Description

Technical Field

[0001] The utility model relates to the technical field of Hulusi, in particular to an eight-hole Hulusi with a wide range of sound. Background Art

[0002] The Hulusi is a traditional folk musical instrument with a unique and simple timbre, a plain and delicate appearance, and is easy to learn. It is loved by many music lovers. The shape and structure of the Hulusi are unique. It is made of a complete natural gourd, three bamboo tubes and three metal reeds. The whole gourd is made of three bamboo tubes of different thicknesses inserted into the lower part of the gourd. Each bamboo tube inserted into the gourd is inlaid with a reed. The middle bamboo tube is the thickest and has several sound holes on it. It is called the main tube, and the two sides are auxiliary tubes. The mouthpiece and the angle of the tongue reed of the Hulusi have a very important influence on the timbre.

[0003] The seven-hole wide-range Hulusi currently in use has a range of 3 4 5 6 7 from the lowest note to the highest note 1 2 3 45 6 7 , by adding a sleeve and using cross-fingering, etc., the range of the sound is expanded, which is wider than that of the traditional Hulusi, but it has one less note than the nine-hole Hulusi. It can only play traditional Hulusi music and a few songs with a narrow range. Due to the limitation of the range, in most cases it can only be played as a solo instrument and it is difficult to use it for song accompaniment; and the Hulusi currently used, after playing for a long time, saliva will gradually enter the inside of the gourd. If it is not handled in time, it will cause mold inside and breed bacteria, affecting the health of the user. The common treatment method is to turn the used Hulusi upside down to make saliva flow out of the mouthpiece. Because the natural gourd is easy to penetrate saliva, and the air flow inside the gourd is small, it is difficult to dry quickly by just letting the saliva flow out. Utility Model Content

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0017] The utility model provides a cucurbit flute with eight sound holes and wide range, comprising a cucurbit body 1, a mouthpiece 2, a main sound pipe 3, a left auxiliary pipe 4 and a right auxiliary pipe 5, wherein the front side of the main sound pipe 3 is provided with a first sound hole 8, a second sound hole, a third sound hole, a fourth sound hole, a fifth sound hole, a sixth sound hole and a seventh sound hole in sequence from bottom to top, the mouthpiece 2 is fixedly connected to the top of the cucurbit body 1, a plug-in hole is provided at the bottom of the cucurbit body 1, a limiting sleeve 6 is installed on the plug-in hole, a base 7 is detachably installed on the limiting sleeve 6, the main sound pipe 3, the left auxiliary pipe 4 and the right auxiliary pipe 5 are all installed on the base 7, and an eighth sound hole 9 is provided on the main sound pipe 3 and is located obliquely below the first sound hole 8.

[0018] like Figure 1 and 2As shown, the existing seven-hole wide-range Hulusi bass 3 (D), also known as the harmonic hole, is on the back of the main sound pipe 3. When in use, the sound hole of the bass 3 does not need to be pressed by fingers. The utility model is based on the existing seven-hole wide-range Hulusi, and an eighth sound hole 9 is opened obliquely below the first sound hole 8 on the front of the main sound pipe 3 (because the little finger is shorter, it is convenient for the little finger to press), and a 1.5 cm long sleeve is installed on the eighth sound hole 9, so as to increase the air flow resistance in the main sound pipe 3 and the channel length of the eighth sound hole 9, and adjust the pitch of the bass 3. The distance between the center of the eighth sound hole 9 and the center of the first sound hole 8 is 2.7 cm, and the distance between the center of the eighth sound hole 9 and the harmonic hole is 8.5 cm. In order to avoid the newly added eighth sound hole 9 affecting the overall pitch, the B-tuned Hulusi is adjusted to For example, the length of the main tone tube 3 is increased. For example, the length of the commonly used Hulusi main tone tube 3 is 35 cm. In this embodiment, the length of the main tone tube 3 is increased to 38 cm. The pitch of the tone is related to the frequency of vibration of the sound-emitting body. The shorter the main tone tube 3 is, the faster the sound-emitting body vibrates, the higher the frequency is, and the higher the tone is. On the contrary, the longer the main tone tube 3 is, the slower the sound-emitting body vibrates, the lower the frequency is, and the lower the tone is. The farther the distance between the sound hole and the reed is, the lower the vibration frequency is, and the lower the tone is. Therefore, when using the Hulusi with the newly added eighth tone hole 9, the eighth tone hole 9 is pressed by the little finger. Based on the international general tuning standard 440HZ, it is measured that the tone emitted by the overtone hole is bass 2, and when the eighth tone hole 9 is not pressed, the tone emitted is bass 3. The tone examples from the lowest tone to the highest tone in the range are 2 3 4 5 6 7 1 2 3 4 5 6 7 Compared with the existing seven-hole wide-range Hulusi, a bass 2 is added; the inventor's performance proves that it can play more folk music, traditional famous songs and popular music, and can better express the thoughts and feelings of the performer, and the performance method is scientific and convenient; the limiting sleeve 6 is fixed to the plug-in hole at the bottom of the gourd body 1 by adhesive, and the base 7 is detachably installed in the limiting sleeve 6. For the convenience of cleaning and drying, the base 7 can be disassembled as a whole, and the cavity of the gourd body 1 can be cleaned or disinfected by washing, scrubbing, etc., and then the residual liquid in the gourd body 1 is removed by natural wind or tools such as fans, thereby improving the drying speed of the inner cavity of the gourd body 1 and preventing saliva from breeding bacteria and affecting the health of the user.
