Description

The present disclosure relates to an acoustic control system that outputs sound.

In recent years, ABW (Activity Based Working) offices have emerged as a result of work style reforms. This is a space design that improves the performance of the organization by preparing a space suitable for the activity content of the worker, such as solo work where one person concentrates on work and group work where multiple people share ideas. Methodology. On the other hand, a means for partitioning a space with a booth-type fixture or the like for the purpose of forming a concentrated space or the like for intensive work is known (Patent Document 1).

By the way, in ABW, the number of workers who want to use the concentrated space for intensive work is fluid depending on the time zone, day, week, and month, but if there are not enough concentrated booths, the needs of the workers cannot be met, and conversely. If there is a surplus, there is a problem that the space utilization efficiency of the entire office is lowered. However, according to known means for creating a centralized space such as a centralized booth, since the centralized booth is heavy and has a large volume, it is difficult to increase or decrease the number of concentrated spaces according to such fluidity.

Japanese Unexamined Patent Publication No. 2017-131572

Active zoning, which changes the layout of the space in a relatively short time (for example, instantaneously), uses speakers to control the type and volume of sound content provided by the speakers in order to flexibly respond to the needs of workers. It is conceivable that this will be realized (not known at the time of filing the application).

Here, in recent offices, instead of constructing speakers and lights embedded in the ceiling wall, a means for flexibly changing them by using duct rails is preferably selected. In this case, it is preferable that the control device for controlling the speaker and the lighting is a wireless connection.

In such a background, Bluetooth® communication can be mentioned as a wireless control means for a speaker that is often used these days. However, in the application of active zoning, for example, it is necessary to use four or five speakers, and at most ten or more speakers, and the present inventor continuously transmits sound information using Bluetooth communication. In the method, in office use, there are many Wi-Fi (registered trademark) radio waves and people in business PCs and OA equipment, so wireless communication is likely to be mixed and the sound is cut off significantly. We found a new one by a test using a set of acoustic control systems actually constructed using Bluetooth communication, and newly discovered that it is difficult to apply Bluetooth communication to active zoning using sound.

Therefore, an object of the present disclosure is to provide an acoustic control system capable of active zoning using sound contents and also suppressing sound interruption.

In order to solve the above problems, the acoustic control system according to the present disclosure includes two or more speaker systems that provide sound to the space, and a control system that transmits a control signal to each speaker system. A speaker element unit for outputting sound, a content storage unit for storing sound content data, a content control unit for executing one or more operations related to sound content, and a speaker radio for receiving wireless control signals. The control system includes a signal receiving unit and a power supply unit, and the control system includes a control condition storage unit that stores information about control conditions of each speaker system, a radio signal transmitting unit for a control system for transmitting a wireless control signal, and the like. The content control unit reads out the sound content data stored in the content storage unit based on the wireless control signal received by the wireless signal receiving unit for the speaker, and causes the speaker element unit to output the sound based on the sound content data. One or more controls including sound output control, and the control system outputs a radio control signal from the control system radio signal transmitter so that operations related to sound content are executed at the same time for a plurality of speaker systems at the same time. Perform one or more controls, including control.

According to the acoustic control system according to the present disclosure, since the speaker system that outputs sound has a content storage unit that stores sound content data, it is not necessary to continuously transmit sound content data in order to reproduce the content. .. Therefore, it is possible to realize a special and remarkable effect that the sound interruption can be substantially prevented even if the active zoning using the sound content is executed in the office use or the like.

It is a drawing which shows the example of the layout of the arrangement of the plurality of work desks possible in the ABW office as an example of the room where the acoustic control system which concerns on one Example of this disclosure is installed, and looks at a plurality of work desks from above. The layout of the desk and the layout of the base light mounted on the ceiling of the ABW office, the duct rail for energization, the task light, and the layout of multiple speaker systems mounted on the duct rail are superimposed on the layout of the work desk. It is a description layout layout drawing. It is a table which shows an example of a plurality of scenes which can be reproduced by the said acoustic control system. It is a block diagram which shows the main structure of the said acoustic control system. It is a table which shows one test result of the sound interruption / sound deviation generation test.

Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. When a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that a new embodiment is constructed by appropriately combining the characteristic portions thereof. Further, in the following examples, the same components are designated by the same reference numerals in the drawings, and duplicate description will be omitted. Further, among the components described below, the components not described in the independent claims indicating the highest level concept are arbitrary components and are not essential components.

FIG. 1 is a drawing showing an embodiment of a layout of a plurality of work desks D01 to D14 possible in an ABW office 20 as an example of a room in which an acoustic control system 10 according to an embodiment of the present disclosure is installed. , Arrangement when a plurality of work desks D01 to D14 are viewed from above, and a base light 73 attached to the ceiling of the ABW office 20, a duct rail 4 for energization, a task light 75, and a duct rail 4. FIG. 5 is a layout layout drawing in which layout drawings of a plurality of speaker systems 50a to 50d are superimposed on the layout of work desks D01 to D14.

As shown in FIG. 1, in one form of the ABW office 20, a total of 14 work desks D01 to D14, which are general office desks, are classified into desk group 1 and desk group 2, and above that, ABW Twenty-eight LED dimming toning base lights 73 (for example, NNLK41515 + NNL4600EXDK9: Panasonic) as ambient lighting for illuminating the office 20 are installed at equal intervals, and three rows of duct rails 4 for energization are installed in the vicinity thereof. Installed for a minute. Specifically, a total of 14 work desks D01 to D14 are arranged in four rows, and three duct rails 4 for energization are placed in the vicinity of three rows of work desks D01 to D14 among the four rows of work desks D01 to D14. They were arranged so as to extend in a direction substantially parallel to the extending direction of the row.

Further, four first to fourth speaker systems 50a to 50d were attached to the duct rail 4, and each speaker system 50a to 50d was wirelessly stereo-connected. In this embodiment, each speaker system 50a to 50d is configured by using LSPX-103E26 (Sony), but the speaker system may use any other sound output unit. Further, the first speaker system 50a and the second speaker system 50b form the speaker group 1, and the third speaker system 50c and the fourth speaker system 50d form the speaker group 2. Then, the first and second speaker systems 50a and 50b belonging to the speaker group 1 output the same first audio content, and the third and fourth speaker systems 50c and 50d belonging to the speaker group 2 have the same second sound content. Changed to output audio content.

The first and second speaker systems 50a and 50b belonging to the speaker group 1 output sound to a person existing in the area of the desk group 1, and the third and fourth speaker systems 50c and 50d belonging to the speaker group 2 output sound. , Outputs sound to people in the area of desk group 2. The number of speaker systems belonging to the speaker group 1 may be any number, and the number of speaker systems belonging to the speaker group 2 may be any number. Further, the speaker system 50 may be configured by using a directional speaker, for example, a parametric speaker or the like. Since ultrasonic waves are used in the parametric speaker, it is possible to give a remarkable directivity to the sound output direction.

Furthermore, a total of 14 task lights 75 were installed on each duct rail 4. The task light 75 was composed of an LED dimmable spotlight (for example, NTS05121W: Panasonic). At the same time, a wavelength conversion filter was attached to the opening of each task light 75, and the color temperature of the output light from the task light 75 was adjusted to 6000K. Then, a total of 14 work desks D01 to D14 and a total of 14 task lights 75 are made to correspond one-to-one, and each task light 75 illuminates the central portion of the corresponding work desks D01 to D14. The installation position and installation direction of the task light 75 were adjusted.

The 28 base lights 73 and the 14 task lights 75 include a multi-manager (for example, NQ51101: Panasonic), an LS / PD signal conversion interface (for example, NK51111: Panasonic), and a PD / dimming signal conversion interface (for example). , NK51012: Panasonic), PiPit + Separate Cercon A type (for example, NQ23171Z: Panasonic) were sequentially connected via a dimming signal line. In addition, 7 task lights 75 were paired with 2 PiPit + separate celcon A type prepared.

In such a configuration, in the acoustic control system 10 of the present disclosure, a speaker system 50, a base light 73, and a task light 75 are used by a person to cover a part of the area of the ABW office 20 from both sides of sound and illumination light. While making it an excellent centralized control area where it is easy to concentrate on work, the other part of the ABW office 20 is an excellent non-concentration area where people can feel particularly relaxed and multiple people can communicate with each other. The control area (co-creation area) is used, and the two areas are divided and zoned. In the following, first, the outline of the method for realizing zoning in two regions will be described from the viewpoint of sound and the viewpoint of illumination light with reference to FIG. 1 and FIG. 2 described later.

[1. Zoning using sound]
As will be described in detail later, each speaker system 50 has a content storage unit, and a plurality of sound content data are stored in the content storage unit. The plurality of sound contents include sound content data in which the sound of the babbling of a stream is recorded and sound content data in which the music of jazz or bossanova is recorded.

In such a background, a wireless control signal for reproducing the sound content of Ogawa's murmuring is transmitted from an information terminal, for example, a tablet, a smartphone, a personal computer, etc., to the speaker group 1 at the top of the desk group 1 via the multi-manager, and the speaker. The speaker systems 50a and 50b belonging to group 1 were made to reproduce the content of the babbling of a stream.

At the same time, from the above information terminal, a wireless control signal for reproducing sound content recorded with jazz or bossanova music is transmitted to the speaker group 2 via the multi-manager and transmitted to the speaker group 2 above the desk group 2. The sound contents recorded with jazz and bossanova music were reproduced in the speaker systems 50c and 50d belonging to the speaker group 2.

As a result, when I was seated at a desk belonging to Desk Group 1, I could hear the babbling sound of a stream, and I could only hear a little jazz and bossa nova music. On the other hand, when I was seated at the desk belonging to Desk Group 2, I could hear jazz bossa nova music, and I could only hear the babbling sound of the stream. From the above, it was confirmed that, for example, with such a configuration, different contents can be selectively provided to some extent in different desk group units. That is, the desk group 1 and the desk group 2 can be clearly spatially divided by outputting different sound contents between the desk group 1 and the desk group 2. Moreover, as described above, when the babbling sound of a stream is played by the desk group 1 and the jazz bossa nova music is played by the desk group 2, people can concentrate on the area of the desk group 1 to perform the work. The space control area for intensive work can be created, and the area of desk group 2 can be used as a space control area for non-centralized work (co-creation space) where people can easily feel relaxed and smooth communication by multiple people can be promoted.

The sound reproduction by the speaker groups 1 and 2 was performed by reproducing the scene by setting the scene in advance. Specifically, in the content storage unit of each speaker system 50, a plurality of scenes and sound contents to be reproduced in each scene are paired (in a state of being linked) and stored in advance. FIG. 2 is a table showing an example of a plurality of scenes that can be reproduced by the acoustic control system 10. In the example shown in FIG. 2, the acoustic control system 10 can reproduce four scenes. In the example shown in FIG. 2, when the scene 1 is reproduced, the babbling sound of a stream is output from the speaker group 1, and the sound content in which jazz or bossa nova music is recorded is output from the speaker group 2.

The babbling sound of a stream is close to the characteristics of so-called white noise and brown noise, which have intensity in the entire frequency range. This characteristic is a graph of the Fourier transform spectrum that has no intensity in the entire frequency domain when represented graphically as a frequency-to-intensity Fourier transform spectrum, for example, the frequency-to-intensity Fourier transform spectrum of a specific pitch sound of a piano. In comparison with the graph of, it can be mentioned that the frequency characteristic of the sound in the graph is broad. Sounds with this characteristic are noises that can reduce the efficiency of concentrated work that has various frequencies and is outpatient from a place other than desk group 1, as compared to sounds that tend to have no intensity in the frequency domain, for example. It has a remarkable effect of easily canceling noise, speaking voice, and the like. Therefore, workers working in desk group 1 are less likely to hear external noise. Therefore, the zone of the desk group 1 can be made into an area where the worker can easily concentrate on the work and can easily concentrate on the work. That is, it has the effect of enhancing the effect of the centralized control region in the present disclosure.

As sound content that can improve the efficiency of concentrated work, content close to the above-mentioned characteristics called white noise and brown noise is preferable, but this is not particularly limited. For example, it may be mainly composed of natural environment sounds such as the chirping sound of a small bird, the rubbing sound of forest leaves, and the sound of waves in the sea, or it is music composed mainly of electronic sounds whose waveforms are synthesized by a music synthesizer or the like. Is also good. The sound content may be a recorded natural sound as it is, may be composed by a human being, or may be composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the above various sounds.

On the other hand, in the existing area of the desk group 2, when the scene 1 is reproduced, the sound content in which the music of jazz or bossa nova is recorded is output from the speaker group 2. Compared to the above-mentioned white noise and brown noise, jazz bossa nova music has a characteristic that the frequency characteristic of sound in the graph of the Fourier transform spectrum of frequency vs. intensity is not broad. This is because instruments such as piano, saxophone, and bass, which mainly play jazz and bossanova, play a specific single scale, that is, de re mi fa so la si do and its chromatic scale. This is due to the fact that it is used in a state where it is strictly tuned to output. Therefore, the above-mentioned noise canceling function for external noise tends to be poor, but there is little need for the noise canceling function in a co-creation space that is intended to relax and communicate with multiple people in the first place. However, even if the noise canceling function is poor, no major adverse effect will occur.

Furthermore, jazz and bossa nova are preferred sound contents in cafes and relaxation facilities, and are frequently used to promote relaxation and smooth communication among multiple people. Therefore, as is clear from this, by using these sound contents, the worker can feel a sense of relaxation and comfort, and smooth communication can be realized.

From this, when the scene 1 is reproduced, the area of the desk group 1 can be used as the centralized work space control area, and the area of the desk group 2 can be used as the non-medium work space control area (co-creation space). It is preferable to adopt sound contents having characteristics similar to those called jazz or bossa nova as sound contents that can promote a feeling of relaxation and smooth communication by a plurality of people, but this is not particularly limited. For example, classical music, healing music, natural environment sounds, and the like may be adopted as sound contents that can promote a feeling of relaxation and smooth communication by a plurality of people. Such sound content may be a recorded natural sound as it is, may be composed by a human being, or may be composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the above various sounds.

From the above, it was confirmed that the zoning effect can be realized by using the sound content without using furniture or furniture. Here, the zoning effect means, for example, a cognitive sense of division of space, and may include an effect in which it is easy for a person to perceive that a plurality of spaces are certainly different spaces in appearance. Alternatively, the recognition may include the effect of facilitating changes in the behavior and flow lines of the worker as intended by zoning. For example, when zoning is intended for a concentrated space, the main purpose is for the worker who sees it to perform the concentrated work, and the effect is such that the space is used. Alternatively, it may include a subjective effect when the worker actually uses those spaces for the purpose, and an effect in which the physiological, psychological, and biological actions tend to show a tendency according to the purpose. For example, in zoning intended for a concentrated space, when a worker uses that place, he / she can feel that he / she was able to concentrate, or indicators / data suggesting that he / she was concentrating as a psychobiological effect. Is to be obtained. An office space with a high zoning effect is suitable as an ABW office in which the worker himself selects a space having a different design purpose in response to the worker's own emotional and motivated intentions. As for the zoning effect, the larger the difference in the sound volume and content of each group, the easier it is to enhance the effect. According to this means, the space can be zoned without using furniture and furniture, so that the design of the space can be easily enhanced.

Furthermore, when scene 1 was played back via the multi-manager using the information terminal, and then other scenes such as scene 3 and scene 4 were played back sequentially using the information terminal, each scene was switched in about a few seconds. It was. Therefore, when zoning is performed by this method, switching of each scene is completed in a few seconds, and as a result, the layout of the office can be changed in a few seconds. For example, on days when the need for concentrated space is high, such as busy days in the office, switching from scene 1 to scene 3 will increase the number of seats in the centralized space in the office from 8 to 14 to meet the needs for concentrated space for workers. As a result, it becomes easier to improve the work performance of workers and organizations. Alternatively, in the case of a fallow day, if the scene 4 is switched, the number of seats in the concentrated space becomes 0 and the co-creation space becomes 14 seats, which has the effect of reducing the stress of the organization and increasing the amount of communication. Furthermore, it is possible to adjust the number of seats in the concentrated space in the afternoon during the lunch break by referring to the utilization rate of the concentrated space in the morning of one day. According to this method, active zoning that changes the layout in a short time in a cycle such as hourly, daily, or monthly, which is difficult with the above-mentioned method using furniture and furniture, is possible.

In the conventional office scene, there is no method of playing different sound contents in different areas of the same room, and there is no space (room) that adopts such a method. On the other hand, since the present application uses such a lighting method and a control method, it is possible to realize a remarkable effect that could not be predicted by the conventional knowledge of lighting, especially in the ABW office scene.

[2. Zoning using illumination light]
Using the multi-manager operation application, the position information of each base light 73 is stored by mapping the 28 base lights 73, and as shown in FIG. 1, 12 base lights 73 and 8 task lights 75 are stored. Is set as a lighting device belonging to the lighting group 1, four base lights 73 are set as lighting devices belonging to the lighting group 2, and 12 base lights 73 and six task lights 75 are set in the lighting group 3. Set as the lighting equipment to which it belongs. Further, as shown in FIG. 2, four scenes were set for each of the lighting groups 1 to 3, and the color temperature and dimming rate values were set for each groove in each scene.

Here, the setting of each scene can be easily executed using an information terminal in which an existing scene setting application is installed, for example, a smartphone, a tablet, a remote controller, or the like. Then, each scene was actually reproduced. Specifically, when the blind curtain of the window of the ABW office 20 was closed and the scene 1 was played back via the multi-manager using the above information terminal that was zoned by the sound content, the appearance of the desk group 1 and the desk Group 2 was split. Subsequently, when other scenes such as scene 3 and scene 4 were sequentially reproduced using the information terminal, each scene was switched in about a few seconds.

In the desk group 1 of the scene 1, the illuminance of the task light 75 was larger than the illuminance of the base light 73, and in the desk group 2 of the scene 1, the illuminance of the task light 75 was smaller than the illuminance of the base light 73. More specifically, the desk group 1 of the scene 1 had a non-uniform illuminance distribution in which the illuminance was high only in the central portion of the work desks D07 to D014 and the illuminance was decreased as the distance from the central portion was increased. In addition, the illuminance of the floor and walls around the work desk was low, and the space had a low sense of brightness. On the other hand, in the desk group 2 of the scene 1, the illuminance of the work desks D01 to D06 has a higher uniform illuminance distribution than that of the desk group 1, and the illuminance of the floor and walls around the work desk is also high, and the feeling of brightness is high. It was a space.

At this time, when the worker is seated in the desk group 1, the illuminance is high only in the central part of the work desks D07 to D014, which the worker should pay more attention to, so that the cognitive noise factor of the peripheral visual field is reduced, so that the worker It is easy to immerse yourself in the work and improve the efficiency of intensive work. Further, in this method, since the dimming rate of the base light 73 is set low, the visibility of the peripheral visual field such as the wall or the floor is lowered, so that the work desks D07 to D014 and the work are more absorbed. It is easy to enhance the effect. Further, by setting the dimming rate of the base light 73 to be low, the worker working in the desk group 1 may not be able to see the facial expression well or may be on the face when other workers see it from the outside. It's hard to talk to because it looks moody because of the shade. That is, the worker working in the desk group 1 is likely to be talked to by another worker and the probability that the work is interrupted is likely to decrease, and as a result, the efficiency of the intensive work is likely to be improved. From the above, when the scene 1 is reproduced, the desk group 1 is a space that easily functions as a centralized space, and can be treated as corresponding to the centralized work space control area in the present disclosure. On the other hand, in scene 1, the desk group 2 is a space that easily functions as a co-creation space because the color temperature is low and it is easy to increase the feeling of relaxation and the amount of communication between a plurality of people. It can be treated as corresponding to the area.

The illuminance distribution in the space is significantly different between the desk group 1 and the desk group 2. In particular, the desk group 1 is characterized in that the illuminance of the floor and walls around the work desk is lower, which causes a high sense of division of the space in appearance between the two desk groups. Further, since the color temperature of the illuminations of the desk group 1 and the desk group 2 are significantly different from each other, the appearance of the space is highly divided.

As for the zoning effect, the larger the difference in the illuminance distribution and the color temperature of each group, the easier it is to enhance the effect. According to this means, the space can be zoned without using furniture and furniture, so it is easy to enhance the design of the space, and when the lighting control such as dimming and toning is digitized, the layout is changed instantly by the lighting control. This is preferable because active zoning is possible. Further, there is a buffer area between the desk group 1 and the desk group 2. This area is not a space intended for workers to work for any purpose, but a space used as a passage in a normal office. The buffer area has an effect of enhancing the zoning effect as compared with the case where the desk group 1 and the desk group 2 are adjacent to each other by making the lighting and the sound different for both the desk group 1 and the desk group 2. The maximum width of the buffer area is not particularly limited, but a range of 0.5 m to 5 m is preferable because the zoning effect can be easily enhanced while maintaining the functional density of the office space.

Further, the desk group 1 and the desk group 2 have different work contents to be urged to the workers. For example, the desk group 1 of this embodiment promotes intensive work, and the desk group 2 promotes relaxation and communication. Therefore, only in appearance. In addition, there is a difference in the functional usage of each space, so this effect also contributes to the zoning effect.

When zoning is performed by this method, even with the method using illumination light, switching of each scene is completed in a few seconds, and as a result, the layout of the office can be changed in a few seconds. For example, on a busy day in the office or on a day when there is a high need for a concentrated space, as described above, switching from scene 1 to scene 3 will increase the number of seats in the centralized space in the office from 8 to 14 for workers. Satisfying the needs of centralized spaces can result in better work performance for workers and organizations. Alternatively, as described above, in the case of a fallow day, if the scene 4 is switched, the number of seats in the concentrated space becomes 0 and the co-creation space becomes 14 seats, which has the effect of reducing the stress of the organization and increasing the amount of communication. There is. Furthermore, it is possible to adjust the number of seats in the concentrated space in the afternoon during the lunch break by referring to the utilization rate of the concentrated space in the morning of one day. According to this method, even with the method using illumination light, active zoning that changes the layout in cycles such as hourly, daily, and monthly, which is difficult with the method using furniture and furniture, is possible. In the conventional office scene, it is common to illuminate areas such as work desks and aisles with high uniformity of color temperature and illuminance distribution. On the other hand, since the present application uses such a lighting method and a control method, it is possible to realize a remarkable effect that could not be predicted by the conventional knowledge of lighting, especially in the ABW office scene.

[3. Synergistic effect of zoning by sound and zoning by illumination light]
In this embodiment, the lighting control and the sound control are linked, and the sound content and the purpose of the lighting that can be predominantly provided to the desk groups 1 and 2 are the same. Specifically, for example, when the scene 1 is reproduced, in the area of the desk group 1, the speaker group 1 outputs the murmuring sound of a stream that easily enhances the efficiency of the concentrated work described above, and further enhances the efficiency of the concentrated work. Easy illumination light is applied. Therefore, in the area of the desk group 1, it is possible to superimpose the effect of easily increasing the efficiency of the concentrated work by sound and the effect of easily increasing the efficiency of the concentrated work by lighting, and the synergistic effect of the superimposition makes it possible to superimpose the effect of easily increasing the efficiency of the concentrated work by lighting. Can be changed to an area where the efficiency of concentrated work can be easily increased.

On the other hand, in the area of the desk group 2, the speaker group 2 outputs sound content that makes it easy for the above-mentioned person to increase the feeling of relaxation and the amount of communication between a plurality of people, and further, it is easy to increase the feeling of relaxation and the amount of communication between a plurality of people. Illumination light is emitted. Therefore, in the area of the desk group 2, it is possible to superimpose the effect of enhancing the relaxing feeling and communication by lighting and the effect of easily enhancing the relaxing feeling and communication by sound, and the synergistic effect of the superimposition makes it possible to superimpose the effect of enhancing the feeling of relaxation and communication. Can be changed to an area where it is easier to feel relaxed and communication is much easier. Therefore, the effect of the intended purpose of each desk group 1 or 2 area can be made remarkable.

When sound control and lighting control are linked, the operations do not have to be strictly synchronized. For example, the start time or end time of sound content switching and the start time or end time of lighting scene switching are Even if there is a slight deviation, the above-mentioned effects are not lost. Further, in the case where such a deviation occurs, the deviation time between the start time or end time of sound content switching and the start time or end time of lighting scene switching may be any time, but within 30 minutes. It is preferably within 10 minutes, more preferably within 1 minute, and most preferably within 10 seconds. When the deviation time is within 30 minutes, the layout change can be achieved sufficiently quickly and with less labor than the layout change involving the transportation and re-installation of general furniture and furniture.

[Overview of the acoustic control system 10 and detailed explanation of each main configuration]
Next, an overall outline of the acoustic control system 10 and a detailed description of each main configuration will be given. More specifically, first, the overall outline of the acoustic control system 10 will be described, and each configuration included in the acoustic control system 10 will be described in detail.

<Overview of Acoustic Control System 10>
FIG. 3 is a block diagram showing a main configuration of the acoustic control system 10. As shown in FIG. 3, the acoustic control system 10 includes a control system 30, a plurality of speaker systems 50, and a lighting system 70. As shown in FIG. 3, in the acoustic control system 10, the control system 30 outputs a wireless control signal to each speaker system 50 and the lighting system 70 to control the operation related to the sound output of each speaker system 50. The operation related to the illumination light emitted by the illumination system 70 is controlled.

Hereinafter, each configuration will be described in detail in the order of the speaker system 50, the lighting system 70, and the control system 30. In the following description, the various control units 31, 53, 76, that is, the various processors include, for example, a CPU (Central Processing Unit). Further, various storage units 32, 52, 78 are composed of a hard disk drive (HDD), a semiconductor memory, etc., and the semiconductor memory is a non-volatile memory such as a ROM (Read Only Memory), a RAM (Random Access Memory), etc. Consists of volatile memory. The various storage units 32, 52, 78 may be applied to any information storage medium such as a flash memory or a solid state drive (SSD). The various storage units 32, 52, 78 may be composed of only one storage medium, or may be composed of a plurality of different storage media. The CPU reads and executes a program or the like stored in advance in various storage units 32, 52, 78. In addition, the non-volatile memory stores a control program, a predetermined threshold value, and the like in advance. In addition, the volatile memory temporarily stores the read program and processing data.

<Speaker system>
The speaker system 50 provides sound to the space under intended control, and includes a speaker element section 51 that outputs sound, a content storage section 52 for storing sound content, and playback of sound content. It includes at least a content control unit 53 for stopping or changing, a speaker radio signal receiving unit 54 for receiving a radio control signal, and a power supply unit 55. The above components may or may not be housed inside one housing. The speaker system 50 can be miniaturized when it is housed inside one housing. Further, when the speaker system is housed inside one housing, the installation conditions of the speaker system 50 can be easily changed in the ABW office 20 where the flexibility of layout change is required, which is preferable. The speaker element section 51 is for producing sound, and is composed of, for example, an element that converts a known electric signal into a physical signal.

At least the sound content data is stored in the content storage unit 52. Further, the sound content data is a digitized version of the pre-recorded sound, and is formed in a format such as a WAV format or an MP3 format.

The content storage unit 52 is, for example, a RAM or a flash memory, and may include data other than sound content as long as the storage capacity allows. The content storage unit 52 may be mounted on a board, or may be detachable by the user's hand like an SD card. The content control unit 53 causes the speaker element unit 51 to output the content based on the content data based on the content data stored in the content storage unit 52 and the software that reproduces the content data stored in the content storage unit 52. The control signal is output, and the speaker element section 51 executes an operation of outputting the content based on the content data. Here, the software may be readable by a general-purpose operating system such as LINUX or Windows, and the software is programmed in an arbitrary language such as C language or Python.

The speaker wireless signal receiving unit 54 receives from the control system 30 a wireless control signal related to the timing at which the content control unit 53 executes a process of controlling any of the volume, the content, and the reproduction time position. The speaker radio signal receiving unit 54 has a transmission function, and a radio signal related to the current information of any one of volume, content, and playback time position, and a radio signal including other information are predetermined. It may be transmitted to one or more information devices.

The power supply unit 55 supplies electric power to the components of the speaker system 50, and may include, for example, a household outlet, a duct rail, a regulated power supply, and the like. When the power supply unit 55 includes a duct rail, it is preferable because the installation conditions of the speaker system 50 can be easily changed in the ABW office 20 where the flexibility of layout change is required. In this case, although not particularly shown, the speaker system 50 is separately provided with a mounting mechanism or the like for fixed mounting on the duct rail.

<Lighting system>
The lighting system 70 provides illumination light to the space under intended control, and includes a plurality of base lights 73, a plurality of task lights 75, a dimming and toning control unit 76, and a radio signal receiving unit for lighting. 77 and storage unit 78 are included. The device form of the task light 75 is not particularly limited, and as the task light 75, a desk light, a down light, etc. can be adopted in addition to the above-mentioned spot light, but the task light 75 is like a spot light. It is preferable that the light distribution is controlled so as to collect the light in a specific area because it is easy to control the illumination range of the work desk. More specifically, the spotlight may have a structure in which a person adjusts the irradiation direction of the spotlight by applying an external force, and the spotlight can be freely rotated by a motor or the like with a remote controller. The structure may be such that the irradiation direction of the light can be automatically adjusted in any of the downward directions. If at least one spotlight can change the emission direction of the illumination light in any direction at the installation position, the degree of freedom of the gap between the work desks in the longitudinal direction in the centralized space can be increased, and the width in the centralized space can be increased. The degree of freedom in the gap between the work desks in the direction can be increased, and the degree of freedom in the layout of the concentrated space can be increased. Further, when at least one spotlight can freely adjust the irradiation direction of the spotlight with a remote controller, the irradiation direction of the spotlight can be safely adjusted from the ground without using a stepladder or the like. Further, as described above, it is preferable to adopt a dimming toning type spotlight as the task light 75.

The task light 75 is a light for improving work efficiency of a worker's work, for example, a personal computer operation work, a writing work, a reading work, etc., and is a light that is selectively illuminated on a visual target area of a work desk. The visual target area is an area that can be generally seen when working on a work desk. For example, when a personal computer (hereinafter, simply referred to as a personal computer) is placed behind the center of the work desk for operation. The central part of the work desk is the center of the visual field area. At this time, changes in the visual object due to physiological factors or accidental changes in posture or line of sight are not taken into consideration. In other words, events such as looking up at the ceiling for temporary thoughts or stretching, shifting your eyes to the wall, shifting your eyes to the floor due to sneezing or coughing, or shifting your eyes because someone talked to you are the work desks. It is not considered as a significant change in the visual target area in D01 to D14.

The illumination range of the task light 75 is preferably limited to a part of the visual target area, and for example, the illumination range is preferably 30% to 90% with respect to the area of the work desk. The illumination range of the task light 75 is not particularly limited, but is preferably substantially circular or substantially polygonal. By doing so, the brightness of the visual target region becomes brighter than the brightness of the region other than the visual target region, and the cognitive noise of the peripheral visual field is reduced. Therefore, the worker's consciousness is directed toward the work desk side, and it is easy to improve work efficiency.

Here, the illumination range can be calculated as a position where the maximum value of the amount of light per unit area reaching the work desk is halved, and is generally a range called a half width. The illumination range can be measured and calculated by using a known illuminometer. The color temperature of the task light 75 is not particularly limited, but it is preferable that the color temperature is 4000K to 6500K because it is easy to enhance cognitive concentration.

The base light 73 is a lighting for increasing the brightness of the room, and is a lighting for uniformly illuminating the room. The light distribution of the base light 73 is preferably wider than that of the task light 75 in order to uniformly illuminate the room. The color temperature of the base light 73 is not particularly limited. The base light 73 is preferably a dimming toning type. The device form of the base light 73 is not particularly limited, and any device such as a ceiling light, a line light, a pendant light, a spotlight, and a light bar can be used.

The illumination wireless signal receiving unit 77 receives a dimming / coloring signal described later from the control system 30. Further, the dimming / coloring control unit 76 includes dimming / coloring information included in the dimming / coloring signal received by the lighting radio signal receiving unit 77 and a lighting device 73 stored in advance in the storage unit 78. The dimming / coloring control of the plurality of base lights 73 and the plurality of task lights 75 is executed with reference to the dimming / coloring control programs of the 75.

<Control system>
The control system 30 is for controlling a plurality of speaker systems 50, for example, for general-purpose information terminals such as personal computers, smartphones, tablets, and multi-device interlocking control such as multi-managers (Panasonic: NQ51101). Includes a dedicated dedicated control terminal and at least one of them.

Dedicated control terminals are user interfaces that human users can pick up and use, such as personal computers, smartphones, and tablet terminals, that is, display devices such as displays, input devices such as keyboards and touch panels, and are lightweight and lightweight. It is not necessary to have a housing shape that is easy to hold, and for example, the housing shape may be such that it can be easily embedded in a hole of Φ100 mm formed in the ceiling surface and fixedly attached. In this case, it is preferable because it is easy to enhance the design of the space and crosstalk of wireless communication is unlikely to occur. Alternatively, the housing shape may be such that it can be attached to a duct rail provided on the ceiling surface. In this case, it is preferable because the design of the space can be easily enhanced and crosstalk of wireless communication is unlikely to occur, and the user can easily change the position condition of the dedicated control terminal.

The control system 30 includes a control unit 31, a control condition storage unit 32 in which software including control conditions (information) is pre-installed, and a control system radio signal transmission unit 33. Various control programs and data used for control are pre-installed in the control condition storage unit 32. The control condition storage unit 32 stores data related to the control conditions of the speaker system 50 and stores data related to the control conditions of the lighting system 70.

The data related to the control conditions of the speaker system 50 include, for example, the volume when the sound content is reproduced from the speaker system 50, the type of the sound content, the reproduction position of the sound content, the group information of the plurality of speaker systems 50, and the plurality of speakers. The control scene information of the system 50, the schedule information for determining the timing of the control, and the like. The control condition storage unit 32 may include data other than the data related to the control conditions of the speaker system 50 as long as the storage capacity allows. The control condition storage unit 32 mainly stores data related to the control conditions of the speaker system.

Here, the playback position of the sound content indicates, for example, when there is a set of sound content in 5 minutes, which part of the 5 minutes is currently being played, that is, expressed in time. It can be done. For example, when the above-exemplified sound content is played from the beginning and 1 minute has passed, the playback position of the above-mentioned sound content is 1 minute, and the speed is further reversed by 10 seconds, and when another 20 seconds have passed, the above The playback position of the sound content is 1 minute and 10 seconds (excluding the fast rewind operation time).

Further, the group information of the plurality of speaker systems 50 is management information for collectively storing the group information of the plurality of speaker systems 50 in the storage unit as described above. For example, in the example shown in FIG. There are four speaker systems 50a to 50d. For example, the speaker system 50a and the speaker system 0b are the speaker group 1 (speaker group 1), the speaker system 50c and the speaker system 50d are the speaker group 2 (speaker group 2), and the like. This is information on the concept of combining a plurality of speaker systems 50a to 50d.

In this case, as described above, for example, when different sound contents are provided to two predetermined areas 1 and 2 of the ABW office 20 and active zoning is performed, the area 1, the speaker group 1, and the area 2 are used. It is preferable to support the speaker group 2 because it is easy for the user to set, manage, and operate a plurality of speaker systems, which are originally complicated.

Group information of a plurality of speaker systems is managed by software or an application, for example. Grouping may be set and saved by operating a tablet terminal, for example. For a plurality of grouped speaker systems 50, the same control is performed at the same time, for example, the volume is set to zero at 10:00, the sound content is switched to b.wav at 17:00, and the like. Can be operated to do.

Regarding the control of the plurality of grouped speaker systems 50, signal delay is allowed, and variation in device operation is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of the grouped devices. When the operation variation of the speaker system 50 is within the above time, it is preferable because the layout change can be easily achieved quickly and labor-savingly as compared with the layout change involving the transportation and re-installation of general furniture and furniture.

The group setting may be included as a function of software or an application that operates the control system 30, but it is not always defined by the name of "group", and for the purpose of achieving the above-mentioned purpose, it is not always defined. For example, any expression method such as "area" and "zone" may be selected.

Software and applications that operate the control system 30 may be included in the control system 30. In this case, software or an application may be written in a part of the capacity of the control condition storage unit 32. Further, although not particularly illustrated, the control system 30 includes a CPU including an operation system for operating the software and applications, and a user interface such as a display and an input device that facilitates operation of control information for the user. It may be included as appropriate. Here, such a user interface may be configured by, for example, a terminal such as a personal computer, a smartphone, or a tablet.

Alternatively, the software or application that operates the control system 30 may not be included in the control system 30. In this case, the content of the control condition storage unit 32 is changed by using the control condition setting unit 90 provided separately from the control system 30. The control condition storage unit 32 can be composed of, for example, a terminal having a control unit and an information storage medium in which software is installed. In the case of the example shown in FIG. 3, the control system 30 can be configured by, for example, the above-mentioned multi-manager having a storage unit in which software or the like is installed, and the control condition setting unit 90 is a setting tablet in which the software or the like is installed. It can be composed of Panasonic: NQ51181).

Further, although not particularly shown, a control system for controlling the lighting system may be provided in addition to the control system 30 for controlling the speaker system. Further, in addition to the control system radio signal transmission unit 33 for transmitting the radio signal to the speaker system, a control system radio signal transmission unit for transmitting the radio signal to the lighting system may be provided separately.

As described above, the control scene information of the plurality of speaker systems is the management information for collectively storing the control parameters related to the plurality of speaker systems in the storage unit. For example, as described above, the control scene information includes the conditions of the sound content reproduced by the above-mentioned four speaker systems 50a to 50d, the speaker system 50a: a.wav, the speaker system 50b: a.wav, and the speaker system 50c :. This is information on the concept of summarizing b.wav and the speaker system 50d: b.wav as scene 1.

Considering that active zoning is performed in the ABW office 20, since 4 or more or 10 or more speaker systems are used, the user can set control parameters such as the volume and sound content type of each unit for playback. It is very complicated to do, but it can be greatly improved by managing it collectively as a scene. In addition, other matters relating to the requirements of the scene are as described in relation to the group information of the plurality of speaker systems 50.

The control system wireless signal transmission unit 33 wirelessly transmits a signal related to the control conditions to the speaker system 50. The control system wireless signal transmission unit 33 has a reception function, and may wirelessly receive signals related to the control state from the speaker systems 50a to 50d, and may receive wireless signals from other information devices. May be good. As the radio control signal, radio communication of a known and arbitrary frequency is preferably used, and for example, a radio signal conforming to Wi-Fi, Bluetooth standard, or the like may be used, or 920 MHz or the like may be used.

The control unit 31 of the control system 30 is at least one of the volume, type, and playback position of the sound content output by the plurality of speaker systems 50 based on various software and various data stored in the control condition storage unit 32. Is executed at the same time as the control system radio signal transmission unit 33 to transmit the radio control signal.

When the purpose of this is to perform active zoning in the ABW office 20 using a plurality of speaker systems 50, for example, the conditions of the sound content reproduced by the above-mentioned four speaker systems 50a to 50d, the speaker system 50a: a. From wav, speaker system 50b: a.wav, speaker system 50c: b.wav, speaker system 50d: b.wav (condition 1), speaker system 50a: b.wav, speaker system 50b: b.wav, speaker system 50c : B.wav, speaker system 50d: By changing to b.wav (condition 2) and making "b.wav" sound content that makes it easier for workers to concentrate, it is a space for intensive work in ABW office 20. Effective spatial control that can instantaneously increase the control area can be achieved, but in this example, two speaker systems, namely the speaker system 50a and the speaker system 50b, a. It is controlled to change from wav to b.wav.

Further, at this time, for example, the data of the above-mentioned condition 1 and the condition 2 are stored in advance in the control condition storage unit 32, and further, "the control condition is changed from the condition 1 to the condition 2 at 9:00". By storing and enabling the schedule, the playback content is switched to b.wav from the control system radio signal transmitter 33 to the speaker system 50a and the speaker system 50b at 9:00. A radio control signal is transmitted at the time. By doing so, the user's intention and desire to "increase the space for intensive work in the ABW office at 9:00" are achieved. Therefore, in the embodiment of the present invention, the speaker system is not controlled in order to change the effect of the space as has been conventionally performed, but a flexible layout change that can be effectively utilized especially in an ABW office or the like, that is, active. For zoning, it is necessary to perform wireless control at the same time to control a plurality of speaker systems.

Here, the same period does not mean that there is no time difference of any minute, signal delay is allowed, and variation in the operation of the speaker system is also allowed. For example, the permissible variation in speaker system operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and signals within this range. Alternatively, the instruction delay is included in the behavior of the grouped speaker systems. When the operation variation of the speaker system is within the above time, it is sufficiently small compared to the layout change that involves the transportation and re-installation of general furniture and furniture, and it is universally possible to achieve the layout change with labor saving. This is because it is meaningful.

In addition to the above-mentioned control, any sound content related to the layout of the user's ABW office 20 can be used, such as reducing the space for intensive work and increasing the space for relaxing by using sound content that can encourage workers to relax. The control method can be derived according to the request, and it is obvious that the means of providing the present application is universally effective in any of the cases and is included in the intention of the present application.

Also, all the processing performed by the control system on the speaker system does not have to be compatible with multiple speaker systems, and sometimes a wireless control signal is transmitted to a single speaker system as needed. Such processing may be included.

Next, the control of the lighting system 70 in the control system 30 will be described. The control unit 31 causes the control system radio signal transmission unit 33 to output a dimming toning signal, which is a radio signal, with reference to software and data related to the illumination light stored in the control condition storage unit 32. The signal format of the dimming toning signal is not particularly limited, and any known dimming signal, Wi-Fi, Bluetooth, etc. can be used.

The control condition storage unit 32 stores group information of a plurality of lighting devices 73 and 75. Grouping may be set and saved by operating the control condition setting unit 90. The same command is sent to the plurality of grouped lighting devices 73 and 75 all at once, and for example, the same dimming and toning control is applied. Regarding the dimming and toning control of the plurality of grouped lighting devices 73,75, that is, the group control, signal delay is allowed, and variation in the operation of the devices is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of the plurality of luminaires 73,75 grouped together. When the operation variation of the equipment is within the above time, it is preferable because the layout change can be easily achieved quickly and labor-savingly as compared with the layout change involving the transportation and re-installation of general furniture and furniture. The group setting may be included as a function of the application that operates the control device, but it is not always defined by the name of "group". It is preferable to set a group in the application for operating the control device or the storage unit included in the control device because it is easy for the user to manage and change the lighting and its control parameters.

It is a very complicated task for the user to set and reproduce control parameters such as dimming rate and toning rate of each of the plurality of lighting devices 73 and 75. This is because, in a general ABW office 20, 10 or more or 30 or more lighting devices are used, and in many cases, 100 or more are used. Therefore, there is known a method of collectively storing and managing control parameters of a plurality of lighting devices 73 and 75 in a storage unit, and this is referred to as a scene in the present application. By doing so, not only is it easy for the user to manage the conditions of the control parameters for the plurality of lighting devices 73 and 75, but also those conditions can be instantly reflected in the plurality of lighting devices at a desired timing. (Hereinafter referred to as regeneration) is also easy, which is preferable. Further, the user can instantly switch between two or more intended setting conditions by storing a plurality of types of scenes in the control condition storage unit 32 in advance. The settings of each scene may be set in any way depending on the usage needs. For example, unlike the example shown in FIG. 2, the dimming rate of 10 base lights in scene 1 is set to 100%. It may be stored in the storage unit, and further, the dimming rate of the above-mentioned 10 base lights may be set to 30% in the scene 2 and stored in the storage unit. Then, when the scene 1 is played back, the dimming rate of the 10 base lights is instantly set to 100%, and when the scene 2 is played back from this state, the 10 base lights are instantly set. The dimming rate of the above may be set to 30%. In this way, it is preferable that the dimming control of a large number of lighting devices can be realized in a much shorter time and with less labor than the work of resetting the dimming rate of 10 lighting devices each time. The scene setting may be included as a function of the application that operates the control device, but it is not always defined by the name of "scene". Further, as the setting of each scene, the scenes of groups 1 and 2 may be set as follows. For example, in scene 1, group 1: dimming rate 0% and group 2: dimming rate 50% may be set, and in scene 2, group 1: dimming rate 50%, group 2: dimming rate 0. May be set to%. By setting the scene in this way, it is possible to instantly exchange a zone where workers can easily concentrate and a zone where workers can easily relax and communicate with other workers, and when the scales of the two zones are different. In addition, the scale of each zone can be changed instantly according to needs. Regarding dimming and toning control of a plurality of devices in a scene, that is, group control, signal delay is allowed, and variation in device operation is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of multiple devices that are scened. In this way, by controlling multiple lighting systems at the same time as well as performing wireless control at the same time to control multiple speaker systems, flexible layout changes that can be effectively used especially in ABW offices, etc. That is, it is possible to further enhance the effect of active zoning.

(One test of sound interruption / sound deviation and its evaluation, etc.)
<Outline of sound interruption / sound deviation test and one test result>
In comparison with the acoustic control system 10 of the present disclosure, the present inventor continuously follows the BlueTooth standard from the control system while the speaker system does not have a content storage unit and each speaker system is playing sound. We created a comparative acoustic control system that differs only in that it receives sound content data by radio signal. Then, in both the acoustic control system 10 of the present disclosure and the acoustic control system of the comparative example, scenes 1 to 4 shown in FIG. 2 are switched every 20 seconds to determine whether or not sound interruption / sound deviation occurs. The test was conducted.

FIG. 4 is a table showing the results. As shown in FIG. 4, in the acoustic control system of the comparative example, sound interruption / sound deviation frequently occurred, whereas in the acoustic control system 10 of the present disclosure, sound interruption / sound deviation did not occur.

<Evaluation of the above test result>
From one test result, when the acoustic control system 10 of the present disclosure is used, when active zoning is realized in an ABW office using four or more or ten or more speaker systems, excellent acoustic control with almost no sound interruption or sound deviation occurs. I was able to confirm that the system could be realized.

<Consideration based on the above one test result>
With the diversification of office work styles and the shift to ABW, the design and flexibility (easiness of change) of the spatial layout are preferred, and we are trying to realize an acoustic control system with a wireless system that is highly designable and easy to change. In this case, in the conventionally known form of wirelessly communicating sound content data with Bluetooth or the like, it is possible to use a general-purpose and inexpensive wireless speaker that has been widely released in recent years, and there is an advantage that it can be easily realized. There is. However, when attempting active zoning using multiple, for example, four or more speaker systems, the sound is cut off due to mixing with Wi-Fi radio waves of business computers and OA equipment existing in the office and blocking of the human body. Becomes noticeable. According to the technique of the present disclosure, the above-mentioned easy feasibility is impaired by intentionally storing a large amount of sound content data in a speaker system located at the end (edge) of the processing system of the entire system. It is possible to obtain a special and remarkable effect that can avoid system defects that are practically fatal to the user, such as sound interruption and sound deviation, which far surpasses.

(Structure and effect of the acoustic control system of the present disclosure)
The control in the acoustic control system 10 and the specific aspects of each configuration have been described above. In this item, the essential configuration of the acoustic control system 10 and its action and effect, and the configuration preferable to be adopted and its action and effect will be described, which have been clarified from the above description.

<Indispensable configuration and the action and effect derived from that configuration>
The acoustic control system 10 includes two or more speaker systems 50a to 50d that provide sound to the space, a control system 30 that transmits a control signal to each speaker system 50a to 50d, and the like.
To be equipped. Further, each of the speaker systems 50a to 50d includes a speaker element unit 51 for outputting sound, a content storage unit 52 for storing sound content data, and a content control unit 53 for executing one or more operations related to sound content. And a speaker radio signal receiving unit 54 for receiving a radio control signal, and a power supply unit 55. Further, the control system 30 includes a control condition storage unit 32 for storing information regarding control conditions of the speaker systems 50a to 50d, and a control system radio signal transmission unit 33 for transmitting a radio control signal. Further, the content control unit 53 reads out the sound content data stored in the content storage unit 52 based on the wireless control signal received by the speaker radio signal receiving unit 54, and the speaker element unit 51 reads the sound based on the sound content data. Perform one or more controls, including sound output control to output. Further, one or more of the control system 30 including the same time control for causing the control system radio signal transmission unit 33 to output the radio control signal so that the operations related to the sound contents are executed at the same time with respect to the plurality of speaker systems 50a to 50d. To control.

According to this configuration, the content storage unit 52 for storing the sound content data is provided in the speaker systems 50a to 50d located at the end (edge) of the processing system of the entire system, so that the sound content data itself can be controlled by the control system. It is not necessary to continuously transmit from 30 to the speaker systems 50a to 50d, and the control system 30 only transmits radio control signals having a very small capacity and defining the operation of the speaker systems 50a to 50d. You can send it to. Therefore, it is possible to avoid systematic defects such as sound interruption and sound deviation, which are fatal to the user.

Further, one or more of the control system 30 including the same time control that outputs a radio control signal from the control system radio signal transmission unit 33 so that the operations related to the sound contents are executed at the same time with respect to the plurality of speaker systems 50a to 50d. Since the control of the above is performed, the zoning can be changed by the contents output by the plurality of speaker systems 50a to 50d in a short time, and the active zoning can be realized.

<Multiple configurations that are preferable to select and the effects derived from each configuration>
Also, one or more actions related to sound content can be one or more of playing sound content, stopping sound content, changing sound content, changing the volume of sounds that make up sound content, and changing the playback position of sound content. It may contain 2 or more, 3 or more, 4 or more, and preferably all of them.

According to this configuration, the operation corresponding to the user's needs can be executed flexibly and in a short time. The one or more operations related to the sound content may be any operation related to the sound content, for example, an operation of adjusting the sound output direction of the speaker system when the speaker system can change the orientation of the housing by the motor. Good.

Further, the control condition storage unit 32 may include one or more group information relating each speaker system 50a to 50d to one or more groups.

According to this configuration, zoning related to sound content can be functionally executed, and further, the division effect due to zoning can be made remarkable.

Further, one or more scene information is stored in the control condition storage unit 32, and the scene information may include sound information output by the speaker systems 50a to 50d.

According to this configuration, the control can be simplified to each stage, and the desired zoning can be sequentially realized.

Further, the acoustic control system 10 may include a lighting system 70 including a plurality of task lights 75 for illuminating the work surface of the space and a plurality of base lights 73 for illuminating a wider area than the work surface. Good. Further, the control system 30 has a centralized work space control area (desk group 1 in scene 1) and a base light in which the illuminance of the task light 75 is larger than the illuminance of the base light 73 via the radio signal transmission unit 33 for the control system. Dimming and toning the plurality of task lights 75 and the plurality of base lights 73 so as to generate a decentralized work space control area (desk group 2 in scene 1) in which the illuminance of the task light 75 is smaller than the illuminance of the 73. Illuminance light zoning control to be controlled may be performed.

According to this configuration, the space division effect (division effect) due to zoning can be made exceptionally remarkable by the synergistic effect of zoning due to the output of sound content and zoning due to illumination light.

The present disclosure is not limited to the above-described embodiment and its modifications, and various improvements and changes can be made within the scope of the claims of the present application and the equivalent scope thereof.
