Description

  The present invention relates to a portable radio using communication means such as PDC (Personal Digital Cellular), CDMA (Code Division Multiple Access), GSM (Global System for Mobile Communication), and PHS (Personal Handy-phone System). .

  In recent years, portable radio using communication means such as PDC (Personal Digital Cellular), CDMA (Code Division Multiple Access), GSM (Global System for Mobile Communication), and PHS (Personal Handy-phone System) capable of high-speed data transmission. Devices using communication means such as WCDMA (Wide band CDMA) and CDMA2000, which are being developed as next-generation technologies, are being developed.

  In addition, this type of portable wireless device is also known that has a folding mechanism to improve portability.

  As shown in FIG. 8 as an example of a conventional foldable portable wireless device, the angle between the opposed surfaces 21a and 22a of the first casing 21 and the second casing 22 is determined via the hinge portion 23. It is variably connected between approximately 0 degrees and 180 degrees, and is provided with a key operation section 25 and a transmission section 24 on the surface 21a side of the first casing 21 facing the second casing 22, A display unit 26 and a receiver unit 27 are provided on the side of the second casing 22 facing the first casing 21 on the side of the first casing 21, and at the end of the first casing 21 or the second casing 22. One having an antenna (not shown) is known.

  However, the foldable portable radio device 20 shown in FIG. 8 has a problem that the telephone receiver 27 and the transmitter 24 are hidden in a folded state and cannot be used as it is. Therefore, when an incoming call is received in a folded state, it takes time and effort to perform an off-hook operation after opening the first casing 21 or the second casing 22 in order to make a call. There was also a risk that the phone would be disconnected if it took a long time to receive the call.

  In addition, when folded, the receiver 27 and the transmitter 24 come close to each other, which causes a problem of howling.

  Therefore, as a solution to such a problem, in Patent Document 1, as shown in FIG. 9, the second transmission is performed on the surface (outer surface) opposite to the facing surface 22 a of the second housing 22. There has been proposed a configuration in which a portion 28 and a second receiving portion 29 are provided, and an on-hook operation portion 30 and an off-hook operation portion 31 are provided on either side of the casing.

  According to this technique, when an incoming call is received at the time of folding, the second receiving unit 29 and the second receiving unit 29 and the second receiving unit 29 are not opened by pressing the off-hook operation unit 31 without opening the first housing 21 and the second housing 22. Therefore, there is an advantage that it is possible to shorten the time until the transition to the call and to save the trouble of operation.

  On the other hand, the portable wireless device 20 in which the angle between the opposing surfaces 21a and 22a is variably connected cannot see the display unit 26 in the folded state. A portable wireless device 40 as shown in FIGS. 10A and 10B has also been proposed because an operation such as opening the housing 22 is required and the operation is troublesome.

  The portable wireless device 40 includes a first housing 41 and a second housing 42 that are arranged to face each other and are rotatable about an axis perpendicular to the opposing surfaces. A key operation unit 45 and a microphone 44 as a transmitter are provided on the surface of the housing 41 opposite to the second housing 42, and the outer surface of the second housing 42 opposite to the first housing 41. On the side, a display unit 46 and one speaker 47 as a receiving unit have been proposed (see Patent Document 2).

According to the portable wireless device 40, the display unit 46 can be viewed regardless of when the first casing 41 and the second casing 42 are expanded or folded, so that the caller can be easily confirmed. There was an advantage of being able to.

  However, the portable radio device 20 shown in FIG. 9 cannot see the display unit 26 even if it receives an incoming call when folded, and therefore cannot confirm the caller, and therefore cannot deal with a nuisance call or the like. There was inconvenience.

  In addition, since the transmitters 24 and 28 and the receivers 27 and 29 must be provided on the front and back of the second casing 22, respectively, the number of parts increases, the structure of the wireless device becomes complicated, and the size is reduced. There has been a problem that the portable wireless device 20 that is required to be light in weight cannot sufficiently satisfy the requirement.

  On the other hand, the portable wireless device 40 shown in FIGS. 10 (a) and 10 (b) has the display unit 46 exposed even when folded, so that when a call is received, the caller can be confirmed immediately. As shown in FIG. 10 (b), the transmitter 44 is hidden behind the receiver 47 when folded, so that the telephone cannot be talked in the folded state. There is a problem that it takes time and effort to expand the body 41 and the second casing 42 and to perform an off-hook operation. In addition, since the receiver 47 and the transmitter 44 approach each other when folded, there is a problem that howling occurs.

  Therefore, in order to solve the above-described problems, the present invention provides a first casing and a second casing that are arranged to face each other and are rotatably connected around an axis perpendicular to the opposing faces, On the outer surface side of the second casing opposite to the first casing, and the microphone as the key operation section and the transmission section provided on the surface facing the second casing of the first casing Two speakers serving as a receiving unit disposed between the provided display unit and the display unit, and a detection unit that detects a deployed state and a folded state of the first casing and the second casing, And a control unit that controls to operate one of the two speakers based on the detection result of the detection unit and to disable the other speaker. To do.

  In addition, one of the two speakers is arranged on the connection side of both housings, and when the folded state of both housings is detected by the detection unit under the control of the control unit, the one speaker is operated. The other speaker is inactivated, and when the detection state of the two casings is detected by the detection unit, the one speaker is inactivated and the other speaker is operated. To do.

  Furthermore, one speaker of the two speakers is arranged on the connection side of both casings, and when the folded state of both casings is detected by the detection unit during a call under the control of the control unit, When one speaker is activated, the other speaker is deactivated, and when detecting the unfolded state of both housings during the call, the one speaker is deactivated and the other speaker is activated. It was made to let it be made to do.

  According to the portable wireless device of the present invention, a call can be made not only when the portable wireless device is expanded, but also when the portable wireless device is folded. Since information or the like can be displayed, the caller can be identified and a call can be immediately made according to the received information. Therefore, the caller is not kept waiting, and if it is a nuisance call, the call can be forcibly rejected. In addition, even when it is delayed to notice the incoming call, it is possible to improve the probability that the call can be made before the call hangs up, so that the caller does not feel uncomfortable and the portability as a portable radio is improved. Can fully demonstrate.

  Hereinafter, embodiments of the present invention will be described.

  FIG. 1 is a plan view showing a folded state of the portable wireless device of the present invention, FIG. 2 is a plan view showing a state in the middle of deployment of the portable wireless device of the present invention, and FIG. 3 is a deployed state of the portable wireless device of the present invention. It is a top view which shows the state of.

  A portable wireless device 10 according to the present invention includes a first housing 1 and a second housing 2 that are arranged to face each other, and is configured to be rotatable about an axis perpendicular to the opposing surfaces. .

Be able to. Note that the rotation mechanism in the portable wireless device 10 of the present invention is not limited to the one using the hinge shaft 3.

  The first casing 1 is provided with a key operation section 5 and one microphone 4 as a transmission section on the side facing the second casing 2, and the microphone 4 is an end opposite to the hinge shaft 3. It is arranged in the part.

  Further, on the outer surface side of the second casing 2 opposite to the first casing 1, a display unit 6 such as a liquid crystal display device and two speakers serving as a receiving unit disposed with the display unit 6 interposed therebetween. 7 and 8, one speaker 7 is disposed in the vicinity of the hinge shaft 3, and the other speaker 8 is disposed at the end opposite to the hinge shaft 3. An antenna 9 is housed in the first housing 1 so that it can be taken in and out, and can be taken in and out from the end surface of the first housing 1 on which the hinge shaft 3 is disposed.

  Next, as shown in the block diagram of the portable wireless device 10 of the present invention in FIG. 4, the second housing 2 has a transmitter 11 and a receiver 12 connected to the antenna 9, and a controller 13. The control unit 13 is connected to the microphone 4, the two speakers 7 and 8, the display unit 6, and the key operation unit 5. In addition, 15 is a storage unit connected to the control unit 13, 14 is a battery, 16 is a first detection unit, 17 is a second detection unit, and the first detection unit 16 and the second detection unit 17 are respectively An unfolded state of the second casing 2 relative to the first casing 1 is detected. That is, as shown in FIG. 5, two conductor patterns 16a and 17a are formed on the outer periphery of the hinge shaft 3, and the two conductive terminals 16b and 17b are connected to the two conductor patterns 16a by the rotation of the hinge shaft 3. , 17a is in contact / non-contact to detect the on / off state.

Specifically, as shown in Table 1, when the first detector 16 is on and the second detector 17 is off, the first housing 1 and the second housing 2 are completely When the first detection unit 16 is in the on state and the second detection unit 17 is in the on state, the second housing 2 becomes the first housing 1. When the first detector 16 is off and the second detector 17 is on, the second housing 2 is 180 degrees with respect to the first housing 1. When the first detection unit 16 is in an off state and the second detection unit 17 is in an off state in the rotated and unfolded state (FIG. 3), the second housing 2 is in a state other than the above (FIG. 2). is there.

  The relationship between the state of the first detection unit 16 and the second detection unit 17 and the developed state is not limited to the pattern shown in the specific example, and may be set as appropriate.

  The portable wireless device 10 of the present invention can make a call not only when the first casing 1 and the second casing 2 are unfolded but also when folded.

  The flow will be described with reference to the flowchart shown in FIG.

  First, when an incoming call is detected, the first detection unit 16 and the second detection unit 17 check the unfolded state of the first casing 1 and the second casing 2. For example, when an incoming call is detected, if the first detection unit 16 is in the off state and the second detection unit 17 is in the on state, the portable wireless device 10 is in the unfolded state (FIG. 3). Incoming information and the like are displayed on the display unit 6 so that the side is up, and the microphone 4 and the speaker 8 located farther from the microphone 4 (the end opposite to the hinge shaft 3) are operated, respectively, in the vicinity of the microphone 4 (hinge The speaker 7 in the vicinity of the axis 3 is inactivated. Then, a call can be performed by pressing an off-hook operation unit (not shown) and bringing the speaker 8 close to the ear.

  When the incoming call is detected, if the first detection unit 16 is in the on state and the second detection unit 17 is in the off state, the portable wireless device 10 is in the folded state (FIG. 1), so the speaker The incoming information and the like are switched and displayed on the display unit 6 so that the 7 side is on the upper side, and the microphone 4 and the speaker 7 located far from the microphone 4 (near the hinge shaft 3) are operated, The speaker 8 at the opposite end) is deactivated. Then, a call can be performed by pressing an off-hook operation unit (not shown) and bringing the speaker 7 close to the ear. At this time, the portable wireless device 10 is not deployed and does not have a length sufficient to place the microphone 4 in the vicinity of the mouth, but the transmission sound is sufficiently collected by increasing the sensitivity of the microphone 4. Can sound.

  Further, when an incoming call is detected, if the first detection unit 16 is on and the second detection unit 17 is on, or the first detection unit 16 is off and the second detection unit 17 is In the off state, since the second casing 2 is in the middle of deployment with respect to the first casing 1, it is only necessary to notify that there is an incoming call by an LED (not shown) or vibration. The display unit 6 has a background color, the microphone 4 and the two speakers 7 and 8 are inoperative, and when receiving an incoming call, the second casing 2 is completely folded or unfolded to make a call as described above. Is supposed to do.

  As described above, according to the portable wireless device 10 of the present invention, it is possible to make a call if there is an incoming call not only when the second casing 2 is unfolded but also when it is folded.

  Further, unlike the conventional portable radio device 20 shown in FIG. 9, there is no need to provide the microphones 24 and 28 and the speakers 27 and 29 on the front and back of the second housing 22, respectively, so that the number of parts can be reduced. In addition, the portable wireless device 10 can have a structure that contributes to a reduction in thickness and weight.

  Further, when a call is received, a ring tone can be generated from the two speakers 7 and 8 so that a ring tone having a stereo effect can be generated. Can be generated.

  Next, another example of the portable wireless device 10 of the present invention will be described with reference to FIGS.

  This portable wireless device 10 has a width W2 of the second casing 2 slightly larger than a width W1 of the first casing 1 and accommodates the antenna 9 in the second casing 2. The first housing 1 has the same structure as that shown in FIG. 1 except that the position at which the hinge shaft 3 is disposed is slightly shifted from the center of the lateral width.

  That is, when the antenna 9 is housed on the second housing 2 side, the antenna 9 is housed on the side of the second housing 2 facing the first housing 1 by reducing the thickness. The projecting portion 2b must be provided, and when the projecting portion 2b folds the second casing 2, it cannot interfere with the first casing 1 and cannot be completely folded. The lateral width W2 of the second casing 2 is configured to be slightly larger than the lateral width W1 of the first casing 1 (for example, the width that can accommodate the antenna 9), and the first casing 1 is hinged. A portable wireless device 10 that can be folded so that the first housing 1 does not protrude from the second housing 2 even when folded is obtained by slightly shifting the position at which the shaft 3 is arranged from the center of the lateral width. can do.
