Abstract

The utility model discloses a music electronic teaching board, which comprises an electronic piano and a music theory electronic-teaching board. An area of staff is arranged on the front side of the music theory electronic-teaching board. A corresponding group of indicators are fixedly arranged on the corresponding position of the staff. A fixed sliding scale groove reflecting the corresponding relationship of musical scale and musical interval or chord music is opened in the area of the staff adjacent to the front side of the music theory electronic-teaching board. An area of keys is arranged at the front side of the music theory electronic-teaching board and a hand-touching inductive polar plate is arranged at the position of each key. The various music theories are integrated and skillfully combined by the utility model, which has a strong visibility and the link between each music theory is strong. The intervention of the sliding scale is the link to contact between each music theory, and the relationship between each music theory can be easily grasped by the sliding scale. The utility model is easy to learn and understand for the teaching of the music theory, and has simple operation.

Description

The music electronic demonstrator

Technical field

The utility model relates to a kind of Music teaching aid.

Background technology

Traditional single happy teaching often can only be adopted the general audio-visual education program board of teacher's pointer formula five lines, this audio-visual education program board can be integrated or the music theory knowledge kind of demonstration less, lecture and the mode of demonstration music theory single, visual poor, contiguity is not strong between each music theory, is not easy to the student and grasps relation between various music theorys.

Summary of the invention

Problems such as the purpose of this utility model provides a kind of music electronic teaching board, and the instruction basic music theory knowledge kind that exists with dissatisfied music audio-visual education program board of determining traditional is few, and visual difference and teaching efficiency are undesirable.

The composition of music electronic demonstrator described in the utility model comprises: mellotron and music theory audio-visual education program board two parts of being made up of circuit of electronic organ, function control circuit, display circuit, audio power amplifying circuit and loudspeaker; Be provided with the staff table section in music theory audio-visual education program board front, have one group of corresponding pilot lamp to distribute respectively and be fixed on the correspondence position of above-mentioned staff table; At the positive adjacent staff table section of music theory audio-visual education program board place, have the fixedly slide scale groove of a reflection scale interval or chord music corresponding relation; Also be provided with the key zone in music theory audio-visual education program board front, be equipped with hand on the position of each key and touch the induction type pole plate; One group of output terminal that the hand of one group of key of described representative touches the induction type pole plate connects the correspondence reason dish signal input part of circuit of electronic organ respectively by a gate matrix circuit, the hand of one group of key of described representative touches the induction type pole plate and also realizes that by amplifying circuit controlling and driving is connected with the representative scale interval of staff table section or the pilot lamp of chord symbol respectively.

Aforesaid music electronic demonstrator, hand wherein touch the induction type pole plate and select the induction installation that realize to produce induced signal by principle of induction or contact principle for use

Music electronic teaching board described in the utility model can integrated staff demonstration, keyboard, accent name, tone mark, musical alphabet, slide scale be in interior multi-functional combination, can lecture staff, transfer name, tone mark, modified tone, musical alphabet, scale, interval, chord, note, body to end multiple basic music theory knowledge such as symbol, keyboard, beat, also can restrain the demonstration and the research of system.This device is integrated with multiple music theory knowledge, dexterously it organically is linked together, and is visual strong, and contiguity is strong between each music theory, and the intervention of slide rule is the tie of getting in touch between each music theory, can grasp relation between various music theorys easily by slide rule.This device is to the music theory teaching easily-learned easily mastered, and is easy and simple to handle.

Description of drawings

Fig. 1 is the example structure figure in teaching board of the present utility model front.

Fig. 2 is circuit theory pivot figure of the present utility model.

Fig. 3 is the amplifying circuit schematic diagram of driving pilot lamp of the present utility model.

Fig. 4 is the embodiment circuit diagram of the hand of the present utility model connected mode of touching induction type pole plate and circuit of electronic organ.

Embodiment

Teaching board structure of the present utility model is referring to Fig. 1, one can horizontal or the plate face 6 of suspension on, be provided with staff table 2, mellotron or fingerboard 4, reflection musical sound relation by the correspondence coupling the slide scale 3 that is linked together of conversion rule.Described staff table is provided with one group of pilot lamp 1 of representing different scales.Described keyboard 4 adopts some induction type electrode plate structures to represent one group of keyboard respectively.Described slide scale 3 is that the groove structure by the plate face carries out activity and pegs graft and change.Slide scale 3 comprises scales such as scale interval or chord.Control panel 5 parts of primary electron qin also are arranged on the teaching board front.

Circuit bank prejudice Fig. 2 of this teaching board, one group of output terminal representing the hand of one group of key to touch the induction type pole plate is connected with the corresponding keyboard signal input part of circuit of electronic organ by a gate matrix circuit respectively.One group of output terminal that described hand touches the induction type pole plate also respectively with the staff table on corresponding pilot lamp connect by amplifying circuit, and provide the trigger pip of pilot lamp for it.The circuit structure of amplifying circuit is wherein seen Fig. 3.One group of output terminal that hand touches the induction type pole plate and the corresponding keyboard signal input part ways of connecting of circuit of electronic organ can adopt the form of Fig. 4, and what Fig. 4 adopted is that one group of analog switch is realized the connection between them.

Touch the key of playing the musical instrument with hand and can send beautiful music as playing mellotron or steel, bright the opening of light of relevant position on the staff table expressed the correspondence position of this key on staff simultaneously.

The markings of " scale slide rule " are aimed in 15 kinds of tone marks any one, transfer the scale relation on keyboard corresponding with the roll call scale of numbered musical notation " 1,2,3 ... " expression and this on the slide rule.Otherwise, arbitrary key is aimed in the numbered musical notation roll call " 1 " on the slide rule, can on keyboard, find corresponding scale Rankine-Hugoniot relations according to numbered musical notation " 1,2,3 ... ", and the tone mark aimed at of the markings on the slide rule is the tone mark of this scale and transfers name.

The root sound markings of " interval slide rule " are aimed at arbitrary key on the keyboard, and the interval sign from the slide rule can be found out on the keyboard interval relation in the octave, as two degree, pure four degree .... or the like.

The root sound markings of " chord slide rule " are aimed at arbitrary key, and the chord sign from slide rule can find out that several chords commonly used close the position that ties up on the keyboard.

This audio-visual education program board is applicable to the teaching scope from child's formative education to the large spans such as music theory research of university, as the Music teaching aid of kindergarten, middle and primary schools for suitable.Also be applicable to social education, as the study class of various instrumental musics or vocal music, training class etc.
