For example, when the tablet computer 10 is not used, the user can set the tablet computer 10 to a standby state using the touch panel 191 or the hard key 192 of the input unit 190.

  When it is determined that the tablet computer 10 is set to the standby state (YES in step S202), the control unit 100 sets the gain of the amplifier 210 to the maximum (step S203). Next, the control unit 100 rings the speaker 220 via the amplifier 210 based on the received emergency information, and notifies the user of the emergency information at the maximum volume (first volume) (step S204).

  In this case, there is a high possibility that the user does not have the tablet computer 10 or the tablet computer 10 is placed away from the user. Therefore, even if the emergency information is notified at the maximum volume, the user is less likely to be stressed. In addition, the user can sufficiently recognize that the emergency information has been received even if the tablet computer 10 is placed at a location away from the user.

  On the other hand, when it is determined that the tablet computer 10 is not in the standby state (NO in step S202), the control unit 100 sets the gain of the amplifier 210 to a predetermined value that provides a medium volume (step S205). Next, the control unit 100 rings the speaker 220 via the amplifier 210 to notify the user of emergency information at a medium volume (second volume) (step S204).

  In this case, the user is likely to be using the tablet computer 10 or in a place where it can be used immediately. Therefore, the user can sufficiently recognize that the emergency information has been received even at a medium volume level, and the volume level is set to a medium level, so that the user does not feel great stress. . In addition, the tablet computer 10 can notify emergency information with the minimum necessary power consumption.

  FIG. 3 is a flowchart illustrating the processing procedure of the tablet computer 10 according to the second embodiment.

When receiving the emergency information (step S301), the control unit 100 determines whether or not there is an input operation by the user a predetermined time before the reception (step S302). The elapsed time from the input operation to reception can be obtained by measuring the time from when the user operated the input unit 190.

When it is determined that a predetermined time or more has elapsed since the previous input operation (step S302)
NO), the control unit 100 sets the gain of the amplifier 210 to the maximum (step S303), rings the speaker 220, and notifies the emergency information to the user at the maximum volume (first volume) (step S304).

  In this case, since the input operation is not performed for a long time, the user may not have the tablet computer 10 or the tablet computer 10 may be placed at a position away from the user. high. Therefore, as in the case of the first embodiment, even if the emergency information is notified at the maximum volume, there is little risk of stressing the user. Even if the tablet computer 10 is placed away from the user, it is possible to fully recognize that the emergency information has been received.

  On the other hand, when it is determined that the input operation is performed before the predetermined time for receiving the emergency information (YES in step S302), the control unit 100 sets the gain of the amplifier 210 to a predetermined value at which the volume is medium. (Step S305), the speaker 220 is sounded, and the emergency information is notified to the user at a medium volume (second volume) (Step S304).

  In this case, the user is likely to be using the tablet computer 10 or in a place where it can be used immediately. Therefore, the user can sufficiently recognize that the emergency information has been received even at a medium volume level, and the volume level is set to a medium level, so that the user does not feel great stress. . In addition, the tablet computer 10 can notify emergency information with the minimum necessary power consumption.

  FIG. 4 is a flowchart illustrating the processing procedure of the tablet computer 10 according to the third embodiment.

  Upon receiving emergency information (step S401), the control unit 100 acquires a vibration detection signal from the vibration sensor 160, or acquires an angle change detection signal from the angle sensor 170, and whether there is vibration or whether there is an angle change. Is determined (step S402).

  When vibration or angle change is not detected (NO in step S402), the control unit 100 sets the gain of the amplifier 210 to the maximum (step S403), rings the speaker 220, and sets emergency information at the maximum volume (first volume). The user is notified (step S404).

  In this case, since the tablet computer 10 does not vibrate or does not change in angle, the user can determine that he / she does not have the tablet computer 10. Therefore, even if the emergency information is notified at the maximum volume, the user is less likely to be stressed. In addition, the user can sufficiently recognize that the emergency information has been received even if the tablet computer 10 is placed at a location away from the user.

  On the other hand, when the vibration or angle change of the tablet computer 10 is detected (YES in step S402), the control unit 100 sets the gain of the amplifier 210 to a predetermined value that provides a medium volume (step S405), and the speaker 220. To notify the user of emergency information at a medium volume (second volume) (step S404).

In this case, the user is likely to have the tablet computer 10, and thus the user can sufficiently recognize that the emergency information has been received even at a medium volume. . Moreover, since the volume is set to a medium level, there is no great stress. In addition, the tablet computer 10 can notify emergency information with the minimum necessary power consumption.

  FIG. 5 is a flowchart illustrating the processing procedure of the tablet computer 10 according to the fourth embodiment.

  When receiving the emergency information (step S501), the control unit 100 acquires a detection signal from the human sensor 180 and determines whether or not the user has the tablet computer 10 (step S502).

  If no person is detected (NO in step S502), the control unit 100 sets the gain of the amplifier 210 to the maximum (step S503), rings the speaker 220, and sends the emergency information to the user at the maximum volume (first volume). Notification is made (step S504).

  In this case, since the human sensor 180 does not detect the user, it can be determined that the user does not have the tablet computer 10. Therefore, even if the emergency information is notified at the maximum volume, the user is less likely to be stressed. Even if the tablet computer 10 is placed away from the user, it is possible to fully recognize that the emergency information has been received.

  On the other hand, when a person is detected by the human sensor 180 (YES in step S502), the control unit 100 sets the gain of the amplifier 210 to a predetermined value with a medium volume (step S505), and causes the speaker 220 to ring. Then, the emergency information is notified to the user at a medium volume (second volume) (step S504).

  In this case, the user possesses the tablet computer 10, and therefore the user can sufficiently recognize that the emergency information has been received even at a medium volume. Moreover, since the volume is set to a medium level, there is no great stress. In addition, the tablet computer 10 can notify emergency information with the minimum necessary power consumption.

  FIG. 6 is a flowchart illustrating the processing procedure of the tablet computer 10 according to the fifth embodiment.

  When receiving the emergency information (step S601), the control unit 100 determines whether or not the tablet computer 10 is in a standby state (step S602).

  If it is determined that the tablet computer 10 is set to the standby state (YES in step S602), the control unit 100 sets the gain of the amplifier 210 to the maximum (step S603), causes the speaker 220 to ring, and provides emergency information. Is notified to the user at the maximum volume (first volume) (step S604).

  In this case, there is a high possibility that the user does not have the tablet computer 10 or the tablet computer 10 is placed away from the user. Therefore, as in the case of the first embodiment, even if the emergency information is notified at the maximum volume, there is little risk of stressing the user. In addition, the user can sufficiently recognize that the emergency information has been received even if the tablet computer 10 is placed at a location away from the user.

On the other hand, when it is determined that the tablet computer 10 is not in the standby state (NO in step S602), the control unit 100 determines whether power is supplied to the tablet computer 10 from an external power source. (Step S605). This determination can be performed by the external power input state detection unit 120. That is, the external power input state detection unit 120 detects whether or not a power cord plug is connected to the power cord connection connector of the external power input unit 110. If the power cord plug is connected, the connection state detection is performed. The signal is output to the control unit 100.

  When it is not in the standby state (NO in step S602) and it is detected that power is supplied from the external power supply (YES in step S605), the control unit 100 sets the gain of the amplifier 210 to the maximum (step S603). ), The speaker 220 is sounded, and the emergency information is notified to the user at the maximum volume (first volume) (step S605).

  In this case, the tablet computer 10 is not set to the standby state, and is in a state where each function including the display unit 130 is operated with the external power supply connected. This state can be assumed, for example, when the user installs the tablet computer 10 in a bedroom or living room and uses it as a digital photo frame for displaying a desired photograph on the display unit 130. Therefore, since the user does not have the tablet computer 10 and the tablet computer 10 is located some distance away from the user, even if the emergency information is notified at the maximum volume, the user can be notified. There is little risk of stress. In addition, the user can sufficiently recognize that the emergency information has been received even if the tablet computer 10 is placed at a location away from the user.

  Further, when not in the standby state (NO in step S602) and no electric power is supplied from the external power source (NO in step S605), the control unit 100 sets the gain of the amplifier 210 to a predetermined value that provides a medium volume. (Step S606), the speaker 220 is sounded, and emergency information is notified to the user at a medium volume (second volume) (step S605).

  In this case, there is a high possibility that the user is carrying and using the tablet computer 10, and therefore the user fully recognizes that the emergency information has been received even at a medium volume. be able to. Moreover, since the volume is set to a medium level, there is no great stress. In addition, the tablet computer 10 can notify emergency information with the minimum necessary power consumption.
