Description

【Technical Field】 【0001】 The present disclosure relates to an acoustic system that arranges and uses a plurality of speakers in a facility. 【Background Art】 【0002】 There is known a system that connects a plurality of speakers to a computer via a network for centralized management (see, for example, Patent Document 1). In recent years, in offices, attempts have been made to play music by arranging a plurality of speakers in order to improve work efficiency and achieve a relaxation effect. Here, music includes various types, such as music pieces like JPOP or classical music, or those that record natural sounds such as the sound of flowing river water or the chirping of birds. 【0003】 In an office, there are various spaces such as conference rooms, rest rooms, cafeterias, reception rooms, and private rooms. In particular, in a shared office, a public space used by many people and a private space used by specific users coexist. In such a complex environment, it is difficult to provide an optimal acoustic environment for many people. Since each person has their own likes and dislikes and preferences, if individuals can freely set their respective audio devices, it is not necessarily a comfortable acoustic environment for others. For example, problems such as playing music at a high volume only for one person or playing music that is not suitable for the occasion only for one person may occur. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2020-95064 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 The present disclosure is an acoustic system that can manage a plurality of speakers arranged in various spaces of a facility and provide an optimal music environment. [Means for solving the problem] 【0006】 The sound system disclosed herein is a sound system used in a facility having a public space accessible to multiple users and one or more private spaces accessible to a limited number of users. A speaker installed in the aforementioned facility, comprising one or more first speakers installed in the public space and one or more second speakers installed in the private space, and The system includes a management server connected to the speaker, which identifies and manages whether each speaker is located in the public space or the private space, The management server creates a first web page that allows operation instructions to be issued to the first speaker and the second speaker, and The management server creates a second web page that allows user terminals outside the management server to issue control instructions to the second speaker. 【0007】 The computer program disclosed herein is a computer program for controlling speakers located in a facility having a public space accessible to multiple users and one or more private spaces accessible to restricted users. The speaker includes one or more first speakers placed in the public space and one or more second speakers placed in the private space. The computer program generates a first web page that allows an administrator terminal to issue control instructions to the first speaker and the second speaker, and a second web page that allows a user terminal of a user using a private space to issue control instructions to the second speaker located in that private space. [Effects of the Invention] 【0008】 The sound system of this disclosure comprises a plurality of speakers placed in a facility and a management server connected to the plurality of speakers. The management server provides the administrator with a first web page that allows them to control all speakers, and a second web page that allows each private space user to control only the speakers located in their space. Therefore, the administrator can provide a harmonious musical environment throughout the facility, and each private space user can customize the musical environment of their private space to their liking.

First Embodiment (1) Configuration of the audio system 1 according to the first embodiment As shown in FIG. 1, the audio system 1 of this embodiment includes a plurality of speakers 10 arranged in a facility, a management server 20, and an administrator terminal 22. Here, the facility can be various, such as an office, a factory, a government office, a public facility, a commercial facility such as a department store, a stadium, a concert hall, a hotel, etc. 【0011】 The facility in this embodiment includes a public space and a private space. The public space is, in principle, a space that can be used by all users of the facility. For example, a reception area, a coffee corner, a lounge corner, etc. The private space is a space that can be used only by restricted users among the users of the facility. For example, a meeting room, a reception room, a private room used by one or more users alone, etc. The private space may be a space reserved and used by the user of that space at a specific time. 【0012】 Speaker 10 is connected to the management server 20 via a network. Speaker 10 is an IP speaker. Speaker 10 comprises a communication unit 11, a storage unit 12, a playback unit 13, and a control unit 14. The communication unit 11 is connected to the network, communicates with the network, and receives commands from the management server 20. The storage unit 12 stores one or more songs. Songs include, for example, J-POP and classical music, as well as recordings of natural sounds such as the sound of flowing water or birdsong. The playback unit 13 amplifies and plays the music. The control unit 14 selects a song stored in the storage unit 12 according to a command received by the communication unit 11, and instructs the playback unit 13 to amplify and play the song at the volume specified in the command. In this embodiment, the songs are stored in the storage unit 12 of speaker 10, but they may be stored in another location. For example, they may be provided by the management server 20. 【0013】 The speaker 10 includes speakers placed in public spaces (sometimes referred to as the first speaker 10a) and speakers placed in private spaces (sometimes referred to as the second speaker 10b). 【0014】 The speaker 10 may be a directional speaker 10A that emits sound in a specific direction, or an omnidirectional speaker 10B that emits sound in multiple directions within the horizontal plane. Examples of directional speakers 10A include wall-mounted speakers, desktop speakers, and floor-standing speakers. Examples of omnidirectional speakers 10B include ceiling-mounted speakers, desktop speakers, and floor-standing speakers. 【0015】 An IP speaker is assigned a unique identifier (e.g., an IP address) that identifies it on network N. Speaker 10 does not have to be an IP speaker; it may also be connected to the network via a communication device. During voice calls, the IP speaker transmits and receives voice and video data in accordance with IP calling protocols. One example of an IP calling protocol is SIP (Session Initiation Protocol), which was standardized by the IETF (Internet Engineering Task Force) and specified in RFC 3261. 【0016】 The speaker 10 and the management server 20 are configured on a LAN (Local Area Network) and interconnected. The administrator terminal 22 and the user terminal 24 are connected to the management server 20 on the LAN. The network may consist of multiple LANs and a WAN (Wide Area Network) such as the Internet that interconnects them. The speaker 10 is connected to a router that constitutes the LAN via an Ethernet cable, and transmits voice data via the Ethernet cable. It may also be powered via PoE (Power over Ethernet) via the Ethernet cable. Note that the network used in this embodiment does not have to consist entirely of LANs, WANs, etc. For example, the user terminal 24 may be configured to connect from a public telephone line to the LAN to which the management server 20 belongs. 【0017】 The management server 20 is connected to multiple speakers 10 within the facility via a network. The management server 20 identifies and manages whether each speaker 10 is located in a public space or a private space. The management server 20 is a computer and includes a processor and a memory unit. The memory unit stores a program that controls the speakers 10. The processor reads and executes the program stored in the memory unit, sending commands to each speaker 10 to specify the music to be played and the volume at which the music is played. 【0018】 (2) Speaker control method for sound system 1 This section describes the speaker control method for sound system 1. 【0019】 The management server 20 knows the locations of the speakers 10 connected to the network within the facility. An example of a speaker information table stored in the management server 20's memory is shown in Figure 3 (Table 1). In Figure 3 (Table 1), the first column lists the name (or number) of each speaker, and the second column shows the location of each speaker. The third column indicates whether the location is a public space or a private space. In other words, the management server 20 identifies and manages whether each speaker 10 is located in a public space or a private space. 【0020】 The management server 20 stores the speaker control program in its memory along with a speaker information table as shown in Table 1. The speaker control program includes two types of web pages for inputting user operation commands for the speakers 10. The web pages are written using HTML (HyperText Markedup Language). The first web page allows the administrator of the sound system 1 to issue operation commands for the speakers 10. All speakers 10 can be operated using the first web page. The hostname and path name portion of the URL (Uniform Resource Locator) address of the first web page (hereinafter abbreviated as URL address) is, for example, xxx.jp / admin as shown in Table 1. The second web page allows users' terminals 24 using the private space to issue operation commands for the second speaker 10b located in that private space. In principle, a second web page is created for each speaker 10. In this embodiment, a second web page is created for each second speaker 10b, and the number of second web pages is the same as the number of second speakers 10b. In Table 1, the URL address for the second webpage for speaker 03 is xxx.jp / spk03, and the URL address for the second webpage for speaker 04 is xxx.jp / spk04. 【0021】 (2-1) Administrator enters operational instructions for the first web page. The administrator uses a browser on the administrator terminal 22 to launch the speaker control program stored on the management server 20 and access the first web page. By entering operation instructions on the first web page, commands can be created for all the speakers 10 in the facility. 【0022】 An example of the operation instruction input screen 51 for the first webpage is shown in Figure 4. In the first line of the input screen 51 in Figure 4, you can select the speaker 10 to input the operation command from among all the speakers 10 in the facility. In Figure 4, "Cafe Corner 1," which is the first speaker 10a located in the public space, is selected. 【0023】 On the operation instruction input screen 51 of the first webpage, the items that can be controlled are displayed from the second line onwards for the speaker 10 selected on the first line. The controllable items here are the sound source (second line), volume (third line), and playback period (fourth to fifth lines). The sound source refers to what kind of music will be played on each speaker. The sound source is selected from the list of songs that will pop up on the second line. Songs include, for example, J-POP and classical music, as well as recordings of natural sounds such as the sound of flowing water or birdsong. In Figure 4, "J-POP Song 1" is selected. The volume is set so that, for example, the volume gradually increases from level 1 to level 10. On the operation instruction input screen 51, the volume can be selected by the administrator. In Figure 4, "Level 3" is selected. 【0024】 The playback period for speaker 10 can be set in the 4th to 5th rows of screen 51 in Figure 4. Screen 51 shows that on March 11th, speaker 10 in "Cafe Corner 1" was set to play from 9:00 to 10:00. 【0025】 Furthermore, the first webpage may have a screen 52 that displays a timetable showing what settings have been made for each speaker 10, or the status of the settings being made, as shown in Figure 5. 【0026】 In screen 51 of Figure 4, after entering the playback conditions for speaker 10, click "OK" on the 6th line to finish inputting. Clicking "OK" may also be designed to execute an operation instruction (command) for speaker "Cafe Corner 1". Click "Cancel" to start the input process again from the beginning. 【0027】 As described above, once the input of the operation instruction for speaker "Cafe Corner 1" is complete on the operation instruction input screen 51, the next speaker 10 is selected and the operation instruction input (command creation) is performed. Once the input has been completed for all speakers to which operation instructions are to be performed, the administrator may stop the input. 【0028】 The speaker control program, or the first web page, may further include a map (layout display screen 53) showing the placement of speakers 10 within the facility. Figures 6A and 6B are examples of the layout display screen 53. Figure 6A is a display screen on the first web page, and Figure 6B shows the symbols of the speakers 10 placed in the facility. In the display screen 53 of Figure 6B, the speakers 10 are distinguished and displayed as directional speakers 10Aa placed in public spaces, omnidirectional speakers 10Ba placed in public spaces, and directional speakers 10Ab placed in private spaces. Although not displayed in the display screen 53 of Figures 6A and 6B, omnidirectional speakers 10Bb placed in private spaces may also be included. 【0029】 When the first webpage is accessed, a layout display screen 53 of the speaker 10, as shown in Figure 6A, may be displayed on the display screen of the terminal 24. Then, by clicking on a specific speaker 10Aa, 10Ba, 10Ab, or 10Bb from the display screen 53, a settings screen as shown in Figure 4 may be displayed. In Figure 6A, a mark indicating that the speaker 11b of the selected "Café Corner 1" is selected is displayed. 【0030】 In addition, the speaker layout display screen 53, as shown in Figure 6A, may be displayed simultaneously with the playback schedule for each speaker, as shown in Figure 4 (Figure 7). 【0031】 Furthermore, by selecting a specific speaker 10 on the layout map shown in Figure 6A, the settings screen for the selected speaker 11b may be superimposed on the front (Figure 8). 【0032】 (2-2) Input of operation instructions to the second webpage by users of the private space Next, we will explain how users of the private space can input information into the second webpage. 【0033】 As a preliminary step, the management server uses a speaker information table and a speaker control program to issue a 2D barcode for each speaker 10. A 2D barcode may be issued for each private space. The 2D barcode is, for example, a QR code (registered trademark). Each 2D barcode is printed on paper and placed in the private space. Alternatively, the 2D barcode is displayed on digital signage in the private space. Users of the private space use their devices to read the 2D barcode and access a second webpage corresponding to the speaker 10 installed in the private space. 【0034】 The management server 20 may separately manage reservations for the use of private spaces. In this case, the management server 20 checks the ID of the terminal attempting to access the second webpage, and if it determines that the terminal belongs to the user or is associated with the user, it grants the user's terminal access to the second webpage. 【0035】 An example of the operation instruction input screen 55 of the second web page is shown in FIG. 9. The first line of the operation instruction input screen indicates the speaker 10 to be operated. The difference between the operation instruction input screen 51 for administrators (see FIG. 4) and the operation instruction input screen 55 for private space users (FIG. 9) is that the former can select and input the speaker 10 for the operation instruction input symmetry, while the latter inputs for the speaker 10 that has been specified in advance. The operation instruction items available for the second line and below are common to both. The operation instruction items available for the operation instruction input screen of the second web page are the sound source (second line), volume (third line), and playback period (lines 4-5), similar to the first web page. Regarding the playback period, the management server 20 may check the reservation of the private space and limit the speaker usage period only to the usage period of the private space user's room. Note that the operation instruction items available for the operation instruction input screen of the second web page may be more restricted than those of the operation instruction input screen of the first web page. For example, while the volume level from 1 to 5 steps can be operationally instructed from the operation instruction input screen of the first web page, the volume level from 1 to 3 steps may be configured to be operationally instructed from the operation instruction input screen of the second web page. For example, while it is possible to operationally instruct the selection of a desired sound source from X sound sources from the operation instruction input screen of the first web page, it may be configured to be possible to operationally instruct the selection of a desired sound source from Y sound sources (Y < X) from the operation instruction input screen of the second web page. 【0036】 (2-3) Execution of music playback in each speaker 10 Next, an overview of the music playback process using the audio system 1 of the present embodiment will be described with reference to FIGS. 10 and 11. 【0037】 The administrator terminal 22 and the user terminal 24 use a browser to launch the speaker control program stored on the management server and access the first or second web page. The administrator or user of the private space enters operation instructions while viewing the display screen of the first or second web page. The administrator terminal 22 or the user terminal 24 accepts GUI (Graphical User Interface) operation input. The operation instructions are sent to the management server 20 as shown in Figure 10, and the management server 20 receives the operation instructions. Based on the received content, the management server 20 creates a command for the speaker 10. The management server 20 sends the command to the speaker 10. The communication unit 11 of the speaker 10 receives the command. Based on the received command, the speaker 10 changes the music playback settings and controls playback. 【0038】 Furthermore, Figure 11 shows the control flow of the speaker 10 by the management server 20, taking into account the playback reservation time (period). When the playback start time entered on the first or second web page arrives, the management server 20 sends a music playback command to the speaker 10. Upon receiving the command, the speaker 10 starts playing music. When the playback end time entered on the first or second web page arrives, the management server 20 sends a music playback end command to the speaker 10. Upon receiving the command, the speaker 10 stops playing music. 【0039】 (3) Modified Embodiment 1A In the first embodiment, the management server 20 managed reservations for the facility's private spaces. In modified embodiment 1A, as shown in Figure 12, the management server 20 is connected to the facility reservation server 30 via a network. The facility reservation server 30 manages reservations for the facility's private spaces. The other configurations of modified embodiment 1A are the same as in the first embodiment. 【0040】 When a user's terminal accesses the second webpage of the management server 20, the management server 20 checks the reservation status of the private space corresponding to that second webpage with the facility reservation server 30. The facility reservation server 30 stores facility reservation information, which records the reservation status of that private space, in its storage unit. When the facility reservation server 30 receives an inquiry from the management server 20, it sends the facility reservation information for that private space to the management server 20. Upon receiving the facility reservation information, the management server 20 allows terminal 24 to access the second webpage if it is the terminal 24 of the facility reservation holder or a terminal 24 related to the facility reservation holder, but does not allow terminal 24 to access the second webpage if it is not the terminal 24 of the facility reservation holder or a terminal 24 related to the facility reservation holder. 【0041】 Furthermore, when a user terminal 24 that has been granted access to the second webpage configures its speaker usage settings, the management server 20 may restrict the usage time (period) setting to within the reservation time range of the private space facility reservation information. 【0042】 (4) Modified Embodiment 1B In the first embodiment, one speaker 1b is placed in each private space. In the modified embodiment 1B, two or more speakers 1b are placed in one or more private spaces. In this case, a second web page corresponding to a private room in which multiple speakers 1b are placed is generated for each private space, and each second web page may be configured to allow operation instructions for multiple speakers 1b in the corresponding private space. Alternatively, the system may be configured to generate a second web page for each of the multiple speakers 1b placed in the same private space. 【0043】 2. Second Embodiment In the first embodiment of the sound system 1, facility users other than the administrator could not issue control commands to the first speaker 10a located in the public space using a web page. In the second embodiment, facility users other than the administrator can also issue control commands to the first speaker 10a located in the public space using a web page. This web page will be referred to as the third web page. However, in the third web page, the range of items that facility users other than the administrator can control the first speaker 10a is more limited than the range of items that the administrator can control the first speaker 10a is limited in the first web page. 【0044】 The speaker information table in the second embodiment is shown in Figure 13 (Table 2). In Figure 13 (Table 2), the first column lists the name (or number) of each speaker, and the second column shows the installation location of each speaker. The third column indicates whether the installation location is a public space or a private space. In other words, in this embodiment as well, the management server 20 identifies and manages whether each speaker 10 is located in a public space or a private space. 【0045】 Similar to the first embodiment, in this embodiment as well, the management server 20 stores the speaker control program in its storage unit along with the speaker information table shown in Table 2. The speaker control program includes three types of web pages for inputting usage operations for the speaker 10. The web pages are written using HTML. 【0046】 The first webpage is identical to that of the first embodiment and is a webpage from which the administrator of the sound system 1 can issue operating instructions for the speakers 10. All speakers 10 can be operated from the first webpage. The URL address of the first webpage is, for example, xxx.jp / admin, as shown in Table 1. 【0047】 The second webpage, as in the first embodiment, is a webpage that allows users to issue operational instructions to the second speaker 10b from their terminal 24 using the private space. In principle, a second webpage is created for each second speaker 10b. The number of second webpages is the same as the number of second speakers 10b. In Table 2, the URL address of the second webpage for speaker 03 is xxx.jp / spk03, and the URL address of the second webpage for speaker 04 is xxx.jp / spk04. 【0048】 The third webpage is a webpage that allows users of the public space to send operational instructions to the first speaker 10a from their terminal 24. In principle, a third webpage is created for each first speaker 10a. The number of third webpages is the same as the number of first speakers 10a. In Table 2, the URL address of the third webpage for speaker 01 is xxx.jp / spk01, and the URL address of the third webpage for speaker 02 is xxx.jp / spk02. 【0049】 The input of operational instructions to the first webpage by the administrator, and the input of operational instructions to the second webpage by users of the private space, are exactly the same as in the first embodiment, so we will omit the explanation. 【0050】 This section describes how facility users can input operational instructions for the third webpage of the first speaker 10a located in the public space. 【0051】 Users of the public space search for the 2D barcode of the first speaker 10a they wish to use within the public space. Once the 2D barcode is found, scanning it allows access to the third web page for each first speaker 10a on the management server 20, where they can input operating instructions for that first speaker 10a on a screen 55 as shown in Figure 9. 【0052】 However, in this case, as illustrated in Figures 14 and 15, the settings for the operation instructions of the first speaker 10a on the third webpage are more restricted than those on the first webpage. Figure 14 (Table 3) shows the input restrictions for setting operation instructions for each user on the second webpage. Figure 15 (Table 4) shows the input restrictions for setting operation instructions on the first webpage for administrators. As is clear from the comparison of Tables 3 and 4, on the third webpage in Table 3, sound source selection is prohibited and volume settings are limited to levels 1 to 5 for "Speaker 01" and "Speaker 02" located in the public space. On the other hand, on the first webpage in Table 4, sound source selection is permitted for "Speaker 01" to "Speaker 04," and a wide range of volume settings from levels 1 to 10 is allowed. 【0053】 Tables 3 and 4 show that the user's input of operation instructions for the first speaker 10a on the third webpage is subject to greater restrictions in both sound source selection and volume setting compared to the administrator's input of operation instructions for the first speaker 10a on the first webpage. The system may be configured to impose greater restrictions in either sound source selection or volume setting. 【0054】 The configuration of the other aspects of the second embodiment is the same as that of the first embodiment. Similar to modified embodiment 1A, it is also possible to use the facility reservation server 30 in combination with the sound system 1 of the second embodiment. Furthermore, similar to modified embodiment 1B, it may be configured to generate a common second web page for multiple speakers 1b located in the same private space. 【0055】 3. Features of the First and Second Embodiments The sound system 1 is a sound system that controls multiple speakers 10 placed in a facility. The facility has a public space that can be used by multiple users and one or more private spaces that can be used by restricted users. The sound system 1 comprises multiple speakers 10 and a management server 20. The management server 20 and each speaker 10 are connected via a network. The speakers 10 include one or more first speakers 10a placed in the public space and one or more second speakers 10b placed in the private space. The management server 20 executes a speaker control program to control music playback of the speakers 10. 【0056】 The speaker control program includes a first webpage for administrator input and a second webpage for users of the private space. The first webpage allows input of operation commands for the first speaker 10a and the second speaker. The second webpage allows input of operation commands for a specific second speaker. The operation command input items include sound source selection, volume setting, and playback period. 【0057】 The administrator can connect to the first web page using the administrator terminal 22. The administrator terminal 22 is connected to the management server 20 via the network. 【0058】 The user terminal 24 is configured to connect to the management server 20 via the network.
