Abstract
Description
Technical Field
[0001] The invention relates to a harpsichord flute. Background Art
[0002] The music scores of bamboo flute are mainly notated in the first key, and due to the limitation of the range of the bamboo flute itself, the same flute needs to change key when playing different music. For example, the D-key flute of the song "Happy Song" is played in "5 (sou)", and the song "Er Fan" is played in "6 (la)". Then the problem comes. Almost all flutes on the market are made to arrange the scale in "5 (sou)". When it is necessary to play with fingerings such as "2 (re)", "3 (mi)" and "6 (la)", some basic notes are achieved by pressing half holes. This is very difficult for learning and playing, especially for beginners. Early learning is very unfavorable for the establishment of intonation. Therefore, we see that many students are solving this intonation problem when entering university or even at work, and intonation has become a pain point in bamboo flute learning. Therefore, the applicant proposes further improvements on this basis and designs a cyclotron flute to meet the needs of the existing market. Summary of the invention
[0003] The present invention aims to provide a harpsichord flute which can solve the technical problem.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: A cyclotron 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, and the feature is that a first variable device is arranged between the four holes and the six holes, and a second variable device is arranged between the one hole and the four holes.
[0005] To further optimize the present invention, the first variable device is a rotatable copper sleeve, the rotatable copper sleeve includes an inner sleeve and an outer sleeve that are matched with each other, wherein the inner sleeve is fixed to the outside of the flute body, and the outer sleeve can rotate relative to the inner sleeve, and the outer sleeve is provided with two holes, namely variable hole one and variable hole two, the aperture specification of the variable hole one is consistent with the aperture specification of the fifth hole, and the variable hole two is a small flute hole of a minor second.
[0006] As a further optimization of the present invention, the center point of the variable hole 2 moves 4 mm toward the first hole.
[0007] As a further optimization of the present invention, the second variable hole is an ellipse with a major axis of 7.1 mm and a minor axis of 5.5 mm.
[0008] The present invention is further preferred, wherein the second variable device is a rotatable copper sleeve, the rotatable copper sleeve comprises an inner sleeve and an outer sleeve which are matched with each other, wherein the inner sleeve is fixed to the outside of the flute body, and the outer sleeve can rotate relative to the inner sleeve, and the outer sleeve is provided with two groups of hole structures, namely variable hole group one and variable hole group two, the variable hole group one comprises two independent holes, corresponding to hole two and hole three respectively, and the aperture specifications of the two independent holes are consistent with the aperture specifications of the corresponding holes two and three; the variable hole group two comprises two independent small holes, and the two independent small holes are elliptical with a major axis of 7.1 mm and a minor axis of 5.5 mm.
[0009] The present invention is further optimized, in which the center of the small hole close to the first hole of the two independent small holes 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 third hole, the 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.
[0010] Compared with the prior art, the beneficial effects achieved by the present invention are: In the Chinese music theory system, the term "xuangong" refers to the conversion of pitch, that is, the pitch is changed by changing the position of the gong sound. The xuangong flute changes the position of the gong sound by rotating the device, which is a double entendre.
[0011] The present invention improves the design of a conventional bamboo flute. A rotating copper sleeve is installed between the first hole and the fourth hole, and the function of the conventional flute is retained. When the second hole needs to be tuned to a minor second, the hole position is changed. The copper sleeve is rotated, and the size of the second hole is changed to an ellipse with a long axis of 7.1 mm and a short axis of 5.5 mm, and the position is moved. The center point of the hole moves 7.6 mm toward the first hole. After the second hole is reduced and moved backward, the pitch of the third hole is affected. Therefore, without changing the size of the third hole, the net moves 2.6 mm in the direction of the fourth hole to ensure the pitch and performance of each hole. A rotating copper sleeve is installed between the fourth hole and the sixth hole, and the function of the conventional flute is retained. When the fifth hole needs to be tuned to a minor second, the hole position is changed. The copper sleeve is rotated, and the size of the fifth hole is changed to an ellipse with a long axis of 7.1 mm and a short axis of 5.5 mm, and the position is moved. The center point of the hole moves 4 mm toward the first hole. The change of the size and position of the fifth hole does not affect the pronunciation of the sixth hole, so the sixth hole does not need to be changed. BRIEF DESCRIPTION OF THE DRAWINGS
