二胡琴筒上的蟒皮面,在适当的琴马压力下才能产生良好的振动。由于制作工艺和使用材料的差异,每一把二胡都有区别于其它二胡的自身特性,所需的琴马压力也不尽相同。本人认为,可以通过调节琴马压力去改变蟒皮的振动状态,达到在一定限度内调整音质的目的。为此,我为二胡设计了一种“可调系弦器”,用来调节琴马对蟒皮面的压 Ebony python on the python surface, under the appropriate piano pressure to produce good vibration. Due to the difference between the production process and the use of materials, every erhu has its own characteristics that are different from other erhu, the pressure required by the bridge are not the same. I think that by adjusting the pressure on the bridge to change the vibration of Python skin, to a certain extent, the purpose of adjusting the sound quality. To this end, I designed for the Erhu a “adjustable string system”, used to adjust the piano on the Python python pressure
