Abstract
The utility model belongs to teaching equipment, in particular to a shocking phenomenon visualizer which comprises a body (1). A signal source (2), a power amplifier (3) and a horn (5) are arranged on the body, wherein the signal source (2), the power amplifier (3) and the horn (5) are successively connected. One side of the horn mouth of the horn (5) is provided with a displaying screen (7) and the other side of the horn mouth of the horn is provided with a light source. Soap films are arranged between the horn (5) and the displaying screen (7). The center of the light source (4), the center of the soap films (6) and the center of the displaying screen (7) are on the same height. The shocking phenomenon visualizer has the advantages of being simple in structure, convenient in operation and obvious in effect and enables students to watch the forms of shock waves intuitively, thereby enriching teaching contents and teaching methods.
Description
Technical field
The utility model belongs to instruments used for education, particularly a kind of seismism visualizer.
Background technology
Vibrations are nature common phenomena.In the physics teaching in middle school, seismism is focal points, and textbook has provided the function expression and the figure of vibrations.But in the prior art, do not have instrument to simulate shock wave, can not give the understanding of student's perception.In order to allow middle school student that the form of vibration wave is had perceptual knowledge better, exploitation seismism visualizer has the comparison realistic meanings.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of seismism visualizer is provided, and this visualizer can observe shock wave intuitively.
To achieve these goals, the technical solution of the utility model is as follows: a kind of seismism visualizer, it comprises body, signalization source, power amplifier, loudspeaker on the body, signal source, power amplifier, loudspeaker connect successively, and a bell-mouthed side of loudspeaker is provided with display screen, and the bell-mouthed opposite side of loudspeaker is provided with light source, between loudspeaker and the display screen soap film is set, the central point of the central point of light source, the central point of soap film, display screen is positioned at sustained height.
During the demonstration beginning, provide vibration signal by signal source, vibration signal passes to loudspeaker through after the amplification of power amplifier, and the vibrations of loudspeaker drive the vibrations of soap film.Because the central point of light source, the central point of soap film, the central point of display screen are positioned at sustained height, open light source, the light of light source can see through soap film and shine on the display screen.When soap film shook, what show on the display screen promptly was the soap film ripple in when vibrations.
The utility model is simple in structure, operates easyly, and effect is obvious, makes the student can see the form of shock wave intuitively, has enriched the content of courses and teaching means.
