Description
Technical field
The utility model relates to mellotron field, particularly a kind of children electronic organ.
Background technology
Mellotron, also known as making electronic keyboard, belongs to electronic musical instrument, and range is wider, and harmony enriches, and even can play out an orchestral effect, expressive force is extremely abundant.Because mellotron has abundant tone color, can the various sound of natural imitation circle, and there is the unexistent specific functions of conventional instrument such as automatic rhythm, automatically chord, the children of many curiosities can become interested to it naturally.Children electronic organ is then specially for the electronic musical instrument of child, and structure is simple, and highly little, keyboard is narrow.But children electronic organ function on market is comparatively single, abundant tone color can only be sent, but other are not had to cause the function of child's interest, child play is caused just to be weary of several times, the desire of study can not be triggered, large people are felt simply helpless, has even delayed the age level that child cultivates music sentiment.

It is overcome the deficiencies in the prior art and provide a kind of structure simple children electronic organ that the utility model obtains object, and it can cause child's curiosity, improves child to the interest of music.
The technical scheme that the utility model solves is: a kind of children electronic organ, comprises qin body and is located at the key on qin body; Described key is made up of black key and white key; The side of each white key is provided with at least one first pilot lamp, and the inside of described qin body is provided with controller; Be equipped with the first limit switch in the bottom of each white key, the input end of described controller connects the first limit switch, and the output terminal of controller connects the first pilot lamp.
Further, the left side of described each white key and/or right side are provided with the first pilot lamp.
Further, the side of described each white key is equipped with the first pilot lamp of two different colours.
Further, the surface of each described black key is equipped with the second pilot lamp, the output terminal of described second pilot lamp connection control device.
Further, be equipped with the second limit switch in the bottom of each described black key, the input end of described second limit switch connection control device.
Further, described controller is embedded chip.
The beneficial effects of the utility model: by arranging the first pilot lamp in the side of white key, when child presses key, first pilot lamp is bright, when key sets back, first pilot lamp goes out, thus cause the curiosity of child, improve child to the interest of music, and then utilize music to mould the sentiment of child.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structure enlarged diagram of 1 white key embodiment illustrated in fig. 1.
Embodiment
Embodiment 1
As depicted in figs. 1 and 2: a kind of children electronic organ, the key 2 comprising qin body 1 and be located on qin body 1; Key 2 is made up of black key 22 and white key 21; The right side of each white key 21 is equipped with the first pilot lamp 23 of two different colours; The first limit switch is equipped with in the bottom of each white key 21; The surface of each black key 22 is equipped with second pilot lamp 24, and the bottom of each black key 22 is equipped with the second limit switch; The inside of qin body 1 is provided with controller; The input end of controller connects the first limit switch and the second limit switch, and the output terminal of controller connects the first pilot lamp 23 and the second pilot lamp 24.The controller of the present embodiment adopts the ATmega8 single-chip microcomputer released by atmel corp.
The design concept of the present embodiment is: after opening the master switch of children electronic organ, when child presses some white keys 21, this white key 21 just can touch the first limit switch bottom it, then the first limit switch sends signal to controller, and controller then controls two the first pilot lamp 23 be positioned at inside the key on this white key 21 left side and lights; After this white key 21 sets back, then two the first pilot lamp 23 go out; When child presses some black keys 22, this black key 22 just can touch the second limit switch bottom it, then the second limit switch sends signal to controller, and the second pilot lamp 24 that controller then controls this black key 22 surface is lighted; After this black key 22 sets back, then the second pilot lamp 24 goes out.Due to when not pressing white key 21, first pilot lamp 23 is hidden in the inner side of white key 21, just display when pressing white key 21 and light, thus cause the curiosity of child, trigger the desire of child's study, improve child to the interest of music, and then utilize music to mould the sentiment of child.
