For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] The improved oboe will be further described in detail below with reference to the drawings.

[0031] In combination with the drawings Figures 1-10 The utility model is introduced in detail.

[0032] An improved oboe, comprising a whistle piece 1, a core 2, an oboe rod 3 and an oboe bowl 4, wherein the whistle piece 1 is inserted at the top end of the core 2, the core 2 comprises a core body 5, an air disc 6 and a position limiter 7. The air disc 6 is detachably connected with the upper part of the core body 5, which is convenient for replacement and maintenance; the position limiter 7 is arranged at the lower part of the core body 5 and is used for limiting the position of the core body 5 in the oboe rod 3. The core body 5 below the position limiter 7 is inserted into the top end of the oboe rod 3, which ensures the stable connection between the core 2 and the oboe rod 3.

[0033] Further, the upper end inner diameter of the oboe rod 3 is 10mm, and the lower end inner diameter is larger than that of the same type of oboe, so as to adapt to different blowing requirements. The overall length of the oboe rod 3 is smaller than that of the same type of oboe rod 3, so that the performer is more comfortable when holding and playing. At the same time, the pitch hole spacing on the oboe rod 3 is also smaller than that on the same type of oboe rod 3, so that the pitch is more accurate and the playing effect is better.

[0034] The oboe bowl 4 is detachably connected with the lower end of the oboe rod 3, so that the performer can replace oboe bowls 4 of different sizes according to the playing requirements.

[0035] As a preferred scheme of the utility model, the core body 5 is a hollow circular truncated cone tube, the upper end inner diameter is 3.6mm, the outer diameter is 4mm, the lower end inner diameter is 8mm, and the outer diameter is 9mm. The length between the upper end and the lower end of the core body 5 can be adjusted according to different types and playing requirements, such as 50mm, 48mm or 38mm, etc.

[0036] In the design of the oboe rod 3, the front surface is sequentially provided with a first pitch hole 8, a second pitch hole 9, a third pitch hole 10, a fourth pitch hole 11, a fifth pitch hole 12, a sixth pitch hole 13, a seventh pitch hole 14 from top to bottom, and the back surface is provided with an eighth pitch hole 15. The distance between each pitch hole and the top end of the oboe rod 3, as well as the length and lower end inner diameter of the oboe rod 3 can be adjusted according to different types and playing requirements, so as to adapt to different playing styles and music pieces.

[0037] The specific implementation process of the improved oboe is as follows:

[0038] I. For the medium pitch range.

[0039] The descending B tone is essential. At present, the largest amount of use. The use amount of C tone and B tone is small, the reason is that although the oboe of these two tones is medium pitch oboe, he cannot reach the effect of medium pitch oboe, and still has the feeling of high pitch oboe, the sound is relatively sharp. Three oboes of medium pitch range. Great changes have been made.

[0040] The method and position of the change: first, the whistle piece 1 and the core 2 are unified. This unified range. Span three pitch ranges, medium pitch oboe, bass oboe and super bass oboe, all use one whistle piece 1 and core 2. Really save time, effort and money, especially practical and easy to use. The overall size of the three oboes of medium pitch range is shortened. This effect is to make the oboe sound brighter. The shorter the better. The inner diameter of the oboe is optimally adjusted. The inner diameter is adjusted as a whole. Figures 4-10 There are specific data.

[0041] Example 1: descending B tone oboe

[0042] Combined with the Figure 4The improved version of this suona has the following improvements to its suona rod 3: the distance between the first tone hole 8 and the top of the suona rod 3 is 50mm, the distance between the second tone hole 9 and the top of the suona rod 3 is 83mm, the distance between the third tone hole 10 and the top of the suona rod 3 is 102mm, the distance between the fourth tone hole 11 and the top of the suona rod 3 is 143mm, the distance between the fifth tone hole 12 and the top of the suona rod 3 is 173mm, the distance between the sixth tone hole 13 and the top of the suona rod 3 is 202mm, the distance between the seventh tone hole 14 and the top of the suona rod 3 is 237mm, the distance between the eighth tone hole 15 and the top of the suona rod 3 is 65mm, the length of the suona rod 3 is 300mm, and the inner diameter of the lower end of the suona rod 3 is 25mm.

[0043] Example 2: B-key suona

[0044] Combined with appendix Figure 5 The improved version of this suona has the following improvements to its suona rod 3: the distance between the first tone hole 8 and the top of the suona rod 3 is 50mm, the distance between the second tone hole 9 and the top of the suona rod 3 is 80mm, the distance between the third tone hole 10 and the top of the suona rod 3 is 107mm, the distance between the fourth tone hole 11 and the top of the suona rod 3 is 138mm, the distance between the fifth tone hole 12 and the top of the suona rod 3 is 167mm, the distance between the sixth tone hole 13 and the top of the suona rod 3 is 193mm, the distance between the seventh tone hole 14 and the top of the suona rod 3 is 224mm, the distance between the eighth tone hole 15 and the top of the suona rod 3 is 63mm, the length of the suona rod 3 is 282mm, and the inner diameter of the lower end of the suona rod 3 is 28mm.

[0045] Example 3: C-key Suona

[0046] Combined with appendix Figure 6 The improved version of this suona has the following improvements to its suona rod 3: the distance between the first tone hole 8 and the top of the suona rod 3 is 47mm, the distance between the second tone hole 9 and the top of the suona rod 3 is 73mm, the distance between the third tone hole 10 and the top of the suona rod 3 is 100mm, the distance between the fourth tone hole 11 and the top of the suona rod 3 is 125mm, the distance between the fifth tone hole 12 and the top of the suona rod 3 is 157mm, the distance between the sixth tone hole 13 and the top of the suona rod 3 is 177mm, the distance between the seventh tone hole 14 and the top of the suona rod 3 is 205mm, the distance between the eighth tone hole 15 and the top of the suona rod 3 is 60mm, the length of the suona rod 3 is 263mm, and the inner diameter of the lower end of the suona rod 3 is 25mm.

[0047] II. For the low-frequency range.

[0048] Low-pitched music is primarily used in somber and melodious funeral songs and operas. It is also used sparingly in solo pieces.

[0049] Mostly played in A flat. G sharp is less used because the distance between the holes is too big and needs long time to practice. But G sharp and D can be played together. So many people practice the big holes to play the solo together. So from the low range, the distance between the holes is solved. On the base of the small holes, the super small holes are designed again.

[0050] The adjustment part and method: the reed 1 and the core 2 are unified with the middle range. The overall size of the suona is shortened to make the sound brighter. The position of the sound hole is reduced. The performer can play the low suona without separate practice. The taper of the inner diameter of the suona is adjusted to match the sound hole and the reed 1 and the core 2 in the best state. The overall inner diameter is increased to achieve the effect of high sound transmission, full middle sound and rich low sound.

[0051] Example 4: A flat suona

[0052] Combined with the Figure 7 The improved suona of this model, the suona rod 3 is improved as follows: the distance between the first sound hole 8 and the top end of the suona rod 3 is 75mm, the distance between the second sound hole 9 and the top end of the suona rod 3 is 112mm, the distance between the third sound hole 10 and the top end of the suona rod 3 is 135mm, the distance between the fourth sound hole 11 and the top end of the suona rod 3 is 167mm, the distance between the fifth sound hole 12 and the top end of the suona rod 3 is 197mm, the distance between the sixth sound hole 13 and the top end of the suona rod 3 is 226mm, the distance between the seventh sound hole 14 and the top end of the suona rod 3 is 260mm, the distance between the eighth sound hole 15 and the top end of the suona rod 3 is 90mm, the length of the suona rod 3 is 336mm, and the inner diameter of the lower end of the suona rod 3 is 25.5mm.

[0053] Example 5: G sharp suona

[0054] Combined with the Figure 8 The improved suona of this model, the suona rod 3 is improved as follows: the distance between the first sound hole 8 and the top end of the suona rod 3 is 88mm, the distance between the second sound hole 9 and the top end of the suona rod 3 is 132mm, the distance between the third sound hole 10 and the top end of the suona rod 3 is 159mm, the distance between the fourth sound hole 11 and the top end of the suona rod 3 is 192mm, the distance between the fifth sound hole 12 and the top end of the suona rod 3 is 224mm, the distance between the sixth sound hole 13 and the top end of the suona rod 3 is 248mm, the distance between the seventh sound hole 14 and the top end of the suona rod 3 is 292mm, the distance between the eighth sound hole 15 and the top end of the suona rod 3 is 111mm, the length of the suona rod 3 is 370mm, and the inner diameter of the lower end of the suona rod 3 is 27mm.

[0055] Three, for the super low range.

[0056] The ultra-low range includes 4 keys. None of them are commonly used. The reasons for not being commonly used: first, the volume is too large, not convenient to carry. The normal oboe bag and oboe box cannot accommodate it. Second, the distance between the sound hole 9 is too large, which is the limit of the spread of the fingers. The smaller hands cannot play it. Even if the person with large hands plays it, it is more tiring.

[0057] For comparison, take the D oboe. It weighs about 100 grams. The weight of the large D oboe is more than 500 grams. It will be very tiring to drag it with a finger for a long time.

[0058] The solution proposed by the utility model: reduce the volume, reduce the weight, and reduce the sound position. For detailed comparison of large F and large D.

[0059] Adjustment position and method: the oboe whistle piece 1 and the core 2 are common in the middle and low sound areas. The length of the large D oboe core 2 is 120 mm, and the distance of the improved oboe core 2 inserted into the oboe is only 40 mm.

[0060] Method for solving the problem of sound hole distance: move the sound hole upward. Let the hole position be reduced. This will cause the sound hole to move. Changing the taper will change the pitch. By changing the taper, the sound hole pitch is adjusted. After adjusting the taper, the volume will be smaller. Then expand it evenly according to the taper. Adjust to the standard of round, transparent, and loud sound.

[0061] The result of the improvement: the total length of the core 2 rod is 545 mm. After being divided, the longest is 385 mm, solving the problem of inconvenience in carrying.

[0062] Before improvement, the original size: the total length of the core 2 rod is 580 mm, which is shortened by 35 mm after improvement. Before improvement, the finger control area is 248 mm, and after improvement, the finger control area is 225 mm. After improvement, the sound hole distance is reduced by 23 mm. Even the small players can play the large D oboe.

[0063] Embodiment 6: large F oboe

[0064] Combined with the drawings Figure 9 The improved oboe of this model, the oboe rod 3 is improved as follows: the distance between the first sound hole 8 and the top end of the oboe rod 3 is 105 mm, the distance between the second sound hole 9 and the top end of the oboe rod 3 is 154 mm, the distance between the third sound hole 10 and the top end of the oboe rod 3 is 177 mm, the distance between the fourth sound hole 11 and the top end of the oboe rod 3 is 220 mm, the distance between the fifth sound hole 12 and the top end of the oboe rod 3 is 260 mm, the distance between the sixth sound hole 13 and the top end of the oboe rod 3 is 295 mm, the distance between the seventh sound hole 14 and the top end of the oboe rod 3 is 323 mm, the distance between the eighth sound hole 15 and the top end of the oboe rod 3 is 126 mm, the length of the oboe rod 3 is 416 mm, and the inner diameter of the lower end of the oboe rod 3 is 25.6 mm.

[0065] Example 7: Large D Suona

[0066] In combination with the Figure 10 The improved model of the suona, the suona rod 3 is improved as follows: the distance between the first sound hole 8 and the top end of the suona rod 3 is 32 mm, the distance between the second sound hole 9 and the top end of the suona rod 3 is 86 mm, the distance between the third sound hole 10 and the top end of the suona rod 3 is 112 mm, the distance between the fourth sound hole 11 and the top end of the suona rod 3 is 162 mm, the distance between the fifth sound hole 12 and the top end of the suona rod 3 is 202 mm, the distance between the sixth sound hole 13 and the top end of the suona rod 3 is 225 mm, the distance between the seventh sound hole 14 and the top end of the suona rod 3 is 257 mm, the distance between the eighth sound hole 15 and the top end of the suona rod 3 is 60 mm, the length of the suona rod 3 is 385 mm, and the inner diameter of the lower end of the suona rod 3 is 24.5 mm.

[0067] In this embodiment, a detachable extension tube should also be added to the front end of the suona rod 3, which is inserted into the suona rod 3 by 15 mm, leaving a length of 105 mm after insertion. Although the entire suona rod 3 is longer than that of the general large D suona after the addition of the extension tube, the core 2 used is the general core 2 in this application, which is much shorter than the core 2 used in the general large D suona, so the overall length of the large D suona in this embodiment is still less than that of the traditional general large D suona.

[0068] Through the above improvement scheme, the technical effect of "four large and two small and two unification" is realized, and the specific analysis is as follows:

[0069] Four large: large whistle piece, large spout, large inner chamber, large sound hole

[0070] The increase of the whistle piece can make the volume larger, and it is easier to control and more labor-saving during performance. The size comparison table is as follows Table 1, unit: cm;

[0073] The large spout is reflected on the suona core; the whistle piece is enlarged, and the sound volume generated must be transmitted to the suona through the core. Therefore, the inner diameter of the core must be large enough to transmit the large sound volume generated by the whistle piece to the suona rod; the size comparison table is as follows Table 2, unit: cm;

[0074] Table 2: Size details of traditional core

[0075]

[0076]

[0077] The large inner chamber is the inner diameter of the sorna stem; the inner diameter of the sorna stem, especially the expanded thin part, makes the performance more labor-saving and the transmission of sound more smooth.

[0078] Large sound hole: the large sound hole makes it easier for the performer to operate and slide, and also makes each sound more full.

[0079] Two small:

[0080] The first is the reduction of the key, and each sorna reduces the key to different degrees. The reduction of the key is to reduce the difficulty of sorna performance. In particular, the sorna with large key. The sorna in the bass region and the sorna in the super-bass region do not need to separately practice the performance of large key with great effort.

[0081] The second is to reduce the overall length of the sorna. The sound is brighter, and the size comparison table is shown in Table 3, unit: cm;

[0084] Two unification:

[0085] The traditional sorna is one key corresponding to one whistle piece and one core, and the sizes are different. The higher the sorna, the smaller the whistle piece, and the lower the sorna, the larger the whistle piece. The higher the sorna, the shorter the core, and the lower the sorna, the longer the core. Each sorna is different.

[0086] The sorna of each embodiment of the present application unifies the whistle piece and the core. It saves the time of repairing the whistle piece of the sorna and saves the cost of matching one whistle piece for each sorna. At the same time, it also saves the cost of the core, and condenses into one kind of high-quality universal core.

[0087] The above describes the present application and its embodiments, which are not limited. The embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the present application, without creative design, similar structure and embodiments similar to the technical solution can be designed, which should belong to the protection scope of the present application.
