Abstract
Description
Technical Field
[0001] This utility model relates to the field of musical instrument technology, specifically a novel Maodunchaoer. Background Technology
[0002] The Maodun Chaoer is a Mongolian edge-mounted aerophone, also known as Chaoer or Hujia in folk tradition. It is popular in the Inner Mongolia Autonomous Region and the Altay region of Ili Kazakh Autonomous Prefecture in Xinjiang Uygur Autonomous Region. During the Qin and Han Dynasties, our ancestors invented the primitive Hujia, which was a wind instrument made by rolling reed leaves into a double reed shape or a conical tube shape, with the end flattened into a reed. The reed and tube were integrated into one. With the development of society, various forms of Hujia appeared in history. The first was changed from a reed leaf tube to a reed stalk tube. Its shape is similar to the Uygur double-reed single-tube aerophone Balaman. The upper end of the reed tube was flattened into a double reed shape. The tube body and reed were still integrated. The difference is that there are no finger holes on the tube body.
[0003] Existing Maodunchaor instruments require the player to hold and control them with their hands during playing. Because the Maodunchaor's body is similar to a flute, this hand-holding posture easily leads to premature fatigue and muscle cramps in the player's hands. Furthermore, the top of the Maodunchaor needs to press against the player's teeth, and the wooden instrument can easily leave wood shavings in the player's teeth, also causing premature damage to the top of the instrument. Therefore, we have provided a new type of Maodunchaor to solve these problems. Utility Model Content
[0004] 1) Technical problems to be solved
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of Maodunchaoer.
[0006] (ii) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: A novel Mouton Choller tube includes a tube body. Four tuning holes are provided at the bottom front side of the tube body. A replaceable contact nozzle is provided on the outer wall of the top of the tube body. Three locking blocks are arrayed on the outer wall of the bottom end of the replaceable contact nozzle. A limiting frame is fixedly connected to the outer wall of the tube body near the locking blocks. A protective ring is provided on the outer wall of the bottom end of the tube body. An auxiliary mechanism is provided on the outer wall of the tube body near the tuning holes. The auxiliary mechanism includes a left-hand auxiliary block and a right-hand auxiliary block. The left-hand auxiliary block is composed of contact block A. A limiting ring A is fixedly connected to the top of contact block A, and a limiting ring B is fixedly connected to the bottom end of contact block A. A placement groove A is provided on the front side wall of contact block A between the limiting ring A and the limiting ring B. The right-hand auxiliary block is composed of contact block B. A limiting ring C is fixedly connected to the center of the outer wall of contact block B on the outer surface of the tube body. A limiting ring D is fixedly connected to the bottom of the outer wall of contact block B on the outer surface of the limiting ring C. Placement grooves B are provided on both the upper and lower sides of the front side wall of contact block B near the limiting ring C.
[0008] Furthermore, the limiting ring B is positioned between the two tuning holes at the top of the tube body, and the limiting ring C is positioned between the two tuning holes at the bottom of the tube body.
[0009] Furthermore, slots are provided on both the inner and outer walls of the top of the tube body, allowing the inner wall of the replaceable contact nozzle to engage with the slots. The limiting frame is arranged in an "L" shape, and a sleeve groove that engages with the protective ring is provided on the outer wall of the bottom of the tube body.
[0010] Furthermore, the left-hand auxiliary block is positioned above the right-hand auxiliary block, the inner wall of contact block A engages with the outer wall of the tube body, the limiting ring A and the limiting ring B are sleeved on the outside of the tube body, and the placement groove A is set at an inclined angle.
[0011] Furthermore, the inner wall of the contact block B engages with the outer wall of the tube body, and the limiting ring D is positioned below the tuning hole.
[0012] Furthermore, a limiting band B is fitted between the left-hand auxiliary block and the right-hand auxiliary block on the outer wall of the tube body, a limiting band A is fitted above the left-hand auxiliary block on the outer wall of the tube body, and a limiting band C is fitted below the right-hand auxiliary block on the outer wall of the tube body.
[0013] (iii) Beneficial effects:
[0014] Compared with existing technologies, this new type of Maodun tidal bore has the following beneficial effects:
[0015] I. This utility model involves placing the left index and middle fingers on the upper and lower sides of the limiting ring B, respectively, with the placement groove A guiding and limiting the left index finger. Simultaneously, the right index and middle fingers hold the tube body and place it below the limiting ring C, while the right thumb is placed in the placement groove B on the limiting ring C under the guidance of the limiting ring C. While holding the tube body, the contact blocks A and B support the left and right palms. This solves the problem that the existing Maodunchaor tube body is similar to a flute and the holding posture of the Maodunchaor easily causes premature fatigue of the performer's hand muscles. It has the advantage of conforming to the performer's hand.
[0016] Second, this utility model uses a rotating replaceable contact nozzle to cause the locking block to disengage from the limiting frame. At this time, the replaceable contact nozzle can be removed from the tube body, thereby realizing replacement. This solves the problem that the top of the existing Maodunchaur needs to be pressed against the player's teeth, and the wooden Maodunchaur is prone to wood chips remaining in the player's teeth, causing premature damage to the top of the instrument. It has the advantage of a replaceable nozzle. Attached Figure Description
