For realizing that above-mentioned purpose designs a kind of modified electronics melodica; Comprise qin body, qin body case; Said qin body is installed in the qin body case, and said qin body case flexibly connects outer casing upper cover, and the inside surface of said outer casing upper cover is provided with note and Multi-Function Display; Said note display screen connects qin body integrated circuit through the I/O interface, and it is inner that said qin body integrated circuit is arranged on the qin body.
Said qin body integrated circuit comprises CS, PLC, keyboard scan matrix circuit, D/A change-over circuit, filtering shaping circuit, audio amplifier circuit and loudspeaker; Said CS is arranged on the qin body; Said keyboard scan matrix circuit is installed in the key place of qin body; Said CS, keyboard scan matrix circuit connect PLC by serial equipment, and said PLC output terminal connects display module, D/A change-over circuit respectively, and said D/A change-over circuit connects filtering shaping circuit; Said filtering shaping circuit connects audio amplifier circuit, and said audio amplifier circuit connects loudspeaker.
The power supply of said qin body integrated circuit adopts battery.
Said CS comprises power switch, function button switch.
Said loudspeaker is installed in the two ends of qin body.
The detachable connection qin of said qin body body case.
The outside surface of said qin body case, outer casing upper cover is provided with patterned layer.
The utility model compared with prior art, advantage:
1. the utility model both can have been done the melodica use, can make the mellotron learning aid again and use, but also can play simultaneously, had strengthened the function and the practicality thereof of product greatly;
2. owing to increased the note Presentation Function, the learner can through display screen can accurate cognition to the corresponding note roll call of button on keyboard of controlling oneself, make student's easy master and understanding staff (numbered musical notation) go up the pitch position of roll call.Be convenient to the student and press correct button, understanding staff and this qin function rhythm notion in learning keyboard.Experience the melody and the rhythm of music from vision, sense of touch, the sense of hearing comprehensively, grasp its playing method accurately, the teaching efficiency and the student that improve teacher know general ability;
3. in addition, the utility model can also let the learner know the analog sound of various musical instruments.
