Abstract
The invention relates to a photoelectric music demonstration apparatus. The apparatus is characterized in that: the apparatus comprises a pedestal which is in a shape of a hui character; a power supply, a switch and a music player are arranged in the pedestal; the power supply, the switch and the music player are connected through leads to form a loop; an inner surface of an upper end of the pedestal is provided with a plurality of photoelectric sensing emitters which are directed downward; the inner surface of an lower end is correspondingly provided with a photoelectric sensing receiver which is directed upward; the photoelectric sensing emitters and the photoelectric sensing receiver are connected with the music player through the leads. Compared to the prior art, structure of the invention is simple and the apparatus is cheap to produce. Through demonstration, connection between light, electricity and sound can be specifically, visually and intuitively understood by students who are in growth stage and in primary schools and kindergartens.
Description
Technical field
The present invention relates to a kind of teaching aid, particularly a kind of photoelectricity music apparatus for demonstrating.
Background technology
For the ease of visualize teaching, need various teaching aids to demonstrate various scientific phenomenas at present.Teaching aid is to propagate the material object of science and technology, the artificial purpose of education, is scientific and technological completely medium, is indispensable equipment in teenager's scientific and technological activities.The teaching aid of using in the scientific and technological activities has object visual and duplicate teaching aid.Teaching aid can also be divided into demonstration usefulness and practice is operated with two kinds.
The most theoretical property of teaching aid of demonstrating resonance phenomenon is stronger at present, but lacks intuitive, does not belong to audiovisual aids.Audiovisual aids can make that knowledge is specialized, imagery, for student's perception, understanding and memory Knowledge Creation condition.Intuitively can impel student's concrete perception to combine, reduce the difficulty that the student grasps abstract concept, help it to form clear and definite notion, develop its observation ability and thinking ability, improve students'interest in learning and enthusiasm with abstract thinking.
The teenager is with keen interest with the phenomenon that electricity is produced for light at present, but special shortage can ocular demonstration light in the reality, the apparatus for demonstrating of electricity and sound, make current student particularly at present also just the primary school of stage of development and the student of kindergarten can not be specifically, vivid, understand many principless of science by instrument intuitively.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, low cost and by demonstration allow the primary school that also is in the stage of development and the student of kindergarten can both be specifically, image, understand the photoelectricity music apparatus for demonstrating of the contact of light, electricity and sound intuitively.
For solving the problems of the technologies described above, described photoelectricity music apparatus for demonstrating, comprise a base 1 that returns type, this base 1 inside is provided with power supply, switch and music player, described power supply, switch and music player are linked to be the loop by lead, it is characterized in that: on the inside surface of the upper end of described base 1, be provided with a plurality of directions photoelectric sensing transmitter 3 down, be provided with a photoelectric sensing receiver 4 that is directed upwardly on the inside surface of lower end accordingly, described photoelectric sensing transmitter 3 is connected described music player with photoelectric sensing receiver 4 by lead.
On the outside surface of described base 1, also be provided with a control knob 5, the break-make of the described switch of these control knob 5 controls.
Also be provided with a qin tool model 2 in the upper end of described base 1.
Photoelectricity music apparatus for demonstrating of the present invention is provided with a plurality of directions photoelectric sensing transmitter 3 down on the inside surface of the upper end of described base 1, be provided with a photoelectric sensing receiver 4 that is directed upwardly on the inside surface of lower end accordingly, described photoelectric sensing transmitter 3 is connected described music player with photoelectric sensing receiver 4 by lead.When fingering a stringed instrument with hand, the light that photoelectric sensing transmitter 3 sends has been lived in stick shift, thereby photoelectric sensing receiver 4 does not have light to inject, and makes music player send sound of musical instrument.For primary school that is in the stage of development and the student of kindergarten, photoelectricity music apparatus for demonstrating does not have the string can sounding yet, and is very magical, can improve the interest of their study, strengthens the desire of learning science knowledge.
Compared with prior art, the present invention has the following advantages:
1, intuitive.Audiovisual aids can make that knowledge is specialized, imagery, for student's perception, understanding and memory Knowledge Creation condition.Intuitively can impel student's concrete perception to combine, reduce the difficulty that the student grasps abstract concept, help it to form clear and definite notion, develop its observation ability and thinking ability, improve students'interest in learning and enthusiasm with abstract thinking.
2, typicalness.The typicalness of audiovisual aids makes it meet the teaching requirement, can form presentation clearly and guiding student get on to be familiar with things from the phenomenon of showing essence effectively.Rise to conceptual knowledge from perceptual knowledge, promote that the student profoundly grasps knowledge comprehensively.
Description of drawings
Fig. 1 is the structural representation of photoelectricity music apparatus for demonstrating of the present invention.
