Technical Field
[0001] The utility model relates to the technical field of musical instruments flutes, and more specifically to the technology of applying and adjusting flute membranes. Background Art
[0002] The flute is a very important instrument in traditional Chinese music. The bamboo flute that is now widely used was already in common use during the Han Dynasty. The first official record of adding a membrane to the flute was made by Liu Xi of the Tang Dynasty. As a distinctive feature of Chinese flutes and Western flutes, the flute membrane gives the flute a fresh, pure, bright and graceful tone, which is deeply loved by performers and listeners. Although the material and production of the flute and the flute membrane are very important to the flute's tone, the quality of the membrane installation has become a key factor in whether the best tone can be achieved.
[0003] The traditional method of applying the membrane to the flute is to first apply membrane glue around the membrane hole on the flute, then use the thumbs and index fingers of both hands to hold the prepared membrane sheet and slightly stretch it in the transverse direction of the membrane texture. The thumb of one hand presses the membrane tightly against one side of the membrane hole, and the other hand tightens the membrane and uses the thumb to apply the other end of the membrane to the other side of the membrane hole. Then, the thumbs of both hands press the two ends of the membrane to stretch outwards on both sides of the membrane hole to generate transverse tension until the membrane produces dense, uniform and fine transverse wrinkles on the membrane hole. These fine wrinkles can produce multiple overtones of different frequencies but in harmony with the original sound played when the gas in the flute tube vibrates, thus producing the unique timbre of the flute. The formation of these fine wrinkles is directly related to the size and direction of the force applied by the thumbs of both hands and the uniformity of the force applied forward and backward. Since this operation is performed at the membrane hole that has been coated with membrane glue, the membrane will be improperly tight or damaged if you are not careful. The quality of the membrane application will vary between different people and the same person at different times. Therefore, the membrane application technology has a large uncertainty. In addition, even if the flute membrane has been pasted, the lateral tension of the flute membrane will change with the change of ambient temperature and humidity and the increase of usage time, which will affect the sound quality of the flute. The correction method is usually to wet the flute membrane with water at the adhesive part and then adjust it. The tightness is not easy to control and it is easy to damage the flute membrane. These factors cause the instability of the flute timbre. The inconvenience caused by these uncertainties and instabilities to the players has, to a certain extent, affected the wider dissemination of Chinese flute art in China and the world. Therefore, whether for the convenience of flute players or for the wider dissemination of flute music, it is of great significance to solve the uncertainty and instability of flute membrane pasting. Although there have been attempts in recent years to produce fine wrinkles in the flute membrane by adjusting the longitudinal tension of the flute membrane [1], up to the present invention, there has been no technology that accurately adjusts the lateral tension of the flute membrane to produce fine wrinkles in the flute membrane and then accurately adjusts the timbre of the flute membrane. Utility Model Content
[0004] The utility model aims to use a device to imitate the physical principle and method of attaching and adjusting a flute membrane by human hands so that the process of installing and adjusting the flute membrane can be precisely controlled, thereby achieving an ideal acoustic effect of the flute membrane.
[0005] The technical solution of the utility model is a device for adjusting the lateral tension of a flute membrane, comprising an adjustment belt with an opening for sticking the membrane at a stretchable part, an adjustment plate connected to the adjustment belt and an adjustment screw for changing the distance between two adjustment plates.
[0006] The middle section of the aforementioned adjustment belt is stretchable, while the remaining section has no obvious stretchability.
[0007] The aforementioned adjusting plates have round holes at both ends, the round hole on one adjusting plate has no thread, and the round hole in the other adjusting plate has thread. The adjusting screw is a hand-turned screw that is easy to twist with fingers.
[0008] When the adjusting band is in a stretched state, the mechanical pressure exerted by the middle section of the adjusting band on the flute body causes the flute membrane to be non-adhesively covered on the flute membrane hole.
[0009] Compared with the prior art, the flute membrane is not fixed to the flute membrane hole by adhesive, but fixed to the opening of the adjustment belt. When the adjustment belt is installed, the flute membrane is covered on the flute membrane hole with the surface facing inward, so it is close to the flute membrane hole like the traditional flute membrane. Since the opening of the middle section of the adjustment belt is elastic, its expansion and contraction can cause the change of the transverse tension of the flute membrane. The elastic part of the adjustment belt is not elastic, so that it can accurately convert the change of the distance between the two adjustment plates into the change of the length of the elastic part of the adjustment belt, so that the adjustment of the transverse tension of the flute membrane is accurate and sensitive. The adjustment screw passes through the non-threaded hole on one adjustment plate and is screwed into the threaded hole on the other adjustment plate. As the screw is screwed into the threaded hole, the distance between the two adjustment plates will be shortened. Since the adjustment plate is directly connected to the end of the adjustment belt, the elastic area on the adjustment belt is stretched through the non-elastic area of the adjustment belt. Since the flute membrane is attached to the elastic area on the adjustment belt, the transverse tension of the flute membrane increases. Conversely, as the hand-turned screw is screwed out of the threaded hole, the transverse tension of the flute membrane will decrease. Two adjusting screws can independently adjust the tightness of the two sides of the adjusting belt so that the lateral tension of the diaphragm can be accurately adjusted in the longitudinal direction of the diaphragm hole.

Figure 4 As shown in the figure, insert the adjusting screw through the unthreaded round hole on the adjusting plate and then screw it into the threaded round hole on the other adjusting plate. When both thumb screws are screwed into the threaded holes, adjust the position of the adjusting strap to ensure that its opening is directly opposite the diaphragm hole. Then gently tighten the adjusting screw further to adjust the lateral tension of the diaphragm to produce tiny and uniform wrinkles. The performer can easily adjust the lateral tension of the diaphragm according to the sound effect of the test blowing. When the diaphragm needs to be replaced, remove the adjusting strap, remove the old diaphragm, and then install the new diaphragm according to the above process.
