The acoustic and vacuous demonstration teaching aid structurally comprises a metal ring, a transparent glass bottle, an injector, a lifting rope and a connecting device, wherein the connecting device comprises a hose, a connector and a locking valve; the hose is arranged at the mouth of the transparent glass bottle; the injector is connected with the hose together through the connector; a locking valve is arranged on the connector; the lifting rope is arranged in a bottle cover of the transparent glass bottle; and the metal ring is arranged in the transparent glass bottle through the lifting rope. Compared with the prior art, the utility model improves the teaching efficiency, is helpful to students to memorize related knowledge, can ensure that the students can conveniently comprehend the relationship between the sound and vacuum through the demonstration device in the teaching process of a teacher, thereby increasing the learning interest, and can progressively cultivate the students' interest to physical knowledge and further unceasingly improve in study in the interest by utilizing the way of teaching material teaching, thereby eliminating the phenomenon that the students are tired of study due to boring characters.
Description
1, technical field
The utility model relates to the physical teaching aid technical field, the demonstration teaching aid of specifically a kind of sound and vacuum.
2, background technology
In the existing physics teaching, method with experimental demonstration is even more important, not only can allow the student see the phenomenon of physics more intuitively, and can method by experiment allow the more deep grasp series knowledge of student, in the series teaching of sound and vacuum knowledge, present form of teaching, just the mode of telling about literal by teacher on the classroom is explained, also there is not a kind of teaching aid of practicality to allow the student judge the relation of vacuum and sound intuitively, in the course of time, the student is produced be weary of sense, so how to allow the student that the knowledge of sound and vacuum is obtained demonstration in apparatus for demonstrating, and the raising efficient that teacher gives lessons and the student listens to the teacher is numerous teachers' teaching purpose place.
3, summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, and the demonstration teaching aid of a kind of sound and vacuum is provided.
The demonstration teaching aid of a kind of sound of the present utility model and vacuum is realized in the following manner, structure comprises becket, Clear glass bottles and jars, syringe, lifting rope and coupling arrangement, wherein coupling arrangement comprises flexible pipe, joint and lock valve, the opening part of Clear glass bottles and jars is provided with flexible pipe, syringe is connected with flexible pipe by joint and is set together, joint is provided with lock valve, and the bottle cap inside of Clear glass bottles and jars is provided with lifting rope, and becket is arranged on Clear glass bottles and jars inside by lifting rope.
The utility model is compared with prior art, has following outstanding beneficial effect:
(1) improve the efficient of giving lessons, easy to operate, to be convenient to the student and to remember relevant knowledge, teacher can allow the student understand the relation of sound and vacuum by apparatus for demonstrating in the process of giving lessons easily, allows the student grasp serial physical knowledge in the shortest time.
(2) improve students'interest in learning, utilize the mode of teaching aid teaching, can progressively cultivate the interest of students, in interest, constantly improve in study then for physical knowledge, eliminated the phenomenon that allows the student be weary of because of uninteresting literal, made that teaching is more lively more comprehensively.

Description of reference numerals: 1, flexible pipe, 2, lock valve, 3, joint, 4, syringe, 5, lifting rope, 6, becket, 7, Clear glass bottles and jars.
5, embodiment
With reference to explaining below the demonstration teaching aid work of Figure of description to a kind of sound of the present utility model and vacuum.
As shown in Figure 1, the demonstration teaching aid structure of a kind of sound of the present utility model and vacuum comprises becket 6, Clear glass bottles and jars 7, syringe 4, lifting rope 5 and coupling arrangement, wherein coupling arrangement comprises flexible pipe 1, joint 3 and lock valve 2, the opening part of Clear glass bottles and jars 7 is provided with flexible pipe 1, syringe 4 is connected with flexible pipe 1 by joint 3 and is set together, joint 3 is provided with lock valve 2, the bottle cap inside of Clear glass bottles and jars 7 is provided with lifting rope 5, and becket 6 is arranged on Clear glass bottles and jars 7 inside by lifting rope 5.
The using method of the demonstration teaching aid of a kind of sound of the present utility model and vacuum is as follows:
By flexible pipe 1 and joint 3 Clear glass bottles and jars 7 and syringe 4 are linked together, and unclamp lock valve 2, utilize syringe 4 that the air in the Clear glass bottles and jars 7 is found time, when flexible pipe 1 is flattened by atmospheric pressure, no air in the Clear glass bottles and jars 7 is described, by lock valve 2 flexible pipe 1 is blocked, shake Clear glass bottles and jars 7, can find that becket 6 collides, but can't hear sound, when lock valve 2 is unclamped, will fill with gas in the Clear glass bottles and jars 7, shake Clear glass bottles and jars 7 again, can hear the sound of becket 6 collisions, by these phenomenons, the air of can explaining is soniferous medium, can not propagate sound in the vacuum.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
