Abstract

The utility model relates to a teaching appliance, which solves problems of difficult remember, difficult learning and deficient relevant teaching aids of a staff. The utility model is composed of a display part, a control part and connecting conductors. The utility model is characterized in that the display part is a rectangular flat sheet, and the control part is a sliver-shaped flat sheet. The display part is provided with key display patterns and staff-graph display patterns taking mini lamps as indicator lamps. The control part is provided with a transitional keystroke device which is fixed by corresponding to a keyboard and is connected with corresponding indicator lamps by conductors organically. When a user knocks a certain key of the keyboard to strum music, an indicator lamp of key display patterns is correspondingly lighted. Simultaneously, an indicator lamp of the staff-graph display patterns is lighted. The utility model is visual and conspicuous, and can raise interests for teaching.

Description

Staff teaching aid

The utility model relates to instruments used for education, refers to the staff teaching appliance that a kind of pea lamp shows especially.

Mostly music lover, learner feel that used staff has the point image small tadpole, too bad difficult note; In the teaching of classroom staff, teacher just utilizes blackboard or wall chart, several groups of staff figure draw, lecture to the student, about relation and knowledge between the line on the line spectrum, what lean on is that the student memorize mechanicallys, and learns very uninteresting, aspect music teaching, Shang Weijian has simple and practical staff instruments used for education.

The purpose of this utility model is to provide a kind of staff aided education instrument that is used for music teaching.

The purpose of this utility model is achieved in that staff aided education instrument, formed by display part and actuating element and connection lead thereof, it is characterized in that the display part is the rectangle plain film that is provided with suspender, in the plain film front, the below of suspender is provided with button display pattern and two groups staff figure display pattern intuitively, and display pattern all is light source and as pilot lamp with the pea lamp; Be provided with the connection lead in the plain film inboard, connect the pilot lamp that lead organically connects each diverse location; Actuating element is the corresponding fixing strip plain film with keyboard in position that is placed on mellotron or the keyboards such as piano or organ, this plain film with insulcrete as base plate, to tie up copper coin is circuit link, and on insulcrete, be provided with the through hole that matches with keyboard, in through hole, be provided with and the contacted transition keystroke of key device, transition keystroke device is divided into the long and short two kind, divide and adopt long and short two kind rivet type metal construction in addition, its top can contact with corresponding lead, constitute contact-making switch, when keystroke, connect corresponding lead, otherwise be in off-state; Place the long keystroke device that is of Bai Jianshang; Place on the black key for short punch key device.

As above design, in use, no matter press as any key on the mellotron, just can on the button display pattern, light corresponding pilot lamp in the display part, meanwhile, on staff figure display pattern, also light corresponding pilot lamp, demonstrate the position place of certain sound on staff figure, come into plain view, very directly perceived.

The utility model is described in further detail with drawings and Examples more below:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model electronic-circuit diagram.

Fig. 3 is the utility model actuating element partial schematic sectional view.

Mark among the figure: 1. display part, 2. actuating element is 3. tied up copper coin, 4. through hole, 5. insulcrete, 6. long keystroke device, 7. short punch key device, 10. plain film, 11. suspenders, 12. plain film, 13. button display patterns, 14,15. staff figure display patterns, 16. connection lead, 17. rectifier, 18. attaching plugs, 9,19,20,21. pilot lamp.

As shown in the figure: staff aided education instrument, by display part 1 and actuating element 2 and connect lead 16 and formed, it is characterized in that display part 1 is for being provided with the rectangle plain film 12 of suspender 11, in plain film 12 fronts, the below of suspender 11 is provided with button display pattern 13 and two groups staff figure display pattern 14,15 intuitively, and display pattern all is light source and as pilot lamp 9,19,20,21 with the pea lamp; Be provided with connection lead 16 in plain film 12 inboards, connect the pilot lamp 9,19,20,21 that lead organically connects each diverse location; Actuating element 2 is for being placed on the corresponding fixing strip plain film 10 with keyboard in position on mellotron or the keyboards such as piano or organ, this plain film 10 with insulcrete 5 as base plate, to tie up copper coin 3 is circuit link, and on insulcrete 5, be provided with the through hole 4 that matches with keyboard, in through hole 4, be provided with and the contacted transition keystroke of key device, transition keystroke device is divided into the long and short two kind, adopt long and short two kind rivet type metal construction respectively, its top can contact with corresponding lead, constitute contact-making switch, when keystroke, connect corresponding lead, otherwise be in off-state; Place the long keystroke device 6 that is of Bai Jianshang; Place on the black key for short punch key device 7.As shown in Figure 1: it is characterized in that the pilot lamp 20,21 on the button display pattern 13 is corresponding one by one mutually with pilot lamp 9,19 on the staff figure display pattern 14,15, be pilot lamp on certain button display pattern 13 when bright, the indication on the staff figure display pattern 14,15 corresponding with it is also bright; And on staff figure display pattern 14,15, represent the sharp mark with red led; Represent the flat mark with blue indicator light, surplus is the natural light pilot lamp.The utility model can also have additional the music beat device in addition, to increase interest, strengthens timing.The utility model is adopted 6～9 volts of direct currents by attaching plug 18 through rectifier 17 when adopting 220 volts of AC power; Without alternating current the time, can battery operation, power consumption is little.Can hang on the blackboard or on the wall, eye-catching attractive in appearance, simple and practical, be a kind of exceedingly useful Music teaching aid.
