The conversation support structure 1 according to the first embodiment is assumed to support a conversation in which the voice of a first person P1, who is a speaker, is transmitted to a second person P2, who is a listener. . A first paraboloid 21 is provided behind the first person P1, and the focal point F of the first paraboloid 21 is set to be located in front of the first person P1.

Note that the first paraboloid 21 may be provided on a part of the wall surface. Moreover, the material of the first paraboloid 21 is not particularly limited as long as it is a surface that reflects sound.

A flat first partition plate 31 is provided at the midpoint between the focal point F of the first paraboloid 21 and the position (approximate position) of the mouth of the first person P1 seated on the first seat 11. There is. That is, the distance between the mouth position of the first person P1 seated on the first seat 11 and the first partition plate 31 is d, and the focal point of the first partition plate 31 and the first paraboloid 21 is d. The distance between F and F is also d. Here, the thickness of the first partition plate 31 is ignored.

In the conversation support structure 1 according to the present invention, the first paraboloid 21, the first seat 11, and the first partition plate 31 are integrated, so that the first paraboloid 21 and the first The positional relationship between the first seat 11 and the first partition plate 31 may be fixed. Of course, the first paraboloid 21, the first seat 11, and the first partition plate 31 may be arranged in a layout based on the present invention as appropriate without fixing the above-mentioned positional relationship.

The two opposing main surfaces of the first partition plate 31 extend in the depth direction of the paper. The first partition plate 31 may be made of any material as long as it is a flat plate that reflects sound, but it is preferably made of a transparent material such as an acrylic plate. The first partition board 31 functions as a countermeasure against infectious diseases by separating the first person P1 and the second person P2.

The first person P1 seated on the first seat 11, the first partition plate 31, and the focal point F of the paraboloid of the first paraboloid 21 are on the axis of the paraboloid (the axis of the paraboloid). It is laid out so that it is lined up with. Moreover, it is preferable that the main surface of the first partition plate 31 and the axis of the paraboloid are perpendicular to each other.

If the vertical direction of the plane of FIG. 1 is defined as the width direction, the width (W1) of the first paraboloid 21 is set to be larger than the width (W2) of the first partition plate 31. Specifically, the first paraboloid 21 extends outward from the point of intersection with a straight line (dotted chain line in FIG. 1) that passes through the outer edge of the first partition plate 31 and is parallel to the axis of the paraboloid. It has a width.

FIG. 3 is a diagram explaining the principle of functioning of the conversation support structure 1 according to the present invention.

As shown in FIG. 3, the sound emitted from the mouth of the first person P1 who is the speaker enters the first partition plate 31 and is reflected to the rear of the first person P1.

The mouth of the first person P1 is a real sound source. In the conversation support structure 1 according to the present invention, the first partition plate 31 is arranged at the midpoint between this real sound source and the focal point F of the first paraboloid 21. The position of the virtual image of the real sound source with respect to the first partition plate 31 corresponds to the position of the focal point F of the first paraboloid 21.

That is, due to the geometrical characteristics of the first paraboloid 21, the sound emitted from the actual sound source is reflected by the first partition plate 31 and the first paraboloid 21, and then is transmitted to the first person P1 as shown in the figure. It will propagate in a straight line forward.

Here, the sound that propagates linearly differs from normal speech that propagates radially from the sound source (the mouth of the first person P1), in which the sound pressure level does not decrease with distance, that is, there is no distance attenuation. Therefore, in the conversation support structure 1 according to the present invention, the second person P2 seated on the second seat 12 can hear the voice clearly even if the second person P2 is at a distant position.

As described above, the conversation support structure 1 according to the present invention supports conversation with the structure consisting of the first paraboloid 21 and the first partition plate 31 without using a microphone or a speaker. According to the conversation support structure 1, problems such as howling do not occur.
