flow to the negative electrode
of the power source for canceling, then the electromagnetic wave
toward user's head is canceled and therefore the harm to the user
is reduced to a minimum.
The electronic joint loop 7 is combined to an electronic (or mechanic)
joint through a signal driver. The signal driver receives the signal
from the signaling joint for switching over the electronic (or mechanic)
joint. Namely, in standby, the antenna severs to receive signal,
thus the signal is as small as not to drive a signal, then the electronic
(or mechanic) joint is opened. Now, the electromagnetic wave absorbing
piece 8 has no any effect. While as a ring is actuated or in speaking,
the antenna is in an emitting state, a larger signal will be sent
from the signaling joint 1 to the antenna for emitting. The signal
is large enough to drive the signal driver and force the electronic
(or mechanic) joint to close. Now, the electromagnetic wave absorbing
piece 8 will act. Namely, the radiating energy absorbed by the electromagnetic
wave absorbing piece 8 will be transferred to the negative electrode
of the power source through the joint so that the electromagnetic
radiation is reduced properly and the harm to human brain is decreased.
The advantages of the present invention will now described in the
following:
1. The electromagnetic radiation from the conventional antenna
to the head of the user will be decreased greatly.
2. In dial the handset and in standby condition, the receiving
signal in the head of user is approximately equal to that of the
conventional one.
3. The transceiver of the original user is unnecessary to add any
extra devices. It is only needed to update the original antenna
to the antenna of the present invention. Even the transceiver is
assembled with the antenna of the present invention.
Although the present invention has been described with reference
to the preferred embodiments, it will be understood that the invention
is not limited to the details described thereof. Various substitutions
and modifications have been suggested in the foregoing description,
and others will occur to those of ordinary skill in the art. Therefore,
all such substitutions and modifications are intended to be embraced
within the scope of the invention as defined in the appended claims.
