Description

The present invention relates to partitions.

A meeting space used for meetings, business negotiations, etc. is formed by installing partitions in the room. When discussing trade secrets, personal information, etc., it is desirable to prevent the content of the conversation from leaking out of 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 content of the conversation in the meeting space cannot be heard from the outside (see Japanese Patent Application Laid-Open No. 2012-82582). .

However, when masking sound is used, there arises a problem that ambient environmental noise increases. In other words, when a plurality of business meeting spaces are provided adjacently, there is a masking sound that makes it difficult to hear the conversation in the adjacent meeting space, so there is a risk that it will be necessary to speak in a relatively loud voice in the meeting space.

JP 2012-82582 A

SUMMARY OF THE INVENTION In view of the above inconvenience, it is an object of the present invention to provide a partition that makes it difficult for the content of a conversation to be transmitted to the outside without increasing ambient environmental noise.

The invention made to solve the above problems is a partition that divides a room into one or more meeting spaces, comprising a housing material and a waist wall that supports the housing material from below, A sound collecting shape that reflects and converges incident sound waves is formed on one surface of the housing material.

The sound collection shape may be a shape that reflects and three-dimensionally converges sound waves incident from the front.

The sound collection shape may be a quadratic curve surface of revolution, a part of this quadratic curve surface of revolution, or a combination of parts thereof.

The quadric surface of revolution may be a paraboloid of revolution.

The quadratic surface of revolution may be an ellipsoid of revolution.

It should be noted that the term “wall” is not limited to an upright wall, but is a concept that includes a wide range of objects having surfaces that divide space, such as ceilings and floors. "Three-dimensionally converging shape" means that the reflected waves at two or more points on the surface reach the same point for the sound waves incident from the same point, and the trajectories of the reflected waves at these two or more points means a shape drawn on two or more planes. Further, the "quadratic surface of revolution", "paraboloid of revolution" and "ellipsoid of revolution" may be surfaces approximated by a plurality of planes or spherical surfaces. Also, "a part of the quadratic curve surface of revolution" means a part that does not exist over the entire circumference around the central axis. Also, the "seating position" is not limited to the position where the speaker sits, but includes the position where the speaker stands when speaking while standing.

In the partition of the present invention, the wall structure has a sound collection shape that reflects and converges sound waves incident from the front, so that even if a person speaks in a relatively low voice in front of the wall structure, the voices of each other are compared. can be easily heard. As a result, the speaker's voice is naturally lowered, preventing the content of the conversation from being heard by a third party due to the leakage of the voice to the outside.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[First embodiment]
A partitioned structure according to the first embodiment of the present invention shown in FIGS. The partitioned structure forms a meeting space by arranging it on the floor as shown. Specifically, by separating the space near the table 2 from the surrounding space by the partition 1, a meeting space is defined in the room.

The meeting space formed by the partitioned structure of this embodiment, as shown in FIG. It can also be used for conversations by speaker P and for using teleconferencing systems.

<Partition>
The partition 1 comprises a housing material 3 with a wall structure according to another embodiment of the invention. The partition 1 can be configured to have a waist wall portion 4 that holds the housing material 3 at a constant height and partitions the lower part of the housing material 3 .

(housing materials)
The wall structure of the housing material 3 has one or a plurality of sound collecting shapes on the front surface (the surface on the table 2 side) for reflecting and converging sound waves incident from the front. This sound collection shape is preferably a sound collection shape that reflects and three-dimensionally converges sound waves incident from the front.

In this way, the sectioned structure has the housing materials 3 having the wall structure, so that the speaker P who converses in the meeting space can easily hear the other party's voice, and the voice is naturally reduced. Therefore, it is possible to prevent the voice of the speaker P from leaking out of the meeting space and the contents of the conversation from being heard by a third party without increasing the environmental noise around the meeting space.

As the three-dimensional sound collection shape of the wall structure, a quadratic curve surface of revolution, part of the quadratic curve surface of revolution, or a combination of parts thereof is preferably used. This quadratic 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 surfaces of revolution, it is preferable that the plurality of quadratic surfaces of revolution are coaxial. It is preferable that the rotation axis of the quadratic curved surface of rotation adopted for the three-dimensional sound collecting shape of the wall structure is a horizontal axis passing through the head of the speaker P assumed in the meeting space. Moreover, the focal position where the reflected waves of the three-dimensional sound collection shape of the wall structure converge 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 collection 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 paraboloid of revolution, which is a kind of quadratic curved surface of revolution. In this way, since the three-dimensional sound collecting shape of the wall structure is a paraboloid of revolution, when a plurality of speakers P are present on the opposite side of the table 2 and face the wall structure, the plurality of speakers P are arranged. By efficiently converging the voice of the person P on the speaker P who is positioned with his back to the wall structure, the speaker P who is positioned with his back to the wall structure can easily hear the conversation.

Also, the sound source position corresponding to the focal position of the three-dimensional sound collection shape of the wall structure may be near the assumed head of the speaker P who is positioned on the opposite side of the table 2 and faces the wall structure. At this time, the ideal three-dimensional sound collection shape of the wall structure is an ellipsoidal surface of revolution, which is a kind of surface of revolution of a quadratic curve. In this way, when two speakers P have a conversation with the table 2 sandwiched by the three-dimensional sound collection shape of the wall structure being a spheroid, the voice of one speaker P is It is possible to efficiently converge on the person P.

<Table>
The table 2 has a guiding structure that guides the seating position of the speaker P. The guiding structure in the sectional structure of FIG. 1 is a notch 4 formed in the top plate so that the human torso can enter. Since the table 2 has the guide structure, the wall structure guides the speaker P to a position where the sound converges, thereby more reliably preventing the conversation from leaking out of the meeting space.

It should be noted that "formed so that a person's torso can be inserted" is not limited to the case where the speaker P actually enters into the notch 5 for use, and the speaker P is not limited to the case where the speaker P is placed on the side edge of the top plate of the table 2. It includes a shape to face the notch 5 to seat properly spaced from.
