Description

  The present invention relates to a portable terminal such as a mobile phone, a mobile computer, and a portable information device. In particular, the present invention relates to a mobile terminal that displays an alarm for a specific sound from the surroundings.

  For example, when traveling on a train or bus while listening to music with headphones or reading a book or magazine, you may be immersed in listening to music or reading, and you may get through without knowing that you have arrived at the station where you should get off. . In order to prevent such a situation, it is effective to set the alarm display function (blinking alarm lamp, alarm sound, vibrator vibration, etc.) in advance for the mobile phone etc., but the alarm function is set. I often forget what I do. Therefore, it is desirable that such an alarm display function be automatically activated without prior setting.

  By the way, the station has sound information specific to the station. For example, there is a bell sound of a platform that rings when a train departs and arrives, and a melody sound peculiar to the station. Furthermore, when the train departs or arrives, there is a broadcast sound in the train such as “I will arrive at the station soon”. Therefore, it is conceivable to use voice recognition technology to automatically detect a specific sound related to a place or event from ambient sounds and automatically activate a function related to an alarm for each place or event.

  As a technique for detecting a specific voice from the surroundings, Patent Document 1 describes a technique for notifying a person who is in a call when it is called by a person in the vicinity during the call. However, this technology does not assume an alarm for various situations such as the above-mentioned prevention of overpass.

JP 2004-260754 A

  Accordingly, an object of the present invention is to provide a portable terminal that detects a specific sound peculiar to a place or event where an alarm is to be displayed and automatically activates a predetermined alarm display function.

  In order to solve the above problem, the present invention is a mobile terminal that displays or alarms predetermined information according to a specific sound input to the mobile terminal, and when a predetermined specific operation is performed, Specific sound information registration for inputting ambient sound from the vicinity of the portable terminal and registering information related to part or all of the input ambient sound signal as specific sound information in association with a predetermined function related to an alarm Any one of the specific sound information registered in the specific sound information registering means, and the ambient sound from the vicinity of the mobile terminal is input continuously or periodically, the signal of the input ambient sound is analyzed Specific sound detection means for detecting whether or not a signal corresponding to is included, and the specific sound detection means is registered in the specific sound information registration means in the input ambient sound signal Compatible with any of the sound information If it detects a signal is included that is characterized by starting the function of the alarm corresponding to the specific sound information.

  According to the present invention, a mobile terminal that automatically activates a predetermined function related to an alarm by detecting a specific sound specific to a place or event where an alarm should be displayed from surrounding sounds of the place where the terminal is present is provided. it can.

  In particular, the user of this terminal can register various specific sounds and a plurality of alarm display functions in association with each other freely. If you register in advance a specific sound that flows in the terminal, this terminal can automatically detect arrival at the getting-off station and activate the alarm function, if you forget the general alarm function set by time But you can reduce the chances of getting over.

  In addition, since any alarm display function can be associated according to the specific sound, for example, the specific sound generated in the train is not accompanied by a ringing sound such as vibrator vibration or alarm lamp blinking, It is also possible to selectively activate an alarm display function that does not bother people.

The internal block block diagram of the portable terminal by this invention Example of specific sound to be detected and display information Operational flow chart of portable terminal according to the present invention

  Hereinafter, a mobile terminal (hereinafter abbreviated as the present terminal) according to the present invention will be described with reference to the drawings, taking an alighting station arrival alarm for preventing overpass as an example.

  FIG. 1 is an internal block configuration diagram of the terminal 1. The terminal 1 includes a terminal control unit 10, an information registration unit 11, a sound information comparison processing unit 12, an operation unit 13, a sound input unit 14, a display unit 15, an audio reproduction unit 16, and an alarm unit 17.

  The terminal 1 may be a dedicated terminal for preventing overtime, or may be a terminal integrated with various portable terminals such as a mobile phone, a mobile computer, an electronic book, and a game machine.

It is a means to control the whole.

  The information registration unit 11 registers in advance the specific sound information generated at each station that gets on and off (departing bell sound, the name of the station that makes consecutive calls, etc.) and the alarm display information when the terminal 1 detects the specific sound information. It is a means to keep. The specific sound information is obtained by the person carrying the terminal 1 operating the operation unit 13 to record a desired sound, and then operating the operation unit 13 to specify a specific sound part. What is necessary is just to link and register.

  The alarm display information includes display contents on the display unit 15 (for example, “arrival at the getting-off station”), blinking of an alarm lamp and sound of an alarm sound by the alarm unit 17, and reproduction of alarm sound information by the sound reproduction unit 16. Any one or more. The contents displayed on the display unit 15 can be freely edited by operating the operation unit 13.

  The alarm display information may be contents selected by date and time. For example, if the specific sound of the nearest station at home is registered and the specific sound is detected during the commuting hours of work, it is determined that the work is in progress and is delayed / always as usual / always Information related to the passing time, such as earlier, is displayed, and when a specific sound is detected in addition to the commuting time zone, it may be determined that the user is on the way home and an alarm display function that prompts the user to get off is activated. .

  The sound information comparison processing unit 12 is means for comparing the ambient sound input from the sound input unit 14 with the specific sound information registered in the information registration unit 11 in response to an instruction from the terminal control unit 10. When it is detected that one of the specific sounds registered in the information registration unit 11 is included in the ambient sound input from the sound input unit 14, the terminal control unit 10 is notified accordingly. The comparison between the ambient sound and the specific sound may be made by comparing the frequency spectrum of the sound and checking its similarity.

  The operation unit 13 is a numeric keypad or a function key that allows a person carrying the terminal 1 to operate the terminal 1 and notifies the terminal control unit 10 of the input operation content. The operation unit 13 is an input device (for example, a tablet integrated with the display unit 15) provided in various mobile terminals such as a mobile phone, a mobile computer, an electronic book, and a game machine that integrate the functions of the terminal 1. Device).

  The sound input unit 14 is a sound input unit including a microphone that converts ambient sound generated around the terminal 1 into an electrical signal. The ambient sound signal converted into the electrical signal is the terminal control unit 10. And output to the sound information comparison processing unit 12. The sound input unit 14 may be a microphone provided in a mobile phone or the like that integrates the functions of the terminal 1.

  The display unit 15 is a unit (for example, a flat display such as an LCD) that displays characters, images, and the like according to instructions from the terminal control unit 10 and displays characters and images related to alarm contents and operation explanations. The display unit 15 may be a display device provided in various mobile terminals such as a mobile phone, a mobile computer, an electronic book, and a game machine that integrate the functions of the terminal 1.

  The audio reproduction unit 16 is an output unit including a speaker that reproduces an audio signal in response to an instruction from the terminal control unit 10 and reproduces, for example, an alarm message. The sound reproducing unit 16 may be a speaker provided in various portable terminals such as a mobile phone, a mobile computer, and a game machine that integrate the functions of the terminal 1.

  The alarm unit 17 is means for notifying an alarm to a person carrying the terminal 1 such as a buzzer, an LED, and a vibrator in accordance with an instruction from the terminal control unit 10. The alarm unit 17 may be a buzzer, an LED, a vibrator, or the like provided in various portable terminals such as a mobile phone, a mobile computer, an electronic book, and a game machine that integrate the functions of the terminal 1.

  FIG. 2 is an example of a specific sound to be detected and display information based thereon. The column 200 is an identification ID for identifying a specific sound, the column 201 is an example of a sound source from which the specific sound is extracted, the column 202 is a function activated corresponding to each specific sound, and the column 203 is corresponding to each specific sound. Display information displayed on the display unit 15 and a column 204 indicate the alarm contents of the alarm unit 17 corresponding to each specific sound.

  For example, in the case of specific sound 2, when an adjacent station name “X station” included in “Arrived at“ X station ”” flowing in the in-car broadcast of the boarding train is detected, the arrival station arrival alarm function (proximity) , "Next stop" is displayed, indicating that the alarm lights up. Also, the specific sound 4 is an example in which, when a specific melody flowing in the in-car broadcast of the train on board is detected, recording of the in-car broadcast (for example, arrival delay information) following the melody is automatically activated, Indicates to display time.

  FIG. 3 is an example of an operation flowchart of the terminal 1 relating to processing corresponding to the specific sound information shown in FIG. Hereinafter, the operation flow of the terminal 1 will be described with reference to FIGS. This flow starts with the power turned on (S300).

  In the standby state, the terminal control unit 10 circulates each NO of S301 and S302, and monitors the occurrence of each event of the presence / absence of the specific sound monitoring (S301) and the presence / absence of the specific operation (S302).

  In S302, when there is a specific operation (for example, pressing # 0 with the numeric keypad) (S302, YES), the terminal control unit 10 controls the sound input unit 14 to input ambient sound for a predetermined time and input it. The specific part of the ambient sound is registered as a specific sound in the information registration unit 11 in association with a desired function requested by the operator (specified by the operation unit 13), and the process returns to S301. The specific part (specific sound) of the input ambient sound may be trimmed and edited later (not shown). The process of S303 is repeated to register necessary specific sounds in advance.

  In S301, when there is an operation for starting monitoring of a specific sound from the operation unit 13 (for example, pressing # 1 with a numeric keypad) (S301, YES), the terminal control unit 10 determines a certain amount of time (for example, 10 seconds). Are input from the sound input unit 14, and the input ambient sound is output to the sound information comparison processing unit 12. Then, the sound information comparison processing unit 12 analyzes the input ambient sound and compares it with each specific sound registered in the information registration unit 11 (S310), and proceeds to S320 and subsequent steps, whether or not the specific sound 1 exists (S320), The presence / absence of the specific sound 2 (S330), the presence / absence of the specific sound 3 (S340), the presence / absence of the specific sound 4 (S350), and the presence / absence of other specific sounds (S360) are monitored. If there is no (S370, NO), the process returns to S310 and the loop of S310 to S370 is repeated.

  Here, if the cycle through the loop of S310 to S370 is short (for example, 0.1 seconds or less), the ambient sound that is missed in S310 is negligible, and there is no particular problem, but the missed input. In order to eliminate the ambient sound, the input of the ambient sound and the processes of S310 to S370 may be executed in parallel (not shown).

  In S320, when the specific sound 1 (departure bell) is detected in a state where the specific sound of another station is not detected (S320, YES), it can be estimated that the train is going somewhere in the train, so the terminal control unit 10 Displays a screen prompting the user to input the names of the getting-off station and the adjacent station on the display unit 15, and allows the person carrying the terminal 1 to input the names of the getting-off station and the adjacent station from the operation unit 13. And the terminal control part 10 memorize | stores the name of the input alighting station and an adjacent station in the information registration part 11 (S321), and returns to S310.

  Since the same specific sound may be detected many times while repeating S310 to S370 at a high speed, the detection of the same specific sound is performed, for example, only at the first detection or at regular intervals. It is sufficient that only the first detection is valid (not shown).

  In addition, when the specific sound 1 is used daily (for example, the nearest station at home or the commuting station), the exit station corresponding to the station (ride) or the adjacent station is registered. , S321 may be omitted (not shown).

  In S330, when the specific sound 2 (neighboring station name) is detected (S330, YES), the terminal control unit 10 approaches the person who carries the terminal 1, for example, a next stop station such as “Next stop station”. This information is displayed on the display unit 15 and the alarm unit 17 is controlled to alarm by red LED lighting, vibrator vibration, etc. (S331), and the process proceeds to S340.

  Note that if adjacent station information of the getting-off station is not registered in the information registration unit 11, the step of S330 is through (S330, NO).

  In S340, when the specific sound 3 (alighting station name) is detected (S340, YES), the terminal control unit 10 notifies the person carrying the terminal 1 of the arrival at the alighting station, and so on. Is displayed on the display unit 15 and the alarm unit 17 is controlled to give an alarm by blinking the red LED, vibrator vibration, or the like (S341), and the process proceeds to S350.

  In S350, when the specific sound 4 (specific melody) is detected (S350, YES), the recording of the in-car broadcast (for example, arrival delay information) following the melody flowing in the in-car broadcast of the boarding train is automatically started / stopped ( S351) The fact that the in-vehicle broadcast is recorded and the recording time are displayed on the display unit 15, and the process proceeds to S360. In addition, what is necessary is just to stop the recording after starting a recording automatically, for example, when a silence state more than a fixed time is detected (not shown).

  When other specific sound is detected in S360 (S360, YES), the terminal control unit 10 activates a corresponding function registered in the information registration unit 11 in association with the specific sound (S361), and proceeds to S370. . The other specific sounds include an arbitrary sound (for example, “Bento ~” issued by station lunch sales) and a display content when the person carrying the terminal 1 detects it (for example, “Station lunch sales”). Can be registered freely.

  In S370, when there is an operation (for example, pressing # 2 with the numeric keypad) to end the monitoring of the specific sound from the operation unit 13 (S370, YES), the terminal control unit 10 stops each activated function (S371). ), This flow ends (S372). If NO in S370, the process returns to S310.

  The flow of S310 to S370 described above is in line with the example of FIG. 2, but this is for easy explanation of the operation example of the terminal 1, and is not limited to the example of FIG. Actually, the specific sound detection judgment BOX in S320 to S360 is one, and when a specific sound is detected, the function corresponding to the detected specific sound is activated. That is, an arbitrary number of arbitrary specific sounds extracted from arbitrary sound sources and arbitrary display contents when the specific sounds are detected can be freely registered.

  As described above, according to the present invention, a specific sound peculiar to a place where an alarm should be displayed or an event is detected from surrounding sounds of the place where the terminal is present, and a predetermined function related to the alarm is automatically activated. In addition, there is an effect of preventing overpass and the like.

  In addition, although the sound in a station or a train was demonstrated to the example as a specific sound, if the specific sound and display information respond | correspond, various applications other than the use of preventing overpass are possible. For example, it can be applied to the use of preventing omission such as name call or number tag call waiting in turn in waiting rooms of hospitals, banks, stores and the like. In addition, the present invention can also be applied to prevention of oversight, such as calling for discount rates (XX% OFF, etc.) for bargain sales at each store in a shopping mall.
