Description

elbow hole flute

technical field

The utility model relates to a hole flute, in particular to a bent-pipe hole flute capable of playing bass and playing with less effort.

Background technique

Dongxiao is an excellent wind instrument in my country. Please refer to Figure 1, which is a schematic diagram of the appearance of the existing Dongxiao. Sectional and hollow. There is a mouthpiece 13 on the top, which is called a mountain pass, from which the air is blown to make a sound. In the middle part of the bamboo tube 11, a plurality of (usually five) sound holes 14 are opened on the front side, and a sound hole (not shown) is arranged on the back side to change the pitch of the sound. The two round holes on the back of the lower end of the tube are sound holes (not shown) for tuning. There are also two auxiliary sound holes (not shown) below the sound hole to beautify the tone and increase the volume.

The high and low pitch of the flute is absolutely related to the length of the flute, which is the multiple of the wavelength and half wavelength of the sound of the flute. If the hole flute does not have a sound hole, that is, the sound hole 14 is all covered by the flute blower's fingers, then the distance from the mouthpiece to the end of the flute is exactly the sound wave half-wavelength length of the flute tube sound (lowest tone). In order to make the flute emit lower-pitched sound waves, the length of the flute is often designed to be particularly long. For the flute 20 shown in Figure 2, its bamboo tube 21 is longer than the bamboo tube 11 in Figure 1, so the sound hole 22 at the end of the flute 20 It will also be far away from the flute player's body, so that the flute player must stretch his arms to play, making it more laborious to play. In addition, those with shorter stature also have shorter arms, and may even be unable to play. Therefore, this type of extended bass hole flute 20 is difficult to be called practical.

In view of the above-mentioned shortcomings, the creator felt that it was not perfect, so he exhausted his mind to study and overcome it. With his accumulated experience in this industry for many years, he developed a kind of hole flute, which can make the utility model reach the level of playing bass and playing bass. Less strenuous effect when playing.

Contents of the invention

Therefore, the main purpose of the present utility model is to design a kind of bent pipe flute, which can achieve the effect of playing bass and playing with less effort.

For reaching above-mentioned purpose, the realization technology of the present utility model is as follows:

A bent-pipe flute, comprising: a mouthpiece; a hollow pipe body with several sound holes and bamboo joints arranged on its surface; and a hollow bent pipe connected between the mouthpiece and the hollow pipe body. , to increase the length of the airflow path from the mouthpiece to the bottom of the hollow tube body.

In order to make the above and other purposes, features and functions of the present invention more obvious and understandable, the present invention will be described in detail by means of the following specific embodiments and accompanying drawings.

Detailed ways

Since the distance from the mouth of the hole flute to the end of the flute is the half-wavelength length of the sound wave of the sound of the flute (lowest tone), if the length of the airflow path blown by the player from the mouth of the hole flute to the air flow path in the hole flute can be increased, the sound of a lower pitch can be made from the flute. sound waves. The utility model enables the flute to emit lower-pitched sound waves without increasing the length of the flute.

Please refer to Fig. 3 and Fig. 4, which are respectively the enlarged view and the appearance diagram of the elbow flute of the present utility model, as shown in the figure: the elbow flute 30 of the utility model is mainly composed of a mouthpiece 33, a hollow pipe body 31 and A hollow bent tube 35 is formed. Mouthpiece 33 provides the player's mouth to blow air. The hollow tube body 31 is made by hollowing out the inside of bamboo, and its surface is equipped with several sound holes 34 and several bamboo joints 32. The number of sound holes 34 can be 5 to 6, which can be customized according to different needs. The hollow bent tube 35 is connected between the mouthpiece 33 and the hollow body 31, which can be a spiral hollow tube, a V-shaped hollow tube or a U-shaped hollow tube, etc., to increase the mouthpiece 33 to The airflow path length at the bottom of the hollow pipe body 31.

When the player is playing the curved pipe flute 30 of the present utility model, if the hollow bent pipe 35 is a spiral hollow pipe, the lengths of the existing flute and the curved pipe flute 30 of the present utility model will be the same (assuming the other The length of the mouthpiece and the hollow body are the same). Generally speaking, if the length of the flute is the same, the degree of the bass played will be the same, but the curved pipe flute 30 of the present invention will increase the mouthpiece 33 to the hollow body 31 due to the design of the spiral hollow pipe. The length of the airflow path at the bottom, so the airflow path is longer and can play a lower sound wave. Also because of the design of the spiral hollow tube, the length of the curved pipe flute 30 of the present utility model will not increase, so the sound hole 34 at the end of the hollow tube body 31 will not be too far away from the player, and the player's arm will not be too far away. It does not need to be straightened to play, and it is less strenuous to play.

If the hollow bent pipe 35 is a V-shaped hollow pipe or a U-shaped hollow pipe, the length of the curved pipe flute 30 of the utility model will be slightly longer than that of the existing flute, but the length of the airflow path can be increased several times. Due to the increased length of the curved pipe hole 30, the sound hole 34 at the end of the hollow pipe body 31 will not be too far away from the player, and the player only needs to extend his arm a little to play the bass, and it is not laborious to play.

To sum up, the utility model is indeed feasible, and improves various shortcomings of the prior art. It is a highly practical model that is innovative and meets the needs of the industry, and has novelty and progress, and fully meets the requirements of the new patent. Statutory requirements, according to the law to file a new patent application.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the patent scope of the present utility model; all other equivalent changes or modifications completed without departing from the spirit disclosed by the present utility model shall be fall within the scope of the following claims.
