Problems solved by technology

[0002] In the existing physics teaching, it is more important to use the method of experimental demonstration. Not only can students see the physical phenomenon intuitively, but also can grasp a series of knowledge more deeply through the experimental method. In the teaching of sound wave vibration, the teacher is in the The classroom is only explained through narration and text. There is no intuitive teaching aid for students to intuitively see the law of sound wave vibration. Therefore, how to let students demonstrate the knowledge of sound waves in the demonstration device is one of the teaching expectations of many teachers. where the

Embodiment Construction

[0009] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0010] refer to figure 1 , a sound wave vibration demonstrator, is made up of trumpet-shaped cylinder 2, cylinder mouth vibrating membrane 1, cylinder bottom vibrating membrane 4, bracket 6, light emitting diode 5 and button battery box 3. The mouth vibrating film 1 and the bottom vibrating film 4 are installed on the two ends of the trumpet-shaped cylinder 2, the light-emitting diode 5 is glued to the center of the bottom vibrating film 4, and the button battery box 3 is glued to the horn-shaped cylinder. On the cylinder 2, the horn-shaped cylinder 2 is fixed on the support 6.

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 [0001] The invention relates to the technical field of physical teaching aids, in particular to a sonic vibration demonstrator. Background technique [0002] In the existing physics teaching, it is more important to use the method of experimental demonstration. Not only can students see the physical phenomenon intuitively, but also can grasp a series of knowledge more deeply through the experimental method. In the teaching of sound wave vibration, the teacher is in the The classroom is only explained through narration and text. There is no intuitive teaching aid for students to intuitively see the law of sound wave vibration. Therefore, how to let students demonstrate the knowledge of sound waves in the demonstration device is one of the teaching expectations of many teachers. where. Contents of the invention [0003] The object of the present invention is to provide a sonic vibration demonstrator aiming at the deficiencies of the above-mentioned prior art...
