Description

Transposition guitar

Technical field

[0001] The present invention relates to a stringed instrument, in particular, a guitar.

Background technique

[0002] The guitar is a basic musical instrument. Its structure is roughly as shown in Figure 1. It includes a piano box 1, a neck 2, and a piano head 3; There are two strings 31, six strings 4 are drawn from the six strings 31, extend to the bridge 11, and are fixed by the fixing pins 110 on the bridge; the front of the neck 2 is the fingerboard , A series of frets 21 are fixed from top to bottom on the fingerboard; the upper part of the string 4 is pillowed on the upper pillow 211 provided at the end of the neck, and the lower part of the string 4 is pillowed on the piano The lower piano pillow 111 of the bridge 11; and the string 4 crosses the pickup hole 10 on the piano box 1. When the left hand does not press the string, and the right hand plucks the string, the vibration length of the plucked string is the section between the upper pillow 211 and the lower pillow 111; and when the left hand finger presses the string on the fingerboard , The vibration length of the string 4 is the section from the nearest fret below where the string is pressed to the lower pillow 111. For example, when point A in Figure 1 is pressed, the string goes from the fret 21A to the lower pillow This section of 111 vibrates; therefore, when the string is pressed at different positions, the length of its vibration is also different, corresponding to different pitches.

[0003] According to the twelve equal temperament, the vibration frequency between adjacent scales differs by a fixed scale factor, that is, the frequency of each scale is a geometric sequence; therefore, the length of the vibrating chord corresponding to each scale is also a geometric sequence. From above to below the fingerboard, it can be seen that the interval between adjacent fret 21 is gradually reduced.

[0004] In the actual performance of the guitar, due to the different modes used in various scores, for the convenience of performance, capo is usually used to clamp the six strings between two adjacent frets 21 ; In this way, using the same fingering as C major on the fingerboard under the capo, you can play scores in other modes. However, this method of tone sandhi needs to carry a capo, which is very inconvenient; and, after the left hand is moved down, the bending conditions of the left arm and left hand have undergone major changes, which will make beginners very uncomfortable; , After the capo is adopted, the visual effect is seriously affected, that is, it is very ugly, greatly reducing its performance in performance, and greatly reducing the appreciation.

[0005] In view of the above reasons, the application number is 201310010646.3, the name is a guitar that is easy to change the pitch, and a guitar that can quickly change the overall pitch of the guitar is proposed. The basic principle is that it can slide up and down by setting it on the bridge. Move the lower string pillow to quickly change the string length, thereby changing the vibration frequency of each string at the same time. However, as stated in paragraph 021 of the patent specification, the problem that this technical solution cannot solve is that when the pitch span is large, the interval deviation between the strings is large; for people with a more sensitive musical sense, even if it is The lower string pillow slides a short distance, and the interval deviation between the strings will be unbearable; therefore, in the pursuit of high-quality art, this kind of technical solution is actually difficult to gain a foothold. However, the original inventor never gave a corresponding solution or enlightenment in the specification, thus leaving a regret for the design.

Summary of the invention

[0006] In view of the above problems, the purpose of the present invention is to provide a tuning guitar, which can quickly and simply realize the overall tuning while ensuring the pitch of the guitar.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the tone-shifting guitar includes a piano box, a neck, and a piano head; It extends to the bridge provided on the piano box and is fixed by the fixing pins on the bridge; the upper part of the string rests on the upper string pillow at the upper end of the neck, and the lower part of the string rests on the lower string pillow on the bridge; the lower string The pillow can slide on the bridge along the axial direction of the neck; the underside of the upper string pillow and the neck are leaking; the surface of the neck is provided with a fingerboard, and the fingerboard is fixed with a fret; The fingerboard can slide along the axis of the neck.

[0008] Preferably, the two ends of the lower ball nut have sliders, and the sliders are matched with the ball nut sliding grooves provided on the bridge.

[0009] Preferably, both sides of the neck are provided with fingerboard sliding grooves extending along the axial direction of the neck, the fingerboard is in the shape of a sheet, and the thickness on both sides matches with the fingerboard sliding grooves, so that the fingerboard Can slide along the fingerboard chute.

[0010] Preferably, a thrust rod is connected between the lower chord and the fingerboard, and the thrust rod enables the bottom chord and the fingerboard to achieve synchronous axial displacement. Further, there are two thrust rods, which are in the shape of a strip, and are respectively arranged on the outer side of the 1st string and the 6th string, and the two thrust rods face each other.

[0011] Preferably, the lower pillow is a rotating shaft, and six ring grooves matching the strings are equally spaced distributed on the rotating shaft to constrain the strings laterally.

[0012] Preferably, a cross beam overhead above the strings is further provided above the lower chord, and the cross beam and the bottom chord are mutually restrained in the axial direction of the neck. When the cross beam is pushed and pulled along the axial direction of the neck, The lower bolster slides along the bolster sliding groove along the following beam.

[0013] The beneficial effect of the present invention is that: when using the guitar to perform a song that requires a capo, you only need to slide the fingerboard a corresponding distance along the fingerboard chute, so that the capo will be used when the capo is originally used. The first fret from the bottom slides up to below the top nut at the upper end of the neck; at the same time, the bottom nut slides up to the same displacement as the fingerboard; at this time, the performance of the performance is exactly the same as when the capo is used to ensure that the pitch is not deviation.

Detailed ways

[0018] The present invention will be further described below with reference to the drawings and embodiments:

[0019] Embodiment One:

[0020] In the first embodiment shown in FIG. 2, the pitch-changing guitar includes a piano box 1, a neck 2, and a piano head 3; The column leads out and extends to the bridge 11 provided on the piano box 1, and is fixed by the fixing pin 110 on the bridge 11; The lower string pillow 111 resting on the bridge 11; the string crosses the pickup hole 10.

[0021] The lower nut 111 can slide on the bridge 11 along the axial direction of the neck. In order to realize the sliding of the lower pillow 111, the lower pillow 111 is shown in FIG. The lower chord 111 is a rotating shaft, which is connected to the slider 112. The rotating shaft is equidistantly distributed with six ring grooves matching the strings to restrain the strings laterally. According to this solution, when the bottom pillow 111 slides, there is rolling friction between the bottom pillow 111 and the string, which greatly reduces the friction between the bottom pillow 111 and the string 4 and prevents the strings from being damaged. In addition, a cross beam 113 that is overhead above the strings is also provided above the bottom pillow 111, and the cross beam 113 and the slider H2 are fixed to each other, so as to realize the connection with the bottom pillow 111 in the axial direction of the neck. Mutual restraint; in this way, the string 4 is located between the lower string pillow I11 and the beam 113, when the beam 113 is pushed and pulled along the axis of the neck, the string 4 may not be touched, and the lower string pillow 111 follows the beam 113 along the The nut runner 111〇 slides.

[0022] There is an air gap between the lower side of the upper string pillow 211 and the neck 2; the neck surface is provided with a fingerboard, and the fret 21 is fixed on the fingerboard; the fingerboard can be along the neck 2 Axial sliding. In this way, the fingerboard can pass through the headrest 211 and slide towards the headstock 3. In order to realize the sliding of the fingerboard, both sides of the neck 2 are provided with fingerboard sliding grooves 20 extending in the axial direction of the neck. Matching, the fingerboard can slide along the fingerboard sliding groove 20; the fingerboard sliding groove extends from the neck 2 to the uppermost end of the head 3.

[0023] When using the above-mentioned guitar to perform a song that requires a capo, you only need to slide the fingerboard a corresponding distance along the fingerboard chute 20, so that when the capo is originally used, the first fret under the capo is The column slides up to below the upper string pillow 211 at the upper end of the neck; at the same time, the lower string pillow 111 is made to slide up by the same displacement as the fingerboard; at this time, the string vibration length becomes shorter, and the chord position of the original C major The distance between adjacent frets is also correspondingly smaller at the same time. According to the description of ordinary guitar principles in the background technology, it is easy to know that at this time, the guitar achieves the same effect as the capo without losing the pitch.

[0024] The second embodiment:

[0025] In the second embodiment shown in FIG. 3, the difference from the first embodiment is that a thrust rod 5 is connected between the lower pillow 111 and the fingerboard, and the thrust rod 5 makes the lower pillow 111 and the fingerboard realize synchronous axial displacement. At this time, as long as you push the fingerboard or the lower ring rest 111 according to the mode, so that the corresponding fret 21 on the fingerboard is aligned with the upper ring rest 211, the lower ring rest 111 or the fingerboard will automatically follow the adjustment, thus completing the mode adjustment in one step, greatly Facilitates the adjustment process.

[0026] As a preferred solution of the thrust rod 5, there are two thrust rods 5, which are in the shape of a strip, and are respectively arranged on the outer side of the 1st string and the 6th string, and the two thrust rods 5 face each other. According to this solution, the sound energy transmitted to both sides when the string 4 vibrates can be reflected back to the pickup hole 10 by the slat-shaped thrust rod and enter the interior of the piano box, thereby enhancing the sound of the guitar.

[0027] The foregoing descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention shall be included in the present invention. Within the scope of protection of the invention.
