Description

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

  Meeting spaces used for conferences and business negotiations are formed by installing partitions in the room. When discussing trade secrets, personal information, etc., it is desirable to prevent the conversation content from leaking 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 externally (see JP 2012-82582 A). .

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

JP 2012-82582 A

  In view of the above inconveniences, an object of the present invention is to provide a wall structure and a section structure that can make it difficult for conversation contents to be transmitted to the outside without increasing ambient environmental noise.

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

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

  The quadratic curve rotation surface may be a paraboloid of revolution.

  The quadratic curve rotation surface may be a spheroid.

  The table may have a guiding structure for guiding a seating position.

  Note that the “wall” is not limited to an upright wall, and includes a wide range of things having a surface that divides a space, such as a ceiling and a floor. “Three-dimensionally converged shape” 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 locus of the reflected wave at these two or more points Means a shape drawn in two or more planes. Further, the “second-order curve rotation surface”, “rotation paraboloid”, and “spheroid surface” may be surfaces approximated by a plurality of planes or spherical surfaces. In addition, “a part of the quadratic curve rotation surface” means one that does not exist over the entire circumference around the central axis. Further, the “sitting position” is not limited to the position where the speaker is seated, but includes the position where the speaker stands when standing up and talking.

  The wall structure and the section structure of the present invention have a sound collecting shape that reflects and converges sound waves incident from the front, so that even if a conversation with a relatively small voice is performed in front of the wall structure, Can be heard relatively easily. For this reason, the voice of the speaker is naturally reduced, and it is prevented that the voice is leaked outside and the conversation content is heard by a third party.

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

  Thus, 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 other party's voice, and the voice is naturally reduced. For this reason, without increasing the environmental noise around the meeting space, it is possible to prevent the voice of the speaker P from leaking outside the meeting space and listening to the contents of the conversation by a third party.

  As the three-dimensional sound collection shape of the wall structure, a quadratic curve rotation surface, a part of the quadratic curve rotation surface, or a combination of a part thereof is preferably used. This quadric curve rotation surface may be approximated by arranging a plurality of planes side by side.

It is preferable that the rotation axis of the quadric curve rotation surface 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. 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 wave is parallel. At this time, the ideal three-dimensional sound collection shape of the wall structure is a paraboloid of revolution that is a kind of quadratic curve rotation surface. Thus, when the three-dimensional sound collection shape of the wall structure is a paraboloid of revolution, when there are a plurality of speakers P facing the wall structure on the opposite side of the table 2, the plurality of stories By efficiently converging the voice of the person P to the speaker P positioned with the back toward the wall structure, the speaker P positioned with the back toward 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 positioned opposite to the wall structure on the opposite side of the table 2. At this time, the ideal three-dimensional sound collection shape of the wall structure is a spheroidal surface which is a kind of quadratic curve rotation surface. Thus, when the two speakers P have a conversation with the table 2 in between because the three-dimensional sound collection shape of the wall structure is a spheroid, the voice of one speaker P The user P can be efficiently converged.
