Split-type adjustable huqin pronunciation membrane unit

Abstract

The invention relates to a split type adjustable sound emitting diaphragm unit for a Huqin. According to the split type adjustable sound emitting diaphragm unit, the resonant box of the Huqin is divided into two parts, wherein the front part is a sound emitting diaphragm unit, and the back part is a cylinder, and the sound emitting diaphragm unit and the cylinder are assembled together so as to manufacture the resonant box; besides a fixed sound emitting diaphragm, the sound emitting diaphragm unit is provided with a tension adjustment mechanism of the sound emitting diaphragm; a pushing ring frame is arranged in a sound emitting diaphragm frame of the sound emitting diaphragm unit; the sound emitting diaphragm is arranged before the sound emitting diaphragm frame and covers the pushing ring frame; and the sound emitting diaphragm is fixed to the periphery of the sound emitting diaphragm frame; the sound emitting diaphragm frame is provided with a boss; the boss is provided with a nut; a screw is arranged in the nut in a matched manner; and the pushing ring frame is provided with a boss which is corresponding to the screw. With the split type adjustable sound emitting diaphragm unit for the Huqin adopted, standardized production and maintenance can be benefitted; the problem of the looseness and droop of the sound emitting diaphragm can be effectively solved. The split type adjustable sound emitting diaphragm unit is suitable for replacing sound emitting diaphragms made of python skin synthetic materials.

Description

technical field [0001] The present invention relates to stringed musical instruments, especially "split-type adjustable huqin sounding membrane unit", which mainly resonates with traditional huqin, such as erhu, jinghu, banhu and other bow hairs sandwiched between inner and outer strings Box improvements. Background technique [0002] Chinese patent application number: 201020269136.X, "Erhu with adjustable skin tension" proposes: one end of the inner side of the qin tube close to the skin is installed with the inner side of the qin tube, which is suitable for the size and shape of the qin tube, and can be moved along the qin tube inside the qin tube. A push ring whose inner wall moves axially, one end of the push ring presses against the inner side of the skin, and the other end presses against the screw end of the bolt through a bolt seat fixed on the push ring. The bolts are mounted on the [0003] On the bolt seat fixed on the inner side of the piano tube. Chinese pate...

Problems solved by technology

Both of the above-mentioned patent applications can adjust the tension of the huqin sounding membrane and play a role in adjusting the timbre, but the common point of these two methods is that the sounding membrane, the adjustment mechanism and the piano tube are made as a whole. Difficult, inconvenient to adjust, and the sound film and the piano tube are not interchangeable, which is not conducive to standardized production and maintenance
