Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a mobile phone capable of protecting its head from electromagnetic waves emitted from a transmitting / receiving antenna of the mobile phone.

[0002]

[Prior art and problems]

 The number of users of mobile phones is increasing every year as a convenient means of communication that can be taken anywhere, and the number of users of mobile phones is expanding to a wide range of age groups, from young to mature. There is.

However, on the other hand, the influence of electromagnetic waves emitted from office automation equipment including communication devices such as mobile phones, transformers, and high-voltage electric wires on the human body has become a social problem, and in some regions of other countries, high-voltage electric wires are used. There are some places that do not allow construction of schools and facilities for children to go within a certain distance from. This is because some children have been exposed to the electromagnetic waves emitted from the high-voltage power lines, and the health results are even worse than those of children who are not affected by the electromagnetic waves.

The fact that an electromagnetic wave is emitted from a mobile phone, particularly from a transmitting / receiving antenna, means that the electromagnetic wave is transmitted through the head during a call, which is repeated many times a day. If so, it cannot be said that there are no health problems. Furthermore, as mentioned above, since it is often used by young people who are easily affected by health problems, it is thought that the electromagnetic waves passing through the head may have some effect on the human body today. It is becoming a problem.

[0005]

【Purpose】

 The present invention has been made in view of the above problems, and an object of the present invention is to provide a mobile phone capable of reducing the head penetration amount and the intensity of electromagnetic waves emitted from a transmitting / receiving antenna of a mobile phone. To do.

[0006]

[Means to solve the problem]

 The gist of the present invention is that in a mobile phone in which an earpiece and a transmitter are arranged vertically, an external antenna connection part is provided below the transmitter part, and the connection part is arranged downward toward the connection part. The mobile phone is characterized by being provided with an antenna having a short and flexible structure.

More specifically, the mobile phone of the present invention has an earpiece and a transmitter arranged vertically, and an external antenna connection is provided below the main body transmitter. Is. In addition, the external antenna to be mounted is configured integrally with the connector plug part that connects to the external antenna connection part of the mobile phone, and its shape includes both bar shape and coil shape. It is desirable that the connecting portion is arranged downward, and the antenna portion has a short length and a flexible structure. When this external antenna is connected, the circuit of the built-in antenna above the handset is cut off.

The flexible structure of the antenna part includes an element antenna that uses a lead wire or the like to form a helical antenna part by winding it in a coil, or a shape memory alloy or the like to form the antenna part. Good. Alternatively, the end portion of the antenna portion on the connector plug portion side may be configured to be bendable. Then, the connector plug portion and the antenna portion may be covered with a soft material such as vinyl or urethane. Also, it is desirable that the length of the antenna be set to match the frequency of the telephone.

Further, a light emitting diode may be provided in the connector plug portion, the antenna portion, or both portions so that the light is turned on at the time of incoming call or use. In order to light the light emitting diode, if a light emitting diode or the like is used to form a lighting circuit and the light emitting diode is lighted by radio waves, there is no need to separately prepare a power source for lighting.

[0010]

[Action]

 Since the mobile phone of the present invention is configured as described above, when the external antenna is connected, the circuit of the built-in antenna above the handset is cut off, and the transmission and reception of radio waves during a call are connected to the external antenna connection part. Since it is performed with the attached antenna, even if the mobile phone is used in contact with the head, the transmission and reception of radio waves are performed under the user's chin, and the distance between the antenna and the head can be increased. This can reduce the amount of electromagnetic waves that pass through the head. This is because the strength of electromagnetic waves weakens in proportion to the square of the distance.

【Example】

 Referring to the drawings, the mobile phone of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the mobile phone of the present invention. Is a transmitter section, 3 is a receiver section, 4 is an existing built-in antenna, and 5 is an external antenna connection section for mounting an antenna 6 which is a part of the present invention. 6 is an antenna which is a part of the present invention, 7 is a connector plug portion of the antenna 6, and 8 is an antenna portion.

Further, the antenna 6 can be attached to and detached from the mobile phone 1, so that the antenna 6 does not disturb the storage. FIG. 2 is a diagram showing an antenna mounted on a mobile phone. In FIG. 2A, the antenna portion 8 is a flexible structure portion 81 over the entire length, and the antenna portion 8 can be freely bent. You can

Further, in FIG. 1B, the antenna section 9 is attached to the connector plug section 7 at the refraction fulcrum 91, and the antenna section 9 can be refracted by the refraction fulcrum 91. There is. FIG. 3 is a diagram showing an antenna provided with a light emitting diode, and a light emitting diode (LED) 10 is provided in the connector plug portion 7 and the antenna portion 8.

Further, it may be provided in either the connector plug portion 7 or the antenna portion 8. Furthermore, either the connector plug portion 7 or the antenna portion 9 of the antenna shown in FIG. 2B, or , May be provided in both parts. FIG. 4 is a view showing a usage state of the present invention, in which the antenna 6 for transmitting / receiving the mobile phone 1 can be separated from the head 11.

[0015]

【effect】

 As described above, when the external antenna is attached to the mobile phone of the present invention, the circuit of the built-in antenna is cut off, the external antenna circuit is closed, and the external antenna extends below the main body, that is, below the user's chin, Electromagnetic waves are exchanged at a point away from the user's head, so the electromagnetic waves that pass through the head during a call can be reduced, which may affect people who call many times a day and the health effects. Even young people who are easily affected can use mobile phones without worrying about the effects of electromagnetic waves.

Since the antenna is detachable and the antenna part has a flexible structure, it does not hinder the carrying of the mobile phone with the antenna attached.

Since the LED lights up during a call, the user can always be aware of the location of electromagnetic waves and use it, and at night, it has fashionability as an illumination.
