In addition, the display screen 4 on which the display associated with the execution of the inactive application 24 is referred to as “inactive screen 4”.

  In the present embodiment, a thin line 300 is displayed on the edge of the active screen 4. The thin line 300 is displayed in blue, for example. Thus, the user can easily specify which of the two display screens 4 the sound currently heard from the electronic device 100 corresponds to. In the example of FIG. 7, the moving image playback application with sound is the active application 24, and is displayed on the right end (right end for the user) of the second display screen 4b on which the display accompanying the execution of the sound moving image playback application is performed. A thin line 300 is displayed. Hereinafter, the thin line 300 is referred to as an “active screen specifying line 300”.

  Further, in the present embodiment, an operation provided in the casing (first casing 1 or second casing 2) provided with the active screen 4 out of the first operating section 10 and the second operating section 11. A plurality of operation keys included in the unit are lit. In each of the first operation unit 10 and the second operation unit 11, a plurality of operation keys provided in the operation unit can be turned on by a backlight. This backlight is controlled by the control unit 20. Thus, the user can easily specify which of the two display screens 4 the sound currently heard from the electronic device 100 corresponds to. In the example of FIG. 7, the home key 11a, the menu key 11b, and the back key 11c included in the second operation unit 11 provided in the second casing 2 provided with the second display screen 4b that is the active screen 4 are lit. doing.

  In the electronic apparatus 100 according to the present embodiment, when the display / sound output application 24 is executed, the user can determine which display screen 4 is to display the display / sound output application 24 using the key operation unit, the display screen 4, or the like. It can be selected by operating. That is, the user can select the display screen 4 to be used in the execution of the display / sound output application 24 by operating the key operation unit, the display screen 4 or the like. In electronic device 100 according to the present embodiment, when a plurality of display / sound output applications 24 are executed, one of first display screen 4a and second display screen 4b, for example, the second display screen is displayed. 4b becomes the active screen 4 first. Therefore, when a plurality of display / sound output applications 24 are executed, sounds related to the display on the second display screen 4 b are first output from the second sound output unit 9.

  In addition, when the display accompanying the execution of the inactive application 24 is a reproduction display of a moving image, the moving image may be reproduced on the display screen 4 that performs the display accompanying the execution of the inactive application 24. The playback of the moving image may be stopped. When the reproduction of the moving image related to the inactive application 24 is stopped, when the inactive application 24 is changed to the active application 24, the reproduction of the moving image is resumed automatically or by an operation on the display screen 4. become.

  When the sound output accompanying the execution of the display / sound output application 24 is a reproduction output of sound such as music, when the display / sound output application 24 changes from the active application 24 to the inactive application 24, The reproduction of the sound may be stopped, or the sound may not be output from the second sound output unit 9, but the reproduction of the sound may be continued inside the electronic device 100.

<Switching the application that outputs sound>
In the electronic device 100 according to the present embodiment, when a plurality of display / sound output applications 24 are executed, the user can change the application 24 in which the second sound output unit 9 outputs sound. It is like that. That is, the user can change the active application 24. In the present embodiment, when a plurality of display / sound output applications 24 are executed and the case operation detection unit 240 detects a user's predetermined operation on the electronic device 100, the sound output control unit 206 The two-sound output unit 9 changes the display / sound output application 24 that outputs sound. Hereinafter, an operation on the electronic device 100 for changing the display / sound output application 24 in which the second sound output unit 9 outputs sound is referred to as “sound output change operation”.

  As the sound output change operation detected by the case operation detection unit 240, for example, an operation of shaking the electronic device 100 can be employed. For example, when the casing operation detection unit 240 detects an operation in which the electronic device 100 is shaken a plurality of times, for example, twice within a predetermined time, the sound output control unit 206 performs two display / sound outputs being executed. The inactive application 24 among the applications 24 is changed to the active application 24. At this time, the direction in which the electronic device 100 is shaken is not limited. Accordingly, the active application 24 is changed even when the electronic device 100 is shaken a plurality of times in the vertical direction for the user, and the active application 24 is also changed when the electronic device 100 is shaken a plurality of times in the horizontal direction for the user. Will be changed. The active application 24 is also changed when the electronic device 100 is shaken once in the upward direction for the user and then once in the right direction for the user. When the casing operation detection unit 240 detects again an operation in which the electronic device 100 is shaken a plurality of times within a predetermined time, the sound output control unit 206 causes the two display / sound output applications 24 to be executed. Among them, the inactive application 24 is changed to the active application 24.

  As described above, the user can change the active application 24 by shaking the electronic device 100 a plurality of times within a predetermined time. Note that “directions” such as the upward direction and the right direction that appear in the following description are directions for the user, more specifically, a user when the user who has the electronic device 100 views the electronic device 100. It means the direction for.

  FIG. 8 is a diagram illustrating a state in which the electronic device 100 illustrated in FIG. 7 is shaken in the vertical direction. In the example of FIG. 8, the user is holding the electronic device 100 with both hands and waving up and down. Note that the user may hold the electronic device 100 with one hand.

  When the electronic device 100 shown in FIG. 7 is shaken once by the user, for example, once in the upward direction, as shown in FIG. The playback application is changed to the music playback application, and the active screen 4 is changed from the second display screen 4b to the first display screen 4a. Therefore, as shown in FIG. 9, the active screen specifying line 300 is displayed on the first display screen 4a, and the home key 10a, the menu key 10b, and the back key 10c included in the first operation unit 10 are lit. To come. After that, when the electronic device 100 shown in FIG. 9 is shaken twice by the user, the electronic device 100 returns to the state of FIG.

  Other operations may be adopted as the sound output changing operation. For example, as the sound output change operation, among the plurality of display / sound output applications 24 being executed, the display / sound output application 24 (inactive application 24) that is not outputting sound by the second sound output unit 9 is executed. An operation in which the electronic device 100 is shaken in the direction in which the display screen 4 (inactive screen 4) on which the accompanying display is performed may be employed. In this case, when the case operation detection unit 240 detects the operation, the sound output control unit 206 executes the active application 24 on the display screen 4 that exists in the direction in which the electronic device 100 is swung in the operation. Then, the display / sound output application 24 is displayed. In the present embodiment, the casing operation detection unit 240 causes the electronic device 100 to be moved a plurality of times, for example, twice in a predetermined time in the direction in which the display screen 4 on which the display associated with the execution of the inactive application 24 is present. When the shake operation is detected, the inactive application 24 becomes the active application 24.

  FIG. 10 is a diagram illustrating a state in which the electronic device 100 illustrated in FIG. 7 is shaken twice in the direction in which the first display screen 4a on which display is performed in accordance with the execution of the inactive application 24 is present. As shown in FIG. 10, when the electronic device 100 shown in FIG. 7 is shaken twice within a predetermined time in the direction (upward direction) in which the first display screen 4a exists, the active application 24 becomes a moving image with sound. The image playback application is changed to a music playback application that is displayed on the first display screen 4a as it is executed.

  After that, as shown in FIG. 11, when the electronic device 100 is shaken twice within a predetermined time in a direction (downward) in which the second display screen 4 b that is the inactive screen 4 exists, the active application 24 is The music playback application is changed to a moving image playback application with sound that is displayed on the second display screen 4b as it is executed.

  As shown in FIG. 12, when the electronic device 100 is held by the user so that the first display screen 4a and the second display screen 4b are arranged in the left-right direction, the case operation detection unit 240 is inactive. When an operation in which the electronic device 100 is shaken twice within a predetermined time in the direction in which the first display screen 4a that is displayed in accordance with the execution of the music playback application that is the application 24 is present, that is, in the right direction, is detected. The application becomes the active application 24. Thereafter, as shown in FIG. 13, the direction in which the second display screen 4b on which the display according to the execution of the moving image reproduction application with sound, which is the inactive application 24, is performed by the housing operation detection unit 240 exists. That is, when an operation in which the electronic device 100 is shaken twice within a predetermined time in the left direction is detected, the moving image reproduction application with sound becomes the active application 24. When the electronic device 100 is held by the user such that the first display screen 4a and the second display screen 4b are arranged in the left-right direction, for example, the active screen specifying line 300 is displayed at the lower end of the active screen 4.

  As described above, in the present embodiment, the user can change the application 24 that the second sound output unit 9 outputs sound by shaking the electronic device 100, so that the user can easily apply to the electronic device 100. The application 24 that outputs sound by operation can be changed. Therefore, the operability for the electronic device 100 is improved.

  As the sound output changing operation, an operation in which the posture of the electronic device 100 is changed is employed in addition to or instead of the operation of shaking the electronic device 100 described with reference to FIGS. You may do it.

  For example, as the sound output changing operation, an operation in which the electronic device 100 is turned over (turned over) and returned to the original may be employed. In this case, for example, when the casing operation detection unit 240 detects an operation in which the electronic device 100 is turned over as shown in FIG. 14 from the state of FIG. 7 and returned to the state of FIG. However, as shown in FIG. 9 described above, the moving image playback application with sound is changed to the music playback application. That is, the active screen 4 is changed from the second display screen 4b to the first display screen 4a.

  Further, as the sound output changing operation, in addition to the operation in which the electronic device 100 is turned over and returned to the original position, or in place of the operation, the operation in which the electronic device 100 is tilted from the current posture and returned to the original position may be adopted. good. At this time, the active application 24 may be changed only when the electronic device 100 is tilted rearward and returned to the original position, and the electronic device 100 is not limited to the direction in which the electronic device 100 is tilted. The active application 24 may be changed whenever the 100 is tilted back. FIG. 15 is a diagram illustrating a state in which the user 400 changes the active application 24 by tilting the electronic device 100 backward (backward) and returning it to the original state. In FIG. 15, the electronic device 100 before being tilted backward is indicated by a solid line, and the electronic device 100 tilted backward is indicated by a wavy line.

  As described above, the user can change the application 24 that the second sound output unit 9 outputs sound by simply tilting the electronic device 100 and returning the original, so that the user can output the sound with a simple operation on the electronic device 100. It is possible to change the application 24 that performs the above. Therefore, the operability for the electronic device 100 is improved.

<Volume adjustment of the second sound output unit>
Next, the volume adjustment of the second sound output unit 9 will be described. In the present embodiment, when the casing operation detection unit 240 detects a predetermined operation different from the above sound output change operation on the electronic device 100, the sound output control unit 206 determines the volume of the second sound output unit 9. Is supposed to change. Hereinafter, this “predetermined operation different from the sound output changing operation” is referred to as “volume changing operation”.

  As the volume change operation, for example, an operation in which the electronic device 100 is shaken can be employed. For example, when the case operation detection unit 240 detects an operation in which the electronic device 100 is shaken only once within a predetermined time, the sound output control unit 206 increases the volume of the second sound output unit 9 by a predetermined amount. . After that, when the operation that the electronic device 100 is shaken only once within a predetermined time is detected again in the housing operation detection unit 240, the sound output control unit 206 further increases the volume of the second sound output unit 9 by a predetermined amount. Just make it bigger. When the volume of the second sound output unit 9 is maximum, the sound output control unit 206 detects that the case operation detection unit 240 detects an operation in which the electronic device 100 is shaken only once within a predetermined time. The volume of the two-sound output unit 9 is reduced by a predetermined amount. Thereafter, when the casing operation detection unit 240 detects an operation in which the electronic device 100 is shaken only once within a predetermined time, the sound output control unit 206 further increases the volume of the second sound output unit 9 by a predetermined amount. Make it smaller. Then, when the sound volume of the second sound output unit 9 is minimum, the sound output control unit 206 detects, in the case operation detection unit 240, an operation in which the electronic device 100 is shaken only once within a predetermined time. The volume of the second sound output unit 9 is increased by a predetermined amount. Thereafter, the sound output control unit 206 operates in the same manner.

  Thus, in the present embodiment, the volume of the second sound output unit 9 increases every time the electronic device 100 is shaken once, and every time the electronic device 100 is shaken once the volume is maximized. The volume of the second sound output unit 9 is reduced. When the volume of the electronic device 100 is minimized, the volume of the second sound output unit 9 is increased every time the electronic device 100 is shaken once. In this case, the direction in which the electronic device 100 is shaken is not limited. Therefore, the volume of the second sound output unit 9 changes even if the electronic device 100 is shaken once in the upward direction, and changes even if the electronic device 100 is shaken once in the right direction.

  As the volume change operation, an operation different from the above operation may be employed. For example, an operation in which the electronic device 100 is shaken a predetermined number of times in a predetermined direction within a predetermined time may be adopted as the volume changing operation. In this case, for example, when the case operation detection unit 240 detects an operation in which the electronic device 100 is shaken only once in a predetermined direction (for example, upward) within a predetermined time, the sound output control unit 206 The volume of the second sound output unit 9 is increased by a predetermined amount. When the case operation detection unit 240 detects an operation in which the electronic device 100 is shaken only once in a predetermined time in a direction opposite to the specific direction (for example, downward), the sound output control unit 206 The volume of the two-sound output unit 9 is reduced by a predetermined amount.

  FIG. 16 is a diagram illustrating a state in which the electronic device 100 illustrated in FIG. 7 is shaken only once upward by a user within a predetermined time. As shown in FIG. 16, when the electronic device 100 shown in FIG. 7 is shaken only once in the upward direction within a predetermined time, the sound output from the second sound output unit 9 (on the second display screen 4b). The volume of the sound associated with the displayed moving image is increased by a predetermined amount. At this time, as shown in FIG. 16, a volume display graphic 350 indicating the volume of the second sound output unit 9 is displayed on the active screen 4 for a predetermined time, and the volume after the change is displayed on the volume display graphic 350. Also good.

  In the present embodiment, the volume of the second sound output unit 9 can be set, for example, from the 0th stage to the 5th stage, and when set to the 0th stage, from the second sound output unit 9 Does not output sound. When the electronic device 100 is shaken only once in the upward direction within a predetermined time, the volume of the second sound output unit 9 is increased, for example, by one level.

  The volume display graphic 350 is configured by arranging five squares 350a in a line so as to be adjacent to each other. In these five squares 350 a, the display color changes from the left side by the number corresponding to the volume of the second sound output unit 9. When the volume of the second sound output unit 9 is in the 0th stage, the display colors of the five squares 350a are the same. With this display color as a reference, the volume of the second sound output unit 9 is 1 when the volume is in the 1st stage. The display color of the leftmost square 350a changes, and when the volume of the second sound output unit 9 is in the second stage, the display colors of the two squares 350a change from the left. When the volume of the second sound output unit 9 is in the third stage, the display color of the three squares 350a from the left changes. When the volume of the second sound output unit 9 is in the fourth stage, the four squares 350a from the left When the display color changes and the volume of the second sound output unit 9 is in the fifth stage, the display color of all the squares 350a changes. The volume display graphic 350 shown in FIG. 16 indicates that the volume of the second sound output unit 9 is set to the third stage.

  On the other hand, as shown in FIG. 17, when the electronic device 100 shown in FIG. 7 is shaken only once in a downward direction within a predetermined time, the volume of the sound output from the second sound output unit 9 is increased. Only a fixed amount, for example, one step is reduced. Also in this case, as shown in FIG. 17, a volume display graphic 350 indicating the volume after the change may be displayed on the active screen 4 for a predetermined time.

  As described above, in the present embodiment, the user can change the volume of the second sound output unit 9 only by shaking the electronic device 100 in a manner different from the case of changing the active application 24. Can change the volume of the second sound output unit 9 with a simple operation on the electronic device 100. Therefore, the operability for the electronic device 100 is improved.

  Note that, as the volume changing operation, in addition to or in place of the operation of shaking the electronic device 100 described above, an operation of changing the posture of the electronic device 100 may be employed.

  For example, as the sound volume changing operation, an operation in which the electronic device 100 is tilted from the current posture may be employed. In this case, for example, when the housing operation detection unit 240 detects that the electronic device 100 is tilted rearward (backward) and the posture of the electronic device 100 is not returned within a predetermined time, the sound The output control unit 206 increases the volume of the second sound output unit 9 by a predetermined amount. On the other hand, when the casing operation detection unit 240 detects that the electronic device 100 is tilted forward (front side) and the posture of the electronic device 100 is not returned within a predetermined time, the sound output control unit 206 The volume of the second sound output unit 9 is reduced by a predetermined amount.

  FIG. 18 is a diagram illustrating a state in which the user 400 adjusts the volume of the second sound output unit 9 by tilting the electronic device 100 in the front-rear direction. In FIG. 18, the electronic device 100 before being tilted is indicated by a solid line, the electronic device 100 tilted backward is indicated by a wavy line, and the electronic device 100 tilted forward is indicated by a one-dot chain line. Has been.

  As described above, the user can change the volume of the second sound output unit 9 only by changing the attitude of the electronic device 100 in a manner different from the case where the active application 24 is changed. The volume of the second sound output unit 9 can be changed with a simple operation on the device 100. Therefore, the operability for the electronic device 100 is improved.

<Various modifications>
<First Modification>
In the above example, when a plurality of display / sound output applications 24 are executed, the display associated with the execution is performed on each of the plurality of display screens 4. Only the display associated with the execution of the active application 24 among the output applications 24 may be performed using all of the plurality of display screens 4. In this case, although the inactive application 24 is executed, display and sound output associated with the execution are not performed.

  FIG. 19 shows that the electronic device 100 shown in FIG. 7 described above uses only the first display screen 4a and the second display screen 4b only for the display accompanying the execution of the moving image playback application with sound, which is the active application 24. It is a figure which shows a mode that it is performed. In this case, as shown in FIG. 7, the moving image is displayed larger than the case where the display associated with the execution of the moving image reproduction application with sound is performed using only the second display screen 4b. become. Further, the active screen specifying line 300 is displayed on both the first display screen 4a and the second display screen 4b. In each of the first operation unit 10 and the second operation unit 11, a plurality of operation keys are lit.

  Thereafter, as shown in FIG. 7, in the electronic device 100, an operation mode in which the display associated with the execution of the plurality of display / sound output applications 24 being executed is performed on each of the plurality of display screens 4 is “one screen mode”. Call it. On the other hand, as shown in FIG. 19, in the electronic device 100, only the display associated with the execution of the active application 24 among the plurality of display / sound output applications 24 being executed is all of the plurality of display screens 4. An operation mode performed using is called “multiple screen mode”.

  Switching from the single screen mode to the multiple screen mode and switching from the multiple screen mode to the single screen mode in the electronic device 100 is performed by operating the first operation unit 10, the second operation unit 11, and the display screen 4. be able to. For example, in the electronic device 100 shown in FIG. 7, when the user operates the menu key 11 b that is lit on the second operation unit 11, the menu screen is displayed on the second display screen 4 b. After that, when the user performs a predetermined operation on the menu screen, the electronic device 100 changes from the single screen mode to the multiple screen mode shown in FIG.

  In addition, in the electronic device 100 shown in FIG. 19, when the user operates the menu key 10b that is lit on the first operation unit 10, the menu screen is displayed on the first display screen 4a. When the user performs a predetermined operation on this menu screen, electronic device 100 changes from the multiple screen mode to the single screen mode shown in FIG. Similarly, when the user operates the menu key 11b that is lit on the second operation unit 11, a menu screen is displayed on the second display screen 4b. When the user performs a predetermined operation on the menu screen, the electronic device 100 changes from the multiple screen mode to the single screen mode.

  In the electronic apparatus 100 in the multi-screen mode, when the casing operation detection unit 240 detects the sound output change operation, the active application 24 is changed, and the display associated with the execution of the active application 24 after the change is displayed on the plurality of display screens 4. All of this is done. For example, in the electronic device 100 shown in FIG. 19, when the casing operation detection unit 240 detects a sound output change operation, the active application 24 is changed from a moving image playback application with sound to a music playback application, and the music playback application is executed. The accompanying display is performed from the first display screen 4a to the second display screen 4b.

  Further, in the electronic device 100 in the one-screen mode, when the casing operation detection unit 240 detects the sound output change operation, the active application 24 is changed, and the electronic device 100 is changed from the one-screen mode to the multi-screen mode. good. For example, in the electronic device 100 shown in FIG. 9 described above, when the casing operation detection unit 240 detects a sound output change operation, the active application 24 changes from a music playback application to a moving image playback application with sound, and the electronic device 100 Changes from the single-screen mode to the multi-screen mode, and the state shown in FIG. 19 is obtained.

  Further, when the electronic device 100 is switched from the single screen mode to the multiple screen mode, and the display accompanying the execution of the inactive application 24 is a moving image reproduction display, the reproduction of the moving image is stopped. Alternatively, the moving image may be reproduced inside the electronic device 100.

  In addition, when the electronic device 100 is switched from the single screen mode to the multiple screen mode, the sound output accompanying the execution of the display / sound output application 24 that is the inactive application 24 is a reproduction output of sound such as music. In that case, the reproduction of the sound may be stopped, or the sound may be reproduced inside the electronic device 100.

<Second Modification>
In the above example, in the electronic device 100 executing the plurality of display / sound output applications 24, when the case operation detection unit 240 detects the sound output change operation, the active application 24 is changed. In addition, or instead of this, when the screen operation detection unit 220 detects a sound output change operation, the active application 24 may be changed. This modification will be described below.

  In the electronic device 100 executing the plurality of display / sound output applications 24, the screen operation detection unit 220 displays the display screen 4 that is displayed in association with the execution of the inactive application 24, that is, the inactive screen 4 by the user. When a predetermined screen operation is detected, the sound output control unit 206 displays the application 24 for which the second sound output unit 9 outputs a sound on the display screen 4 (inactive screen 4) on which the predetermined screen operation is performed. The display is changed to the application 24 that is displayed along with the execution. Hereinafter, among the sound output change operations, a predetermined screen operation for the display screen 4 for changing the application 24 for which the second sound output unit 9 outputs sound is referred to as “sound output change screen operation”.

  For example, in the electronic device 100 shown in FIG. 7 described above, as shown in FIG. 20, the user can display the first display screen 4 a that is displayed in accordance with the execution of the music playback application that is the inactive application 24. When the user performs the sound output change screen operation with the finger 500, as shown in FIG. 9 described above, the active application 24 is the first display screen on which the sound output change screen operation is performed from the moving image playback application with sound. 4a is changed to the application 24 that is displayed along with the execution, that is, the music reproduction application. Note that the user may operate the display screen 4 using screen operation means other than his / her finger 500, for example, a pen-like member.

  As the sound output change screen operation, a touch operation, a tap operation, or a flick operation can be adopted. Here, the touch operation is an operation in which screen operation means (such as a finger or a pen-like member) contacts the display screen. Therefore, when the touch operation is adopted as the sound output change screen operation, the sound output control unit 206 detects that the screen operation detection unit 220 detects that the screen operation means has come into contact with the inactive screen 4, and the non-operation is performed. An application 24 that is displayed on the active screen 4 as it is executed is referred to as an active application 24. Of the touch operations, an operation in which the screen operation means makes contact with the display screen for more than a predetermined time without changing the contact location is referred to as a “long touch operation”.

  Further, the tap operation is an operation from when the screen operation means touches the display screen until the touched part leaves without changing. Therefore, when the tap operation is adopted as the sound output change screen operation, the sound output control unit 206 confirms that the screen operation means has come into contact with the inactive screen 4 and the contact location has been left unchanged. When the screen operation detection unit 220 detects, the application 24 displayed on the inactive screen 4 in accordance with the execution is set as the active application 24.

  In addition, the flick operation is a predetermined distance from the time when the screen operation means comes into contact with the display screen to the time when the screen operation means leaves the display screen, and the time when the screen operation means comes into contact with the display screen after leaving This is the movement operation. Therefore, when the flick operation is adopted as the sound output change screen operation, the sound output control unit 206 is within a predetermined time until the screen operation means comes into contact with the inactive screen 4 and leaves, and the screen operation When the screen operation detection unit 220 detects that the means has moved a predetermined distance or more before contacting and leaving the inactive screen 4, the application 24 displayed on the inactive screen 4 is displayed. The active application 24 is assumed.

  In this way, the user can set the application 24 displayed on the inactive screen 4 to be the active application 24 by performing an operation on the inactive screen 4. Therefore, the user can change the active application 24 to the desired application 24 with a simple operation on the electronic device 100. Therefore, the operability for the electronic device 100 is improved.

<Third Modification>
In the above example, when the casing operation detection unit 240 detects a volume change operation, the volume of the second sound output unit 9 is changed. However, in addition to or instead of this, the screen operation detection unit 220 is changed. When a predetermined screen operation is detected, the volume of the second sound output unit 9 may be changed. For example, the sound output control unit 206 may change the volume of the second sound output unit 9 when the screen operation detection unit 220 detects a long tap operation on the active screen 4. In this case, the volume of the second sound output unit 9 is gradually changed while the screen operation means is in contact with the active screen 4.
