<p>PURPOSE:To improve the directionality of sound wave vibration and also to reduce the distortion of sound propagated from a floor or a supporting base by being a bottom part away from the floor and the supporting base by a prescribed distance and securing a load carrier condition approximate to a point-supporting and a line-supporting. CONSTITUTION:This supporting matter is constituted by combining a base plate 11 whose bottom surface is abutted on the foor surface, a load carrier member 12A forming one body with the base plate 11 and consisting of an one-end supporting beam or both-ends supporting beams forming the supporting point of the musical instrument or the speaker while keeping the prescribed distance from the floor surface F.L at the upper ward of the base plate 11 and a sound quality adjusting member 13 attached exchangably to the supporting point with a burrying method. In this way, a supporting body in which the lower end surface of the musical instrument or the speker is come into surface-contact relatively narrow in contact area with the upper surface of the sound quality adjusting member 13, further preferably, into point-contact or line-contact therewith is formed. Thus, since the main body of the musical instrument and the speaker are away from the floor surface by the prescribed distance the turbulance of wave forms of sound wave vibration and the floor vibration propagated from the musical instrument or the speaker is reduced.</p> |
