Description
Technical field
The utility model relates to a kind of music teaching aid, refers more particularly to a kind of music teaching exercise qin.
Background technology
Mellotron has long history as musical instrument a kind of in musical performance, its cardinal principle is for making pronunciation device send a corresponding musical sound by pressing key, but memory music score is a very loaded down with trivial details and uninteresting process, student needs by constantly practising being improved, the Method compare of instruction in drill practice is single, but the exercise of time easily causes attention of student to decline, and affects teaching efficiency.
Utility model content
The purpose of this utility model is just to provide to solve the problem that a kind of structure is simple, the music teaching of the key memory degree that improves practitioner practises qin
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises mellotron body, microprocessor, local storage, speech player, A/D converter and LED light, described mellotron body is provided with key, the front correspondence of described key is provided with multiple described LED light, the output terminal of described key is connected with the input end of described A/D converter, the output terminal of described A/D converter is connected with the input end of described microprocessor, the FPDP of described microprocessor is connected with the FPDP of described local storage, the output terminal of described microprocessor is connected with the input end of described speech player, described microprocessor-based control output terminal is connected with the control input end of multiple described LED light respectively.
Particularly, described music teaching exercise qin also comprises usb circuit, and the output terminal of described usb circuit is connected with the input end of described microprocessor.
Further, the rear of described key is provided with anti-skid rubber cushion.
Particularly, described speech player is two.
The beneficial effects of the utility model are:
The utility model, by the corresponding LED light being arranged on key front, reminds the position of the correct key of practitioner, and structure is simple, improves student to key degree of memory, vivid and interesting, improves enthusiasm and the teaching efficiency of the study music score of student.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structured flowchart of the present utility model;
In figure: 1-speech player, 2-key, 3-LED pilot lamp, 4-mellotron body, 5-usb circuit, 6-anti-skid rubber cushion.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises mellotron body 4, microprocessor, local storage, speech player 1, A/D converter and LED light 3, mellotron body 4 is provided with key 2, the front correspondence of key 2 is provided with multiple LED light 3, the output terminal of key 2 is connected with the input end of A/D converter, the output terminal of A/D converter is connected with the input end of microprocessor, the FPDP of microprocessor is connected with the FPDP of local storage, the output terminal of microprocessor is connected with the input end of speech player 1, microprocessor-based control output terminal is connected with the control input end of multiple LED light 3 respectively.
Music teaching exercise qin also comprises usb circuit 5, the output terminal of usb circuit 5 is connected with the input end of microprocessor, can upgrade the content of local storage at any time, the rear of key 2 is provided with anti-skid rubber cushion 6, increases comfort level time student plays.
In the present embodiment, speech player 1 is two, the playing effect of mellotron can be improved, simulate stereosonic environment, teacher can by the music score that pre-sets by usb circuit 5 input end local storage, after the effect of microprocessor is that music score is resolved into continuous print note, the LED light 3 controlling key 2 correspondence is luminous, after student can only press corresponding key 2, just can jump into the next note played, otherwise LED light 3 can not be extinguished, the LED light 3 in key 2 front is arranged on by correspondence, remind the position of the correct key of practitioner, structure is simple, improve student to key 2 degree of memory, vivid and interesting, improve enthusiasm and the teaching efficiency of the study music score of student.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
