[First Embodiment]
FIG. 1 shows an example of an outline of an electronic device control system according to a first embodiment of the present invention.

(Outline of electronic device control system 1)
The electronic device control system 1 according to the first embodiment selectively controls the operation of an arbitrary electronic device existing within a predetermined acoustic wave reachable range. Specifically, the electronic device control system 1 selectively or individually controls electronic devices existing in each of the plurality of regions. More specifically, the electronic device control system 1 uses a sound wave having a frequency that is difficult to perceive to human hearing or a frequency that is not perceived as a carrier wave of a control signal that controls the operation of the electronic device. When the electronic device control system 1 transmits the control signal from the electronic device control system 1 to the electronic device, the electronic device control system 1 selectively controls the sound pressure or the sound pressure level of the sound wave to a specific region. The sound wave is transmitted. Thereby, the electronic device control system 1 can selectively control the operation of the electronic device existing in the specific area.

  For example, as shown in FIG. 1, a case where there are a plurality of areas 60, areas 60a, and areas 60b where electronic devices exist will be described. The electronic device control system 1 can control one or more electronic devices existing in one area or a plurality of areas.

  In the example illustrated in FIG. 1, the toy 50 including the portable information terminal 26, the television 28, and the light emitting unit 500 exists in the region 60. In the region 60a, there is a toy 50a having a portable information terminal 26a, a television 28a, and a light emitting unit 500a. Similarly, a toy 50b having a portable information terminal 26b, a television 28b, and a light emitting unit 500b exists in the region 60b. Note that each of the portable information terminal, the television, and the toy has a microphone that receives sound waves from the output unit included in the electronic device control system 1.

  Here, the toy 50b of the toy 50 existing in the area 60 is caused to emit red light, the light emitting part 500a of the toy 50a existing in the area 60a is caused to emit yellow light, and the toy 50b existing in the area 60b. Let us consider a case where the light emitting section 500b emits blue light. In this case, the electronic device control unit 10 included in the electronic device control system 1 converts a control signal for causing the light emitting unit 500 to emit red light from the output unit 130a and outputs the sound wave 40a. In addition, the electronic device control unit 10 converts a control signal for causing the light emitting unit 500a to emit yellow light from the output unit 130b and outputs the sound wave 40b. Further, the electronic device control unit 10 converts a control signal for causing the light emitting unit 500b to emit blue light from the output unit 130c into a sound wave 40c and outputs the sound wave 40c.

  In this case, the electronic device control unit 10 outputs the sound wave 40 a from the output unit 130 a by controlling the sound pressure or the sound pressure level of the sound wave 40 a so that the sound wave 40 a selectively reaches the region 60. In addition, the electronic device control unit 10 outputs the sound wave 40b from the output unit 130b by controlling the sound pressure or the sound pressure level of the sound wave 40b so that the sound wave 40b selectively reaches the region 60a. Similarly, the electronic device control unit 10 outputs the sound wave 40c from the output unit 130c by controlling the sound pressure or the sound pressure level of the sound wave 40c so that the sound wave 40c selectively reaches the region 60b. Subsequently, each toy that has received the sound wave extracts a control signal from the sound wave. Each toy performs an operation according to the control signal.

  For example, the toy 50 thru | or toy 50b each have a control signal extraction part which extracts a control signal from the sound wave which the microphone and the microphone acquired. The electronic device control system 1 has a dynamic range of the microphone and / or a sound pressure or a sound pressure level in a range that can be extracted by the control signal extraction unit, a position in each region of each output unit, and / or each region. Based on information such as the position of an existing obstacle, the attenuation amount of the sound wave corresponding to the distance from the output unit in each region is acquired in advance. Then, the electronic device control system 1 outputs sound waves having a sound pressure or a sound pressure level adjusted according to the dynamic range of the microphone and / or the sound pressure or sound pressure level in a range that can be extracted by the control signal extraction unit. Output from each output unit. Thereby, the electronic device control system 1 can selectively output the sound wave converted from the specific control signal to the special region, and thus can control the operation of the electronic device for each region.

  Note that the electronic device according to the present embodiment stores disaster information such as a mobile information terminal 26 such as a smartphone, a mobile phone terminal, a tablet PC, and / or a mobile computer, a home appliance such as a television 28 or a radio, and an earthquake early warning.

  Next, details of the configuration of the electronic device control unit 10 will be described.

(Information acquisition unit 100)
The information acquisition unit 100 includes the operation designation information for designating the operation of the electronic device 20 and the electronic device 20 to be controlled, and the region selected from a plurality of regions (or from a range where a predetermined sound wave reaches). The selected area information indicating the selected area) is acquired. The information acquisition unit 100 also includes information on a plurality of areas in which the electronic device 20 controlled by the electronic device control system 1 may exist, for example, position information in each area of each output unit, output characteristics of each output unit (for example, Information indicating directivity and / or distortion rate) and / or information on acoustic environment of each region (for example, information indicating distance between output units, reflectance of sound wave by structure existing in each region) Information on the reflection direction and the sound absorption rate).

  Further, the information acquisition unit 100 is information related to the electronic device 20, for example, information indicating characteristics of the receiving unit 200 provided in each electronic device (for example, information indicating dynamic range, information indicating directivity), and / or control. The characteristic information of the signal extraction unit 210 (for example, information indicating the sound pressure or the sound pressure level that can be properly extracted by the control signal extraction unit 210) is acquired. Note that when the electronic device control system 1 further includes an information storage unit that stores information, and the information storage unit stores information in advance, the information acquisition unit 100 can also acquire information from the information storage unit. The information acquisition unit 100 can also acquire operation designation information, selection area information, information about a plurality of areas in which the electronic device 20 can exist, and the like from an external information recording medium. The information acquisition unit 100 supplies part or all of the acquired information to the control signal generation unit 110.

(Control signal generator 110)
The control signal generation unit 110 generates a control signal for selectively controlling the operation of an electronic device existing within a range where a predetermined sound wave reaches. Specifically, the control signal generation unit 110 generates a control signal for controlling the operation of the electronic device 20 based on the operation designation information and / or the selection area information. The control signal generation unit 110 generates a control signal in accordance with a predetermined method. The control signal generation unit 110 can also generate text data as a control signal by encoding characters in advance. The control signal generation unit 110 can also generate a control signal including a control identifier that uniquely identifies predetermined operation designation information. Furthermore, the control signal generation unit 110 can also generate a control signal including an instruction for causing the electronic device 20 to execute an operation corresponding to a time-series change in the signal intensity of the sound wave. The control signal generation unit 110 supplies the generated control signal and the information received from the information acquisition unit 100 to the signal conversion unit 120.

(Signal converter 120)
The signal conversion unit 120 converts the control signal received from the control signal generation unit 110 into an electric signal intended to be selectively transmitted as a sound wave to the electronic device 20. Specifically, the signal converter 120 has a sound pressure or a sound pressure level that is selectively transmitted to the electronic device 20 in the selected region, and generates a sound wave having a frequency that is difficult (or not perceived) by human hearing. Convert to convertible electrical signal. Here, the signal conversion unit 120 causes the control signal to correspond to the sound pressure or sound pressure level in the range that can be received by the receiving unit 200 or the sound pressure or sound pressure level in the range that can be extracted by the control signal extracting unit 210. The sound signal is converted into an electric signal that can be converted into a sound wave having a sound pressure or a sound pressure level.

  Specifically, the signal conversion unit 120 is output from the output unit of the selection region corresponding to the selection region information from the position information in each region of each output unit acquired by the information acquisition unit 100 and the output characteristics of each output unit. The amount of sound pressure or sound pressure level of the sound wave to be attenuated according to the distance from the output unit is grasped. Since the attenuation amount of the sound wave is determined according to the distance, the signal converter 120 determines how much the sound pressure or the sound pressure level of the sound wave output from the output unit 130 is attenuated according to the distance from the output unit 130. I can grasp it.

  Further, the signal converter 120 is configured to receive a sound pressure or a sound pressure level that can be received by the receiving unit 200 from the characteristic information of the receiving unit 200 or the control signal extracting unit 210 included in the electronic device 20 to be controlled by the electronic device control system 1. Or the range of the sound pressure or the sound pressure level that can be extracted by the control signal extraction unit 210. Then, the signal conversion unit 120 adjusts the sound pressure or the sound pressure level so that the sound wave reaches the selection area for the purpose of selectively controlling the operation of the electronic device 20 existing in the selection area.

  As an example, when a sound wave having a sound pressure level of X dB is output from the output unit 130 (where X> 0), the sound pressure level of the sound wave is at a point Zm away from the output unit 130 (where Z> 0). A case is assumed where the attenuation is YdB (where Y <X). In this case, if the receiving unit 200 included in the electronic device 20 cannot receive a sound wave having a sound pressure level equal to or lower than YdB, the selected region is a region having a radius less than Zm from the output unit 130. Therefore, the signal conversion unit 120 adjusts the sound pressure or the sound pressure level based on the selection region information indicating that the region having the radius less than Zm is the selection region from the output unit 130.

  Note that the signal conversion unit 120 can adjust the sound pressure or the sound pressure level so that it falls below the reception sensitivity threshold of the reception unit 200 or falls within the reception sensitivity range, or can be extracted by the control signal extraction unit 210. It is also possible to adjust so as to be within or out of the range of the appropriate sound pressure or sound pressure level.

  Further, the signal converter 120 converts the control signal received from the control signal generator 110 into an electrical signal that can be converted into a plurality of frequencies that are difficult to be perceived by human hearing or a plurality of sound waves that are not perceived by humans. You can also. Here, the frequency that is hard to perceive or not perceived by human hearing is, for example, a frequency around 18 kHz. For example, the signal conversion unit 120 can convert the control signal into an electrical signal that can be converted into a sound wave having a frequency of 16 kHz and a sound wave having a frequency of 18 kHz as a frequency that is difficult to perceive by human hearing or a frequency that is not perceived.

  The signal conversion unit 120 selects an output unit installed in the selection area corresponding to the selection area information. Then, the signal conversion unit 120 supplies an electrical signal to the selected output unit. In addition, when the signal conversion unit 120 converts the control signal into an electric signal that can be converted into a plurality of sound waves having a plurality of frequencies that are difficult (or not perceived) by human hearing, a modulation signal (for example, FM modulation signal) can also be added. As a result, the electronic device control system 1 can radiate FM modulated waves, which are less prone to errors due to noise, to the electronic device 20.

  The signal conversion unit 120 can also acquire the control signal from a recording medium in which the control signal is stored in advance and convert the control signal into an electrical signal intended to be selectively transmitted as a sound wave to the electronic device 20. . In this case, the recording medium can also store other information (for example, information such as music flowing in a facility such as an amusement park, video displayed on a large screen display unit, etc.) along with the control signal. The recording medium is, for example, an optical recording medium such as a CD or DVD, or a magnetic recording medium such as a hard disk drive.

(Output unit 130 to output unit 130x)

  The supply of information from the information acquisition unit 100 to the control signal generation unit 110 and / or the supply of information from the control signal generation unit 110 to the signal conversion unit 120 may be executed via a communication network such as the Internet. it can.

  Next, details of the configuration of the electronic device 20 will be described. The electronic device 20 according to the present embodiment only needs to include at least the reception unit 200, the control signal extraction unit 210, and the device control unit 220, and other components having various functions are appropriately added. be able to.

(Receiver 200)
The receiving unit 200 receives the sound wave output from the output unit 130. The receiving unit 200 is, for example, a microphone. The receiving unit 200 converts the received sound wave into an electric signal and supplies it to the control signal extracting unit 210 and / or the analyzing unit 250.

(Control signal extraction unit 210)
The control signal extraction unit 210 extracts the control signal generated by the control signal generation unit 110 from the sound wave received by the reception unit 200. Specifically, the control signal extraction unit 210 decodes and extracts a control signal from an electrical signal encoded based on a predetermined method. Note that the control signal extraction unit 210 can also extract text data when the control signal includes text data. The control signal extraction unit 210 supplies the extracted control signal and / or text data to the device control unit 220.

  The control signal generation unit 110 can also generate a control signal including a device identifier that identifies the electronic device 20. In this case, the control signal extraction unit 210 includes a device identifier (hereinafter referred to as “first device identifier”) associated with the electronic device 20 having the control signal extraction unit 210 and a device included in the extracted control signal. The identifier (hereinafter referred to as “second device identifier”) is compared. Then, the control signal extraction unit 210 supplies the control signal to the device control unit 220 when the first device identifier and the second device identifier match. On the other hand, if the first device identifier and the second device identifier do not match, the control signal extraction unit 210 waits without supplying a control signal to the device control unit 220. Here, the device identifier associated with the electronic device 20 is either a device identifier that is physically set using a jumper switch or the like, or a device identifier that is electromagnetically set by recording in advance in a predetermined memory. It may be.

(Device control unit 220)
The device control unit 220 executes an operation corresponding to the control signal received from the control signal extraction unit 210. For example, the device control unit 220 generates a predetermined command signal from the control signal. Then, the device control unit 220 causes the electronic device 20 to execute an operation associated with the command signal. For example, the electronic device 20 includes a power control unit that controls the power supply of the electronic device 20, a display unit that displays text data, a still image, and / or a moving image, an audio output unit that outputs audio, and predetermined light emission. A light emitting unit that emits light in color, a driving unit such as a vibrating unit that vibrates the electronic device 20, and / or a communication unit that controls communication between the electronic device 20 and the outside of the electronic device 20 by wired communication or wireless communication When some or all of them are included, the device control unit 220 controls the operation of some or all of these components according to the command signal.

(Execution information storage unit 230)
The execution information storage unit 230 stores execution information as operation designation information including a command signal for causing the electronic device 20 to execute a predetermined operation in association with a control identifier. When the control identifier is included in the control signal received from the control signal extraction unit 210, the device control unit 220 acquires the execution information stored in the execution information storage unit 230 in association with the control identifier. Then, the device control unit 220 causes the electronic device 20 to execute an operation corresponding to the execution information acquired from the execution information storage unit 230. Thereby, since the electronic device control system 1 can control the operation of the electronic device 20 only by causing the electronic device 20 to acquire a control identifier, sequential control of the operation of the electronic device 20 in time series can be omitted. Moreover, since the electronic device control system 1 can output a control signal including a different control identifier in each of the plurality of regions, the operation of the electronic device 20 can be made different for each of the plurality of regions.

(Execution information acquisition unit 240)
The execution information acquisition unit 240 acquires execution information from the outside in association with the control identifier. Specifically, the execution information acquisition unit 240 acquires execution information from the outside through an information recording medium, wired communication, or wireless communication. As an example, the execution information acquisition part 240 acquires execution information with a control identifier from the server which an amusement park has via the internet or radio | wireless communication. The execution information acquisition unit 240 stores the acquired execution information in the execution information storage unit 230 in association with the control identifier.

  In the modification of the present embodiment, execution information associated with a control identifier in advance can be stored in the execution information storage unit 230. In this case, the electronic device 20 may not have the execution information acquisition unit 240.

(Analysis unit 250)
The analysis unit 250 analyzes the change in the sound pressure or the sound pressure level of the sound wave received by the reception unit 200 that receives the sound wave output from the predetermined output unit 130. Specifically, the analysis unit 250 analyzes the sound pressure or the time series change of the sound pressure level. The analysis unit 250 supplies information indicating the analysis result (hereinafter referred to as “analysis information”) to the analysis result transmission unit 260.

(Analysis result transmission unit 260)
The analysis result transmission unit 260 transmits the analysis information received from the analysis unit 250 to the information acquisition unit 100 included in the electronic device control unit 10. The information acquisition unit 100 supplies the analysis information received from the analysis result transmission unit 260 to the control signal generation unit 110. The control signal generation unit 110 determines a change in the position of the electronic device 20 with respect to the predetermined output unit 130 based on the analysis information. Then, the control signal generation unit 110 generates a control signal corresponding to the change in position.

  For example, the control signal generation unit 110 generates different control signals depending on whether the electronic device 20 moves away from the predetermined output unit 130 or approaches. As an example, a case will be described in which the electronic device control system 1 is installed in a store having a plurality of areas (for example, a plurality of areas divided according to the types of products). In this case, it is assumed that the predetermined output unit 130 is installed such that the sound wave output from the predetermined output unit 130 installed in the predetermined area attenuates from the store toward the store entrance. Then, the control signal generation unit 110 of the electronic device control system 1 moves the electronic device 20 toward the inside of the store based on analysis information received from the electronic device 20 (for example, a portable information terminal) in a predetermined area. It is possible to determine whether it is moving or moving toward the outside of the store.

  When the control signal generation unit 110 determines that the electronic device 20 has moved to the outside of the store based on the determination result, the control signal generation unit 110 relates to a coupon that can be used when the electronic device 20 enters the store next time. Information can be generated as text data. Further, when it is determined that the electronic device 20 has moved to the inside of the store based on the determination result, the control signal generation unit 110 generates, as text data, information related to a coupon that can be used at the store on that day. Can do.

  Further, in the electronic device control system according to the modification of the first embodiment, the electronic device 20 can also execute an operation according to a time-series change in the signal intensity of the sound wave received by the receiving unit 200. Specifically, first, the control signal generation unit 110 generates a control signal including an instruction for causing the electronic device 20 to perform an operation corresponding to a time-series change in the signal intensity of the sound wave. For example, when the signal intensity of the sound wave attenuates, the control signal generation unit 110 includes a signal instructing acquisition of the first information stored in a predetermined server and the signal intensity of the sound wave increases. Generates a control signal including a signal instructing acquisition of second information stored in a predetermined server. The output unit 130 outputs a sound wave including the control signal. The server storing the first information and the server storing the second information may be the same server or different servers.

  When receiving the sound wave, the receiving unit 200 of the electronic device 20 converts the sound wave into an electric signal and supplies the electric signal to the analysis unit 250. The analysis unit 250 supplies the analysis information to the analysis result transmission unit 260. The analysis result transmission unit 260 supplies the analysis information received from the analysis unit 250 to the control signal extraction unit 210 instead of transmitting it to the information acquisition unit 100. Then, when receiving analysis information indicating that the signal intensity of the sound wave is attenuated, the control signal extraction unit 210 extracts a control signal including a signal instructing acquisition of the first information. On the other hand, when receiving the analysis information indicating that the signal intensity of the sound wave increases, the control signal extraction unit 210 extracts a control signal including a signal instructing acquisition of the second information.

  Subsequently, the device control unit 220 acquires the first information or the second information from a predetermined server according to the control signal extracted by the control signal extraction unit 210.

  FIG. 3 shows an example of an outline of the operation of the electronic device control system according to the first embodiment of the present invention.

  In FIG. 3, a case where the penlight 22 is used as the electronic device 20 is taken as an example. The penlight 22 includes a light emitting area 24 and a microphone 202 as a receiving unit. The light emitting region 24 emits light in a plurality of light emission colors (for example, red, yellow, blue, green, etc.). Similarly, the penlight 22a and the penlight 22b have a light emitting area 24a and a light emitting area 24b, and a microphone 202a and a microphone 202b, respectively. In FIG. 3, the penlight 22 exists in the area where the output unit 130a is installed, the penlight 22a exists in the area where the output unit 130b is installed, and the area where the output unit 130c is installed. Assume that the penlight 22b exists. That is, in the example of FIG. 3, penlights exist in each of the three areas.

  The electronic device control system 1 generates three types of control signals when the penlight 22 to the penlight 22b perform different operations. For example, the light emitting area 24 of the penlight 22 in the area where the output unit 130a is installed (that is, the first selection area) is caused to emit red light, and the area where the output unit 130b is installed (ie, the second selection area). Consider a case where the light emitting area 24a of the penlight 22a in the area) is caused to emit green light, and the light emitting area 24b of the penlight 22b in the area where the output unit 130c is installed (that is, the third selected area) is caused to emit blue light. .

  The control signal generator 110 generates a first control signal for the penlight 22 (that is, a control signal that causes the light emitting area 24 to emit red light) and a second control signal for the penlight 22a (that is, the light emitting area 24a changes to green). A control signal for emitting light) and a third control signal for the penlight 22b (that is, a control signal for causing the light emitting region 24b to emit blue light). The signal conversion unit 120 converts the first control signal into a sound wave having a predetermined sound pressure or a predetermined sound pressure level based on the first selection region information regarding the first selection region, the characteristic information of the microphone 202, and the like. To a first electrical signal. Similarly, the signal converter 120 converts the second control signal into a second electrical signal and converts the third control signal into a third electrical signal.

  A predetermined sound pressure (hereinafter referred to as “first sound pressure”) or a predetermined sound pressure level (hereinafter referred to as “first sound pressure level”) set by the signal conversion unit 120 with respect to the first control signal. Is a sound wave having a first sound pressure or a first sound pressure level in a region where the output unit 130a is installed, that is, in a first selection region defined by a predetermined radius around the output unit 130a. Is set so that only the electronic device 20 existing in the first selection region operates. The signal conversion unit 120 similarly sets the sound pressure or the sound pressure level for the second control signal and the third control signal.

  Next, the signal converter 120 supplies the first electrical signal to the output unit 130a based on the first selection region information, and outputs the second electrical signal based on the second selection region information to the output unit 130b. To supply. Similarly, the signal conversion unit 120 supplies the third electric signal to the output unit 130c based on the third selection region information. The output unit 130a outputs the first electric signal as the first sound wave 40, the output unit 130b outputs the second electric signal as the second sound wave 40a, and the output unit 130c outputs the third electric signal. It outputs as the 3rd sound wave 40b. Accordingly, the light emitting area 24 of the penlight 22 that has received the first sound wave 40 emits red light, the light emitting area 24a of the penlight 22a that has received the second sound wave 40a emits green light, and the third sound wave 40b. The light emitting area 24b of the penlight 22b that receives the light emits blue light.

  FIG. 4 shows another example of the outline of the operation of the electronic device control system according to the first embodiment of the present invention.

  FIG. 4 shows an example in which the penlight 22 is used as the electronic device 20 as in FIG. For example, when the electronic device control system 1 causes the penlight 22 and the penlight 22a to perform the same operation and does not cause the penlight 22b to operate, the electronic device control system 1 generates one type of control signal. As an example, the light emission region 24 of the penlight 22 existing in the first selection region and the light emission region 24a of the penlight 22a existing in the second selection region are caused to emit red light, and the penlight existing in the third selection region. Consider a case where the light emitting region 24b of 22b is not illuminated.

  The control signal generation unit 110 generates a first control signal for the penlight 22 and a second control signal for the penlight 22a. The signal conversion unit 120 converts the first control signal into a first electrical signal based on the first selection area information regarding the first selection area, the characteristic information of the microphone 202, and the like. Similarly, the signal converter 120 converts the second control signal into a second electric signal. Here, the signal conversion unit 120 is a first sound pressure that can be converted into a first sound pressure at which only the penlight 22 existing in the first selection region operates or a first sound wave at a first sound pressure level. The first control signal is converted into an electrical signal. Similarly, the signal conversion unit 120 is a second sound pressure that can be converted into a second sound pressure at which only the penlight 22a existing in the second selection region operates or a second sound wave at the second sound pressure level. The second control signal is converted into an electrical signal.

  Next, the signal converter 120 supplies the first electrical signal to the output unit 130a based on the first selection region information, and outputs the second electrical signal based on the second selection region information to the output unit 130b. To supply. On the other hand, the signal conversion unit 120 does not operate the penlight 22b in the third selection region, and therefore does not supply an electrical signal to the output unit 130c.

  Thereby, the output unit 130a outputs the first electric signal as the first sound wave 40, and the output unit 130b outputs the second electric signal as the second sound wave 40a. The light emitting area 24 of the penlight 22 that has received the first sound wave 40 emits red light, and the light emitting area 24a of the penlight 22a that has received the second sound wave 40a emits red light. On the other hand, the light emitting region 24b of the penlight 22b does not emit light because it does not receive sound waves from the output unit 130c.

(Outline of electronic device control method)
FIG. 5 shows an example of an outline of the processing flow of the electronic device control system according to the first embodiment of the present invention.

  First, the information acquisition unit 100 of the electronic device control system 1 causes the operation designation information, selection region information, and a plurality of regions where the electronic device 20 can exist (that is, a sound wave having a predetermined sound pressure or sound pressure level arrives). Information within the range to be acquired (step 10; hereinafter, step is represented as “S”). The information acquisition unit 100 supplies the acquired information to the control signal generation unit 110. The control signal generation unit 110 generates a control signal for controlling the operation of the electronic device 20 existing in the predetermined area based on the operation designation information and the selection area information (S20). The control signal generation unit 110 supplies the generated control signal to the signal conversion unit 120.

  The signal conversion unit 120 adjusts the sound pressure or the sound pressure level that is selectively transmitted to the electronic device 20 in the selection area corresponding to the selection area information, and then the frequency (or is not perceived by human hearing). The control signal received from the control signal generation unit 110 is converted into an electric signal that can be converted into a sound wave having a frequency (S30). The signal conversion unit 120 supplies the electric signal to the output unit 130 installed in the selection area corresponding to the selection area information. The output unit 130 converts the electrical signal into a sound wave and outputs it to the outside (S40).

  The receiving unit 200 included in the electronic device 20 receives the sound wave output from the output unit 130 (S50). The receiving unit 200 supplies the received sound wave to the control signal extracting unit 210. The control signal extraction unit 210 extracts a control signal from the sound wave (S60). The control signal extraction unit 210 supplies the extracted control signal to the device control unit 220. The device control unit 220 controls the operation of the electronic device 20 based on the control signal extracted by the control signal extraction unit 210 (S70).

  FIG. 6 shows an example of an outline of a functional configuration of the control signal extraction unit according to the first embodiment of the present invention.

  The electronic device control system 1 includes a plurality of output units 130. Therefore, the distance between one output unit 130 and another output unit 130 is such that one sound wave output from one output unit 130 interferes with another sound wave output from another output unit 130. It can be a distance to get. In this case, the control signal extraction unit 210 extracts either a control signal included in one sound wave or a control signal included in another sound wave based on the signal intensity of one sound wave and the signal intensity of another sound wave. Decide what to do. When the electronic device 20 has a plurality of receiving units (for example, when the receiving unit 200 is a stereo microphone), the control signal extracting unit 210 receives the signal intensity of one sound wave received by the left microphone and the right microphone. It is also possible to determine which one of the control signal contained in one sound wave and the control signal contained in the other sound wave is to be extracted based on the signal intensity of the other sound wave received by.

  Specifically, the control signal extraction unit 210 analyzes an electric signal based on the analysis result of the electric signal analysis unit 212 and the electric signal analysis unit 212 that analyzes the signal strength of the electric signal converted from the sound wave received by the reception unit 200. A signal strength determining unit 214 that determines the strength of the signal strength, and a signal extracting unit 216 that extracts a control signal based on the determination result of the signal strength determining unit 214.

  The electrical signal analysis unit 212 determines whether a plurality of electrical signals are received from the reception unit 200. When the electrical signal analysis unit 212 receives a plurality of electrical signals from the reception unit 200, the electrical signal analysis unit 212 analyzes the signal strength of the control signal included in each electrical signal. The electrical signal analysis unit 212 is, for example, a technique for analyzing, separating, and extracting a signal having a specific frequency band from sound waves output from the plurality of output units 130, such as a Fourier transform processing technique and / or a bandpass filter technique. Analysis processing is executed by using. Subsequently, the electrical signal analysis unit 212 supplies the analysis result to the signal strength determination unit 214.

  The signal strength determination unit 214 compares a plurality of signal strengths. Then, the signal strength determining unit 214 determines that the electrical signal to be extracted has the strongest signal strength, the weakest signal strength, or a predetermined signal strength. The signal strength of the electrical signal that the signal strength judgment unit 214 judges to be an electrical signal to be extracted is preferably the strongest signal strength from the viewpoint of facilitating selection of the electrical signal. The signal strength determination unit 214 supplies the determination result to the signal extraction unit 216.

  The signal extraction unit 216 selects one electrical signal from a plurality of electrical signals based on the determination result of the signal strength determination unit 214, and then extracts a control signal from the selected one electrical signal. When the electric signal analyzing unit 212 receives a single electric signal from the receiving unit 200 (that is, when there is no mixture of a plurality of sound waves), the electric signal analyzing unit 212 uses the electric signal received from the receiving unit 200 as it is. The signal is supplied to the signal extraction unit 216. Then, the signal extraction unit 216 extracts a control signal from the electrical signal received from the electrical signal analysis unit 212. The signal extraction unit 216 supplies the extracted control signal to the device control unit 220. The device control unit 220 causes the electronic device 20 to execute an operation corresponding to the control signal received from the signal extraction unit 216.

(Effects of the first embodiment)
The electronic device control system 1 according to the first embodiment adjusts the sound pressure or the sound pressure level from each of the plurality of output units 130 so as to reach a predetermined region, and then includes a sound wave including a control signal. For example, concert halls, amusement parks, stadiums, auditoriums, arenas, shopping streets, or commercial facilities, etc. Timing can be selectively controlled.

  In addition, the electronic device control system 1 according to the present embodiment includes the reception unit 200 and / or the control signal extraction unit 210 in which the electronic device 20 has the sound pressure or sound pressure level of the sound wave output from the output unit 130 such as a speaker. Since sound waves are output according to the characteristics, existing sound output devices can be used as they are. Thereby, according to the electronic device control system 1, the cost of capital investment can be suppressed. Furthermore, the electronic device control system 1 uses a sound wave having a frequency that is difficult to be perceived by human hearing (or a frequency that is not perceived) as a carrier wave of the control signal. It can also be transmitted synchronously or superimposed.

  The electronic device control system 1 can convert a control signal including text data into a sound wave and transmit it to the electronic device 20. Therefore, according to the electronic device control system 1, for example, when the electronic device 20 is a portable information terminal such as a smartphone, the portable information terminal is within a predetermined area defined in the electronic device control system 1 (for example, a storefront of a store). Etc.), information related to the area (for example, coupon information of the store, URL information of the store, information about bargains at the store, etc.) can be output to the mobile information terminal in real time.

  Moreover, the electronic device control system 1 can generate different control signals for each of a plurality of predetermined areas.

(Second Embodiment)
In the electronic device control system 1a according to the second embodiment of the present invention, the electronic device control unit 10 is mounted on a moving vehicle in which a traveling sound such as an electric vehicle or a hybrid car is difficult to be heard by a pedestrian, and the vehicle is traveling on a road. Except for the point that a pedestrian and / or a passerby riding a bicycle or motorcycle carries a portable information terminal as the electronic device 20, the configuration is substantially the same as the electronic device control system 1 according to the first embodiment. And has a function. Therefore, a detailed description is omitted except for differences. For convenience of explanation, in the following explanation, a case where a pedestrian is carrying a portable information terminal will be explained.

  The electronic device control unit 10 mounted on the moving vehicle is a control signal that causes the portable information terminal to execute a predetermined operation in the front, rear, and / or side direction of the moving vehicle while the moving vehicle is traveling. A sound wave containing is emitted. The electronic device control unit 10 radiates sound waves by adjusting the sound pressure or sound pressure level of the sound waves so that the sound waves reach a predetermined distance from the moving vehicle. Note that the electronic device control unit 10 can emit sound waves including different control signals in the front, rear, and side directions of the moving vehicle.

  The execution information storage unit 230 of the portable information terminal carried by the pedestrian stores in advance execution information for executing a specific operation in accordance with a specific control signal received from the moving vehicle. For example, when the receiving unit 200 receives a sound wave including a predetermined control signal from the electronic device control unit 10 of the moving vehicle, the execution information storage unit 230 displays a warning indicating that the moving vehicle is approaching. Execution information to be output perceptually is stored in advance.

  Further, the electronic device control unit 10 calculates a change in the distance between the mobile information terminal and the moving vehicle based on the functions of the analysis unit 250 and the analysis result transmission unit 260 included in the mobile information terminal. And the electronic device control unit 10 is a case where the moving vehicle is approaching the portable information terminal, the moving vehicle is moving away from the portable information terminal, and / or between the portable information terminal and the moving vehicle. A sound wave including a control signal for causing the portable information terminal to output different warning information is emitted according to each of cases where the distance is within or outside the predetermined distance range. Furthermore, the electronic device control unit 10 radiates sound waves including different control signals according to the difference in the distance between the moving vehicle and the portable information terminal in the front, rear, and side directions of the moving vehicle. You can also.

  Thereby, according to the electronic device control system 1a, even when a moving vehicle with a quiet running sound approaches the pedestrian, the pedestrian can be warned of the approach of the moving vehicle, so traffic accidents can be reduced. Also, according to the electronic device control system 1a, sound waves including different control signals can be radiated in the front, rear, and side directions of the moving vehicle. Therefore, according to the position of the portable information terminal existing around the moving vehicle. A control signal including different warning information can be supplied to the portable information terminal.

  Furthermore, the electronic device control unit 10 of the electronic device control system 1a can be mounted on a normal vehicle (for example, an election vehicle, a street vehicle, a business vehicle, or the like) that is not a moving vehicle in which the traveling sound is difficult for a pedestrian to hear. In this case, the electronic device control unit 10 can appropriately change information to be output to the portable information terminal carried by the pedestrian by adjusting the sound pressure or sound pressure level emitted from the vehicle into the atmosphere.

  For example, a case where the vehicle is an election vehicle will be described. When the distance between the election vehicle and the portable information terminal is equal to or greater than a predetermined distance, that is, the sound pressure level of the sound wave received by the receiving unit 200 of the portable information terminal from the electronic device control unit 10 is predetermined. When the analysis unit 250 analyzes that the pressure level is equal to or lower than the pressure level, the electronic device control unit 10 supplies a control signal including text data representing a candidate profile of the election to the portable information terminal. On the other hand, when the analysis unit 250 analyzes that the sound pressure level of the sound wave received by the reception unit 200 exceeds a predetermined sound pressure level, the electronic device control unit 10 complements the speech content of the candidate. A control signal including text data is supplied to the portable information terminal.

  In the electronic device control system 1a according to the modification of the second embodiment, information corresponding to the signal intensity of the sound wave received by the receiving unit 200 can be supplied to the portable information terminal.

  For example, when the signal intensity of the sound wave is equal to or higher than a predetermined intensity, the control signal generation unit 110 includes first information relating to a predetermined server (as an example, details of the election candidate's manifest are described. If the signal intensity of the sound wave is less than a predetermined intensity, the predetermined server includes the second information regarding the storage (for example, the profile of the candidate for election). A control signal including a signal instructing acquisition of the URL) is generated. The output unit 130 outputs a sound wave including the control signal. The server storing the first information and the server storing the second information may be the same server or different servers.

  When receiving the sound wave, the receiving unit 200 of the portable information terminal converts the sound wave into an electric signal and supplies the electric signal to the analysis unit 250. The analysis unit 250 supplies the analysis information to the analysis result transmission unit 260. The analysis result transmission unit 260 supplies the analysis information received from the analysis unit 250 to the control signal extraction unit 210. And control signal extraction part 210 extracts a control signal containing a signal which instruct | indicates acquisition of 1st information, when the analysis information which shows the signal intensity of a sound wave more than a predetermined intensity is received. On the other hand, when receiving analysis information indicating that the signal intensity of the sound wave is less than a predetermined intensity, the control signal extraction unit 210 extracts a control signal including a signal instructing acquisition of the second information. Subsequently, the device control unit 220 acquires the first information or the second information from a predetermined server according to the control signal extracted by the control signal extraction unit 210.

  Thereby, according to the electronic device control system 1a, the information to be output to the portable information terminal can be appropriately changed according to the distance between the election vehicle and the portable information terminal. In addition, according to the electronic device control system 1a, different control signals can be supplied to the front, rear, and side directions of the election vehicle, so that the mobile information terminal carried by the people surrounding the election vehicle depends on the position of the election vehicle. Different control signals can be supplied to the portable information terminal. Furthermore, according to the electronic device control system 1a, for example, when an election vehicle that outputs a sound wave concentrically is stopped, an instruction to acquire different information is given based on the signal intensity of the sound wave (that is, the absolute intensity of the sound wave). A control signal including a signal to be transmitted can be supplied to the portable information terminal.

  The location information acquisition unit acquires location information when the disaster prevention information application receives information on disaster prevention (for example, earthquake bulletin, tsunami bulletin, etc.) from the disaster prevention information center. And a portable information terminal transmits the positional information which the positional information acquisition part acquired to the disaster prevention information center. The electronic device control unit 10 installed in the disaster prevention information center acquires position information from each of a plurality of portable information terminals. Here, the electronic device control unit 10 can acquire position information of the portable information terminal in association with a terminal identifier that uniquely identifies the portable information terminal. Next, the electronic device control unit 10 has an optimum disaster prevention for each of a plurality of areas, for each of a plurality of positions indicated by the plurality of position information or for each of a plurality of areas including each of the plurality of positions indicated by the plurality of position information.

Thereby, according to the electronic device control system 1b, the most appropriate disaster prevention information can be selected for each region where the portable information terminal exists, and a control signal including the selected disaster prevention information can be supplied to each of the portable information terminals. .

  In addition, when the electronic device control unit 10 emits a sound wave including a control signal in an area where the portable information terminal is present, the electronic device control unit 10 can also emit a start signal for starting the television included in the sound wave. In this case, the control signal extraction unit 210 of the portable information terminal extracts the control signal and the activation signal from the sound wave. Then, when the device control unit 220 acquires the control signal and the activation signal from the control signal extraction unit 210, the device control unit 220 causes the portable information terminal to perform an operation corresponding to the control signal and transmits the activation signal to the television to to start. Thereby, according to the electronic device control system 1b, even when the TV existing around the portable information terminal is turned off at the time of the disaster, the TV can be automatically started, Even residents can quickly get information about disasters by viewing TV.
