The present invention relates to a pad structure that can improve the tone of a wind instrument while maintaining its shape even after long-term use.
In general, sound transmitted through wind instrument utilizes the vibration of air.
A number of cap holders are formed inside the wind instrument, a pad is attached to the inside of the cap holders, and by vibrating the pad, the wind instrument resonates and produces sound.
As mentioned above, music created through sound using the transmission of air is the art of sound, musical sounds and all sounds originate from the vibration of air, and the wind instrument is regulator that controls the flow of air and are tools that change the flow of air into musical sounds using effect of vibration.
In other words, performance music also utilizes the vibration phenomenon in the air, and performance is a physical phenomenon in which the vibration phenomenon using a musical instrument is heard through the auditory organ via the medium called air.
As mentioned above, the source of musical sound and performance is the vibration that is changed into sound and expressed through performance, the technology to control the vibration is the core principle of controlling musical tools and musical instruments.
Playing a musical instrument is changing vibrations into artistic sounds, expressing these vibrations as artistic sounds, and expressing emotions. Sound when strengthen the vibrations, results in better resonance, and using the resonance artistically is a great performance.
In order to improve the quality of live performance music in an analog state, it is essentially important to improve the performance of the instrument itself. For this reason, professional musicians prefer and choose to use expensive, famous instruments with good sound quality at concerts. A good instrument such as this is called a famous instrument. The good instrument refers to an instrument with good sound quality, good timbre, rich volume, and good aftertone and resonance. Furthermore, an instrument with good resonance is an instrument with regular vibration periodicity. In other words, an instrument with regular vibration periodicity and good vibration periodicity is referred to as a famous instrument.
As shown in
If the shape of the pad 2 or key 3 is deformed for various reasons, a space S is created between the upper main part 1b and the pad 2. If the vibration sound leaks through the space S, an incorrect sound is generated.
To produce the correct sound, the space(S) must be removed.
The conventional pad 2 structure made of leather and wool filling inevitably hardens over time, and it is not easy to remove the space S caused by this hardening phenomenon.
Accordingly, there is a need for research on a pad structure that prevents the space S from being created between the upper main part 1b and the pad 2 due to not being hardened for a long time.

As described above, the space S between the tone hole and the pad of the wind instrument prevents a sound from being produced correctly. The reason why the space S is formed is that a material forming the pad hardens over time. Therefore, the present invention proposes to solve the above problem by using the pad with a material that does not harden.
Referring to
Typically, a keypad (pad) for the tone hole has one side attached to the upper main part 1b of the tone hole tube 1 and the other side attached to the inner surface of the key 3 that detachably operates the pad 2.
One end of an arm 4 is attached to an outside of the key 3, the other end of the arm 4 is connected to a key rod 5, and a key button 6 is arranged.
As already explained in the background art, the space S is created between the upper main part 1b and the pad 2, the pad 2 is attached (or detached) to the upper main part 1b of the tone hole tube 1 and closes the upper main part 1b, so that the vibration sound leaks out through the space S, and thus the original sound is not generated.
The pad 2 includes a contact leather part 2a that contacts with the upper main part 1b of the tone hole tube 1, a filling material part 2b in which a plurality of thin papers are overlapped and arranged on the inner side of the contact leather part 2a, and an inner leather part 2c in which the edge of the contact leather part 2a is adhered to the inner self-edge of the filling material part 2b, and the keypad structure A for the tone hole of all wood wind instruments is such that an empty inner space S1 is formed between the inner leather part 2c of the pad 2 and the inner surface 3a of the key 3.
The pad 2 includes a leather contact leather part 2a that contacts with the upper main part 1b of the tone hole tube 1, a filling material part 2b in which a plurality of thin papers are overlapped and arranged on the inner side of the contact leather part 2a, and an inner leather part 2c in which the edge of the contact leather part 2a is adhered to the inner self-edge of the filling material part 2b.
Looking at the structure of the pad 2 in more detail, the filling material part 2b of the pad 2 is composed of wool, synthetic fiber fabric, or thin paper aggregate, and thin paper 2d is attached to the upper and lower surfaces of the filling material part 2b, and the contact leather part 2a and the inner leather part 2c are adhered to the upper and lower surfaces of the filling material part 2b, and a fixing plate 2 penetrates and fixes the contact leather part 2a, the filling material part 2b, and the paper 2d in the middle of the pad 2.
The contact leather part 2a and the inner leather part 2c, as well as the filling part 2b, are all made of materials vulnerable to moisture. However, the pad 2 is always exposed to moisture due to the moisture contained in the breath of the player when the wind instrument is played. Since the pad 2 must always be exposed to moisture, but are made of materials vulnerable to moisture, there is a problem that the pad 2 is harden easily.
An embodiment of the present invention that improves the above problems will be described with reference to
According to an embodiment of the present invention, the pad adhesive to the upper main part of a tone hole tube to open and close the tone hole of the wind instrument may be configured to include a circular silicone pad 501 that closes to the upper main part; a fixing pad 505 for fixing the circular silicone pad to the inner surface of a key; and at least one adhesive layer 502, 504 for bonding the fixing pad and the circular silicone pad.
As described above, in order to eliminate the space S between the upper main part and the pad, a material that is not hardened but has a certain degree of elasticity is required. For this purpose, in an embodiment of the present invention, silicone is proposed as such a material. That is, the circular silicone pad 501 can seal the tone hole by directly or indirectly contacting the upper main part, and the sealing effect can be sufficiently expected due to the elasticity of the silicone material.
In particular, the thickness of the silicone pad 501 is about 2 to 3 mm, and the slope of the curve can be formed so that it becomes thinner from the center to the edge. This is to effectively seal the tone hole. If the silicone pad 501 has a flat disc shape, the tone hole cannot be effectively blocked, and the inside may float.
In particular, the hardness of the silicone material of the silicone pad 501 according to a preferred embodiment of the present invention is 20 to 40 in Shore hardness (Shore A). If shore hardness is less than 20, a feeling of inconsistency in playing is formed due to a sloppy feeling when the player presses the key. If shore hardness is more than 40, the silicon pad 501 is too hard and is not suitable for blocking the tone hole.
However, there is a problem that silicone material is difficult to effectively fix to the inner side of the key. This is because, when fixing to the inner side of the key, shellac or glue gun is usually used, but silicone material is difficult to fix with shellac or glue gun.
In order to enable fixation using shellac or glue, the pad 2 according to an embodiment of the present invention is proposed to further include a fixing pad 505. That is, the fixing pad 505 is a configuration for fixing the silicone pad 501 to the inner surface of the key.
The fixed pad 505 according to an embodiment of the present invention is proposed to be formed of a cork material. This is because the cork material is easy to combine with the silicone pad 501 through an adhesive layer (which may be formed by applying an adhesive or may include a thin layer on which an adhesive is applied), and at the same time, it is easy to fix the cork material to the inner side of the key using shellac or glue gun.
In addition, the elasticity of the cork material itself has the advantage of being able to assist the elasticity of the silicone material.
Furthermore, the cork material is quite effective in the structure of the pad 2 according to an embodiment of the present invention because the cork material can provide appropriate elasticity for easy bonding with the reflector 503 described below.
In general, the structure of the pad 2 is very important in controlling the tone of the wind instrument because the structure of the pad 2 is directly related to the resonance when covering the tone hole. Therefore, most players will be difficult to use the pad 2 if the tone of the wind instrument changes, no matter how much durability of the pad 2 made of silicon material improves. Therefore, in order to produce the same tone as the conventional leather-type pad even when using a silicone pad, one embodiment of the present invention proposes to additionally provide a reflector 503 formed of a predetermined material between the fixed pad 505 and the silicone pad 501.
In particular, the material of the reflector 503 according to one embodiment of the present invention is proposed.
In order to effectively fasten between the reflector 503, the silicon pad 501 and the fixed pad 505, one embodiment of the present invention proposes forming a first adhesive layer 502 between the silicon pad 501 and the reflector 503, and forming a second adhesive layer 504 between the reflector 503 and the fixed pad 505.
The pad 2 formed in this manner is resistant to changes in moisture due to the characteristics of own material of the pad 2, does not harden even after long-term use, and can be easily fixed to the inner surface of the key using shellac or glue gun due to the material of the fixed pad 505, so the pad 2 has the advantage of being easy to attach and detach.
The experiment was conducted by comparing the frequencies of the conventional pad, the case where a silicone pad was applied (
