Abstract
The utility model relates to an teaching aid, specifically to a resonance demonstration apparatus, including a knocking drum served as a vibration source and a vibration accepting drum for receiving the vibration, wherein the knocking drum and the vibration accepting drum are arranged on a same horizontal plane in the opposite direction, the knocking drum and the vibration accepting drum are composed of a cylinder annular metal drum support and a striking drum surface provided on one end of the drum support, the drum support is supported at a supporting seat by an upper and a lower bracing columns; a pellet is suspended on the external side of the striking drum surface of the vibration accepting drum. The resonance demonstration apparatus of the utility model generates vibration by striking the knocking drum, the vibration is transmitted to the vibration accepting drum having the identical natural frequency with the knocking drum, so that the vibration accepting drum also starts the vibration, and the wooden and metal accessory suspended pellets will jump up themselves. Therefore the resonance is visually demonstrated, so that the students in the developmental stage in the elementary schools and nursery schools can particularly, visually and intuitively understand the resonance through the demonstration.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of resonance effect 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 the material object of propagating science and technology, the artificial purpose of education, is scientific and technological medium completely, 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.
Resonance is meant that a physical system under characteristic frequency, does the situation of vibration with peak swing.This characteristic frequency is referred to as resonant frequency.There are many places that the phenomenon of resonance is arranged in the nature.The mankind also utilize in its technology or attempt to avoid covibration.The example of some resonance is such as having: the orbit resonance between the satellite of the acoustic resonance of musical instrument, some Jovian planets of the solar system, the resonance of the basilar memebrane in the animal ear, resonance of circuit or the like.The most theoretical property of teaching aid of demonstrating resonance phenomenon is stronger at present, but lacks intuitive, does not belong to audio-visual aids.Audio-visual aids can make specific knowledge, visualization, for student's perception, understanding and memory Knowledge Creation condition.Intuitively can impel student's concrete perception to combine with abstract thinking, reduce the difficulty of students abstract concept, help it to form clear and definite concept, develop its observation ability and thinking ability, improve student's learning interest and enthusiasm.The apparatus for demonstrating that special shortage can the ocular demonstration covibration in the reality, so that current student can not be specifically, image, understand the presentation process of covibration by apparatus for demonstrating intuitively, particularly at present also just primary school and the student of kindergarten of stage of development, do not have the resonance demonstration apparatus directly perceived just can not the intuitivism apprehension covibration.
Summary of the invention
The technical problems to be solved in the utility model 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 be specifically, image, understand the resonance effect apparatus for demonstrating of resonance effect intuitively.
For solving the problems of the technologies described above, described resonance effect apparatus for demonstrating, comprise one serve as vibration source knock drum 3 and the passive drum 4 that shaken that is shaken, the described drum 3 that knocks is arranged at same surface level with the drum 4 that shaken, be and be provided with in opposite directions and both at least one apart rice, it is characterized in that: the described drum 3 that knocks is made up of cylinder annular metal drum frame and the strike drum face 5 that is arranged on this drum frame one end, this drum frame by about two support columns be supported on the supporting seat 1; The described drum 4 that shaken is by forming with the strike drum face 6 that is arranged on this drum frame one end with the described cylinder annular metal drum frame that knocks drum 3 identical sizes, this drum frame is supported on the supporting seat 2 by two support columns up and down, hangs a bead 7 in the outside of described strike drum face 6 by a rhizoid line.
Described knocking between drum 3 and the vibration drum 4 at a distance of three meters.
Described bead 7 is made of metal or wooden materials.
Described supporting seat 1,2 is made of wooden materials.
The utility model resonance demonstration apparatus knocks drum 3 by strike, produce vibration, vibration is passed to described knocking on the vibration drum 4 that drum 3 has identical intrinsic frequency and is caused resonance, so that vibration drum 4 also begins vibration, bead 7 wooden and the metal fittings suspention is understood oneself and jumped up.So the demonstration of image covibration so that also just the primary school of stage of development and the student of kindergarten by this demonstration can be specifically, vivid, understand covibration intuitively.
Compared with prior art, the utlity model has following advantage:
1, intuitive.Audio-visual aids can make specific knowledge, visualization, for student's perception, understanding and memory Knowledge Creation condition.Intuitively can impel student's concrete perception to combine with abstract thinking, reduce the difficulty of students abstract concept, help it to form clear and definite concept, develop its observation ability and thinking ability, improve student's learning interest and enthusiasm.
2, typicalness.The typicalness of audio-visual aids makes it meet the teaching requirement, can effectively form presentation clearly and guiding student get on to be familiar with things from the phenomenon of showing essence.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 the utility model resonance effect apparatus for demonstrating.
Among the figure: 1,2. supporting seat, 3. knock drum, 4. vibration drum, 5,6. hit drum surface, 7. bead.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Resonance effect apparatus for demonstrating as shown in Figure 1, comprise one serve as vibration source knock drum 3 and the passive drum 4 that shaken that is shaken, the described drum 3 that knocks is arranged at same surface level with the drum 4 that shaken, be and be provided with in opposite directions and both at least one apart rice, it is characterized in that: the described drum 3 that knocks is made up of cylinder annular metal drum frame and the strike drum face 5 that is arranged on this drum frame one end, this drum frame by about two support columns be supported on the supporting seat 1; The described drum 4 that shaken is by forming with the strike drum face 6 that is arranged on this drum frame one end with the described cylinder annular metal drum frame that knocks drum 3 identical sizes, this drum frame is supported on the supporting seat 2 by two support columns up and down, hangs a bead 7 in the outside of described strike drum face 6 by a rhizoid line.
Described knocking between drum 3 and the vibration drum 4 at a distance of three meters.
