SOUND SPACE BUILDING STRUCTURE THAT PRODUCES SOUND AMPLIFICATION AND EXCELLENT REVERBERATION BY INDUCING SOUND-FOCUSING WITHOUT AMPLIFIER EQUIPMENTS

摘要

The present invention is an upper open-type building structure constructed and installed on a reference floor surface, with one point on the reference floor surface as a center point in a plane, and erected at predetermined intervals on the reference floor surface from a center point on the reference floor surface A plurality of acoustic induction wing plates disposed radially at a distance and installed to form a planar curved frame as a whole; An acoustic reflective wall connected to the acoustic induction wing plate and installed in a plane on the reference floor to have a same curved shape on the plane as the acoustic induction wing plate and installed to form a constant acoustic space therein; The roof top viewing floor is installed to be spaced apart from the reference floor by a predetermined height, and is extended from the top of the acoustic reflection wall in a direction opposite to the center point on the plane of the reference floor. As a columnar member having a cross-sectional shape having a long side and a short side as a whole, the acoustic-inducing wing plates are installed so as to form a radial arrangement with the long-side direction of the cross-section facing the center point in the plane of the reference bottom surface, respectively. It is characterized in that all or part of the cross section of the acoustic induction wing plate is installed so as to protrude a certain length from the surface of the acoustic reflection wall toward the center point on the plane. According to the acoustic space building structure of the present invention as described above, the sound generated on the stage during the outdoor event is amplified by sound focusing and resonance phenomenon, so that pure sound can be heard with satisfactory volume without additional sound equipment. In addition, the sound reflection, sound absorption, and interference in the quality of sound are in an appropriate balance, thereby creating an optimal reverberation that is clear and transparent.
