Description

Technical Field

[0001] This invention relates to a traditional Chinese musical instrument, and more particularly to a structural improvement of a combined retro-style guqin. Background Technology

[0002] The guqin is a traditional musical instrument, typically consisting of a body composed of a soundboard and a backboard. The cavity between the two forms a resonating chamber. The body is elongated with an arc-shaped cross-section. At the end of the soundboard is the headstock, above which is a bridge, shaped like a protruding strip. The other end is the tailstock. Seven strings run along the long axis of the body, spaced apart and fixed at the headstock and tailstock. The tension and length of each string are adjustable. The player uses the fingers of both hands to pluck or press the strings. By varying the force of the plucking and pressing different positions on the strings, three different timbres are produced: harmonics, open strings, and stopped strings. The sound is transmitted through two sound holes on the backboard.

[0003] While the existing guqin construction is simple, it has significant drawbacks. The soundboard must not only bear the primary function of vibration and sound production but also act as the fingerboard for pressing and sliding during playing. It needs to vibrate easily to produce sound while maintaining a certain level of surface hardness and structural strength. Therefore, a thick soundboard results in a low volume, while a thin soundboard can increase volume but reduces the strength of the instrument, making it prone to deformation and affecting its usability. In other words, multiple variables (even contradictory variables) are controlled within a single component, resulting in poor stability and balance of the entire system.

[0004] The current vibration mode of the guqin transmits the vibration energy of the strings from the bridge to the solid wood part of the headstock. However, the bridge is located outside the effective cavity of the resonance chamber. This situation causes the vibration energy of the strings to be unable to be fully transmitted to the soundboard of the resonance chamber, resulting in a great waste of vibration energy. As a result, the volume of the guqin is generally much lower than that of other stringed instruments, making it difficult to play with other instruments.

[0005] The current production of the guqin involves two main processes: the wooden body and the lacquer application. The wooden body is made from a single piece of wood for the soundboard and another from a single piece of wood for the backboard. To ensure the soundboard can vibrate fully, the soundboard is usually made of soft woods such as paulownia or cedar. The process requires considerable time to shape the body, including the recesses, holes, and fittings. The lacquer application involves mixing deer antler powder and natural lacquer to create a putty, which is then applied to the surface of the wooden body. After it dries completely, it is sanded smooth. This process is repeated 3-5 times, each time taking 1-3 months. After the lacquer is applied, a topcoat is applied, which takes about a month. The total production cycle is approximately one year.

[0006] The prior art has the problems of high manufacturing difficulty, high cost, long cycle, high requirement for the technical level of workers, low production standardization level, easy deformation and cracking of the finished product, and high after-sales maintenance pressure. SUMMARY

[0007] The present application provides a combined retro qin with exquisite structure, resource saving, convenient industrialization processing, short production cycle and high sound intensity.

[0057] Embodiment one

[0058] The original ancient qin adopts a structure of a resonant cavity and a fingerboard integrated into the body, which requires a professional qin cutter to cut the qin, especially the groove abdomen, which is the most critical step to determine the sound quality of the ancient qin. It can be said that the level of a qin cutter is completely reflected in this step of digging the groove abdomen. When digging the groove abdomen, the qin cutter should dig while listening to the sound of the qin, and judge whether the structure and shape of the groove abdomen are reasonable through the sound, so that the qin cutter needs to have a pair of sensitive ears to clearly distinguish the sound emitted by different groove abdomen curves, and also can adjust in time according to the sound. The subtle skills of the thickness ratio of different structures of the body and the structure of the groove abdomen all need to rely on the rich experience of the qin cutter, so the sound quality of a qin is completely controlled by the experience of the qin cutter, and there are many uncertain factors, which not only low efficiency but also difficult to control the quality. Thus, the sound effect of the ancient qin is weak, the price difference is great, the learning and using cost is high, the difficulty is great, and overall it is not conducive to the popularization and development of the ancient qin instrument, and the popularization degree is far lower than that of the Chinese zither, pipa, guitar and other national musical instruments and western musical instruments.

[0059] The present embodiment refers to Figures 1-4 As shown in the figure, a combined retro qin comprises:

[0060] The resonator 100 can be made of natural wood such as cedar, paulownia, maple, catalpa, cherry, mahogany, and peach hearth, or it can be made of plywood, MDF, and other boards.

[0061] The neck 200 is fixedly connected to the end of the soundbox 100. The neck 200 can be made of natural wood such as maple, cherry, mahogany, or plywood, or it can be made of plywood, MDF, or other boards.

[0062] The fingerboard 300 is fixedly mounted above the soundbox 100, with one end fixedly connected to the soundbox 100 and the other end fixedly connected to the neck 200. The fingerboard is made of hardwood, such as ebony, mahogany, blackwood, or rosewood. Its construction eliminates the need for using deer antler powder and raw lacquer to create the ash base, reducing manufacturing difficulty, production cycle, and production cost. The function of the fingerboard 300 in the guqin is to allow the left hand to press the strings and transmit vibrations to the soundbox 100.

[0063] The lower string bridge 400 is fixedly installed on the top of the resonance box 100 and is used to conduct the vibration energy of the strings. In actual production, the lower string bridge can be solid or decorated with carved patterns and openwork designs on the guqin.

[0064] The tuning mechanism 500 tightens several strings onto the lower string bridge 400. In this case, the lower string bridge 400 is directly connected to the soundboard of the resonator 100, thereby reducing the loss of string vibration energy. The similar structure of the traditional guqin is located at one end of the headstock, outside the resonator, resulting in a large loss of string vibration energy.

[0065] More specifically, the resonance box 100 includes:

[0066] Side panel of the soundbox 110,

[0067] A soundbox panel 120 is fixedly mounted on the top of the soundbox side panel 110; and

[0068] The bottom plate 130 of the soundbox is fixedly installed at the bottom of the side panel 110 of the soundbox and is provided with a sound hole.

[0069] More specifically, the width of the resonator 100 decreases sequentially from the head end to the tail end.

[0070] Further optimization involves adapting the neck 200 to the resonator 100 and providing a support foot 210 at the bottom. In this case, the support foot 210 has an L-shaped structure, which can stably support the guqin on a table or hang it on a wall.

[0071] Further optimization, the fingerboard 300 is provided with a plurality of tuning pegs 301 near the edge for marking the prompt pitch.

[0072] Further optimization, one end of the fingerboard 300 is located at the top of the resonance box 100 near the middle position.

[0073] Further limitation, the width of the fingerboard 300 decreases from one end near the head to the other end near the tail.

[0074] Further optimization, the fingerboard 300 is provided with a spacing between the resonance box 100, except for the end connected to the resonance box 100, the rest of the part across the resonance box 100. The design of the fingerboard and the resonance box can make the resonance box panel vibrate fully.

[0075] The existing technology of Guqin also has some disadvantages in use, such as inconvenient installation and replacement of strings, low stability of string pulling device, easy string loosening, inconvenient tuning and low precision, etc.

[0076] Further optimization, the tuning mechanism 500 comprises:

[0077] The string board 510 is fixedly connected with the fingerboard 300 and is provided with a plurality of string holes 511 for threading the strings, and the Guqin usually has 7 strings, i.e. the string holes 511 are arranged at intervals of 7;

[0078] In the case, the connecting side of the string board 510 and the fingerboard 300 is in U-shaped structure, which is used to accommodate the end of the fingerboard 300, and facilitates the rapid assembly of the Guqin.

[0079] The upper string bridge 520 is fixedly arranged at the top of the string board 510 and is used to support the strings, and the length thereof is matched with the string part, and after installation, the top surface of the upper string bridge 520 is higher than the top surface of the fingerboard 300; the distance between the upper string bridge 520 and the lower string bridge 400 is the effective string length, i.e. the effective vibration length of the strings;

[0080] The string seat 530 is fixedly connected with the end of the resonance box 100;

[0081] Referring to Figure 5 , Figure 6 as shown;

[0082] A plurality of string posts 540 are movably arranged at the top of the string seat 530;

[0083] A plurality of knobs 550 are movably arranged at the side of the string seat 530 and are in transmission connection with the corresponding string posts 540, and through the rotation of the knob 550, the string post 540 in transmission connection therewith is rotated, so as to wind or unwind the strings.

[0084] The number of the plurality of strings 540 is equal to the number of the plurality of knobs 550, and one-to-one correspondence is established. In the present case, the string column and the string knob adopt a worm type structure, but a planetary gear type structure can also be adopted.

[0085] The traditional Chinese zither fretboard and the resonance box bear multiple functions for the same component, thereby increasing the difficulty of production and the instability of use. In the present embodiment, the functions are distributed to the corresponding components in the form of separation of variables, each performs its own function, and the problems can be solved locally, completely changing the original structure. The independent fretboard and the independent resonance box improve the stability and balance of the entire system. At the same time, resonance boxes of different sizes and lengths can be made according to the needs of timbre, for example, the resonance box can be shortened for bright timbre, and the resonance box can be lengthened for deep timbre, thereby increasing the richness of the timbre.

[0086] The lower string bridge is arranged on the upper surface of the panel of the resonance cavity, and the vibration energy of the string is directly transmitted to the panel of the resonance cavity, thereby greatly improving the sound intensity, and the volume can be doubled without opening the electronic loudspeaker.

[0087] The size, length and shape of the resonance box can be adjusted as needed (according to the needs of visual aesthetics and timbre, bright timbre short, thin, narrow resonance box, low timbre long, thick, wide resonance box, without affecting the performance). The panel and the bottom plate of the resonance box can be flat or arc; whether the panel and the bottom plate of the resonance box are perforated, the size and number of the perforations can be changed as needed.

[0088] Embodiment two

[0089] Further improve the volume and sound quality of the Chinese zither, the top surface of the resonance box 100 is provided with an electronic pickup 610;

[0090] The electronic pickup 610 picks up the string sound through the sound effect adjusting panel 620 on the resonance box 100 and outputs it from the loudspeaker.

[0091] The electronic pickup can be externally connected to an amplification device to further expand the volume, but an electronic volume expander can also be installed, without the need for an external amplification device to play a certain volume amplification role, so the electronic volume expander is an alternative.

[0092] The sound effect adjusting panel 620 adjusts the volume, high and low sound intensity, reverberation size and audio output.

[0093] In the present case, the loudspeaker is fixedly arranged on the panel at the top of the resonance box 100, below the fretboard 300. The electronic pickup 610 in the present case can be set in three modes:

[0094] 1. Turn off the pickup, and let the resonance box 100 of the zither vibrate to produce sound;

[0095] 2, open the pickup + built-in speaker;

[0096] 3 open the pickup + external speaker.

[0097] The top of the resonance box 100 is provided with a sound post 700 extending into the sound cavity. The sound post 700 is used to connect the resonance box panel and the resonance box bottom plate, which can strengthen the resonance box strength and transmit the panel vibration to the bottom plate.

[0098] Example three

[0099] Referring to Figures 7-9 The end of the neck 200 is fixedly connected with the end of the resonance box 100, and the length of the resonance box 100 is greater than the length of the neck 200.

[0100] Referring to Figure 3 The length of the resonance box 100 is less than the length of the neck 200.

[0101] Bright tone can shorten the resonance box, and deep tone can lengthen the resonance box.

[0102] Example four

[0103] Referring to Figure 10 The end of the neck extends into the resonance cavity, close to the directly below the lower bridge, so as to improve the overall rigidity and reduce the stress of the resonance cavity panel and bottom plate caused by the tension of the strings, and improve the vibration response.

[0104] Example five

[0105] Further development, referring to Figure 11 The end of the fingerboard 300 extends from above the neck 200, and the strings pass from the left end of the fingerboard to the neck 200 below the fingerboard 300.

[0106] In summary, the connection mode of the resonance box, the fingerboard, the neck, the tuning mechanism, the electronic pickup and the like in the case is usually adhesive bonding and / or screw connection, but mortise and tenon connection and hinge connection can also realize the technical scheme of the present application, so mortise and tenon connection and hinge connection are alternative schemes.

[0108] (1) The embodiment disclosed in the case only involves the structure involved in the embodiment disclosed in the case, and other structures can refer to the usual design.
