The central control unit 11 acquires the ambient noise level as one of the above-described control conditions. If the ambient noise level is high, the sound speaker 23 is detected. The voice output is not suppressed.

FIG. 3 is a diagram for explaining the content storage unit M3.
The content storage unit M3 stores music / videos downloaded from the content distribution device 4, and stores recorded (recorded, recorded) TV programs and radio programs. The content storage unit M3 stores “ID”, “type”, Each item includes “recording date”, “related information”, “actual data”, and “pause flag”. “ID” is an item for storing a series No. for identifying content, and “type” is information indicating the type of content, for example, music, video, recorded television program, recorded radio program, and the like. The item “recording date and time” is an item for storing the date and time when the content is recorded.

“Related information” is an item for storing information related to content, such as a song name and singer name for music, and a program name, broadcast date and time, channel number, performer, etc. for a recorded TV program. . “Real data” is an item for storing actual content data. The “pause flag” is an item for storing a flag indicating that the reproduction of the content is paused. When the central control unit 11 suppresses the sound output to the sound speaker 23 due to disconnection of the headphones 10 during the reproduction of the content, the central control unit 11 pauses the reproduction of the content and turns on the “pause flag”. I have to.

FIG. 4 is a diagram for explaining the operation mode information storage unit M4.
The operation mode information storage unit M4 stores an operation mode that is one of the above-described control conditions, and includes items of “ID”, “content”, and “setting flag”. “ID” is an item for storing a series No. for identifying an operation mode, and “content” is an item for storing an operation mode as the above-described control condition. For example, “normal mode”, “emergency mode”, “radio wave” "Off mode", "Power saving mode", etc. are set. “Setting flag” indicates that the currently effective operation mode is selectively set by a user operation, and when the value is “1”, it indicates that the operation mode is currently effective.

Here, the “emergency mode” is an operation mode in which, in addition to the normal operation, an operation of periodically acquiring its own location information and transmitting it to a specific partner and giving the highest priority to incoming calls from a specific partner Thus, it is arbitrarily set by a user operation. Note that when an emergency number (110, 119, etc.) is called, the “emergency mode” may be automatically set. The “radio wave off mode” is a mode in which communication with the base station is prohibited. Other communication, that is, a GPS satellite 7, a transmission antenna 6, a ticket gate device as a public transportation device 9, and an in-vehicle device 8 for a private vehicle. Is not restricted in the “radio wave off mode”.

The “radio wave off mode” is arbitrarily set by a user operation, but may be automatically set when the use of public transportation is detected. `` Power saving mode '' is a mode that suppresses power consumption by increasing the communication interval with the base station, lowering the volume, or reducing the brightness of the display unit, and is arbitrarily set by user operation It is. As long as there is no contradiction in the operation other than the normal mode, a plurality of operation modes such as a radio wave off mode and a power saving mode may be set as currently effective modes. The “normal mode” is an operation mode other than the special mode such as the “emergency mode”, “radio wave off mode”, and “power saving mode” described above.

FIG. 5 is a diagram for explaining the usage history storage unit M5.
The usage history storage unit M5 stores the usage status of private vehicles and public transportation (trains, buses, airplanes, etc.) as its usage history. “ID”, “type”, “use date / time”, “use fee” "," Balance "," Related information ", and" In-use flag ". “ID” is an item for storing a series No. for identifying the use status of transportation facilities, and “Type” is an item for storing private cars, trains, buses, and the like as information indicating the types of transportation facilities. “Use date and time” is an item for storing the date and time of use of the transportation facility (use start date and time and use end date and time).

“Usage fee” is an item for storing a payment amount when using a transportation facility. However, when a private car is used, it is not necessary to store the “usage fee”. “Balance” is the balance of the electronic money charged to the ticket function that performs the fee settlement processing of the transportation system. Every time the public transportation is used, the central control unit 11 reduces the “usage fee” from the “balance”. The balance update process is performed. “Related information” stores, for example, information related to transportation such as a use start station, use end station, and route name in the case of a train, and a use start airport, use end airport, and flight number in the case of an airplane. It is an item to be. The “in-use flag” is a flag indicating that the transportation facility is being used. If it is in use, it is turned on and its value becomes “1”.

FIG. 6 is a diagram for explaining the control condition storage unit M6.
The control condition storage unit M6 stores a control condition for controlling whether or not to suppress the sound output to the sound speaker 23 when the connection of the headphones 10 is disconnected during the sound output to the headphones 10. Each item includes “ID”, “item”, “content”, and “setting flag”. “ID” is an item for storing a series of Nos for identifying control conditions. “Item” is an item for storing, for example, “transportation”, “application”, “operation mode”, “ambient volume”, “date / time”, “position”, and the like as condition items.

“Content” indicates the specific content of the item. For example, “content” of the control condition “train, suppress” suppresses the sound output to the sound speaker 23 when the headphones 10 are disconnected while using the train, but if the train is not used, the sound is suppressed. This means that the output is not suppressed. “Private vehicle, do not suppress” does not suppress the sound output to the sound speaker 23 even if the headphone 10 is disconnected while using the private vehicle, but suppresses the sound output if the private vehicle is not used. It means that. The same applies to “application”, “operation mode”, “ambient volume”, “date / time”, “position”, and the like of other “items”.

That is, when “item” is “application” and “content” is “emergency notification application (application), not suppressed”, sound output to the sound speaker 23 is performed even if the headphones 10 are disconnected during the operation of the emergency notification application. Does not suppress, but otherwise it means suppress. In addition, when “item” is “date and time” and “content” is “23: 0 to 5:00”, the output of sound to the sound speaker 23 is suppressed when the headphones 10 are disconnected from midnight to the morning time. This means that even if it is out of time, it will not be suppressed.

The “setting flag” is for selectively setting a currently effective control condition by a user operation, and when the value is “1”, it indicates that the current effective control condition. In the control condition storage unit M6, only the condition for “suppressing” may be set as the suppression condition, or only the condition for “not suppressing” may be set. In addition, when both of the conditions for “suppress” and the condition for “not suppress” are satisfied, whether to suppress or not may be determined in advance, or the priority order of the conditions may be determined. In addition, the content of the higher priority condition may be followed.

Next, the operation concept of the mobile phone 1 in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 7 is a flowchart showing an outline of the overall operation of the mobile phone 1.
First, when a power-on operation for turning on the power is performed (YES in step A1), the central control unit 11 starts power supply and executes a power-on process for initializing a predetermined memory and the like. A standby process is performed in which a standby image is read and displayed, or a location registration is performed by communicating with the base station 2A (step A2). Then, the operation unit 20 is accessed to check the presence / absence of the operation, and it is checked whether a setting operation for instructing information setting has been performed (step A3). Now, when a setting operation is performed, as a setting process according to the setting operation, for example, a process of setting the “setting flag” or the like in the operation mode information storage unit M4 and the control condition storage unit M6 is performed (step S1). A4). Thereafter, the process returns to step A3.

When the use of the transportation facility is detected between the public transportation apparatus 9 and the short-range communication unit 18 (YES in step A5), the use processing is executed (step A6), and then the above-described step A3 is performed. Return. As will be described in detail later, this usage process is a process of paying charges, storing a usage history, and the like according to the use of the transportation facility. When an operation for instructing the reproduction of the content is performed (YES in step A7), the reproduction process is executed (step A8), and then the process returns to step A3 described above. As will be described in detail later, this reproduction process is a process of switching the output destination depending on whether or not the headphones 10 are connected after starting the reproduction output of the content.

If it is detected that the headphone 10 is connected or disconnected (YES in step A9), headphone processing is executed in response thereto (step A10), and the process returns to step A3 described above. As will be described in detail later, this headphone processing is a result of determining whether or not the above-described control condition is satisfied when the headphones 10 are disconnected during audio output in which content is output to the headphones 10. This is a process of controlling whether or not to suppress the sound output to the sound speaker 23 based on the above, or releasing the suppression when the headphones 10 are connected while the sound output to the sound speaker 23 is being suppressed.

Further, when a release timer (not shown) that releases the suppression during the suppression of the sound output to the sound speaker 23 times out (YES in step A11), the release process is executed (step A12), and then the above-described steps Return to A3. This release timer is a timer that measures the timing (for example, 1 minute or 5 minutes) for releasing the suppression while the sound output to the sound speaker 23 is being suppressed. Moreover, even if the headphones 10 are not connected during the suppression of the sound output to the sound speaker 23, the cancellation process is a process for canceling the suppression when the cancellation timer times out while the suppression is being performed. It is.

When an incoming call is detected (YES in step A13), the incoming call process for storing the call history or the received mail is executed (step A14), and the call process is executed or the contents of the received mail are displayed. After executing the process (step A15), the process returns to step A3 described above. When a power-off operation is performed (YES in step A16), a power-off process is executed (step A17), and this flow ends. When any other operation is performed (YES in step A18). ), For example, recording of TV programs and radio programs (recording and recording), downloading of contents, emergency notification application, TV playback application, radio playback application, termination of other playback applications, Transmission, mail transmission, etc. are performed (step A19).

Next, the use process described above (step A6 in FIG. 7) will be described in detail according to the flowchart in FIG.
First, the central control unit 11 determines whether the use detection of the transportation facility is detection of start of use or detection of end of use (step B1). Here, the detection of the start of use means that when a bid is detected by communication with the public transportation device 9, it is detected that the mobile phone 1 is connected to an in-vehicle device (such as a hands-free kit or a car navigation system) of a private car. When it is detected that a signal transmitted in a train, bus, airplane or private car is received. It may be when high-speed movement is detected by the in-vehicle device.

If the usage start is detected (YES in step B1), the fee settlement processing is executed at this point (step B2) if the fee system is to be settled at the start of usage. This charge settlement process is skipped when using a private car. Next, after storing each piece of information that can be acquired at the start of use such as “type”, “use date and time (use start date and time)” in the use history storage unit M5 (step B3), the “in-use flag” is set to “ 1 "(step B4).

The end of use is detected when the mobile phone 1 is removed from an in-vehicle device (such as a hands-free kit or a car navigation system) of a private car when a billing is detected by communication with the public transportation device 9. When it is detected that it is no longer possible to receive signals transmitted in trains, buses, airplanes, and private cars. If the use detection of the public transport apparatus 9 is a use end detection (NO in step B1), if it is a charge system that pays out at the end of use, a charge settlement process is executed at this point (step B5). ). This payment process is skipped when using a private car. Next, after storing information that can be acquired at the end of use, such as “use date and time (use end date and time)” in the use history storage unit M5 (step B6), the “in-use flag” is set to “0” (step B6). Step B7).

In this way, through the use processing (steps A5 and A6 in FIG. 7) executed in response to the use detection (detection of start of use / detection of end of use) of the transportation device 9, the fee is settled, the use history is being stored, and in use The flag is updated.

Next, the reproduction process described above (step A8 in FIG. 7) will be described in detail according to the flowcharts in FIGS.
First, the central control unit 11 determines whether the operation for reproducing the content is an operation for starting the emergency notification application (operation for reproducing the emergency notification sound) (step C1 in FIG. 9), or an operation for reproducing the television program / radio program. Whether it is an operation for reproducing the stored content or not (step C7). When an operation for starting the emergency notification application is performed (YES in step C1), the emergency notification application is started in response to the operation (step C2), and it is checked whether the headphones 10 are connected (step C3). If the headphones 10 are connected, output of sound (emergency notification sound) to the headphones 10 is started (step C4). If the headphones 10 are not connected (NO in step C3), the sound speaker 23 is connected. On the other hand, voice (emergency notification sound) output is started (step C5), and voice (emergency notification sound) output from the sound speaker 23 is started (step C6).

When an operation for playing a TV program / radio program is performed (YES in step C7), the TV receiver / radio player application is activated after the broadcast receiving unit 17 is activated in response (step S7). C8) The reception of the TV program / radio program is started (step C9). Then, TV video output is started on the display unit 19 (step C10), and video output from the display unit 19 is started (step C11). If the reproduction target is a radio program, the video output start step C10 and step C11 are skipped. In this state, it is checked whether or not the headphones 10 are connected (step C12). If the headphones 10 are connected, output of TV / radio audio to the headphones 10 is started (step C13), and the headphones 10 are connected. If not (NO in step C12), output of TV / radio audio to the sound speaker 23 is started (step C14), and TV / radio audio output from the sound speaker 23 is started (step C15).

When an operation for reproducing the stored content is performed (NO in step C7), the process proceeds to the flow of FIG. 10, and a reproduction application corresponding to the content to be reproduced is activated (step C16). In this case, if the stored content to be played is a radio program or music, the music playback application is started. If the stored content is a television program or video, the video playback application is started. Then, the content to be reproduced is read (step C17), and when video output is started to the display unit 19 (step C18), video output is started from the display unit 19 (step C19). If no video is included in the content as in a radio program, steps C18 and C19 for starting video output are skipped.

In this state, it is checked whether or not the headphones 10 are connected (step C20). If the headphones 10 are connected, sound output to the headphones 10 is started (step C21). If the headphones 10 are not connected, (NO in step C20), voice output to the sound speaker 23 is started (step C22), and voice output from the sound speaker 23 is started (step C23).

In this way, the reproduction processing executed in response to the content reproduction operation (steps A7 and A8 in FIG. 7) starts the reproduction output of the content, and the output destination depending on whether or not the headphones 10 are connected. Is switched.

Next, the above-described headphone processing (step A10 in FIG. 7) will be described in detail according to the flowcharts in FIGS.
First, the central control unit 11 determines whether the detection of the headphones 10 is a detection that the headphones 10 are connected or a detection that the headphones 10 are disconnected (step D1 in FIG. 11). Now, when it is detected that the headphones 10 are disconnected regardless of the intention / unwillingness in the state where the headphones 10 are connected (NO in step D1), the flow proceeds to FIG. It is checked whether output is in progress (step D23). Here, if the sound is not being output to the headphones 10, the headphone process is terminated. If the sound is being output (YES in step D 23), it is determined whether or not to suppress the sound output to the sound speaker 23. The process proceeds to the execution of the suppression determination process (step D24).

FIG. 13 is a flowchart for explaining the suppression determination process (step D24 in FIG. 12) in detail.
First, the central control unit 11 accesses the control condition storage unit M6, and “ID” is “D01” (
The control condition “item” is “transportation”) is read (step E1), and it is checked whether the “setting flag” has “content” of “1” (step E2), and the “setting flag” is “1”. If the "content" is not stored, the process proceeds to the next step E4. In the example of FIG. 6, “train, restraint” and “airplane, restraint” are stored as “contents” with “setting flag” being “1” (YES in step E2). The process proceeds to a determination process A for determining whether or not to suppress the sound output to the sound speaker 23 according to the history (step E3).

FIG. 14 is a flowchart for explaining in detail the above-described determination processing A (step E3 in FIG. 13).
First, the central control unit 11 accesses the usage history storage unit M5 to read the usage history (step F1), searches for a usage history with the “in-use flag” being “1”, and the “type” is “setting flag” Is satisfied (step F2), and if it is satisfied, it is determined whether or not the “content” of the control condition is “suppressed” (step F3).

Now, as in the example of FIGS. 5 and 6, the “history” of the usage history with the “in-use flag” being “1” is “train”, and the “content” of the control condition is “set flag” is “1”. If it is “Train, Suppress”, the condition of “Type” is satisfied (YES in Step F2) and the condition of “Suppress” is also satisfied (YES in Step F3). It is determined that the sound output to the terminal 23 is “suppressed” (step F4). Note that if the “content” of the control condition “setting flag” is “1” is, for example, “train, not suppressed” (NO in step F3), it is determined as “not suppressed” (step F5).

On the other hand, when “contents” of the control condition “setting flag” is “1” is “train, restraint”, a transportation system other than a train is being used (for example, a private car or a bicycle is being used or walking) If so (NO in step F2), it is checked whether the “content” of the control condition “setting flag” is “suppressed” (step F6). In the example of FIG. Since the “content” of the condition is “suppress” (YES in step F6), it is determined that “do not suppress” (step F5), but if the “content” is, for example, “not suppress” (step F6). NO), “decrease” is determined (step F4).

Note that when there are a plurality of “train, restraint” and “airplane, restrain” as the “content” of the control condition whose “setting flag” is “1” as in the example of FIG. The above operation is performed every time. Thus, while using the train, the control condition of “train, suppress” is satisfied (YES in steps F2 and F3), so it is determined as “suppress” (step F4), and the control condition of “airplane, suppress” is determined. Is not satisfied (NO in step F2, YES in step F6), it is determined that “do not suppress” (step F5). In this way, when both “suppress” and “not suppress” are determined using a plurality of control conditions, whether or not to suppress may be determined in advance as described above. Then, the priority order of the conditions may be determined and the contents of the higher priority conditions may be followed (the same applies hereinafter).

When such discrimination processing A (step E3 in FIG. 13) is completed, the central control unit 11 accesses the control condition storage unit M6, and its “ID” is “D02” (“item” is “application”). The control condition is read (step E4), and it is checked whether or not “content” with “1” as the “setting flag” is stored (step E5), and “content” with “1” as the “setting flag” is stored. If not, the process proceeds to the next step E7. In the example of FIG. 6, the “setting flag” of “emergency notification application, not suppressed” is “1” as the “content” of the control condition (YES in step E5). Then, the process proceeds to a determination process B for determining whether or not to suppress the sound output to the sound speaker 23 (step E6).

FIG. 15 is a flowchart for explaining the above-described determination process B (step E6 in FIG. 13) in detail.
Since this determination process B is basically the same process as the above-described determination process A, a detailed description thereof will be omitted. First, an operating application is detected (step G1), and it is checked whether the operating application satisfies the “content” of the control condition “setting flag” is “1” (step G2). Thereafter, the operation proceeds to the same operation as in the above-described discrimination process A. Now, if the application in operation is “emergency notification app” and the “contents” of the control condition “setting flag” is “1” is “emergency notification application, not suppressed” as in the example of FIG. (YES in step G2, NO in step G3), it is determined that “do not suppress” (step G5). If the “contents” of the control condition “setting flag” is “1” is “emergency notification application, suppress” (YES in steps G2 and G3), it is determined to be “suppress” (step G4).

On the other hand, when “content” of the control condition “setting flag” is “1” is “emergency notification application, not suppressed”, “application other than emergency notification application, for example,“ TV playback application ”,“ video playback application ” "Is in operation (NO in steps G2 and G6), it is determined to be" suppressed "(step G4). If the" content "is" suppressed "(YES in step G6)," It is determined that “do not suppress” (step G5).

When such discrimination processing B (step E6 in FIG. 13) is completed, the central control unit 11 accesses the control condition storage unit M6, and its “ID” is “D03” (“item” is “operation mode”). The control condition is read (step E7), and it is checked whether the “setting flag” has “content” of “1” (step E8). If there is no “content” of “setting flag” of “1”, the next Move to Step E10. In the example of FIG. 6, since the “setting flag” of “emergency mode, not suppressed” is “1” as the “content” of the control condition (YES in step E8), it depends on the current operation mode. The process proceeds to a determination process C for determining whether or not to suppress the sound output to the sound speaker 23 (step E9).

FIG. 16 is a flowchart for explaining the discrimination process C (step E9 in FIG. 13) in detail. Since this determination process C is basically the same process as the above-described determination process A, a detailed description thereof will be omitted. First, the operation mode information storage unit M4 is accessed to read the operation mode information (step H1). The “content” of the operation mode whose “setting flag” is “1” is the control whose “setting flag” is “1”. It is checked whether or not the “content” of the condition is satisfied (step H2). Thereafter, the operation proceeds to the same operation as in the above-described discrimination process A. If the current operation mode is “emergency mode” and the “setting flag” is “1” and the “content” of the control condition is “emergency mode, not suppressed” (YES in step H2 and NO in H3), It is determined that “do not suppress” (step H5). Note that if the “content” of the control condition “setting flag” is “1” is “emergency mode, suppress” (YES in steps H2 and H3), it is determined to be “suppress” (step H4).

On the other hand, when the “contents” of the control condition “setting flag” is “1” is “emergency mode, not suppressed” and the operation mode is “radio wave off mode” (NO in steps H2 and H6), “ It is determined that “suppress” (step H4). If the “content” is “emergency mode, suppress” (YES in step H6), it is determined that “do not suppress” (step H5).

When such determination processing C (step E9 in FIG. 13) is completed, the central control unit 11 accesses the control condition storage unit M6, and its “ID” is “D04” (“item” is “ambient volume”). The control condition is read (step E10), and it is checked whether the “setting flag” has “content” of “1” (step E11). If there is no “content” of “setting flag” of “1”, the next The process proceeds to step E13. In the example of FIG. 6, since the “setting flag” of “less than *** dB, suppress” is “1” as the “content” of the control condition (YES in step E11), the current ambient sound volume Accordingly, the process proceeds to a determination process D for determining whether or not to suppress the sound output to the sound speaker 23 (step E12). Note that the ambient volume is “less than *** dB” means, for example, that a neighbor's voice can be heard clearly.

FIG. 17 is a flowchart for explaining the discrimination process D (step E12 in FIG. 13) in detail. Since this determination process D is basically the same process as the above-described determination process A, detailed description thereof will be omitted. First, after detecting the current ambient volume by the ambient volume detector 28 (step I1), it is checked whether this ambient volume satisfies the “content” of the control condition “setting flag” is “1” (step I2). . Thereafter, the operation proceeds to the same operation as in the above-described discrimination process A. If the current ambient volume is less than “*** dB”, the “content” of the control condition with the “setting flag” being “1” is less than “*** dB” as in the example of FIG. "(YES in steps I2 and I3), it is determined to be" suppressed "(step I4). If the “contents” of the control condition with the “setting flag” being “1” is less than “*** dB and not suppressed” (YES in step I2 and NO in step I3), it is determined as “not suppressed”. (Step I5).

On the other hand, when the “contents” of the control condition “setting flag” is “1” is “less than *** dB, suppress”, if the surrounding volume is “more than *** dB” (NO in step I2). , YES in step I6), it is determined that “do not suppress” (step I5), but if the “content” is “less than *** dB, do not suppress” (NO in step I6), “suppress” A determination is made (step I4).

When such determination processing D (step E12 in FIG. 13) is completed, the central control unit 11 accesses the control condition storage unit M6, and its “ID” is “D05” (“item” is “date and time”). The control condition is read (step E13), and it is checked whether or not there is “content” with “setting flag” “1” (step E14). If there is no “content” with “setting flag” “1”, the next Move on to step E16. In the example of FIG. 6, since the “setting flag” of “Sunday, do not suppress” is “1” as the “content” of the control condition (YES in step E14), the sound speaker 23 corresponds to the current date and time. Then, the process proceeds to a determination process E for determining whether or not to suppress the voice output for (step E15).

FIG. 18 is a flowchart for explaining the discrimination process E (step E15 in FIG. 13) in detail. Since this determination process E is basically the same process as the above-described determination process A, a detailed description thereof will be omitted. First, after acquiring the current date and time (including day of the week) from the RTC 21 (step J1), it is checked whether the current date and time satisfies the “content” of the control condition “setting flag” is “1” (step J2). Thereafter, the operation proceeds to the same operation as in the above-described discrimination process A. If the current date is “Sunday” and the “content” of the control condition “setting flag” is “1” is “Sunday, not suppressed” as in the example of FIG. 6 (YES in step J2) NO in step J3), it is determined that “do not suppress” (step J5). If the “content” of the control condition “setting flag” is “1” is “suppressed on Sunday” (YES in step J3), it is determined to be “suppressed” (step J4).

On the other hand, when the “content” of the control condition “set flag” is “1” is “Sunday, do not suppress” and the current date and time is “Monday” (NO in steps J2 and J6), “suppress” (Step J4), but if the current date and time is “Monday” and the “content” of the control condition is “Sunday, Suppress” (YES in Step J6), it is determined that “Do not suppress”. (Step J5).

When such determination processing E (step E15 in FIG. 13) is completed, the central control unit 11 accesses the control condition storage unit M6, and the “ID” is “D06” (“item” is “position”). The control condition is read (step E16), and it is checked whether or not there is “content” with “setting flag” “1” (step E17). 13 is completed. In the example of FIG. 6, since the “setting flag” of “position near home, not suppressed” is “1” as “content” of the control condition (YES in step E17), it depends on the current position. The process proceeds to a determination process F for determining whether or not to suppress the sound output to the sound speaker 23 (step K18).

FIG. 19 is a flowchart for explaining the discrimination process F (step E18 in FIG. 13) in detail. Since this determination process F is basically the same process as the above-described determination process A, detailed description thereof will be omitted. First, after acquiring the current position from the GPS receiver 16 (step K1), it is checked whether the current position satisfies the “content” of the control condition “setting flag” is “1” (step K2). Thereafter, the operation proceeds to the same operation as in the above-described discrimination process A. If the current position is “position near home” and the “content” of the control condition “setting flag” is “1” is “position near home, not suppressed” as in the example of FIG. (YES in step K2, NO in step K3), it is determined that “do not suppress” (step K5). If the “content” of the control condition “setting flag” is “1” is “position near home, suppress” (YES in step K3), it is determined as “suppress” (step K4).

On the other hand, when the “contents” of the control condition “set flag” is “1” is “position near home, not suppressed”, if the current position is “position away from home” (in steps K2 and K6). NO), “decrease” is determined (step K4), but if the current position is “position away from home” and the control condition “content” is “position near home, suppress” (NO in step K2, YES in step K6), it is determined that “do not suppress” (step K5).

As described above, when the headphone 10 is removed during the sound output to the headphone 10 and the above-described suppression determination process (step D24 in FIG. 12) is executed, it is checked whether it is determined as “suppressed” (FIG. 12). Step D25). Here, when it is determined to be “suppressed”, the content being reproduced is detected (step D26), and the emergency notification sound is being reproduced while the emergency notification application is operating (step D27). It is checked whether a broadcast / radio broadcast program is being reproduced or a recorded content is being reproduced (step D31).

If the emergency notification sound is being reproduced (YES in step D27), the sound output to the sound speaker 23 is suppressed, while the output of the sound (emergency notification sound) to the headphones 10 is stopped (step D28). Then, in order to indicate that the emergency notification sound has been stopped, the emergency notification sound stop flag is set to “1” and stored in the various information temporary storage unit M2 (step D29), and then the release timer described above is started (step D30). .

If the TV broadcast / radio broadcast program being received is being reproduced (YES in step D31), the audio output to the sound speaker 23 is suppressed, while the reception of the TV broadcast / radio broadcast program is stopped or recorded ( The recording operation for recording (recording) is started (step D32). If a television broadcast has been received, video output to the display unit 19 is stopped (step D33), and video output from the display unit 19 is stopped (step D34). Then, the audio output to the headphone 10 is stopped (step D35), and various information is temporarily stored by setting the TV broadcast / radio broadcast program stop flag to “1” to indicate that the TV broadcast / radio broadcast program is stopped. After storing in the part M2 (step D36), the above-described release timer is started (step D30).

If the recorded content is being reproduced (NO in step D31), the audio output to the sound speaker 23 is suppressed, while the reproduction of the content is temporarily stopped and the stop position is set to the operation mode information storage unit M4. (Step D37). If the content includes video, the video output is stopped for the display unit 19 (step D38), and the video output from the display unit 19 is stopped (step D39). Then, the sound output to the headphones 10 is stopped (step D40), and the temporary stop flag is set to “1” to indicate that the content reproduction is temporarily stopped, and then stored in the various information temporary storage unit M2 ( Step D41), the above-described release timer is started (Step D30).

On the other hand, as a result of executing the suppression determination process (step D24), if it is determined that “not to be suppressed” (NO in step D25), the sound output to the headphones 10 is stopped (step D42), and then the sound speaker. 23 starts sound output to the sound 23 (step D43), and starts sound output from the sound speaker 23 (step D44).

On the other hand, when the connection of the headphones 10 is detected (YES in step D1 in FIG. 11), it is checked whether sound is being output to the sound speaker 23 (step D2). Now, when the headphones 10 are connected during the sound output to the sound speaker 23 (YES in step D2), the sound output to the sound speaker 23 is stopped to switch the sound output destination (step D3), and the sound is output. After stopping the sound output from the speaker 23 (step D4), the sound output to the headphones 10 is started (step D5).

If connection of the headphones 10 is detected and sound is not being output to the sound speaker 23 (NO in step D2), the above-described release timer is operating, that is, the sound output to the sound speaker 23 is suppressed. A check is made (step D6). Here, if the release timer is not operating (not suppressed), the headphone process of FIGS. 11 and 12 ends, but if the release timer is operating and suppressed (in step D6). YES), a stop flag is read from the various information temporary storage unit M2 (step D7), whether or not the emergency notification sound stop flag is “1” (step D8), a television / radio broadcast program stop flag, a pause It is checked whether the flag is “1” (step D12).

If the emergency notification sound stop flag is “1” (YES in step D8), output of sound (emergency notification sound) to the headphones 10 is started (restarted) (step D9). That is, the emergency notification sound whose voice output has been stopped when the headphones 10 are removed is designated and the output is resumed. Then, after setting the emergency notification sound stop flag to “0” (step D10), the measurement operation of the release timer is stopped (step D11).

If the television broadcast / radio broadcast program stop flag is “1” (YES in step D12), reception of the television broadcast / radio broadcast program is started, or if the television broadcast / radio broadcast program is being recorded, the recording is performed. The contents are read (step D13). In the case of a television broadcast program, video output is started on the display unit 19 (step D14), video output from the display unit 19 is started (step D15), and audio is output to the headphones 10. (Step D16), the television broadcast / radio broadcast program stop flag is set to “0” (step D17), and the measurement operation of the release timer is stopped (step D11).

If the pause flag is “1” (NO in step D12), the stop position temporarily stored in the operation mode information storage unit M4 is read in order to continue playing the paused content. The reproduction of the content is resumed (step D18). If the content includes a video, video output is started on the display unit 19 (step D19), and video output from the display unit 19 is started (step D20). Then, sound output to the headphone 10 is started (step D21), the temporary stop flag is set to “0” (step D22), and the measurement operation of the release timer is stopped (step D11).

When the headphone process is executed in response to the headphone detection that the headphone 10 is connected or disconnected in this way (step A10 in FIG. 7), the sound speaker is determined based on whether or not the above control condition is satisfied. It is determined whether or not to suppress the audio output to 23, or when the headphones 10 are connected while the audio output to the sound speaker 23 is being suppressed, the suppression is released.

Next, the release process described above (step A12 in FIG. 7) will be described in detail according to the flowchart in FIG. First, after executing the above-described suppression determination process (FIGS. 13 to 19) (step L1 in FIG. 20), the central control unit 11 checks whether it is determined as “suppressed” based on the determination result (step S1). L2) When it is determined that “suppress”, a release timer is started (step L3). In other words, when it is determined that “suppression” is obtained in the suppression determination process after the timeout detection of the release timer, the suppression of the sound output to the sound speaker 23 is continued, and the next timing for releasing the suppression is measured. The release timer is started for this purpose.

As a result of the suppression determination process, when it is determined that “not suppressed” (NO in step L2), a stop flag is read from the various information temporary storage unit M2 (step L4), and the emergency notification sound stop flag is “1”. Is checked (step L5), and whether the television broadcast / radio broadcast program stop flag and the pause flag are “1” is checked (step L10). If the emergency notification sound stop flag is “1” (YES in step L5), output of sound (emergency notification sound) to the sound speaker 23 is started (step L6), and the sound from the sound speaker 23 is output. The output of (emergency notification sound) is started (step L7). Then, after setting the emergency notification sound stop flag to “0” (step L8), the measurement operation of the release timer is stopped (step L9).

If the television broadcast / radio broadcast program stop flag is “1” (YES in step L10), reception of the television broadcast / radio broadcast program is started (step L11). When a television broadcast is received, video output is started on the display unit 19 (step L12), video output from the display unit 19 is started (step L13), and the sound speaker 23 is started. Audio output is started (step L14), and audio output from the sound speaker 23 is started (step L15). Then, after setting the television broadcast / radio broadcast program stop flag to “0” (step L16), the measurement operation of the release timer is stopped (step L9).

If the pause flag is “1” (NO in step L10), the reproduction of the content is resumed in order to continue the reproduction of the paused content (step L17). If the content includes video, video output is started to the display unit 19 (step L18), video output from the display unit 19 is started (step L19), and the sound speaker 23 is started. Audio output is started (step L20), and audio output from the sound speaker 23 is started (step L21). Then, after setting the temporary stop flag to “0” (step L22), the measurement operation of the release timer is stopped (step L9).

As described above, in this embodiment, the central control unit 11 determines whether or not the control condition is satisfied when it is detected that the connection with the headphone 10 is disconnected during the sound output to the headphone 10. Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on the result, the control can be appropriately performed according to the situation. In this case, if the situation is not suitable for outputting sound to the sound speaker 23, the output of the sound is suppressed, and if the situation is appropriate, the output of the sound is not suppressed. Convenience can be ensured.

When the audio output to the sound speaker 23 is suppressed, the reproduction of the content is stopped. Therefore, it is possible to save power by suppressing the power consumed for reproducing the content. In addition, when the stop is paused, if the user resumes the reproduction of the content, the continuation can be easily viewed, and the convenience is further improved. For example, even if the headphone 10 is disconnected and the output of sound to the sound speaker 23 is mistakenly suppressed while the headphone 10 is connected to the mobile phone 1 and playing music content, the user reconnects the headphone 10. It is possible to easily reproduce the continuation of the music content.

In a state where the sound output to the sound speaker 23 is being suppressed, if the situation is suitable for the sound output to the sound speaker 23, the suppression of the sound output is canceled, so that convenience for the user is ensured. Can do.

Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on whether or not the predetermined transportation is being used, if the transportation is not suitable for the sound output to the sound speaker 23, If it is a suitable transportation means that suppresses the output of sound, it is possible to prevent the output of the sound from being suppressed, and it is possible to prevent inconvenience to the surroundings and ensure convenience for the user. For example, in the case of highly public transportation such as trains, buses, and airplanes, it is possible to prevent disturbance to the surroundings by suppressing the output of sound, and for personal transportation such as private cars, By preventing the output from being suppressed, convenience for the user can be ensured.

Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on whether or not the predetermined application program is operating, if the application program is not suitable for the sound output to the sound speaker 23, the sound If it is a suitable application program, it is possible to prevent the output of the voice from being suppressed, so as to prevent inconvenience to the surroundings and to ensure convenience for the user. For example, in the case of an application program with high entertainment such as an application program for music playback and an application program for TV program playback, it is possible to prevent annoyance to the surroundings by suppressing the output of sound and to notify that it is an emergency state. If it is a highly urgent application program, convenience for the user can be ensured by not suppressing the output of audio.

Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on whether or not the predetermined operation mode is set, if the operation mode is not suitable for the sound output to the sound speaker 23, It is possible to suppress the output of the sound and not to suppress the output of the sound if it is in a suitable operation mode, so that it is possible to prevent inconvenience to the surroundings and ensure convenience for the user. For example, if the operation mode has a high possibility of being in a public place such as radio wave off mode, it is possible to prevent annoyance to the surroundings by suppressing the output of sound and to be a highly urgent operation mode such as emergency mode. For example, convenience for the user can be ensured by not suppressing the output of the voice.

Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on whether or not the surrounding sound volume satisfies a predetermined sound volume condition, the surrounding sound volume is not suitable for the sound output to the sound speaker 23. If there is, the output of the sound can be suppressed, and if the surrounding volume is suitable, the output of the sound can be prevented from being suppressed, so that trouble to the surroundings can be prevented and convenience for the user can be ensured. For example, if the surrounding volume is low, that is, if the surroundings are quiet, annoying the surroundings is prevented by suppressing the output of the sound, and if the surrounding volume is high, that is, if the surroundings is noisy, the output of the sound is suppressed. By not doing so, it is possible to ensure convenience for the user.

Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on whether or not the current time satisfies a predetermined time condition, if the time is not suitable for the sound output to the sound speaker 23, By suppressing the audio output and not suppressing the audio output at a suitable time, it is possible to prevent inconvenience to the surroundings and to ensure convenience for the user. For example, in the early morning, late at night, commuting / commuting time zone, by preventing the inconvenience to the surroundings by suppressing the output of the sound, and by suppressing the output of the sound during the daytime or holiday, Convenience for the user can be ensured.

Since whether or not to suppress the sound output to the sound speaker 23 is controlled based on whether or not the position information indicating the position of the mobile phone 1 satisfies a predetermined position condition, the sound output to the sound speaker 23 is controlled. If the position is not suitable, the output of the sound can be suppressed, and if the position is appropriate, the output of the sound can be prevented from being suppressed, and it is possible to prevent inconvenience to the surroundings and ensure convenience for the user. it can. For example, if it is in a public facility, it suppresses the output of the sound to prevent inconvenience to the surroundings, and if it is at home or outdoors, it does not suppress the output of the sound, thereby improving the convenience for the user. Can be secured.

In the above-described embodiment, the headphone is exemplified as the external sound output device. However, the present invention is not limited to this. For example, any external sound output device that can output sound input from the terminal device, such as an earphone. It may be. The terminal device is not limited to a mobile phone, and may be any terminal device that reproduces content, such as a personal computer, a PDA (personal personal digital assistant), a digital camera, or a music player.
Furthermore, the content is not limited to an emergency notification sound, a television program, a radio program, music, and a moving image, and may be any content including sound such as an electronic book having a speech reading function.

In the above-described embodiment, a plurality of control conditions are stored in the control condition storage unit M6 and any one of the control conditions is used. However, only one control condition is used more simply. Alternatively, the contents of the control condition may not be set by the user.
Further, the “item” of the control condition is not limited to a predetermined transportation, application, operation mode, ambient volume, date / time, and position, but may be any transportation, application, operation mode, ambient volume, date / time, and position. .
