Description

Technical Field

[0001] The utility model relates to the technical field of electric guitars, in particular to a string bridge of an electric guitar. Background Art

[0002] The electric guitar is a modern musical instrument. Compared to the traditional acoustic guitar, it differs in design and sound production mechanism. The electric guitar primarily amplifies sound through electromagnetic principles. However, the tremolo system of current electric guitars is not sensitive enough. Existing bridges mostly use two-point or six-point fixed bridges. The two-point bridge uses a tailpiece that cooperates with two fixed posts to achieve a tight swinging of the tailpiece, thus producing a vibrato effect. The two-point bridge requires high strength for the tailpiece, and the position where it mates with the posts is prone to wear, resulting in a short component life and reduced vibrato sensitivity. Furthermore, the back of the string contacts the guitar body, limiting the vibrato amplitude. Therefore, based on the working principle and purpose of the electric guitar, the inventor analyzed and summarized the working defects of the traditional electric guitar tremolo system, continuously upgraded and modified it, and after conducting multiple experiments, he finally developed a new tremolo system that not only has higher vibrato sensitivity, but also is easy to install and has a more stable component structure. Utility Model Content

[0003] The utility model aims to provide a string bridge for an electric guitar, so as to solve the problem that the tremolo system of the existing electric guitar has a short service life and easily leads to a decrease in tremolo sensitivity.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a bridge for an electric guitar, comprising a base, a tailpiece, six sliders and a tremolo rod arranged from bottom to top;

[0005] It also includes a fixing strip, which is provided with a vertical downward through hole, and the through hole is used to cooperate with screws to install the fixing strip on the piano body. A horizontal arc-shaped groove is provided on the side wall of the fixing strip facing the tailpiece. A wing plate extends horizontally on the tailpiece, and the end of the wing plate is an arc-shaped convex surface, which is used to be inserted into the arc-shaped groove and used in conjunction with the arc-shaped groove.

[0006] Furthermore, the through hole provided on the fixing strip is in the shape of an elongated strip.

[0007] Furthermore, both ends of the through hole are arc-shaped curved surfaces.

[0008] Furthermore, there are two arc-shaped grooves, which are located at the same horizontal height. A positioning hole is provided on the fixing strip, and the positioning hole is located between the two arc-shaped grooves.

[0009] Furthermore, a clearance opening is provided in the middle of the convex surface, the width of which is greater than or equal to the distance between the two arc-shaped grooves, and a positioning pin is fixedly connected in the clearance opening, which is used to be inserted into the positioning hole to achieve precise positioning of the string plate and the fixed strip.

[0010] Working principle and beneficial effects of the utility model:

[0011] During installation, two screws pass through the through holes to fix the fixing strip on the guitar body. Six sliders are connected to the string plate through socket head cap screws with internal hexagon, and the string plate is fixed on the base. Three spring fixing wheels are fixedly connected to the lower part of the base, and the tremolo bar is assembled on the string plate through a lock nut and a locking sleeve. The fixing strip and the string plate are matched by clamping through an arc-shaped groove and an arc-shaped convex surface designed in an arc shape. The contact surface is an arc surface, and the bottom is pulled by a spring. The entire string bridge is pulled by the strings on its upper part. The string plate is firmly stuck in the arc-shaped groove of the fixing strip. A positioning hole is designed in the middle of the side wall of the fixing strip to enable precise positioning of the string plate. The string bridge is suspended in the designed cavity of the guitar body. By pressing or lifting the tremolo bar, the string plate rotates around the strip to achieve a sensitive tremolo effect.

[0012] 1. In this solution, since the arc-shaped convex surface of the wing plate of the string plate and the arc-shaped groove of the fixing strip are in surface contact, the force on the contact surface is dispersed on the contact surface, thus reducing the force per unit area. Therefore, it is not easy to wear between the string plate and the fixing strip, and the service life of the string bridge is improved.

[0013] 2. Since the string bridge is suspended, the upper part is pulled by the strings and the lower part is pulled by the spring. When pressing or lifting the tremolo bar, the tightness of the strings moves with the movement of the string bridge, achieving a sensitive tremolo effect.

[0014] 3. Precise positioning of the string plate and the fixing strip can be achieved through the positioning hole and the positioning pin. At the same time, the arc-shaped convex surface and the arc-shaped groove are matched and clamped, making the installation method simple and fast. Description of the drawings
