This pattern may be determined only by the output time indicated in period 1.

 In the item “volume” 1005, the volume of the sound output from the electronic device is registered.

Here, in the master table 1000, information that can specify the location where each electrical device is installed may be stored in association with each electrical device.

 FIG. 5 is an example of the sound list table 2000 stored in the storage unit 500. In the sound list table 2000, information on sound candidates to be output to the electric device 3 is registered. The sound list table 2000 stores a plurality of records having an item “frequency” 2001, an item “interval” 2002, and an item “volume” 2003.

 FIG. 6 is an example of the detection sound table 3000 stored in the storage unit 500. Information about the sound detected by the detection unit 100 is registered in the detection sound table 3000. The detection sound table 3000 stores a plurality of records having an item “time” 3001, an item “master ID” 3002, an item “frequency” 3003, an item “interval” 3004, and an item “volume” 3005.

In this case, the value stored in the item “ID” 1001 of the matching record is registered.

 For example, in the first record, the Japan standard time “April 8, 2013 00:00” registered in the item “time” 3001, “4” registered in the item “master ID” 3002, and the item “frequency” "1000" hertz registered in "3003", "C" registered in item "interval" 3004, and "40" decibel registered in item "volume" 3005 are stored in association with each other. . That is, at Japan standard time “April 8, 2013 00:00”, a sound of “40” decibels is detected at a frequency of “1000” Hertz at an interval of “C” pattern, and the frequency and the interval Indicates that it matches the ID “4” stored in the item “ID” 1000 stored in the master table 1000.

 Here, in the example of FIG. 6, an example is shown in which information on five items 3001 to 3005 is stored based on the sound detected by the detection unit 100, but information is not stored among these five items. There may be items. For example, in the third record, no information is stored in the item “master ID” 3001 and the item “interval” 3004. This indicates that the sound detected by the detection unit 100 is a sound that is not stored in the master table 1000.

 Hereinafter, an example of the sound detection operation by the sound control device 1 will be described with reference to the flowchart shown in FIG.

 In step S1, the detection unit 100 detects sound. Then, the detection unit 100 converts the sound into digital data.

 In step S2, the detection unit 100 identifies a sound component. Specifically, the detection unit 100 specifies the frequency band, interval, and volume of the sound from the digital data converted in step S1.

 In step S <b> 3, the detection unit 100 registers a record in the detection sound table 3000. Specifically, the detection unit 100 detects a record in which values are stored in the item “time” 3001, the item “master ID” 3002, the item “frequency” 3003, the item “interval” 3004, and the item “volume” 3005. Register to 3000.

 The item “time” 3001 stores the time when the detection unit 100 detects a sound in step S1. In the item “frequency” 3003, the frequency band specified by the detection unit 100 in step S2 is stored. The item “interval” 3004 stores the identifier of the interval specified by the detection unit 100 in step S2. In the item “volume” 3005, the volume specified by the detection unit 100 in step S2 is stored.

 Here, a value stored in the item “master ID” 3002 will be described. The detection unit 100 specifies a record in which the item “frequency” 1003 and the item “interval” 1004 match the key in the master table 1000, using the frequency band and interval of the sound specified in step S2 as keys. Then, the detection unit 100 refers to the value stored in the item “ID” 1001 of the identified record. Furthermore, the detection unit 100 stores the value in the item “master ID” 3002.

 An example of the sound control operation by the sound control device 1 according to the first embodiment will be described using the flowchart shown in FIG.

 In step S <b> 11, the input unit 200 accepts designation of an electrical device that changes sound to be output via a user operation or a network.

 In step S <b> 12, the specifying unit 310 specifies a sound that is not used by the electric device 3. Specifically, the specifying unit 310 refers to the item “time” 3001 of the detection sound table 3000. When the time stored in the item “time” 3001 is equal to or less than a predetermined time, for example, within 12 hours retroactively from the current time, the specifying unit 310 sets the item “frequency” 3003 corresponding to the record. Refers to the stored value. Further, the specifying unit 310 refers to the sound list table 2000 and stores a record in which the value is not stored in the item “frequency” 2001, that is, information on a time less than or equal to a predetermined time in the detection sound table 3000. Reference is made to a record in the sound list table in which a frequency value different from the frequency value of the record being stored is stored. The item referred to is not limited to the item “frequency” 2001. For example, the item “interval” 2002 or a combination of the item “frequency” 2001 and the item “interval” 2002 may be used.

 In step S13, the changing unit 320 updates the registered contents of the master table 1000. Specifically, the changing unit 320 specifies a record in the master table 1000 using the device name specified in step S11 as a key. And the change part 320 updates the registration content of the record of the master table 1000 based on the record of the sound list table 2000 referred at step S12. At this time, the value stored in the item “frequency” 1003 of the master table 1000 is changed to the value stored in the item “frequency” 2001 of the sound list table 2000. Further, the value stored in the item “interval” 1004 of the master table 1000 is changed to the value stored in the item “interval” 2002 of the sound list table 2000. Further, the value of the item “volume” 1005 in the master table 1000 is changed to the value stored in the item “volume” 2003 in the sound list table 2000.

 In step S14, the output unit 400 transmits an output instruction with the specified sound. Specifically, the output unit 400 transmits an output sound setting instruction to the electrical device 3 based on the content of the record in the master table 1000 updated in step S13. In other words, it can be said that the output unit 400 transmits a setting instruction for the sound output pattern (a combination of the frequency of the output sound and the interval pattern in the above embodiment).

 Note that step S13 and step S14 may be after step S12, and the order may be changed.

 For example, when the designation of “air conditioner” is accepted in step S11 and the frequencies “1000”, “2050”, and “3000” are read out in S12 with reference to the detection sound table 3000 in the state of FIG. From the sound list table 2000, the record of the frequency “1050” is specified.

 FIG. 12 is a diagram for explaining a state in which the records before and after this processing are updated for the record 1100 in the master table 1000. As shown in the record 1100, when the air conditioner is initially set to output the A pattern sound at 1000 Hz, the sound detection table 3000 has already registered the 1000 Hz sound. Records from 2000 to 1050 Hz will be identified.

 In step S13, the record 1100 of the master table 1000 is updated with the frequency “1050”, the interval “B”, and the volume “30” of the record specified in the sound list table 2000, and the state of the record 1101 is obtained. In step S14, an instruction to output a sound having a volume of “30” decibel with a frequency of “1050” and an interval pattern of “B” is transmitted to “air conditioner”.

 That is, according to this process, the sound control device 1 designates the first electric device among the plurality of electric devices, and the electronic sound output by the second electric device among the plurality of electric devices. The second pattern is identified based on the instruction, and an instruction to output an electronic sound with a first pattern different from the second pattern is transmitted to the first electrical device. The output pattern is at least one of a sound frequency band, sound volume, and sound output time. Thereby, the sound control apparatus 1 can be in a state in which sounds output from a plurality of electric devices can be easily identified. As a result, the sound control apparatus 1 can set the sound output by the electric device so that the user can easily identify the sound output by the electric device.

 An example of the sound control operation by the sound control device 1 according to the second embodiment will be described using the flowchart shown in FIG. In the above-described embodiment, the input unit 200 accepts only the designation of the electric device that changes the sound. In the second embodiment, the input unit 200 accepts the designation of the electric device that changes the sound and the frequency band of the sound. In the second embodiment, the hardware configuration of the sound control device 1 is as shown in FIG. 2, the functional configuration is as shown in FIG. 3, the master table 1000 is as shown in FIG. 4, and the detected sound table is as shown in FIG.

 In step S <b> 21, the input unit 200 receives the designation of the device name of the electric device whose sound is to be changed and the frequency band of the sound to be changed via a user operation or a network. Then, the input unit 200 acquires a record in which the item “device name” 1002 of the master table 1000 matches the key, using the device name of the electric device as a key. For example, when an instruction to make a sound having a frequency of “2000” Hertz is received for “air conditioner”, the input unit 200 acquires the first record of the master table 1000 using “air conditioner” as a key.

 In step S22, the specifying unit 310 determines whether there is an electrical device that outputs sound using the frequency band for which the change instruction has been received. Specifically, the identification unit 310 reads a record other than the record acquired in step S21 in the master table 1000, and the value stored in the item “frequency” 1003 of the record and the sound received in response to the change instruction. Compare with the frequency band value. Then, the specifying unit 310 determines whether there is a record in which the value stored in the item “frequency” 1003 and the frequency band value of the sound for which the change instruction has been received exist. When there is a record in which the value stored in the item “frequency” 1003 is the same as the frequency band value of the sound for which the change instruction has been received, that is, another electrical device that uses the frequency received in step S21 Is present, the process proceeds to step S21 (step S22: YES). On the other hand, if there is no record in which the value stored in the item “frequency” 1003 and the frequency band value of the sound for which the change instruction has been received do not exist, that is, other records that use the frequency received in step S21. If there is no electrical device, the process proceeds to step S23 (step S22: NO).

  In step S23, the changing unit 320 updates the registered contents of the master table 1000. Specifically, the changing unit 320 changes the value stored in the item “frequency” 3003 in the record acquired in step S21 to the value of the frequency band for which the change instruction has been accepted in step S21.

  In step S24, the output unit 400 transmits an output sound setting instruction with the sound for which the change instruction has been received in step S21. Specifically, the output unit 400 transmits an output instruction to the electrical device 3 based on the content of the record of the master table 1000 changed in step S23. For example, an instruction to output a sound having a volume of “40” decibel with a frequency of “2000” Hertz and an “A” interval pattern is transmitted to “Air Conditioner”.

 As described above, when the sound control device 1 receives an instruction to output sound in the first frequency band to the first electric device among the plurality of electric devices, the sound control device 1 The second frequency band is identified based on the sound output from the second electrical device, and the first frequency band is different from the first frequency band when the first frequency band and the second frequency band are different. An instruction to output sound in one frequency band is transmitted. Therefore, the sound desired by the user can be assigned to each electric device.

As a result, even when a plurality of electrical devices that output similar tones, that is, alarm sounds having similar frequencies and intervals, are placed in close proximity and it is difficult to identify the sound, The sound output from the electrical device can be set in an easily identifiable state. As a result, the user can easily identify the sound output by the electric device. Further, the user can express the image of each electric device with sound. Furthermore, by designating a low frequency band, it is possible to make it easier for elderly people who have difficulty in listening to high frequencies to hear sound output from electrical equipment. In addition, what is allocated with respect to an electric equipment is not restricted to a frequency, an interval, and a volume. For example, a musical scale, rhythm, intonation, or a musical piece expressed in musical notes may be assigned.

An example of the sound control operation by the sound control device 1 according to the third embodiment will be described using the flowchart shown in FIG. Also in the third embodiment, the hardware configuration of the sound control device 1 is as shown in FIG. 2, the functional configuration as shown in FIG. 3, the master table 1000 as shown in FIG. 4, and the detected sound table as shown in FIG.

 In step S31, the detection unit 100 detects sound. Then, the detection unit 100 converts the sound into digital data. At this time, the detection unit 100 determines whether or not a predetermined change or more has occurred in the volume of sound detected by the detection unit 100.

 Specifically, referring to the item “time” 3001 of the detection sound table 3000, a record in which the time stored in the item “time” 3001 is equal to or less than a predetermined time, for example, within 6 hours retroactively from the current time. Identify. Then, the plurality of specified records are divided at predetermined time intervals based on the time, the average sound volume is obtained based on the item “volume” 3005 stored in each, and the average volume according to the passage of time It is determined whether or not the change in the value is greater than or equal to a predetermined value, that is, whether or not the change is greater than a certain threshold value.

 When the change more than a threshold value arises, it transfers to step S31 (step S31: YES). On the other hand, when the change beyond a threshold value has not arisen, it transfers to step S32 (step S31: NO). Here, the range of time retroactive from the current time and the threshold value can be set as appropriate by the user.

 For example, in the case where the average value of the volume from the past 6 hours to 1 hour is “40” decibels, and the average value of the sound volume from the past one hour to the present time, that is, the most recent 1 hour, is “50” decibels. If it is 10 dB, it is determined that a change has occurred.

 In step S32, the processing unit 300 determines how to change the output sound. Specifically, the processing unit 300 specifies a coefficient based on the change determined in step S31. Specifically, a coefficient smaller than 1 is specified in the direction in which the volume change decreases, that is, when the average value of the volume for the most recent hour is smaller than the average of the previous volume. On the other hand, in the direction in which the volume change increases, that is, when the average value of the volume over the last hour is greater than the average of the previous volume, the processing unit 300 identifies a coefficient greater than 1. Note that the threshold value for determining that the value has become smaller and the threshold value for determining that the value has become larger may be the same value, or different values may be set for each.

 In step S <b> 33, the changing unit 310 updates the registered contents of the master table 1000. Specifically, the changing unit 310 changes, for each record in the master table 1000, each value stored in the item “volume” 1005 to a value obtained by multiplying the value and the coefficient specified in step S22. To do. For example, when the coefficient specified in step S22 is “1.5”, “40” decibel stored in the item “volume” 1005 of the first record is changed to “60” decibel, and the second record The item “50” decibel is changed to “75” decibel.

 In step S <b> 34, the output unit 400 transmits an instruction to output sound to the electrical device 3 in the determined change manner. Specifically, for each of the electrical devices 3 stored in the item “device name” 1002 of the master table 1000, the output unit 400 has an item “frequency” 1003 and an item “item” corresponding to the item “device name” 1002. An output sound setting instruction is transmitted with the values stored in the “interval” 1004 and the item “volume” 1005, respectively. For example, the output unit 400 transmits an instruction to output sound at intervals of “1000” hertz, “60” decibels, and “A” patterns to “air conditioner”.

 In this way, the sound control device 1 determines whether or not a predetermined change or more has occurred in the sound volume, and when the predetermined or more change occurs, the sound control device 1 Send an instruction to increase the size. Or the sound control apparatus 1 transmits the instruction | indication which makes the magnitude | size of the sound output with respect to an electric equipment small. Thereby, the volume of the sound output from the electric device can be changed according to the indoor noise level. For example, when the indoor noise level is high, the sound output from the electric device can be set large. Therefore, when the sound emitted from the electric device is detected by the detection unit 100, it is possible to prevent a situation in which the sound emitted from the electric device cannot be detected due to being buried in the noise. Further, even when the indoor noise level is high, it is possible to prevent the user from missing the sound output from the electric device.

 On the other hand, if the room is quiet, the sound output from the electrical device can be set to be small. For example, in a quiet environment such as sleeping, it is possible to prevent a situation in which an alarm sound that is louder than necessary is output from the electric device, so that the user's comfort can be improved.

 In the above example, the processing focusing on the sound volume has been described. However, the frequency may be processed instead of the sound volume or together with the sound volume. In that case, in step S31, the plurality of identified records are separated at predetermined time intervals based on the time, and each frequency appears according to the passage of time by referring to the item “frequency” 3003 stored therein. It is determined whether the change in frequency is equal to or greater than a threshold value. In that case, for an electrical device that sets a sound in a frequency band with a high appearance frequency, a sound in a frequency band with a low appearance frequency is specified from the sound list table 2000, and the sound is output at the specified frequency. As described above, it is conceivable to transmit an output sound pattern setting instruction to an electrical device.

 The above embodiments can be implemented in combination with each other without departing from the object. In the above embodiment, the sound list table 2000 has been described using an example of one type. However, a plurality of types of sound list tables 2000 can be stored in the storage unit 500. For example, a tone list table is classified according to the type of tone, such as a tone group imitating a piano tone, another tone list table imitating a trumpet tone, and the like. The sound list table to be used may be determined in the processing of the above-described embodiment according to the operation instruction from.

  In addition, a plurality of sound detection devices 13 are connected to the sound control device 1, information that can specify the installation location of the electrical device is stored in each record of the master table 1000, and the record is stored in each record of the detection sound table 3000. When the information for identifying the sound detection device 13 that has detected the sound shown in FIG. 5 is stored, the processing of each of the above embodiments is executed only for the electrical device installed at a specific location designated by the user. You can also For example, when the electrical device that has received the designation from the user is “air conditioner”, information that can specify the installation location of the electrical device in the record storing “air conditioner” is read from the master table 1000. Then, in the processing step of referring to the detection sound table 3000, not all of the records included in the predetermined time range are to be read out, but information on the sound detection device 13 installed at the place where the “air conditioner” is installed. Only records in which are stored can be read. In this way, for example, if there are a plurality of rooms in one building and the sound detection device 13 is installed in each room, only the electrical equipment installed in any of the rooms is processed. The processing shown in the flow of FIG. 9, the flow of FIG. 10, and the flow of FIG. 11 can be executed as an object.
