Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
Pitch refers to the subjective perception of the human ear on the level of a tone, and is mainly determined by the level of frequency and the loudness. Wherein, the low-frequency tones give the feeling of heaviness, thickness and roughness to people, and the high-frequency tones give the feeling of beauty, brightness and sharp carving to people. Frequency, refers to the number of times a full vibration is completed per unit time. The relationship between frequency (f) and period (T) is: f is 1/T. The vibration period is related to the mass of the vibrator, and when the mass is smaller, the period is smaller. Therefore, when the weight of a certain position of the guitar panel is increased, the vibration period of the position is increased, and correspondingly, the frequency is reduced; when the weight of a guitar panel at a certain position is reduced, the vibration cycle at that position is reduced, and correspondingly, the frequency is increased.
According to the above principle, the utility model provides a guitar pitch adjustment structure, this structure includes guitar panel body 1, first horizontal sound roof beam 2. Wherein, seted up the sound hole 3 on the guitar panel body 1, first horizontal sound roof beam 2 is located the sound hole 3 below, and is perpendicular with the longitudinal axis of guitar panel body 1. The first transverse sound beam 2 is provided with a sliding groove 4 along the transverse direction of the guitar panel body 1, a sliding block 5 is arranged on the sliding groove 4, and the sliding block 5 is connected with the first transverse sound beam 2 in a friction fit mode. The slider 5 moves along the sliding groove 4 under the action of external force, and the slider 5 is still relative to the sliding groove 4 under the action of non-external force. Since the slider 5 has a certain weight, the guitar pitch adjusting structure changes the weight of the guitar panel in the lateral direction of the guitar panel body 1 by moving the slider 5, thereby affecting the vibration frequency of the corresponding panel. When the sliding block 5 is slid to a certain position of the guitar panel, the weight of the panel corresponding to the point is increased, and correspondingly, the vibration frequency of the panel at the position is decreased; in contrast, if the slide 5 is away from this point, the panel weight corresponding to this position becomes small, and accordingly, the panel vibration frequency at this position becomes large. Therefore, compared with the existing guitar, the guitar provided with the pitch adjusting structure meets the playing requirements of music scores of different styles by changing the weight of a certain position of the guitar panel.
In practical application of the guitar, since the six strings of the guitar are also arranged in sequence along the transverse direction of the guitar panel body 1, from top to bottom, the bass region to the treble region. Assume that the junction of the bass zone and the treble zone is a high-low zone dividing point, the midpoint of the treble zone along the transverse direction is a treble zone midpoint, and the midpoint of the bass zone along the transverse direction is a bass zone midpoint. When the sliding block 5 moves from the bass-bass demarcation point to the treble zone midpoint, the panel weight at the treble zone becomes large, the corresponding frequency becomes small, and the sound in the treble zone becomes relatively low during playing. Since the vibration of the middle of the guitar panel is the main factor affecting the guitar's pronunciation and the vibration of the guitar panel's edge has less effect on the guitar's pronunciation, when the slider 5 is moved further down from the middle of the treble to the treble near the panel's edge, although the weight of the treble near the panel's edge becomes larger, the change in treble sound during playing will not have a great effect. It can be seen that changes in guitar panel weight at the mid-treble have the greatest effect on changes in treble sound while playing.
Likewise, the bass region is also the same: when the sliding block 5 moves from the high and low sound dividing point to the middle point of the low sound zone, the weight of the panel at the low sound zone becomes large, the corresponding frequency becomes small, and the sound of the low sound zone becomes relatively low during playing. When the slider 5 is further moved upward from the midpoint of the bass region toward the panel edge of the bass region, although the weight of the bass region near the panel edge becomes large, the change in the sound of the bass region during playing does not have a great influence. It can be seen that changes in the weight of the guitar panel at the midpoint of the bass zone have the greatest effect on the change in the bass zone sound while playing.
When the music instrument is used, a user directly extends fingers into the sound hole 3, stirs the sliding block 5 on the first transverse sound beam 2, plays strings and judges whether the music is required by the user; if the fingers can not be directly inserted, the strings can be loosened to vacate the position, and then the fingers are inserted from the sound holes 3 for adjustment. Since the slider 5 is connected with the first transverse sound beam 2 in a friction fit manner, the slider 5 is stationary relative to the first transverse sound beam 2 under the action of no external force, and therefore, a user does not need to worry about the displacement of the slider 5 during playing.

In this embodiment, the first transverse beam 2 is placed 7.5-8.5mm, preferably 8mm, below the soundhole 3. The first transverse beam 2 divides the guitar panel into two parts, an upper part provided with sound holes 3 and a lower part not provided with sound holes 3. Wherein, the guitar panel of the upper part has little influence on the guitar pronunciation. Since the force applied to the upper part is large due to the tension of the guitar strings, the guitar panel of this embodiment is further provided with a second transverse beam 6 and a third transverse beam 7 in order to increase the strength of the guitar panel. The second transverse sound beam 6 is arranged 7.5-8.5mm above the sound hole 3, preferably 8 mm; the third transverse sound beam 7 is positioned 34.5-35.5mm, preferably 35mm, above the second transverse sound beam 6. The first transverse sound beam 2, the second transverse sound beam 6 and the third transverse sound beam 7 are 7mm wide and 15mm high, and the error is within plus or minus 0.5 mm. Second, vibration of the guitar panel of the lower portion is an important factor affecting the guitar's pronunciation. A vertical sound beam 8 is further arranged along the longitudinal axis of the guitar panel body 1, a first oblique sound beam 9 is arranged on the left side of the vertical sound beam 8, the upper end of the first oblique sound beam 9 is close to the vertical sound beam 8, and the lower end of the first oblique sound beam 9 is far away from the vertical sound beam 8; the right side of the vertical sound beam 8 is provided with a second pitch beam 10, and the first pitch beam 9 and the second pitch beam 10 are symmetrically arranged by taking the vertical sound beam 8 as a symmetry axis. That is, the first pitch bell 9 and the second pitch bell 10 are designed in a "chevron" shape to better accommodate the direction of sound propagation. In this embodiment, the width of the pitch bell is 4mm, the height is 4.5mm, and the error is within plus or minus 0.5 mm. Wherein the number of the first pitch bell beams 9 is preferably 2-3, and the number of the second pitch bell beams 10 is the same as the number of the first pitch bell beams 9.
Further, as shown in fig. 2, 3 and 4, in order to make the adjustment range larger, the slide 5 in the present embodiment is provided as a double number, for example, two or four. Of these, the number of the sliders 5 in the present embodiment is preferably two. In the embodiment, each slider 5 is 18-20mm long along the transverse direction of the guitar panel body 1, 10-12mm wide along the longitudinal direction of the guitar panel body 1, and 9.5-10.5mm thick. The material of the slider 5 is the same as the material of the first transverse sound beam 2, and both are made of wood, and in the embodiment, the slider 5 is preferably made of spruce.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
