Abstract
Description
Technical Field
[0001] This utility model relates to the field of wooden guitar technology, specifically to a guitar soundboard with an arc-shaped sound bar and a guitar. Background Art
[0002] Wooden guitars transmit sound by receiving the vibrations of the strings through the body and converting these vibrations into vibrations on the soundboard. At the same time, the soundboard also acts as an acoustic equalizer for the strings, which can amplify certain notes and filter out others. Therefore, the soundboard is an important component of wooden guitars.
[0003] In order for the soundboard to respond quickly to vibrations, it must be lightweight enough while also being able to withstand significant tensile forces. Therefore, the soundboard must possess sufficient toughness and strength. To increase the strength of the soundboard without increasing its weight, support beams are typically installed on the soundboard of wooden guitars. In practical use, it has been found that the support beams can also influence the guitar's tone by controlling the vibrations of the soundboard.
[0004] Existing wooden guitars typically have a trapezoidal or "X"-shaped support beam on the soundboard to reduce its weight while maintaining its high toughness and strength. To further improve sound quality, multiple auxiliary beams are needed to optimize sound propagation, which further increases the overall weight of the guitar and is detrimental to the structural stability of the soundboard.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.
[0030] Example 1:
[0031] Please refer to Figure 1 This embodiment provides a guitar soundboard with an arc-shaped sound bar, including a soundboard 10. The soundboard 10 has a sound hole 11, which has a circular cross-section in this embodiment. An upper sound bar 21 and a lower sound bar 22 are provided on the back of the soundboard 10; the upper sound bar 21 and the lower sound bar 22 are arranged side by side below the sound hole 11.
[0032] The upper sound beam 21 is a smooth arc shape that arches downward in the middle and extends upward at both ends; the two ends of the upper sound beam 21 extend to the upper edge of the sound plate 10 respectively; the lower sound beam 22 is a smooth arc shape that arches upward in the middle and extends downward at both ends; the two ends of the lower sound beam 22 extend to the lower edge of the sound plate 10 respectively. That is to say, the upper sound beam 21 is a flat arch shape that lowers in the middle and rises at both ends, and the lower sound beam 22 is a flat arch shape that rises in the middle and lowers at both ends, and the two are symmetrically fixed below the sound hole 11.
[0033] The guitar soundboard with curved sound beams in this embodiment provides higher mechanical strength and rigidity through the curved upper sound beam 21 and lower sound beam 22 on the back of the soundboard. This helps support the guitar soundboard and prevent deformation, maintaining stability during vibration and thus enhancing sound resonance. The curved sound beam design helps optimize sound propagation, enabling the guitar to produce a more uniform tone and greater volume, effectively transmitting and amplifying sound waves, resulting in a richer tone and greater volume. The curved upper sound beam 21 and lower sound beam 22 can provide sufficient support with less material, helping to reduce the overall weight of the guitar while maintaining the structural stability of the soundboard.
[0034] The upper sound beam 21 and the lower sound beam 22 have the same curvature. By setting the upper sound beam 21 and the lower sound beam 22 to be arcs with the same curvature but opposite opening directions, symmetry between the two is ensured, thereby producing a more uniform sound quality.
[0035] In this embodiment, a left wing beam 31 and a right wing beam 32 are symmetrically arranged below the sound panel 10; the left wing beam 31 and the right wing beam 32 are arranged on opposite sides below the sound panel 10. The wing beams further improve the structural stability of the bottom of the sound panel 10. Specifically, the left wing beam 31 is a smooth arc shape that arches towards the center of the sound panel 10 in the middle and extends towards the left edge of the sound panel 10 at both ends; the right wing beam 32 is a smooth arc shape that arches towards the center of the sound panel 10 in the middle and extends towards the right edge of the sound panel 10 at both ends.
[0036] The left wing beam 31 is intersected with the lower sound beam 22, and the intersection of the left wing beam 31 and the lower sound beam 22 forms a connection point; the right wing beam 32 is intersected with the lower sound beam 22, and the intersection of the right wing beam 32 and the lower sound beam 22 forms a connection point; the curvature of the left wing beam 31 and the right wing beam 32 is the same; the left wing beam 31 and the right wing beam 32 are arranged symmetrically on the left and right sides.
[0037] By cross-connecting the left wing beam 31 and right wing beam 32 to the lower sound beam 22, they work together to provide a more robust and resonant structure. The upper sound beam 21 and lower sound beam 22 provide structural stability to the entire soundboard 10, while the left wing beam 31 and right wing beam 32 primarily provide additional support to the bottom. During performance, as vibrations are transmitted through the soundboard 10, the curved structure of the upper sound beam 21 and lower sound beam 22 enhances the resonance of the soundboard, while the left wing beam 31 and right wing beam 32 help distribute pressure, resulting in a fuller tone at the bottom, especially in the low-frequency range, thus improving the overall sound performance.
[0038] The guitar soundboard with an arc-shaped soundbar in this embodiment also includes a string bridge auxiliary beam 40, which is disposed below the lower soundbar 22. One end of the string bridge auxiliary beam 40 is connected to the left wing beam 31, and the other end is connected to the right wing beam 32. Fixing the string bridge auxiliary beam 40 within the area enclosed by the lower soundbar 22, the left wing beam 31, and the right wing beam 32 better counteracts the force exerted by the guitar strings on the soundboard 10 through the string bridge auxiliary beam 40.
[0039] Furthermore, it also includes a crossbeam 50, a first auxiliary beam 61, and a second auxiliary beam 62; the crossbeam 50 is horizontally positioned above the sound hole 11; both ends of the crossbeam 50 extend to the upper edge of the sound plate 10. The first auxiliary beam 61 and the second auxiliary beam 62 are arranged in a V-shape on the left and right sides of the sound hole 11.
[0040] The upper end of the first auxiliary beam 61 is connected to the crossbeam 50. The first auxiliary beam 61 is intersected with the upper sound beam 21 and the left wing beam 31, respectively, and connection points are formed at the intersections of the first auxiliary beam 61 with the upper sound beam 21 and the left wing beam 31. The upper end of the second auxiliary beam 62 is connected to the crossbeam 50. The second auxiliary beam 62 is intersected with the upper sound beam 21 and the right wing beam 32, respectively, and connection points are formed at the intersections of the second auxiliary beam 62 with the upper sound beam 21 and the left wing beam 31 and the right wing beam 32. By setting the crossbeam 50 to the first auxiliary beam 61 and the second auxiliary beam 62, and the first auxiliary beam 61 and the second auxiliary beam 62 to intersect with the upper sound beam 21 and the left wing beam 31 and the right wing beam 32, the overall strength is ensured.
[0041] Furthermore, the instrument also includes a tone hole reinforcing plate 70. The tone hole reinforcing plate 70 has through holes that coincide with the tone holes 11. The upper edge of the tone hole reinforcing plate 70 is connected to the crossbeam 50, the lower edge is connected to the upper sound beam 21, the left edge is connected to the first auxiliary beam 61, and the right edge is connected to the second auxiliary beam 62. By placing the tone hole reinforcing plate 70 within the area surrounded by the crossbeam 50, the upper sound beam 21, the first auxiliary beam 61, and the second auxiliary beam 62, the vibrations and stresses experienced by the tone holes 11 during instrument playing are dispersed, reducing fatigue at the edges of the tone holes 11 and preventing cracks or other damage.
[0042] Example 2:
[0043] This embodiment provides a guitar based on embodiment 1, including a body, neck, tuner, and strings; wherein the body includes a back plate, side plates, and a guitar soundboard 10 with an arc-shaped sound bar as described in embodiment 1.
[0044] The guitar in this embodiment significantly improves sound quality and volume by providing arc-shaped upper and lower sound beams 21 and 22 on the back of the guitar soundboard 10, in conjunction with arc-shaped left and right wing beams 31 and 32. This ensures structural stability while maximizing acoustic performance. The clever arrangement of the sound beams and wing beams optimizes resonance and enhances overall sound performance. The ends of the arc-shaped upper and lower sound beams 21 and 22, and the left and right wing beams 31 and 32 extend to the edge of the soundboard 10, facilitating tooling and positioning connections, making it more suitable for mass production and ensuring consistent product quality. Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape, proportions, installation arrangement, material use, color, orientation, etc. of the various elements) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.
[0045] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
