Description

The present invention relates to a wall structure and a compartmentalized structure.

A partition is installed in the room to form a meeting space used for meetings and business negotiations. When discussing trade secrets, personal information, etc., it is desirable that the content of the conversation does not leak outside the meeting space. Therefore, a technique has been put into practical use in which a speaker is provided on the partition panel and a masking sound is emitted so that the conversation content in the meeting space cannot be heard outside (see JP-A-2012-82582). ..

However, when the masking sound is used, there arises a problem that the ambient noise becomes large. That is, when a plurality of negotiation spaces are provided adjacent to each other, there is a masking sound for making the conversation in the adjacent meeting space inaudible, so that it may be necessary to have a relatively loud conversation in the meeting space.

Japanese Unexamined Patent Publication No. 2012-82582

In view of the above inconvenience, it is an object of the present invention to provide a wall structure and a partitioning structure capable of making it difficult for the conversation content to be transmitted to the outside without increasing the ambient noise.

The invention made to solve the above-mentioned problems is a wall structure for dividing an indoor space, and is characterized by having one or a plurality of sound collecting shapes that reflect and converge sound waves incident on the front surface from the front. It is a wall structure.

The sound collecting shape may be a quadratic curve rotating surface, a part of the quadratic curve rotating surface, or a combination thereof.

The quadratic curve rotating surface may be a rotating paraboloid.

The quadratic curve surface of revolution may be a spheroidal surface.

Further, another invention made to solve the above-mentioned problem is a division structure in which a room is divided into one or a plurality of spaces, and the wall structure for dividing the room and the space are placed inside the space. It is a partitioned structure with a table.

It is preferable that the table has a guiding structure for guiding the seating position.

The term "wall" is not limited to an upright wall, but is a concept that broadly includes objects having a surface that divides a space, such as a ceiling and a floor. "Shape that converges three-dimensionally" means that the reflected wave at two or more points on the surface reaches the same point with respect to the sound wave incident from the same point, and the trajectory of the reflected wave at these two or more points. Means a shape drawn in a plane of two or more. Further, the "quadratic curve rotating surface", "rotating paraboloid" and "rotating elliptical surface" may be surfaces approximated by a plurality of planes or spherical surfaces. Further, "a part of the surface of revolution of the quadratic curve" means that it does not exist over the entire circumference around the central axis. Further, the "seating position" is not limited to the position where the speaker sits, but includes the position where the speaker stands when standing and talking.

The wall structure and the partitioning structure of the present invention have a sound collecting shape in which the wall structure reflects and converges sound waves incident from the front, so that even if the wall structure talks in a relatively quiet voice in front of the wall structure, they can talk to each other. Can be heard relatively easily. For this reason, the voice of the speaker is naturally reduced, and it is prevented that the voice leaks to the outside and the conversation content is heard by a third party.

[First Embodiment]
The compartmentalized structure according to the first embodiment of the present invention shown in FIGS. 1 and 2 is formed by a housing unit set including a partition 1 and a table 2. The section structure forms a meeting space by arranging it on the floor surface as shown in the figure. Specifically, the space near the table 2 is separated from the surrounding space by the partition 1, so that the meeting space is defined in the room.

The meeting space formed by the compartmentalized structure of the present embodiment is particularly preferably used for two speakers P to have a one-to-one conversation across a table 2, as shown in FIG. 1, but more. It can also be used for conversations by speaker P and for using a teleconferencing system.

This sound collecting shape is preferably a sound collecting shape that reflects sound waves incident from the front and converges them three-dimensionally.

As described above, the partition structure has the housing material 3 provided with the wall structure, so that the speaker P who talks in the meeting space can easily hear the voice of the other party, and the voice naturally becomes smaller. Therefore, it is possible to prevent the voice of the speaker P from leaking to the outside of the meeting space and being heard by a third party without increasing the environmental noise around the meeting space.

As the three-dimensional sound collecting shape of the wall structure, a quadratic curved surface of revolution, a part of the quadratic curved surface of revolution, or a combination thereof is preferably used. This quadratic curve surface of revolution may be approximated by arranging a plurality of planes side by side. When the three-dimensional sound collecting shape of the wall structure includes a plurality of quadratic curve rotating surfaces, it is preferable that the plurality of quadratic curve rotating surfaces are coaxial. The rotation axis of the quadratic curve rotation surface adopted for the three-dimensional sound collecting shape of the wall structure is preferably a horizontal axis passing through the head of the speaker P assumed in the meeting space. Further, the focal position where the reflected wave of the three-dimensional sound collecting shape of the wall structure converges is preferably near the head of the speaker P assumed in the meeting space.

The sound source position corresponding to the focal position of the three-dimensional sound collecting shape of the wall structure can be set to infinity where the incident waves are parallel. At this time, the ideal three-dimensional sound collecting shape of the wall structure is a rotating paraboloid, which is a kind of quadratic curved surface of revolution. As described above, when the three-dimensional sound collecting shape of the wall structure is a rotating paraboloid and there are a plurality of speakers P facing the wall structure on the opposite side of the table 2, these multiple stories By efficiently converging the voice of the person P to the speaker P located with his / her back to the wall structure, the speaker P located with his / her back to the wall structure can easily hear the conversation.

Further, the sound source position corresponding to the focal position of the three-dimensional sound collecting shape of the wall structure may be near the assumed head of the speaker P located on the opposite side of the table 2 facing the wall structure. At this time, the ideal three-dimensional sound collecting shape of the wall structure is a spheroidal surface, which is a kind of quadratic curved surface of revolution. As described above, when the three-dimensional sound collecting shape of the wall structure is a spheroid, when two speakers P talk with each other sandwiching the table 2, the voice of one speaker P is spoken by the other. It can be efficiently converged on the person P.

<Table>
The table 2 has a guidance structure that guides the seating position of the speaker P. The induction structure in the compartmentalized structure of FIG. 1 is a notch 4 formed so that a human torso enters the top plate. As described above, since the table 2 has the guiding structure, the speaker P is guided to the position where the sound converges by the wall structure, and the conversation is more reliably prevented from leaking to the outside of the meeting space.

It should be noted that "formed so that the torso of a person can enter" is not limited to the one that the speaker P actually enters into the notch 5 and uses, and the speaker P is the side edge of the top plate of the table 2. It includes a shape facing the notch 5 in order to sit at an appropriate distance from the torso.
