Abstract

The utility model discloses an LED (light-emitting diode) flashing piano convenient to learn, comprising a piano body, a power supply module, a singlechip and LED lattice modules, wherein the quantity of the LED lattice modules is equal to that of piano keys of the piano body; each LED lattice module is arranged inside each piano key; the LED lattice modules are connected with the singlechip; the power supply module is connected with the singlechip to supply electricity to the singlechip; and the power supply module and the singlechip are arranged inside the piano keys. According to the LED flashing piano, key mapping and techniques of a player are prompted by displaying numbers through the LED lattice modules arranged on the piano keys, so that the player can independently practice under the absence of guide of a teacher. Therefore, the LED flashing piano is simple in structure and worthy of promotion.

Description

A kind of ease-to-learn LED luminous piano that glimmers

Technical field

The utility model relates to the piano technical field of structures, refers to utilize the luminous next piano that performance is pointed out or corrected of flicker of LED lamp especially.

Background technology

Piano is liked owing to its tone color grace is subjected to increasing people, existing Piano Teaching all is that the piano academics and students imparts knowledge to students one to one, but the big expense not enough and engagement piano teacher of piano teacher resource all makes the pianophile that the study piano is hung back, therefore need a kind of piano that can under the situation of not engaging the piano teacher, can independently practise badly, help the piano study person to improve.

The utility model content

The purpose of this utility model provides a kind of built-in disposal system of utilizing, and music score is encoded, and the LED lamp is installed in each key, changes the performance of key into LED in proper order by control software and lights order, the piano that the pianist is pointed out.

The utility model is that the technical scheme that its technical matters of solution adopts is:

A kind of ease-to-learn LED luminous piano that glimmers, it is characterized in that: comprise piano, power module, single-chip microcomputer, LED lattice module, described LED lattice module quantity equates with piano key quantity, the LED lattice module is arranged within each key, the LED lattice module links to each other with single-chip microcomputer, power module and single-chip microcomputer are connected to single-chip microcomputer and power, and power module and single-chip microcomputer are arranged on piano inside.

As further specifying, described LED lattice module is arranged on the middle part of key.

As further specifying, described single-chip microcomputer is connected with display screen, is used for showing music score.

As further specifying, described key comprises foundation trench, LED lattice module, key skin and printing opacity acrylic board, and the LED lattice module is installed in the foundation trench, covers the printing opacity acrylic board at the LED lattice module, and covers the key skin in other zones.

As further specifying, described LED lattice module adopts double-colored 8 * 8LED dot matrix display module.

As further specifying, described LED lattice module quantity is 88 or 61.

As further specifying, described power module connects attaching plug, adopts civil power to power.

The utility model will be encoded to each note according to the correct situation of playing for the music score of teaching, and be stored in the single-chip microcomputer, when the teaching beginning, according to the corresponding concrete key of note and play used finger, information is presented on the LED lattice module of concrete key, after the player pressed this key, system was according to music score and play and require automatically the finger of the required key of pressing of the next one and employing to be pointed out at the LED of this key lattice module.In the practice, adopt different colours to point out to the right-hand man, and concrete finger adopts digital prompt, for example according to music score and play the fingering that requires note that next needs play and employing when pressing the do sound for the left hand thumb right hand forefinger press the 1a sound, this moment, the key in do sound correspondence showed red numeral " 1 ", and simultaneously in the key blue numeral of demonstration " 2 " of 1a sound correspondence, the player is pointed out.The utility model utilization is arranged on LED lattice module on the key and shows that numeral comes the player is carried out the key position and gimmick is pointed out, and the player is independently practised under the guidance that does not have teacher, and is simple in structure, be worthy to be popularized.

Description of drawings

Fig. 1 is one group of key external structure of the utility model embodiment piano figure.

Fig. 2 is the utility model embodiment piano key internal structural map.

Fig. 3 is the structured flowchart of the utility model embodiment piano.

Label among the figure is: 21, the white key of piano; 22, piano black key; 23, foundation trench; 24, LED lattice module; 25, printing opacity acrylic board; 26, key skin.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.

In conjunction with Fig. 1 and Fig. 2, medium position on the white key 21 of the utility model embodiment piano and the piano black key 22, be provided with LED lattice module 24, LED lattice module 24 adopts double-colored 8 * 8LED dot matrix display module, be used for showing the numeral of different colours, textural, LED lattice module 21 is installed in the foundation trench 23, on foundation trench 23, cover key skin 26 again, and in key skin 26 positions of LED lattice module 24 correspondences, covering be printing opacity acrylic board 25, printing opacity acrylic board 25 has certain rigidity, finger presses LED lattice module 24 when avoiding playing, the serviceable life of prolongation LED lattice module 24.LED lattice module 24 is arranged under each key, and namely when key quantity was 88, the quantity of LED lattice module 24 also was 88; When key quantity was 61, the quantity of LED lattice module 24 also was 61.

In conjunction with Fig. 3, the utility model embodiment power module links to each other with single-chip microcomputer, for single-chip microcomputer and total system are powered, single-chip microcomputer links to each other with the LED lattice module, color and numeral that control LED lattice module shows, and be convenient music score and the various operational order of showing, also being provided with display, display is connected on the single-chip microcomputer.

In the practice, set prompting color that left hand plays for red, the right hand is played the color of prompting for blue, and thumb, forefinger, middle finger, the third finger, little finger of toe use numeral " 1,2,3,4,5 " to point out respectively.If according to music score and play the fingering that requires note that next needs play and employing when pressing the do sound for the left hand thumb right hand forefinger press the 1a sound, this moment, the key in do sound correspondence showed red numeral " 1 ", and simultaneously in the key blue numeral of demonstration " 2 " of 1a sound correspondence, the player is pointed out.

The utility model utilization is arranged on LED lattice module on the key and shows that numeral comes the player is carried out the key position and gimmick is pointed out, and the player is independently practised under the guidance that does not have teacher, and is simple in structure, be worthy to be popularized.
