Integral structure of ancient musical instrument

Fig. 1 is a schematic structural view of an organ 1 according to an embodiment of the present invention, including: a panel 11, strings 13 and mountains 14 erected on the panel 11, and a bottom plate 12. As shown in fig. 1, the mountain 14 is erected vertically in front of the exposed portion 111 of the panel 11, and the mountain 14 is provided with string eyes for threading strings 13. The strings 13 of the Guqin include 1 to 7 strings and extend from the gum parts 112 of the face plate 11 to the mountain 14, respectively, and are fixed to the string eyes. Of the strings 13, 1 to 3 strings are bass strings, the area where the strings are located is called "bass zone", 4 strings are middle strings 13,5 to 7 strings are treble strings, and the area where the strings are located is called "treble zone". Thirteen logo positions 15 are arranged on the panel 11, naming rules are one logo, six logos and twelve logos waiting, and each logo position 15 actually represents a reference plane perpendicular to the panel 11. Thus, by staggering the logo positions 15 and strings 13, the positions on the face plate 11, e.g., one logo 7 string, four logo 4 strings, etc., can be located.

In the ancient organ, further, 1-7 strings extend from the dragon gum part 112 to the Yue mountain 14, and pass through the position of the four emblems 154 of the panel 11, which is located in the reference plane perpendicular to the panel 11, and extends upwards by 7.1-7.3 mm until contacting with the Yue mountain 14 and being fixed on the Yue mountain 14. When the string 13 is in contact with the mountain 14, the mounting height of the mountain 14 is defined as the mounting height of the mountain 14. Moreover, the surface between the four emblems 154 and the dragon gum portion 112 of the panel 11 is concave relative to the connecting line between the four emblems 154 and the dragon gum portion 112, and the maximum concave distance is 1.2-1.3 mm.

Experiments prove that the slightly concave surface from the four emblems 154 to the dragon gum part 112 is the optimal structure for avoiding the occurrence of brake sound and clapping plate, and the sound effect of the ancient musical instrument can be improved to different degrees by limiting the concave distance. Wherein, because the external forces for exciting the strings 13 to generate mechanical vibration are different, the larger external forces increase the vibration quantity of the strings 13, and the strings 13 are easy to flap the surface, so that the string distance needs to be increased; however, if the string pitch is far greater than the amplitude of the strings 13, the playing skill of the string is affected again, the user experience (i.e., feel) is further affected, which is a very important factor from the point of use of the stringed instrument, and the incompatibility of the appearance of the seven-stringed instrument is also increased.

Specifically, the highest point of the face shown in fig. 1 is four logo 154 points, and the 1 string 131 extends from the gum portion 112 to the forehead 1615 and passes through a position 7.2mm directly above the four logo 154 points until the 1 string 131 contacts the mountain 14, which is the mounting height of the mountain 14, that is, the minimum hmin of the distance of the portion of the mountain 14 protruding from the face plate 11 of the guqin. Because the mountain 14 is also provided with the string hole, and the string hole is arranged at a position slightly lower than the top of the mountain 14, the actual installation height h of the mountain 14 is larger than hmin; in another embodiment, the chord eye may be positioned on top of the mountain 14, and the mounting height of the mountain 14 may then be equal to hmin.

With four emblem 154 points as nodes, the plane perpendicular to the organ panel 11 where the four emblems 154 are located divides the organ panel 11 into two sections: the first section is from the dragon gum part 112 to the four emblems 154 and is provided with a first section of piano face; the second segment is from four emblems 154 to the mountain 14 and has a second segment of face. According to experimental verification, the structure of the first section of the piano face is a main factor affecting Gu Qinyin efficiency. In general, when the height of the string 13 from the four emblems 154 becomes smaller, the concave distance of the corresponding first segment of the face of the string 13 becomes smaller, specifically determined according to the diameter of the string 13. In the embodiment, when the 1 string 131 is 7.2mm higher than the four emblem 154 points, the midpoint of the first section of the piano face is selected to be the lowest point of the concave, and the concave distance is 1.3mm; the distance between the 4 strings and the four emblems 154 is 7.16mm, and the corresponding first section of the piano face is concave by 1.28mm; the 7 strings are 7.15mm higher than the four emblems 154, the corresponding first section of the strings are concave at a distance of 1.28mm, the rest strings 13 are sequentially erected on the ancient musical instrument panel 11 according to the assembly sequence, the heights of the strings are different from each other, and the control tolerance is within +/-0.1 mm. At this time, when the strings 1313 are excited by external force to make sound, the guqin does not generate a brake sound similar to a sand sound and/or a sound of beating the strings 1313 to the surface, and the strings 13 are plucked, so that the strings 13 can be easily pressed, the strings 13 also maintain the elasticity, and the user experience (hand feeling) is optimal.

In addition, the goose feet 17 are further arranged on the bottom plate of the ancient musical instrument, and the function of supporting the ancient musical instrument is achieved.

Vertical deformation consistency structure of mountain supporting and exposing surface bottom plate

In an embodiment, the guqin 1 is further provided with a structure of uniform deformation of the mountain 14, the bearing 111 and the face base plate 12 in the vertical direction, so as to avoid the problems of protruding the mountain 14 from the boundary of the face/base plate 12 and paint cracks caused by deformation of the face plate 11 or the base plate 12. Fig. 10 is a schematic diagram of a structure of uniform deformation of the mountain 14, the exposure and the face bottom plate 12 in the vertical direction in an embodiment of the present invention, the structure mainly comprises an guqin panel 11, the mountain 14 vertically disposed at the exposure portion 111 of the guqin panel 11, the guqin bottom plate 12, the support bar 18 and the seal 19, wherein the outer surface of the exposure portion 111 is provided with a first groove 113, the first groove 113 horizontally penetrates through the outer surface of the exposure portion 111 along the long axis direction thereof, and the longitudinal depth of the first groove 113 is smaller than the thickness of the exposure portion 111; the inner surface of the exposed part 111 is provided with a second groove 114, the second groove 114 is positioned below the side of the first groove 113, the longitudinal depth of the second groove 114 is smaller than the thickness of the exposed part 111, and the supporting bar 18 is assembled in the second groove 114; the ancient organ bottom plate 12 is provided with a third groove 121 corresponding to the position of the second groove 114, and the third groove 121 longitudinally penetrates through the ancient organ bottom plate 12; the seal 19 is placed in the third groove 121 for blocking the support bar 18 to fill the bottom plate 12 of the ancient organ; wherein the length of the third groove 121 is greater than the length of the second groove 114 and less than the length of the first groove 113.

Specifically, the side of the face plate 11 on which strings 13 are laid is called the face, which is also the outer surface of the face plate 11, and for aesthetic purposes, the face has a slight arc, i.e., a slight bulge in the surface between the two long sides of the face plate 11. The texture direction of the panel 11 is substantially the same as the longitudinal direction of the panel 11. The upper part of the mountain 14 is a meniscus and the lower part connected to the upper part is a rectangular plate. The texture direction of the Yueshan 14 is perpendicular to the texture direction of the face plate 11.

FIG. 2 is a schematic view of the bottom surface of an ancient organ in an embodiment of the invention, showing the structure of the Yue mountain 14, the bearing dew and the vertical deformation uniformity of the face-bottom plate 12. Fig. 3 is a partial enlarged view at a in fig. 2.

The outer surface of the exposed portion 111 is provided with a first groove 113, and the first groove 113 horizontally penetrates through the outer surface of the exposed portion 111 along the long axis direction, and the longitudinal depth of the first groove 113 is smaller than the thickness of the exposed portion 111. The first slot 113 is used to mount the mountain 14. On the exposed portion 111, a position at a first predetermined distance from the guqin forehead 16 in the direction of the short side of the guqin is recessed downward to construct a first groove 113, which is 10cm in this embodiment. The first groove 113 is a rectangular groove, and is symmetrical about the long axis of the organ. The first slot 113 corresponds to the shape of the Yue mountain 14, having a length 165mm, a width 11mm, and a depth 25mm. After the musical instrument, the mountain 14 is perpendicular to the exposed portion 111 and is located on the outer surface of the face plate 11, and is caught in the first groove 113 and fixed by means of bonding. It should be noted that the depth of the first groove 113 may not be greater than the thickness of the exposed portion 111.

The inner surface of the panel 11 is a surface for bonding with the bottom plate 12 on the panel 11. As seen from fig. 2, the inner surface of the panel 11 is recessed upward in the direction of the short side of the organ at a position spaced from the organ portion 16 by a second predetermined distance, which in this embodiment is 12cm, to form a second groove 114. The second grooves 114 are parallel to the first grooves 113, and the horizontal distance between the long axes of the first grooves 113 and the second grooves 114 is 2mm. The second slot 114 has a length of 135mm, a width of 24mm and a depth of 7mm. The second grooves 114 have a longitudinal direction of the panel 11 and a width direction of the panel 11. The second grooves 114 are provided for receiving the support bars 18 therein, and the support bars 18 function to prevent the contraction of the panel 11 in the deformation direction due to the dehydration for a long time. The deformation direction is a direction perpendicular to the texture of the panel 11. The deformation direction of the panel is perpendicular to the texture direction of the panel.

In this embodiment, the support bar 18 is a rectangular block corresponding to the shape of the second slot 114. The support bars 18 are inserted into the second grooves 114 and fixed to the inner surface of the panel 11 by adhesion. The support bar 18 has a length 81mm, a width 22mm and a thickness 12mm. The support bar 18 prevents the panel 11 from shrinking in the short side direction thereof, thereby maintaining the shape of the exposed portion 111, and preventing the mountain 14 from protruding from the panel 11 in the short side direction of the panel 11.

It should be noted that the thickness of the support bar 18 may be greater than the depth of the second slot 114, i.e., the support bar 18 may be higher than the second slot 114 after the support bar 18 is inserted into the inner surface of the panel 11, in order to allow the support bar 18 to partially penetrate the bottom plate 12 to better fix the relative positions of the panel 11 and the bottom plate 12 when the panel 11 and the bottom plate 12 are assembled.

Further, in this conforming structure, a third slot 121 is provided in the base plate 12, the third slot 121 corresponding to the orientation of the second slot 114 and extending through the base plate 12. The third groove 121 is a rectangular groove, and after the bottom plate 12 is attached to the panel 11, the third groove 121 is located right under the second groove 114, and the support bar 18 partially penetrates into the third groove 121 without penetrating through the bottom plate 12. The consistency structure further comprises a seal 19, the seal 19 is consistent with the shape of the third groove 121, is a rectangular plate and has a length 134mm and a width 23mm, and the thickness is determined according to the thickness of the support bar 18, and the determination conditions are as follows: the sum of the thicknesses of the support bar 18 and the seal 19 is equal to the sum of the depths of the second groove 114 and the third groove 121, and in this embodiment, the thickness of the seal 19 is 3mm. The third groove 121 has a longitudinal direction which is a short side direction of the bottom plate 12 and a width direction which is a long side direction of the bottom plate 12. The seal 19 is placed in the third groove 121 to block the support bar 18 and fill the bottom plate 12. Further, the seal 19 can hold the base plate 12 against shrinkage deformation in the short side direction thereof, maintaining the original shape of the base plate 12.

In another embodiment, the direction of the grain of the supporting bar 18 may be perpendicular to the direction of the grain of the panel 11, so that if the supporting bar 18 also contracts and deforms, the deformation direction is the width direction, so that the original length is maintained in the length direction, and the original abutting action is maintained without contraction.

The structure is arranged on the inner surface of the panel 11 and comprises the panel 11, a first nano-tone 117, a second nano-tone 118 and a reinforcing rib 119. As above, the outer surface of the panel 11 has an arc and slightly raised, and is marked with thirteen logo positions 15; the inner surface faces the base plate 12. The first nano-tone 117 is positioned in the large groove abdomen of the panel 11 and corresponds to the position of the sound outlet hole- "Longchi 122" of the bottom plate 12; the second nano-sound 118 is positioned in the lower abdomen of the panel 11 and corresponds to the sound outlet hole of the bottom plate 12, namely the position of the 'Feng Zhu 123'.

The panel 11 is a rectangular plate and comprises an outer surface with a convex cambered surface and an inner surface with a concave cambered surface; a row of logo 15 is marked on one side of the outer surface along the long axis direction of the panel 11; the inner surface is provided with a post portion 115 and a post portion 116 and faces the harp base plate 12; the side of the outer surface where the logo 15 is located corresponds to the bass side 200 of the inner surface and the side of the outer surface away from the logo 15 corresponds to the treble side 100 of the inner surface;

It should be noted that the distance between the highest point of the first and second humps and the base plate 12 of the organ cannot be less than 8mm, otherwise the air flow inside the organ is blocked, so that the sound of the organ cannot be effectively amplified for the first time inside.

Specifically, in the present embodiment, the inner surface of the panel 11 is provided with a ceiling column portion 115 and a ground column portion 116, the ceiling column portion 115 being a cylinder to symbolize "a circle", the ground column portion 116 being a square column to symbolize "a place". The inner surface of the panel 11 further comprises a high-pitched side 100 and a low-pitched side 200, wherein the low-pitched side 200 corresponds to the side of the panel 11 where the logo 15 is located, and the high-pitched side 100 corresponds to the side of the panel 11 far from the logo 15. The high-pitched side 100 and the low-pitched side 200 correspond to a "high-pitched region" and a "low-pitched region" on the outer surface of the panel 11, respectively. The treble string is mounted on the outer surface of the face plate 11 on the side remote from the logo 15, i.e. "treble zone".

The number of the splicing strips is 3-5, and the width of each splicing strip is reduced when the number of the splicing strips is increased. Fig. 8 is a schematic view of the structure of a splice plate 2 according to another embodiment of the present invention. Each splicing strip is a rectangular strip and is mutually adhered together, and the annual ring directions on the cross sections of the adjacent splicing strips are different. For example, if the number of splicing strips is 3, the annual ring direction on the cross section of the middle splicing strip is anticlockwise, and the annual ring direction on the cross section of the two side splicing strips is clockwise.

The base plate 12 is formed on the splice plate 2 formed by the above-mentioned splice bars through the scoring instrument. First and

second sound outlets

122 and 123, respectively referred to as "dragon pool" and "chicken biogas," are provided in the base plate 12, the first sound outlet 122 corresponding to the orientation of the first nano-tone 117 and the second sound outlet 123 corresponding to the orientation of the second nano-tone 118. The base plate 12 is provided with channels 124 for mounting the reinforcing bars 20. Two sides of each sound outlet are provided with a channel 124 perpendicular to the texture direction of the base plate 12. The channel 124 is a rectangular groove sunk into the bottom plate 12 with a certain thickness, and the reinforcing ribs 20 with the shape consistent with the channel 124 are embedded into the corresponding channel 124 to fill the concave position of the bottom plate 12, and are also used for fixing the splicing strips to avoid the bottom plate 12 from being scattered.

In another embodiment, two sides of the first sound outlet 122 are provided with channels 124, and one side of the second sound outlet 123 is provided with channels 124.
