Description

A strengthen in structure of Guitar and Its producing methode

The present invention relates to a guitar (mainly a classical guitar), and relates to a reinforcing structure of the other neck and a method of manufacturing the same so as to prevent deformation problems such as bending of the neck due to factors such as pulling strings, moisture, temperature changes, etc. will be.

The guitar is composed of a neck coupled to one side of a resonance box and a string arranged from the resonance box over the neck.

However, the neck of the guitar causes torsion and warpage deformation due to string pulling, humidity, and temperature change. This may be due to the fact that the guitar is composed of wood, but the string's continuous pulling load, humidity, and temperature change It is a factor.

Other neck adjusting iron cores are used in part to solve the deformation prevention such as twisting and bending of the neck.

The other neck adjusting iron core is a nut or the like when the neck is bent by pulling the string to operate the adjustment iron core in the direction in which the guitar bends to maintain a horizontal, which can prevent the neck from deformation, such as bending fundamentally It was nothing more than a compensation for deformation.

In order to prevent the bending and twisting of the neck, the structure is strengthened in the longitudinal direction of the neck in the longitudinal direction so that the durability of the neck is strong and the moisture is inserted into the ebony so that the neck is reinforced with less deformation. Not only is the material expensive (black), but also wood, which is sensitive to moisture and temperature changes, which was insufficient to effectively prevent deformation of the neck, such as bending and torsion.

In other words, neck wood and ebony have a considerable difference in moisture absorption rate, which is highly likely to cause torsion and warpage.

In addition, the design (neck-opening utility model publication No. 2000-0018482) is known to constitute a neck using glass fiber reinforced plastic to solve problems such as deformation, splitting, insect eating, etc., such as hygroscopicity, torsion, and bending. This is because the workability is relatively good, but it has not been put to practical use due to the weak rigidity and the high strain rate due to temperature change.

In the present invention, the neck is reinforced by using an alloy having excellent torsion, bending strength and the like without deformation due to moisture and temperature change, and the neck is not only a factor due to the pull load of the string, but also a factor such as temperature change or moisture. It is to effectively prevent the warpage and torsional deformation caused by

Also, from this, the vibration of the resonance box is not transmitted to the neck to obtain a clear and clean sound.

The present invention is provided with a non-ferrous metal reinforcement in the longitudinal direction on the neck (3) of the guitar (1) to effectively prevent the deformation problem that the neck (3) is bent or twisted due to factors such as pulling or moisture of the strings And, it is characterized in that the vibration of the resonance box (2) is not transmitted to the neck (3) to produce a guitar (1) of a clear and clean sound.

The neck 3 of the guitar 1 is coupled to one side of the resonance box 2 as is known to constitute the guitar 1, the neck 3 according to the present invention is a neck member 5, 5 made of wood ') Is formed by nutrient in the longitudinal direction, the reinforcing means is coupled between these neck members (5, 5').

Looking at the configuration of the present invention in detail as follows.

As shown in Figs. 3a and 3b, the neck member 3 is formed by dividing the neck members 5 and 5 'formed of wood as usual.

Then, the reinforcing means (4) is coupled between the neck members (5, 5 '), the reinforcing means (4) is mainly aluminum alloy and the like is completely different in material properties from both neck members (5, 5') Will be combined.

The reinforcing means 4 are naturally coupled to be located at the longitudinal center of the neck 3.

According to the present invention, the reinforcing means 4 is characterized in that the aluminum alloy is excellent stiffness, Duralumin, almost no deformation due to moisture or temperature changes.

Of course, the duralumin includes ultra duralumin, ultra duralumin, and the like, and it can be found that various alloys such as titanium and the like can be implemented.

The engaging surfaces 5a and 4a of the neck members 5 and 5 'and the reinforcing means 4 are mainly bonded to each other by using an adhesive or the like.

Looking at the bonding process through the bonding between the neck member (5, 5 ') of the wood and the reinforcing means (4) of the alloy as follows.

The neck members 5, 5 'made of wood and the reinforcing means 4 made of alloy are not properly bonded by simply bonding with an adhesive.

Therefore, both coupling surfaces 4a of the reinforcing means 4 coupled with the coupling surfaces 5a of the neck members 5 and 5 'are formed into rough surfaces with relatively rough sandpaper, and the speed of solidification is increased. After bonding using fast adhesive, they are strongly pressed toward the mutually bonded bonding surfaces 4a and 5a, and are solidified in a crimped state for at least 24 hours so that bonding is achieved.

In the above, forming the coarse surface of the engaging surface 4a of the reinforcing means 4 which is adhesively bonded to the engaging surface 5a of the neck members 5 and 5 'is the adhesion area with the neck members 5 and 5'. It is intended to have a strong adhesive strength by widening and by solidifying the physical properties of the adhesive to the bonding surface (4a) of the reinforcing means (4) relatively dense.

In the above adhesive, it is suitable to use methyl cyanoacrylate, ethyl cyanoacrylate or the like.

The reinforcement means 4 is naturally located at the longitudinal center of the neck 3 and is coupled over the entire length of the neck 3.

On the other hand, the neck (3) combined as described above is completed by the neck (3) through the usual work, such as processing to form the neck (3), as shown in Figure 4a, 4b, combined with the resonance box (2), the upper surface By combining the fingerboard 6, the guitar 1 is constituted.

In the above, the coupling structure between the neck 3 and the resonance box 2 is to be implemented in various ways, and since it is separate from the gist of the present invention, a reference to the coupling structure and the like thereof is omitted.

The present invention can be configured as described above, not only the pulling of the string of the guitar (1) but also the deformation of the torsion or warpage due to moisture or temperature change, etc., as well as the vibration of the resonance box (2) is a neck (3) It is not transmitted to the sound box, but the sound of the resonant box (2) itself is clear and clear sound.

The reinforcing means 4 coupled between the two neck members 5 and 5 'has excellent rigidity and hardly deformable due to temperature change or moisture, and thus is composed of duralumin, which is widely used as an airplane body material. Even if the flexural load is subjected to the pull of the string, the reinforcing means 4 does not cause the neck 3 to be bent or twisted by performing the supporting role in the center of the neck 3.

That is, even if the entire neck 3 is subjected to a strong deformation load by pulling on the string, the reinforcing means 4 integrally coupled with the neck 3 at the center of the neck 3 is applied to the deformation force of the neck 3. The corresponding strong stress acts to support the entire neck 3 so as to retain the original shape of the neck 3 despite the strain load caused by pulling the string.

In addition, since the reinforcing means 4 formed at the center of the neck 3 is made of a dense and rigid medium different from the two neck members 5 and 5 ', the vibration of the resonance box 2 is caused by the sound of the string. It is not transmitted to the neck 3 but is absorbed and vibrated in the resonance box 2 itself.

This is because the structure of the medium is blocked by the other reinforcing members 4 in the process of transmitting the wavelength of vibration due to the resonance of the resonance box 2 to the neck 3, so that the resonance box 2 is blocked. Without transmitting the vibration of the sound waves bounced to the outside to the outside of the resonance box (2) itself is absorbed and vibrated and output through the ringing sound will give a very clear and clean sound.

In addition to the above, the neck 3 according to the present invention is made of a rigid structure, while the vibration of the resonance box 2 is not transmitted, so that the vibration box of the resonance box 2 is partially transmitted and does not dissipate the wavelength of the sound. Absorption and vibration in the) to output the sound like a guitar consisting of a resonance box (2) without the neck (3) to ensure a very good sound quality.

As described above, the present invention adopts a reinforcing structure for reinforcing the neck 3 in a relatively simple configuration using aluminum alloy duralumin, which effectively prevents deformation such as bending, torsion, etc. due to string pulling, moisture, and temperature change. In addition, the vibration of the resonance box (2) according to the sound of the string is not transmitted to the neck (3) can obtain a very clear and clean sound.
