Variable Qinchuan flute

Abstract

The invention discloses a variable Qinchuan flute, which is characterized in that a conventional Qinchuan flute is improved in design, and in order to relieve the playing burden and enable a player or a learner to better perform the emotion of music, the following modifications are made on a musical instrument: a rotary copper sleeve is arranged between a first hole and a fourth hole, so that the function of the conventional flute is reserved; when music similar to Qinchuan is required to be learned and played, the positions of the holes are changed, the copper sleeves are rotated, the sizes of the two holes are changed into an ellipse with the long axis of 6.9 mm and the short axis of 5.4 mm, the positions are moved, the central points of the holes move 7.6 mm towards the direction of the first hole, and the intonation of the three holes is influenced after the two holes are shrunk and move backwards, so that under the condition that the sizes of the three holes are not changed, the four holes of the net move 2.6 mm towards the direction of the four holes, and the intonation of the three holes is influenced. And intonation and performance of each hole are ensured.

Description

Technical Field

[0001] The invention relates to a variable Qinchuan flute. Background Art

[0002] When playing "Qinchuan Love", the full note of "Qinchuan Love" is "6(la)", that is, the simplified note is "6(la)", and the pitch of "1(do)" is very difficult to control the pitch and vibrato of the second hole of the conventional flute. Therefore, the applicant proposes further improvement on this basis and designs a variable Qinchuan flute to meet the needs of the existing market. Summary of the invention

[0003] The present invention aims to provide a variable Qinchuan flute that can solve the technical problem.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: A variable Qinchuan flute comprises a flute body, on which a blowing hole, a membrane hole, six holes, five holes, four holes, three holes, two holes, one hole, a fundamental tone hole, an auxiliary first hole and an auxiliary second hole are arranged in sequence, characterized in that a rotatable copper sleeve is arranged between the one hole and the four holes, the rotatable copper sleeve comprises an inner sleeve and an outer sleeve which are arranged to match each other, wherein the inner sleeve is fixed to the outside of the flute body, the outer sleeve can rotate relative to the inner sleeve, and two groups of hole structures are arranged on the outer sleeve, namely, a variable hole group one and a variable hole group two, the variable hole group one comprises two independent holes, which are respectively arranged to For hole two and hole three, the aperture specifications of the two independent holes are consistent with the aperture specifications of the corresponding hole two and hole three; the variable hole group two includes two independent small holes, and the two independent small holes are elliptical with a long axis of 6.9mm and a short axis of 5.4mm. The hole center of the small hole close to the first hole is moved 7.6mm toward the first hole. Since the second hole is reduced and moved back, it will affect the pitch of the third hole. Therefore, without changing the size of the three holes, the hole center of the small hole close to the fourth hole is moved 2.6mm toward the fourth hole to ensure the pitch and performance of each hole.

[0005] Compared with the prior art, the beneficial effects achieved by the present invention are: The present invention improves the design of a conventional Qinchuan flute. In order to reduce the burden of performance and allow performers or learners to better interpret the emotions of music, the following modifications are made to the musical instrument: a rotatable copper sleeve is installed between the first hole and the fourth hole, the function of the conventional flute is retained, and when it is necessary to learn and play music similar to "Qinchuan Love", the hole position is changed, the copper sleeve is rotated, the size of the second hole is changed to an ellipse with a long axis of 6.9 mm and a short axis of 5.4 mm, and the position is moved, the center point of the hole is moved 7.6 mm toward the first hole, and after the second hole is reduced and moved back, it will affect the pitch of the third hole, so without changing the size of the third hole, the net is moved 2.6 mm in the direction of the fourth hole to ensure the pitch and performance of each hole.

[0006] In addition to reducing the burden of performance, the beneficial effects of the variable Qinchuan flute include: it allows for easy switching between the Qinchuan flute and a regular flute on one flute. That is, the performer only needs to purchase one variable Qinchuan flute to have the functions of both the Qinchuan flute and a regular flute, which is in line with the concept of energy conservation and environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The accompanying drawings are used to provide further understanding of the present invention and constitute a part of the specification. They are used to explain the present invention together with the embodiments of the present invention and do not constitute a limitation of the present invention.

[0011] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0012] like Figure 1-Figure 3 As shown, the present invention discloses a variable Qinchuan flute, comprising a flute body 1, on which a blowing hole 2, a membrane hole 3, six holes 4, five holes 5, four holes 6, three holes 7, two holes 8, one hole 9, a fundamental tone hole 10, an auxiliary first hole 11 and an auxiliary second hole 12 are arranged in sequence, characterized in that a rotatable copper sleeve 13 is arranged between the one hole 9 and the four holes 6, the rotatable copper sleeve 13 comprises an inner sleeve and an outer sleeve 131 which are matched with each other, wherein the inner sleeve is fixed to the outside of the flute body 1, the outer sleeve 131 can rotate relative to the inner sleeve, and the outer sleeve 131 is provided with two groups of hole structures, namely, a variable hole group 1 132 and a variable hole group 2 133. 33, the variable hole group 132 includes 2 independent holes, corresponding to hole 2 and hole 3 respectively, and the aperture specifications of the 2 independent holes are consistent with the aperture specifications of the corresponding holes 2 and 3; the variable hole group 2 133 includes 2 independent small holes, and the 2 independent small holes are elliptical with a long axis of 6.9 mm and a short axis of 5.4 mm. The hole center of the small hole close to the first hole is moved 7.6 mm toward the first hole. Since the second hole is reduced and moved back, it will affect the pitch of the third hole. Therefore, without changing the size of the third hole, the hole center of the small hole close to the fourth hole is moved 2.6 mm toward the fourth hole to ensure the pitch and performance of each hole.

[0013] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
