Description

Technical Field

[0001] The invention belongs to the technical field of guqin musical instruments, and particularly relates to a guqin body. Background Art

[0002] The guqin, also known as the yaoqin, yuqin, sitong, and seven-stringed qin, is a traditional Chinese musical instrument with a history of at least 3,500 years. Ancient texts record that Fuxi invented the qin, while legends also abound about Shennong, Huangdi, and Tang Yao. Shun established the qin with five strings, King Wen added another, and King Wu, after defeating King Zhou, added another string, bringing the total to seven. This demonstrates the profound and extensive nature of guqin culture. The guqin, with its 13 frets that symbolize musical scale, is also a ritual instrument and a musical instrument for regulating musical temperaments, belonging to the category of the eight musical instruments, the silk. The guqin boasts a wide range, a deep timbre, and a long-lasting lingering sound. Since ancient times, the term "qin" has been used specifically for it, but in the 1920s, it was renamed guqin to distinguish it from the piano. There are sayings about the qin: "A scholar never puts away his qin without a reason" and "the qin is on the left, the calligraphy on the right." The qin ranks first among the four traditional arts of Chinese culture: qin, chess, calligraphy, and painting. It is considered a symbol of elegance and served as an accompaniment to the recitations of scholars. Since ancient times, it has been essential knowledge and a compulsory subject for many scholars. The qin features in numerous poems and essays. Ji Kang's "Ode to the Qin" states: "Among all instruments, the qin possesses the greatest virtue." The qin is more than just a musical instrument; it represents a spiritual way of life through which scholars and literati cultivate their character and even attain enlightenment.

[0003] Guqin production is largely based on traditional methods, passed down orally and cultivated through familiar techniques. While the guqin's mid- and low-pitched notes are long and melodious, the high notes are more challenging to create. To date, no one has developed a structure that can produce these high notes. Summary of the Invention

[0004] The purpose of the present invention is to provide a guqin body to address the problems existing in the prior art. This structure adds a high-frequency sound pool in the belly of the guqin groove and adds high-frequency sound absorption in the high-frequency sound pool without changing the original guqin shape, fully responding to the high-pitch excitation of the strings, obtaining a relatively ideal high-frequency tone, and making the mid- and low-frequency tones richer, thereby enhancing the artistic charm of the guqin.

[0005] The technical solution of the present invention is:

[0006] A guqin body, comprising a panel at the top and a bottom plate at the bottom, a groove being formed on the back side of the panel, a dragon pool sounding device and a phoenix marsh sounding device being provided in the groove, at least one high-frequency sound pool being provided in the groove, the high-frequency sound pool being located on the longitudinal center axis of the panel groove or the longitudinal center axis being biased toward the treble strings, the thickness of the panel at the location of the high-frequency sound pool being thinner than the thickness of other parts of the panel groove, a high-frequency sound pool being provided with a high-frequency sound pool having the same direction as the high-frequency sound pool, the width and length of the high-frequency sound pool being smaller than those of the high-frequency sound pool, the high-frequency sound pool being located in the middle of the high-frequency sound pool, and the height of the high-frequency sound pool being higher than the panel groove.

[0007] Specifically, the high-frequency sound pool is set as one, and the high-frequency sound pool is located at the head of the Fengzhao Nayinqin and is the head high-frequency sound pool.

[0008] Specifically, the high-frequency sound pool is set as one, and the high-frequency sound pool is located at the tail of the piano and is the tail high-frequency sound pool.

[0009] Specifically, the high-frequency sound pool is set as one, and the middle high-frequency sound pool is located between the Fengzhao Na Yin and the Longchi Na Yin.

[0010] Specifically, there are two high-frequency sound pools, one of which is located between Fengzhao Nayin and Longchi Nayin and is the middle high-frequency sound pool, and the other is located at the head of the piano corresponding to Fengzhao Nayin and is the head high-frequency sound pool.

[0011] Specifically, there are two high-frequency sound pools, one of which is located at the head of the piano corresponding to the Fengzhao sound setting and is called the head high-frequency sound pool, and the other is located at the tail of the piano corresponding to the Longchi sound setting and is called the tail high-frequency sound pool. The length, width and height of the head high-frequency sound pool are respectively greater than the length, width and height of the tail high-frequency sound pool.

[0012] Specifically, there are three high-frequency sound pools, namely a head high-frequency sound pool set at the head of the piano corresponding to the Fengzhao Na Yin, a tail high-frequency sound pool set at the tail of the piano corresponding to the Longchi Na Yin, and a middle high-frequency sound pool located between the Fengzhao Na Yin and the Longchi Na Yin. The length, width and height of the head high-frequency sound pool are respectively larger than the middle high-frequency sound pool, and the length, width and height of the middle high-frequency sound pool are respectively larger than the length, width and height of the tail high-frequency sound pool.

[0013] Specifically, the high-frequency sound pool is in the shape of a strip, a rectangle, an oblong, or an ellipse.

[0014] The high-frequency sound pool and high-frequency sound absorption described in this application are on the longitudinal center axis of the panel groove or on the side of the longitudinal center axis biased towards the treble strings. They fully respond to the treble excitation of the strings, allowing the treble of the guqin to revolve around the beams and obtain a relatively ideal high-frequency tone, so it is named high-frequency.

[0015] The beneficial effects of the present invention are as follows: the latest engineering vibration analysis technology is used to transform the guqin. Without changing the original shape of the guqin, a high-frequency sound pool is excavated in the high-pitched area inside the belly of the guqin groove to increase the high-frequency sound pool, and high-frequency sound is added to the high-frequency sound pool, which fully responds to the high-pitched excitation of the strings, so that the high-pitched sound of the guqin revolves around the beams, obtaining a relatively ideal high-frequency tone, while the multi-level expression of the mid- and low-frequency tones is richer, thereby enhancing the artistic charm of the guqin.

[0021] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] This embodiment provides a guqin body such as Figure 1 As shown, a guqin body is shown, which includes a panel located at the upper part and a bottom plate at the lower part. A groove is excavated on the back side of the panel, and a dragon pool sounding device 1 and a phoenix marsh sounding device 2 are provided in the panel groove. A high-frequency sound pool structure located at the head part of the instrument is excavated in the panel groove at a position corresponding to the treble. The high-frequency sound pool structure includes a head high-frequency sound pool 3, and a head high-frequency sound pool 4 is provided in the head high-frequency sound pool 3 in the same direction as the head high-frequency sound pool. The length of the head high-frequency sound pool 4 is smaller than the head high-frequency sound pool 3, and the large high-frequency sound pool 4 is located in the middle part of the head high-frequency sound pool 3. The thickness of the panel at the part where the head high-frequency sound pool 3 is located is smaller than the thickness of other parts of the panel, and the thickness of the head high-frequency sound pool 4 in the head high-frequency sound pool 3 is greater than the thickness of the panel groove. The head high-frequency sound pool 3 described in this embodiment is located on the longitudinal center axis of the panel groove toward the treble string side. Since it is a hand-excavated groove structure, the long strip edge of the head high-frequency sound pool 3 is irregular.

[0024] The key to a guqin's ability to produce beautiful and melodious sound lies in the carving of its belly. The belly of a guqin is a complex, irregularly curved surface. Experienced luthiers perform sound testing while carving the belly, judging the sound's rationality and shape based on the sound. Each panel is individually tailored to its specific needs. A hard, dense material produces a high-frequency, pure sound; a panel with a uniform thickness produces harmonious or nearly harmonious overtones; a panel thick at the edges and thin in the middle produces a hollow, soft sound; a panel thin at the edges and thick and raised in the middle produces a solid, hard sound, increasing the width of the vibration response area. Therefore, in the past, guqins crafted based on the selection of materials often had relatively simple structures, which had no significant impact on or alteration of their sonic characteristics.

[0025] The so-called Na Yin is a protruding part specially made inside the piano case (at the bottom of the panel). Its shape is generally the same as the sound groove. The size and height of the Na Yin must match the thickness of the panel. In addition, appropriate space needs to be left between the Na Yin and the Dragon Pool and Phoenix Marsh to facilitate the diffusion of sound outside the piano body. If the panel is thinner and the volume is louder, the Na Yin will be slightly wider, longer and thicker.

[0026] Since the bottom of the panel groove belly and the string part of the panel part of the guqin are arranged relative to each other, when the guqin part is played, the vibration of the string fluctuation drives the vibration of the panel groove belly of the guqin, and the vibration of the panel groove belly drives the vibration of the air, producing the guqin's unique and ancient tone. According to the groove belly structure provided in this embodiment, the high-frequency sound pool 3 of the head is dug out, and high-frequency sound is added to the high-frequency sound pool, which fully responds to the high-pitched excitation of the strings, so that the high-pitched sound of the guqin revolves around the beam, obtaining a relatively ideal high-frequency tone, and the multi-level performance of the mid- and low-frequency tones is richer, thereby enhancing the artistic charm of the guqin.

[0027] Example 2

[0028] like Figure 2The figure shows a schematic diagram of a guqin body provided by this embodiment, which is different from the embodiment 1 in that: the high-frequency sound pool structure in the panel groove of the guqin body is set to two, and there are two corresponding high-frequency sound pools. One high-frequency sound pool corresponds to the phoenix pond sound 2 and is located at the head of the guqin as the head high-frequency sound pool 3, and the other is located at the tail of the guqin as the tail high-frequency sound pool 5 corresponding to the dragon pond sound 1. The head high-frequency sound pool 3 is also provided with a head high-frequency sound 4 in the same direction as the head high-frequency sound 4, and the tail high-frequency sound pool 5 is provided with a tail high-frequency sound 6 in the same direction as the tail high-frequency sound 6. The thickness of the panel where the sound pool 3 and the tail high-frequency sound pool 5 are located is thinner than the thickness of other parts of the panel. The thickness of the head high-frequency sound pool 4 in the head high-frequency sound pool 3 is thicker than the thickness of other parts of the panel. The thickness of the tail high-frequency sound pool 6 in the tail high-frequency sound pool 5 is thicker than the thickness of other parts of the panel. The length, width, and height of the head high-frequency sound pool 3 are respectively larger than the length, width, and height of the tail high-frequency sound pool 5. The shapes of the head high-frequency sound pool 3 and the tail high-frequency sound pool 5 are both long strips. Due to the hand-cut groove belly structure, the edges of the head high-frequency sound pool 3 and the tail high-frequency sound pool 5 in the actual groove belly are irregular. The principle is the same as that of the embodiment and will not be repeated.

[0029] Example 3

[0030] like Figure 3 The figure shows a schematic diagram of a guqin body provided by this embodiment, which is different from the embodiment 1 in that: the high-frequency sound pool structure described in the groove-belly structure is set to three, and the corresponding high-frequency sound pools are three, namely a head high-frequency sound pool 3 provided at the head of the guqin, a tail high-frequency sound pool 5 provided at the tail of the guqin, and a middle high-frequency sound pool 7 located between the phoenix pond sound 2 and the dragon pond sound 1. The thickness of the panel at the location of the head high-frequency sound pool 3, the middle high-frequency sound pool 7, and the tail high-frequency sound pool 5 is less than the thickness of other parts of the panel. The head high-frequency sound pool 3 is also provided with a head high-frequency sound pool 4 that is consistent with its direction. The sound pool 5 is provided with a tail high-frequency sound absorber 6 that is aligned with the sound pool 5, and a middle high-frequency sound absorber 8 that is aligned with the sound pool 7. The thickness of the head high-frequency sound absorber 4 in the head high-frequency sound pool 3 is greater than the thickness of other parts of the panel, the thickness of the tail high-frequency sound absorber 6 in the tail high-frequency sound pool 5 is greater than the thickness of other parts of the panel, and the thickness of the middle high-frequency sound absorber 8 in the middle high-frequency sound pool 7 is greater than the thickness of other parts of the panel. The length, width, and height of the head high-frequency sound pool 3 are respectively greater than those of the middle high-frequency sound pool 7, and the length, width, and height of the middle high-frequency sound pool 7 are respectively greater than those of the tail high-frequency sound pool 5. The principle is the same as that of the embodiment and will not be repeated here.

[0031] Example 4

[0032] like Figure 4The figure shows a schematic diagram of a guqin body provided by this embodiment. The trough-belly structure comprises two high-frequency sound pools. One high-frequency sound pool is located between Fengzhao Nayin 2 and Longchi Nayin 1, and is referred to as the middle high-frequency sound pool 7. The other high-frequency sound pool is located at the head of the guqin, corresponding to Fengzhao Nayin 2. A middle high-frequency sound pool 8 is located within the middle high-frequency sound pool 7, and a head high-frequency sound pool 4 is located within the head high-frequency sound pool 3, which is aligned with the middle high-frequency sound pool 7. Both the middle high-frequency sound pool 7 and the head high-frequency sound pool 3 are in the same direction. The principles behind this are the same as those in the embodiment and will not be further elaborated.

[0033] In summary, the trough structure provided by the present invention is variable, and the width and length of its high-frequency sound pool are set and adjusted according to the overall situation of the guqin during the production process. High-frequency sound pools set in different positions will have different timbres, which can also be adjusted during the production process. The number of high-frequency sound pools described in this application can also be set to four or more, and can be set and adjusted according to the overall situation of the guqin. Because the trough of the guqin is excavated by hand, its shape will not be as neat as shown in the figure. The general outline may be an oblong, square, rectangular, etc., with unclear edges. However, any sound pool shape and structure formed as described above, and equipped with a sound source within the sound pool, are protected by this patent.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for protection of the present invention.
