Description

Technical Field

[0001] This invention relates to the field of musical instrument technology, specifically to a portable erhu (a two-stringed bowed instrument). Background Technology

[0002] The erhu, as a representative of traditional Chinese bowed string instruments, such as the erhu, gaohu, and jinghu, has a long history, a unique timbre, and is widely used in solo performances, ensembles, and opera accompaniment.

[0003] For example, patent publication number "CN205120132U", entitled "A Portable Variable-Tone Erhu", includes a headstock, bow, soundbox, and tuning mechanism and jack mounted on the bow. The tuning mechanism has an upper tuning pin and a lower tuning pin. The distance between the lower tuning pin and the soundbox is less than 450mm. The headstock is movably connected to the bow. Through the above method, the invention can minimize the overall length of the erhu without affecting its tone and sound quality, without changing the playing method, maintaining its beautiful appearance and good feel, and facilitating disassembly and assembly. It has the advantages of simple structure, convenient disassembly and assembly, beautiful appearance, easy portability, and convenient tuning.

[0004] The foldable or detachable connection between the headstock and neck in the aforementioned patent is prone to loosening after frequent disassembly or long-term use, resulting in a decrease in structural rigidity and affecting the stability of the feel and the accuracy of the pitch during performance. Therefore, a portable erhu is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a portable erhu (a two-stringed bowed instrument) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable erhu, comprising a soundbox and a bow, wherein a telescopic component is fixedly connected to the top of the soundbox, a headstock is fixedly connected to the telescopic end of the telescopic component, a secondary rod is rotatably connected to one end of the bow, and a reinforcing component is installed between the bow and the secondary rod; The telescopic component includes a first cylinder, which is fixedly installed at the top of the instrument body. A first rod is slidably connected inside the first cylinder. The top of the first rod is fixed to the bottom of the headstock. A limiting component is installed between the first rod and the first cylinder to restrict the sliding between the first cylinder and the first rod.

[0007] Preferably, the limiting component includes a first spring, which is fixedly installed inside a first cylindrical rod. A limiting member is fixedly connected to the top end of the first spring. The outer wall of the limiting member is slidably connected to the inner wall of the first cylindrical rod. A positioning hole is provided on the outer wall of the first cylindrical rod.

[0008] Preferably, the reinforcing component includes a movable plate, the outer wall of which is slidably connected to one side of the auxiliary rod, a limiting frame is fixedly connected to one side of the bow, and a positioning component is installed at the top of the movable plate to limit the sliding between the movable plate and the auxiliary rod.

[0009] Preferably, the positioning assembly includes a positioning threaded rod, the outer wall of which is threadedly connected to the inner wall of the moving plate, and a positioning groove adapted to the outer wall of the positioning threaded rod is provided on one side of the auxiliary rod.

[0010] Preferably, a first string is installed between the other end of the bow and one end of the auxiliary rod, and a second string is installed between the soundbox and the headstock.

[0011] Preferably, one end of the bow is fixedly connected to a grip, and the bottom end of the soundbox is fixedly connected to a base.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This portable erhu features a telescopic component fixed to the top of the soundbox, enabling rapid extension and secure locking of the headstock and body. This avoids joint loosening caused by frequent disassembly and ensures stable intonation. Meanwhile, the bow and auxiliary rod are connected and secured by a reinforced assembly with a sliding plate and a positioning threaded rod. This mechanical locking method is more stable and reliable than simple plug-in or folding joints, ensuring the rigidity of the overall structure during performance.

[0013] Meanwhile, the portable design focuses on bow length adjustment (telescopic component) and auxiliary support (secondary rod), while the key sound-producing and resonating component (body) retains its traditional and complete form, thus ensuring the feasibility of playing this portable erhu.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1-3 As shown, the present invention provides a technical solution: a portable erhu, including a soundbox 1 and a bow 2, a telescopic component 3 is fixedly connected to the top of the soundbox 1, a headstock 4 is fixedly connected to the telescopic end of the telescopic component 3, a secondary rod 5 is rotatably connected to one end of the bow 2, and a reinforcing component 7 is installed between the bow 2 and the secondary rod 5. The telescopic component 3 includes a first cylinder 301, which is fixedly installed at the top of the soundbox 1. A first rod 302 is slidably connected inside the first cylinder 301. The top of the first rod 302 is fixed to the bottom of the headstock 4. A limiting component is installed between the first rod 302 and the first cylinder 301 to restrict the sliding between the first cylinder 301 and the first rod 302.

[0018] The limiting component includes a first spring 303, which is fixedly installed inside a first round rod 302. A limiting member 304 is fixedly connected to the top of the first spring 303. The outer wall of the limiting member 304 is slidably connected to the inner wall of the first round rod 302. A positioning hole is provided on the outer wall of the first cylinder 301.

[0019] The reinforcing component 7 includes a movable plate 701, the outer wall of the movable plate 701 is slidably connected to one side of the auxiliary rod 5, a limiting frame 702 is fixedly connected to one side of the bow 2, and a positioning component is installed at the top of the movable plate 701 to limit the sliding between the movable plate 701 and the auxiliary rod 5.

[0020] The positioning assembly includes a positioning threaded rod 703, the outer wall of which is threaded to the inner wall of the moving plate 701, and a positioning groove for matching the outer wall of the positioning threaded rod 703 is provided on one side of the auxiliary rod 5.

[0021] A first string 6 is installed between the other end of the bow 2 and one end of the auxiliary rod 5, and a second string 8 is installed between the soundbox 1 and the headstock 4.

[0022] One end of the bow 2 is fixedly connected to a handle, and the bottom end of the body 1 is fixedly connected to a base.

[0023] The soundbox 1 is the resonator of the erhu, a key component that determines the tone and volume. For portability, the integrity of the soundbox 1 must be maintained. When using the bow 2, the auxiliary rod 5 is rotated, and then the angle between the bow 2 and the auxiliary rod 5 is fixed by the reinforcing component 7. The moving plate 701 is moved, and its outer wall contacts the interior of the limiting frame 702. The positioning threaded rod 703 is rotated, and it rotates and moves, contacting the interior of the positioning groove. This restricts the position of the moving plate 701, thereby achieving relative fixation between the bow 2 and the auxiliary rod 5. The user can control the bow 2 by holding the lever.

[0024] Moving the headstock 4 changes the relative position between the first cylinder 301 and the first rod 302. When the limiting member 304 contacts the area of ​​the positioning hole, the outer wall of the limiting member 304 contacts the inner wall of the positioning hole under the action of the spring 303, thus enabling the telescopic member 3 to unfold. The first string 6 and the second string 8, due to their flexibility, do not require restriction. By setting the telescopic member 3 fixed at the top of the body 1, the headstock 4 and the body can be quickly extended and securely locked, avoiding frequent disassembly. The resulting joint loosening problem ensures the stability of pitch. At the same time, the bow 2 and the auxiliary rod 5 are connected and fixed by a reinforcing component 7 with a sliding movable plate 701 and a positioning threaded rod 703. This mechanical locking method is more stable and reliable than simple plug-in or folding joints, ensuring the rigidity of the overall structure during performance. The portable design focuses on the bow 2 length adjustment (telescopic component 3) and auxiliary support (auxiliary rod 5), while the key sound-producing and resonating component (body 1) maintains its traditional and complete form, thus ensuring the feasibility of playing this portable erhu.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
