Description

Technical Field

[0001] This utility model relates to the field of musical instrument technology, specifically to a novel stringed instrument. Background Technology

[0002] Traditional stringed instruments such as Figure 4 As shown, the front, back, and side panels form a single resonating chamber. Both the front and back panels have a bulging shape, higher in the middle and lower at the edges. They typically have four strings—high, mid, and low—distributed on a curved fingerboard. The fingerboard allows players to adjust the position of the fingers to produce different notes. The taut strings transmit their vibrations to the front panel via the bridge, and the vibrations produce sound in the resonating chamber formed by the front and back panels. However, this traditional stringed instrument has some technical drawbacks. First, the bow is pulled laterally, and the excited string vibrations are primarily lateral. When converted into force pressing against the panel, some loss occurs, affecting sound transmission efficiency. Second, the vibration is first transmitted to the top panel via the bridge, and then to the back panel via the internal soundpost. This transmission method is greatly affected by the soundpost installation process, potentially leading to unstable sound quality. Even with proper soundpost installation, the quality of sound transmitted to the back panel is limited. Historically, musical instruments have been considered to transmit sound only through the top panel.

[0003] Furthermore, the relatively fixed resonator structure of traditional stringed instruments limits the diversity and richness of their sound. Additionally, the complex manufacturing process of traditional stringed instruments, with its high requirements for materials and craftsmanship, increases production costs and difficulty. To address these issues, existing technologies urgently need improvement. Summary of the Invention

[0004] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a novel stringed instrument that offers advantages such as improved sound transmission efficiency, enhanced sound quality stability, increased sound diversity and richness, and simplified manufacturing process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel stringed instrument, comprising a left panel, a right panel, and side panels. The left and right panels each have an indentation in the middle. The side panels are semi-cylindrical. The left, right, and side panels form an open resonating chamber. A crossbeam is fixed between the left and right panels near the indentation, and a bridge is mounted on the crossbeam. A sealing plate is attached to one side of the left and right panels near the bridge. The sealing plate has a fingerboard extending out of the left and right panels at the center of its width. Strings are mounted between the bridge and the fingerboard, and the strings are matched with a bow.

[0006] Furthermore, the size of the recessed opening meets the lateral pulling range of the bow.

[0007] This utility model provides a technical solution for another novel stringed instrument. The novel stringed instrument includes a left panel, a right panel, and side panels. The left and right panels are flat, and the side panels are semi-cylindrical. The left, right, and side panels form an open resonating cavity. A crossbeam is fixed inside the resonating cavity between the left and right panels, and a bridge is provided on the crossbeam. A sealing plate is attached to one side of the left and right panels near the bridge. A fingerboard is provided at the center of the width of the sealing plate, extending outside the left and right panels. Strings are provided between the bridge and the fingerboard, and the strings are matched with a bow.

[0008] When in use, this invention transmits the lateral vibration of the bow and the vibration of the strings through the bridge to the connecting beam, and simultaneously to the left and right soundboards, resulting in a richer and more varied tone. This changes the common practice in traditional musical instruments where sound is transmitted through only one soundboard, which is the biggest difference from existing instruments. In addition, the lateral vibration excitation brought about by the lateral pull of the bow can be better transmitted to the left and right soundboards. The concave openings in the middle of the left and right soundboards make the distance between them smaller, which is convenient for bowing, and also creates a more curved resonance cavity, forming a rich tone.

[0009] The beneficial effects of this utility model are: it changes the structure and appearance of traditional stringed instruments, presenting a brand-new look, with a more reasonable structural design. This structural design improves the transmission method of string vibration and increases sound transmission efficiency; the open resonance cavity and concave design increase the diversity and richness of sound; the overall structure simplifies the manufacturing process, and has the advantages of improving sound transmission efficiency, improving sound quality stability, increasing sound diversity and richness, and simplifying the manufacturing process.

[0016] See appendix Figure 1-2 This is one embodiment of the present invention, which discloses a novel stringed instrument, including a left panel 3, a right panel 2, and a side panel 1. The left panel 3 and the right panel 2 are both provided with an indentation 8 in the middle. The side panel 1 is semi-cylindrical. The left panel 3, the right panel 2, and the side panel 1 form an open resonating cavity 9. A crossbeam 4 is fixed between the left panel 3 and the right panel 2 near the indentation 8. A bridge 7 is provided on the crossbeam 4. A sealing plate 6 is attached to one side of the left panel 3 and the right panel 2 near the bridge 7. The sealing plate 6 has a fingerboard 5 extending out of the left panel 3 and the right panel 2 at the center of its width. A string is provided between the bridge 7 and the fingerboard 5. The string is matched with a bow.

[0017] This invention addresses the problem in traditional stringed instruments where the string vibrations caused by the lateral pulling of the bow are predominantly lateral, and the significant impact of the soundpost installation process on the transmission of vibrations from the bridge 7 to the top plate and then to the back plate. Traditional stringed instruments suffer from low vibration transmission efficiency due to the lateral pulling of the bow and the significant influence of the soundpost installation process, thus limiting their sound quality and performance.

[0018] This invention solves the problem of low vibration transmission efficiency in traditional stringed instruments caused by the lateral pulling of the bow, through an open resonance cavity design consisting of a left panel 3, a right panel 2, and a side panel 1. The recessed opening 8 in the middle of the left panel 3 and right panel 2 makes the lateral pulling of the bow smoother, reducing energy loss during vibration transmission. Furthermore, the semi-cylindrical side panel 1 and the open resonance cavity design change the vibration transmission path of traditional stringed instruments, reducing reliance on soundpost mounting techniques. The bridge 7 design on the crossbeam 4 allows string vibrations to be transmitted more directly to the resonance cavity, improving sound quality. The fingerboard 5 extending from the endplate 6 facilitates the player's pressing of the strings to play different notes. Therefore, this invention provides an effective solution to the technical problems of traditional stringed instruments.

[0019] In this embodiment, each component has unique technical features during the study. The recessed area 8 refers to the recessed portion in the middle of the left and right panel 3 and 2, where the bow can be pulled laterally. The semi-cylindrical side panel 1 refers to the semi-circular structure of the side panel 1, which, together with the left and right panel 3 and 2, forms an open resonating chamber. The crossbeam 4 is a structure fixed between the left and right panel 3 and 2, and the bridge 7 is mounted on the crossbeam 4 to support the strings. The fingerboard 5 is a structure installed at the center of the width of the endplate 6, extending beyond the left and right panel 2, and is used to press the strings during playing.

[0020] In this embodiment, the size of the recess 8 meets the requirements of the bow's lateral pulling range. The recess 8 in the middle of the left and right panels results in a small central distance, facilitating bowing and thus improving the flexibility and smoothness of playing.

[0021] See appendix Figure 3 This is another embodiment of the present invention, which discloses another novel stringed instrument, including a left panel 3, a right panel 2, and a side panel 1. The left panel 3 and the right panel 2 are flat, and the side panel 1 is semi-cylindrical. The left panel 3, the right panel 2, and the side panel 1 form an open resonating cavity. A crossbeam is fixed between the left panel 3 and the right panel 2 inside the resonating cavity, and a bridge is provided on the crossbeam. A sealing plate is attached to one side of the left panel 3 and the right panel 2 near the bridge. A fingerboard 5 is provided at the center of the width of the sealing plate, extending outside the left panel 3 and the right panel 2. Strings are provided between the bridge and the fingerboard, and the strings are matched with a bow.

[0022] The above embodiment, through its open resonating cavity design consisting of the left panel 3, right panel 2, and side panel 1, solves the problem of low vibration transmission efficiency in traditional stringed instruments caused by the lateral pulling of the bow. Although the left panel 3 and right panel 2 lack an indentation design, the lateral pulling of the bow is still relatively smooth. Furthermore, the semi-cylindrical side panel 1 and the open resonating cavity design alter the vibration transmission path of traditional stringed instruments, reducing reliance on soundpost mounting technology. The bridge design on the crossbeam allows string vibrations to be transmitted more directly to the resonating cavity, improving sound quality. The fingerboard 5 extending from the endplate facilitates the player's pressing of the strings to play different notes. Therefore, this invention provides another effective solution to the technical problems of traditional stringed instruments.

Various modifications and variations can be made to this application by those skilled in the art.
