Description

SOUND IMPROVEMENT MATERIAL WITH SHELAC AND LEAD FOR Wind Instrument WHERE THE COATING IS APPLIED {SOUND IMPROVEMENT COATING COMPOSITION COMPRISING SHELLAC AND REED WHEREWITH}

The present invention relates to the use of a shell scheme that can be utilized as a sound quality improving agent and a lead for wind instruments to which it is applied.

In general, wind instruments (wind instrument, woodwind) is a general name for instruments that use air as a vibrating medium for producing sound. In the West, wind instruments are traditionally divided into woodwinds (clarinet, flute and saxophone) and brass (trumpet, trombone, french horn and tuba). In general, the reed is a thin, small piece made of reed, metal, or plastic used in most woodwind instruments, and vibrates according to the flow of air to become a sound source of the instrument.
In particular, saxophone leads are made of reeds, and a single piece of lead is tightened with a mouthpiece and used as an aperture. In other words, the sound of the saxophone is caused by the player biting the mouthpiece and blowing air to vibrate the lid.
The tip of the lead is made thin in order to vibrate. In the case of a reed made of reed, the tip is warped when the tip is dried. Therefore, wind instrument players using reeds should always pay attention to the storage of reeds so that they can be played with accurate notes.
Even if attention is always paid to the storage of the lead, the economic burden caused by the frequent replacement due to the insufficient shelf life cannot be ignored. Accordingly, there is a need for a study on a method of improving the sound of the lead while keeping the lead longer.
In order to extend the life of the lead and improve the sound quality, Korean Patent No. 10-0453252 (name of the invention: a mouthpiece for a saxophone) proposes a method of modifying an existing mouthpiece structure. In other words, the mouthpiece structure of the conventional saxophone tip has been proposed to change the angle at which the lead is fixed and to form a recess of a predetermined depth to maintain the opening interval continuously.
However, in the case of such a prior document, it is not a structure for improving the lead itself but for maintaining the opening interval in accordance with the distortion of the lead. Therefore, there is a limitation that the sound quality of the existing lead can be maintained for a long time and the sound quality cannot be improved to exceed the sound quality of the existing lead.
Korean Patent Laid-Open Publication No. 10-2017-0042002 proposes a method of adjusting the tightening of the lid and the mouthpiece to disclose a method of improving sound quality. However, these prior documents likewise propose a sound quality improvement method through the structural change of the mouthpiece, not the sound quality improvement effect of the lead itself, there is a limit.
Accordingly, while using the mouthpiece structure of the existing saxophone as it is, there is a need for a study on a combination, a compound that can improve the sound quality of the lead itself.

As mentioned above, thin, small pieces called reeds are used in woodwind instruments such as saxophones and clarinets. These leads vibrate in response to the small air flow generated by the player, and the vibrations produce beautiful sounds.

Depending on the material of the reed, the sound varies. Reeds made of reeds made of reeds made of metal or plastic can produce the best sound, and many players prefer reeds made of reeds.

The tips of these leads are very thin and should be kept moist when playing. Repeated humidification and drying of these tips will cause them to twist and become unusable, so players should always be very careful to keep the tips of the leads dry.

The present invention proposes a sound quality improving agent capable of facilitating storage of leads that are difficult to store as described above while improving durability and improving sound quality.

For this purpose, the sound quality improving agent according to the present invention is proposed to have shellac (shellac) as a main component. Shellac is a natural agent that can withstand temperatures above 100 ℃, so it does not contain chemicals, so it removes mold, blocks house sickness, protects wood, blocks UV rays, and forms harmful gases such as formaldehyde. Harmless to natural ingredients.

[Method for Producing Sound Quality Enhancer for Lead Containing Shellac]

At this time, the shellac may use a powder type edible shellac. Edible shellac refers to shellac in which impurities are removed through several purification processes. The reason for using edible shellac is because the player has to play with his mouth.

In addition, alcohol may be added together with shellac. Alcohol may also be used alcohol alcohol is also harmless to the human body.

When the shellac powder is put into a bottle and mixed with the alcohol, some of the shellac powder subsides and some of the shellac is layered on top of the alcohol. Thus, the solution formed by shellac in alcohol can be transferred to a separate container and used to improve the sound quality of the reed.

[Method of applying sound quality improving agent for lead containing shellac]

Thus, the shellac solution diluted in alcohol may be applied by spraying or applying to the above-mentioned lead. At this time, it may be simply applied once, but according to the following experimental results, it can be seen that the sound quality improvement effect is further improved when applied multiple times. Furthermore, it can also be seen that the effect is better when the lead is immersed in such a solution.

Hereinafter, the experimental results of comparing the surface when the sound quality improver is applied and when not is confirmed.

In each figure, (a) shows the surface when the sound quality improving agent according to the present invention is applied, and (b) shows the surface without the sound quality improving agent applied.

1 and 2, it can be seen that the sound quality improving agent according to the present invention fills the empty space on the surface when the sound quality improving agent is not applied. This filled sound improver improves the resilience of the lead, which results in a clearer sound and better frequency selectivity (frequency quality).

Hereinafter, the frequency analysis result for demonstrating that there exists a sound quality improvement effect by application of a sound quality improving agent is demonstrated. Application of the sound improver was applied in spray form.
