Description

Technical Field

[0001] The invention belongs to the technical field of plucked string instruments, and in particular relates to a single-row string tremolo konghou. Background Art

[0002] The konghou is one of the oldest musical instruments in human history. It is a bow-shaped plucked string instrument evolved from a bow string. According to historical records, it has a history of nearly 3,000 years in China. However, due to its simple structure and single performance, it was not in line with the development trend of Chinese music aesthetics. It gradually faded out of people's sight during the Ming and Qing Dynasties and was lost for hundreds of years.

[0003] In the 1980s, the innovation and reform of konghou was launched again. In 1984, the applicant of this application successfully developed China's first "double-row string standing-type full-tuning konghou" based on the experience and lessons of the predecessors' reform of konghou. Therefore, domestic art colleges officially established konghou performance majors, and large-scale national orchestras were also listed as formally organized. The double-row string pedal-type full-tuning konghou is a multifunctional, newly designed new modern musical instrument. Therefore, it is inevitable that it is separated from the appearance of the ancient konghou and loses the cultural attributes and characteristics of the original konghou image that has been left to people for thousands of years.

[0004] Due to their admiration and nostalgia for the konghou culture, many people have begun to return to the ancient konghou production. Although the appearance has been restored, the sound and performance aspects cannot meet the modern people's demand for music performances. Summary of the invention

[0005] The present invention aims at the above problems and provides a single-row string konghou with tremolo function.

[0006] In order to achieve the above-mentioned purpose of the present invention, the present invention adopts the following technical scheme, which includes a bottom plate, on which a resonance box is arranged, and two ends of the resonance box are respectively connected to a column and a chord plate to form a konghou main body, the upper end of the chord plate is connected to the upper end of the column, and strings are arranged between the chord plate and the resonance box. It is characterized in that a suspension auxiliary beam is arranged between the column and the chord axis plate, and the suspension auxiliary beam is provided with staggered string-cutting nails cooperating with the strings.

[0007] As a preferred solution of the present invention, a pitch-changing device is provided on the auxiliary suspension beam corresponding to the strings, and the pitch-changing device includes a fixing frame arranged in the auxiliary suspension beam, a swing rod is provided on the fixing frame through a rotating shaft, and a string-cutting pile corresponding to the strings is provided on the swing rod.

[0008] As another preferred embodiment of the present invention, the resonance box comprises a box body, a concave sounding board is arranged on the upper surface of the box body, and the strings are connected to the concave sounding board.

[0009] Furthermore, sound collecting plates are arranged on both sides of the concave sounding board on the resonance box.

[0010] As a third preferred embodiment of the present invention, the resonance box comprises a box body, a convex sounding board is arranged on the upper surface of the box body, and the strings pass through the convex sounding board and are connected to the string hanging beam in the resonance box.

[0011] As a fourth preferred embodiment of the present invention, the width of the resonance board on the upper surface of the resonance box at one end located in the bass region is greater than that at one end located in the treble region.

[0012] The beneficial effects of the present invention are as follows: 1. The relatively displaced string-cutting nails provided on the auxiliary suspension beam of the present invention can effectively reduce the attenuation of the vibration energy of the strings. At the same time, each string is divided into an effective vibration resonance string section and a controllable tremolo string section between the resonance plate and the auxiliary suspension beam, and the effects in the middle and high pitch areas are obvious, so that one string is divided into two functional string sections, thereby improving the expressiveness of the konghou and better meeting the performance needs of modern people for music.

[0013] 2. The present invention is provided with a tuning device, the string-cutting post of the tuning device can change the effective vibrating string length, thereby achieving the purpose of tuning; the string-cutting post can change the tuning of individual strings, and can also be set to connect each group of octaves with a connecting rod to drive the string-cutting post to rotate and cut the string.

[0014] 3. In the preferred embodiment of the concave soundboard of the present invention, the bending direction of the concave soundboard is opposite to the pulling direction of the strings, which can greatly improve the tensile strength of the soundboard, making it less likely to deform and prolonging the life of the konghou. In addition, a sound collecting plate is arranged on the side of the concave soundboard to concentrate the volume and improve the volume of the resonance box.

[0015] 4. In the preferred embodiment of the convex soundboard of the present invention, the convex soundboard is not subjected to tension, and the tension is borne by the string hanging beam inside the resonance box, which can also improve the practical life of the resonance box and the konghou; at the same time, an angle is formed at the contact point between the strings and the convex soundboard, thereby generating pressure on the soundboard, thereby transmitting the vibration of the strings.

[0016] 5. The strings cooperate with the curved soundboard to transfer pressure and vibration to the curved soundboard, which has a better resonance effect.

[0017] 6. The resonance board of the resonance box is from wide to narrow. The narrow end matches the treble strings, which is conducive to high-frequency resonance; the wide end matches the bass strings, which is conducive to bass resonance. BRIEF DESCRIPTION OF THE DRAWINGS
