Abstract

The utility model relates to a 21-scale keyboard instrument suitable for introductory playing study, comprising a power source, an electronic organ voice chip, a 7-kye keypad, a 3-gear tone switch, and a horn. The 21-scale keyboard instrument is characterized in that when played, five fingers on a right hand can control 7 keys to play 7 scales of Do, Re, Mi, Fa, So, La and Xi, a left hand can operate the 3-gear switch to control three gears of high pitch, alto pitch and low pitch, and altogether 21-scale playing from a low pitch Do to a high pitch Xi cab be completed by ensemble by two hands. The utility model has the advantages of small size and lower cost, conforms to ergonomics requirements, is convenient for beginners to cognize and memorize and ensures that the beginners can be involved in music experience and audition training more easily so as to achieve the purpose of quick start.

Description

A kind of 21 scale keyboard instruments that are suitable for playing the ABC of study

(1) technical field:

The utility model relates to a kind of keyboard instrument of crossing the threshold and learning that is suitable for playing.

(2) background technology:

Along with the development of society and the growth of cultural demand, learning a musical instrument has become raising music attainment, tap intellectual resources, a kind of general phenomenon of cultivating one's taste.Especially for the teenager, at the ABC of learning phase of music, significant to the selection that plays an instrument, general choice keyboard instrument (as piano, fender, mellotron) is as the musical instrument of crossing the threshold on the present market, but this kind musical instrument exists volume bigger, be not easy to carry, the corresponding note identification of fingering exercise and keyboard needs long-term training, learns uninteresting easily.For this reason, Chinese patent 200810116785.3 has the keyboard instrument of Yinyuan marks, sign note present position title on each key, to obtain " key position or finger position information " simultaneously, " note information " be spended time on the note position of understanding musical instrument specially; Chinese patent 200420024276.5 keyboard instruments are played guiding instrument, proposed a kind of key pilot lamp and key one to one mode solve the method for identification keyboard diaphone symbol.Patent 200480019394.X has proposed " not arranging the black key that makes the beginner become estranged keyboard instrument ", to reduce the method for keyboard quantity.But above three's scheme does not all break away from original mellotron structure, and the musical instrument volume is bigger, and keyboard quantity is more, and the corresponding note recognition memory of keyboard is simplified inadequately.

(3) utility model content:

Technical problem to be solved in the utility model provides a kind of keyboard instrument of crossing the threshold and learning that is suitable for playing.

For achieving the above object, the utility model is by the following technical solutions:

A kind of 21 scale keyboard instruments that are suitable for playing the ABC of study, comprise: power supply, mellotron speech chip, 7 key buttons, 3 gear volume control switches, loudspeaker, it is characterized in that: power supply is connected with the mellotron speech chip, 7 key buttons are connected with the mellotron speech chip, 3 gear volume control switches are connected with the mellotron speech chip, and loudspeaker are connected with the mellotron speech chip.

Advantage of the present utility model and effect are: 7 keys of the right hand five finger controls during performance, play Do, Re, Mi, Fa, So, La, 7 scales of Xi, left-handed operation 3 driving switch, control high pitch, middle pitch, bass third gear, two hands are instrumental ensembled can finish bass Do to the high pitch Xi performance of totally 21 scales.Volume is small and exquisite, and cost is lower, meets the ergonomics requirement, is convenient to the cognitive and memory of beginner, makes the beginner can put in the experience, ear-training of music quick start easilier.

(4) description of drawings:

Fig. 1 is the utility model one-piece construction synoptic diagram.Wherein, power supply 1,7

key buttons

2,3 gear volume control switches 3, mellotron speech chip 4, loudspeaker 5.

Fig. 2 is a circuit diagram of the present utility model.

(5) embodiment:

Further set forth a specific embodiment of the present utility model, principle of work below in conjunction with accompanying drawing.

As Fig. 1, power supply 1 is connected with mellotron speech chip 4, and 7 key buttons 2 are connected with

mellotron speech chip

4, and 3 gear volume control switches 3 are connected with mellotron speech chip 4, and loudspeaker 5 are connected with mellotron speech chip 4.

As Fig. 2, power supply :+5V, U1:AM4EA, S1-S7:SMD, SW-3WAY:SMD, LS1:1.6W.
