钢琴键盘机械是一个相互连接的杠杆系统,它的作用是将弹奏者手指的运动能量传送给琴弦,引起琴弦的振动而发出声音。因此,一要求键盘机械灵敏度好,无杂音,各零件的运动位置准确,相接触的零部件在相对运动中其触点不得产生滑动,并具备优良舒适的触感。为满足这些要求,需对其各部件的尺寸进行精确计算、设计和加工制造。数百年来,经过多少代人的努力,现在已形成了几类特定规格、效果良好的键盘机械设计,但尚未见到令人信服的设计理论。笔者在工作实践中,对键盘机械进行大量的研究,并有一定收获。下面以立式钢琴为
Piano keyboard machine is a lever system connected to each other, its role is to move the player’s finger kinetic energy transmitted to the strings, causing the strings vibrate and make a sound. Therefore, a keyboard mechanical sensitivity requirements are good, no noise, the parts of the movement position is accurate, contact with the parts in the relative movement of the contacts shall not produce sliding, and have excellent comfort and feel. In order to meet these requirements, the dimensions of each component must be accurately calculated, designed and manufactured. For hundreds of years, after generations of hard work, several well-defined keyboard mechanical designs have now been developed, yet no convincing design theory has been seen. I work in practice, the keyboard a lot of research machinery, and have some gains. Below the vertical piano for
