(接上期)8.孔及音梁的制作:意大利对F孔的定位以及F孔与音梁之间的关系颇有研究,对于不同的琴型,不同的琴声音会作出不同的设计。例如,瓜式琴的F孔设计比较倾斜,便是因为瓜式琴中腰部开阔,为进一步增大中央琴码第一振动区的面积而考虑的。9.面、背板与侧板的粘和:在音板完成之后,要尽快的与侧框粘和,避免对整个音箱增加不必要的内在应力,抑制整个音箱的振动。整个音箱除了F孔,是一个密和整体,这样才能让音箱的振动达到同步。音箱内空气容量的大小对琴的音量起到了制约性的作用。
(Continued) 8. Hole and sound beam production: Italy F hole positioning and F hole and the relationship between the sound beam quite a study, for different types of piano, different piano sounds will be made of different designs. For example, the melon piano F hole design is more inclined, it is because the melon open waist, in order to further increase the area of the central piano code the first vibration area to consider. 9. Surface, back and side panels of the sticky: After the soundboard is completed, as soon as possible with the side frame sticky, to avoid unnecessary increase of the entire speaker of the intrinsic stress, inhibit the vibration of the entire speaker. In addition to the entire F speaker hole, is a close and overall, so that the vibration of the speaker can be synchronized. The size of the air volume within the speaker played a restraining role on the volume of the piano.
