Description
Technical field
The utility model relates to a kind of teaching demonstration device, specifically a kind of apparatus for demonstrating for verifying acoustic resonance phenomenon.
Background technology
Physics is the subject of the most universal law of the research motion of matter and material basic structure.As natural science applied heading discipline, physics research is greatly to universe, and the little forms of motion the most basic to all materials such as elementary particles and rule, therefore become the Research foundation of other each natural branch of sciences.Its theoretical construct makes full use of the working language of mathematics as oneself, and to test the sole criterion as inspection theoretical correctness, it is a current the most accurate natural science subject.Physics research be the most basic characteristics of motion of nature, be a science based on experiment.Experimental teaching is an important step in physics teaching, also be an outstanding weak link, experimental teaching helps student to set up correct concept, grasps scientific law, obtains systematic knowledge, forms skill technique and possess the important means of various ability, but for a long time, due to the impact of exam-oriented education, and to experimental teaching understand deviation and limitation, ubiquity teacher and is taught for " examination ", student learns for " examination ", makes should the have effect of experiment in teaching be difficult to fully demonstrate.How doing experimental teaching well, improve level of experiment teaching, is the problem that numerous Physical Education Teacher are exploring.
Due to the shortage of teaching demonstration teaching aid, being all that simple example example sentence is several to carry out more succinct by adopting for some simple knowledge teachers usually, making student can not visual understanding, reducing learning interest, also reduce the teaching quality of teacher.
Summary of the invention
For the problems referred to above, the utility model provides a kind of apparatus for demonstrating for verifying acoustic resonance phenomenon, improves the learning efficiency of student, vivid, improves the effect of giving lessons of teacher.
For achieving the above object, the technical solution of the utility model is specific as follows:
For verifying an apparatus for demonstrating for acoustic resonance phenomenon, comprise base 1, crane 5, electric cabinet 2, loudspeaker 3, water pond 4; It is characterized in that: described base 1 is arranged crane 5 and electric cabinet 2, described crane 5 arranges water pond 4, and the side of described crane 5 arranges plum blossom knob 6, described electric cabinet 2, its top arranges loudspeaker 3, and the side of described electric cabinet 2 arranges control panel 7.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use, easy to operate, improves work efficiency, improves the learning efficiency of student, vivid, improves the effect of giving lessons of teacher, practical reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1. base, 2. electric cabinet, 3. loudspeaker, 4. water pond, 5. crane, 6. plum blossom knob, 7. control panel.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further described:
For verifying an apparatus for demonstrating for acoustic resonance phenomenon, comprise base 1, crane 5, electric cabinet 2, loudspeaker 3, water pond 4; It is characterized in that: described base 1 is arranged crane 5 and electric cabinet 2, described crane 5 arranges water pond 4, and the side of described crane 5 arranges plum blossom knob 6, described electric cabinet 2, its top arranges loudspeaker 3, and the side of described electric cabinet 2 arranges control panel 7.
The utility model in use, pours appropriate water into by water pond 4, then adjusts the height of crane 5 by turning plum blossom knob 6, then loudspeaker 3 is opened by control panel 7, the volume of control loudspeaker 3, when speaker volume is large, then then can splash spray in water pond 4 simultaneously, its volume is larger, the height of spray is higher, and spray is more, when speaker volume hour, the height that spray then in water pond 4 splashes is low, and spray is also few.
The utility model structure is simple, easy to use, easy to operate, improves work efficiency, improves the learning efficiency of student, vivid, improves the effect of giving lessons of teacher, practical reliable.
