Description

Technical Field

[0001] This utility model belongs to the field of bamboo flute reed membrane fixing technology, specifically relating to a membrane-stabilizing structure that can maintain the tightness of the flute membrane. Background Technology

[0002] The bamboo flute is a traditional Chinese musical instrument, belonging to the wind instrument category, with a long history and profound cultural heritage. Made of bamboo, it produces a clear, bright tone with rich expressiveness, and is widely used in Chinese folk music, opera, solo performances, and ensembles. Bamboo flutes are typically made from natural bamboo, with common varieties including purple bamboo, bitter bamboo, and white bamboo. The quality of the bamboo and its growing environment directly affect the flute's tone.

[0003] The bamboo flute is made from a single bamboo tube, hollowed out with the nodes removed to form the inner cavity. It has a cylindrical shape and features one blowhole, one membrane hole, six tone holes (for bass flutes such as G and F, there are seven finger holes), two fundamental tone holes, and two auxiliary tone holes. The flute body is made from a single bamboo tube, hollowed out with the nodes removed to form the inner cavity.

[0004] The main purpose of attaching a membrane to the holes of a bamboo flute is to regulate vibration and sound production, making the flute's tone clearer, brighter, and increasing its volume. The membrane is attached to the second hole from the left end of the flute. By adjusting the tightness of the membrane, the flute's timbre and volume can be altered. When installing a reed membrane, the tightness is adjusted, and glue applied around the holes on the flute tube secures it. Reed membranes are typically taken from the stems of bamboo or reeds. Reed membranes produce a clearer sound than bamboo membranes and are therefore more popular.

[0005] The main purpose of attaching the membrane to the membrane hole of a bamboo flute is to regulate vibration and sound production, making the flute's tone crisper, brighter, and increasing volume. When the membrane is attached to the correct tension at the membrane hole, the flute will sound pleasant and melodious. If the membrane is too tight, the sound will be harsh and lack resonance, resulting in a muffled tone and lowering the overall quality of the flute. If the membrane is too loose, the flute will not produce any sound, especially in the high register, producing crackling or hissing noises, and again, an unpleasant tone. Therefore, the tightness of the membrane is crucial to the quality of the flute's tone. The tightness of the membrane is adjusted by the player before playing through a test. However, during the playing of the bamboo flute, the heat from the breath exhaled by the player is absorbed by the flute tube, causing it to expand. This stretches the membrane attached to the tube, resulting in a change in tone. When the player stops playing, the flute tube contracts due to the low ambient temperature, causing the membrane to loosen. This results in a difference in tone from the adjusted tone, affecting the playing of the bamboo flute. Therefore, a membrane-stabilizing structure that can maintain the tightness of the membrane is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a membrane-stabilizing structure that can maintain the tightness of the membrane, thereby solving the above-mentioned technical problems.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] This utility model provides a membrane-stabilizing structure that can maintain the tightness of the flute membrane, including a fastening membrane, an adhesive layer, and a vibration hole. The fastening membrane is glued to the membrane hole on the outer periphery of the flute tube with adhesive.

[0009] The fastening membrane includes an inner pressure layer, a buffer layer, and an outer stabilizing layer. The buffer layer is disposed between the inner pressure layer and the outer stabilizing layer. The adhesive layer is located on the upper and lower sides of the buffer layer, bonding the inner pressure layer and the outer stabilizing layer together to form a three-layer stacked structure.

[0010] The drum vibration hole is created by inserting a knife through the fastening membrane after the fastening membrane is pasted onto the bamboo flute, and it corresponds to the membrane hole.

[0011] Preferably, the overall flatness of the inner pressure layer, buffer layer and outer stabilizing layer is controlled within ±0.5% after being laminated by adhesive layer.

[0012] Preferably, the distance from both sides of the fastening membrane to the drum vibration hole is three-quarters of the distance between the membrane hole and the adjacent flute hole. The fastening membrane is made of a thin film material with high heat resistance and resistance to deformation under tension.

[0013] Preferably, the length of the fastening membrane is more than half the circumference of the bamboo flute.

[0014] The beneficial effects are:

[0015] This invention, through the fastening membrane and the vibration hole, allows the structure to be pasted onto the membrane hole position on the flute tube, and then the reed membrane to be pasted onto the vibration hole position on the fastening membrane. In this way, the inner pressure layer and buffer layer of the fastening membrane can offset the expansion and contraction changes of the flute tube, thereby maintaining the stability of the reed membrane on the outer stable layer. This ensures that the reed membrane is fixed during the flute tube during performance, and also maintains the tone and volume of the bamboo flute under the temperature difference between the natural environment and the air blown by the human body, thus improving the playing effect.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-3 As shown, a membrane-stabilizing structure that can maintain the tightness of the flute membrane includes a fastening membrane 1, an adhesive layer 14, and a drum-vibration hole 2. The fastening membrane 1 is attached to the membrane hole on the outer periphery of the flute tube with adhesive.

[0023] The fastening membrane 1 includes an inner pressure layer 11, a buffer layer 12 and an outer stabilizing layer 13. The buffer layer 12 is disposed between the inner pressure layer 11 and the outer stabilizing layer 13. The adhesive layer 14 is located on the upper and lower sides of the buffer layer 12 to bond the inner pressure layer 11 and the outer stabilizing layer 13 together to form a three-layer stacked structure.

[0024] After the fastening membrane 1 is pasted onto the bamboo flute, the drum vibration hole 2 is opened by a knife through the fastening membrane 1 and corresponds to the membrane hole.

[0025] As an optional implementation, after the inner pressure layer 11, the buffer layer 12 and the outer stabilizing layer 13 are stacked by the adhesive layer 14, the overall flatness is controlled within ±0.5%. This setting allows the fastening membrane 1 to be pasted flat at the position of the bamboo flute membrane hole, thereby improving the installation effect and making it easier to handle the installation of reed membrane.

[0026] See attached document Figure 2 The distance from both sides of the fastening membrane 1 to the drum hole 2 is three-quarters of the distance between the membrane hole and the adjacent flute hole. The fastening membrane 1 is made of a thin film material with strong heat resistance and is not easily deformed by stretching. The fastening membrane 1 can be made of polypropylene material, thereby utilizing the material properties of polypropylene to improve the thermal expansion and contraction buffering effect of the fastening membrane 1.

[0027] Furthermore, the length of the fastening membrane 1 is more than half the circumference of the bamboo flute. This arrangement allows the inner pressure layer 11 to expand and contract synchronously when the fastening membrane 1 is affected by thermal expansion and contraction, while the buffer layer 12 expands or contracts to buffer the expansion and contraction, thereby maintaining the stability of the outer stabilizing layer 13 and keeping the reed membrane in a fixed state.

[0028] Apply glue near the membrane hole of the bamboo flute, and then stick the fastening membrane 1 to the membrane hole position on the bamboo flute. When sticking, maintain the stretch rate of not less than 150% to wrap and seal the membrane hole. Then, open the vibration hole 2 through the knife to make the vibration hole 2 correspond to the size and position of the membrane hole. Then, apply glue to the outermost outer stabilizing layer 13 of the fastening membrane 1 and make the glue cover the vibrating hole 2. Then stick the reed membrane to the vibration hole 2 position on the fastening membrane 1 and adjust the tightness of the reed membrane appropriately.

[0029] By employing the above method, the structure can reduce the cascading effect on the reed membrane when the bamboo flute tube expands and contracts, thereby maintaining the tone and volume of the bamboo flute and improving the playing effect.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
