Description

【考案の詳細な説明】本考案は卓上ピアノ、有鍵楽器のハンマーの打撃により発音する音源に関し、必要な音量と美しい音色が出るようにしたものである。本考案をその実施例である第一図、第二図、第三図によって説明する。第一図、第二図、第三図は音階順にならべた音源の１部分の実施例である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sound source produced by hitting a tabletop piano or a hammer of a keyed musical instrument with a necessary volume and a beautiful tone. The present invention will be described with reference to FIG. 1, FIG. 2, and FIG. Figures 1, 2 and 3 show an embodiment of a part of a sound source arranged in the order of scale.

図中（１）は音板、（２）は音板（１）の各々に穿たれた音板穴、（３）は材料はフェルト、ゴム等で振動体を柔かく保持する座板、（４）は座板（３）に穿たれた座板穴、（５）は座板穴（４）を介して音板（１）を挟むように櫛形状になった支持台、（６）は支持台（５）の櫛形部の各々に穿たれた穴又は溝で支持台溝、（７）は音板支持線で紐或は金属線にゴム等巻いたもので、図の如く音板穴（２）、座板穴（４）、支持溝（６）に通され音板（１）を保持する、（８）はハンマーで音板（１）を打撃する方向を示し縦方向、及び横方向を夫々Ａ、Ｂとする。 In the figure, (1) is a sound plate, (2) is a sound plate hole formed in each of the sound plates (1), (3) is a seat plate for softly holding the vibrating body with felt, rubber or the like, ( 4) is a seat plate hole formed in the seat plate (3), (5) is a support base that is comb-shaped so as to sandwich the sound plate (1) through the seat plate hole (4), and (6) is Holes or grooves formed in each of the comb-shaped portions of the support base (5) are support base grooves, and (7) is a sound plate support wire wound with a cord or a metal wire such as rubber. (2) Holds the sound plate (1) through the seat plate hole (4) and the support groove (6). (8) indicates the direction in which the sound plate (1) is struck by a hammer in the longitudinal direction and the lateral direction. The directions are A and B, respectively.

今この音源（１）にＡ方向よりハンマーで打撃を与えた場合、音板（１）は打撃の方向をそれと直角の方向即ちＢ方向の振動が同時に起ります、Ａ方向の振動は基音を構成する主たる音で、Ｂ方向の音は倍音として加わり合成されて１つの音となります。この場合Ｂ方向の音はＡ方向の音よりもはるかに低音で基音の防げとはならず又音板（１）の幅と厚さを適当に選ぶ事により本当にすんだ美しい音が得られます。在来の鉄琴、木琴、は今とは逆で基音を構成するＢ方向の音よりＡ方向の音が大層高いので、其の合成された音は高い管音入りの耳障りの不快な音として聞こえます。又本考案のようにする事により音源と音源の間隔を狭くする事が出来ますので鍵盤楽器の音源として最適です。（請求項１）又第四図は正面図、第五図は第四図の平面図、第六図は分解図で、二支点で音板（１）を支えるに当り、片方は第一図、第二図のように支持線（８）で支え、他方は支持線（８）を用いず、支持台溝（６）に直接座板（３）で音板（１）を包み挟むように貼り着け、そこに音板（１）を落し込んだもので、同様に説明出来ます。（請求項２） Now, when the sound source (1) is hit with a hammer from the A direction, the sound plate (1) simultaneously vibrates in the direction perpendicular to the striking direction, that is, the B direction. It is the main sound that composes, and the sound in the B direction is added as overtones and synthesized into one sound. In this case, the sound in the B direction is much lower than the sound in the A direction and does not protect the fundamental tone, and by selecting the width and thickness of the sound plate (1) properly, a truly beautiful sound can be obtained. I will. The sound of A direction is much higher than that of B direction which is the fundamental tone of the conventional xylophone and xylophone, so the synthesized sound is a harsh and unpleasant sound with a high pipe tone. Sounds like. Moreover, by making the present invention, the interval between sound sources can be narrowed, so it is ideal as a sound source for keyboard instruments. (Claim 1) Further, FIG. 4 is a front view, FIG. 5 is a plan view of FIG. 4, and FIG. 6 is an exploded view. When supporting the sound plate (1) at two fulcrums, one is the first view. As shown in FIG. 2, support the support plate (8) on the other side, without using the support line (8), wrap the sound plate (1) in the support base groove (6) directly with the seat plate (3). It is attached and the sound plate (1) is dropped on it, and the same explanation will appear. (Claim 2)
