Abstract

PROBLEM TO BE SOLVED: Iron wires are heretofore used successively from a pitch side for the strings of musical instruments, such as violins, violas, cellos, contra basses, guitars, mandolins and harpsichords, and gut or nylon wires are used toward lower tones and since the iron wires or the like used on the pitch side are iron, the wires are heavy and have a high modulus of elasticity and, therefore, these wires are desired to be made as light as possible from the standpoint of users; in addition, the fine adjustment of tones is difficult and the novel string materials therefrom are required to be light, strong and durable, are free of environmental problems and the timbres generated therefrom must be beautiful. SOLUTION: The replacement of the portions of the iron wires on the pitch side used heretofore with the string of this invention is easy and since this string has nearly the same tensile strength as the tensile strength of the iron wires, the string is lighter than the iron and since its modulus of elasticity is small, the fine adjustment of the varying interval of the tones on pegs, etc., is easy. Since the string is highly corrosion resistant, the string does not rust and is highly durable. The string produces the beautiful timbres.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the use of iron wire or gut (nymph) or nylon wire conventionally used for strings of musical instruments such as violin, viola, cello, double bass, guitar, mandolin, harp and the like. Instead, it relates to a new, lighter, stronger and easier to use titanium and titanium alloy wire. By using the titanium and titanium alloy wires, it is possible to emit lighter and easier-to-use and more durable and beautiful tones than ever before.

[0002]

2. Description of the Related Art Conventionally, strings of musical instruments such as violins, violas, cellos, contrabass, guitars, mandolins, harps, and the like have been made of iron wire from the treble side. They are used, and thin wires of aluminum, gold, silver, etc. are wrapped around them.

[0003]

Of these, iron wires and the like used particularly on the treble side are heavy since they are iron and have a high elastic modulus. Problems have been pointed out, such as wanting to be light and difficult to fine-tune only 9 sounds. Gut on the bass side is not preferable from the viewpoint of natural environment such as animal welfare, and nylon is not preferable from the viewpoint of waste. Thus, the string materials conventionally used for them have many problems. New string materials from now on should be light, strong, durable, safe for the natural environment and have a beautiful tone.

[0004] Therefore, there is a strong demand for the development of a string material that is light, strong and durable even a little, and also in this field, there is a little problem in terms of material recycling.

[0005]

Means for Solving the Problems The present inventor has conducted various studies on conventional string materials in order to solve the above-mentioned problems, and as a result, titanium and a titanium alloy have been used instead of the conventional string materials to manufacture the string materials. The present invention has been completed by noting that it has extremely excellent properties in terms of its mechanical properties.

The present invention relates to violins, violas, cellos,
It is a light, strong, durable material that replaces the traditional iron or gut, nylon wire used in strings of musical instruments such as contrabass, guitar, mandolin, harp, etc., and It relates to titanium and titanium alloy wires which are easy to use.

In the present invention, the titanium and titanium alloy wires are pure titanium for industrial use or aluminum,
The wire is made of a material containing an alloy component such as vanadium, chromium, molybdenum, zirconium, and tin. In the case of an alloy, the types of components contained therein are not limited. The titanium and titanium alloy wires are applied to strings for musical instruments (or sometimes referred to as wires). Alternatively, the wire of the present invention may be used as a core wire wound with another thin material wire.

The titanium and titanium alloy wires of the present invention have different crystal structures and manufacturability depending on the components contained therein, but they may be used properly depending on the application. Therefore, the crystal structure is a material mainly having one or both of a dense hexagonal lattice (abbreviated as HCP) and a body-centered cubic lattice (BCC).

The musical instrument using a string in the present invention includes a violin, a viola, a cello, a double bass, a guitar, a mandolin, a harp, and a musical instrument using many iron wires such as a piano. The method of application is not particularly limited, but since it has almost the same tensile strength as a conventionally used iron wire on the high sound side, it is easy to replace the wire of the present invention in this portion. And because it is lighter and has a lower elastic modulus than iron, it is easy to fine-tune the pitch of the sound with a pincushion, etc., and because it has excellent corrosion resistance, it has excellent durability without rusting the strings, It emits beautiful tones and beautiful tones.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to violin, viola,
Light, strong and durable to replace the traditional steel or gut and nylon wires used in strings of musical instruments such as cello, contrabass, guitar, mandolin, harp, etc. And easy-to-use titanium and titanium alloy wires.

The main body of the stringed instrument can be used as it is,
For a musical instrument such as a violin that must be supported by a shoulder or an arm for a long time, it is better to use a little lighter, and the use of the string according to the present invention is effective.

[0012]

Example 1 As an example of a titanium and titanium alloy wire, a violin string wire was prepared. That is, industrial pure titanium JIS class 2 material (having a crystal structure of HCP), and titanium alloy of 3% aluminum, vanadium 2.
Alloy containing 5% (having two phases of HCP and BCC) or titanium 3% aluminum, vanadium 8%, chromium 6%, molybdenum 4%, zirconium 4%
Rolled a total of four types of alloys, including alloys containing 3% aluminum, 15% vanadium, 3% chromium, and 3% tin in titanium (all of which have a BCC crystal structure)
Draw, heat-treat as needed, add 0.2mm diameter
It was a thin line within the range of 0 mm to 0.50 mm. As a result, all of these wires were lighter than conventional iron wires for strings having the same diameter, and the result was that the strings could be easily wound and the tone was good.

[0013] Similar lines have been tried for strings of viola, chiero, contrabass, guitar, mandolin and harp, all with good results. It can also be applied to piano wires.

[0014]

Since the present invention is configured as described above, it has the following effects.

First, according to the present invention, a light, strong and easy-to-use titanium and titanium alloy wire is applied to the lines of musical instruments such as a violin, viola, cello, double bass, guitar, mandolin, harp and the like. ,
It is lighter, easier to use, and more durable than before, and can provide a beautiful tone equal to or better than that of the past.
