Abstract

The utility model belongs to the technical field of the accordion manufacturing, relating to the technology of the right-hand musical performance apparatus, the connection technology between key levers, etc. Through changing a right-hand piano-typed keyboard into a key button, changing the original major second arrangement to the minor third arranged, and causing the first row of tone and the second row of tone in the basic tone area to be provided with an interlock auxiliary key button respectively, an auxiliary tone area is formed. The utility model has the advantages that while in playing, the fingering method is simple, the key pitch is short, the utility model has the homophony malposition playing convenience of the auxiliary tone area. The utility model can be matched with a left-hand free bass mechanism to make the left hand structure and the right hand structure to be uniform, the trend of fingering method to be consistent to reduce the matching and coordinating difficulty of both hands.

Description

Key knob formula accordion

The utility model belongs to accordion manufacturing technology field, relates to technology such as connect between right hand music performance apparatus, the key lever.

The accordion of domestic production at present is that the right hand is the accordion of piano key disc type entirely, and left hand adds the bass machine of chord type for the single system bass.This is very backward accordion.Also some producer had had a fling at some small-sized key knob qins in recent years.As: the accordion of three row's knobs that little bass key knob qin that musical instrument company in Tianjin does and Shanghai accordion factory do etc. all belongs to the accordion or the jejune structural design of toy formula.

Lacking of piano-accordion mainly is:

The first, because black key height, Bai Jian are low, can bring many performance obstacles to the player during performance.Arrange performances when playing changing, must accurately remember various combination between the white-black key and the desired various fingering of various modes or the like, make the player feel very difficulty.

The second, because the width of one group of sound of right hand keyboard is 14 centimetres, often make player's finger stretch directly excessively, children's hand particularly, even can't reach octave at all.Cause the finger stiff, can't correctly play.

Three, because the left hand bass is arranged by five degree, and right hand keyboard is by arranging twice, this two big system architecture is far different, makes right-hand man's fingering move towards inconsistent, causes the difficulty of player's both hands matching coordinative very big.

In addition,,, can't enter regular classroom, carry out education activities because function imperfection, structure are immature as little bass key knob accordion or three row's key knob accordions.The accordion of three row's knobs can be played, but difficulty is very big in the fingering design.

The purpose of this utility model is by changing the performance mechanism of the right hand, the piano-style keyboard is changed into the key knob, original arrangement twice being become minor third arrange.And make first row in the basic range of sound and the collateral key knob that second sound of arranging all has an interlock, form an auxiliary range of sound.

Further specify below in conjunction with accompanying drawing:

Fig. 1 is panel and phoneme Pareto diagram.

Fig. 2 is key knob, the section of structure of key lever in the qin chamber.

Fig. 3 is seat and a side view at the bottom of the key lever.

Fig. 4 is the wire hole figure of qin bottom.

Among the figure: 1, the interval of vertically facing two key knobs mutually up and down: minor third.2, the basic range of sound.3, the auxiliary range of sound.4, panel.5, first row's key knob.6, second row's key knob.7, basic key knob.8, auxiliary key knob.9, extension spring is prominent colludes.10, extension spring.11, qin chamber section.12, C shape iron wire.13, auxiliary key bar.14, basic announcement key lever.15, key lever elbow.16, seat at the bottom of the key lever.17, the next silk of wearing.18, the upper silk of wearing.19, seat wire hole at the bottom of the key lever.20, qin body bottom wire hole.21, panel hole.

The utility model is by panel (4), basic key knob (7), auxiliary key knob (8), base Seat (16) forms at the bottom of this key bar (14), auxiliary key bar (13), extension spring (10), the key bar The accordion right hand is played mechanism. Its right hand music performance apparatus is with a kind of button with hollow cylindrical body Serve as the key knob (7) of shape, (8). Its sound order is to press vertically to face mutually up and down two key knob minor thirds (1) Arrange. First row key knob (5), each sound of second row key knob (6) in the basic range of sound (2) wherein There is a company to move the key knob, consists of an auxiliary range of sound (3). The key bar (13) in the auxiliary range of sound is Be connected to form by a C shape iron wire (12) and basic key bar (14) and move.

The utility model is implemented by following process: seat (16) at the bottom of the key bar is used wood screw Parallel being fixed in the qin chamber (11). Bore two wire holes (20) and seat at the bottom of the key bar in qin body bottom Two wire holes (19) corresponding. The sound order that provides according to Fig. 1 is then arranged successively, with base This key bar (14) is put on the next silk (17) of wearing successively, and adjusts. Treat that basic key bar wears After complete, the lower end of extension spring (10) hung in that the extension spring on the end seat is prominent collude on (9). To assist again Key bar (13) is put on by corresponding seat with the upper silk (18) of wearing, and with C shape iron wire (12) two The right angle collude and penetrate in the hole that these two kinds of key bars accomplish fluently in advance, as connecting device. Make basic sound Key bar (14) forms to connect with auxiliary key bar (13) and moves. After treating that all key bars have been worn, with panel (4) Be buckled in key bar upper end and fix it. Corresponding key bar elbow (15) is stretched out in panel hole (21), After key knob (7), (8) be inserted on the elbow (15) of key bar be glued.

Advantage of the present utility model is: fingering is simple during performance: 24 big minor scales can be finished with a fingering.Bond length is short: the bond length between one group of sound has only 9 centimetres wide.Have that the unisonance dystopy in the auxiliary range of sound plays just, make fingering more flexibly, convenient.Can also be supporting with left hand free bass bass mechanism, make right-hand man's structure unified, it is consistent that fingering is moved towards, and reduces the difficulty of both hands matching coordinative.
