Description

  The present invention relates to a mobile terminal device such as a mobile phone or a PDA (Personal Digital Assistant), and more particularly to a mobile terminal device in which a first housing and a second housing are connected by a connection mechanism.

In general, a so-called foldable device in which a first housing and a second housing are connected by a hinge mechanism is the mainstream of mobile terminal devices typified by mobile phones. Recently, an apparatus has emerged that employs a multi-joint hinge mechanism so that the first and second casings can be rotated in any direction. According to this type of apparatus, the postures of the first and second housings can be set to desired states, thereby allowing the main display to be used as a camera finder, for example. (For example, refer to Patent Document 1).
JP 2002-141984

However, this type of conventional device uses an articulated hinge mechanism only for the purpose of setting the postures of the first and second housings to an arbitrary state, and is not used for any other purpose. The current situation is not.
The present invention has been made paying attention to the above circumstances, and the object of the present invention is to enable selection of different functions in accordance with a change in the posture of the second housing relative to the first housing, thereby enabling operation. An object of the present invention is to provide a portable terminal device with improved performance.

In order to achieve the above object, according to the present invention, the first housing and the second housing are connected by a connection mechanism, whereby the posture of the second housing with respect to the first housing is changed to the first direction. And a portable terminal device configured to be displaceable in a second direction different from the first direction and provided with a microphone and a speaker in at least one of the first and second housings , If an operation for displacing the attitude of the second casing relative to the first casing from the initial state is performed, whether the displacement direction of the attitude of the second casing is the first direction or not. It is determined whether the direction is 2. When it is determined that the displacement direction is the first direction, the first application is selected , and the microphone and the speaker are set to an operable state by the first application to input / output audio signals. the first process is executed, whereas when the displacement direction is determined to be the second direction selects a different second application from the first application, the microphone and the speaker by the second application according Is set to an inoperable state, and the second processing without audio signal input / output is executed.

Therefore, according to the present invention, when the attitude of the second casing with respect to the first casing is displaced, different applications are selected according to the displacement direction and different processing is executed. In other words, an operation for displacing the attitude of the second housing relative to the first housing can be used as a function selection operation for selecting a plurality of different processing functions. Compared to a conventional device that relies on key input operations, the number of key operations can be reduced to improve operability.
In addition, when the attitude of the second housing is displaced in the first direction, for example, processing related to a call or processing for audio recording / playback using a microphone and a speaker can be executed. On the other hand, if the attitude of the second casing is displaced in the second direction, it is possible to execute processing related to mail transmission / reception and access processing to a website without using a microphone and a speaker.

Further, when a display is provided in one of the first and second housings, if the displacement direction is determined to be the first direction, the first menu screen is selected and the display is displayed. It displayed on, whereas the displacement direction may be displayed on the display device to select a different second menu screen and the above-described first menu screen when it is determined that the second direction.

  According to such a configuration, a plurality of different menu screens can be selectively displayed on the display device in accordance with the displacement direction of the posture of the second housing relative to the first housing. For example, when the attitude of the second casing is displaced in the first direction, a menu screen for making a call is selected and displayed, while the attitude of the second casing is displaced in the second direction. If you do, select and display the menu screen for sending and receiving emails. As a result, the operation of the menu display button and the operation for selecting the call menu or the mail transmission / reception menu from the general menu become unnecessary, thereby reducing the number of key operations and improving the operability. It is also possible to dispense with the menu display button.

In short, according to the present invention, when the posture of the second housing relative to the first housing is displaced, different applications are selected according to the displacement direction, and the operation states of the microphone and the speaker are made different. By performing different processing depending on the variation direction of the housing, such as controlling or displaying a different menu screen, it varies depending on the change in the posture of the second housing relative to the first housing A function can be selected, thereby providing a portable terminal device with improved operability.

  FIG. 1 is a perspective view showing an external appearance of a mobile phone as an embodiment of a mobile terminal device according to the present invention. This mobile phone is a so-called foldable mobile communication terminal in which an upper housing 1 and a lower housing 2 are connected via an articulated hinge mechanism 6, and FIG. 1 is shown in a folded state (closed style), and FIG. 1B shows a state in which the housings 1 and 2 are opened (open style).

  The hinge mechanism 6 is attached to the lower casing 2 so as to be rotatable in the horizontal direction (in the direction of the arrow CD), and is rotatable in a vertical plane with respect to the rotary table 61 (indicated by the arrow). A support shaft 62 pivotally supported in the (A-B direction) and a bearing portion (not shown) for attaching the upper housing 1 to the support shaft 62 so as to be rotatable in the axial direction (arrow E direction). It consists of. By this hinge mechanism 6, the upper housing 2 can be opened and closed with respect to the lower housing 1 in the direction of arrows AB. At the same time, it can be rotated in the direction of arrow CD in the horizontal plane, and the upper casing 1 itself can be swung in the direction of arrow E.

  FIG. 2 shows a process of displacement of the posture of the upper housing 1 relative to the lower housing 2 and a state (style) after the displacement. The structure of the hinge mechanism 6 is merely an example, and various other structures can be conceived for displacing the posture of the upper housing 1 relative to the lower housing 2 in the above-described directions.

  The upper housing 1 is provided with a main display 3 on the front surface and a sub-display 4 on the back surface. Each of these displays 3 and 4 has a backlight disposed on the back side of a liquid crystal display (LCD) panel. On the other hand, an input device 5 is disposed in the lower housing 2. In addition to the dial keys, the input device 5 is provided with function keys such as a transmission key, an end key, a power key, a volume adjustment key, and a mode designation key.

  Further, a speaker 20 is disposed at a position near the upper end of the front panel of the upper casing 1, and a microphone 21 is disposed at a position near the lower end of the front panel of the lower casing 2. The speaker 20 and the microphone 21 are used when transmitting / receiving a call voice, recording a voice, reproducing an audio content, and the like.

  A displacement sensor 7 for detecting a change in the posture of the upper housing 1 relative to the lower housing 2 is disposed at a position close to the hinge mechanism 6 of the upper housing 1 and the lower housing 2. . The displacement sensor 7 includes a magnetic sensor, and includes a fixed magnet 70 attached to the upper housing 1 and three magnetic detection elements 71, 72, 73 disposed in the lower housing 2.

  First of all, the magnetic detection element 71 detects the separation of the fixed magnet 70 when the operation of opening the upper housing 1 in the direction of arrow A is performed from the initial state (closed style) shown in FIG. A detection signal is output. On the other hand, the magnetism detecting element 72 is the position of the fixed magnet 70 when the upper casing 1 is rotated counterclockwise (arrow C direction) in the horizontal plane from the initial state (closed style) shown in FIG. The passage is detected and a detection signal is output. On the other hand, the magnetic detection element 73 is a fixed magnet 70 when the upper casing 1 is rotated clockwise (in the direction of arrow D) in the horizontal plane from the initial state (closed style) shown in FIG. Is detected and a detection signal is output.

On the other hand, the circuit of the mobile phone is configured as follows. FIG. 3 is a block diagram showing the circuit configuration.
That is, a radio signal transmitted from a base station (not shown) is received by the antenna 11 and then input to the receiving circuit (RX) 13 via the antenna duplexer (DUP) 12. The receiving circuit 13 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 14 and converts the frequency into an intermediate frequency signal (down-conversion). Then, the down-converted intermediate frequency signal is orthogonally demodulated and a received baseband signal is output. The frequency of the local oscillation signal generated from the frequency synthesizer 14 is indicated by a control signal SYC output from the control unit 23.

  The received baseband signal is input to the CDMA signal processing unit 16. The CDMA signal processing unit 16 includes a RAKE receiver. In the RAKE receiver, the plurality of paths included in the received baseband signal are each subjected to despreading processing using spreading codes. Then, the signals of the respective paths subjected to the despreading process are synthesized after their phases are adjusted. Thus, received packet data in a predetermined transmission format is obtained. The received packet data is input to a compression / decompression processing unit (hereinafter referred to as a compander) 17.

  The compander 17 separates the received packet data output from the CDMA signal processing unit 16 for each medium by the demultiplexing unit. Then, the data for each separated medium is decrypted. For example, in the call mode, audio data such as call voice included in the received packet data is decoded by a speech codec. If the received packet data includes video data as in the television telephone mode, the video data is decoded by a video codec.

  The digital audio signal obtained by the decoding process is supplied to a PCM code processing unit (hereinafter referred to as a PCM codec) 18. The PCM codec 18 performs PCM decoding on the digital audio signal output from the compander 7 and outputs an analog audio signal. The analog audio signal is amplified by the receiving amplifier 19 and then output from the speaker 20.

  If the audio playback mode is set, the control unit 23 reads out the corresponding audio content from the storage unit 24, decodes the audio content, and then performs the speaker 20 via the PCM codec 18 and the reception amplifier 19. Amplify output from.

  The digital video signal decoded by the compander 17 is input to the control unit 23. The control unit 23 displays the digital video signal output from the compander 17 on the main display 3 via the video RAM. The control unit 23 displays not only the received video data but also video data captured by a camera (not shown) on the main display 3 via the video RAM.

  The compander 17 outputs the text data to the control unit 23 when the received packet data includes text data such as mail or application program. The control unit 23 stores text data such as the mail and application program in the storage unit 24. Then, the text data is read from the storage unit 24 in accordance with a display operation performed by the user on the input device 5, and the text data is displayed on the main display 3. The sub-display 4 displays information indicating the operation mode of the device, incoming call notification information, and information indicating the remaining amount or charge state of the battery 16.

  On the other hand, in the call mode, the voice signal of the speaker input to the microphone 21 is amplified to an appropriate level by the transmission amplifier 22 and then subjected to PCM encoding processing by the PCM codec 18 to become a digital audio signal, which is the compander. 17 is input. A video signal output from a camera (not shown) is digitized by the control unit 23 and input to the compander 17. Note that text data such as mail created in the control unit 23 is also input from the control unit 23 to the compander 17.

  The compander 17 detects the energy amount of the input voice from the digital audio signal output from the PCM codec 18, and determines the transmission data rate based on the detection result. Then, the digital audio signal is encoded into a signal having a format corresponding to the transmission data rate, thereby generating audio data. In addition, the digital video signal output from the control unit 23 is encoded to generate video data. Then, these audio data and video data are packetized by a demultiplexing unit according to a predetermined transmission format, and this transmission packet data is output to the CDMA signal processing unit 16. Even when text data such as mail is output from the control unit 23, the text data is multiplexed with the transmission packet data.

  The CDMA signal processing unit 16 performs spread spectrum processing on the transmission packet data output from the compander 17 using a spreading code assigned to the transmission channel. Then, the output signal is output to the transmission circuit (TX) 15. The transmission circuit 15 modulates the spectrum spread signal using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method. The transmission signal generated by this modulation is combined with a local oscillation signal generated from the frequency synthesizer 14 and frequency-converted into a radio signal. Then, the radio signal is amplified at a high frequency so that the transmission power level instructed by the control unit 23 is obtained. The amplified radio signal is supplied to the antenna 11 via the antenna duplexer 12, and transmitted from the antenna 11 to the base station.

When the recording mode is set, the microphone 21 and the transmission amplifier 22 are in an operating state. The audio signal input to the microphone 21 is encoded by the PCM codec 18 and the speech codec in the compander 17 and then input to the control unit 23, and stored in the storage unit 24 under the control of the control unit 23. The
Reference numeral 26 denotes a power supply circuit, which generates a predetermined operating power supply voltage Vcc based on the output of the battery 25 and supplies it to each circuit unit. The battery 25 is charged by a charging circuit (not shown).

  Incidentally, the control unit 23 includes, for example, a microcomputer as a main control unit, and newly has a displacement direction determination function 23a and an application selection function 23b as control functions according to the present invention. All of these functions are realized by causing the microcomputer to execute a program.

  The displacement direction determination function 23 a determines the change direction of the posture of the upper housing 1 relative to the lower housing 2 based on the detection signal output from the displacement sensor 7. For example, when a detection signal is output from the magnetic detection element 71, it is determined that the upper casing 1 is opened in the direction of arrow A in FIG. 1B, that is, in the state from S1 to S2 in FIG. When a detection signal is output from the magnetic detection element 72, it is determined that the upper casing 1 has been rotated counterclockwise (arrow C direction) within a horizontal plane. On the other hand, when a detection signal is output from the magnetic detection element 73, the upper housing 1 is rotated in the clockwise direction (arrow D direction) in the horizontal plane, that is, in the state of S1 to S6 shown in FIG. It is determined that

  The application selection function 23b selects and executes a corresponding application according to the change direction of the posture of the upper housing 1 determined by the displacement direction determination function 23a. For example, when the upper casing 1 is opened in the direction of the arrow A in FIG. 1B, the “total menu processing application” is selected and the “total menu” is displayed on the main display 3. On the other hand, when the upper casing 1 is rotated counterclockwise (in the direction of arrow C) in the horizontal plane, “email transmission / reception / web access processing application” is selected, and “email transmission / reception / web access menu” is selected. Is displayed on the main display 3. When the upper casing 1 is rotated clockwise (in the direction of arrow D) in the horizontal plane, “call / audio recording / playback application” is selected, and “call / audio recording / playback menu” is selected. Is displayed on the main display 3.

Next, an application selection execution operation by the apparatus configured as described above will be described. FIG. 3 is a flowchart showing the control procedure and control contents of the control unit 23.
In the initial state (the closed style shown in FIG. 1A or S1 in FIG. 2), the control unit 23 monitors the change in the posture of the upper housing 1 in step 4a. At this time, in the displacement sensor 7, the fixed magnet 70 of the upper housing 1 faces the magnetic detection element 71 of the lower housing 2 as shown in FIG. 5.

  In this state, it is assumed that the user performs an operation of opening the upper housing 1 in the direction of arrow A as shown in FIG. Then, when the fixed magnet 70 is separated from the magnetic detection element 71, the detected magnetic flux in the magnetic detection element 71 changes, and thereby a detection signal is output from the magnetic detection element 71. In step 4b, the control unit 23 determines that the attitude of the upper housing 1 has changed in the A direction based on the detection signal output from the magnetic detection element 71. Then, in accordance with this change direction, “application for comprehensive menu processing” is selected in step 4c, and “total menu” is displayed on the main display 3. This comprehensive menu includes all menus such as a user setting menu, a telephone directory menu, and an audio recording / playback menu, in addition to a call menu and a mail transmission / reception menu.

  In this state, when the user performs a key operation on the input device 5 to select and specify a desired menu, and further performs a key input operation necessary to execute the selected menu, the control unit 23 starts from step 4d. The process proceeds to step 4f, where processing corresponding to the selected menu is executed. Prior to the execution of the processing in step 4f, the speaker 20 and the microphone 21 are set to an operating state or a non-operating state in step 4e as necessary.

  On the other hand, it is assumed that the user rotates the upper casing 1 in the clockwise direction (arrow D direction) in the horizontal plane as shown in FIG. 7, for example, in the initial state. Then, a detection signal is output from the magnetic detection element 73 when the fixed magnet 70 passes through the magnetic detection element 73. In step 4b, the control unit 23 determines that the posture of the upper housing 1 is rotationally displaced in the D direction based on the detection signal output from the magnetic detection element 73. Then, “call / audio recording / playback processing application” is selected in step 4g according to the change direction of the posture, and “call / audio recording / playback menu” is displayed on the main display 3. The call / audio recording / playback menu includes a menu for making a call and a menu for recording / playing audio. That is, processing menus using the speaker 20 and the microphone 21 are collected.

  In this state, it is assumed that the user performs a key operation on the input device 5 to select and specify a desired menu, and further performs a key input operation necessary for executing the selected menu. Then, the control unit 23 proceeds from step 4h to step 4i, where the speaker 20 and its receiving amplifier 19 and the microphone 21 and its transmitting amplifier 22 are set to the operating state, respectively, and then the above selection is made at step 4j. The process corresponding to the menu that has been executed is executed. Thus, after that, the user can make a call or play audio contents.

  In the initial state, it is assumed that the user rotates the upper casing 1 counterclockwise (arrow C direction) in a horizontal plane as shown in FIG. 8, for example. Then, a detection signal is output from the magnetic detection element 72 when the fixed magnet 70 passes through the magnetic detection element 72. In step 4b, the control unit 23 determines that the attitude of the upper housing 1 is rotationally displaced in the C direction based on the detection signal output from the magnetic detection element 72. Then, according to the change direction of the posture, “email transmission / reception / web access processing application” is selected in step 4k, and “email transmission / reception / web access menu” is displayed on the main display 3. This mail transmission / reception / web access menu includes menus for transmitting / receiving mails and menus for web access.

  In this state, it is assumed that the user performs a key operation on the input device 5 to select and specify a desired menu, and further performs a key input operation necessary for executing the selected menu. Then, the control unit 23 shifts from step 4m to step 4n, where first, the speaker 20 and its receiving amplifier 19 and the microphone 21 and its transmitting amplifier 22 are set in a non-operating state. Thereafter, processing corresponding to the selected menu is executed in step 4o. Thus, after that, the user can send and receive e-mails, browse the website or download the contents.

  As described above, in this embodiment, the control unit 23 is provided with the displacement direction determination function 23a, and based on the detection signals selectively output from the magnetic detection elements 71, 72, 73 of the displacement sensor 7, A change direction of the posture of the upper housing 1 with respect to the body 2 is determined. Then, the application selection function 23b selects and executes the corresponding application according to the change direction of the posture of the upper housing 1 determined by the displacement direction determination function 23a.

  Therefore, when the posture of the upper housing 1 relative to the lower housing 2 is displaced, a plurality of different applications are selectively executed depending on the displacement direction. For example, when the upper housing 1 is opened in the direction of arrow A as described above, “application for general menu processing” is selected. On the other hand, when the upper casing 1 is rotated counterclockwise (arrow C direction) in the horizontal plane, “application for mail transmission / reception / web access processing” is selected, and conversely the upper casing 1 Is rotated in the clockwise direction (arrow D direction) in the horizontal plane, “call / audio recording / playback processing application” is selected. As a result, it is possible to use an operation for changing the posture of the upper housing 1 with respect to the lower housing 2 as a menu selection operation for selecting a plurality of different menus. Compared to the conventional device that relies on the key operation, the number of key operations can be reduced and the operability can be improved.

  Further, according to the displacement direction of the posture of the upper housing 1 with respect to the lower housing 2, it is controlled whether the speaker 20 and the microphone 21 are set to the operating state or the non-operating state. For this reason, the power consumption by the speaker 20 and the microphone 21 can be effectively managed to reduce power consumption.

  The present invention is not limited to the above embodiment. For example, in the embodiment, when the posture of the upper housing 1 is changed from the initial state (the housing is folded), a plurality of different applications are selected according to the change direction, and the menu screen is displayed. Said about the case. However, the present invention is not limited to this, and the above display is displayed when the posture of the upper housing 1 is changed to the arrow A direction, the C direction, or the D direction and then changed to a third direction different from the direction. A third menu screen or the like located in the lower layer of the menu screen may be displayed. In this way, it is possible to perform a menu selection operation over a plurality of layers by an operation of displacing the attitude of the housing, and thereby it becomes possible to eliminate the need for a key operation for menu selection.

  Further, by the displacement operation in the third direction, another application corresponding to the change direction may be selected and started. Further, the operation in the fourth direction and the fifth direction may be performed. Depending on the operation, menus in lower layers may be selected and displayed sequentially, or different applications may be selected and executed. In short, it is preferable to sequentially select and execute related applications each time the posture of the upper housing 1 changes.

  Furthermore, in the above-described embodiment, when the posture of the upper housing 1 is displaced in the direction of the arrow A and the direction of the arrow CD, the case where different applications are selected and executed according to the displacement direction has been described as an example. However, the present invention is not limited thereto, and when the upper housing 1 is rotated in the E direction, a different application may be selected and executed depending on the rotation direction.

  Further, when the attitude of the upper housing 1 is displaced in the direction of arrow C or D, the displacement angle is detected, and display data displayed on the main display 3 according to the detected angle of the upper housing 1 It is better to variably control the direction of If it does in this way, it will become possible to display on the main display 3 in the state where display data always erects. The displacement angle can be detected by detecting the rotation angle of the turntable 61 with an optical sensor or the like.

  In addition, the means for detecting the structure of the hinge mechanism and the change direction of the posture of the housing, the procedure and contents of the application selection execution control, the type and configuration of the portable terminal device, etc. also depart from the gist of the present invention. Various modifications can be made without departing from the scope.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
