Description

Application of amorphous alloy and/or high-entropy alloy in musical instrument

Technical Field

The invention relates to the technical field of application of amorphous alloy materials, in particular to application of amorphous alloy and/or high-entropy alloy in musical instruments.

Background

Stringed musical instruments (strings) sound in a manner that relies on mechanical force to vibrate tensioned strings, so that the sound volume is limited. String instruments usually use different strings to play different tones, sometimes need to use fingers to press strings to change the string length, thus achieving the purpose of changing the pitch. Stringed musical instruments include pianos, guitars, zithers, lutes, violins, cellos, violoncellos, and the like.

The string of the string instrument is regarded as the sounding part, the choice of its material is very important, the existing string made of metal wire or composite material because under the tension condition for a long time, after a long time under various environments, influence the tone quality easily, the tone quality definition is often unstable, and easy fracture. Also, it is an important tool for generating sound as a reed in a wind instrument. In the process of making sound, the reed bears great vibration, the tone quality of the reed is easily affected, the reed needs to be replaced frequently, and the cost is high.

Therefore, what kind of material is used to prepare the strings and reeds is an urgent technical problem to be solved.

The invention discloses application of amorphous alloy and/or high-entropy alloy in musical instruments. The inventor finds that the amorphous alloy has a low elastic modulus, small damping to sound, large amplitude and stability, so that the tone quality is crisp and the pitch is stable. Similarly, the high-entropy alloy has a lower elastic modulus, smaller damping to sound and larger and stable amplitude, so that the tone quality is clear and crisp, the pitch is stable, and the acoustic performance of the musical instrument can be improved by applying the high-entropy alloy to the musical instrument. It is understood that in one embodiment of the present application, an amorphous alloy is provided for use in a musical instrument. In another embodiment, an amorphous alloy and a high entropy alloy are provided for use in a musical instrument.

Preferably, the titanium-based amorphous alloy has clearer tone quality and more stable treble, mainly because the strength and the elastic modulus of the titanium-based amorphous alloy are moderate. The high-entropy alloy can be, but is not limited to, an as-cast high-entropy alloy, a single-crystal high-entropy alloy, or a fiber sheet high-entropy alloy. The concrete description is as follows:

Further, the stringed musical instrument is selected from a piano, a guitar, a zither, a lute, a violin, a viola or a cello, etc. For stringed instruments, the more important part should be the sound-emitting part, preferably the amorphous alloy and/or the high entropy alloy is used for the strings of the stringed instrument. In one embodiment, the strings of the guitar are made of titanium-based amorphous alloy, so that the guitar has the advantages of high strength and elasticity, low elastic modulus, small sound damping, large and stable amplitude, good anti-relaxation effect, clear and crisp tone quality, high-pitch stability, increased volume and prolonged delay, and the acoustic performance of the musical instrument can be effectively improved. Likewise, the string can also be prepared from copper-based amorphous alloy. The inventor finds that the string made of the titanium-based amorphous alloy has clearer tone quality and more stable high pitch compared with the string made of the copper-based amorphous alloy, mainly because the strength and the elastic modulus of the titanium-based amorphous alloy are moderate. In another embodiment, the string of the Chinese zither is prepared from the as-cast high-entropy alloy, so that the tone quality of the string is crisp and the pitch is stable. The inventor finds that compared with the string made of the cast high-entropy alloy, the string made of the single-crystal high-entropy alloy has clearer tone quality. In another embodiment, the strings of the Chinese zither are prepared by the fiber thin-plate high-entropy alloy and the nickel-based amorphous alloy, so that the Chinese zither has clear and crisp tone quality, stable high pitch, increased volume and prolonged delay, and the acoustic performance of the Chinese zither can be effectively improved.

For wind instruments, there may be, but not limited to, flute, piccolo, clarinet, and oboe. The reed is a generation part of a wind instrument, and the amorphous alloy and/or the high-entropy alloy are used for the reed of the wind instrument. In one embodiment, the reed of the clarinet is made of titanium-based amorphous alloy, so that the clarinet has better strength and elasticity, lower elastic modulus, smaller damping to sound, larger and stable amplitude, and good anti-relaxation effect, especially has crisp tone quality, stable high pitch, increased volume and prolonged delay, and can effectively improve the acoustic performance of the clarinet. Similarly, the reed can also be prepared by copper-based amorphous alloy. The inventor finds that the reed made of the titanium-based amorphous alloy has clearer tone quality and more stable high pitch compared with the reed made of the copper-based amorphous alloy, mainly because the strength and the elastic modulus of the titanium-based amorphous alloy are moderate, and the reed is suitable for the generation part of musical instruments. In another embodiment, the cast-state high-entropy alloy is adopted to prepare the reed of the double-reed pipe, so that the tone quality of the reed is clear and crisp, and the pitch is stable. The inventor finds that the sound quality of the reed made of the single-crystal high-entropy alloy is clearer compared with that of the reed made of the cast high-entropy alloy.
