CN2932551Y - Grouping col type dulcimer of identical string length - Google Patents

Abstract

The utility model belongs to an equal chord length grouping mountain pass type dulcimer, wherein the dulcimer uses the mountain pass to divide into several sections, and each section of the mountain pass is arranged to parallelize with each other and also parallelize with tone code corresponding to a supporting string. The utility model has the advantages that the strings of the pronunciation sections have the equal length, symmetrical force and the same tension; the pronunciation board of the dulcimer surface has a symmetrical pressure, thus resonating to be even; and the strings have an accurate and concentrative pronunciation, convenient for adjusting and not easy to loose.

Description

Etc. chord length grouping mountain pass formula dulcimer

Technical field

The utility model belongs to a kind of dulcimer musical instrument.

Background technology

As depicted in figs. 1 and 2, in the market or the structure of the qin body of the Yang Qin in using be to fix two scroll heads 4 at the two ends of the curved two qins group of one side, establish veneer in two qins groups and two scroll heads and sound beam upper surface and form qin face soundboard 7, the space formation resonant tank 2 of qin face soundboard lower end.Promptly two scroll head plates upper end is installed with string post 6 on qin face soundboard both sides, and the rolling plate 5 of two scroll head plates of string post inboard is provided with a straight column type mountain pass 1, and its effect is to hold string.Draw between the two string posts and be provided with string 3, the string of voiced segments must be positioned on the mountain pass, also is provided with the sound sign indicating number between every string and the qin face soundboard, and the sound sign indicating number supports 9 by sound sign indicating number seat 8 and the string that supports string and forms.The string of section is the string voiced segments between mountain pass and string support.The pronunciation of Yang Qin is to make it produce vibration by knock the string voiced segments with hammer, and will vibrate and import qin face soundboard by the sound sign indicating number and resonant tank is produced resonate, and a pitch is made up of 2～5 strings usually.Because the mountain pass is the oblique setting of qin face according to trapezoidal shape, must cause the different length of string of section between mountain pass and string support, therefore cause every string unbalance stress of same pitch, the tension force difference, cause qin face soundboard pressurized inequality, it is uneven to produce resonance, string cacoepy and unconcentrated, the difficulty of tuning a stringed instrument and easy loose string.

Summary of the invention

The purpose of this utility model is design chord length grouping such as an a kind of mountain pass formula dulcimer, makes the string equal length of voiced segments, and it is stressed evenly to have a string, tension force is identical, and qin face soundboard pressurized is even, produces resonance evenly, the string pronunciation is accurate and concentrate the advantage of tune a stringed instrument simple and convenient and difficult loose string.For this reason, the utility model adopts the mountain pass to be divided into several sections, every section mountain pass setting parallel to each other, and every section mountain pass be arranged in parallel with the sound sign indicating number of corresponding support string.The said structure design has realized the purpose of this utility model.

The utility model has the advantages that the string equal length that makes voiced segments, it is stressed evenly to have string, tension force is identical, also having the range expansion distributes in order, enlarge the string part distance, simplify structure, remove the bridge sign indicating number of mixed and disorderly setting basically, reduce system qin cost significantly, also have the advantage of being convenient to play.

Embodiment

As shown in Figure 1 to Figure 3, oneself described in detail in background technology for the structural representation of traditional dulcimer for Fig. 1 and Fig. 2, so be not repeated.The utility model is that the mountain pass structure of traditional dulcimer is improved.As shown in Figure 3, chord length grouping such as a kind of mountain pass formula dulcimer, by scroll head, string and sound sign indicating number are formed.The mountain pass is divided into several sections, forms every section grouping mountain pass 10, every section mountain pass setting parallel to each other, and every section mountain pass be arranged in parallel with the sound sign indicating number of corresponding support string.

Described every section mountain pass is positioned at mountain pass seat 12 upper ends, and protrudes seat upper surface, mountain pass.The string of section such as is at chord length string 11 voiced segments between every section mountain pass and string support.Obviously, the utility model makes every string equal length of a pitch, and it is stressed evenly to have a string, and tension force is identical, and qin face soundboard pressurized is even, produces resonance evenly, and the string pronunciation is accurate and concentrate the feature of tune a stringed instrument simple and convenient and difficult loose string.

In a word, the utility model makes the string equal length of voiced segments, and it is stressed evenly to have a string, and tension force is identical, and qin face soundboard pressurized is even, produces resonance evenly, and the string pronunciation is accurate and concentrate, and the advantage of tune a stringed instrument simple and convenient and difficult loose string can be promoted the use of.

Claims (2)

1, chord length grouping such as a kind of mountain pass formula dulcimer, by scroll head, string and sound sign indicating number are formed, and it is characterized in that: the mountain pass is divided into several sections, every section mountain pass setting parallel to each other, every section mountain pass be arranged in parallel with the corresponding sound sign indicating number that supports string.

2, by chord lengths such as claim 1 is described grouping mountain pass formula dulcimer, it is characterized in that: described every section mountain pass is positioned at seat upper end, mountain pass, and protrudes seat upper surface, mountain pass.
