Description

Technical Field

[0001] This invention relates to the field of wind musical instruments, and in particular to a type of gourd flute that is easy to produce high notes. Background Technology

[0002] The traditional hulusi consists of a mouthpiece, a gourd, a main pipe, and two auxiliary pipes. The traditional hulusi main pipe has seven holes, resulting in a narrow range. Improved versions have eight or nine holes, but still cannot produce more notes, limiting the hulusi's musical expressiveness. When a player needs to play melodies in different tones, they can only do so by changing the hulusi to a different tone, which affects the playing effect.

[0003] There is an existing Chinese invention patent entitled "A Wide-Range Hulusi for Easy Playing" (CN201720889644.X), which designs the tone holes as twelve holes and controls the opening and closing of the tone holes through multiple tone plugs, thereby expanding the tone range of the hulusi and solving the operation problem well, and greatly improving the performance effect and expressiveness.

[0004] The applicant discovered that the wider range of the above-mentioned design made it difficult to produce the high note "re," rendering the tone hole practically useless. Furthermore, it severely hampered the playing of middle notes. Therefore, there is an urgent need for a new type of hulusi that can easily produce high notes such as "re" to ensure successful playing. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a hulusi (a type of Chinese flute) that facilitates the production of high notes, making it easier to play high notes such as C. To achieve the above objective, this invention adopts the following technical solution:

[0007] (II) Technical Solution

[0008] A type of hulusi (a type of Chinese flute) that facilitates the production of high notes includes a sound tube and a reed. The reed has a tongue and is fixed to the sound tube. It also includes a pressure plate and a pressure rod. One end of the reed near the root of the tongue is suspended and connected to the top of one side of the pressure plate. The pressure rod is movably mounted on the sound tube, and when the pressure rod is in motion, one end of it can contact the bottom of the other side of the pressure plate.

[0009] Furthermore, the pressing platform includes a pressing platform body and an ejector pin platform. The top of one side of the pressing platform body is connected to the spring sheet, and the bottom extends outward to form a fine-tuning top plate. A rotating shaft is fixedly provided at the bottom of the other side of the pressing platform body. The middle part of the ejector pin platform is rotatably connected to the rotating shaft. One end of the ejector pin platform is provided with an ejector pin, and the other end is provided with a fine-tuning screw. The threaded end of the fine-tuning screw rests on the bottom of the fine-tuning top plate.

[0010] Furthermore, the ejector pin passes through the ejector pin stage via a thread.

[0011] Furthermore, the rotating shaft is provided with a torsion spring, the free end of which is pressed against the bottom of the ejector pin platform from below.

[0012] Furthermore, the top of the pressure table body is provided with at least three pressure blocks, which are divided into upper and lower layers and staggered from each other. A retaining groove is formed between the two layers of pressure blocks, and the spring is embedded in the retaining groove.

[0013] Furthermore, the sound tube has a fine-tuning hole at the corresponding position below the fine-tuning screw.

[0014] Furthermore, it also includes a transmission rod. Both the pressure rod and the transmission rod are L-shaped, and their middle parts are rotatably fixed inside the sound tube by a fixed shaft. One end of the pressure rod is in contact with the pressure table, and the other end is connected to one end of the transmission rod by a wire. The other end of the transmission rod is connected to another wire, which passes through a wire hole on the wall of the sound tube and is connected to an external operating rod.

[0015] Furthermore, the operating lever is a sound stopper.

[0016] Furthermore, the transmission rod is inclined when the sound hole is closed, and the end of it connected to the operating rod is lower than the fixed shaft above it.

[0017] Furthermore, the operating lever is equipped with a limiting block that keeps its maximum range of motion constant.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention has significant advantages and beneficial effects, specifically:

[0020] 1. The reed root is suspended and connected to a pressure plate. The pressure rod is pressed down on the bottom of the pressure plate, causing the pressure plate to swing around the connection between the reed and the sound tube. The suspended end of the reed is deformed under the action of the pressure plate, causing the reed tongue to curl up, making it easier to vibrate, thus easily producing middle C and high notes such as C and D.

[0021] 2. Equipped with a torsion spring and a fine-tuning screw, it can adjust and fix the contact position between the pressure table and the pressure rod, ensuring that the pressure rod can contact the pressure table, thereby achieving the lifting of the spring tongue;

[0022] 3. The thimble can also be adjusted in height, further increasing adjustability and ensuring successful playing;

[0023] 4. By setting up a silk thread and transmission rod, the function of controlling the pressure lever using the tone stop's operating handle is realized. The player opens the tone hole to prepare to play the high note "re," and the reed simultaneously lifts, making playing more natural. No other operation is required, and it is easy to learn. It can be widely promoted.

[0024] 5. A limit block is provided on one side of the control handle. When playing, the control handle is rotated to contact the limit block each time to ensure the consistency of the rotation angle of the control handle. This ensures that the rotation angle of the lever remains unchanged each time, and the angle of the reed tongue remains unchanged, thus ensuring the stability of playing. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Please see Figure 1 As shown, a type of hulusi (a type of gourd flute) that facilitates the production of high notes includes a sound tube 1 and a reed 2. The reed 2 has a tongue 21 and is fixed to the sound tube 1 for vibration and sound production. Specifically, it also includes a pressure platform 3 and a pressure rod 4. One end of the reed 2 near the root of the tongue 21 is suspended and connected to the top of one side of the pressure platform 3. The pressure rod 4 is movably mounted on the sound tube 1. Figure 2 When the pressure rod 4 moves, one end of it contacts the bottom of the other side of the pressure platform 3, causing the pressure platform 3 to swing around the connection between the reed 2 and the sound tube 1. The suspended end of the reed 2 deforms under the action of the pressure platform 3, causing the reed tongue 21 to lift up, making it easier to vibrate, thus easily blowing out high notes such as re.

[0041] To avoid affecting the vibration of the reed tongue 21, the connection between the pressure table 3 and the reed 2 should not extend beyond the root of the reed tongue 21.

[0042] Considering that the inner diameter of the sound tube 1 is often less than 15mm, it is difficult to determine the installation position between the pressure table 3 and the pressure rod 4. Therefore, the pressure table 3 needs to have an adjustable structure, the specific structure of which is described in Example 1.

[0043] Example 1

[0044] like Figure 3-6The pressure table 3 includes a pressure table body 31 and a pin table 32. The top of one side of the pressure table body 31 is connected to the spring 2, and the bottom extends outward to form a fine-adjustment top plate 312. A rotating shaft 33 is fixedly provided at the bottom of the other side of the pressure table body 31 (the rotating shaft 33 and the pressure table body 31 do not rotate relative to each other). The middle part of the pin table 32 is rotatably connected to the rotating shaft 33. One end of the pin table 32 is provided with a pin 35, and the other end is provided with a fine-adjustment screw 36. The threaded end of the fine-adjustment screw 36 rests on the bottom of the fine-adjustment top plate 312.

[0045] During assembly, first fix the reed 2 onto the pressure plate body 31, then place the pressure plate 3 inside the sound tube 1, and then use glue to fix the reed 2 onto the sound tube 1; confirm by testing whether the pressure rod 4 can contact the ejector pin 35 when it moves and whether the pressure plate 3 can smoothly produce a high note (re) when it swings. If not, proceed as follows. Figure 3 The angle of the ejector plate 32 is adjusted by fine-tuning screw 36 until the above purpose is achieved.

[0046] It is worth mentioning that the ejector pin 35 is also a screw, which passes through the ejector pin platform 32 through a thread. By turning the ejector pin 35, its height can be changed, further increasing adjustability and expanding the scope of application.

[0047] It should be noted that, in order to ensure that the angle of the ejector plate 32 remains unchanged and to prevent the fine-tuning screw 36 from loosening, a torsion spring 34 is provided on the rotating shaft 33. The free end of the torsion spring 34 presses against the bottom of the ejector plate 32 from below, so that the fine-tuning screw 36 is tightly pressed against the fine-tuning top plate 312 to prevent it from loosening.

[0048] It is understandable that, for ease of installation and replacement, the top of the pressure table body 31 is provided with at least three pressure blocks 313. The pressure blocks 313 are divided into upper and lower layers and are staggered with each other. A retaining groove 311 is formed between the two layers of pressure blocks 313, and the spring 2 is embedded in the retaining groove 311. When disassembling and assembling, only the spring 2 needs to be pulled out, which is quick and convenient and does not affect the vibration of the spring tongue 21.

[0049] For easy adjustment, the sound tube 1 has a fine adjustment hole 12 at the corresponding position below the pin 35 and the fine adjustment screw 36. A screwdriver can be inserted into the sound tube 1 through the fine adjustment hole 12 for adjustment.

[0050] To facilitate operation and avoid the need for additional operations to control the pressure lever 4 during playing, the existing tone block frame on the gourd can be used to operate the pressure lever 4, making the playing more natural, as described in Example 2.

[0051] Example 2

[0052] This embodiment also includes a transmission rod 5. Both the pressure rod 4 and the transmission rod 5 are L-shaped, and their middle parts are rotatably fixed inside the sound tube 1 by a fixed shaft 6. One end of the pressure rod 4 is in contact with the pressure table 3, and the other end is connected to one end of the transmission rod 5 by a wire 7. The other end of the transmission rod 5 is connected to another wire 7, which passes through the wire hole 11 on the wall of the sound tube 1 and is connected to the sound plug on the external sound plug frame.

[0053] When the player needs to play a high C, they press the lever connected to the corresponding stop, causing the stop to rise. At this time, as... Figure 2 As shown, the stop pulls up one end of the transmission rod 5 through the thread 7, and the transmission rod 5 rotates around the fixed shaft 6 on it, so that the other end of the transmission rod 5 moves away from the pressure rod 4. Since this end of the transmission rod 5 and one end of the pressure rod 4 are connected by the thread 7, the transmission rod 5 will synchronously drive the pressure rod 4 to rotate, so that the other end of the pressure rod 4 is pressed down. When the other end of the pressure rod 4 is pressed down to contact the pin 35, it will cause it to swing, lifting the reed tongue 21, thus easily blowing out the high note re.

[0054] In this embodiment, the control handle of the sound stop drives the pressure rod 4 to rotate, thereby swinging the pressure platform 3. This achieves natural control of the pressure platform 3, requiring no other operations. It can be played like any other hulusi, making it easy to learn. It should be noted that, to ensure the consistency of the reed tongue 21's tilt angle each time and to ensure playing stability, a limit block is provided on the outer wall of the sound tube 1 on one side of the control handle. During playing, the control handle is rotated until it contacts the limit block each time, ensuring the consistency of the control handle's rotation angle. This keeps the rotation angle of the pressure rod 4 constant each time, thus keeping the tilt angle of the reed tongue 21 constant and ensuring playing stability.

[0055] It is understandable that, such as Figure 1 The transmission rod 5 is inclined when the sound hole is closed, that is, the end of it connected to the sound plug is lower than the fixed shaft 6 above it, so that once one end of the transmission rod 5 is pulled up by the silk thread 7, it can simultaneously drive the other end away from the pressure table 3, ensuring the flexibility of operation.

[0056] To avoid affecting playing, all holes must be sealed, such as... Figure 7 As shown, rubber rings 8 are provided around the spring 2, and the pressure plate 3 is covered by a rubber membrane 9. The fine adjustment hole 12 is tightly plugged by a rubber stopper 10. The thread hole 11 is also tightly plugged by a rubber stopper, but the thread 7 needs to pass through the center of the rubber stopper at the thread hole 11 to ensure that it can be pulled smoothly.

[0057] The core of this invention lies in adjusting the tilt angle of the reed tongue and the reed plate, so that the player can easily play middle C and high notes such as C and D, without affecting the playing of other notes.

[0058] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
