Abstract

The utility model relates to an improved electronic melodica which comprises a melodica body and a melodica body housing. The melodica body is arranged in the melodica body housing. The melodica body housing is movably connected with a housing upper cover. The inner surface of the housing upper cover is provided with notes and a multifunctional display screen. The display screen is connected with a melodica body integrated circuit via an I\O interface. The melodica body integrated circuit is arranged inside the melodica body. A conventional melodica and a conventional electronic organ are combined to be the electronic melodica of the utility model, thereby enhancing the practicality. Besides, a note display function is added, so that as a music learning beginner, the student can see roll calls on the display screen simultaneously while the student is pressing keys on the keyboard of the electronic melodica by hands. Therefore, the student can easily know that the position of each key is the roll call of the note, and also can conveniently remember the roll call and the pitch of each key of the C major on the keyboard. Moreover, the improved electronic melodica enables the beginner to easily remember the roll calls and identify the position of each roll call on the keyboard during a preliminary stage, and allows the beginner to grasp the playing method of the keyboard accurately, thereby improving the teaching effect and saving the music teaching time.

Description

A kind of modified electronics melodica

[technical field]

The utility model relates to the musical instrument technical field, specifically a kind of modified electronics melodica.

[background technology]

At present, traditional melodica, mellotron are separate musical instrument.Learn simultaneously or play when needs, will melodica, mellotron all 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 playing method accurately class hour to the student, thereby also influences the music teaching effect.

[summary of the invention]

The purpose of the utility model is exactly will solve above-mentioned deficiency and a kind of modified electronics melodica is provided; Existing melodica, mellotron are united two into one; The function and the practicality thereof of product have been strengthened greatly; But also increased the note Presentation Function; As long as on electronics melodica keyboard, just can see the roll call on the display screen in the hand button, the position of being convenient to be familiar with button was exactly the roll call of this note, is convenient to remember the roll call and the pitch of each key of c major on keyboard when the student was begun to learn music.Can make the beginner begin to learn roll call of very easy understanding and keyboard position in the time in stage, 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.It is big blank to have filled up one in the Chinese music teaching field.

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.
