Description
Technical field
The utility model relates to a kind of physics facility, specifically a kind of sound wave apparatus for demonstrating.
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.
Although the demonstration of sound wave occurs at present, its demonstrating effect is poor, and structure is scattered, and presentation process needs conversion repeatedly to see, adds the difficulty of student's understanding and cognition sound wave on the contrary, is unfavorable for that student understands and learns.
Summary of the invention
For the problems referred to above, the utility model provides a kind of sound wave apparatus for demonstrating, solves existing its structure of sound wave presentation tool scattered, needs repeatedly to transform and just can see demonstrating effect, the problem that the difficulty causing student to understand difficulty increases.
For achieving the above object, the technical solution of the utility model is specific as follows:
A kind of sound wave apparatus for demonstrating, comprises housing 1, base 9; It is characterized in that: described housing 1 is arranged on base 9, the top of described housing 1 arranges bulb box 4, described bulb box 4 evenly arranges bulb 5 successively, one end in described housing 1 arranges electric cabinet 2, the other end sets gradually some vibrating diaphragms 8, and the position of described vibrating diaphragm 8 and bulb 5 and quantity corresponding, described vibrating diaphragm 8 arranges vibration transducer 7; The side that described electric cabinet 2 is corresponding with vibrating diaphragm 8 arranges loudspeaker 6, and the side of described electric cabinet 2 arranges keyboard 3, is equipped with power supply, music player and power amplifier in described electric cabinet 2.
A wherein sound wave apparatus for demonstrating, described vibrating diaphragm 8, its material is specially boron carbon fiber.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use, easy to operate, solve existing its structure of sound wave presentation tool scattered, need repeatedly to transform and just can see demonstrating effect, the problem that the difficulty causing student to understand difficulty increases, the convenient principle demonstrating Acoustic Wave Propagation intuitively, the efficiency that improve teachers' instruction and Students ' Learning physical knowledge is simple to operate, easy to use, practical reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1. housing, 2. electric cabinet, 3. keyboard, 4. bulb box, 5. bulb, 6. loudspeaker, 7. vibration transducer, 8. vibrating diaphragm, 9. base.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further described:
A kind of sound wave apparatus for demonstrating, comprises housing 1, base 9; It is characterized in that: described housing 1 is arranged on base 9, the top of described housing 1 arranges bulb box 4, described bulb box 4 evenly arranges bulb 5 successively, one end in described housing 1 arranges electric cabinet 2, the other end sets gradually some vibrating diaphragms 8, and the position of described vibrating diaphragm 8 and bulb 5 and quantity corresponding, described vibrating diaphragm 8 arranges vibration transducer 7; The side that described electric cabinet 2 is corresponding with vibrating diaphragm 8 arranges loudspeaker 6, and the side of described electric cabinet 2 arranges keyboard 3, is equipped with power supply, music player and power amplifier in described electric cabinet 2.
A wherein sound wave apparatus for demonstrating, described vibrating diaphragm 8, its material is specially boron carbon fiber.
This practicality in use, loudspeaker 6 are made to release sound by the keyboard 3 on operation electric cabinet 2, along with the propagation of sound, vibrating diaphragm 8 is vibrated, and by vibration transducer 7, bulb 5 being lighted successively, its power is larger, sound transmission far away, vibrating diaphragm 8 vibrates stronger, and its bulb 5 is bright more successively; Its dynamic rate is less, sound transmission nearer, and vibrating diaphragm 8 vibrates more weak, and it is more that its bulb 5 extinguishes successively, and the light of its bulb 5 is more weak.
The utility model structure is simple, easy to use, easy to operate, solve existing its structure of sound wave presentation tool scattered, need repeatedly to transform and just can see demonstrating effect, the problem that the difficulty causing student to understand difficulty increases, the convenient principle demonstrating Acoustic Wave Propagation intuitively, the efficiency that improve teachers' instruction and Students ' Learning physical knowledge is simple to operate, easy to use, practical reliable.
Claims (2)
1. a sound wave apparatus for demonstrating, comprises housing (1), base (9); It is characterized in that: described housing (1) is arranged on base (9), the top of described housing (1) arranges bulb box (4), described bulb box (4) evenly arranges bulb (5) successively, one end in described housing (1) arranges electric cabinet (2), the other end sets gradually some vibrating diaphragms (8), and the position of described vibrating diaphragm (8) and bulb (5) and quantity corresponding, described vibrating diaphragm (8) arranges vibration transducer (7); The side that described electric cabinet (2) is corresponding with vibrating diaphragm (8) arranges loudspeaker (6), the side of described electric cabinet (2) arranges keyboard (3), is equipped with power supply, music player and power amplifier in described electric cabinet (2).
