Abstract

(57) [Summary] [Purpose] To provide a fingerboard for a stringed instrument having excellent wear resistance and corrosion resistance. [Structure] A predetermined number of strings 2 and this string 2 at a predetermined position
And a fret 4 made of a shape memory alloy of a Ti-Ni alloy. Since the fret is made of a shape memory alloy, which is more excellent in wear resistance and corrosion resistance than the conventional metal fret, the fret wears less and prevents the pitch deviation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fingerboard for a stringed instrument having frets.

[0002]

[Prior Art]

 A stringed instrument with a neck generally has a certain number of strings stretched around the neck. While holding down a specific part of the string on the neck, play the string on the instrument body with a bow, pick, drumstick, claw, etc. A specific sound can be generated. Violin string instruments do not have high or low marks on the neck, so that the performer can obtain the correct pitch by adjusting the string and the precise position.

On the other hand, string instruments of the lute genus such as a guitar and a mandolin are provided with a metal cross beam (fret) on the neck, and each fingerboard partitioned by the fret corresponds to a specific sound. Therefore, the correct pitch can be obtained relatively easily.

[0004]

[Problems to be solved by the device]

 However, in such a conventional fingerboard for a stringed instrument, since the fret is made of metal, when used for many years, the fret gradually wears out due to contact with the string, and the pitch becomes deviated, so that the correct pitch can be obtained. Not only could it not be done, but rust and stains caused by sweating from the fingers were remarkable.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a fingerboard for a stringed instrument having excellent wear resistance and corrosion resistance.

[0006]

[Means for Solving the Problems]

 A fingerboard for a stringed instrument according to the present invention for solving the above-mentioned problems is characterized by comprising a predetermined number of strings and a fret made of a shape memory alloy that supports the strings at predetermined positions.

[0007]

[Action]

 According to the fingerboard for a stringed instrument according to the present invention, the fret made of the shape memory alloy is superior in wear resistance and corrosion resistance to the conventionally used metal fret, so that the fret is less worn and the pitch is changed. prevent.

[0008]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment in which a string fingerboard according to the present invention is applied to a guitar. The guitar usually has six strings. The string 2 is wound in a one-to-one correspondence with the bobbin 3 provided at the tip of the neck 1, and then stretched in a straight line from there through the neck 1 toward the instrument body. Further, the string 2 passes through the upper portion of a hole (hole) (not shown) provided at the center of the main body and is fixed so as not to come off to the lower end of the main body. If the player is a right-handed person, he can press each fingerboard 5 formed by dividing the neck 1 by the frets 4 with his left finger, and by striking the strings at the top of the body hole with his right hand nail or pick. Get the pitch of.

The fret 4 is composed of a Ti—Ni alloy, which is a type of shape memory alloy. Comparing the frets of the above-described example with the conventional frets, the frets of the above-described examples have the advantages that they have excellent corrosion resistance, are resistant to rust even if a finger sweats, and are resistant to stains. The frets 4 are formed of a Ti-Ni alloy, but it goes without saying that other shape memory alloys may be used.

[0010]

[Effect of the device]

 As described above, according to the fingerboard for a stringed instrument of the present invention, the fret made of a shape memory alloy having excellent wear resistance and corrosion resistance is provided, which must be avoided when playing a musical instrument. It has the effect of avoiding fret wear, which is one of the causes of pitch deviation, and prevents fret rust and dirt.
