Description

Technical Field

[0001] This utility model relates to the field of stringed musical instruments, and in particular to a mechanism for quickly adjusting string tension and a stringed musical instrument. Background Technology

[0002] Vibrato, also known as trilling, is the soul of guitar playing. Many string instruments employ vibrato, such as the guitar, where it's an integral part of the instrument. It's typically marked as tr... or ﹋. After playing a note, the fingers rapidly vibrate the string up and down or left and right with a large amplitude, producing a sharp, trilling effect. Vibrato is usually played as a 32nd note. It plays a crucial role in solo playing, making the connections between phrases stronger and the sound more explosive. While vibrato and trilling have similar effects, they differ in their presentation and intensity. Trilling involves a small, even vibration of the string, while vibrato involves a large, rapid vibration. There are three main vibrato techniques: up-down vibrato: after playing a note, the fingers quickly vibrate up and down the string; left-right vibrato: after playing a note, the fingers quickly vibrate left and right the string; electric guitar tremolo: after playing a note or chord, the tremolo arm is shaken rapidly and with large amplitude to produce a strong vibrato effect.

[0003] Currently, the tension of stringed instruments is mainly adjusted one by one by the tuning knobs on the headstock or the bridge at the tail. This method offers high precision but is relatively slow, so the existing technology still needs improvement. Utility Model Content

[0045] This embodiment demonstrates a stringed instrument using an electric guitar as an example:

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 5 , Figure 6 As shown, this utility model provides a stringed instrument, including a stringed instrument body and a rapid string tension adjustment mechanism as described above. The stringed instrument body has a vertically penetrating adjustment cavity 10, and the rapid string tension adjustment mechanism is installed in the adjustment cavity 10. The upper end of the rapid string tension adjustment mechanism is connected to the strings on the front of the stringed instrument body, and the lower end is connected to the back of the stringed instrument body. The stringed instrument shown in this embodiment is an electric guitar. The rapid string tension adjustment mechanism is installed on the electric guitar. Vibrato is achieved by the elastic swinging of the strings, bridge / swing bar, elastic components, and pivot, which drives the bridge / swing bar to swing. The tension of the electric guitar strings can be quickly adjusted by adjusting the adjustment claw.

[0047] Specifically, the string tension quick adjustment mechanism provided by this utility model includes a bridge 21, a bridge plate 22, a swing lever 23, a pivot 24, and an adjusting claw 25. The bridge 21 and the bridge plate 22 are installed on the side where the strings of the stringed instrument are located, and the strings of the stringed instrument are connected to the corresponding bridge 21. The upper part of the swing lever 23 is fixedly connected to the bridge plate 22. The adjusting claw 25 is located on one side of the lower part of the swing lever and is connected to the stringed instrument. An elastic component is provided between the adjusting claw 25 and the lower part of the swing lever 23. The pivot 24 is connected between the stringed instrument and the bridge plate 22 or the swing lever 23. The adjusting claw 25 and the strings have a tendency to pull the bridge plate 22 or the swing lever 23 toward the side where the pivot 24 is located. Furthermore, in the string tension quick adjustment mechanism provided by this utility model, the bridge 21 is mounted on the bridge plate 22, and the bridge plate 22 is provided with a tuning bolt 29, which is threadedly connected to the bridge 21. The string is pulled from the front of the pivot 24 to the rear of the pivot 24 and connects to the bridge 21 at the rear. The bridge 21 and the string are arranged in a one-to-one correspondence, and the tuning bolt 29 is arranged in a one-to-one correspondence with the bridge 21. When the string pulls the bridge 21 forward, the tuning bolt 29 pulls the bridge 21 backward. The screw head of the tuning bolt 29 is locked on the bridge plate 22. By turning the tuning bolt 29, the front and rear position of the bridge 21 can be adjusted, thereby adjusting the pitch of the corresponding string.

[0048] Furthermore, in the string tension quick adjustment mechanism provided by this utility model, the bridge 21 is disposed at the top end of the swing lever 23, the elastic component is connected to the bottom end of the swing lever 23, the bridge 21 is provided with a downward-through string hole 27, and the swing lever 23 is provided with a vertically through hole 28, the through hole 28 and the bridge 21 are respectively provided, the bridge 21 is installed at the top end of the corresponding through hole 28, and the through hole 28 is located below the corresponding string hole 27. Furthermore, in the string tension quick adjustment mechanism provided by this utility model, the elastic component is a spring 36, one end of the spring 36 is connected to the adjusting claw 25, the other end of the spring 36 is connected to the swing lever 23, and the bridge plate 22 is provided with a crank arm mounting position 30 for mounting the crank arm. In this invention, the strings are attached to the bridge 21 and then pass downwards into the string hole 27 and the through hole 28 of the lower swing lever 23, and are fixed at the bottom end of the swing lever 23. The strings are taut, so that the upper part of the swing lever 23 is pulled. In order to maintain balance, the adjusting claw 25 is installed on the back of the stringed instrument. The bottom end of the swing lever 23 is elastically pulled by the elastic component. In this way, the swing lever 23 is pulled in the same direction, so that the bridge plate 22 fixed at the top of the swing lever abuts against the pivot 24. The pivot 24 of this invention is equivalent to a fulcrum of the swing lever 23, while the adjusting cavity 10 is used to accommodate and restrict the swing of the swing lever 23. This invention provides a novel mechanism for quickly adjusting the tension of guitar strings. Through the swing of the swing lever 23, its simple structure and large lever arm enable rapid adjustment of string tension. Moreover, this structure allows for overall tension adjustment at the bottom, which is very convenient. Furthermore, the swing lever 23 can pass through the electric guitar and has sufficient length, making the lever arm relatively large. This helps reduce the pressure on the elastic components, improves their lifespan, and maintains the stability of the string tone and vibrato.

[0049] Furthermore, in the string tension quick adjustment mechanism provided by this utility model, the adjusting claw 25 is connected to the stringed instrument with an adjustable spacing. Further, in the string tension quick adjustment mechanism provided by this utility model, the adjusting claw 25 is equipped with an adjusting bolt 26 for adjusting the spacing, and the adjusting bolt 26 is threadedly connected to the stringed instrument. In this embodiment, the adjusting bolt 26 has an operating hole for wrench operation on its screw head side. The adjusting claw 25 has three claw ends, each connected to one end of a three springs 36, and the other ends of the three springs 36 are fixed to the bottom end of the swing lever 23. The string tension is adjusted by the adjusting claw pulling or loosening the swing lever through an elastic component, rather than by a single swing lever. The adjusting claw can be exposed on the back of the electric guitar. Quick adjustment of string tension can be achieved through the exposed adjusting claw. By turning the screw to adjust the position of the adjusting claw, the elastic component pulls or loosens the swing lever, thereby continuously tightening or loosening the entire string at the other end of the swing lever.

[0050] like Figure 4 As shown, further, in the string tension quick adjustment mechanism provided by this utility model, the pivot frame 24 includes at least a pair of support columns 31, and the bridge plate 22 is provided with a fork 32 on the side where the strings are located. The fork 32 is correspondingly arranged with the support column 31, and the support column 31 is installed in the corresponding fork 32. Further, in the string tension quick adjustment mechanism provided by this utility model, the support column 31 is a funnel-shaped support column 31, and the fork 32 is connected to the waist of the support column 31. The pivot frame 24 of this embodiment is threadedly connected to the stringed instrument. Further, in the string tension quick adjustment mechanism provided by this utility model, the waist of the support column 31 has an upper conical surface 33 and a lower conical surface 34, and the inner side of the fork 32 has an inner conical surface 35, which cooperates with the lower conical surface 34 of the support column 31. This not only facilitates the quick installation and disassembly of the string tension quick adjustment mechanism, but also improves the stability of the swing lever 23 when swinging.

[0051] In summary, this utility model provides a novel mechanism for quickly adjusting the tension of guitar strings. Through the swing of the swing lever, its simple structure and large lever arm enable rapid adjustment of string tension. Furthermore, this structure allows for overall tension adjustment from the bottom, which is very convenient. The swing lever can penetrate the electric guitar, providing sufficient length to make the lever arm relatively large, which helps reduce pressure on the elastic components, improves their lifespan, and maintains the stability of string tone and vibrato.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
