Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for introducing guitar string vibrations into a vibrating body.

Conventional Guitar Structure and Problems 1 In conventional guitars, the vibration of the string is mainly introduced from the bridge to the vibrating body, and it is almost impossible to introduce it from the neck except in the high range. Since it is a one-place introduction method, the introduction power is insufficient. The most beautiful sound on a guitar is in the high range. The reason is that it suppresses the vicinity of the treble resonance body due to its high range. In other words, the string vibration is introduced from two places: the bridge and the neck.

Is there a way to satisfy this condition in all G ranges? 2. Structurally, conventional guitars have a neck on the top and side plates of the treble resonance body.
In order to fix it in place, reinforcing materials are inserted inside the structure, and fingertips are attached to the top plate, so the vibration of the top plate of the treble resonator body is inconvenient.

Is it a skill to remove them and make the front plate vibrate? In order to solve these problems, the guitar of this invention not only introduces string vibration from the bridge like conventional guitars, but also from the neck (3), thereby increasing its introduction power. is 1".

The guitar vibrating body of this invention adds a mid-tone resonator (7) to the conventional two-resonator guitar, making it a three-resonator vibrating body, and one acoustic hole is provided for each resonator body number (Figure 1). String vibration is also introduced from the neck (3), in addition to the traditional bridge. This is to change the conventional one-place introduction method to a two-place introduction method.

In addition, the playing style and posture can be changed to the conventional Kura 7 Noku guitar. ) and slightly to the left (after 12 degrees) respectively.

The back plate is also bent from the connecting part of each resonance body of the middle tone part (7) and the high back part (8), making the middle tone part resonance body oblique (Fig. 2), and the above-mentioned vibrating body. For the middle part, put a bridge (4) and a stand (1) on the top plate of the body (7), and a piece (5) and a stand (2) on the top plate of the treble part resonator body (8). -ni (3)
The structure is such that the string (In) vibration is also introduced from the rod (3) to the vibrating body.

In addition, the materials are the same as conventional guitars.

Means for Solving the Problems Regarding the above-mentioned problem No. 1, the introduction power of the string vibration can be increased by introducing the string vibration in two places. In other words, since the high range of a conventional guitar is suppressed near the treble resonance body, the string vibration is introduced from two places, the bridge and the neck, so it produces a good sound, so if you use this structure, you can achieve all-tone sincerity. will be fulfilled.

Regarding problem 2, as shown in Figure 2, the rod support stand (1
) (2), the neck (3), and the top plate of the vibrating body form a triangle, so the reinforcing material inside the treble resonator body against the pulling force of the conventional guitar structure is unnecessary, and Since it can be replaced with a strength tree, each resonator can be fitted with a dedicated strength tree suited to its range of sound. For the above reasons, I will wait (both treble parts are 11)
The top plate of the 13th body (8) can vibrate freely, making it possible to create a beautiful old-fashioned color.

Comparison between the prototype of the invention and the Yamaha GCIO (Yamaha) This guitar was purchased in 1972.The prototype of the invention has a veneer (plywood) top and back plate, and a lauan (single board) side plate.
, The neck (3), its base and bridge are made of pine, and the fingerboard is made of real wood.

As a result of comparing this with the Yamaha GC10, it is hard to believe that it is inferior in volume and sound quality.

Effects of the Invention Unlike conventional guitars, there is no reinforcing material inside the treble resonator body, and no fingerboard or the like is attached to the top plate, so the top plate can vibrate freely. The structure of the neck (3) placed on top of the top plate causes the string to vibrate together with the top plate.Therefore, the strings are higher than conventional guitars. It has the effect of preventing the string from rattling to some extent, and can give the string a stronger vibration!III.

As a result, the volume becomes a little louder. Because of the effect of preventing the strings from rattling, the guitar of this invention can be played more strongly than the Yamano XGC10, which has the same string height. In that sense, this guitar has a little more volume than the (Yamaha), but it can produce a stronger sound than a large seedling. If you play the same force, the strings of (Yama 1) will become jittery. The reason is that the neck is fixed to the treble resonance body.

Since the resonator body is larger and longer than before, the range of resonance within the body is wider, so at least the player can feel the sound of two guitars playing at the same time (the sound is powerful and heavy, giving a stereo effect).

When you play one note and immediately stop it, the other strings will resonate at that pitch.This is made of plywood and is made of Yamaha GCI.
It's a little better than O. This is an effect of the method of introducing string vibration in two places. ” As fact 1 proves, the pitch is accurate even if the bankosho (3) vibrates.
