At present, traditional melodica, mellotron are separate musical instrument.Learn simultaneously or play when needs, melodica, mellotron all will be with, so use, carry very inconvenient.In addition, existing melodica does not all have the prompting of mellotron and note Presentation Function etc. on the qin body, and this just can't grasp its accurately playing method class hour to the student, thereby also affects the music teaching effect.
[summary of the invention]
Purpose of the present invention is exactly will solve above-mentioned deficiency and a kind of electronics/melodica with Presentation Function is provided, existing melodica, mellotron are united two into one, function and the practicality thereof of product have greatly been strengthened, but also increased the note Presentation Function, when being begun to learn music, the student needs only the roll call that when the electronic melodica keyboard is with the hand button, just can see on the display screen, the position of being convenient to be familiar with button is exactly the roll call of this note, is convenient to remember roll call and the pitch of each key of c major on keyboard.Can make the beginner begin to learn the roll call of very easy understanding and keyboard position in the phases-time, and can accurately grasp the playing method of keyboard, thereby improve teaching efficiency, save the music teaching time, also be the dual-purpose desirable learning aid of a qin.Filled up one in the Chinese music teaching field large blank.
Design for achieving the above object a kind of multi-functional electronics/melodica of demonstration that has, comprise qin body, qin body case, described qin body is installed in the qin body case, described qin body case is flexibly connected outer casing upper cover, the inside surface of described outer casing upper cover is provided with note and Multi-Function Display, described note display screen connects qin body integrated circuit by the I/O interface, and it is inner that described qin body integrated circuit is arranged on the qin body.
Described qin body integrated circuit comprises gauge tap, PLC, the keyboard scan matrix circuit, the D/A change-over circuit, filtering shaping circuit, audio amplifier circuit and loudspeaker, described gauge tap is arranged on the qin body, described keyboard scan matrix circuit is installed in the key place of qin body, described gauge tap, the keyboard scan matrix circuit connects PLC by serial equipment, described PLC output terminal connects respectively display module, the D/A change-over circuit, described D/A change-over circuit connects filtering shaping circuit, described filtering shaping circuit connects audio amplifier circuit, and described audio amplifier circuit connects loudspeaker.
The power acquisition battery of described qin body integrated circuit.
Described gauge tap comprises power switch, function button switch.
Described loudspeaker is installed in the two ends of qin body.
The detachable connection qin of described qin body body case.
The outside surface of described qin body case, outer casing upper cover is provided with patterned layer.
The present invention compared with prior art, advantage:
1. the present invention both can do the melodica use, can make again the mellotron learning aid and use, but also can play simultaneously, had greatly strengthened function and the practicality thereof of product;
2. owing to having increased the note Presentation Function, the learner can recognize the own note roll call that button is corresponding on keyboard accurately by display screen, makes the student easily grasp and be familiar with the pitch position of the upper roll call of staff (numbered musical notation).Be convenient to the student and press correct button, understanding staff and this qin function rhythm concept in learning keyboard.Experience melody and the rhythm of music from vision, sense of touch, the sense of hearing comprehensively, grasp its accurately playing method, the teaching efficiency and the student that improve teacher know general ability;
3. in addition, the present invention can also allow the learner know the analog sound of various musical instruments.
