  For example, in Table 1, the control operation “air conditioner on” is associated with the control ID “xxx1001”, and the control operation “TV off” is associated with the control ID “xxx2000”. Although not essential, the information indicating the correspondence between the control operation and the control ID may store the correspondence between the voice command (voice command) and the control ID.

The sound wave that it has is output.

  The sound wave output unit (first sound wave output unit) 623 outputs a sound wave having a control ID under the control of the output control unit 622. For example, when the sound wave signal having the control ID received by the communication unit 621 is input to the sound wave output unit 623 by the output control unit 622, the sound wave output unit 623 is input using the sound I / F 305 and the speaker 307 in FIG. 3. The sound wave signal having the control ID is converted into a sound wave having the control ID and output.

  The sound wave acquisition unit 624 acquires sound waves around the sound wave output device 101 using, for example, the microphone 306 and the sound I / F 305 in FIG. 3. For example, the sound wave acquisition unit 624 acquires a sound wave or the like output by the control device 102.

The sensor processing by the sensor control unit 628 will be described later in the third embodiment.

  The operation reception unit 629 receives, for example, an operation of the user 105 on the operation unit 303 or the like in FIG. For example, the operation reception unit 629 receives a control ID registration operation, a deletion operation, or the like by the user 105.

Note that at least a part of the above functional configurations may be realized by hardware.

  The sound wave acquisition unit 641 acquires sound waves around the control device 102 using, for example, the microphone 405 and the sound I / F 404 in FIG. 4. For example, the sound wave acquisition unit 641 acquires a sound wave having the control ID output by the sound wave output device 101, converts the acquired sound wave into a sound wave signal, and outputs the sound wave signal to the identification information acquisition unit 642.

  The identification information acquisition unit 642 acquires the control ID included in the sound wave acquired by the sound wave acquisition unit 641. For example, as described above, when the control ID is represented by using the seven frequencies f1, f2, ..., F7, the identification information acquisition unit 642 analyzes the sound wave signal output by the sound wave acquisition unit 641. Then, the presence or absence of a sound wave is determined for each of the frequencies f1, f2, ..., F7. Further, the identification information acquisition unit 642 sets, for each of the frequencies f1, f2, ..., F7, the bit corresponding to the frequency at which the sound wave is output as “1”, and the bit corresponding to the frequency at which the sound wave is not output. The control ID is acquired by setting the value to "0".

  The conversion unit 643 converts the control ID acquired by the identification information acquisition unit 642 into a control signal for controlling the device 103. For example, the control information management unit 648 stores and manages, in the storage unit 649 or the like, information indicating the correspondence relationship between the control ID and the control signal for controlling the device 103 as shown in Table 2.

  Based on this correspondence, the conversion unit 643 can convert the control ID acquired by the identification information acquisition unit 642 into a control signal for controlling the device 103.

  The control signal output unit 644 outputs the control signal converted by the converter 643 for controlling the device 103. For example, when the control signal converted by the conversion unit 643 is the “light emission pattern A”, the control signal output unit 644 uses the infrared transmission / reception unit 647 to emit infrared light in the “light emission pattern A”.

  The sound wave output unit (second sound wave output unit) 645 outputs a sound wave using, for example, the speaker 406, the sound I / F 404, and the like in FIG. 4. For example, the sound wave output unit 645 converts the sound wave signal having the state ID output from the state information transmission unit 646 into a sound wave and outputs the sound wave.

  The state information transmission unit 646 generates a sound wave signal having a state ID indicating the state of the control device 102 and outputs the sound wave signal to the sound wave output unit 645, thereby causing the sound wave output unit 645 to output the sound wave having the state ID.

  The infrared transmission / reception unit 647 transmits / receives an infrared signal using the infrared transmission / reception device 407 of FIG. 4, for example. For example, the infrared transmission / reception unit 647 transmits an infrared signal that controls the device 103 under the control of the control signal output unit 644. Further, the infrared transmission / reception unit 647 functions as an infrared reception unit that receives an infrared signal output from, for example, a remote controller for the device 103, under the control of the control information management unit 648.

  The control information management unit 648 stores and manages, in the storage unit 649, information indicating the corresponding relationship between the control ID and the control signal as shown in Table 2 above. Further, the control information management unit 648, in accordance with the control by the sound wave from the sound wave output device 101, shows the correspondence relationship between the new control ID and the control signal, and the correspondence relationship between the control ID and the control signal as shown in Table 2. You can register to the information shown. Further, the control information management unit 648, in accordance with the control by the sound wave from the sound wave output device 101, specifies the control ID and the correspondence relationship from the information indicating the correspondence relationship between the control ID and the control signal as shown in Table 2.

  In step S704, the user 105 performs a control operation on the control operation acceptance screen displayed by the terminal device 104. For example, the user 105 selects one control command from the list of control commands displayed on the control operation acceptance screen.

  In step S705, the operation reception unit 611 of the terminal device 104 receives the control operation by the user 105, and the sound wave signal generation unit 612 generates a sound wave signal having a control ID corresponding to the received control operation. For example, the sound wave signal generation unit 612 specifies the control ID corresponding to the control operation by using the information indicating the correspondence relationship between the control operation and the control ID as shown in Table 1, and the sound wave having the specified control ID. Generate a signal.

  In step S <b> 706, the communication unit 613 of the terminal device 104 transmits the sound wave signal having the control ID created by the sound wave signal generation unit 612 to the sound wave output device 101 via the communication network 106. For example, the communication unit 613 transmits the sound wave signal (sound signal or sound data) having the control ID generated by the sound wave signal generation unit 612 to the sound wave output device 101.

  In step S707, when the communication unit 621 receives the sound wave signal having the control ID transmitted from the terminal device 104, the output control unit 622 of the sound wave output device 101 outputs the received sound wave signal to the sound wave output unit 623. .

  In step S708, the sound wave output unit 623 of the sound wave output device 101 converts the sound wave signal having the control ID output from the output control unit 622 into a sound wave having the control ID and outputs the sound wave.

  In step S709, the sound wave acquisition unit 641 of the control device 102 acquires the sound wave having the control ID output by the sound wave output device 101, and the identification information acquisition unit 642 determines the control ID of the sound wave acquired by the sound wave acquisition unit 641. get.

  In step S710, the conversion unit 643 of the control device 102 uses the information indicating the correspondence relationship between the control ID and the control signal as shown in Table 2 to obtain the control ID acquired by the identification information acquisition unit 642 from the device 103. Is converted into a control signal for controlling.

  In step S711, the control signal output unit 644 of the control device 102 outputs the control signal converted by the conversion unit 643 for controlling the device 103 to the device 103.

  For example, it is assumed that the sound wave output from the sound wave output device 101 has the control ID “xxx1001”, and as shown in Table 2, the control signal corresponding to the control ID “xxx1001” is the “light emission pattern A”. In this case, the control device 102 outputs the infrared signal of the light emission pattern A to the device 103.

  In step S712, the device 103 executes processing according to the control signal output from the control device 102.

  By the above process, for example, when the control selected by the user 105 is “air conditioner on” in step S704 and the device 103 is the air conditioner, the air conditioner (device 103) is operated according to the operation of the user 105. Power is controlled to on.

  According to the present embodiment, in the control system 100 that controls the device 103 from the terminal device 104 via the control device 102, the control device 102 that controls the device 103 can be realized with a simpler configuration.

[Second Embodiment]
FIG. 8 is a diagram showing an example of the system configuration of the control system according to the second embodiment. As shown in FIG. 8, when the user 105 is in a building 107 such as a house or office, it is desirable that the device 103 can be controlled without using the terminal device 104.

  In the second embodiment, an example in which the user 105 can control the device 103 without using the terminal device 104 when the user 105 is in a building 107 such as a house or an office will be described.

<Functional configuration>
The hardware configurations of the sound wave output device 101 and the control device 102 according to the second embodiment may be the same as those in the first embodiment. Further, the functional configuration of the control device 102 according to the second embodiment may be the same as that of the first embodiment. Here, the functional configuration of the sound wave output device 101 according to the second embodiment will be described.

  FIG. 9 is a diagram illustrating an example of a functional configuration of the sound wave output device 101 according to the second embodiment. As shown in FIG. 9, a sound wave output device 101 according to the second embodiment has a functional configuration of the sound wave output device 101 according to the first embodiment shown in FIG. 902, a sound wave signal generation unit 903, and the like.

  The voice acquisition unit 901 is realized by a program executed by the CPU 301 of FIG. 3, for example, and acquires the voice uttered by the user 105 using the microphone 306, the voice I / F 305, and the like of FIG. For example, the voice acquisition unit 901 acquires the voice of the voice command issued by the user 105.

  The voice recognition unit (second voice recognition unit) 902 is realized by, for example, a program executed by the CPU 301 of FIG. 3, performs voice recognition processing on the voice acquired by the voice acquisition unit 901, and recognizes a voice command. To do.

  The sound wave signal generation unit (second sound wave signal generation unit) 903 is realized by, for example, a program executed by the CPU 301 of FIG. When the voice recognition unit 902 can recognize the voice command, the sound wave signal generation unit 903 has a sound wave signal (second sound wave signal) having a control ID (second identification information) corresponding to the recognized voice command. To generate.

  For example, the sound wave output device 101 has information as shown in Table 3 indicating the correspondence between voice commands and control IDs.

表３は、ボイスコマンドと制御ＩＤとの対応関係を示す情報の一例を示している。

Table 3 shows an example of information indicating the correspondence between voice commands and control IDs.

  For example, in Table 3, the voice command “air conditioner on” is associated with the control ID “xxx1001”, and the voice command “television off” is associated with the control ID “xxx2000”.

  The sound wave signal generation unit 903 can specify the control ID corresponding to the recognized voice command based on this correspondence. Further, the sound wave signal generation unit 903 generates a sound wave signal representing the specified control ID by turning on / off sound waves at a plurality of frequencies, for example, as described above.

  Further, when the communication unit 621 receives a sound wave signal (first sound wave signal) having a control ID (first identification information), the output control unit 622 according to the second embodiment outputs the received sound wave signal. The sound is output to the sound wave output unit 623.

  On the other hand, when the voice acquisition unit 901 acquires voice, the output control unit 622 outputs the acquired voice to the voice recognition unit 902. Thus, when the voice acquired by the voice acquisition unit 901 includes a voice command, the sound wave output unit 623 outputs a sound wave having a control ID (second identification information) corresponding to the voice command.

  The functional configuration of the sound wave output device 101 other than the above may be the same as that of the first embodiment.

<Process flow>
Next, a processing flow of the control method according to the second embodiment will be described.

(Output control process)
FIG. 10 is a flowchart showing an example of output control processing according to the second embodiment. This process shows an example of the output control process executed by the output control unit 622 of the sound wave output device 101. For example, the sound wave output device 101 repeatedly executes the output control process shown in FIG. 10.

  In step S1001, the output control unit 622 of the sound wave output device 101 determines whether the sound acquisition unit 901 has acquired sound. As an example, the output control unit 622 may determine that the sound has been acquired when the sound acquisition unit 901 has acquired a sound volume higher than a predetermined volume.

  When the voice acquisition unit 901 acquires a voice, the output control unit 622 shifts the processing to step S1002. On the other hand, when the audio acquisition unit 901 has not acquired the audio, the output control unit 622 shifts the processing to step S1007.

  When the process proceeds to step S1002, the output control unit 622 outputs the voice acquired by the voice acquisition unit 901 to the voice recognition unit 902.

  In step S1003, the voice recognition unit 902 performs voice recognition processing on the voice acquired by the voice acquisition unit 901 and recognizes a voice command.

  In step S1004, the voice recognition unit 902 branches the process depending on whether a voice command is recognized. When the voice command is recognized, the voice recognition unit 902 shifts the processing to step S1005. On the other hand, when the voice command is not recognized, the voice recognition unit 902 ends the process.

  Upon proceeding to step S1005, the voice recognition unit 902 notifies the sound wave signal generation unit 903 of the recognized voice command. Further, the sound wave signal generation unit 903 creates a sound wave signal having a control ID corresponding to the notified voice command, and outputs the sound wave signal to the sound wave output unit 623.

  On the other hand, when the process proceeds from step S1001 to step S1007, the output control unit 622 of the sound wave output device 101 determines whether the communication unit 621 has received the sound wave signal having the control ID from the terminal device 104.

  When the sound wave signal having the control ID is not received from the terminal device 104, the output control unit 622 ends the process. On the other hand, when the sound wave signal having the control ID is received from the terminal device 104, the output control unit 622 outputs the received sound wave signal to the sound wave output unit 623.

  Through the above processing, when the user 105 is inside the building 107 such as a house or office, the sound wave output device 101 can control the control ID according to the voice command uttered by the user 105 without using the terminal device 104. It becomes possible to output a sound wave having

(Processing of control system)
FIG. 11 is a sequence diagram showing an example of processing of the control system according to the second embodiment. This process shows an example of the process of the control system 100 when the user 105 is in a building 107 such as a house or office, as shown in FIG.

  As shown in FIG. 1, when the user 105 is outside the building 107, the same processing as the processing of the control system according to the first embodiment shown in FIG. 7 is performed also in the second embodiment. Executed. Further, since the processing after step S708 of FIG. 11 is the same as the processing of the control system according to the first embodiment shown in FIG. 7, a description will be given here focusing on the differences from the first embodiment.

  In step S1101, the user 105, for example, as shown in FIG. 8, utters a voice command to the sound wave output device 101.

  In step S1102, when the voice acquisition unit 901 of the sound wave output device 101 acquires the voice generated by the user 105, the output control unit 622 outputs the acquired voice to the voice recognition unit 902. Note that this processing corresponds to the processing of steps S1001 and S1002 in FIG.

  In step S1103, the voice recognition unit 902 of the sound wave output device 101 performs voice recognition processing on the voice acquired by the voice acquisition unit 901 and recognizes a voice command. Note that this process corresponds to the process of step S1003 in FIG. In addition, here, it is assumed that the voice command uttered by the user 105 is recognized in step S1101.

  In step S1104, the sound wave signal generation unit 903 of the sound wave output device 101 generates a sound wave signal having a control ID corresponding to the voice command recognized by the voice recognition unit 902. Note that this process corresponds to the process of step S1005 of FIG.

  In step S1005, the sound wave signal generation unit 903 of the sound wave output apparatus 101 outputs the created sound wave signal to the sound wave output unit 623. Note that this process corresponds to the process of step S1006 in FIG.

  Through the above processing, the sound wave output device 101 can output the sound wave having the control ID corresponding to the voice command generated by the user 105.

  Therefore, according to the second embodiment, when the user 105 is inside the building 107 such as a house or an office, the device 103 can be controlled without using the terminal device 104.

[Third Embodiment]
In the third embodiment, an example of suitable processing applicable to the first and second embodiments will be described.

(Communication control by sound waves)
FIG. 12 is a flowchart showing an example of communication control by sound waves according to the third embodiment. This process shows an example of communication control suitable when performing communication by sound waves between the sound wave output device 101 and the control device 102. For example, in step S708 of FIGS. 7 and 11, when outputting the sound wave having the control ID from the sound wave output device 101 to the control device 102, the communication control process shown in FIG. 12 can be applied.

  First, the processing of the control device 102 will be described with reference to FIG.

  In step S1201, the control device 102 is in a standby state. In this state, for example, in step S1212, the sound wave output device 101 outputs a sound wave having a control ID, which instructs the control device 102 to output a control signal.

  In step S1202, the control device 102 starts the output processing of the control signal shown in steps S709 to S711 of FIG. 7, for example.

  In step S1203, the state information transmission unit 646 of the control device 102 outputs the sound wave having the state ID (state information) indicating that the output of the control signal is started, using the sound wave output unit 645.

  The sound wave having the state ID can be generated, for example, in the same manner as the sound wave having the control ID described above.

  In steps S1204 and S1205, when the control device 102 ends the output of the control signal, the state information transmission unit 646 transmits the sound wave having the state ID (state information) indicating that the output of the control signal has ended to the sound wave output unit. And output using 645.

  Next, the processing of the sound wave output device 101 will be described with reference to FIG.

  In steps S1211 and S1212, the sound wave output unit 623 of the sound wave output apparatus 101 outputs a sound wave having a control ID, which instructs the output of the control signal. It should be noted that this process corresponds to, for example, the process of step S708 in FIG.

  In step S1213, the state information acquisition unit 625 of the sound wave output device 101 resets the value of the counter i to, for example, “0”.

  In step S1214, the state information acquisition unit 625 of the sound wave output device 101 determines whether or not the control device 102 has started the output of the control signal. For example, the state information acquisition unit 625 can determine that the control device 102 has started the output of the control signal when the state ID indicating that the output of the control signal has been started is acquired from the control device 102.

  When the control device 102 starts outputting the control signal, the sound wave output device 101 shifts the processing to step S1218. On the other hand, when the control device 102 has not started to output the control signal, the sound wave output device 101 shifts the processing to step S1215.

  When the process proceeds to step S1215, the state information acquisition unit 625 determines whether the value of the counter i is larger than the predetermined timer value T1. When the value of the counter i is larger than the timer value T1, the state information acquisition unit 625 shifts the processing to step S1217. On the other hand, when the value of the counter value i is less than or equal to the timer value T1, the state information acquisition unit 625 shifts the processing to step S1216.

  When the process proceeds to step S1216, the state information acquisition unit 625 adds "1" to the value of the counter i, returns the process to step S1214, and executes the same process again.

  On the other hand, when the process proceeds to step S1217, the state information acquisition unit 625 determines that the communication using the sound wave has not been correctly performed, and notifies the user 105 of the abnormality.

  When the process proceeds from step S1214 to S1218, the state information acquisition unit 625 resets the value of the counter j to “0”, for example.

  In step S1219, the state information acquisition unit 625 of the sound wave output device 101 determines whether the control device 102 has finished outputting the control signal. For example, when the status information acquisition unit 625 acquires from the control device 102 a status ID indicating that the output of the control signal has ended, the control device 102 can determine that the control device 102 has ended the output of the control signal.

  When the control device 102 ends the output of the control signal, the sound wave output device 101 ends the communication control process by the sound wave. On the other hand, when the control device 102 has not finished outputting the control signal, the sound wave output device 101 shifts the processing to step S1220.

  When the process proceeds to step S1220, the state information acquisition unit 625 determines whether the value of the counter j is larger than the predetermined timer value T2. When the value of the counter j is larger than the timer value T2, the state information acquisition unit 625 shifts the processing to step S1222. On the other hand, when the value of the counter j is less than or equal to the timer value T2, the state information acquisition unit 625 shifts the processing to step S1221.

  When the process proceeds to step S1221, the state information acquisition unit 625 adds “1” to the value of the counter j, returns the process to step S1219, and executes the same process again.

  On the other hand, when the process proceeds to step S1222, the state information acquisition unit 625 determines that the communication by the sound wave has not been correctly completed, and notifies the user 105 of the abnormality.

  Through the above processing, the sound wave output device 101 can perform communication by sound waves while confirming the state of the control device 102 based on the sound wave having the state ID transmitted from the control device 102.

(Registration process of control ID)

Report that the preparation is complete.

  In steps S1309 and S1310, the registration control unit 626 of the sound wave output apparatus 101 notifies the user 105 that the preparation for the registration mode is completed, for example, by LED display or screen display by the operation unit 303 in FIG. Alternatively, the registration control unit 626 may notify the user 105 that the preparation for the registration mode is completed, for example, by a voice message such as “Start registration”.

  In steps S1311, S1312, the user 105 registers a voice command with the sound wave output device 101. For example, the user 105 utters a voice command that he / she wants to register, such as “Television on”.

  In step S1313, the registration control unit 626 of the sound wave output device 101 registers the correspondence relationship between the voice command uttered by the user 105 and the control ID to be newly registered (hereinafter referred to as a new ID). For example, the registration control unit 626 registers the correspondence between the voice command uttered by the user 105 and the new ID in the information indicating the correspondence between the voice command and the control ID as shown in Table 3.

  In step S1314, the registration control unit 626 of the sound wave output device 101 notifies the control device 102 of the information of the new ID, for example, by outputting a sound wave having the new ID.

  In step S1315, the registration control unit 626 of the sound wave output device 101 notifies the user 105 that the ID registration is completed, for example, by LED display or screen display by the operation unit 303 in FIG. Alternatively, the registration control unit 626 may notify the user 105 that the preparation for the registration mode is completed, for example, by a voice message such as “please press the button to register”.

  In steps S1316 and S1317, the user 105 points the remote controller controlling the device 103 toward the control device 102 and operates the button associated with the voice command. Thereby, the infrared signal of the light emission pattern corresponding to the operated button is output from the remote controller to the control device 102.

  In step S1318, the control information management unit 648 of the control device 102 uses the infrared transmission / reception unit 647 to acquire the light emission pattern of the infrared signal output from the remote controller. Further, the control information management unit 648 shows the correspondence relationship between the emission pattern of the acquired infrared signal and the new ID acquired in step S1314, for example, the correspondence relationship between the control ID and the control signal as shown in Table 2. Register with the information shown.

  In step S1319, the control information management unit 648 of the control device 102 outputs a sound wave having a predetermined state ID to report to the sound wave output device 101 that the registration of the new ID is completed.

  In steps S1320 and S1321, the registration control unit 626 of the sound wave output apparatus 101 notifies the user 105 that the control ID registration is completed, for example, by LED display or screen display by the operation unit 303 in FIG. Alternatively, the registration control unit 626 may notify the user 105 that the preparation for the registration mode is completed, for example, by a voice message such as “registration is completed”.

  Through the above processing, the user 105 can register the new control ID in the control system 100 in association with the voice command.

(Control ID deletion processing)
FIG. 14 is a flowchart showing an example of control ID deletion processing according to the third embodiment. This processing shows an example of the deletion processing for deleting the control ID registered in the control system 100.

  In steps S1401 and S1402, it is assumed that the sound wave output device 101 and the control device 102 are in the standby mode.

  In steps S1403 and S1404, the user 105 operates the sound wave output device 101 to switch to the deletion mode. For example, the user 105 operates the operation unit 303 of the sound wave output device 101 to switch to a predetermined deletion mode. Alternatively, the user 105 may perform the switching operation to the registration mode by a voice command such as “start deletion”.

  In step S1405, the registration control unit 626 of the sound wave output apparatus 101 starts preparation for the deletion mode.

  In step S1406, the registration control unit of the sound wave output device 101 outputs a sound wave having a predetermined control ID to instruct the control device 102 to switch to the deletion mode.

  In steps S1407 and S1408, the control information management unit 648 of the control device 102 prepares for the deletion mode, and when the preparation is completed, the sound wave having the predetermined state ID is output to output the sound wave output device 101 to the deletion mode. Report that the preparation is complete.

  In steps S1409 and S1410, the registration control unit 626 of the sound wave output apparatus 101 notifies the user 105 that the preparation for the deletion mode is completed, for example, by LED display or screen display by the operation unit 303 in FIG. Alternatively, the registration control unit 626 may notify the user 105 that the preparation for the deletion mode is completed, for example, by a voice message such as “Please specify a command to be deleted”.

  In steps S <b> 1411 and S <b> 1412, the user 105 operates the sound wave output device 101 to specify a control ID to be deleted by a voice command, a button operation, or the like. For example, when deleting the control ID corresponding to the “TV ON” voice command, the user 105 utters the “TV ON” voice command to the sound wave output device 101.

  In step S1413, the registration control unit 626 of the sound wave output device 101 deletes the correspondence between the voice command uttered by the user 105 and the control ID (hereinafter, referred to as a designated ID) corresponding to the voice command. For example, the registration control unit 626 deletes the correspondence between the designated ID and the voice command, which is registered in the information indicating the correspondence between the voice command and the control ID as shown in Table 3.

  In step S1414, the registration control unit 626 of the sound wave output device 101 notifies the control device 102 of the information of the specified ID, for example, by outputting a sound wave having the specified ID.

  In step S1415, the registration control unit 626 of the sound wave output device 101 notifies the user 105 of the start of the deletion work of the designated ID, for example, by LED display or screen display by the operation unit 303 in FIG. Alternatively, the registration control unit 626 may notify the user 105 that the deletion work has started by a voice message such as “Start deletion of the designated ID”.

  In step S1416, the control information management unit 648 of the control device 102 determines the correspondence relationship between the designated ID and the control signal acquired in step S1414, for example, the correspondence relationship between the control ID and the control signal as shown in Table 2.

  Through the above processing, the user 105 can delete the control ID registered in the control system 100 in association with the voice command from the control system 100.

(Timer processing)
FIG. 15 is a flowchart showing an example of timer processing according to the third embodiment. The sound wave output device 101 includes a timer control unit 627 that causes the sound wave output unit 623 to output a sound wave having a predetermined control ID at a designated time. FIG. 15 shows an example of timer processing by the timer control unit 627. At the start of the process shown in FIG. 15, the sound wave output device 101 is preset with a sound wave having a predetermined control ID to be output by the timer process, a time for outputting a sound wave having a predetermined control ID, and the like. It is assumed that

  In steps S1501 and S1502, the sound wave output device 101 and the control device 102 are in a standby state.

Thereby, in step S1505, the sound wave output unit 623 outputs a sound wave having a predetermined control ID.

  In step S1506, the control device 102 acquires the control ID from the sound wave output from the sound wave output device 101, and starts outputting the control signal corresponding to the acquired control ID.

  Through the above processing, the user 105 can cause the device 103 to perform a predetermined operation (for example, turning on / off the power) at a designated time from a remote place or the like.

  Note that, in FIG. 15, an example in which the sound wave output device 101 outputs a predetermined control ID at a designated time has been described, but the sound wave output device 101 detects a predetermined sensor as shown in FIG. 16.
