Description

Technical Field

[0001] This utility model belongs to the field of violin fingerboard technology, specifically relating to a multi-layer composite violin fingerboard. Background Technology

[0002] Multi-layer composite violin fingerboards are an innovative musical instrument component. They are defined as replacing traditional ebony fingerboards by using a layered structure of different materials. The principle is based on the mechanical and acoustic properties of composite materials, achieving functional optimization through the combination of a main body and laminated veneers. The main body uses acoustically superior woods such as spruce or composite materials, while the top and sides are laminated with ebony or alternative materials. This retains the traditional feel and appearance while reducing reliance on scarce ebony. Multi-layer composite violin fingerboards improve acoustic quality and optimize vibration transmission efficiency through material synergy, while simultaneously reducing costs and enhancing durability.

[0003] Existing multi-layer composite violin fingerboards typically combine a main body blank with a laminated sheet to achieve functional optimization. However, the thickness of these fingerboards is often fixed. This fixed thickness design makes it difficult for the fingerboard to fully adapt to the unique touch requirements of different players. Since each player's finger strength, fingering habits, and playing style are different, a fixed-thickness fingerboard cannot flexibly meet these differences, which further affects the violin's tone performance. Tone, as one of the key elements of violin playing, is greatly reduced due to an unsuitable fingerboard thickness, thus making multi-layer composite violin fingerboards less suitable for practical use. Utility Model Content

[0004] This invention proposes a multi-layer composite violin fingerboard to address the problem of difficulty in flexibly adjusting the thickness of existing multi-layer composite violin fingerboards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite violin fingerboard, comprising:

Example 2

[0036] Please see Figure 1-4 This utility model provides a multi-layer composite violin fingerboard, comprising:

[0037] Finger plate body 1 and bonding sheet body 2;

[0038] Mounting plate 3 is set at the bottom of the bonding sheet body 2 and at the top of the finger plate body 1. The finger plate body 1, the bonding sheet body 2 and the mounting plate 3 are all arc-shaped.

[0039] The snap-fit ​​plate 4 is set at the bottom of the bonding sheet body 2. The snap-fit ​​plate 4 is T-shaped. The upper end of the mounting plate 3 is provided with a snap-fit ​​groove that matches the snap-fit ​​plate 4.

[0041] Specifically, such as Figure 2 and Figure 4 As shown, multiple locking holes are provided on both sides of the locking slot, and a matching locking rod 12 is slidably connected in each of the multiple locking holes. Multiple locking slots 13 that are compatible with the locking rod 12 are provided on both sides of the locking plate 4.

[0042] Through its design, when multiple locking rods 12 enter or disengage from multiple locking slots 13 respectively, the position of the snap-fit ​​plate 4 can be conveniently limited and released, thereby making it convenient to install or disassemble the bonding sheet body 2, which is convenient for subsequent maintenance or replacement.

[0043] Specifically, such as Figure 2 and Figure 4 As shown, the multiple locking levers 12 and multiple locking slots 13 are all arranged in an arc shape, which makes it easier for the multiple locking levers 12 to enter or disengage from the multiple locking slots 13.

[0044] Specifically, such as Figure 2 and Figure 4 As shown, each of the multiple locking rods 12 is provided with a limiting spring 14 at one end, and the other end of the multiple limiting springs 14 is respectively provided on one side of the multiple snap-fit ​​holes.

[0045] See Figure 1-4 When using a multi-layer composite violin fingerboard, its thickness needs to be adjusted. First, the fixing nut 7 needs to be rotated, which will drive the threaded rod 6 to rotate. The threaded rod 6 will drive the positioning plate 5 to move up and down, and the positioning plate 5 will drive the mounting plate 3 and the bonding sheet body 2 to move up and down. This allows the thickness of the multi-layer composite violin fingerboard to be adjusted. When it is necessary to install or remove the bonding sheet body 2, the bonding sheet body 2 and the snap-fit ​​plate 4 need to be pushed so that the multiple locking rods 12 disengage from the multiple locking slots 13. This allows for convenient removal of the bonding sheet body 2, making the multi-layer composite violin fingerboard more practical.
