Description

[Detailed description of the invention] (Field of industrial application) This invention is designed to adjust acoustics by changing the reverberation according to the user's requests and preferences in a relatively small area, such as an audio room in a private residence. However, it is extremely easy to obtain without requiring complicated mechanical equipment or structure, and the convenience is increased by allowing necessary records, cassettes, etc. to be accommodated without impairing the room functions.

(Prior Art) As is known, variable reverberation devices are used in large and small hall facilities used for various plays, musical performances, etc. in order to obtain optimal acoustic effects. This device changes the reverberation time by changing the room volume, the room surface area, or the average sound absorption coefficient of the room. For example, one half of the cylindrical rotating body is used as a reflecting surface and the other half as a sound absorbing surface. , a rotary reverberation variable device that rotates this to expose its reflective or sound-absorbing surface into the room; a reflective plate and a sound-absorbing plate are overlapped and the reflective plate is movable; A reverberation variable device that opens and closes to expose a board, a hanging type variable reverberation device that has a suspended body with a reflective surface and a sound absorbing surface formed on the front and back that can be moved up and down, or a sound absorbing material in the form of a blind on the front of a wall with a reflective surface. There are various types of devices, such as a blind type that allows for free winding and unwinding.

(Problems that the invention attempts to solve) All of the conventional technologies were developed for halls with a considerable number of seats, and all required large-scale mechanical equipment and structures, and were specially designed from the beginning of construction. A proper design and implementation must be carried out. On the other hand, there are signs that it is becoming popular for individuals to use a room in their home as an audio room.
It is completely difficult to apply conventional techniques to such private rooms in residential buildings, and it is customary to make the walls of the private rooms soundproof and to use curtains as a reverberation variable means. In the curtain method, the effectiveness varies depending on the material, structure, number of folds, and even the thickness of the air layer on the back side, and not only is it difficult to obtain precise and advanced reverberation adjustment, but it is also difficult to obtain a precise and advanced reverberation adjustment. In a room, the types of acoustics, content, and sound quality preferences that individuals prefer vary widely, and it is natural that the sound absorption and reflection conditions for reverberation adjustment will also differ. Even if a hall-sized reverberation variable device is miniaturized as it is, it is difficult to apply it to each individual and satisfy them.

(Means for Solving the Problems) The present invention solves the above problems, and allows acoustic adjustment in the limited room of an individual audio room to be performed with precision and advanced content according to the needs of each individual. It is designed to be extremely easy to implement, and specifically, the interior surface of a private room surrounded by walls, walls, ceilings, and floors equipped with a sound insulating structure is Various sound absorption panels and diffusion panels are standardized and have a mounting structure that can be attached and detached in contact with the interior surface.
In order to obtain reverberation changes according to the purpose and use, the panels are laid out in an arbitrary arrangement and combination in a continuous manner. The panel is also used as an opening/closing door for the article storage room.

(Function) According to the technical means of the present invention (see FIGS. 1 and 2), by surrounding the room 1 with a wall 2 having a sound insulation structure, or a ceiling 3 and a floor 4 following the wall 2, , the chamber 1 has a structure that can isolate internal and external sounds, and the interior surface of the chamber 1 is equipped with a low-frequency sound absorption panel B, a medium- and high-frequency sound absorption panel B, which is standardized based on a predetermined shape such as a rectangle or square and a predetermined size. The sound-absorbing panel C and the diffusion panel A have a removable mounting structure,
In order to obtain reverberation changes according to the user's purpose and use, these can be laid out in any arrangement and combination in a continuous manner, so that each user's personal needs can be met. The panel unit type reverberation adjuster 10 that can satisfy the above requirements can be assembled very easily. Moreover, even after installation of these sound absorption panels B, C and diffusion panel A, individual users have the freedom to partially change their placement and reposition them, allowing for more precise acoustic adjustment and higher performance. Personal modifications are easily possible, and each panel A,
Since B and C have a structure in which they are laid in a continuous manner, positioning can be easily performed when changing the pasting. Furthermore, in this invention, these panels A, B,
Sound absorbing panel B at that specific position in group C,
At the attachment position of C or diffusion panel A, an article storage chamber 22 is formed in advance within the interior surface, and the sound absorbing panels B, C or diffusion panel A at the specific position are attached to the front surface of the article storage chamber 22. Records, cassettes, and other audio parts can be safely and securely stored in the article storage chamber 22 without impairing the acoustic adjustment function by installing the door so that it can be used as an opening/closing door that can be covered to open and close freely. This makes it possible to significantly increase the convenience of use for the user without wasting space on the surface of the panel unit type reverberation adjustment body 10.

(Example) An example of the device of the present invention will be sequentially explained with reference to FIG. 1 and the following figures. In the one shown in Figures 1 and 2,
Although the device of the present invention is shown only on the interior surface of the wall 2 surrounding the room 1, the device of the present invention is applied not only to the wall 2 but also to the interior surfaces of the ceiling 3 and floor 4 that follow the wall 2. Of course, it is also possible to implement. Room 1
As illustrated in FIG. 3, the wall 2 that is separated from the outside world is a wall equipped with a known sound insulation structure, such as a glass wool 7 and a space layer 8 interposed between an outer wall material 5 and an inner wall material 6. 9 has an acoustic blocking function by being
This is the booth assembly material that will be connected and assembled. It is common for the room 1 to have openings such as entrances and exits, windows, etc. Although these openings are not shown, for example, a single or double soundproof sash with a sealing structure can be installed on the window so that it can be opened and closed. In addition, a soundproof door with a seal structure is provided at the entrance and exit so that it can be opened and closed freely, and if necessary, a curtain can also be used or a curtain can be used instead. In short, the four walls 2 surrounding the room 1, including the openings, have a sound insulating structure that prevents sound from entering and exiting the room.

A panel unit type reverberation adjusting body 10 according to the present invention is mounted on the interior surface of the room 1, in this embodiment, the inner surface of the wall 2, that is, the surface of the inner wall material 6 facing the room, and can be assembled freely and with the following structure. It will be pasted under any arrangement combination.

The reverberation adjustment body 10 is composed of a diffusion panel A, a low frequency sound absorption panel B, a middle and high frequency sound absorption panel C, and a dimension adjustment panel D used as necessary, as shown in FIG. 2 as an example of the arrangement thereof. be done. In each group of panels A, B, C, and D, the diffusion panel A and the sound absorption panels B and C are, in principle, all of the same length in the vertical direction and the length in the horizontal direction. By using panels of the same shape, such as rectangles or squares, it is possible to standardize the dimensions.On the other hand, with the dimension adjustment panel D, the size of the room 1 and the corresponding size of the wall 2 can be adjusted for each size. Panel A of the same size, which has been standardized, is often different depending on individual residences.
When affixing panels B and C to the interior surface of wall 2 in a continuous manner vertically, horizontally, etc., it is difficult to cover the entire interior surface with panels A, B, and C without excess or deficiency. In response to this, the panel is intended to fill in the unpasted surface, and can be easily cut into various sizes and shapes, and the material is, for example, a panel made of cross-bonded plywood, plywood without cloth, etc. .

As is known, the diffusion panel A is for uniformly reflecting and diffusing sound, and has a reflective surface 11 made of a hard material formed on its surface.
The reflecting surface 11 is an uneven surface extending in the vertical direction, and as shown in FIG. 7, the entire uneven reflecting surface 11 is a convex type reflecting surface 11a having a semicircular convex shape. There are both the diffuser panel _A1 and the diffuser panel _A2 , which has a flat type reflective surface 11b in which the entire uneven reflective surface 11 is a flat surface, but it is up to you which one to use. In the mid-high sound absorption panel C, as is known, as shown in FIG. Glass wool 15 and air layer 16 are placed on the back side of the
At this time, the hole diameter and hole length of the hole 14a in the perforated plate 14 are adjusted depending on the bass range, middle and high range, and the air layer 16 on the glass wool 15 side.
In addition, other materials such as wire mesh, glass wool board, punched metal, cheesecloth, and curtains can also be used.

When attaching the inner wall material 6 of each panel A, B, and C described above to the interior surface, it is suitable for assembly and adjustment to have a detachable attachment structure as necessary. Although various methods can be used, as an example, the third,
The mounting structure shown in FIGS. 4 and 5 can be cited as an example. That is, on the back side of each panel A, B, and C, there is a mounting part 12 made of, for example, a magnet, a hook-and-loop fastener known as the trademark Magic Tape, etc., for removably mounting the panels in contact with the interior surface of the inner wall material 6. At this time, as illustrated in FIG. 3, a peripheral frame 13 is attached to the back of the panel,
The mounting portion 12 may be provided on the peripheral frame 13. Correspondingly, on the inner wall material 6 side of the wall 2,
For example, as mentioned above, if the mounting part 12 is a magnet, use a steel plate, or if it is a hook-and-loop fastener, the mounting part 17 can be attached to and detached from the mounting part 12, or can be engaged with and disengaged from it, such as a hook-and-loop fastener. It is arranged. At this time, the inner wall material 6 is not a single piece that covers the entire wall surface, but is often divided into pieces, so in order to prevent sound from escaping through the gap between the inner wall materials 6, 6, a 5. When providing the mounting part 17 at the joint position as shown in the figure, a sealing material 18 made of a lead plate or the like is stretched, and the mounting part 17
Consideration needs to be given, such as establishing a Reference numerals 19 and 20 indicate respective fixing tools for the mounting portions 12 and 17. Of course, the illustration is only one design example, and other appropriate attachment/detachment structures can be used.

Furthermore, in the present invention, the above-mentioned panel unit type reverberation adjustment body 10 is provided with an article storage structure as illustrated in FIGS. 8 to 12. That is, what is shown in FIG. 8 is the case when installing the diffusion panel _A1 on the wall near the audio equipment 21 (for example, in the case of a listening room, installing the diffusion panel A on the wall near the speaker will prevent the speaker from moving away from the speaker). (Effective for dispersing sound in a well-balanced manner in the room and obtaining stable sound pressure), at least _one panel A, B, C, and an integer number of panels A, B, and C are installed on the interior surface where panel A1 is attached. A diffusion panel A ₁ that occupies twice the area, has an article storage chamber 22 installed in advance, and is shaped and sized to cover the entire opening of the storage chamber 22 is attached to a pivot bracket such as a hinge as shown in FIG. 23 is used to double as an opening/closing door. At this time, the pivot bracket 23 is the peripheral frame 13 mentioned earlier.
Attach using etc. In the example shown in FIG. 8, several shelves 22a are divided into several shelves 22a in the article storage room 22 to store records 24, but of course, the stored items can be freely stored such as records, cassettes, materials, magazines, etc. . A semi-cylindrical diffusion panel as shown in the illustration
When using A ₁ , it is advantageous in that the location of the goods storage chamber 22 is clearly defined, and in this example, the size of the storage chamber 22 is larger than one panel, so it is necessary to use a door that can be opened and closed. The diffusion panel _A1 is also enlarged, and the size of the storage chamber 22 is free. What is illustrated in FIGS. 9 and 10 is a modification of the internal structure of the article storage chamber 22, and as shown in FIG.
When storing the record 24 inside the top wall 2
2b, bottom wall 22c, both side walls 22e and back wall 22
In the box-shaped storage chamber 22 with a front opening consisting of f,
A bendable and extensible rack arm 25 may be provided using the both side walls 22e, and the record 24 may be tilted forward by the arm 25 to facilitate selection, removal, and loading. Furthermore, the examples shown in FIGS. 11 and 12 show the case where the cassettes 26 are stored in the storage chamber 22 which is divided into two levels by the shelf board 22a, but the internal structure of the storage chamber 22 is as shown in the example. Therefore, it can be freely designed according to the purpose and use.

According to the embodiment, when a relatively small-scale room 1 in a private residence is configured as an audio room, rehearsal room, etc., it is extremely easy to make optimal acoustic adjustments according to the user's requests, wishes, and preferences. can get. That is, depending on the size of the room 1 and the arrangement of audio equipment, sound absorbing panels B, C and diffusion panels A are mounted on the interior surface of the wall 2 of the room 1 using removable mounting parts 12 and 17, and the purpose and application are adjusted. They can be combined and pasted in an appropriate arrangement depending on the situation, and the installation can be easily performed by the user himself. Since furniture and fittings other than audio equipment are kept to a minimum in this room, the space for storage and management of stored records and owned cassettes is extremely limited. By attaching a panel that covers the front and doubles as an opening/closing door, space for organizing and storing records, cassettes, and other audio components can be effectively obtained, and the convenience of reliable storage and handling is greatly increased.

(Effects of the invention) According to the invention, diffusion panels and various sound absorbing panels of a constant standard size are placed in contact with the interior surface of a room, or across the walls, ceiling, and floor. In addition to being removably attached, each panel is installed in a continuous manner with each other, and a storage chamber is provided within the interior surface of the panel, and one of the panels doubles as an opening/closing door that covers the front surface of the storage chamber. By combining the uniform reflection and diffusion function of the panel with the sound absorption function of various sound absorption panels ranging from low to high frequency ranges, users can create the optimal desired acoustic space by themselves, and it is also extremely easy to obtain. It has great features, and its removable mounting structure allows it to be easily installed even after installation.
It can be freely changed and adjusted, and since each panel is constructed in a continuous manner,
When changing the position of the panel, alignment can be easily performed and the surface space of the interior surface can be used effectively without wasting space. Furthermore, without compromising the sound adjustment function, various audio parts such as records and cassettes can be sorted and stored in the storage compartment that utilizes the space on the back side of the panel, and can be freely accessed and removed. As a panel unit type reverberation adjustment device, the surface space is not taken up, and the convenience of handling can be significantly increased.Moreover, this device does not require any special functional equipment or power means, and can be installed in a private room of an existing house. It can be easily implemented even for private rooms, and can be implemented at a relatively low cost except for the panel cost, making it an excellent sound adjustment device for private rooms.
