Description
The utility model belongs to a kind of design of fingerboard, relates in order to replace the improvement keyboard that dwindles of standard specification fingerboard.
Modern piano is divided into vertical and two types of triangles.The hammered string instrument tool of piano is made up of keyboard and hammered string instrument, and during performance, finger produces acting force to key, makes key pass to hammered string instrument by the mode that moves up and down, and knocks string by hammered string instrument again and sends beautiful sound.Keyboard is the important component part of hammered string instrument tool, and it goes out key lever and the keyboard frame is formed, and key lever is arranged on the keyboard frame by the location of the pin on the keyboard frame.The two-fold key lever of three sections compositions before, during and after the key lever of grand piano is served as reasons, its leading portion is the key part, and back segment is equipped with the bail that connects with hammered string instrument, and the stage casing is done transition with certain bending degree to front and rear sections and is connected; The key lever of upright piano is single folding key lever of forming by forward and backward two sections, and its leading portion is the key part, and back segment and leading portion form certain bending degree and the bail that connects with hammered string instrument is housed.The keyboard frame mainly rises key lever (key) location and guide effect, and the effect that limits key operating distance (key submergence depth).The keyboard frame of grand piano is the movable part that can separate with base, and the keyboard frame of upright piano generally is screwed on base.
The keyboard width of the piano of standard specification is based on international standard at present, and generally between 13.80mm～14.03mm, 88 key piano key overall width (white key beam overall) are 1215mm～1235mm to its white width of key.Yet in the Asia, women and children are because the restriction of the physiological condition of hand, it is not enough usually to run into octave in study piano process, the performance problems such as difficulty of playing of the first transaction of a day's business chord, influence composer simultaneously and required the music effect of expressing, more there are many diligent piano practicers hand to be practiced the phenomenon of hindering because of hand is little, therefore hand is little is a big misery to a pianist, on the one hand he will pay more than several times of the big people of hand, tens times energy and cost go to practice hard, do not stint and emitting the danger that damages hand, on the other hand, at some professional piano teacher in the eyes, hand means does not for a short time have the future of cultivation, so the little people of hand is subjected to not too fair treatment when the piano of entering oneself for the examination conservatory of music is.Be head it off, past has the people to design and has developed children piano, dwindle by each parts and to finish piano, but existing like this standard piano person must purchase a new piano again, and this thousands of parts are all dwindled and the children piano made, volume is littler than standard piano, thereby this children piano is difficult to promote.
The purpose of this utility model is at the problems referred to above, design a kind of scaled-down version improvement fingerboard, this keyboard can be advantageously used in replacing the fingerboard of standard specification, makes the piano of standard specification increase a kind of function that the little player of hand learns and plays that is suitable for less cost.
Structure of the present utility model, be to be model in order to standard steel piano key board of replacing with it, form by key lever and keyboard frame, key lever is arranged on the keyboard frame by the location of the pin on the keyboard frame, the key lever back segment is equipped with the bail that connects with hammered string instrument, the width that it is characterized in that the key part of each key lever leading portion dwindles in essentially identical ratio, its keyboard overall width is reduced into by 75%～95% of the QWERTY keyboard width of its replacement, the be installed former holding position of nail of the primary standard keyboard key lever back segment that the bail of key lever back segment then remains on its replacement.
Because of the key of key lever leading portion partly comprises two kinds on Bai Jian and black key, the overall width of keyboard is actual to be the overall width of white key.
For improvement keyboard in order to the grand piano keyboard of replacing standard specification, said key lever is the two-fold key lever, the back segment of key lever remains on the former holding position of the primary standard keyboard key lever back segment of its replacement substantially, and the stage casing of key lever is done the transition connection with corresponding bending degree to the leading portion and the back segment of key lever.
For improvement keyboard in order to the upright piano keyboard of replacing standard specification, said key lever is single folding key lever, and the key lever back segment changes the former holding position that primary standard keyboard key lever back segment that the bail that makes on it to be adorned remains on its replacement is installed and follows closely with corresponding bending degree.
Above-mentioned scaled-down version improvement keyboard is relatively independent parts, for the grand piano of standard specification, because the keyboard frame of its former keyboard itself is movable, and therefore can be with the direct mutual alternative of former keyboard of improvement keyboard and standard; For the upright piano of standard specification, after the keyboard frame of the former keyboard of standard and the fixed screw between the base can being unloaded former keyboard is taken out, will improve again in the keyboard replacement.This scaled-down version improvement keyboard is reduced to being suitable for the yardstick that the little player of hand plays with the width of its key part, and the bail that connects with hammered string instrument on its back segment is in the former holding position that the primary standard keyboard key lever back segment that is used to replace is installed and follows closely, thereby can easily scaled-down version be improved keyboard and primary standard keyboard and carry out directly replacing mutually.The octave distance (being equivalent to eight Bai Jian length overalls) of general standard keyboard is about 187～190mm, the opening degree of adult male sex hand is about 180～220mm, the opening degree of adult female's hand is about 160～200mm, the opening degree of children's hand is then littler than the women, apart from reducing about 10～30mm, it is just quite light that women and children play the chord of octave or octave range like this with octave for this scaled-down version improvement keyboard.Simultaneously, the improvement keyboard has kept the usability of QWERTY keyboard, and the player can arbitrarily change as required.The utlity model has dismounting and replace conveniently characteristics attractive in fashion, cheap.
