  Next, the operation of the first embodiment of the present invention will be described.

  FIG. 4 is a flowchart for explaining the operation of the server apparatus 10 in the first embodiment shown in FIG. The process of this flowchart is a process executed by the server device 10 when the user who has purchased the viewing device operates the client device 30 to access the server device 10. In addition, the user inputs information for identifying the viewing device (for example, product model number) or uses the user by selecting the corresponding product from the displayed product group. Access the page corresponding to the viewing device.

  Step S10: The CPU 10a acquires information corresponding to the viewing device owned by the user from the GUI image data 10d1 of the HDD 10d, and transmits the information to the client device 30 via the I / F 10f. As a result, in the client device 30, the CPU 30a receives this information via the I / F 30f and supplies it to the video circuit 30e. The video circuit 30e executes a drawing process based on the information supplied from the CPU 30a, converts the obtained image data into a video signal, and supplies the video signal to the display device 30h. As a result, a GUI image for inputting environment information as shown in FIG. 5 is displayed on the display device 30h.

  In this display example, “viewing room support system” is displayed as the title 51 at the top of the frame 50 constituting the GUI image. Below that, an acknowledgment for the purchase of the product by the user and a message 52 prompting the user to answer the question are displayed.

  Below that, questions 53 to 56 and text boxes 57 to 60 are displayed as question 1. Here, the question 53 is a question asking the type of room, and is selected from a Japanese-style room, a Western-style room (with a carpet), and a Western-style room (without a carpet). In the text box 57 next to the question 53, a number corresponding to a desired limb is input from these three options. The question 54 is a question asking about the size of the room, and is selected from 4.5 tatami mats, 6 tatami mats, 8 tatami mats, 10 tatami mats, 12 tatami mats, 15 tatami mats, and 20 tatami mats. In the text box 58 next to the question 54, a number corresponding to a desired limb is input from these seven options.

  The question 55 is a question asking about the height of the ceiling, and is selected from 2 m, 2.3 m, 2.5 m, 2.7 m, 3 m, 3.5 m, and 4 m. A number corresponding to a desired limb is input from the seven options to a text box 59 on the right side of the question 55. The question 56 is a question asking about the position of the window, and the corresponding one is selected from nine illustrations displayed below. In each of the nine illustrations, hatched portions indicate windows. In the text box 60 next to the question 56, a number corresponding to a desired limb is input from these nine options.

  Step S11: The CPU 10a determines whether or not the input has been completed in the GUI image shown in FIG. 5, and proceeds to step S12 if it has been completed, and repeats the same processing otherwise.

  Step S12: The CPU 10a acquires information input in the GUI image shown in FIG. 5, performs a simulation based on the simulation program 10d2, and determines an optimal arrangement of the speakers. In the simulation, the type of viewing device purchased by the user is referred to in addition to the information on the type of room, the size of the room, the height of the ceiling, and the position of the window shown in FIG. More specifically, the frequency band in which a standing wave is generated is calculated by referring to the room type, area, ceiling height, window position, etc., and the vibration attenuation rate depends on the flooring material. To obtain the acoustic characteristics of the room.

  Step S13: The CPU 10a acquires corresponding information from the advice information 10d3 based on the result of the simulation in step S12, and presents information indicating the speaker arrangement to the client device 30. That is, the advice information that advises the optimal arrangement of the viewing device with respect to the acoustic characteristics obtained by the simulation is selected and transmitted to the client device 30. The client device 30 receives the information and displays it on the display device 30h. FIG. 6 is a diagram illustrating an example of a GUI image displayed on the display device 30 h of the client device 30 at this time. In this example, “viewing room support system” is displayed as the title 71 at the top of the frame 70 constituting the GUI image. Below that, there is displayed a message 72 that prompts the user to input the speaker arrangement similar to the illustration 74 shown below as question 3 and whether or not the viewing position can be selected. A text box 73 for inputting an answer to the question 3 is displayed on the right side of the message. Below that, an illustration 74 showing the recommended speaker placement position and viewing position is displayed.

  Step S14: The CPU 10a determines whether or not it has been input that the arrangement of the speakers and the viewing position shown in FIG. 6 can be selected, and if the input is possible, the process proceeds to Step S17. The process proceeds to step S15. For example, as shown in FIG. 6, if it is input in the text box 73 as impossible, the process proceeds to step S15.

  Step S15: The CPU 10a refers to the advice information 10d3, and refers to the room type, room size, ceiling height, and window position input in FIG. (However, the arrangement and viewing position of the speaker presented in step S13 are excluded) and transmitted to the client device 30 for display. FIG. 7 is a diagram illustrating an example of information displayed on the display device 30h of the client device 30 at this time.

  In this display example, “viewing support system” is displayed as the title 81 at the top of the frame 80 constituting the GUI image. Below that, a message 82 is displayed prompting the user to input a position where the speaker can be arranged in the user's room, and a text box 83 for inputting the selected number is displayed to the right of the message 82. Below that, four illustrations 84 indicating the positions of the speakers are displayed. In such a GUI image, for example, when the number “2” is input to the text box 83, the CPU 10a acquires information indicating that the second arrangement state has been selected.

  Step S16: The CPU 10a executes a simulation according to the arrangement state selected in FIG. 7 based on the simulation program 10d2. This simulation is the same as in step S12.

  Step S17: The CPU 10a causes the client device 30 to display an expected sound tendency on the basis of the simulation in step S12 or the simulation in step S16. FIG. 8 is a diagram illustrating an example of a graph indicating the tendency of the sound displayed on the client device 30 at this time. In this figure, the horizontal axis indicates the frequency, and the vertical axis indicates the gain, indicating the sound pressure characteristics at the viewing position at each frequency. In this example, the characteristics in the range of 50 Hz to 5 kHz are shown. However, the characteristics of 2 kHz or more are not so high in calculation accuracy and require calculation time, so that the calculation is limited to 2 kHz or less. You may do it. In that case, accurate results can be obtained in a short time.

  In addition to the graph shown in FIG. 8, the tendency of sound may be displayed as text, for example. For example, “It seems that the low range is fully reproducible up to the deep bass. The mid range has a slight variation in the frequency response, so the vocal may be slightly blurred. The high range is the sound from the window. May cause phase shift. It is thought that this is suitable for JAZZ playback. "

  Step S18: The CPU 10a confirms whether or not the client device 30 accepts the tendency of the sound displayed in Step S17, that is, whether or not the sound tendency is satisfied, and does not accept it. In step S19, otherwise, the process ends.

  Step S19: The CPU 10a reads predetermined information from the GUI image data 10d1 stored in the HDD 10d, transmits it to the client device 30 via the I / F 10f, and generates a GUI image for inputting an ideal sound tendency. The data is displayed on the display device 30 h of the client device 30.

  FIG. 9 is a diagram illustrating an example of a GUI image displayed on the display device 30h of the client device 30 at this time. In this display example, “viewing room support system” is displayed as the title at the top of the frame 90 constituting the GUI image. Below that, questions 92 to 96 relating to the tendency of sound are displayed, and text boxes 97 to 101 for inputting numbers relating to options of each question are displayed to the right of each question.

  Specifically, in the question 92, the tendency of the desired sound in the low tone is selected from “open” and “shut down”. In the question 93, the tendency of the vocal sound is selected from “protruding to the front” and “merging into the whole”. In the question 94, the favorite music genre is selected from “JAZZ”, “Classic”, “Pops”, “Rap”, “Reggae”, “Kyokyoku”, “Easy Listening”, and “Namikyoku”. In question 95, the favorite movie genre is selected from “action”, “thriller”, “romance”, and “comedy”. In the question 96, the normal set sound volume is selected from “large”, “medium”, and “small”.

  Step S20: The CPU 10a determines whether or not the input to the GUI image shown in FIG. 9 has been completed in the client device 30, and proceeds to step S21 if completed, and repeats the same processing otherwise.

  Step S21: The CPU 10a reads predetermined information from the advice information 10d3 for giving advice on furniture and soundproofing material based on the information input in the GUI image shown in FIG. Upon receiving the advice information 10d3, the client device 30 displays it on the display device 30h. Here, furniture refers to sofas, beds, living boards, figurines, curtains, and the like. The soundproofing material is a material that is made of a material having a high sound absorption characteristic and is installed in a viewing room where it is desired to prevent reflection of sound.

  Specifically, for example, in FIG. 9, when “Rough” is selected for the tendency of a low-pitched sound, advice for making a flat low-frequency characteristic is selected. In addition, when “Shit” is selected, advice that emphasizes about 80 Hz is selected. When “Fukuyoka” is selected for the tendency of medium sounds, advice for making the characteristic emphasized at 500 Hz is selected. Further, when “clear” is selected, the advice that emphasizes 5 kHz to 8 kHz is selected. When “protruding to the front” is selected for the tendency of the vocal sound, advice with a characteristic in which the midrange is emphasized is selected. In addition, when “incorporate into the whole” is selected, advice that gives a flat characteristic as a whole is selected. For example, when “JAZZ” is selected as the favorite music, advice that gives a characteristic in which the low sound range and the high sound range are emphasized is selected. When “Classic” is selected, advice is selected that results in an overall flat characteristic. When “pops” is selected, advice having a characteristic in which the mid-range, which is a vocal band, is emphasized is selected. In addition, when “action” or “thriller” is selected in a favorite movie, advice for selecting a characteristic that emphasizes the low frequency range is selected in order to obtain a more powerful sound. When “romance” or “comedy” is selected, advice is selected that emphasizes the midrange, which is the vocal band. As for the volume, advice for soundproofing according to the selected volume is selected.

  In addition, about each furniture, the magnitude | size and sound absorption performance are registered previously, the arrangement position in a room is determined in consideration of how much sound of which frequency band can be attenuated, and it displays as advice.

  FIG. 10 is a diagram illustrating an example of a GUI image displayed on the display device 30h of the client device 30 at this time. In this display example, “viewing room support system” is displayed as the title 121 at the top of the frame 120 constituting the GUI image. Also, “Improved points of customer's viewing room” is displayed as a message 122 below. Below that, an illustration 123 indicating an improvement point is displayed. At the bottom, a message 124 explaining the improvement point is displayed. Specifically, in this display example, in order to prevent reflection of sound from the window, it is advised that a vocal is projected to the front by arranging a sound insulation curtain on the window. It should be noted that the character string “sound insulation curtain” constituting the message 124 is underlined and indicates that a link is provided in this portion. Note that information stored in the web information 10d4 is used as information for establishing a link.

  Step S22: The CPU 10a determines whether or not the user has selected information on the presented furniture, soundproofing material, etc. in the GUI image shown in FIG. 10 by operating the input device 30i. The process proceeds to S23, and otherwise the process is terminated. Specifically, when the input device 30i shown in FIG. 10 is operated and the underlined character string “sound insulation curtain” is designated, the process proceeds to step S23.

  Note that the processing in step S22 may be determined by the CPU 30a of the client device 30 instead of the server device 10.

  Step S23: The CPU 11a (not shown) of the server device 11 which is the link destination of the underlined character string “sound insulation curtain” shown in FIG. 10 reads predetermined information from the HDD 11d (not shown), / F11f to client device 30. As a result, a GUI image (web page information) as shown in FIG. 11 is displayed on the client device 30.

  In this display example, “viewing room support system” is displayed as the title 131 at the top of the frame 130 constituting the GUI image. Below that, a “sound insulation curtain that matches the customer's system” is displayed as a message 132. Below that, an image group 133 showing six types of sound insulation curtains is displayed. In addition, the kind of sound insulation curtain shown in FIG. 11 is selected in consideration of the following points. That is, first, the sound insulation curtain needs to have sound insulation performance (frequency characteristics and attenuation characteristics) calculated based on the tendency of the ideal sound input in FIG. Moreover, it is necessary to be a sound insulation curtain having design uniformity with the viewing device purchased by the user. In FIG. 11, a sound insulation curtain that satisfies these conditions is selected and displayed as a candidate.

  Step S24: The CPU 11a determines whether or not an operation for purchasing a predetermined product has been performed on the GUI image shown in FIG. 11, and if so, the process proceeds to step S25, and otherwise the process ends.

  Step S25: In the GUI image shown in FIG. 11, when a purchase procedure is performed, first, a process for designating a shipping destination and the like is performed between the server apparatus 11 and then managed by a bank or a credit card company. Processing related to payment of a price is executed with the server device 12. As a result, the product purchase process is completed.

  FIG. 14 is a diagram illustrating a configuration example of the viewing device 160. As shown in this figure, the viewing device 160 includes a CPU 160a, ROM 160b, RAM 160c, control unit 160d, bus 160e, I / F 160f, amplifier unit 160g, input device 160i, and microphone 160j.

  Here, the CPU 160a is an arithmetic device that executes various processes based on information stored in the ROM 160b. The ROM 160b is a semiconductor storage device that stores a basic program executed by the CPU 160a. The RAM 160b is a semiconductor memory device that temporarily stores data and programs when the CPU 160a executes various arithmetic processes. The control unit 160d controls the amplifier unit 160g based on the control of the CPU 160a. For example, the amplifier unit 160g performs an equalizer process on an audio signal from various sound sources (for example, a CD (Compact Disk) or the like), amplifies the signal with a predetermined gain, and supplies the amplified signal to a speaker (not shown).

  The bus 160e is a signal line group that connects the CPU 160a, the ROM 160b, the RAM 160c, the control unit 160d, and the I / F 160f to each other and enables information exchange between them. The I / F 160f converts the representation format of the information output from the input device 160i and sends it to the bus 160e, and also converts the representation format when exchanging information with the client device 30. The analog signal output from the microphone 160j is converted into a digital signal and input. Specifically, the client device 30 and the viewing device 160 are connected by, for example, a USB (Universal Serial Bus) or the like. The microphone 160j is a device for converting sound into an electrical signal when measuring acoustic characteristics.

  Next, the operation of the second exemplary embodiment of the present invention will be described.

  FIG. 15 is a flowchart for explaining the operation of the second exemplary embodiment of the present invention. When the processing of the flowchart shown in this figure is started, the following steps are executed.

  Step S50: The CPU 150a of the server apparatus 150 that has received an access from the client apparatus 30 reads predetermined information from the GUI image data 150d1 of the HDD 150d and transmits it to the client apparatus 30 via the I / F 150f. As a result, a GUI image similar to that shown in FIG. 5 is displayed on the display device 30 h of the client device 30.

  Step S51: The CPU 150a determines whether or not the input of information with respect to the GUI image is finished. If finished, the process proceeds to step S52, and otherwise the same process is repeated.

  Step S52: The CPU 150a as the measurement unit reads the measurement data 150d2 from the HDD 150d and transmits it to the client device 30 via the I / F 150f. In the client device 30, the CPU 30a receives this information via the I / F 30f as output means and conversion means, and supplies it to the viewing device 160 via the I / F 30f. The viewing device 160 receives this information via the I / F 160f. Based on this information, the CPU 160a controls the control unit 160d, outputs a signal for measuring the acoustic characteristic to the amplifier unit 160g, and analyzes the information input from the microphone 160j, thereby determining the acoustic characteristic. taking measurement. Note that the microphone 160j is installed at a viewing point, for example, and collects sound at the position of the user's ear and converts it into an electrical signal.

  As a measurement method, for example, data for generating pink noise is supplied to the viewing device 160, and an audio signal from the microphone 160j is converted into digital data (compressed as necessary). Transmit to device 150. The server device 150 applies an octave bandpass filter to the received audio data, and measures frequency characteristics from the obtained output signal level. In addition, a single pulse signal is supplied to the viewing device 160, and an audio signal from the microphone 160j is converted into digital data and transmitted to the server device 150. The server device 150 measures the phase shift of the multichannel speaker and the presence / absence of multipath distortion by measuring the phase shift of the pulse and the reflected wave.

  Step S53: The CPU 150a transmits the measurement result data to the client device 30 and displays it on the display device 30h. As a result, a graph as shown in FIG. 8 is displayed on the display device 30 h of the client device 30. In addition to this, a graph regarding phase shift may be displayed.

  Step S54: The CPU 150a refers to the measurement result of the acoustic characteristic in step S52, and executes a process of automatically setting the characteristic of the viewing device 160 based on the setting data 150d3.

Thereby, the gain of the frequency corresponding to the peak is lowered, and the gain of the frequency corresponding to the valley is increased. As for the pulse response, the control unit 160d can set the delay amount of the delay circuit included in the amplifier unit 160g, for example, to correct the phase difference between the speakers in the case of multi-channel.

  Step S55: The CPU 150a transmits predetermined music data or environmental sound data (for example, sound data such as a human voice, rain sound, river noise) to the client device 30. The client device 30 supplies the received data to the viewing device 160 for reproduction. As a result, the user can view with the adjusted viewing device 160.

  Step S56: The CPU 150a determines whether or not the user approves the viewing result. If the user approves, the process ends. Otherwise, the process proceeds to step S57. For example, the CPU 150a reads predetermined information from the GUI image data 150d1, displays a GUI image (not shown) for confirming whether or not the display device 30h of the client device 30 has approved, and has the approval? Confirm whether or not.

  Step S57: The CPU 150a displays a GUI image as shown in FIG. 9 on the display device 30h of the client device 30.

  Step S58: The CPU 150a determines whether or not the input has been completed in the GUI image shown in FIG. 9. If it is determined that the input has been completed, the process proceeds to step S59, and otherwise the same process is repeated.

  Step S59: The CPU 150a refers to the preference of the sound input in the GUI image shown in FIG. 9, the information input in Step S50, and the acoustic characteristic measurement result in Step S52, and based on the setting data 150d3. Thus, the viewing device 160 is set via the client device 30 so that the desired characteristics are obtained. Specifically, as described above, when listening to JAZZ in preference, the gains of the low and high frequencies are set higher. In the case of a classic, the overall characteristics are adjusted to be flat.

  Step S60: The CPU 150a transmits predetermined music data or environmental sound data to the client device 30. The client device 30 supplies the received data to the viewing device 160 for reproduction. As a result, the user can view music or video with the viewing device 160 whose frequency characteristics and phase characteristics are appropriately adjusted.

  Step S61: As in the case of step S56, the CPU 150a determines whether or not the user approves the viewing result (adjustment result). If the user approves, the process is terminated. Otherwise, the process proceeds to step S62. Proceed to

  Step S62: The CPU 150a reads predetermined information from the advice information 150d4, displays a GUI image as shown in FIG. 10 on the display device 30h of the client device 30, and gives advice regarding furniture or soundproofing materials.

  Step S63: When the underlined character string “sound insulation curtain” is operated in the GUI image shown in FIG. 10, for example, the CPU 150a proceeds to Step S64. In addition, when the link corresponding to the “sound insulation curtain” is provided, information stored in the web information 150d5 is used.

  As in the case described above, the CPU 30a of the client device 30 may determine the process of step S63 instead of the server device 150.

  Step S64: The CPU 11a (not shown) of the server device 11 which is the link destination of the underlined character string “sound insulation curtain” shown in FIG. 10 reads predetermined information from the HDD 11d (not shown), / F11f to client device 30. As a result, a GUI image as shown in FIG. 11 is displayed on the client device 30.

  Step S65: The CPU 11a determines whether or not an operation for purchasing a predetermined product has been performed on the GUI image shown in FIG. 11, and if so, the process proceeds to step S66, and otherwise the process ends.

  Step S66: In the GUI image shown in FIG. 11, when a purchase procedure is performed, first, processing for designating a shipping destination and the like is performed with the server device 11, and then managed by a bank or a credit card company. Processing related to payment of a price is executed with the server device 12.
