[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a communication device according to the present invention will be described with reference to FIGS.
1 is a perspective view of a mobile phone as a communication device according to the present invention in an open state, FIG. 2 is a side view thereof, FIG. 3 is a plan view thereof, FIG. 4 is an enlarged cross-sectional view taken along the line AA of FIG. FIG. 5 is a perspective view of the mobile phone of FIG. 1 with the microphone case closed, and FIG. 6 is a side view of the mobile phone of FIG. 1 in a folded state.
[0011]
In FIG. 1, a mobile phone according to the present invention includes a display case 1, a main body case 2, and a microphone case 3. The display case 1 is made of, for example, a metal or a synthetic resin. A display unit 4 for displaying characters or images is disposed inside a central portion thereof, and a speaker unit 5 for outputting sound is disposed above the display unit 4. Have been. A hinge mechanism 6 is provided at one end of the display case 1, and an antenna unit 7 is mounted at the other end. One end of the main body case 2 is rotatably attached to the hinge mechanism 6. The main body case 2 has a main body 2a in which an electronic circuit unit 11 (see FIG. 4) for performing a call function, an e-mail, a homepage browsing, a game function, and the like are housed. The input key unit 2b includes a large number of key buttons 8 for performing the operation. The input key section 2b is composed of, for example, dial keys for inputting characters and numerals from 0 to 9 and a plurality of function keys. The entire input key portion 2b projects upward from the main body 2a as shown in FIGS. 1 and 2, and is slightly smaller than the outer shape of the main body 2a. The microphone case 3 is rotatably attached to the other end of the main body case 2 via a hinge mechanism 9. The microphone case 3 is formed in a frame shape with an opening at the center, and a microphone unit 10 for inputting sound is provided inside the lower end of the frame shape. As shown in FIGS. 3 and 4, the microphone unit 10 includes a microphone 10a and an external sound input opening 10b provided to face the microphone 10a. The microphone 10a is connected to a frame of the microphone case 3 by a wiring cable 10c. The wiring is electrically connected to a circuit board 12 on which an electronic circuit section 11 composed of an LSI or the like inside the main body case 2 is mounted through the shape passage.
[0012]
In the above configuration, when carrying the mobile phone, the microphone case 3 is closed by rotating the microphone case 3 inward with respect to the main body case 2 around the hinge mechanism 9 from the state shown in FIG. Then, as shown in FIG. 5, the outer shape of the input key portion 2b on the main body case 2 is inserted into the frame-shaped opening of the microphone case 3. Next, the display case 1 is rotated inward with respect to the main body case 2 about the hinge mechanism 6 and closed. Then, as shown in FIG. 6, the main body case 2, the microphone case 3, and the display case 1 are overlapped in this order, so that the entire device can be made compact and portable. In this state, the microphone section 10 of the microphone case 3 is covered with the main body case 2 and the speaker section 5 of the display case 1 is overlaid and hidden on the microphone case 3. For this reason, since the microphone unit 10 and the speaker unit 5 are not exposed to the outside when the mobile phone is carried, dust such as dust can be prevented from entering the microphone unit 7 and the speaker unit 5 and the display case 1 and the main body case can be prevented. 2. The inner surface of the microphone case 3 can be protected well.
[0013]
Next, a case where a call is made with this mobile phone will be described. The display case 1 is rotated about the hinge mechanism 6 with respect to the main body case 2 from the state shown in FIG. 6 and is opened to the state shown in FIG. Thus, the speaker unit 5 and the display unit 4 of the display case 1 and the input key unit 2b on the main body case 2 are exposed. Further, when the microphone case 3 is rotated around the hinge mechanism 9 with respect to the main body case 2 and opened, the microphone unit 10 is exposed as shown in FIGS. In this state, the main body case 2 is brought close to the side of the face, the speaker unit 5 of the display case 1 is brought close to the ear, and the microphone unit 10 of the microphone case 3 is brought close to the mouth.
[0014]
Further, when characters or the like are to be input for sending an e-mail or the like, the microphone case 3 is folded so as to overlap the main body case 2 as shown in FIG. The outer shape of the input key portion 2b is inserted so that the input key portion 2b of the main body case 2 is exposed from the frame-shaped opening of the microphone case 3. In this state, a key input operation of characters and the like can be performed, and the operability is good without the microphone case 3 being in the way. In addition, even when the microphone case 3 is folded so as to overlap the main body case 2, the height is the same as that of the main body case 2, and the thickness of the whole mobile phone when folded can be reduced.
[0015]
As described above, according to this mobile phone, when the display case 1 and the microphone case 3 are rotated and closed with respect to the main body case 2, the respective cases overlap, so that the mobile phone becomes compact when being carried. On the other hand, when the display case 1 and the microphone case 3 are rotated and opened, the distance between the speaker unit 5 and the microphone unit 10 can be ensured, so that an easy-to-use mobile phone device can be obtained. Further, since the input key portion 2b can be operated even when the microphone case 3 is overlaid on the main body case 2, the operability is good when characters or the like are input for sending an e-mail.
[0016]
Next, a second embodiment of the present invention will be described. FIG. 7 is a plan view of the main body case 22 and the microphone case 23 of the second embodiment, and FIG. 8 is a sectional view taken along the line BB of FIG. In the second embodiment, an opening is not formed in the microphone case 23 unlike the first embodiment, and the inside is a hollow audio passage as shown in FIG. A hole 23a for inputting an external sound is formed at the lower end. On the other hand, the microphone 10a is arranged in the hinge mechanism 29 at the lower end of the main body case 22, and a hole 29a is formed in the hinge mechanism 29 so as to face the hollow inside the microphone case 23. A hole 29b is formed above.
Therefore, in the second embodiment, when the microphone case 23 is opened, the sound input from the hole 23a is transmitted to the microphone 10a via the hollow passage of the microphone case 23 and the hole 29a of the hinge mechanism 29. Is transmitted. Further, when the microphone case 23 is closed, the voice input from the hole 29b of the hinge portion 29 is transmitted to the microphone 10a, and a call can be made even when the microphone case 23 is in the open state or the closed state. It is what becomes.
[0017]
In the above embodiment, a case where the present invention is applied to a mobile phone as a communication device has been described. However, the present invention is not limited to this. For example, a portable information device having a call function, for example, a PDA (personal digital assistant) with a call function, a handy device It can be widely applied to terminals, etc.
[0018]
【The invention's effect】
As described above, according to the present invention, when the display case and the microphone case are rotated and closed with respect to the main body case, the respective cases are overlapped with each other, so that the case is compact when being carried. When the microphone case is rotated and opened, the distance between the speaker and the microphone can be ensured, whereby a user-friendly communication device can be obtained. Further, since the input keys can be operated even when the microphone case is overlaid on the main body case, the operability is extremely good when inputting characters or the like.
