The transitional glissando can be clearly displayed, and combined with the joystick, more playing techniques can be produced.

[0017] 2.

[0018] 3. Due to the structure of the fixing device, when the positioning part is pushed to move, the positioning part moves to one end of the limit slot close to the rocker, driving the slider to slide as a whole; when the positioning part drives the pushing block to move to the end of the slide slot, the first inclined surface or the second inclined surface of the pushing block is in contact with the two fixing blocks, and under the action of the tightening spring, the two fixing blocks are retracted into the installation slot and do not contact the side walls of the accommodating slot, so that the positioning part can be freely slid to adjust the position of the positioning part; when there is no need to adjust the position of the positioning part, the positioning part is released, and under the action of the return spring, the pushing block is located on the side of the slider away from the rocker, and the two sides of the pushing block are in contact with the two fixing blocks, so that the two fixing blocks are pushed out of the installation slot and pressed against the slot wall of the accommodating slot, thereby facilitating the control of the movement and fixation of the positioning part.

[0026] The embodiment of the present application discloses a movable stringed plucked instrument, which provides a slider 14 on the instrument body 1. By moving the slider 14, the positioning portion 15 that presses the sliding string 3 is driven to slide along the length direction of the instrument body 1, thereby changing the vibration length of the sliding string 3, thereby emitting sounds of different pitches. In addition, the rocker 2 is added to enable the instrument to emit different sounds. The unique plucking technique solves the problem in the prior art that the monochord cannot make a good transition between notes when playing, resulting in poor performance. It can clearly display the transitional glissando, thereby improving the performance effect.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Example 1

[0029] Reference Figure 1 A mobile stringed plucked instrument includes a body 1, a rocker 2, and a sliding string 3. The body 1 is a hollow rectangular parallelepiped, serving as a large resonance box 21. The lower end of the rocker 2 is vertically fixed to one end of the body 1. The end of the body 1 provided with the rocker 2 is defined as the tail of the body 1, and the other end of the body 1 is the headstock. The rocker 2 is made of bamboo or ox horn and has a certain elastic deformation capability. Specifically, in the embodiment of the present application, there is a single sliding string 3, with its ends fixed to a position of the rocker 2 near the body 1 and to the other end of the body 1, respectively. The length of the sliding string 3 is substantially consistent with the length of the body 1.

[0030] Reference Figure 1 、 Figure 2 To clearly illustrate the transitions between notes, a partition 11 is fixedly mounted within the body 1, near the inner top of the body 1 and extending along the length of the body 1. The partition 11 and the sidewalls of the body 1 near the upper portion define a receiving slot 12. A strip-shaped slot 13 is defined on the upper end surface of the body 1. The strip-shaped slot 13 is shorter than the length of the slot 12 and is located on the body 1 away from the rocker 2. A slider 14 is slidably connected within the strip groove 13. A positioning portion 15 is fixedly mounted on the upper end of the slider 14. The positioning portion 15 includes a positioning rod 151 and a positioning ring 152. The lower end of the positioning rod 151 is mounted on the upper end surface of the slider 14. The positioning ring 152 is fixed to the upper end of the positioning rod 151, and the axis of the positioning ring 152 is parallel to the length direction of the guitar body 1. The positioning rod 151 is slidably connected within the strip groove 13. The positioning ring 152 is located above the guitar body 1. The sliding string 3 passes through the positioning ring 152 and slidably engages with the positioning ring 152. The sliding string 3 is pressed by the positioning portion 15. By moving the positioning portion 15, different positions of the sliding string 3 can be pressed to achieve different pitches.

[0031] Reference Figure 1 、 Figure 2 and Figure 3A fixing device 4 is installed on the slider 14, which can prevent the slider 14 from contacting the receiving groove 12 when the positioning part 15 is pushed, making it easy to adjust the position of the positioning part 15 to press different positions of the sliding string 3 to achieve different pitches. When there is no need to push the positioning part 15, the slider 14 is pressed against the wall of the receiving groove 12 to position and clamp the positioning part 15. A limiting groove 141 is provided on the upper end surface of the slider 14, and a sliding groove 142 is provided below the limiting groove 141. The width of the sliding groove 142 is greater than the width of the limiting groove 141. The length directions of the limiting groove 141 and the sliding groove 142 are consistent with the length direction of the sliding string 3. Horizontally arranged mounting grooves 143 are provided on both sides of the width direction of the sliding groove 142. The mounting groove 143 is located near the tail of the sliding groove 142. The length direction of the mounting groove 143 is consistent with the width direction of the sliding groove 142. The opposite sides of the two mounting grooves 143 pass through the side wall of the slider 14. Connecting grooves 144 are provided on both sides of the mounting groove 143. The length direction of the connecting groove 144 is consistent with the length direction of the mounting groove 143. The fixing device 4 includes a push block 41, a return spring 42, and a fixed block 43. The lower end of the positioning rod 151 passes through the limiting groove 141 and is fixedly connected to the upper end surface of the push block 41. The positioning rod 151 is slidably connected to the limiting groove 141, and the push block 41 is slidably connected to the slide groove 142. Both sides of the push block 41 and the position near the tail of the guitar are formed with a first inclined surface 411, and both sides of the push block 41 and the position near the head of the guitar are formed with a second inclined surface 412. Reset springs 42 are installed on both sides of the push block 41, and the two ends of the reset spring 42 are fixedly connected to the push block 41. The end of the block 41 and the groove wall of the slide groove 142, the fixed block 43 is slidably connected to the installation groove 143, and the third inclined surface 431 and the fourth inclined surface 432 are respectively formed on both sides of the fixed block 43 and close to the slide groove 142. The third inclined surfaces 431 of the two fixed blocks 43 are respectively matched with the corresponding two first inclined surfaces 411, and the fourth inclined surfaces 432 of the two fixed blocks 43 are respectively matched with the corresponding two second inclined surfaces 412. Through the movement of the push block 41, the two fixed blocks 43 are driven to synchronously approach the slide groove 142 or synchronously move away from the slide groove 142. An elastic component 44 is installed on the slider 14. The elastic component 44 is used to drive the fixed block 43 to return to its original position when not subject to external force. The elastic component 44 includes a connecting block 441 and a tightening spring 442. The connecting block 441 is fixedly installed on the upper end surface of the fixed block 43, and the connecting block 441 is slidably connected to the connecting groove 144. The two ends of the tightening spring 442 are respectively fixedly connected to one side of the connecting block 441 and the groove wall of the connecting groove 144.When the positioning portion 15 is not subjected to external force, the return spring 42 is not subjected to external force, so that the two sides of the push block 41 are respectively pressed against the end faces facing each other of the two fixed blocks 43, and the pressing spring 442 is in a compressed state. The opposite sides of the two fixed blocks 43 are respectively pressed against the two opposite groove walls of the accommodating groove 12, which can increase the friction between the slider 14 and the side wall of the accommodating groove 12, so that the slider 14 is not easy to change its position and maintains the current state. When the relative position of the positioning part 15 and the sliding string 3 needs to be moved, the positioning part 15 can be pushed to move the positioning part 15 along the sliding groove 142 to a position close to one end of the sliding groove 142, thereby driving the pushing block 41 to move to one end of the sliding groove 142, so that one return spring 42 is compressed and the other return spring 42 is stretched. Under the action of the tightening spring 442, the first inclined surface 411 abuts against the third inclined surface 431 or the second inclined surface 412 abuts against the fourth inclined surface 432, so that the connecting block 441 moves along the connecting groove 144 in the direction close to the sliding groove 142, and the two fixing blocks 43 retract into the installation groove 143. The ends of the two fixing blocks 43 that are separated from each other do not conflict with the groove wall of the receiving groove 12, so that the slider 14 can move along the length direction of the receiving groove 12, thereby facilitating the adjustment of the position of the positioning part 15 pressing the sliding string 3 and adjusting the pitch emitted by the sliding string 3.

[0032] Reference Figure 1 and Figure 2 In order to facilitate the adjustment of the tension of the sliding string 3 and thus the pitch produced by plucking the sliding string 3, a string receiving device 5 is installed at the end of the instrument body 1 away from the rocker 2. The string receiving device 5 includes a mounting seat 51, an adjusting post 52, a rotating shaft 53, a worm gear 54, and a worm 55. The mounting seat 51 is a hollow rectangular parallelepiped. The mounting seat 51 is fixedly mounted on the upper end surface of the instrument body 1 and is located at the headstock. The adjusting post 52 is rotatably mounted on the upper end surface of the mounting seat 51. The rotating shaft 53 is vertically fixed to the lower end of the adjusting post 52 and is located within the mounting seat 51. The bottom of the rotating shaft 53 rotatably engages with the inner bottom wall of the mounting seat 51. The worm gear 54 is fixedly mounted on the rotating shaft 53. The worm 55 is rotatably connected to the mounting seat 51 and meshes with the worm 55. One end of the worm 55 passes through the mounting seat 51 and is fixedly mounted with a handle 56. One end of the sliding string 3 is fixed to the side wall of the adjusting post 52. By turning the handle 56, the worm 55 is rotated, and the worm gear 54 meshing with the worm 55 rotates the adjustment post 52, which facilitates the adjustment of the tension of the sliding string 3. The other end of the sliding string 3 is fixed to the rocker 2, and the rocker 2 is fixedly mounted with a resonance box 21. The end of the resonance box 21 away from the rocker 2 is open, and the end of the sliding string 3 connected to the rocker 2 is located within the resonance box 21.

[0033] Reference Figure 2A string guide 57 is mounted on the side of the mounting base 51 near the rocker 2 to guide the sliding string 3. The string guide 57 includes a support rod 571, a string guide ring 572, and a friction-reducing sleeve 573. The support rod 571 is fixedly mounted on the side of the mounting base 51 near the rocker 2. The string guide ring 572 is fixedly mounted on the upper end of the support rod 571. The friction-reducing sleeve 573 is annular and fixed to the inner side wall of the string guide ring 572. It is coaxial with the string guide ring 572, and the extension line of the center of the string guide ring 572 passes through the center of the adjustment column 52. The friction-reducing sleeve 573 can be made of rubber.

[0034] Example 2

[0035] Reference Figure 4 The difference from the first embodiment is that a plucked string 6 is connected between the rocker 2 and the sliding string 3. Specifically, in the embodiment of the present application, there are five plucked strings 6, which are arranged obliquely from bottom to top toward the side close to the rocker 2. A plurality of plucked strings 6 are arranged in parallel along the height direction of the rocker 2, with one end of the plucked string 6 mounted on the rocker 2 and the other end mounted on the sliding string 3. The end of the lowest plucked string 6 connected to the rocker 2 is higher than the end of the sliding string 3 connected to the rocker 2. The connection between the plucked string 6 and the sliding string 3 is located where the sliding string 3 is close to the rocker 2.

[0036] Reference Figure 4 、 Figure 5A plurality of positioning devices 7 arranged at intervals are detachably mounted on the sliding string 3. The positioning device 7 is used to mount one end of the plucked string 6. The positioning device 7 includes a positioning seat 71, a positioning block 72, and a buckle 73. Two elastic clamping pieces 74 are fixedly mounted on the lower end surface of the positioning seat 71. The two clamping pieces 74 are symmetrical about the sliding string 3. The facing sides of the two clamping pieces 74 are arc-shaped and fit with the side wall of the sliding string 3. The two clamping pieces 74 are located below the sliding string 3 and are locked and fixed by fixing bolts 75, so that the positioning seat 71 is fixedly mounted on the sliding string 3. The length direction of the positioning block 72 is consistent with the length direction of the sliding string 3. The positioning block 72 and one side of the positioning seat 71 are hinged by a hinge. The positioning block 72 fits the upper end surface of the positioning seat 71. The positioning block 72 and the positioning seat 71 are fixedly connected by a buckle 73 on the side away from the hinge. A positioning groove 711 is provided on the upper end surface of the positioning seat 71 and the positioning block 72. The positioning groove 711 is arranged along the length direction of the positioning seat 71 and passes through the two end surfaces of the positioning seat 71 or the positioning block 72. The cross-section of the positioning groove 711 is semicircular. One end of the plucked string 6 is located in the positioning groove 711 between the positioning seat 71 and the positioning block 72. The positioning seat 7 1 and the upper end surface of the positioning block 72 are both provided with an isosceles trapezoidal groove 712, the center line of the positioning groove 711 coincides with the symmetry axis of the trapezoidal groove 712, and the shorter bottom side of the trapezoidal groove 712 is close to the tail of the guitar. Two clamping blocks 76 are slidably connected in the trapezoidal groove 712 on the positioning seat 71, and the upper ends of the two clamping blocks 76 are slidably matched with the trapezoidal groove 712 on the positioning block 72. The two clamping blocks 76 are symmetrical about the center line of the positioning groove 711. The two clamping blocks 76 are right-angled trapezoidal blocks. One side of the clamping block 76 perpendicular to the bottom cooperates with the side wall of the sliding string 3, and the height of the clamping block 76 is less than the height of the trapezoidal groove 712. When the plucked string 6 needs to be adjusted, the clasp 73 is unfastened, the positioning block 72 is flipped over so that the positioning block 72 is located on one side of the positioning seat 71, the clamping block 76 is pressed, and the end of the plucked string 6 is dragged to adjust the tension of the plucked string 6. After the adjustment is completed, the positioning block 72 is flipped over so that the positioning block 72 is in contact with the upper end surface of the positioning seat 71, and the clasp 73 is locked so that the positioning block 72 and the positioning seat 71 clamp the plucked string 6. Before the plucked string 6 is plucked, due to the arrangement of the two clamping blocks 76, the two clamping blocks 76 slide along the trapezoidal groove 712 toward the end of the guitar, clamping both sides of the plucked string 6, so that the plucked string 6 is not easily separated from the connection and fixation with the positioning device 7.

[0037] Reference Figure 4 、 Figure 6A plurality of spaced apart clamping devices 8 are installed on one side of the rocker 2. Each clamping device 8 corresponds to the end of a plucked string 6. The other end of the plucked string 6 is fixed to the rocker 2 through the clamping device 8. The clamping device 8 includes a positioning sleeve 81, a movable ring 82, a clamping rod 83, a clamping rod 84, a clamping spring 85, and a driving portion 86. The positioning sleeve 81 is fixedly installed on one side of the rocker 2, and a socket adapted to the end of the plucked string 6 is formed on the end of the positioning sleeve 81 away from the rocker 2. The movable ring 82 is sleeved on the outside of the positioning sleeve 81. A plurality of vertical slots 811 are opened in the circumference of the positioning sleeve 81. The length direction of the vertical slots 811 is consistent with the length direction of the positioning sleeve 81. One end of the clamping rod 83 is hinged to the vertical slot 811. The clamping rod 84 is fixed to one end of the abutting rod 83 close to the inner side of the positioning sleeve 81, and the clamping rod 84 is inclined to the side close to the rocker 2. The end of the clamping rod 84 away from the abutting rod 83 is pressed against the end of the plucked string 6. The two ends of the clamping spring 85 are respectively fixedly connected to the abutting rod 83 and the groove wall of the vertical groove 811, so that the clamping rod 84 is pressed against the side wall of the end of the plucked string 6, and the end of the abutting rod 83 away from the positioning sleeve 81 and the movable ring 82 away from the rocker 2 are pressed against the end of the plucked string 6. One side is fitted and pressed tightly, the driving part 86 is L-shaped, the corner of the driving part 86 is hinged on the rocker 2 and is located on one side of the movable ring 82, the inner side of the driving part 86 is away from the rocker 2, the longer end of the driving part 86 is formed with a pressing plate 861, the pressing plate 861 is arranged along the extension direction of the longer end of the driving part 86, the shorter end of the driving part 86 is formed with a support rod 862, the support rod 862 is fitted and pressed tightly against the side of the movable ring 82 close to the rocker 2, and a plurality of slide rods 87 are fixed on the side of the movable ring 82 close to the rocker 2. One end of 87 is inserted into the rocker 2 and slidably cooperates with the rocker 2. By pressing the pressing plate 861, the pressing plate 861 drives the longer end of the driving portion 86 to move closer to one side of the rocker 2, so that the support rod 862 pushes the movable ring 82 to move away from the rocker 2. The movable ring 82 drives the clamping rod 83 to move along the vertical slot 811 away from the rocker 2, thereby causing one end of the clamping rod 84 to move away from the side wall of the plucked string 6, thereby loosening the clamping of the plucked string 6 and allowing the plucked string 6 to be removed. When it is not necessary to remove the plucked string 6, the elastic force of the clamping spring 85 is large enough to cause the clamping rod 83 to move closer to the vertical slot 811 away from the rocker 2, and the end of the clamping rod 84 is pressed against the side wall of the end of the plucked string 6. A tool with sufficient gravity is required to pry the pressing block, thereby improving the tightness of the installation of the plucked string 6.

[0038] The working principle of the embodiment of the present application is: by moving the slider 14, the positioning part 15 of the pressing sliding string 3 is driven to slide along the length direction of the piano body 1 to change the vibration length of the sliding string 3, thereby emitting sounds of different pitches. The pressing sliding string 3 is a sliding method, which quickly realizes the switching of pitches and can clearly show the transition between sounds.

[0039] Connecting the plucked strings 6 between the rocker 2 and the sliding string 3 enriches the playing style of the plucked instrument, enabling the instrument to produce different sounds and unique plucking techniques. The two ends of the plucked strings 6 can be freely attached to and detached from the rocker 2 and the sliding string 3, significantly enhancing the playing style. When playing the sliding string 3, the five plucked strings 6 can be detached from the sliding string 3. If additional plucked strings 6 are required, the five plucked strings 6 can be attached to the sliding string 3 and the rocker 2. This not only achieves a wide range of tones and a variety of tones, but also enriches the playing style of the plucked strings 6.

[0040] In summary, the present invention adopts both sliding and plucking string playing, thus creating a fusion of different timbres with rich timbre variations, achieving a blend of two different tuning systems, and also achieving a combination of various playing methods, including plucking and sliding. This is both a combination of multiple playing methods and a combination of two different string instrument tuning systems.

[0041] The above is only a preferred specific implementation method of the embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
