Abstract
An acoustic wave illustrating device includes a demonstration table, which is characterized in that a drum is up placed on one side of the demonstration table, wherein the drum surface is equipped with a flat mirror. A display screen is up placed on the other side of the demonstration table, and one side between the drum and the display screen is equipped with a light source and the other side between the drum and the display screen is equipped with a rotatable six-edge reflector. The beams produced by the light source irradiate on the flat mirror of the drum surface and are reflected to the rotatable six-edge reflector, and the beams reflected by the six-edge reflector irradiate on the screen of the display screen. The utility model has the advantages of simple conformation, strong maneuverability and convenience for students to do experiments on their own. The utility model is available of demonstrating the sound propagating in a wave form, the vibration of a sound producer, the highness and lowness of tunes and the strength of volume.
Description
Technical field
The utility model relates to a kind of physics teaching in secondary school apparatus, particularly relates to a kind of sound wave demonstrator, is to having replenishing of physics teaching in secondary school apparatus kind now, belonging to the school supply and stationery category.
Background technology
At present, the used teaching aid of people is a lot, but function singlenesses all just designs at the content that needs separately to show.The teaching aid of demonstration acoustical vibration is blank especially on the physics lesson of middle school period, the teacher can only say when the above-mentioned notion of explanation general, lack the chance that the student starts to test, the enthusiasm that can not mobilizing students initiatively participates in, be helpless to cultivate students ' analysis problem and problem-solving ability, thereby bring certain difficulty to teaching, even have influence on student performance and learning interest.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of novel sound wave demonstrator, this sound wave demonstrator structure is simple, workable, shows the experimentation of acoustical vibration with the form of innervation, be more convenient for the student do it yourself the experiment, both help the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.
The technical scheme that the utility model provides is: this sound wave demonstrator, include a demonstration platen, be characterized in erectting on the side of described demonstration platen a drum is arranged, the bulging face of this drum is provided with a level crossing, erect on the opposite side of described demonstration platen a display screen is arranged, side between described drum and the display screen is provided with a light source, opposite side between drum and the display screen is provided with rotating six rib catoptrons, the irradiate light that light source sends is on the level crossing of drum face, and be reflected onto on the rotating six rib catoptrons, by the irradiate light of six rib mirror surfaces reflections on the panel of display screen.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, workable, the experimentation that shows acoustical vibration with the form of innervation, be more convenient for the student do it yourself the experiment, both help the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.
Description of drawings
Accompanying drawing is the structural representation of the embodiment that provides of the utility model.
Embodiment
As shown in drawings, this sound wave demonstrator, include a demonstration platen, erect on one side of demonstration platen a drum 1 is arranged, the bulging face of this drum 1 is provided with a level crossing 2, erect on the opposite side of demonstration platen a display screen 3 is arranged, side between drum 1 and the display screen 3 is provided with a light source 4, opposite side between drum 1 and the display screen 3 is provided with rotating six rib catoptrons 5, the rotation system of this six ribs catoptron 5 is driven by the motor 6 that is located under it, the irradiate light that light source 4 sends and is reflected onto on the rotating six rib catoptrons 5 on the level crossing 2 of drum face, by the irradiate light of six rib catoptrons, 5 reflections on the panel of display screen 3.
During demonstration, impact the bulging face of drum 1 with glass bar 7, bulging face is shaken, because the light that light source 4 sends is radiated on the level crossing 2 of bulging face all the time, and be reflected onto on the rotating six rib catoptrons 5, on the panel of display screen 3, vibrations take place the drum face certainly will cause level crossing 2 vibrations that are arranged on the bulging face by the irradiate light of six rib catoptrons 5 reflection, thereby the ray trajectory on the panel that reflexes to display screen 3 is changed, promptly be similar to the sound wave shock curve.
Utilize the utility model to propagate with the form of ripple by demonstrating sound, the object that also can demonstrate sounding is all vibrating, the tone height of all right demonstrating sound and the power of loudness.
