  Further, the current position recognizing means 181 judges the inclination and height difference of the road on the basis of the acceleration data output from the acceleration sensor, calculates the current pseudo position of the vehicle, and recognizes the current position. That is, it is possible to accurately recognize the current position of the vehicle even at places that overlap on a plane such as a three-dimensional intersection or an expressway. In addition, when traveling on mountain roads and hills, the current distance is obtained by correcting the error between the travel distance obtained from speed data and azimuth angle data and the actual vehicle travel distance using the detected road slope.

The display control unit 183 also controls display of various display screens for setting and inputting various information by prompting an input operation by the input unit 130, for example.

  The route processing unit 184 determines the travel route that is the vehicle travel route based on the setting item information for the travel route search process that is set and input by the user and the map information stored in the storage unit 160. Calculate route search. Specifically, the route processing means 184 uses the map information based on the setting item information that has been set and input, for example, searches for a road on which the vehicle can pass, and the time required to travel until reaching the destination. Movement route information such as a short route or a route with a short movement distance is generated. When generating the travel route information, the route processing unit 184 appropriately obtains VICS data from the VICS output from the VICS receiving unit 120, for example, and generates traffic jam information that is predicted to occur at present or after a predetermined time. A route that avoids traffic jams or traffic restrictions may be set using the traffic jam information. Further, the route processing unit 184 obtains a predicted required time for the movement from the current position, which is the departure point in each route of the moving route information, to the destination, and can also generate the required time information regarding the predicted required time. . The obtained travel route information is appropriately stored in the memory 170 together with traffic jam information, required time information, and the like.

Get information according to the search request. The acquired search result information is appropriately stored in the memory 170.

  The time measuring means 186 recognizes the current time based on a reference pulse such as an internal clock. And this time measuring means 186 outputs the time information regarding the recognized current time as appropriate.

  The dialogue position detecting means 187 determines the position of the seat, which is a dialogue position for carrying out dialogue operations such as a dialogue operation in which a driver or a passenger interacts using a mobile communication device or a dialogue operation in which a window is opened and dialogues with the outside. To detect. As the detection of the dialogue position, for example, a pseudo coordinate value based on a navigation radio wave received by, for example, a GPS receiver as a current position recognition unit provided in the mobile communication device can be obtained from the mobile communication device by a wireless medium, or mobile communication can be performed. For example, the device is acquired through a signal line connected to the navigation device. In addition, for example, a mobile phone number used by a driver or a passenger is set and input in advance by the input unit 130 together with the seat position, and the mobile phone is based on a connection request for a call or a radio wave at the time of the call. The number may be specified and the seat position may be detected as the dialogue position. Further, a seat adjacent to the window when the window is opened based on the replacement information stored in the memory 170 may be detected as the conversation position. Then, the dialog position detection unit 187 appropriately outputs a dialog position signal related to the dialog position detected as described above to the sound generation control unit 191.

  When the stop state detection unit 188 recognizes that the vehicle is stopped based on the event signal output from the sensor unit 110, the current position recognized by the current position recognition unit 181 opens a window and interacts with the outside. Determine whether it is adjacent to the facility that needs to be done. As a method of detecting the adjacent state with the facility that needs to interact, whether it is adjacent to the drive-through facility in the toll road toll booth or gas station, so-called drive-through facility based on the map information. Furthermore, it can be exemplified that a predetermined signal output from a toll gate, a gas station refueling device, or a drive-through facility is received to recognize that it is adjacent to a facility that requires dialogue. When the stop state detection unit 188 determines that it is adjacent to a facility that needs to open a window and interact with the outside, the stop state detection unit 188 appropriately outputs a confirmation signal to the sound generation control unit 191.

  The MIDI sound source generation means 190 includes sound information compliant with the MIDI standard, for example, the GM (General MIDI) standard standardized by the US MMA (MIDI Manufacturers Association) and the Japan MIDI Standards Committee (JMSC), Alternatively, a MIDI message based on the GS (General Standard) standard, the XG (Extended General MIDI) standard, or the GM level 2 standard is generated. The MIDI sound source generation means 200 generates and outputs sound information directly based on a signal requesting output of sound information, for example, or acquires and outputs sound information separately stored in the memory 170 or the like. . In addition, as sound information to be notified, for example, in addition to an alarm sound to call attention when outputting voice at the time of guidance for movement, the remaining amount of fuel, the engine temperature, the distance to other vehicles ahead, Alternatively, in order to notify the situation of the vehicle for movement such as the distance to the obstacle behind the vehicle as an event, sound information that has a different tone color or pattern is set in advance for each event content.

  The sound generation control unit 191 recognizes the movement status based on the current position recognized by the current position recognition unit 181 and the map information, and based on the feature route information or the feature guide information on the features constituting the map information. Then, guidance regarding the movement of the vehicle, for example, the content for supporting the traveling of the vehicle is notified by the sound generation by the sound generation means 150. Specifically, after sounding the alarm sound as sound information with the sound generation means 150, “700m ahead, the XX intersection is rightward in the direction of △△”, “Departed from the moving route.” The voice data as the sound information stored in advance in the storage means 160, the memory 170, or the like is output as voice. Further, the sound generation control means 191 includes an event signal relating to the remaining amount of fuel, an event signal relating to the engine temperature, an event signal relating to the distance from the vehicle traveling ahead, and an obstacle in the rear as the vehicle movement status output from the sensor unit 110. Acquire event signals related to the distance to objects and recognize the movement status. Then, based on the acquired event signal, the sound generation unit 150 generates an alarm sound according to the state of the event that has occurred. In this pronunciation, for example, there are different tones and patterns depending on the content to be notified, such as the remaining amount of fuel, the engine temperature, the distance to the vehicle in front, the distance to the obstacle behind the vehicle, the alarm sound at the guidance guidance, etc. Control is performed to output sound information from the MIDI sound source generation means 190.

  When the sound generation control unit 191 recognizes the dialogue detection signal in the event signal from the sensor unit 110, the tone generation control unit 191 is based on the dialogue position signal output from the dialogue position detection unit 187 and the confirmation signal output from the stop state detection unit 188. The position of the sound image localization by sound generation, which is the output of sound information from the speaker, is controlled so as to be away from the dialogue position. Specifically, for example, when it is recognized that the driver is in a state of dialogue, the sound image localization for the driver up to that time, such as the left and right direction or the front and rear direction from the driver, and the opposite side of the diagonal line, the up and down direction, etc. The position is controlled to be relatively far from the driver.

  As a control for moving the sound image localization, specifically, when an alarm sound to be generated immediately before outputting a voice at the time of guidance guidance is a MIDI message, a process for changing a parameter value constituting the MIDI message is performed. Thus, the sound image localization can be moved in the left-right direction with respect to the traveling direction of the vehicle, or the sound image localization can be moved in the front-rear direction by combining control by a digital signal processor (DSP). As a change in the parameter value of the MIDI message, for example, as shown in FIG. 3, the parameter of the panpot of the lower layer control change in the channel voice message constituting the table structure of the MIDI message, that is, the address The value of the format dM in cc # 10 is set as appropriate. This parameter value is a sound image localization value that has been a value in the vicinity of “90” in front of the driver until then (near “30” when the vehicle is a right-hand drive vehicle and a left-hand drive vehicle). The value is changed to a value close to “0”, which is a position close to the left side of the vehicle, or a value close to “127”, which is a position close to the right side. Here, since the driver's seat is located on the right side of the approximate center of the vehicle (the left side when the vehicle is a left-hand drive vehicle), the format dM value is “90” on the right side of the value “64” that is approximately the center. "(Near" 30 "on the left side of a left-hand drive vehicle)". In this way, it may be controlled so as to be relatively distant from the driver and the passenger who interact with each other. The configuration in which the parameter value is set in a state where the sound image localization moves in the left-right direction will be described. May be.

(Operation of navigation device)
Next, the operation of the navigation device 100 will be described with reference to the drawings. FIG. 4 is a flowchart showing a travel route search process in the navigation device 100. FIG. 5 is a flowchart showing a process of moving the sound image localization.

  First, a passenger who is a user who has boarded the vehicle turns on the power of the navigation device 100 and supplies power. With this power supply, the processing unit 180 controls the display unit 140 to display the main menu, and causes the display unit 140 to display a display screen that prompts the user to input a setting for the content to be operated by the navigation device 100.

  Then, the user performs a setting input for performing, for example, a search process of a moving route for moving by an input operation of the input unit 130 based on the display screen (step S101). By this setting input, the processing unit 180 displays a display screen that prompts the user to input setting information such as various information necessary for the search for the moving route, for example, the destination, the shortest distance, the shortest time, or the traffic information. The information is displayed on the display means 140 by the control means 183. Then, when the route processing unit 184 recognizes various types of information necessary for the travel route search, the processing unit 180 first performs a process of recognizing the current position by the current position recognition unit 181 (step S102), and the destination recognition unit. A process of recognizing the destination set and input at 182 is performed (step S103).

  Specifically, the current position recognizing means 181 converts the vehicle speed data and azimuth angle data output from the speed sensor and azimuth angle sensor of the sensor unit 110 and the GPS data relating to the current position output from the GPS receiver unit. Based on this, the current position of the vehicle is calculated to obtain the current position information. The acquired current position information is appropriately stored in the memory 170. Further, the processing unit 180 controls the display unit 140 with the display control unit 183 to display a display prompting the user to input a destination setting by an input operation of the input unit 130. When the user sets and inputs a destination by an input operation of the input unit 130 in accordance with an instruction on the displayed display screen, the destination recognizing unit 182 acquires destination information related to the set and input destination. The acquired destination information is appropriately stored in the memory 170. In the destination input operation, the information search means 185 searches for search information related to the destination using, for example, map information, or moves the cursor to the destination on the map information displayed on the screen and specifies it. Any method can be used.

  Further, the processing unit 180 controls the display unit 140 by the display control unit 183 to display a display prompting an input operation of a setting item that is a condition for searching for a moving route. Then, when the user sets and inputs the setting items by the input operation of the input unit 130 according to the instruction on the displayed display screen, the processing unit 180 acquires the setting item information regarding the setting items that have been set and input (step S104). The acquired setting item information is stored in the memory 170 as appropriate.

  Thereafter, the processing unit 180 acquires the setting item information stored in the memory 170 by the route processing unit 184, and also appropriately acquires the VICS data output from the VICS receiving unit 120, from the current position of the vehicle to the destination. A route search process for searching for the movement route is performed based on the map information stored in the storage means 160 (step S105). In this route search processing, the route processing means 184 acquires a plurality of movement routes by calculation, and narrows down to several based on setting item information and traffic information acquired as appropriate. Then, the display control unit 183 displays, for example, five calculated travel routes on the display unit 140 and displays a request for selection by the user. Then, the movement route is set by an input operation in which the user selects one of the movement routes according to the display. Here, when the calculation result has only one route, the display requesting the selection is not displayed, and that one route is set as the movement route. The configuration is not limited to selecting from a plurality of travel routes, but may be a configuration in which only one travel route that best meets the conditions of the setting item information is displayed to allow the user to confirm.

  And the process part 180 controls the display means 140 by the display control means 183, displays the map information memorize | stored in the memory | storage means 160 suitably, and performs a guidance guidance process (step S106). In this guidance and guidance process, the processing unit 180 superimposes and displays on the map information, for example, a display relating to the moving route together with an icon representing the current position of the vehicle, and a display relating to traffic information such as traffic jam information.

  Thereafter, the processing unit 180 recognizes the moving state of the vehicle based on the signals output from the speed sensor, the azimuth angle sensor, and the acceleration sensor of the sensor unit 110 and the GPS data output from the GPS receiving unit. Further, the processing unit 180 uses the display unit 140 to display guidance information related to vehicle movement based on the movement status recognized by the display control unit 183 and the sound generation control unit 191 and the route guidance information included in the movement route information. The display or the sound generation means 150 generates a sound or an alarm sound to notify the user and guides the movement of the vehicle.

  At the time of this guidance, for example, when the driver stops at a gas station, the processing unit 180 is stored in the storage unit 160 by the information search unit 185 in response to a search request for search information set and input by the input unit 130, for example. Based on the search information of the map information, for example, a store or facility is searched for the nearest gas station based on the search condition from the item information and the information is acquired. Then, the processing unit 180 causes the display control unit 183 to display the display unit 140 by superimposing it on the map information based on the acquired information about the gas station. When requesting the setting of the travel route to the gas station at the time of this search, the travel route to the gas station searched by the route processing means 184 is searched and superimposed on the map information by the control by the display control means 183. Display.

  And if a vehicle moves to a gas station and stops, the sensor part 110 will recognize that the vehicle stopped based on the detection signal from a sensor, and will output an event signal. Based on the output of the event signal indicating that the vehicle has stopped, the stop state detection means 188 opens the window using the map information based on the current position information related to the current position recognized by the current position recognition means 181 and externally. Judge as the gas station of the facility that needs to talk to. Then, the stop state detection unit 188 outputs a confirmation signal to the sound generation control unit 191.

  When the driver controls the sound generation control unit 191 to recognize the confirmation signal and opens the window to interact with the store clerk, the sensor unit 110 recognizes that the window is opened based on the detection signal from the sensor. Then, a dialogue detection signal is output (step S201). By outputting the dialogue detection signal, the dialogue position detection means 187 recognizes the seat position adjacent to the opened window based on the replacement information stored in the memory 170, for example, and detects the seat position as the dialogue position. . Then, the dialogue position detection unit 187 outputs a dialogue position signal related to the dialogue position to the sound generation control unit 191 (step S202).

  Then, when the sound generation control means 191 recognizes the dialogue detection signal, based on the confirmation signal, the sound generation control means 191 determines that the opened window is not for mere ventilation or the like but for dialogue, and from the current speaker, music information and TV audio data, It is determined whether or not sound information such as voice data for guidance and guidance, an alarm sound, and an alarm sound for informing the refueling situation is output, ie, sounded (step S203). If it is determined in step S203 that no sound is produced from the speaker or there is no sound information to be produced, this processing is terminated.

  If it is determined in step S203 that sound information is being output or sound information is to be output, the sound message localization with respect to the driver's seat at the dialog position is distant based on the dialog position signal. Processing to change the parameters as appropriate is performed (step S204). Then, the sound generation means 150 is controlled based on the set MIDI message, and the sound generation state of the sound information from each speaker is changed to generate sound. This places the sound image localization farther from the driver, making it easier for the driver to interact with the gas station clerk. The set value before the change of the pararotor is separately stored in the memory 170 or the like.

  After this, for example, the sound generation control means 191 has a dialogue based on an event signal output from the sensor unit 110 indicating that refueling has ended, an event signal indicating that the window has been closed, an event signal indicating that the vehicle has moved, and the like. It is determined that the processing has ended (step S205). Then, the sound generation control unit 191 changes the parameter setting value based on the parameter setting value before the change stored in the memory 170, and again controls the sound image localization to be the original position (step S206). Ends. As a result, the original sounding state is automatically obtained without the driver's operation, and convenience is improved.

  On the other hand, the sensor unit 110 uses a mobile phone when guiding the user, when the passenger talks using a mobile phone that is a mobile communication device, or when there is a connection request from the outside to the passenger's mobile phone. The dialogue detection signal is output based on the detection signal from the sensor that detects the radio wave at the time of the conversation or when the connection is requested. The dialogue position detection unit 187 detects the dialogue position indicating which seat the cellular phone is used on, based on the dialogue detection signal from the sensor unit 110. As described above, as the detection of the dialog position, when the radio wave is detected by the sensor, the current position recognition means based on a GPS receiving unit (not shown) mounted on the mobile phone is used. The information on the terminal current position is acquired by the sensor unit 110 and is recognized by outputting it to the dialog position detecting means 187 together with the dialog detection signal. In addition, various methods can be used such as obtaining replacement information related to the seat position set in advance when boarding from the memory 170 and specifying the seat position in comparison with the characteristics of radio waves. Then, the dialogue position detection unit 187 outputs a dialogue position signal related to the dialogue position, which is a seat where the mobile phone is used, to the sound generation control unit 191.

  Then, the sound generation control means 191 recognizes the dialogue due to the use of the mobile phone based on the dialogue detection signal and processes it in the same manner as described above. That is, when sound information such as music information or TV sound data is produced from the speaker, the parameter relating to the panpot of the MIDI message is set to a state where the sound image localization is separated from the seat using the mobile phone based on the dialogue position detection signal. Then, the sound generation unit 150 is controlled to change the sound generation state. As a result, the passenger can interact well with the mobile phone without being disturbed by the pronunciation from the speaker. Then, when the sound generation control unit 191 recognizes a signal indicating that the mobile phone call is ended from the sensor unit 110, the sound image position is similarly returned to the original position.

(Operational effect of navigation device)
As described above, in the above embodiment, the sensor unit 110 detects a dialogue operation by a mobile phone or the like and an operation such as opening a window for dialogue, and outputs a dialogue detection signal. When a dialogue position serving as a seat position where the operation is performed is detected and a dialogue position signal is output, the sound generation control unit 191 controls the sound generation unit 150 so that the sound image localization is away from the dialogue position, thereby changing the sound generation state from the speaker. Control. For this reason, the sound image localization is automatically separated at the dialogue position, and it can be heard as if the volume is lowered, the air vibrations other than the dialogue are reduced, the air vibrations caused by the dialogue are not hindered, and the input unit 130 is operated. It is possible to continue to listen to the sound without being heard by other passengers who are not involved in the conversation as in the case of simply automatically muting as in the past. . Furthermore, since the sound image localization automatically moves, it is not necessary to operate the input means 130 to move the sound image localization every time a dialogue is performed, and usability can be improved.

  Then, when it is recognized that the dialogue has been completed, the process of returning to the original sound image localization is performed again. For this reason, it is not necessary to operate the input unit 130 to restore the sound image localization, and the usability can be further improved.

  Moreover, the opening of the window of the vehicle is detected as the detection of the dialogue operation or the operation for dialogue. For this reason, for example, a dialogue operation and an operation for dialogue can be obtained with a simple configuration such as using a switch for detecting opening of a window.

  Further, the vicinity of the opened window is detected as the dialogue position. For this reason, since the sound image localization is in a state of being separated from the vicinity of the window, a good dialogue through the window can be obtained without being disturbed by the pronunciation.

  And it is set as the movement of the sound image localization in the room | chamber interior in a vehicle. For this reason, the dialog position can be specified easily, for example, the seat position adjacent to the opened window, the calculation process can be easily performed, the configuration can be simplified, and the processing speed can be increased. Is easily obtained.

  Further, as the vicinity of the window, the seat position of the vehicle adjacent to the opened window is used. For this reason, for example, replacement information with a small amount of information in a simple data structure in which a window and a seat position are associated with each other can be used, and the configuration can be simplified and the processing speed can be easily increased.

  Further, the sound generation control means 191 that recognizes the dialogue detection signal such as opening of the window interacts based on the map information between the event signal from the sensor unit 110 indicating that the vehicle has stopped and the current position recognized by the current position recognition means. The sound image localization is controlled by recognizing a confirmation signal from the stop state detection means 188 that the position is adjacent to a toll gate, a gas station, a drive-through facility, or the like. For this reason, for example, it is determined that the window is not a window for simply ventilation but a window for dialogue, and control for moving the sound image localization appropriately without malfunction is performed, improving usability.

  As control for moving the sound image localization, the parameter of the MIDI message, which is sound information compliant with the MIDI standard, is changed to a state away from the dialogue position detected by the sound image localization. For this reason, since a MIDI message with a simple configuration and a small amount of information is used, the processing load can be reduced, the configuration can be easily simplified, and the processing speed can be easily increased.

  Further, a parameter value that is a setting value of panpot information is appropriately set as a parameter of the MIDI message. For this reason, simple processing for simply setting parameter values with a small amount of information can be obtained, control for moving the sound image localization can be easily performed with simple control, the processing load can be reduced, and the configuration can be easily simplified and processed. Can be easily achieved.

  And it is used for sound image localization movement control in a navigation device such as notification by pronunciation of guidance guidance for good operation of the vehicle, notification of the state of the vehicle, and outputting music information for comfortable operation. For this reason, a good notification can be obtained in normal times, and a good dialogue can be obtained by sound image localization during dialogue, and the sound image localization can be moved without being muted. A state etc. are alert | reported appropriately and favorable movement of a vehicle is obtained.

  In addition, as detection of an interactive operation and an operation for the interactive operation, radio waves such as a call by a mobile communication device such as a mobile phone and a connection request for the call are detected. For this reason, it is possible to easily detect the dialogue operation and the operation for the dialogue, and appropriately perform the process of moving the sound image localization for a good dialogue. Further, in the case of a dialogue detection signal based on a dialogue operation using a mobile communication device or a dialogue operation, the sound generation control unit 191 performs sound image localization without performing a process of confirming the dialogue operation based on the confirmation signal. It is controlled to move. For this reason, the processing speed can be increased and a good dialogue can be obtained.

  Then, as a dialogue position detection when a dialogue operation by a mobile communication device such as a mobile phone or an action for dialogue is recognized, the dialogue position can be easily detected by using a radio wave which is a wireless medium used in the mobile communication device. Can be detected. Furthermore, the terminal current position information from the current position recognition means provided in the mobile communication device is acquired to recognize the dialog position. For this reason, the processing load for recognizing the dialogue position can be reduced, and the simplification of the configuration and the speeding up of the processing can be easily obtained.

  Further, if the sound information is not output from the speaker even if the dialogue operation or the dialogue operation is detected, the processing is terminated. For this reason, the processing load can be reduced, and the processing load can be used for other control and processing such as searching for a moving route, and the speed of other processing can be increased, and a good navigation apparatus can be obtained.

  Further, by moving the sound image localization to the opposite side on the diagonal line, a more distant state can be obtained, a better dialogue environment can be obtained, and a good dialogue can be obtained.

  Furthermore, by moving the sound image to a position that is substantially point-symmetric with respect to the center of the vehicle as a movement of the sound image, it is possible to obtain a state that is relatively far from the dialogue position, and as a state of sound that other passengers listen to Good listening is obtained without changing greatly.

  Since the processing unit 180 is configured as a program using, for example, a CPU (Central Processing Unit) or the like, by installing the program, a configuration capable of controlling the modulation of sound can be easily obtained, and the use can be easily expanded. I can plan. Furthermore, by recording the program on a recording medium and appropriately allowing the computer to read the program, a configuration capable of easily controlling the modulation of sound can be obtained, and the program can be easily handled and used. Can be easily expanded. The calculation means in the present invention is not limited to a single computer, but may include a configuration in which a plurality of computers are combined in a network, an element such as a CPU and a microcomputer, or a circuit board on which a plurality of electronic components are mounted. Including.

[Second Embodiment]
Next, a second embodiment according to the present invention will be described with reference to the drawings. In the second embodiment, instead of the configuration in which the sound image localization in the first embodiment is controlled to be away from the dialogue position, the control is performed to reduce only the sound pressure level near the dialogue position. Is. FIG. 6 is a block diagram showing a schematic configuration of the navigation system in the second embodiment. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted or simplified.

  As shown in FIG. 6, the processing unit 180 of the navigation device 100 includes a destination recognition unit 182 as a destination information acquisition unit, a display control unit 183, a route processing unit 184, an information search unit 185, and a time measuring unit. 186, dialogue position detection means 187, stop state detection means 188, inverted sound information generation means 189, MIDI (Musical Instrument Digital Interface) sound source generation means 190, sound generation control means 191 and the like.

  The inverted sound information generation unit 189 reads the sound information sequentially stored in the memory 170 and calculates an inverted sound having an opposite phase to the sound information. Then, the inverted sound information generating unit 189 appropriately outputs the inverted sound information regarding the calculated inverted sound to the memory 170 and sequentially stores it. Note that the reverse sound information is stored in the memory 170 in synchronization with the sound information that is sequentially stored. Then, when the sound information is output from the memory 170 and sounded from the speaker, the sound information is sequentially deleted from the memory 170. Furthermore, for example, a reversed sound having a polarity reversed with respect to sound information may be generated by using a circuit including a switching element or the like. Note that the present invention is not limited to these methods.

  As in the first embodiment, the sound generation control means 191 recognizes the movement status based on the current position recognized by the current position recognition means 181 and the map information, and forms the route information and map information. Based on the feature guidance information on the object, etc., the guidance on the movement of the vehicle is notified by the pronunciation by the sound generation means 150. When the sound generation control unit 191 recognizes the dialogue detection signal in the event signal from the sensor unit 110, the tone generation control unit 191 is based on the dialogue position signal output from the dialogue position detection unit 187 and the confirmation signal output from the stop state detection unit 188. Control is performed to reduce only the sound pressure level in the vicinity of the dialogue position. Specifically, for example, when it is recognized that the driver is in a state of dialogue, only the driver can reduce the sound pressure level, and other passengers cannot recognize that the sound pressure level has decreased so much. Reduce only nearby sound pressure levels. As a method for reducing the sound pressure level in the predetermined area, for example, using a directional speaker, the above-described inverted sound information is output with directivity limited to the vicinity of the detected dialogue position, and the sound information output from the speaker is output. To cancel the sound pressure level in the vicinity of the dialogue position, or to control the sound pressure level to be substantially “0”, or use the speaker mounted on the vehicle as a directional speaker, For example, control of outputting sound information with directivity that can be heard can be given.

  In the second embodiment, as in the sound generation control in the first embodiment, when a dialogue operation or a dialogue operation is detected, a confirmation signal is appropriately confirmed to specify the dialogue position. . Then, the sound generation control means 191 controls so that only the sound pressure level near the dialogue position is reduced.

  In the second embodiment, as in the first embodiment, the sound pressure level is automatically reduced at the dialogue position, and a good dialogue can be obtained without operating the input means 130. Thus, other passengers who are not involved in the dialogue as in the case of automatically performing the mute process can continue to listen without losing the pronunciation from the speaker. Furthermore, since the sound image localization is automatically moved, it is not necessary to move the sound image localization by operating the input means 130 each time a dialogue is performed, and the operational effect of improving usability can be obtained.

  In addition, as a configuration for reducing only the sound pressure level in the vicinity of the dialogue position, sound information generated from the speaker is output while being sequentially stored in the memory 170 or the like, and an inverted sound having an opposite phase to the stored sound information is generated. And synchronously store them in the memory 170 or the like. Then, in the process of reducing the sound pressure level, sound is generated with directivity that outputs the inverted sound only in the area near the detected dialogue position. With this configuration, it is possible to talk well at the dialogue position, and there is almost no change in the characteristics of the sound being produced at the positions of other passengers, so that particularly good viewing can be achieved. Then, by using the configuration in which the sound to be generated is sequentially stored using the memory 170 as a buffer, it is possible to secure time for generating the inverted sound, and the inverted sound is already generated in the process of reducing the sound pressure level. Since it is generated, it is possible to quickly reduce the sound pressure level.

  In addition, as a configuration that reduces only the sound pressure level in the vicinity of the dialogue position, by using a directional speaker to control the area where the sound is generated to a directivity other than in the vicinity of the dialogue position, Good sound can be viewed without changing the characteristics of the sound being pronounced.

[Modification of Embodiment]
In addition, this invention is not limited to each embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.

  That is, as described above, the configuration of the navigation device 100 that guides and guides the movement of the vehicle has been described. However, as described above, the navigation device 100 may be used for an apparatus such as an audio device or a TV. Furthermore, as a form for processing the movement of the sound image localization and the reduction of the sound pressure level described above, not only the vehicle but also a building such as a house as a structure can be targeted. For example, when music information or TV audio data is output indoors, if the mobile phone is used indoors, the mobile phone is moved away from the location where the mobile phone is used, or near the area. Only the sound pressure level may be reduced. Further, as the detection of the dialogue, when the window of the room is opened, the use of the telephone may be detected by a sensor or a line state. In the case of a fixed telephone, a method of storing the position where the telephone is installed in advance as replacement information in the memory 170 or the like can be used. Furthermore, voice data from dialogue is collected with a microphone, etc., and the voice data is processed to remove noise, etc., and it is determined whether there is a real voice, and the dialogue operation is detected, or imaging is performed with an imaging device. Any method can be used, such as processing the processed image data to recognize a person, and processing the person's mouth and actions to detect a dialogue action. Furthermore, human detection sensors and thermal sensors that use laser light and infrared rays are appropriately arranged in the space, and these sensors detect the position of a person and detect dialogue at that position. Applicable. Moreover, it can utilize as not only a navigation apparatus but a sound apparatus for vehicle-mounted use.

  The moving body is not limited to a vehicle, and can be applied to any moving body such as an airplane or a ship. The moving body may be a user who carries the terminal device. Furthermore, as described above, a configuration in which the user directly carries the device, or a configuration in which the mobile phone or PHS (Personal Handyphone System) is used as a terminal device, or a communication method that appropriately detects the movement status using the network is used. It can also be applied to configurations. Here, as the network, for example, the Internet based on a general-purpose protocol such as TCP / IP, an intranet, a LAN (Local Area Network), a communication line network in which a plurality of base stations capable of transmitting and receiving information via a wireless medium constitute a network, Examples include a network such as a broadcast network, and a wireless medium itself such as radio waves, light, sound waves, and electromagnetic waves, which are media for directly transmitting and receiving information.

  Furthermore, although each function mentioned above was constructed | assembled as a program, as above-mentioned, for example, you may comprise by elements, such as hardware, such as a circuit board, or one IC (Integrated Circuit), and as any form Can also be used. In addition, by adopting a configuration that allows reading from a program or a separate recording medium, handling is easy, and usage can be easily expanded.

  The method for moving the sound image localization is not limited to the process of changing the parameter value of the pan pot, and other parameter values may be changed. Furthermore, not only the MIDI message but also any method can be used such as changing the output value from each speaker using a DSP as described above. As shown in FIG. 6, the sound image localization is moved in the left-right direction by setting the panpot parameter value (panpot LR), and the sound components in the left and right channels are set so that the sound image localization is further moved forward and backward. (Pan pot L-FR, pan pot R-FR). With this configuration, it is possible to move the sound image localization in the front / rear and left / right directions only by setting the parameter value of the pan pot without using the DSP.

  In addition, although the sound image localization of various sounds such as music information and alarm sounds has been moved, the alarm sound and sound data related to the state and situation of the vehicle do not move the sound image localization, for example, music information and TV sound data, For example, only the sound image localization of sound such as radio sound data may be moved. By adopting such a configuration, relatively important and urgent matters regarding the movement of the vehicle are appropriately notified, and a favorable movement of the vehicle can be obtained.

  In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.
