Instrument damping bar

Abstract

This utility model discloses a musical instrument damping strip, comprising a soft rubber strip with multiple rows of damping posts on its bottom surface. These rows are spaced apart along the length of the rubber strip, and each row includes multiple damping posts spaced apart along the width of the rubber strip. A string-catching groove is formed between adjacent damping posts in each row to accommodate the strings. This musical instrument damping strip, by setting multiple rows and columns of damping posts on the bottom surface of the soft rubber strip, forms a dot-matrix string-catching structure. This dot-matrix string-catching structure eliminates the need for precise alignment and insertion of each string during installation. Users simply place the entire damping strip roughly on the strings, and the strings will naturally fall into the string-catching grooves formed between adjacent damping posts in a row due to their own tension and gravity. This greatly simplifies the installation and disassembly process, saves considerable time, and significantly reduces the difficulty of operation, making it more user-friendly for beginners and children.

Description

Technical Field

[0001] This utility model relates to musical instruments, and more particularly to a damping strip for musical instruments. Background Technology

[0002] Stringed instruments, such as the guzheng and guqin, are widely loved for their unique timbre and expressiveness. However, in the initial learning or daily practice stages, performers typically need to engage in long hours of intensive, repetitive training. During this process, the instruments produce a relatively loud volume, inevitably causing noise pollution to the performer's family members or surrounding neighbors. This is particularly prominent in densely populated modern urban environments such as apartment buildings, limiting the performer's practice time and freedom.

[0003] To address this issue, a damping strip for stringed instruments is disclosed in the prior art. This damping strip is typically a strip of soft rubber with a series of string-catching grooves along its length corresponding to the number of strings. In use, the player needs to precisely insert each string one by one into its corresponding groove. The contact between the soft rubber strip and the string limits the amplitude of string vibration, thereby reducing the volume.

[0004] However, this type of damping bar has significant drawbacks. First, the installation and removal process is extremely cumbersome and time-consuming. Especially for instruments like the guzheng with a large number of strings, users need to spend a lot of time and effort aligning and inserting each string individually, which is inconvenient. Second, this delicate operation is quite difficult for beginners or children. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in the related art. Therefore, the purpose of this invention is to provide a damping strip for musical instruments.

[0006] To achieve the above objectives, the musical instrument damping strip according to an embodiment of the present invention includes:

[0007] A soft rubber strip, the bottom surface of which is provided with multiple rows of damping posts, the multiple rows of damping posts being spaced apart in the width direction of the soft rubber strip, each row of damping posts including multiple damping posts spaced apart in the length direction of the soft rubber strip, and a string-catching groove being formed between two adjacent damping posts in each row, the string-catching groove being used to accommodate strings.

[0008] According to the instrument damping strip provided in this embodiment, a dot-matrix string-locking structure is formed by setting multiple rows and columns of damping posts on the bottom surface of the soft rubber strip. This dot-matrix string-locking structure eliminates the need for precise alignment and insertion of each string during installation. Users simply place the entire damping strip roughly on the string, and the string will naturally fall into the string-locking groove formed between two adjacent damping posts in a row due to its own tension and gravity. This greatly simplifies the installation and disassembly process, saves a significant amount of time, and significantly reduces the difficulty of operation, making it more user-friendly for beginners and children.

[0009] In addition, the instrument damping strip according to the above embodiments of this utility model may also have the following additional technical features:

[0010] According to one embodiment of the present invention, each of the noise-reducing columns in different rows can form multiple rows of noise-reducing columns, which are spaced apart along the length of the soft rubber strip, and each row of noise-reducing columns is arranged obliquely from one side to the other side of the width direction of the soft rubber strip.

[0011] According to one embodiment of the present invention, the noise-reducing column is formed as a conical column.

[0012] According to one embodiment of the present invention, the two ends of the soft rubber strip are respectively provided with limiting protrusions, the limiting protrusions are in the same direction as the pitch-damping column, and the two limiting protrusions are respectively used to be locked on the outside of the two outermost strings of the musical instrument.

[0013] According to one embodiment of the present invention, at least one end of the soft rubber strip is provided with a gripping portion.

[0014] According to one embodiment of the present invention, the gripping part is provided with a hanging hole.

[0015] According to one embodiment of the present invention, the noise-reducing columns in two adjacent rows are staggered so that the line connecting three adjacent noise-reducing columns in two adjacent rows forms an isosceles triangle.

[0016] According to one embodiment of the present invention, the soft rubber strip is made of one of the following materials: silicone, TPE, TPU, EVA, and rubber.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0038] The instrument damping strip of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 6 As shown, the instrument damping strip provided according to an embodiment of the present invention includes a soft rubber strip 10, and the bottom surface of the soft rubber strip 10 is provided with multiple rows of damping columns 101. Preferably, the damping columns 101 and the soft rubber strip 10 are integrally formed to ensure structural integrity and ease of processing.

[0040] Multiple rows of sound-absorbing columns 101 are spaced apart in the width direction of the soft rubber strip 10. Each row of sound-absorbing columns 101 includes multiple sound-absorbing columns 101 spaced apart in the length direction of the soft rubber strip 10. In this way, an integral dot matrix of sound-absorbing columns 101 is formed on the bottom surface of the soft rubber strip 10.

[0041] In each row of damping posts 101, a string-catching groove is formed between two adjacent damping posts 101, which is used to accommodate the strings. That is, the width of the string-catching groove is designed to be greater than the diameter of the strings, so that the strings can be restrained by the damping posts 101 on both sides after falling in.

[0042] Preferably, the soft rubber strip 10 can be made of a material with good elasticity, such as silicone, TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane), EVA (ethylene-vinyl acetate copolymer), rubber, etc. These materials can ensure that they do not damage the strings when in contact with them, and can effectively absorb the vibration energy of the strings. The damping post 101 can be cylindrical, square, or, to better guide the strings to slide in, its top can be designed with rounded corners or an arc surface.

[0043] When the user needs to dampen the instrument, they simply place the damping strip roughly horizontally above the strings and gently press down or let it fall using its own weight. Due to the tension of the strings and the multiple landing points provided by the dot-matrix arrangement of the damping posts 101, each string easily and automatically slides down and embeds itself into a suitable string slot. Once the string is stably accommodated in the string slot, the vibrations generated during playing are effectively transmitted to the entire soft rubber strip 10 body through the damping posts 101 on both sides, and absorbed and attenuated by the damping properties of the soft material, thus significantly suppressing the amplitude and duration of string vibration and reducing the volume. Disassembly is equally convenient; simply lift the entire damping strip from the strings.

[0044] According to the instrument damping strip provided in this embodiment, a dot-matrix string-locking structure is formed by setting multiple rows and columns of damping posts 101 on the bottom surface of the soft rubber strip 10. With this dot-matrix string-locking structure, users no longer need to precisely align and insert each string during installation. They only need to roughly place the entire damping strip on the string, and the string will naturally fall into the string-locking groove formed between two adjacent damping posts 101 in a row due to its own tension and gravity. This greatly simplifies the installation and disassembly steps, saves a lot of time, and significantly reduces the difficulty of operation, making it more user-friendly for beginners and children.

[0045] Reference Figure 6 As shown, in some embodiments of this utility model, the various noise-dampening columns 101 in different rows can form multiple rows of noise-dampening columns 101. These multiple rows of noise-dampening columns 101 are spaced apart along the length of the soft rubber strip 10, and each row of noise-dampening columns 101 is arranged obliquely from one side to the other in the width direction of the soft rubber strip 10. This oblique arrangement means that each row of noise-dampening columns 101 forms a preset angle with the length direction of the soft rubber strip 10; preferably, this angle is 30 to 45°. All rows of noise-dampening columns 101 can be inclined at the same angle and direction, forming a set of parallel diagonal lines.

[0046] With this tilted layout, the overall arrangement of the damping posts 101 can still be considered as a dot matrix, with rows of tilted damping posts 101. When the user places this damping strip on the strings of a musical instrument (such as a guzheng), since the strings are usually arranged parallel or nearly parallel along the length of the instrument, and each row of damping posts 101 is tilted, when the entire damping strip is slightly slid along the string direction (i.e., the length direction of the soft rubber strip 10), the lateral position of each string relative to its lower string slot will undergo continuous, minute changes. Therefore, even if some strings do not fall accurately into the string slots during initial placement, the user does not need to lift and reposition the damping strip. Simply adjusting and sliding it back and forth along the string direction will always find a precise position, ensuring that all strings are aligned and fall into their respective string slots without omission. This greatly enhances the compatibility of damping strips with instruments of different string spacings and the tolerance for errors during installation. It also provides users with an extremely simple and intuitive means of fine-tuning; with a simple release and slide, all strings can be locked in place, ensuring a reliable damping effect. Furthermore, this simplifies the installation process, reduces the requirement for precise alignment by the user, greatly improves the user experience, and makes the installation process faster and more efficient.

[0047] Reference Figures 3 to 4 As shown, in one embodiment of this utility model, the sound damping column 101 is formed as a tapered column with an incline. "Tapered" means that the cross-sectional area of ​​each sound damping column 101 gradually decreases from its root, which is connected to the main body of the soft rubber strip 10, to its top, which is far from the root, and the whole presents a cone or pyramidal shape.

[0048] This tapered structure, narrower at the top and wider at the bottom, gives the damping post 101 a tapered outer surface. When damping bars with this structure are installed, their self-alignment and automatic placement capabilities are significantly enhanced. During the placement of the damping bar above the strings, even if the initial placement point of a string is off and fails to align directly with the center of the string slot, it is highly likely to contact the tapered outer surface of one of the tapered damping posts 101. The tapered outer surface of the damping post 101 generates a guiding force that slides the string downwards and towards the center of the slot. Under this guidance, the string slides very smoothly towards the base of the damping post 101 and finally falls into the string slot, the entire process requiring almost no manual intervention.

[0049] This embodiment designs the damping post 101 as a conical post, providing an effective physical guiding structure for each string slot. This structure actively captures and guides the strings, greatly improving the success rate and speed of the strings falling into the string slots, and significantly enhancing the self-alignment capability of the damping strip. It reduces the possibility of strings getting stuck at the top of the damping post 101 due to inaccurate placement, making the installation process smoother, faster, and more reliable, thereby further optimizing the user experience.

[0050] Reference Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the adjacent rows of sound-absorbing columns 101 are staggered so that the line connecting three adjacent sound-absorbing columns 101 in the adjacent rows forms an isosceles triangle.

[0051] Because the damping posts 101 are arranged in isosceles triangles, each damping post 101 is surrounded by six adjacent damping posts 101 (except for the edge positions), forming six string slots. This layout makes the string slots more evenly and densely distributed on the surface of the soft rubber strip 10, reducing possible dead zones or sparse areas. For the strings, no matter where they fall on the soft rubber strip 10, they can find a suitable string slot within a very short distance, greatly improving the convenience and success rate of installation.

[0052] Reference Figure 2 , Figures 4 to 5 As shown, in one embodiment of this utility model, the two ends of the soft rubber strip 10 are respectively provided with limiting protrusions 102. The limiting protrusions 102 and the damping post 101 protrude in the same direction, that is, both extend vertically downward from the bottom surface of the soft rubber strip 10. The two limiting protrusions 102 are respectively used to lock onto the outer sides of the two outermost strings of the musical instrument. Preferably, the height of the limiting protrusions 102 extending from the bottom surface of the soft rubber strip 10 can be equal to or slightly greater than the height of the damping post 101 to ensure reliable contact with the strings. The distance between the inner sidewalls of the two limiting protrusions 102 is set to be slightly greater than the total width between the two outermost strings of the target musical instrument (such as a guzheng).

[0053] During installation, the user places the damping strip on the strings and adjusts its lateral position so that one end of the limiting protrusion 102 is located outside the first string of the instrument, while the other end is located outside the last string. In this way, the entire string assembly is framed between the two limiting protrusions 102. After installation, these two limiting protrusions 102 serve a positioning function. This positioning effectively prevents the damping strip from shifting or falling off due to vibration or accidental contact during playing, greatly improving the stability and reliability of the installation.

[0054] Reference Figures 1 to 2 and Figure 4 As shown, in some embodiments of this utility model, at least one end of the soft rubber strip 10 is provided with a gripping portion 103. The gripping portion 103 is integrally formed with the soft rubber strip 10 or fixed by connection, and is located at one or both ends of the soft rubber strip 10 along its length. The shape and size of the gripping portion 103 are matched to the natural gripping posture of an adult's fingers.

[0055] By providing a grip portion 103 at at least one end of the soft rubber strip 10, the ease of operation and user experience of the noise reduction strip are significantly improved. The grip portion 103 provides a point of contact for the user, making it easier and simpler to pick up, place, adjust, and remove the noise reduction strip.

[0056] Preferably, the grip portion 103 is provided with a hanging hole H10, so that when not in use, it can be hung on other carriers through the hanging hole H10, making it convenient to use and store.
