Description

Technical Field

[0001] The utility model relates to the technical field of electric guitars, and particularly relates to a string bridge. Background Art

[0002] An electric guitar is a modern musical instrument. Compared with traditional acoustic guitars, it is different in design and sound generation mechanism. Electric guitars mainly amplify sound through electromagnetic principles. Existing string bridges mostly adopt two-point and six-point fixed string bridges. The two-point type uses the cooperation of a string pulling plate and two fixed columns to achieve the swinging tightness of the string pulling plate to realize the tremolo effect. The two-point string bridge has high requirements for the strength of the string pulling plate, and the matching position with the column is prone to wear, resulting in short part life and reduced sensitivity of the tremolo effect. Moreover, the back of the string pulling contacts the guitar body, and the tremolo amplitude is limited. Therefore, the inventor analyzed and summarized the working defects of the traditional electric guitar tremolo system according to the working principle and purpose of the electric guitar string bridge, continuously upgraded and transformed it, and after multiple tests, finally developed a new tremolo system, which realizes convenient installation, higher tremolo sensitivity, and more stable component structure. The applicant has applied for a patent, "A String Bridge of an Electric Guitar" with the application number "2024214241036". However, when using the tremolo bar in this string bridge, since the tremolo bar is not parallel to the strings, in order for the guitarist to press the tremolo bar, the guitarist needs to move the palm downwards and deflect the angle to adapt to the position of the tremolo bar before pressing to produce a tremolo, which makes it impossible for the guitarist to catch the rhythm point in time for the tremolo, resulting in untimely tremolo. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a string bridge to solve the problem that the current tremolo bar is not convenient for the guitarist to switch from the playing state to the state of pressing the tremolo bar in time, resulting in untimely tremolo.

[0004] A string bridge in this solution includes a base, a string pulling plate, six sliders, a tremolo bar, and a fixing strip arranged from bottom to top. The tremolo bar includes a connecting rod and a pressing rod, and the pressing rod is bent in the middle, and the bending angle is 140° - 170°.

[0005] Working principle and beneficial effects of this solution: The hand-held part of the existing vibrato bar is straight. When the vibrato bar is in use, the end of the pressing rod is close to the body guard and is located below the strings when playing the guitar. The straight hand-held part forms a certain inclination angle with the direction of the strings. Therefore, when the palm presses on the straight vibrato bar, the palm that needs to pluck the strings has to move downward, and the posture of the palm when playing the guitar needs to be inclined at a certain angle to fully press the vibrato bar, so as to achieve vibrato. The process of the palm moving downward and deflecting the angle to adapt to the vibrato bar takes time, and the guitarist cannot catch the rhythm point immediately. In this solution, the pressing rod is set in a bent shape so that after the connecting rod is connected to the base, the bent position of the pressing rod can be kept as parallel as possible to the strings, enabling the guitarist to directly move the palm downward to press the pressing rod after plucking the strings, quickly achieving vibrato. Using the vibrato bar in this solution can reduce the time for the palm to rotate and deflect the angle to adapt to the pressing rod, thus enabling the guitarist to quickly perform vibrato.

[0006] Further, the connecting rod is connected with an installation base through a locking nut. The installation base is connected between the bridge plate and the base, and the installation base connects the vibrato bar, the bridge plate and the base. The bridge is suspended in the designed cavity of the guitar body. By pressing the vibrato bar, the bridge plate rotates around the fixed strip to achieve a sensitive vibrato effect. Such a setting enables the upper part of the bridge to quickly approach the strings and hold them when the vibrato bar is pressed.

[0007] Further, the fixed strip and the bridge plate are connected through an arc-shaped concave-convex snap fit. Since the fixed strip and the bridge plate are in surface contact, the bridge plate and the fixed strip are not easily worn, which can improve the product life.

[0008] Further, the base is trapezoidal in reverse, and three notches are provided at the bottom of the base. A copper wheel is fixed in the notch through a copper wheel shaft and a tension spring. The base is set as trapezoidal in reverse, increasing the thickness and slope. When the tension spring is pulled, the tension of the tension spring can be controlled more stably.

[0009] Further, a plurality of long strip-shaped grooves are arranged side by side on the bridge plate. The slider is provided with a through groove and two small holes. An internal hexagonal socket head cap screw is slidably connected in the through groove. The internal hexagonal socket head cap screw passes through the bridge plate and is threadedly connected with the base. The small holes are connected with the grooves through internal hexagonal flat end set screws. In the existing connection of the base, the bridge plate and the slider, only the hexagonal countersunk head screws are directly assembled, but in this way, the position of the slider cannot be adjusted horizontally. Therefore, two small holes and grooves are provided. After adjusting the position of the slider, the internal hexagonal socket head cap screw is passed through the through groove and the bridge plate, and the internal hexagonal socket head cap screw is tightened to connect the internal hexagonal socket head cap screw with the base, and the small holes and the grooves are connected through the hexagonal flat end set screws, so that the position of the slider can be horizontally moved.

[0014] The embodiment is basically as shown in the attached Figure 1 and Figure 2 : A string bridge, comprising a base 7, a string pulling plate 6, six sliders 5, a tremolo bar and a fixing strip 8 arranged from bottom to top; the fixing strip 8 and the string pulling plate 6 are connected by a circular arc-shaped concave-convex snap fit; the tremolo bar comprises a connecting rod 2 and a pressing rod 1, the pressing rod 1 is bent in the middle, and the bending angle is 160°, the connecting rod 2 is connected with a mounting base 4 through a locking nut 3, the mounting base 4 is connected between the string pulling plate 6 and the base 7, the mounting base 4 connects the tremolo bar, the string pulling plate 6 and the base 7, and the string pulling plate 6 and the base 7 are connected by hexagon socket countersunk head screws 11; a plurality of long strip-shaped grooves 17 are arranged side by side on the string pulling plate 6, the slider 5 is provided with a through groove 18 and two small holes, a hexagon socket head cap screw 9 is slidably connected in the through groove 18, the hexagon socket head cap screw 9 passes through the string pulling plate 6 and is threadedly connected with the base 7, and the small holes are assembled with the grooves 17 through hexagon socket flat end set screws 10; the base 7 is an inverted trapezoid, and three notches 16 are arranged at the bottom of the base 7, and a tension spring is fixed in the notches 16 through a copper wheel shaft 13 and a tension spring fixing copper wheel 14.

[0015] The hand-held part of the existing vibrato bar is straight. When the vibrato bar is in use, the end of the pressing rod 1 is close to the body guard and is located below the strings when playing the guitar. The straight hand-held part forms a certain inclination angle with the direction of the strings. Therefore, when the palm presses on the straight vibrato bar, the palm that needs to pluck the strings has to move downward, and at the same time, the posture of the palm when playing the guitar needs to be inclined at a certain angle to fully press the vibrato bar, so as to achieve vibrato. The process of the palm moving downward and deflecting the angle to adapt to the vibrato bar takes time, and the guitarist cannot catch the rhythm point immediately. In the implementation of this solution, the fixing strip 8 is fixed on the body guard by the cross recessed countersunk head self-tapping screw 12. The pressing rod 1 is set in a bent shape, so that after the connecting rod 2 is connected to the base 7, the bent position of the pressing rod 1 can be kept as parallel as possible to the strings, enabling the guitarist to directly move the palm downward to press the pressing rod 1 after plucking the strings, quickly achieving vibrato. Using the vibrato bar in this solution can reduce the time for rotating the palm and deflecting the angle to adapt to the pressing rod 1, thus enabling the guitarist to quickly perform vibrato. During use, if it is necessary to adjust the horizontal position of the slider 5 on the string puller 6, after placing the slider 5 in position, pass the hexagon socket head cap screw 9 through the through slot 18 and the string puller 6, tighten the hexagon socket head cap screw 9 so that the hexagon socket head cap screw 9 is connected to the base 7, and connect the small hole and the groove 17 with the hexagon flat end set screw, then the horizontal position of the slider 5 can be moved.
