Abstract
The invention relates to the technical field of physics teaching aids, in particular to a sound wave vibration demonstrator comprising a trumpet-shaped cylinder, cylinder mouth vibration membrane, cylinder bottom vibration membrane, a bracket, an LED (light emitting diode) and a button battery box. The sound wave vibration demonstrator is characterized in that the cylinder mouth vibration membrane and the cylinder bottom vibration membrane are mounted at two ends of the trumpet-shaped cylinder, the LED is adhered to the center of the cylinder bottom vibration membrane, and the button battery box is adhered to the trumpet-shaped cylinder which is fixed on the bracket. By means of the sound wave vibration demonstrator, amplitude of the sound wave vibration can be amplified, and effect of vibration can be indicated through the LED, so that students can see rules of the sound wave vibration conveniently, learning interest of the students is improved, and being tired of study due to boring words is avoided.
Description
Technical field
The present invention relates to the physical teaching aid technical field, specifically a kind of acoustic vibration demonstration device.
Background technology
In existing physics teaching, method with experimental demonstration is even more important, not only can allow intuitively the 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 the classroom, also do not have a kind of teaching aid intuitively to allow the student see intuitively the rule of acoustic vibration, so how to allow the student knowledge of sound wave be obtained demonstrating the place of the mathematical expectation that is numerous teachers in apparatus for demonstrating.
Summary of the invention
The objective of the invention is for above-mentioned the deficiencies in the prior art, a kind of acoustic vibration demonstration device is provided.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of acoustic vibration demonstration device 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, and 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 the vibrating effect indication by light emitting diode, can allow easily the student see the rule of acoustic vibration, improves learning interest, eliminates the phenomenon that allows the student be weary of because of uninteresting word.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
