Abstract
The invention discloses a children electronic organ and belongs to the field of a toy electronic organ. The electronic organ comprises an electronic organ main body, a microcontroller, a data storage unit, and a music switching button disposed at the side portion of the electronic organ main body. The bottom of each key of the electronic organ main body is provided with a microswitch; each key is correspondingly provided with an LED indicating lamp; the music switching button and all the microswitches are connected with the input end of the microcontroller; all the LED indicating lamps are connected with the output end of the microcontroller; and the data storage unit is connected with the microcontroller through an I2C bus. The children electronic organ provided by the invention can automatically guide children to play music through the LED indicating lamps, and improves the children's interest in music.
Description
Technical field
The present invention relates to a kind of children electronic organ, belong to toy electronic music instrument field.
Background technology
In order to cultivate the interest of child to music, a lot of heads of a family can buy some musical toys or musical instrument to child.Yet, because some heads of a family are busy with work, or be subject to the restriction of own level, can not provide enough good music formative education to child, and outside musical instrument teaches the tuition fee of course generally higher now, young child is because learning ability is limited, also and be not suitable for learning instrument, so good musical toy is very important to child.
Toy electronic music instrument is a good musical toy, child just can increase unawares the interest to music and musical instrument when bullet is done, yet current toy electronic music instrument cannot guide child to eject a first complete song, only can freely bring into play formula for child and play, so also lack certain music assisted learning function.
Summary of the invention
The present invention is directed to the problem in background technology, and propose a kind of children electronic organ of playing guiding function that has.
The present invention, for overcoming the above problems, adopts following technical scheme:
A children electronic organ, the melody switching push button that comprises mellotron main body, microcontroller, data storage cell and be located at mellotron main body sidepiece; Bottom at each key of mellotron main body is provided with a microswitch, and each key correspondence is provided with a LED light; Described melody switching push button is all connected with the input end of microcontroller with all microswitches; All LED light are all connected with the output terminal of microcontroller; Described data storage cell is connected with microcontroller by I2C bus.
Preferably, described data storage cell adopts EEPROM.
As scheme optimization, this children electronic organ also comprises a voice module, and described voice module is worked by microprocessor controls.
Technique effect:
1, increase music assisted learning function, can automatically guide child to carry out melody by LED light and play, and then eject complete melody, effectively improved the interest of child to music, alleviated the head of a family's guidance burden.
2, with phonetic function, can when having played melody, child encourage it, further increased child's music learning interest.
3, reasonable in design, successful, has good market outlook.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is circuit structure block diagram of the present invention.
Label title in Fig. 1: 1, mellotron main body; 2, key; 3, microswitch; 4, LED light; 5, melody switching push button.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is done in further detail and is introduced:
Structure of the present invention as shown in Figure 1, the melody switching push button 5 that comprises mellotron main body 1, microcontroller, data storage cell, voice module and be located at mellotron main body 1 sidepiece; In mellotron main body 1, be provided with several keys 2, be provided with a microswitch 3 in the bottom of each key 2, each key 2 is provided with a LED light 4 accordingly.
As shown in Figure 2, melody switching push button 5 is all connected with the signal input part of microcontroller with all microswitches 3 circuit structure of the present invention; Voice module is all connected with the output terminal of microcontroller with all LED light 4; Microswitch 3 under each key 2 connects corresponding LED light 4 by microcontroller; Described data storage cell is connected with microcontroller by I2C bus.
Microcontroller adopts the MSP430F5438A single-chip microcomputer of TI company, and it has nearly 87 I/O mouths, is more conducive to control design; Described data storage cell adopts EEPROM, and after its power down, data can not lost, and for storing music data, and light sequential programme with the LED of the corresponding key of music note; Described voice module is mainly comprised of WT588D speech chip and loudspeaker, for realizing audio-frequency function; LED light 4 adopts red LED lamp, is used to indicate key corresponding to the current note of melody; Microswitch 3 adopts the SS-5GL2 of Omron Corp, when key 2 is pressed, and the normally opened contact of microswitch 3 meeting conducting, and electric signal is passed to microcontroller, microcontroller cuts out corresponding LED by this electric signal; Described melody switching push button 5 adopts self-replaced type button, for melody is switched.
After powering on, microcontroller can be lighted a corresponding LED light by note according to inner melody program, thereby guiding child presses corresponding key.When pressing while lighting the corresponding key of LED, the microswitch of this key bottom can produce electric signal, make microcontroller close the LED that this is lighted, and follow procedure continues to light the LED light of next note (key), be that child only need, according to the order of lighting LED by corresponding key, just can eject a first complete melody.When last note (key) of song has played, microcontroller can send simulated sound by voice module, and child is encouraged.
