Abstract
The invention relates to the technical field of physics teaching aids, and especially relates to a light display acoustic wave vibration demonstration instrument which is composed of a trumpet-shaped cylinder, a cylinder mouth diaphragm, a cylinder bottom diaphragm, a bracket, a light emitting diode and a button battery box. The light display acoustic wave vibration demonstration instrument is characterized in that the cylinder mouth diaphragm and the cylinder bottom diaphragm are arranged on both ends of the trumpet-shaped cylinder; the light emitting diode is adhered at the center of the cylinder bottom diaphragm; the button battery box is adhered on the trumpet-shaped cylinder; and the trumpet-shaped cylinder is fixedly arranged on the bracket. According to the invention, the amplitude of acoustic wave vibration can be amplified; vibration effect indicating can be carried out through the light emitting diode; students easily see the law of acoustic vibration, thus the interest of learning is improved; and the phenomenon that the students are tired, which is caused by boring texts, can be eliminated.
Description
Technical field
The present invention relates to physical teaching aid technical field, specifically a kind of light display acoustic vibration demonstrator.
Background technology
In existing physics teaching, even more important by the method for experimental demonstration, not only can allow intuitively student see the phenomenon of physics, and the more deep grasp series of knowledge of method that can be by experiment, in the teaching of acoustic vibration, teacher just explains by telling about with the mode of word on classroom, also do not have a kind of teaching aid intuitively to allow student see intuitively the rule of acoustic vibration, so how to allow student that the knowledge of sound wave is obtained to the place that demonstration is numerous teachers' mathematical expectation in apparatus for demonstrating.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of light display acoustic vibration demonstrator is provided.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of light display acoustic vibration demonstrator, comprises horn cylindrical, nozzle vibrating membrane, cylinder end vibrating membrane, support, light emitting diode and button cell box.It is characterized in that: nozzle vibrating membrane and cylinder end vibrating membrane are arranged on the two ends of horn cylindrical, central authorities of vibrating membrane at the bottom of light emitting diode cements in tin, button cell box cements on horn cylindrical, and horn cylindrical is packed on support.
Advantage of the present invention and beneficial effect are:
The present invention can amplify the amplitude of acoustic vibration, and carries out vibrating effect instruction by light emitting diode, can allow easily student see the rule of acoustic vibration, improves learning interest, eliminates the phenomenon that allows student be weary of because of uninteresting word.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
