A guitar body loop structure and guitar

Abstract

The present invention provides a loop structure in the guitar body, wherein the guitar body comprises a panel, a bottom plate and a curved side plate, and loops with corresponding curvature are provided on the inner edges of both sides where the curved side plate intersects with the panel and the bottom plate, and the width of the grooves distributed on the loops is reduced to 0.5 to 0.25 times of the original width, but the width of the grooves at the notch in the loop is greater than the width of the grooves at the non-notch. The present invention reduces the width of the loop grooves on both sides of the curved side plate to one-half to one-quarter of the original width, so that the contact area between the side plate and the panel, and between the side plate and the bottom plate increases by about 20%, significantly reducing the probability of the side plate and the panel or the bottom plate being separated, and improving the bonding tightness; and, because the loop grooves become smaller, they are more beautiful than the loops with the original width when viewed from the sound hole, and glue is prevented from overflowing from the grooves. When the guitar is provided with a notch, the groove width of the loop at the notch maintains the original width, or is wider than the original width, so as to ensure that the loop at the notch can bend.

Description

Technical Field

[0001] The invention relates to the technical field of guitar loop structures, and in particular to a guitar body loop structure and a guitar. Background Art

[0002] Guitar is a plucked string instrument, most of which are six-string guitars. Guitars can be divided into electric guitars and acoustic guitars. An acoustic guitar is composed of a headstock, a fingerboard, and a body. The strings are installed between the pegs and the lower bridge, and the frets are installed on the fingerboard. When playing, the fingers press different strings onto different frets, and the other hand plucks the strings to produce different tones. At present, the groove width of the curved loop set on the inner edges of both sides of the curved side panels is generally uniformly about 2.0 mm. Due to the large groove width, the contact area between the side panel and the panel, and the side panel and the bottom panel becomes smaller, affecting the bonding tightness; and when bonding the panel and the side panel, and the panel and the bottom panel, excess glue will enter the groove, which can be clearly seen from the sound hole, affecting the appearance of the guitar. Summary of the invention

[0023] The following specifically describes the embodiments of the present invention in conjunction with the accompanying drawings, which are only for reference and illustration and do not constitute a limitation on the scope of patent protection of the present invention.

[0024] Example 1 :

[0025] like Figure 1 , 2 As shown, this embodiment provides a loop structure inside the body of a rounded-corner guitar, wherein the body 10 includes a panel 1, a bottom plate 2 and a curved side plate 3, and loops 4 with corresponding curvatures are provided on the inner edges on both sides where the curved side plates 3 intersect with the panel 1 and the bottom plate 2, and the width of the grooves 40 distributed on the loops 4 is reduced to 0.5 to 0.25 times of the original width.

[0026] In this embodiment, the original width of the loop 4 is 2.0 mm. Figure 2 As shown, the width of the grooves 4 distributed on the loop 4 is reduced to 0.25 times of the original width, that is, 0.5 mm.

[0027] like Figure 3-1 , 3-2 As shown, the groove width of the existing loop with 10 loop points is reduced from 2 mm to 0.5 mm. The loop area before and after the groove width is changed is compared as follows:

[0028] When the groove is opened 2 mm, the area of ​​the 71 mm long loop is 268.7 square millimeters. When the groove is opened 0.5 mm, the area of ​​the same length of loop is 321.5 square millimeters. The area increase ratio is calculated as follows:

[0029] 321.5-268.7=52.8 / 268.7=19.7%

[0030] After counting dozens of guitars with no missing corners, the minimum arc radius R is 61.3 mm. After calculation, it is found that as long as the loop has a 0.5 mm groove, it can be used for all the guitars counted. Reducing the groove width of the loop to 0.5 mm increases the contact area between the side panel and the top panel, and between the side panel and the bottom panel by nearly 20%, significantly reducing the chance of separation between the side panel and the top panel, and between the side panel and the bottom panel, and improving the bonding tightness. By opening a 0.5 mm groove in the loop and sticking it to the side panel, the groove width will be smaller after the side panel is bent. From the sound hole, it is obviously more beautiful than the loop with a 2 mm groove width, and it can also prevent glue from overflowing.

[0031] like Figure 4-1 , 4-2As shown in 5-1 and 5-2, in this embodiment, the inner walls of the panel 1 and the bottom plate 2 of the piano body 10 are attached with power wood 51, 52, the panel 1 of the piano body 10 is provided with sound holes 6 and lower bridges 7, the upper end of the piano body 10 is connected with a fingerboard 8 and a headstock 9, a string 70 is installed between the string pegs 90 on the headstock 9 and the lower bridge 7, and frets 80 are installed on the fingerboard 8.

[0032] In this embodiment, a guard plate 60 is further provided next to the sound hole 6 , and an upper nut 71 and a lower nut 72 are provided at both ends of the string 70 .

[0033] In this embodiment, a lower code light 73 is provided on the lower code 7.

[0034] The present invention also provides a rounded-corner guitar 100, wherein the body 10 of the guitar 100 includes a panel 1, a bottom panel 2 and a curved side panel 3, and a loop 4 with a corresponding curvature is provided on the inner edges of both sides where the curved side panel 3 intersects with the panel 1 and the bottom panel 2, and the width of the grooves 40 distributed on the loop 4 is reduced to 0.5 to 0.25 times of the original width.

[0035] like Figure 4-1 , 4-2 As shown in 5-1 and 5-2, in this embodiment, the inner walls of the panel 1 and the bottom plate 2 of the piano body 10 are attached with power wood 51, 52, the panel 1 of the piano body 10 is provided with sound holes 6 and lower bridges 7, the upper end of the piano body 10 is connected with a fingerboard 8 and a headstock 9, a string 70 is installed between the string pegs 90 on the headstock 9 and the lower bridge 7, and frets 80 are installed on the fingerboard 8.

[0036] In this embodiment, a guard plate 60 is further provided next to the sound hole 6 , and an upper nut 71 and a lower nut 72 are provided at both ends of the string 70 .

[0037] In this embodiment, a lower code light 73 is provided on the lower code 7.

[0038] Example 2 :

[0039] The difference between this embodiment and embodiment 1 is that:

[0040] like Figure 6 As shown, this embodiment provides a loop structure inside the guitar body of a cutaway guitar, wherein the guitar body 10 includes a panel 1, a bottom panel 2 and a curved side panel 3, and loops 4 with corresponding curvatures are provided on the inner edges of both sides where the curved side panel 3 intersects with the panel 1 and the bottom panel 2, and the width of the grooves 40 distributed on the loop 4 is reduced to 0.5 to 0.25 times of the original width, but the width of the groove at the cutaway corner R in the loop 4 is greater than the width of the groove at the non-cutaway corner.

[0041] In this embodiment, the width of the groove at the notch R in the loop is 1 to 1.5 times the original width.

[0042] In this embodiment, the original width of the loop line 4 at the non-missing corner is 2.0 mm, and the width of the groove 4 distributed on the loop line 4 at the non-missing corner is reduced to 0.25 times the original width, that is, 0.5 mm, while the width of the groove at the missing corner in the loop line 4 is still 2.0 mm to ensure that the R loop line at the missing corner can bend.

[0043] The present invention also provides a cutaway guitar 100, wherein the guitar body 10 of the guitar 100 comprises a panel 1, a bottom plate 2 and a curved side plate 3, and a loop 4 with a corresponding curvature is provided on the inner edges of the curved side plate 3 at the junction of the panel 1 and the bottom plate 2, and the width of the groove 40 distributed on the loop 4 is reduced to 0.5 to 0.25 times of the original width. However, the width of the groove at the cutaway R in the loop 4 is greater than the width of the groove at the non-cutaway position.

[0044] In this embodiment, the width of the groove at the notch R in the loop is 1 to 1.5 times the original width.

[0045] In this embodiment, the original width of the loop line 4 at the non-missing corner is 2.0 mm, and the width of the groove 4 distributed on the loop line 4 at the non-missing corner is reduced to 0.25 times the original width, that is, 0.5 mm, while the width of the groove at the missing corner R in the loop line 4 is still 2.0 mm to ensure that the loop line at the missing corner can bend.

[0046] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
