AI Technical Summary
The existing guqin's soundboard, made of solid wood, results in problems such as insensitive, uneven, and unclear pitch when pressing the strings, making it difficult to improve the evenness and clarity of the pitch while maintaining the amplitude adjustment function.
The soundboard is divided into multiple block structures, with vibration grooves left between adjacent blocks. The top surface of the block can be glued or integrally made onto the soundboard. The hanger is fixed to the back to maintain structural integrity. The contact area between the block and the soundboard is smaller than that of the integral wooden strip.
It improves the vibration efficiency of the soundboard, making the stopped notes more sensitive, bright, and clear, resolving the contradiction between the clarity of the stopped notes and the open notes, without changing the sound production state of the open notes.

Description
TECHNICAL FIELD
[0001] The utility model relates to musical instrument technical field especially relates to a multi -section formula of a qin. BACKGROUND
[0002] The inside of the qin musical instrument has two sound hole cavities (Longchi and Fengzhu) of different sizes, two rectangular wooden strips are respectively fixed in the sound hole cavities of different sizes and are called na Yin, usually the two long wooden strips are integral solid wood, by selecting solid wood of different sizes and materials, the weight and size of na Yin are adjusted to achieve the purpose of adjusting the vibration amplitude of the qin soundboard.
[0003] The main function of na Yin is to adjust the vibration of the scattered sound (open string) and the sound. Because the thickness of na Yin (long wooden strip) is thicker than the thickness of other parts of the soundboard, when the performer presses the string to the upper surface of the body corresponding to na Yin, the whole vibration of the long wooden strip will be caused. The sound of na Yin is not sensitive, uniform and not transparent.
[0004] Therefore, how to maintain the existing adjustment amplitude of the counterweight function of na Yin, destroy its integrity, make the sound of na Yin more sensitive, uniform and transparent, become the technical problem of the personnel in the field to be solved. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims at solving the defects of prior art, and provides a multi -section formula of a qin, which divides the existing integral long wooden strip na Yin, does not reduce its weight and volume, solves the contradiction between the transparency of four string sound and scattered sound. While improving the quality of four string sound, the sound state of scattered sound is not changed.
[0006] The utility model relates to a multi -section formula of a qin, which is fixed on the soundboard of the back of the qin, and the na Yin is a multi -section block structure arranged at intervals, and a vibration groove is arranged between the adjacent two blocks.
[0007] Preferably, the top surface of the block is bonded and fixed or integrally formed on the soundboard of the back of the qin.
[0008] Preferably, a hanging rod is fixed and inserted on the top surface of the block, the top end of the hanging rod is bonded and fixed on the back of the qin, and the projection area of the hanging rod is smaller than the projection area of the block.
[0009] Compared with the related art, the utility model has the following beneficial effects:
[0010] The existing whole structure of the note is characterized in that, no matter at which point the note is pressed, the excited phoneme drives the whole vibration of the whole wood strip; and the multi-section note principle is to divide the whole note wood structure into several small sections. When different phonemes are excited at different points, the vibration is a small range vibration of the "small section" block, so that the vibration efficiency of the sound board is improved, the sound emitted by the pressing of the vibration point is more sensitive, bright and transparent. The pressing of the four strings is improved in quality and improved. Since the design only divides the note, and does not reduce the weight and volume, the contradiction between the transparency and the scattered sound of the pressing of the four strings is solved. While improving the quality of the pressing of the four strings, the sound emitting state of the scattered sound is not changed. BRIEF DESCRIPTION OF DRAWINGS

[0015] The utility model will be further described below in combination with the drawings and embodiments.
[0016] The multi-section note of the guqin of the utility model is fixed on the sound board of the back of the guqin 1, the note is a multi-section block 3 structure arranged at intervals, and a vibration groove 2 is arranged between the adjacent two blocks.
[0017] Preferably, the top surface of the block is bonded and fixed or integrally formed on the sound board of the back of the guqin.
[0018] Preferably, the hanging rod 4 is fixed and inserted on the top surface of the block, the top end of the hanging rod is bonded and fixed on the back of the guqin, and the orthogonal projection area of the hanging rod is smaller than the orthogonal projection area of the block.
[0019] In order to more clearly describe the specific embodiments of the utility model, an embodiment is provided as follows:
[0020] Preferably, the block of the utility model can be hung on the sound board of the back of the guqin by hard materials such as metal rods, metal pins, wood rods and wood pins, which plays a counterweight effect on the sound board, and at the same time, the contact area of the block and the sound board is smaller than that of the one-piece long wood note in the prior art, so as to destroy the integrity of the one-piece long wood note and improve the vibration efficiency of the sound board.
