Abstract

The invention relates to a method of manufacturing a bamboo flute-used flute diaphragm. The method comprises the following steps: 1) a micronano multilevel-structure polysulfone fiber diaphragm is prepared; 2) porous molecular sieve soakage is carried out; and 3) flute diaphragm processing is carried out. The manufactured flute diaphragm can enhance the structural strength of the flute diaphragm, the problems that the existing flute diaphragm is likely to break and water can be solved, and the industrial production of the flute diaphragm is realized.

Description

technical field [0001] The invention belongs to the field of musical instrument manufacturing, and in particular relates to a bamboo flute membrane. Background technique [0002] The Chinese bamboo flute has a beautiful and beautiful sound. A bamboo flute can produce a pleasing sound, out of high-quality bamboo and superb performance techniques, there is another very critical factor, that is the flute membrane. Mr. Yu Xunfa, a famous flute player, once said: "The membrane of the bamboo flute is the second life of the bamboo flute." The unique and charming tone of the Chinese bamboo flute comes from this thin membrane. [0003] Dimo is a very important part of the flute, without it, it would be difficult for the flute to play accurate scales. The membrane of the flute is often attached to the membrane hole of the flute, and the sound is produced by the vibration of the airflow when playing. [0004] Dimo, this kind of film has two kinds of natural and artificial. [0005]...
