Description

  The present invention relates to a saddle, a piece, a fret, and a nut material of a stringed instrument, and more particularly to a saddle used for an acoustic tech guitar or a classical guitar.

  Stringed instruments such as acoustic guitar, classical guitar, violin, cello, shamisen, etc., which are most popular among stringed instruments, are said to be saddles and pieces. Traditionally, saddles and pieces have been made of natural materials such as wood, beeskin, ivory and cow bones. However, in recent years, ivory has become difficult to obtain and has become very expensive and has disappeared from the market. Currently, wood, cow bones, and easy-to-mold and inexpensive plastics are the mainstream. Others have a titanium plate sandwiched between saddle bridges.

JP2008-15441

  Taking an example with an acoustic guitar, the saddle receives the vibration of the strings, amplifies the vibration with the space part of the trunk of the acoustic guitar and the resonance plate, and the sound comes out from the circular hole in the center of the trunk. If a saddle is made of wood, cow bone or the like having a fine cavity inside (corporal), it absorbs vibrations, so sound transmission is not good. If the saddle is made of a material that easily attenuates vibration, such as plastic, the transmission of vibration is not good. Also, plastic saddles and pieces deteriorate quickly because of severe wear due to string compression. Also, the shape may be deformed and become unusable when the temperature rises, such as in summer.

  The present invention is a saddle, piece, fret, and nut, wherein at least one of the saddle, piece, fret, and nut of the stringed instrument is made of a Group 11 metal, an alloy of Group 11 metal, or metal glass. .

  The present invention is a stringed instrument using the saddle, piece, fret, and nut.

The present invention is a saddle characterized in that a plurality of convex portions are provided at the bottom of the saddle.

  The present invention is a saddle characterized in that a saddle having a plurality of convex portions at the bottom is attached to a bridge with a spacer interposed therebetween.

  The present invention is an acoustic or classical guitar characterized by using the saddle.

  Use of Group 11 metal, Group 11 metal alloy or metal glass with high elastic strain energy and low damping rate for saddles, pieces, frets, nuts, treble, bass, medium sound, reverberation (sustain) ) Will be better. In addition, high, low and medium sounds are likely to be produced.

  By attaching a number of protrusions at the bottom, the sound becomes clear and bright, and the sound becomes dynamic, improving the balance between low, medium, and high sounds. In addition, the height of the saddle can be freely adjusted by using a spacer. Also, it does not deform even when the temperature rises such as in summer.

XX sectional view of the acoustic tech guitar of FIG. The front view of the saddle and the spacer which provided the convex part in the bottom part of Example 2 of this invention

  Example 1 and Example 2 of the present invention will be described with reference to FIGS.

  In the acoustic tech guitar as shown in FIG. 4, the string 6 is attached from the bobbin 9 through the upper part of the nut 1 to the trunk (body) of the acoustic tech guitar via the bridge 5. The frets 2 are attached to the neck portion of the acoustic tech as shown in FIGS. The mounting interval between the frets 2 becomes narrower as it approaches the hole 10. As shown in FIG. 5, the string 6 is attached to the trunk portion by providing a groove in the bridge 5 provided with the trunk portion (body) and attaching the saddle 3 to the groove. As shown in FIG. 5, the string 6 is stretched by fixing the string 6 to the saddle 3 with a string retaining pin 4. In acoustic tech guitars, the strings 6 to be stretched are usually six from the thinnest first string to the thickest sixth string.

  The saddle 3 is made of a Group 11 metal alloy. As shown in FIG. 7, a plurality of convex portions are provided on the bottom of the saddle 3, and when the saddle 3 is attached to the bridge 6, the spacer 8 shown in FIG.

  Next, the sound results of the conventional plastic saddle, the Group 11 metal alloy saddle of Example 1, and the metal glass saddle of Example 2 will be described with reference to FIGS.

  1 and 2 are frequency band distribution diagrams. FIG. 1 is a frequency band distribution diagram in which the cord C is played when a plastic saddle is used, a group 11 metal alloy saddle is used, and a metal glass saddle is used. Compared with plastic saddles, Group 11 metal alloy saddles sound more dynamic with the frequency range of 100 to 500 Hz in the bass part being emphasized.

  When a Group 11 metal alloy saddle is used, the region between 125 Hz and 500 Hz becomes clearer, and the low range below 125 Hz is also pronounced. Looking at the middle and high frequencies above 500 Hz, especially between 500 Hz and 4 KHz is pronounced more clearly than when using a plastic saddle. By using a Group 11 metal alloy saddle, it can be seen that the vibration and resonance of the saddle and the string are amplified and the sound is well balanced.

  Compared with a plastic saddle and a Group 11 metal alloy saddle, the metallic glass saddle is more emphasized in the frequency band of 100 Hz to 1.5 kHz, and can obtain a bright and brilliant sound.

  Next, the case where there is a convex portion at the bottom of the saddle and the case where there is no convex portion will be described. FIG. 2 is a frequency band distribution diagram in the case of sounding with the chord C of an acoustic tech guitar using a group 11 metal alloy saddle and a metallic glass saddle with or without a convex portion. The upper part is a Group 11 metal alloy and the lower part is metallic glass. The left side has no convex part and the right side has a convex part.

(Group 11 metal alloy saddle)
A saddle without a convex part sounds as a whole reverberatingly, but it cannot be reverberated with only a low-frequency emphasis in a low frequency band of 100 to 500 Hz. The saddle with a convex portion emphasizes the bass portion of 100 to 500 Hz and emphasizes the position of the guitar, so that the overall sound resonates and the sound is dynamic and the sound is well balanced.

(Metal glass saddle)
A saddle without a convex portion sounds as a whole reverberatingly well, but it does not give a well-balanced sound only by emphasizing the band of the sound component of 100 to 500 Hz. The sharpness of the sound is more pronounced when there is a convex part. In the frequency band of 1 to 4 kHz of the high-frequency sound component, the bright sounding part becomes even clearer. Sound components are also emphasized in the frequency band outside the audible range of 4 to 8 kHz.

FIG. 3 shows the relationship between the elastic strain energy δ ² / E and the damping rate η. When the elastic strain energy is high, the damping rate tends to be small. In addition, the sound is more likely to be heard when the attenuation rate is small. Therefore, the higher the elastic strain energy, the better the sound will sound.

  In FIG. 3, the brass of the Group 11 metal alloy is in the same position as the bronze. The Group 11 metals gold, silver, and copper are also in the same position. On the other hand, since the metallic glass has a very large elastic strain energy, the damping rate is very small. Therefore, it is best to use metallic glass. In contrast, the elastic strain energy is so small that plastic cannot be described in FIG. 3 (about 1 / 100th that of the Group 11 metal and its alloys), so the damping rate becomes large.
