Description
Technical field
The utility model relates to the teaching equipment field, relates in particular to moving matchmaker's flash demo integration unit of a kind of multifunctional light and grating net sheet shifter thereof.
Background technology
The development of China's audio-visual education programme cause is starting again from 1978, over nearly 30 years, has experienced three developing stage substantially, i.e. teaching (referring to projector, sound-track engraving apparatus and screen), closed-circuit television teaching and the multimedia teaching of " one act in two machines " entering classrooms.But along with science and technology development because the appearance of computer multi-media, many people think projector out-of-date, fallen behind, should eliminate, and it has been laid aside and neglected, thereby cause serious waste, this is mistaken ideas on instructional media uses.
All be fully used for the audio-visual education programme resource, maximize favourable factors and minimize unfavourable ones, occurred " light moves the matchmaker " technology in recent years, it is that the utilization optical principle produces dynamic effect, and the technology of on various audio-visual education programme medium, using.Through utilization " light move the matchmaker " technology, can on a piece of paper, make high-quality dynamic effect, can analog current flow, the propagation of sound, circulation, absorption of water and the evaporation of blood, the flow process of technology and mechanical motion etc.; Claim to lead formula three-dimensional teaching material, vivid, animation is true to nature; And can on the multimedia teaching facility of televisor, projector, material object display platform etc., use simultaneously; It is spent less, effective, the easy making, has both met national conditions, can realize sharing of audio-visual education programme resource again; Realized createing big as far as possible economic and social benefit with the least possible resource consumption.
Wherein, Chinese patent number discloses the video display appearance dynamic comprehensive device (with reference to Fig. 1) that a kind of application " light moves the matchmaker " technology designs for ZL99240771.0, and it is connected and composed by dynamic spinner and dynamic displacement device jointly.
