The purpose of this utility model is a kind of musical instrument teaching display of design, will demonstrate and listen sound and light prompt to combine coaching person, can also see fingering and note when hearing sound, makes to have effect visual in image, that teach through lively activities.
Musical instrument teaching display of the present utility model comprises display box, key switch and printing opacity teaching card, it is characterized in that:
Described key switch is arranged on blowing instrument sound hole top or keyboard instrument button one side;
Be provided with in the described display box display box is separated into the dividing plate of note display room and the display circuit that is connected and composed by rectifier power source, bulb, battery, in each note display room bulb and battery are set in pairs, bulb one end also connects the rectifier power source anode, bulb other end tap key switch one end, described battery is divided into two groups, battery parallel connection in the group, two Battery packs are connected in series, the positive termination rectifier power source anode of first group of batteries in parallel connection, the negative terminal of second group of batteries in parallel connection also connects the described key switch other end and rectifier power source negative terminal;
Described printing opacity teaching card is arranged on the display box face, and note is corresponding with described note display room upper-lower position on the teaching card.
Be fixed with iron bar on the described teaching card, be provided with magnet piece in the described display box.
Be provided with press-button type switch in the line of the described bulb other end and described key switch one end.
To the different musical instruments and the melody of different ranges, the teacher can be by changing position, transposing teaching card and the adjustment snap fastener switch of key switch on musical instrument, make and show that note is consistent with the actual note of playing wind instruments or playing, when teacher modeling is played wind instruments or is played, press the key switch simultaneously, connect the power circuit of corresponding bulb in the display box, bulb is bright to be that the note display room is bright, the student can see by the suggested fingering of teaching card, note intuitively and hear sound, can obviously improve teaching efficiency.
There is the musical instrument teaching display of 13 note display rooms (can satisfy the range of general melody) to further specify technology of the present utility model below in conjunction with a design.
Fig. 1 is a musical instrument teaching display electrical schematic diagram;
Fig. 2 is that F transfers recorder teaching card structure synoptic diagram;
Fig. 3 falls B to transfer recorder teaching card structure synoptic diagram;
Fig. 4 is that C transfers recorder teaching card structure synoptic diagram;
Fig. 5 is a mouth organ teaching card structure synoptic diagram.
Referring to Fig. 1. K1-K13 is arranged on the key switch of blowing instrument such as recorder sound hole top or is arranged on shoegaze such as the key switch of accordion key one side among the figure, can move the position on musical instrument with the melody range.Battery E1-E13 and bulb L1-L13 are arranged in pairs in each note display room of display box, and E1-E6 also connects, and E7-E13 also connects, and are attempted by on the rectifier power source after the two Battery packs serial connection again.J1-J13 is a snap fastener switch, and K1-K13 arbitrarily is connected with L1-L13, and K is a battery main switch.Press method of attachment among the figure, L1 was bright when K1 was closed, and L2 was bright when K2 was closed ... and the like.The batteries in parallel connection group is set is and increase load capacity when pressing several key at the same time.
Referring to Fig. 2 to Fig. 4, can be when recorder is imparted knowledge to students by being arranged on the break-make of the key switch on the recorder, corresponding bulb light on and off are imparted knowledge to students in the control display box, Fig. 2 F extremely shown in Figure 4 transfers, falls the B accent and C transfers the teaching card can select to use, be attached on the display box (iron bar and magnet piece), the student can directly see fingering, the note of playing wind instruments that recorder is played wind instruments and hear the sound of playing wind instruments from the teaching card.
Referring to Fig. 5, when mouth organ is imparted knowledge to students can according to the range of melody select the basic, normal, high position of teaching card corresponding with display box with the teaching sticker on display box, be arranged on the keyboard (as accordion) according to the mouth organ scale then, find the relevant position and carry out wire jumper to connect, make the keyboard pronunciation identical with mouth organ scale teaching card with snap fastener switch.Also note on the teaching card can be imposed different colors during enforcement, representative is blown as redness, and blue expression is air-breathing, and teaching efficiency is better.
Also can utilize this teaching display to carry out music theory teaching, as make c major scale teaching card or A minor scale teaching card is affixed on respectively on the display box,, just can carry out sound, light teaching again by the corresponding connection of snap fastener switch with the key switch; And for example carry out bat teaching, can be on the teaching card respectively with ruddiness represent by force, blue light is a little less than representing etc.
The utility model is simple in structure, but flexible combination adapting to the teaching of different musical instruments, different melodies, sound, light are easy to the student and receive grasp, and can increase students'interest in learning in conjunction with the teaching visual pattern, teaching efficiency is good.
