Description

Roller bearing silk column inductive dulcimer

Technical Field

The utility model belongs to a roller bearing silk pole sums up formula dulcimer.

Background

As shown in fig. 1, the structures of the currently marketed or used yangqin, which are already standardized as 402-type dulcimer, are: the periphery of the piano face soundboard 7 is integrally bonded with the upper part of the side wall of the frame body 4 of the corresponding part, and the lower end face of the piano face soundboard and the upper end faces of the middle beam, the plurality of longitudinal beams and the two cross beams of the corresponding part which are fixed in the frame body are integrally bonded. The upper end face both sides of the frame body are equipped with headstock apron 1, are equipped with roller board 6 on the frame body of headstock apron inboard, and fastening string device is located the frame body up end of both sides, is equipped with several low, the tone code base 3 of high pitch from the left side top of headstock soundboard to the right side below of headstock soundboard in proper order, corresponds pronunciation string on the tone code base and is equipped with several tone code post 31. Two ends of each string 5 are respectively fixed on the corresponding fastening string devices and are supported by the upper ends of the corresponding rollers 2 on the roller plate and the upper ends of the corresponding sound code columns. A piano surface soundboard of the dulcimer is provided with a plurality of groups of strings with different timbres in parallel from top to bottom, and each group of strings consists of four strings, namely high, secondary high, middle and low tones.

When playing a musical instrument, the musical instrument bamboo is used for knocking the strings at the sound code, and the strings vibrate to enable the vibration waves to pass through the sound code column and the sound code base to be inducted into the musical instrument face soundboard for resonance and sound production. The roller bearing position of traditional dulcimer on the roller board is put in disorder, and the position on the roller board all is single use, and is complicated during the operation, and because the length of single roller bearing differs, the string drops from the roller bearing easily, also inconvenient operation during the tuning.

Disclosure of Invention

The utility model aims at designing a roller bearing silk pole induction type dulcimer, overcoming the not enough of traditional dulcimer roller bearing, having structural design rationally, convenient operation ties the string tuning easily, and the tuning is simple and convenient, difficult string loosening, the advantage of easy fixed string.

Therefore, the utility model relates to a roller bearing silk post sums up formula dulcimer comprises frame body, headstock apron, roller bearing, roller board, musical instrument face soundboard and string. The roller plate is simultaneously provided with a roller and a roller screw column, and the roller screw column supporting the same group of strings and the code base where the code column is located are arranged in parallel. Three strings of inferior high, well, bass in every group string be located the roller bearing silk post, the high pitch string is located the roller bearing. The rolling shaft wire column is a cylinder with the diameter of 5-8 mm. The length of the rolling shaft wire column is 10-35 mm. The rolling shaft wire column is provided with a groove for fixing the string. The rolling shaft wire column and the rolling shaft are made of the same material.

Above-mentioned structural design has realized the utility model discloses a purpose.

The utility model overcomes the not enough of traditional dulcimer roller bearing has structural design rationally, convenient operation, ties the string tuning easily, and the tuning is simple and convenient, difficult string loosening, the advantage of easy fixed string.

Detailed Description

As shown in fig. 1 to 5, the general structure of the present invention is the same as the general structure related to the background art except for the rolling shaft wire column, and therefore, the description thereof will not be repeated.

A roll shaft wire column inductive dulcimer is composed of a frame body 4, a piano head cover plate 1, a roll shaft 2, a roll shaft plate 6, a piano surface sound board 7 and strings 5. The roller plate is simultaneously provided with a roller 2 and a roller screw column 8. The rolling shaft screw columns supporting the same group of strings and the phonetic code base 3 where the phonetic code column 31 is arranged are parallel to each other. Three strings of inferior high, well, bass in every group string be located the roller bearing silk post, the high pitch string is located the roller bearing.

The rolling shaft wire column is a cylinder with the diameter of 5-8 mm. The length of the rolling shaft wire column is 10-35 mm. The roller bearing silk column can be the cylinder, and three strings of inferior high, well sound, bass in same group's string are located the roller bearing silk column, and this group's high pitch string is located traditional roller bearing.

The roller bearing silk column also can be the roller bearing silk column on be equipped with the recess 81 of fixed string, three strings of inferior high, mediant, bass in the same group of string are located the three recess that is interval distance distribution on the roller bearing silk column to make things convenient for each string that corresponds to fix in it. The rolling shaft wire column and the rolling shaft are made of the same material.

The utility model discloses a roller bearing silk pole is former dispersion solitary inferior height, in, the unified replacement of the three roller bearing of bass is a roller bearing silk pole, and the top holds with a set of inferior height, in, the roller bearing silk pole and the mutual parallel arrangement at code post place (as shown in figure 5 inferior zhongyin base 32) of bass string, make the effective chord length equidistance between every group string from code post to the roller bearing silk pole, and make every group string atress even, tension is unanimous, thereby the musical instrument face soundboard atress that makes is even, stress balance, the operation of using has been made things convenient for promptly, string tuning is tied easily again, it is simple and convenient to transfer the string, and be difficult for the pine string, because the length extension of roller bearing silk pole, the string also can not fall from the top.

Other structures and processes of the utility model are the same as the traditional structure, so the description is not repeated.

In a word, the utility model overcomes the not enough of traditional dulcimer roller bearing, it is reasonable to have a structural design, convenient operation, ties the string tuning easily, and the string tuning is simple and convenient, and the advantage of difficult string loosening, easy fixed string can use widely.
