Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable terminal device such as a portable telephone.

[0002]

2. Description of the Related Art In recent years, various types of portable telephones including a PHS are commercially available. For example, JP-A-8-33
A foldable mobile phone as disclosed in Japanese Patent Application Laid-Open No. 1219 is common. FIG. 4 is a part of the drawing shown in this publication. In FIG. 4, reference numeral 60 denotes a mobile phone;
Is a speaker as a receiver, 64 is a microphone as a transmitter, 65 is a display unit, 66 is a numeric keypad for inputting a dial number or the like, 62 is a flipper, and 40 is a flipper 62.
This is a hinge mechanism for rotating. When the mobile phone 60 is not used or in standby, the numeric keypad 6
In order to prevent erroneous operation of the mobile phone 6, the flipper 62 is closed to cover the numeric keypad 66, and when the mobile phone 60 is used, the flipper 62 is opened to an angle of 145 degrees. In this example, the microphone 64 is the hinge mechanism 4
Although it is provided at 0, an example provided near the tip of the flipper 62 is also found on the market.

[0003]

However, in such a conventional flipper type portable telephone, even if the distance between the speaker and the microphone is not equal to the distance between the user's ear and the mouth, the speaker and the microphone cannot be used. The distance between the microphone and the speaker cannot be adjusted, so that when the speaker is put on the ear, the mouth is separated from the microphone, and there is a problem that sound is difficult to be transmitted clearly. The present invention has been made to solve such a problem, and the distance between the speaker and the microphone can be freely adjusted in accordance with the distance between the user's ear and the mouth. It is intended to provide an excellent portable terminal device that can be folded to a length.

[0004]

A portable terminal device according to the present invention comprises: a receiver for outputting a received voice signal and the like; and an upper portion having at least a display unit for displaying a telephone number, a communication message, an operation guide, and the like. An operating unit having numeric keys, function keys, etc., a lower part including at least a transmitter for converting voice into an electric signal, and a plurality of connecting elements and an intermediate part between the upper part and the lower part. And a connecting portion having a supporting shaft portion that engages with the connecting portion, and the connecting portion can be bent by the connecting element and the supporting shaft portion. With this configuration, the distance between the receiver and the transmitter can be adjusted according to the degree of curvature so as to match the distance between the user's ear and the mouth. , By combining the top and bottom,
The display unit and the operation unit can be protected from damage and erroneous operation.

[0005] In addition to the above, the connection element can be expanded and contracted by the connection element and the support shaft, so that the distance between the receiver and the transmitter can be reduced even if the connection is not bent. It can be adjusted to fit the distance between the ear and the mouth.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the appearance of the portable terminal device of the present invention. FIG. 1 (a) is a plan view, FIG. 1 (b) is a side view, and FIG.
(C) is a side view showing the folded state. In FIG. 1, reference numeral 1 denotes a portable terminal device, 2 denotes a display unit for displaying characters and symbols, 3 denotes an operation unit including numeric keys and function keys, 4
Is a speaker as a receiver, and 5 is a microphone as a transmitter. The portable terminal device 1 is connected to the display unit 2 and the speaker 4
An upper part 1a having an operation part 3 and a microphone 5 and a lower part 1b having a microphone 5 and a connecting part 10 having flexibility between them. Since the connecting portion 10 can be freely curved with the front surface of the mobile terminal device 1 inside, the space between the speaker 4 and the microphone 5 should be appropriately curved so as to match the space between the user's ear and mouth. Can be. Further, at the time of standby or when not in use, as shown in FIG. 1C, it is possible to bend and reduce the size to protect the operation unit 3 and the display unit 2.

FIG. 2 is an external view showing details of the connection unit 10 in the first embodiment of the portable terminal device of the present invention.
(A) shows the assembly of the connection element, and FIG.
FIG. 2B shows the structure of the connecting portion 10 and is shown in FIG.
(C) is a side view showing the curved state of the connection part 10. 11 is a connection element, one end of which is a concave portion, the other end is a convex portion, the concave portion has a hole 12a, and the convex portion has a hole 1a.
2b. The convex part of one connecting element 11 is inserted into the concave part of one connecting element 11, and the shaft 13 is passed through the holes 12a and 12b. At this time, a spring washer 14 is inserted into a gap between the concave portion and the convex portion to apply friction to the rotation of the connection element 11. Axis 1
The other end of 3 has a retaining means such as an E-ring 15.
Each time the shaft 13 is mounted, the connecting element 11 is connected to the outer ring 16.
Through. In order to hold the connection element 11 in contact with the bottom of the outer ring 16, a projection is provided on the inner wall of the outer ring 16 at a position in contact with the upper surface of the connection element 11. Outer ring 16 is shaft 1
The movement is restricted by the head of the third. Each connection element 11 is rotatable around an axis 13 as shown in FIG. 2 (b), and can be freely curved as shown in FIG. 2 (c). Since there is friction, the state can be maintained. Inside the outer ring 16, the connecting element 1
The space other than the space occupied by 1 is located on the back side of the portable terminal device 1 and serves as a passage for electric wires required for electrical connection between the upper portion 1a and the lower portion 1b.

FIG. 3 is an external view showing details of the connection unit 10 in the second embodiment of the portable terminal device of the present invention.
FIG. 3A shows the structure of the connection element, and FIG.
FIG. 3C shows the structure of the connecting portion 10, and FIG. 3C is a side view showing a curved state of the connecting portion 10. The outer arm fitting 21a and the inner arm fitting 21b are both formed by forming a plate material having high elasticity, such as metal or synthetic resin, into a U-shape. I have. Holes 23a are provided at both ends of the outer arm fitting 21a, and holes 23b are provided at both ends of the inner arm fitting 21b. When the angle between the outer arm fitting 21a and the inner arm fitting 21b changes, the plane of the hole 23a and the plane of the hole 23b are not strictly parallel, but the angle change is small.
It can be covered with a twist within the elastic limit. FIG.
As shown in (b), the connection portion 10 which can be expanded and contracted and which can be bent is obtained by rotatably connecting the hole 23a and the hole 23b of the adjacent connection element with the shaft fitting 24. Can be Although not shown, as exterior
The outer ring may be fastened together with the shaft fitting 22, or the outer ring may be covered with a thin rubber cylinder. The mobile terminal device 1 using the connection unit 10 assembled in this manner is:
By making the distance between the speaker 4 and the microphone 5 equal to the average distance between the human ear and the mouth in a straight, non-curved state, fluctuations due to individual differences can be adjusted by the expansion and contraction of the connection portion 10. In the case of extremely small intervals such as, for example, it can be adjusted to be smaller by bending.

[0010]

As described above, according to the present invention,
By making the connection part bendable, it is possible to adjust the distance between the speaker and the microphone to match the distance between the user's ear and the mouth, and in standby or when not in use, fold it down and make it smaller In addition, the display unit and the operation unit can be prevented from being damaged or erroneously operated.
