旧式二胡由于音量小,愈来愈不能适应民族乐队日益发展的需要,因此,有不少的同志从不同的角度探索着扩大二胡音量的途径。十多年前曾进行过喇叭筒、竹质琴筒、铜质琴筒、无音窗琴筒及筒边开窗等等扩大二胡音量的试验;并且有的同志还利用半导体、电子管等电扩音装置,这些努力,大大地丰富了我们的实践内容。对在扩大二胡音量这个问题的认识的道路上,通过不断实践,寻求着更科学更理想的方法,很有裨益。
Because of the small volume of the old erhu, they can not meet the growing needs of the national band more and more. Therefore, many comrades have explored ways to expand the volume of erhu from different angles. More than ten years ago, there were experiments on expanding the volume of the erhu, such as the horn, the bamboo cylinder, the copper cylinder, the windowless cylinder and the window on the cylinder side. Some comrades also used the electric expansion of semiconductors and electron tubes Sound devices, these efforts have greatly enriched our practice content. On the road to understanding the issue of expanding the volume of erhu, it is useful to seek more scientific and desirable ways through constant practice.
