an acoustic guitar

Abstract

The invention discloses an acoustic guitar. The acoustic guitar comprises a guitar body and strings, wherein the guitar body comprises a head, a neck, a resonator and a string lower-end fixing structure; the string lower-end fixing structure comprises a bridge and a lower nut. The acoustic guitar is characterized in that the string lower-end fixing structure further comprises string penetration holes and a string lower-end fixing member; the string penetration holes penetrate through the bridge below the lower nut and a panel of the resonator in an oblique downward manner, and are communicated with the interior of the resonator; the multiple string penetration holes correspond to the strings one to one; the lower ends of the strings penetrate into the resonator through the string penetration holes; the string lower-end fixing member comprises a string fixing portion; the whole string fixing portion is fixedly mounted inside the resonator; the side end, close to the panel of the resonator, of the string fixing portion is a string fixing side end; the string fixing side end is isolated from the inner side face of the panel of the resonator mutually; the end portions of the lower ends of the strings are fixedly limited to the string fixing side end, and the lower ends of the strings can be fixed. The acoustic guitar has the advantages that the panel of the resonator is not prone to deformation and the sounding quality of the guitar can be better ensured accordingly.

Description

technical field [0001] The invention belongs to the field of guitars, in particular to an acoustic guitar. Background technique [0002] The guitar has many advantages such as elegant timbre, easy to learn, beautiful timbre, rich expressiveness, etc. It is one of the main instruments of popular music today. Guitars are divided into acoustic guitars and electric guitars according to different sounding principles. [0003] It can be known from the background technology of CN203276807U patent that the notification number is that the existing acoustic guitar (see the appended figure 1 and figure 2 ) including nut 1, strings 2, saddle 3 (there is an error here, it is actually "lower saddle"), tailpiece 4 (there is an error here, it is actually "the saddle (horse)"), panel 5 , side plate 6, wooden pier 7, piano bridge 3 and tailpiece 4 are fixed, tailpiece 4 is fixed on panel 5, strings 2 are supported by string nut 1 and piano yard 3 and then tensioned with tailpiece 4 Fixed...

AI Technical Summary

Problems solved by technology

[0006] (1) The huge force generated by the tensioned strings 2 acts on the panel through the tailpiece 4, which will cause the deformation of the panels 5 on both sides of the fixed tailpiece 4, with one side protruding and one side sinking, which will easily cause the panels to deform. Cracking, affecting the life of the guitar;

[0007] (2) Since the panel 5 bears the force of tensioning the strings of the tailpiece 4, the panel needs to reach a certain thickness during manufacture to ensure the strength it needs to bear, and the thickening of the panel will directly affect the vibration performance of the guitar. reduce the quality of the guitar;

[0008] (3) Since the wood strength of each panel 5 is not equal, when the panel 5 is subjected to a huge string force, the panel of each guitar will have an unexpected deformation size, which will cause deviations in the sound effect of the guitar and affect the sound of the product quality stability

[0013] Although the above two technical solutions solve the problem of deformation of the panel of the resonance box under the long-term action of string tension, they make the contact between the strings and the saddle 3 (there is an error here, it is actually the "lower string nut") Not tight enough (caused by the small force component of string tension on the saddle), and the saddle is a key component that transmits the vibration of the strings to the panel of the resonance box. When the contact between the strings and the saddle is not tight enough Once firm, it will reduce the volume and quality of the guitar's sound
