Technical Field
[0001] The utility model belongs to the technical field of erhu, and in particular relates to an erhu auxiliary teaching device. Background Art
[0002] The erhu is a traditional Chinese stringed instrument. The erhu is basically made of wood and consists of basic components such as the neck, sound box, and pegs. The sound box of the erhu has various shapes such as round and hexagonal. One end of the sound box is covered with snake skin or python skin, and the other end is equipped with a carved sound window.
[0003] The existing erhu auxiliary teaching device can only determine the pitch positioning according to the design marked indication data, and can only mark the approximate position, which makes it impossible for the erhu player to press the strings to the precise pitch positioning point, resulting in a lack of flexibility and accuracy in the positioning of the erhu pitch. At the same time, it is also impossible to accurately adjust the erhu bow movement, making it impossible for the erhu player to quickly improve the stability and straightness of the bow movement. Therefore, an erhu auxiliary teaching device is needed to solve the above problems. Utility Model Content
[0004] The purpose of the present invention is to provide an erhu auxiliary teaching device to solve the problems raised in the above background technology.
[0005] The slingshot is actuated by a pair of cam elements, each of which is adapted to move the cam forward and backward, and is configured to move the cam forward and backward, and to move the cam forward and backward, so that the cam forward can move relative to the slingshot, thereby preventing the cam from moving backward.
[0006] By setting the above structure, when it is necessary to accurately position the pitch of the erhu and locate the playing position with accurate pitch, the trapezoidal screw hole slider can be slid to correspond one-to-one with the pitch mark position on the pitch data indicator, thereby realizing flexible adjustment of the erhu pitch. Twisting the fixed threaded ring can position the pitch positioning keyboard to the precise playing position, so that the erhu player can drive the strings to the pitch positioning keyboard to achieve accurate playing of the erhu. When it is necessary to improve the erhu player's bowing level or assist in teaching, the two-way threaded rod is twisted to make the two oblique blocks move closer to or away from each other to adjust the oblique groove space formed between the two oblique blocks. The smaller the oblique groove space is, the more the bow hair on the bow stick can move in a straight line inside the oblique groove, thereby helping the erhu player to improve the stability and straightness of the erhu bowing, thereby helping the erhu player to quickly improve the playing level.
[0007] As a preferred solution, the top of the base is fixedly connected to the bottom of the sound box, and the top of the sound box is provided with a sound bar.
[0008] As a preferred solution, two pegs are provided on the surface of the neck, and strings are provided inside the two pegs.
[0009] As a preferred solution, the two mounting clips are connected to the neck sleeve.
[0010] As a preferred solution, the mounting ring is sleeve-connected to the sound box.
[0011] As a preferred solution, one end of the telescopic rod is fixedly connected to the inside of the mounting collar, and the bidirectional threaded rod is rotatably connected to the mounting collar.
[0012] By setting up a trapezoidal slide, a trapezoidal screw hole slider, a pitch positioning keyboard and an indicator limit plate, the installed trapezoidal slide can provide a limit and guide function for the trapezoidal screw hole slider, so that the trapezoidal screw hole slider can move in the correct direction. At the same time, the design of installing the limit plate higher than the pitch positioning keyboard can provide a limit function for the erhu player and the strings.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] The utility model provides a trapezoidal screw hole slider, a pitch data indicator, a fixed threaded ring, a pitch positioning keyboard, a bidirectional threaded rod and an oblique block. When it is necessary to accurately position the pitch of the erhu and locate the playing position with accurate pitch, the trapezoidal screw hole slider can be slid to correspond one-to-one with the pitch mark position on the pitch data indicator, thereby realizing flexible adjustment of the pitch of the erhu. Turning the fixed threaded ring can position the pitch positioning keyboard to the accurate playing position, so that the erhu player can drive the strings to the pitch positioning keyboard to realize accurate playing of the erhu. When it is necessary to improve the bowing level of the erhu player or assist in teaching, turning the bidirectional threaded rod can make the two oblique blocks move closer to or farther away from each other to adjust the oblique groove space formed between the two oblique blocks. The smaller the oblique groove space is, the more the bow hair on the bow rod can move linearly inside the oblique groove, thereby helping the erhu player to improve the stability and straightness of the erhu bowing, thereby helping the erhu player to quickly improve the playing level.
[0015] The utility model is provided with a trapezoidal slide groove, a trapezoidal screw hole slider, a pitch positioning keyboard and an indicating limit plate.
