In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0031] The utility model discloses a tone-changing thumb zither.
[0032] like Figures 1 to 5 As shown, the tune-changing thumb zither comprises a front cover plate 10, a rear cover plate 20 and strings 30, wherein the front cover plate 10 is fixedly connected to the rear cover plate 20. The strings 30 are fixedly mounted on the front cover plate 10 and the rear cover plate 20, and when a user plucks the strings 30, the box enclosed by the front cover plate 10 and the rear cover plate 20 can produce sounds of various timbres.
[0033] The top of the front cover 10 is provided with a first string fixing mechanism 40 for fixing one end of the string 30, and the bottom is provided with a first string threading mechanism 50 for passing the string 30. The rear cover 20 is provided with a second string fixing mechanism 60 and a second string threading mechanism 70, the second string threading mechanism 70 is used to pass the string 30, and the second string fixing mechanism 60 is used to fix the other end of the string 30. The installation position of the second string threading mechanism 70 is matched with the first string threading mechanism 50, and the second string fixing mechanism 60 is installed on both side edges of the rear cover 20.
[0034] The second string fixing mechanism 60 includes a left string fixing seat 61 and a right string fixing seat 62 which are arranged opposite to each other. The left string fixing seat 61 is provided with a first mounting groove 611, and the right string fixing seat 62 is provided with a second mounting groove 621. The left string fixing seat 61 fixes the other end of the string 30 through the first mounting groove 611, and the right string fixing seat 62 fixes the other end of the string 30 through the second mounting groove 621.
[0035] Since there are many strings 30, the left string holder 61 and the right string holder 62 can cooperate with each other to fix the other ends of the strings 30. For example, if there are 17 strings 30, the left string holder 61 can be used to fix the other ends of 9 of the strings 30, and the right string holder 62 can be used to fix the other ends of the other 8 strings 30. Through the cooperation between the left string holder 61 and the right string holder 62, the user can play conveniently.
[0036] The above-mentioned tone-changing thumb zither includes a front cover, a rear cover and strings. The front cover is fixedly connected to the rear cover. A first string-fixing mechanism for fixing one end of the string is installed on the top of the front cover, and a first string-threading mechanism for matching the string to pass through is installed on the bottom; a second string-fixing mechanism and a second string-threading mechanism are installed on the rear cover, the second string-threading mechanism is used to match the string to pass through, and the second string-fixing mechanism is used to fix the other end of the string; the installation position of the second string-threading mechanism is matched with the first string-threading mechanism, and the second string-fixing mechanism is installed on the two side edges of the rear cover. When the user plays, one hand plucks the strings on the side of the front cover, and the other hand presses the strings on the side of the rear cover to achieve the tone-changing effect. Since the second string-fixing mechanism is installed on the two side edges of the rear cover, the strings on the side of the rear cover are close to the two side edges of the rear cover, and the user can achieve tone-changing by extending the other hand to the edge of the rear cover without extending to the middle of the rear cover, thereby reducing the movement amplitude of the user's hand and improving the user's experience.
[0037] The left string holder 61 is fixedly connected to the rear cover plate 20 by a first screw, and the right string holder 62 is fixedly connected to the rear cover plate 20 by a second screw. The left string holder 61 and the right string holder 62 are fixedly connected to the rear cover plate 20 respectively, so that the structure of the variable tone thumb zither is more stable.
[0038] The first string fixing mechanism 40 includes a nut 41, an adjusting screw 42 rotatably connected to the nut 41, and a string fixing hook 43 threadedly connected to the adjusting screw 42. The string fixing hook 43 is used to fix one end of the string 30, and the adjusting screw 42 is used to drive the string fixing hook 43 to perform linear motion by rotation, thereby adjusting the tightness of the string 30. The string fixing hook 43 is sleeved on the adjusting screw 42, and when the adjusting screw 42 rotates in the opposite direction, the string fixing hook 43 can perform linear motion in the opposite direction, thereby tightening the string 30 or loosening the string 30. Through the cooperation between the string fixing hook 43 and the adjusting screw 42, the user can conveniently adjust the tightness of the string 30.
[0039] Furthermore, the tuned thumb zither further includes a tuning key 80 detachably mounted on the top of the front cover 10, and the tuning key 80 is used to drive the adjusting screw 42 to rotate. When the user needs to adjust the tightness of the strings 30, the tuning key 80 can be conveniently removed from the top of the front cover 10 for adjustment. After the adjustment is completed, the tuning key 80 can be conveniently installed on the top of the front cover 10.
[0040] The front cover plate 10 is fixedly connected to the nut 41 by a third screw. The front cover plate 10 is fixedly connected to the nut 41, so that the structure of the tone-changing thumb zither is more stable.
[0041] The first string-threading mechanism 50 includes a first string-threading seat 51, and the first string-threading seat 51 is provided with a first string-threading hole 511 for the string 30 to pass through. The second string-threading mechanism 70 includes a second string-threading seat 71, and the second string-threading seat 71 is provided with a second string-threading hole 711 for the string 30 to pass through. The string 30 passes through the first string-threading hole 511 into the box enclosed by the front cover plate 10 and the rear cover plate 20, and passes through the second string-threading hole 711 out of the box enclosed by the front cover plate 10 and the rear cover plate 20, so that the vibration of the string 30 can form sounds of various timbres inside the box, so as to facilitate the user to play.
[0042] Furthermore, the user can adjust the shapes of the first string seat 51 and the second string seat 71 according to actual needs. Preferably, the first string seat 51 and the second string seat 71 are both arc-shaped.
[0043] Furthermore, in order to facilitate the box body formed by the front cover plate 10 and the rear cover plate 20 to emit sound outward, a sound outlet hole 11 is provided in the middle of the front cover plate 10, and the sound outlet hole 11 is circular.
[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
