Abstract
The invention discloses a kind of Physical Experiment teaching aid structure for demonstrating sound transmission energy, it includes platform（1）, it is characterised in that：Platform（1）On be fixed with base for candle（2）With sound source base（3）, base for candle（2）Top perspex cover（7）, perspex cover（7）Inside it is fixed with candle（6）, sound source base（3）Top is fixed with sound-producing device（4）, sound-producing device（4）It is directed at perspex cover（7）；Test whether sound transmission energy is changed using a sound source against a candle, observation candle flame on prior art physics lesson, but without fixation and the experimental tool of strong operability, it is impossible to allow student to understand well；And the factor such as wind-engaging and acoustic propagation process losses influences when testing, and causes experiment effect undesirable, it is impossible to preferably to allow student to understand the technical problems such as phenomenon and the essence of sound transmission energy.
Description
Technical field
The invention belongs to teaching aid technical field, more particularly to a kind of Physical Experiment teaching aid knot for demonstrating sound transmission energy
Structure.
Background technology
Physics is a science based on experiment, basic means of the Physical Experiment as physics teaching, has it special
Different instructional function：The ability of study can not only be provided for student, verify physical law, and science can be provided
Method of thinking, deepen the awareness to ABC, excite the aspiration to knowledge of student, the exploring ability of training student.Middle school's thing
Basis of the reason experiment as physics, plays extremely special role.It is both the content of teaching, be again teaching method with
Means.The stronger teaching experimental tool of a kind of good operability, practicality is researched and developed in design can not only promote student more intuitively, correctly
Understand physical concept, rule and method, and can more excite student to have deep love for natural science have the glamour and valency of uniqueness
Value.
Sound transmission energy is a part and parcel on physics lesson, but because the understandability of middle school student is limited, sound is passed
The understanding for passing energy is very abstract.It is many old in order to allow student's more directly perceived, more lively understanding sound transmission energy in understanding process
Teacher, scholar devise many experimental methods, and most commonly seen in teaching is against a candle, observation candle fire with a sound source
Whether flame changes, but without fixation and the experimental tool of strong operability, it is impossible to allow student to understand well；And test when by
The factor such as wind and acoustic propagation process losses influences, and causes experiment effect undesirable, it is impossible to preferably to allow student to understand sound transmission
The phenomenon of energy and essence.
The content of the invention：
The technical problem to be solved in the present invention：A kind of Physical Experiment teaching aid structure for demonstrating sound transmission energy is provided, it is existing to solve
Have and test whether sound transmission energy is changed using a sound source against a candle, observation candle flame on technology physicses class
Become, but without fixation and the experimental tool of strong operability, it is impossible to allow student to understand well；And wind-engaging and acoustic propagation when testing
The factors such as process losses influence, and cause experiment effect undesirable, it is impossible to preferably allow student understand the phenomenon of sound transmission energy with
The technical problems such as essence.
Technical solution of the present invention：
A kind of Physical Experiment teaching aid structure for demonstrating sound transmission energy, it includes platform, base for candle harmony is fixed with platform
Source base, the top perspex cover of base for candle, candle is fixed with perspex cover, sound source base top is fixed with sounding
Device, sound-producing device alignment perspex cover.
The top cover of perspex cover is hinged with perspex cover.
Sound-producing device is loudspeaker, and horn switch is provided with loudspeaker bottom.
Bullet, bullet top end opening are enclosed with loudspeaker；And the pronunciation end of loudspeaker and the top alignment of bullet are anti-
Wind cloche.
The position being aligned on perspex cover with sound-producing device offers a mouthful breach.
Base for candle and sound source base are threadedly secured on platform.
Beneficial effects of the present invention：
The present invention one chain-wales of design, platform is fixed on by candle, sound source, when demonstration, can not by scene other because
Element influences, stable light, and simple to operation；Solve experiment sound transmission energy on prior art physics lesson and use a sound source
Against a candle, whether observation candle flame changes, but without fixation and the experimental tool of strong operability, it is impossible to very well
Allow student to understand；And the factor such as wind-engaging and acoustic propagation process losses influences when testing, and causes experiment effect undesirable, it is impossible to
Preferably student is allowed to understand the technical problems such as phenomenon and the essence of sound transmission energy.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
Embodiment：
A kind of Physical Experiment teaching aid structure for demonstrating sound transmission energy, it includes platform 1, the He of base for candle 2 is fixed with platform 1
Sound source base 3, the top perspex cover 7 of base for candle 2, candle 6 is fixed with perspex cover 7, the top of sound source base 3 is consolidated
Surely there is sound-producing device 4, sound-producing device 4 is directed at perspex cover 7.
The top cover 8 of perspex cover 7 is be hinged with perspex cover 7；Convenient candle picks and places, and is easy to light and extinguish wax
Candle.
Sound-producing device 4 is loudspeaker 4, and horn switch 5 is provided with the bottom of loudspeaker 4；It is easy to test operation.
Bullet, bullet top end opening are enclosed with loudspeaker 4；And the pronunciation end of loudspeaker 4 and the top alignment of bullet
Perspex cover 7.The position being aligned on perspex cover 7 with sound-producing device 4 offers a mouthful breach；It is easy to sound to concentrate biography
It is delivered on flame.
Base for candle 2 and sound source base 3 are threadedly secured on platform 1；It is threadably secured, can conveniently adjusts wax
The height of candle base 2 and sound source base 3, so that sound source can be directed at candle flame, improve test effect and intuitive.
