Abstract

PROBLEM TO BE SOLVED: To improve speaking quality, especially, to improve voice quality at the time of transmission surrounded with noises. SOLUTION: This foldable telephone set, which can be folded into two by a hinge 6, is composed of a reception part housing section 10 housing a reception part 1, stretchable antenna 3 and display part 4 and a transmission part housing section 20 provided with a transmission part 2 and a dial operation part 5. Then, the reception part 1 has the projecting form having the almost same diameter as an earhole and the transmission part 2 incorporating a microphone has a recessed form so as to be fitted with the projecting section of the reception part 1 at the time of folding into two. Thus, not only the sharpness of speaking at the time of use is remarkably improved but also portability and strength at the time of carrying are considerably improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable telephone, and more particularly to a foldable telephone having a structure for increasing the clarity of a call.

[0002]

2. Description of the Related Art Conventionally, mobile phones having various shapes have been put to practical use or proposed in order to improve portability and call quality.

As a first conventional example, the Mova N series developed by NEC Corporation, in which the main body is folded in two (reference: NTT Mobile Communication Network Co., Ltd., 95-1 "Mova N User's Guide") There is a mobile phone.

As a second example, Japanese Unexamined Patent Publication No. 5-911.
The “foldable mobile phone” described in Japanese Patent No. 71, which has a substantially square bottom shape when folded, can be mentioned.

Further, as a third example, the actual Kaihei 3-90.
An example is a "handset" described in Japanese Patent No. 553, in which a convex portion is provided on the front surface of a handset case and a small handset unit is housed inside the convex portion.

Furthermore, as a fourth example, Japanese Unexamined Patent Publication No.
The "cordless telephone" described in Japanese Patent No. 209054 has a structure in which a convex portion provided on a telephone body and a concave portion provided on a handset are fitted to each other.

[0007]

In the Mover N series mobile phone of the first conventional example, the outer shape of the transmitter and the receiver is substantially flat, and there is a problem in that improvement in call quality cannot be expected. there were.

The foldable portable telephone of the second conventional example can be miniaturized, but the dial buttons are arranged vertically so that it is significantly less convenient than an ordinary telephone.
There was a problem that it was difficult to hold during a call.

Furthermore, the handset of the third conventional example is intended only for reception by the convex receiver, and there is a problem in that improvement in voice quality at the time of transmission under ambient noise cannot be expected.

Furthermore, the cordless telephone of the fourth conventional example is designed so that it can be hooked only when the concave and convex portions of the telephone body and the handset are aligned with each other.
There is a problem that improvement in call quality and robustness cannot be expected.

As described above, as a result of placing importance on portability, the conventional mobile phone has a problem that it is difficult to make a clear call for both transmission and reception in a place where ambient noise is large, such as a Shinkansen home. It was

The object of the present invention is to make the transmitter and the receiver fit into each other when folded in two, so that they are excellent in robustness and portability when folded and have a large ambient noise. An object of the present invention is to provide a foldable phone that enables clear calls even in places.

[0013]

According to the present invention, in a foldable telephone having a structure in which a receiving portion accommodating portion and a transmitting portion accommodating portion can be folded in two by a hinge, the receiving portion has a convex shape that can be inserted into an ear hole. A foldable telephone characterized by having a shape is obtained.

Further, there is obtained a foldable telephone characterized in that the transmitting portion containing the microphone has a concave shape.

Further, there is obtained a foldable telephone characterized in that, when folded in half, the concave portion of the transmitter portion can be fitted into the convex portion of the receiver portion.

[0016]

Next, the present invention will be described with reference to the drawings.

1 (a) and 1 (b) are a perspective view and a side view of an embodiment of a foldable telephone of the present invention, and FIG. 2 is a side view showing a folded state of the foldable telephone of this embodiment.

Referring to FIG. 1, the foldable telephone of this embodiment, which can be folded in two by a hinge 6, is provided with an earpiece 1,
It is composed of an earpiece accommodating portion 10 accommodating the telescopic antenna 3 and the display portion 4, and a transmitter portion accommodating portion 20 having a transmitter portion 2 and a dial operation portion 5.

The earpiece 1 has a convex shape having substantially the same diameter as the ear canal, and the microphone 2 with a built-in microphone has a concave shape that can be fitted into the convex shape of the earpiece 1 when folded in half. It has a shape.

Therefore, according to the present embodiment, when the telephone is used, the convex portion of the earpiece 1 comes into close contact with the ear hole, and the concave portion of the transmitter 2 enhances the sound collecting property.
It enables clear calls even in places with high ambient noise.

As described above, the difference between the present embodiment and the conventional example is the shapes of the receiving section 1 and the transmitting section 2. Therefore, the retractable antenna 3, the display section 4, the dial operation section 5 and the hinge 6 are the same. There is no big difference with the foldable phone.

Next, when carrying the foldable telephone of this embodiment, it is folded in two as shown in FIG. In this state, the convex portion of the receiving portion 1 fits with the concave portion of the transmitting portion 2, resulting in the smallest pocket size and significantly improving portability, and since it becomes a small box type, it is externally connected. The robustness is improved without damaging the transmitter / receiver or the like even under the impact of.

[0023]

As described above, according to the present invention, in a foldable telephone having a structure in which a receiving portion accommodating portion and a transmitting portion accommodating portion can be folded in two by a hinge, the receiving portion has a convex shape that can be inserted into an ear hole. And the microphone with a built-in microphone has a concave shape, and when folded in two, the concave part of the transmitter can be fitted into the convex part of the receiver. By this, not only the clarity of the call during use is significantly improved, but also the portability and robustness during carrying are significantly improved.
