DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable wireless device using various communication means, and more particularly to a foldable portable wireless device.

[0002]

2. Description of the Related Art Recently, a PDC capable of high-speed data transmission.
(Personal Digital Cellular), CDMA (Code Divi
sion multiple access), GSM (global system for
Mobile Communication) and PHS (Personal Handy-ph)
Portable wireless devices using communication means such as one system) are widely used, and W is being developed as a next-generation technology.
Devices using communication means such as CDMA (Wide band CDMA) and CDMA2000 are being developed. As this type of portable wireless device, a foldable structure is known to enhance portability.

As shown in FIGS. 3A and 3B, a portable wireless device 1 having this folding structure includes a first housing 2 and a first housing 2.
A second housing 4 rotatably connected to the upper end of the first housing 2 by a hinge 3 is provided. Case 4
Are opened and closed with respect to the first housing 2.

[0004] The first housing 2 is provided with various input keys 5 as information input means and a microphone 6 as voice input means. Various information is input from the input keys 5 and voice input is performed by the microphone 6. Is performed.

[0005] The second housing 4 is provided with a display unit 7 as a display unit composed of a liquid crystal display exposed by opening and a speaker 8 as an audio output unit. Various character information and image information are displayed, and a sound such as a voice from a communication partner is output from the speaker 8. An antenna 9 made of a wire is provided at the upper end of the second housing 4 of the portable wireless device 1 so as to be able to be inserted and removed along the longitudinal direction of the second housing 4. When the portable wireless device 1 is used, the first housing 2
The second housing 4 is rotated and opened, and the antenna 9 is pulled out of the second housing 4 to talk with a communication partner.

[0006]

By the way, in the portable radio having the above structure, the antenna 9 is pulled out and the second
When the speaker 8 of the housing 4 is put on the ear and the microphone 6 of the first housing 2 is brought close to the mouth for talking, the antenna 9 comes close to the head of the user, and the communication sensitivity is reduced. There was a problem that would.

In particular, in recent years, this kind of portable radio has been
The transition from relatively large radios and mobile phones, mainly for business use, to small, thin, and lightweight mobile phones and personal handy phones has been rapidly changing, making it easier for users to use. Therefore, the decrease in sensitivity due to the proximity of the antenna 9 to the head of the user during a call is further increased.

[0008] Here, as shown in FIG.
From the upper end, which is the connection side with the second housing 4,
And a first housing 2 as shown in FIG.
There is a type in which the antenna 9 is inserted and removed along the second housing 2 from the back of the portable wireless device 1 and upward thereof. In these portable wireless devices 1, the antenna 9 is slightly moved away from the head of the user. However, it could not be sufficiently separated from the second housing 4 and the sensitivity was inevitably reduced.
Such a problem is more serious in the portable wireless device 1 in which the first housing 2 and the second housing 4 are hingedly connected to each other so as to be rotatable relative to each other. Had become. The present invention has been made in view of the above circumstances, and provides a portable wireless device capable of making a telephone call with good sensitivity by sufficiently separating an extracted antenna from a user's head or housing. It is intended to be.

[0009]

In order to achieve the above object, a second housing is rotatably connected to a first housing.
The second housing can be opened and closed with respect to the first housing.
In a state where the second housing is rotated and opened with respect to the housing, the audio output means provided in the second housing is directed to the ear,
A foldable portable wireless device used by bringing a voice input unit provided in a first housing close to a mouth, and a hinge portion on a connection side between the first housing and the second housing. The present invention provides a portable wireless device having a built-in antenna.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable wireless device according to an embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 11 denotes a portable wireless device. This portable wireless device includes a first housing 12,
A second housing 14 rotatably connected by a hinge 13 is provided at the upper end of the first housing 12, and the second housing 14 is turned at a connection position by the hinge 13. By moving, the second housing 14 is opened and closed with respect to the first housing 12.

That is, by rotating the second housing 14 from the state where the second housing 14 is closed (the state shown in FIG. 2), the second housing 14 is opened (the state shown in FIG. 1). Conversely, by turning the second housing 14 in the opposite direction from the state in which the second housing 14 is open, the second housing 14 is closed. It has become.

The second housing 14 has a display unit 2 on the front side, which is a side that is brought into contact with the first housing 12 when closed.
1 is provided. The display unit 21 is provided in the second housing 1
The display unit 21 includes a liquid crystal display provided at a position facing the display unit window 21a. The display unit 21 displays various contents.

The second housing 14 is provided with a speaker (sound output means) 23 at the upper end on the front side. The first housing 12 has a plurality of operation keys 24 for operation on the front side closed by the second housing 14.
Are provided, and various inputs can be made from these operation keys 24.

The first housing 12 is provided with a microphone (voice input means) 25 at the lower end on the front side, and further has an insertable / removable antenna 26 at the upper end on the back side. The communication of various communication data such as voice data, character data, and image data is performed through the antenna 26.

According to the portable radio device 11, voice input is performed by the microphone 25 while the second housing 14 is opened, and the voice of the other party is emitted from the speaker 23. Has become.

Next, by providing the built-in antenna 26 on the hinge 13 as shown in FIGS. 1 and 2, it is possible to eliminate a problem such as a decrease in sensitivity and to make a good call. Further, the hinge 13 needs a certain size in order to secure mechanical reliability, but has a space-saving effect because the antenna is built in using the space inside the hinge.

[0018]

As described above, according to the portable wireless device of the present invention, the second housing is rotatably connected to the first housing, and the first housing is connected to the first housing. Providing the built-in antenna in the hinge portion where the second housing can be opened and closed has the following effects. (1) A good call can be performed without a decrease in sensitivity or the like. (2) Since the antenna is built in by utilizing the space inside the hinge, there is a space saving effect.
