Abstract

PROBLEM TO BE SOLVED: To keep an antenna away from the head of a user, when a portable phone is used and to reduce influences of an electromagnetic wave on the user by providing the antenna in the vicinity of a telephone microphone rather than a telephone receiver. SOLUTION: A portable phone is constituted of a telephone microphone 3, a telephone receiver 2, a display part 4, a dial 5 and an antenna 1 in a casing 6. When single equipment is used, the position of the ears is farther from the head than that of the mouth. Thus, the antenna 1 is installed in the vicinity of the telephone microphone 3 rather than the telephone receiver 2. More specifically, the antenna 1 is installed so that it is extended from the lower part of the telephone microphone 3 in the direction opposite to that for the conventional portable phone. Thus, the position of the antenna 1 can be set away from the head of the user in comparison with the conventional cellular phone, and effects of electromagnetic waves on the user is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a radio communication device, and more particularly to a radio communication device such as a portable telephone in which a handset and an antenna are integrated.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional portable telephone has an antenna 1, an earpiece 2, a mouthpiece 3, a display unit 4, and a dial 5 all attached to a housing 6 containing an electronic circuit. It consists of a single device. During use (during a call), the mobile phone is operated by operating a dial or the like as shown in FIG. 6 and then using the mouthpiece 3 and the earpiece 2 close to the ear. Therefore, in a conventional mobile phone, during a call, the antenna 1 is located near the head.

[0003]

In recent years, however, the influence of electromagnetic waves on living organisms has become a hot topic. Although the effects of strong electromagnetic waves, such as those applied to microwave ovens, have been recognized, the extent to which electromagnetic waves when transmitting and receiving wireless communication devices such as mobile phones actually affect the human body Has a theory that it has little effect, and a theory that it has a slight effect, but it is not clear. Although it is considered that there is no problem in a short-time wireless communication device for a short time, some users want to avoid it as much as possible.

[0004] In the case of a portable telephone, considering the electromagnetic waves received by the user, the transmitted electromagnetic waves are larger than the normally received electromagnetic waves. As shown in FIG.
The transmitted electromagnetic wave is radiated from the antenna 1. Also,
As described above, in the conventional mobile phone, the antenna 1 is near the head when used.

Accordingly, an object of the present invention is to provide a radio communication device in which a transmitting / receiving antenna is located at a position away from the head.

[0006]

In order to move the antenna far from the head, it is conceivable to separate the antenna and the handset from each other, but the portability as a single device is sacrificed. Becomes Considering the state of use as a single device,
The mouth is farther from the head than the ear, so
By arranging the antenna near the mouthpiece rather than the earpiece, the antenna can be used at a position farther than the head than in the related art.

That is, the present invention relates to a radio communication device having a mouthpiece, a earpiece and an antenna in the same housing, wherein the antenna is provided closer to the mouthpiece than the earpiece. is there.

[0008]

Embodiments of the present invention will be described below.

FIG. 1 is an external perspective view of a portable telephone according to an embodiment of the present invention. FIG. 2 is a diagram illustrating a usage example of the mobile phone according to the embodiment of the present invention.

As shown in FIG. 1, the mobile phone of the present invention is provided with a mouthpiece 3, an earpiece 2, a display unit 4, a dial 5, and an antenna 1 in a housing 6. The antenna 1 is attached near the mouthpiece 3. Specifically, the antenna 1 is attached so as to extend from a lower part of the mouthpiece 3 in a direction opposite to a conventional mobile phone.

Therefore, in the portable telephone of the present invention, as shown in FIG. 2, the position of the antenna 1 can be kept far from the head of the user during a call, as shown in FIG.

FIG. 3 is an external perspective view of a mobile phone according to another embodiment of the present invention. FIG. 4 is a diagram showing a usage example of a mobile phone according to another embodiment of the present invention.

As shown in FIG. 3, the mobile phone according to the present embodiment is mounted such that the antenna 1 extends in a direction perpendicular to the housing 6 from near the mouthpiece 3. Therefore, as shown in FIG. 4, the position of the antenna 1 can be avoided as far away from the user's head as in the above embodiment.

[0014]

The antenna of the portable telephone of the present invention is located farther from the user's head when used than the conventional portable telephone. Therefore, it is considered that the influence of the electromagnetic wave on the user when using the mobile phone is reduced.
