Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument structures, in particular to the intonation of an erhu. Background Art

[0002] As is known, the erhu is a traditional Chinese stringed instrument. It originated in the Tang Dynasty and was originally called the huqin. In modern times, it was renamed the erhu and began to develop vigorously. To learn the erhu, 80% of the effort is in intonation. In order to solve the intonation problem of students, many predecessors have thought of many auxiliary methods, but none of them have completely solved the problem of students' scale practice. Because the erhu does not have fixed scale frets, and the left hand has to change up and down, it is difficult to form the action memory of pressing the correct pitch. The known erhu intonation auxiliary indicators include piano post pitch stickers, cylindrical pitch locators, and patented erhu pitch calibrators. However, since the existing auxiliary technologies generally contain only one fixed pitch scale, they can only fit one effective string length, and the effective string length of different people varies greatly, the pitch position is not the same, the higher the pitch, the greater the pitch difference, and the pitch scale is far away from the strings, and accurate calibration cannot be performed by the naked eye. In addition, although the patented erhu pitch corrector can be flexibly moved according to the effective string length to find the accurate pitch, and is close to the strings when viewed from the side, it is still very far away from the strings when viewed from the front. The eyes are looking down at an angle, and the accurate pitch on the strings cannot be seen at all. The fingers move back and forth along the strings and the rod. When changing positions, the fingers slide up and down quickly in the direction of the strings. Moreover, the plastic sheet that marks the pitch is fixed, blocking the fingers from moving up and down and resisting the fingers from rubbing the strings.

[0003] Therefore, some erhu learners have practiced for decades but still cannot find the pitch accurately, and the performance effect cannot achieve the ideal effect, which greatly wastes time and energy and increases the cost of learning. In summary, there is an urgent need for a tuning device that can solve the above technical problems and can be used for practicing and playing erhu. Utility Model Content

[0004] The utility model provides a tuning device which can be used for practicing and playing erhu, and is used to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tuning device that can be used for practicing and playing the erhu, which is arranged on the sound box and the sound bar, and the tuning device includes a fixed upper end, a metal sheet, a quality bar, a spring and a fixed lower end, and the quality bar is provided with a sound column and a column base. The fixed upper end is fixedly connected to the sound bar, the fixed lower end is fixedly connected to the sound bar, the metal sheet is connected to the fixed upper end through a thin shaft, one end of the quality bar is connected to the metal sheet, and the other end of the quality bar is connected to the fixed lower end through a spring and a thin shaft.

[0006] In a preferred embodiment, the sound column and the sound column base are connected as one body.

[0007] In a preferred embodiment, the sound column includes outer ends of the stylus fingers, and the outer ends of the stylus fingers are kept in the same straight line.

[0008] In a preferred embodiment, the fixed upper end and the fixed lower end are respectively provided with two rows of small circular holes for inserting the shaft.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] First, the sound post can be moved and fixed to the exact position of each scale according to different erhu, so it can adapt to all erhu;

[0011] Second, the outer end of the sound post is close to the plane of the two strings when viewed from the side. The left side is close to the inner string when viewed from the front, and the right side is close to the outer string. The outer end of the sound post points accurately, and the position of each accurate scale can be seen accurately.

[0012] Third, when playing the erhu, the fingertips can directly touch the outer end of the sound post, and you can feel whether you have pressed the correct pitch, whether it is too high or too low, and how far the difference is without looking.

[0013] Fourth, the bases of the sound posts are all fixed on the same flat hard-surface strip which is parallel to the plane where the two strings are located when the sound posts are stationary. When the fingers press on each sound post strip, the whole sound post moves towards the neck of the guitar, increasing the distance between the outer ends of other sound posts and the strings, so that the strings will not be touched.

[0014] Fifth, the sound post is elastically movable between the strings and the neck, and two rows are arranged on both sides of the inner and outer strings. The two rows of sound posts and the post base form a groove, and the two strings can be pressed down without touching the sound post and the post base. The device neither hinders the movement of fingers up and down, nor affects the normal string vibrato action.

[0015] Sixth, the setting of the sound post and the column base. The double post or single post with the sound post and column base integrated can be assembled to form the quality of various keys (D, F, G, A, etc.); the sound post can also be installed and removed from the column base, or the sound post and column base can be fixed according to the semitone relationship, and you can freely combine them into the required tuning according to your needs; you can also make a hole every semitone on the quality strip according to the determined length based on the effective string length of 36 to 42 cm, and you can fix the column base and sound post on the corresponding hole according to your needs to combine the required tuning.

[0031] In addition, holes can be drilled on the rigid flat strip that fixes the sound column base 5 according to the position of semitone relationship based on the actual limited string length of the erhu, and the required scale holes can be selected according to the needs to directly install the integrated or split sound column base 5. The combined sound column can be set according to actual requirements.

[0032] In some embodiments, the sound column 4 includes a stylus outer end 401, and the stylus outer end 401 is kept in the same straight line.

[0033] Specifically, the outer end 401 of the sound post 4 is kept in the same plane and arranged close to the strings on both sides of the inner and outer strings, close to the two strings but not reaching them, and there is enough vertical space between the inner and outer sound posts 4, so that the sound post 4, the sound post base 5, and the fret bar 303 will not touch the two strings when vibrato is played.

[0034] In some embodiments, two rows of small circular holes 6 for inserting shafts are provided on the fixed upper end 301 and the fixed lower end 305 .

[0035] Specifically, two rows of small circular holes 6 for inserting shafts are provided at the fixed upper end 301 and the fixed lower end 305. Different circular holes can be selected for connecting metal sheets 302 and springs 304 for erhu used by different people, so that the outer end plane of the sound post 4 can be adjusted to the most suitable position with a distance from the two strings.
