Abstract

The invention relates to an experimental device, and in particular relates to a sound propagation experimental device used for physics teaching. The invention aims at solving the technical problem ofproviding a sound propagation experimental device which is used for the physics teaching, can carry out experiment on sound propagation, is visual in teaching, can enable students to have better understanding and is good in teaching quality. For solving the technical problem, the sound propagation experimental device used for the physics teaching comprises a base plate, a vertical plate, a transverse plate, a plug, a bottle, a mounting plate, a vacuum meter and a mobile device, wherein the vertical plate is arranged at the left side of the top of the base plate, the mobile device is arranged at the upper part of the right side surface of the vertical plate, a mobile component of the mobile device is connected with the transverse plate, and the plug is arranged at the right side of the bottom of the transverse plate. The experimental device provided by the invention has the advantages that a buzzer does not need to be put into the bottle by an operator by virtue of a sound producing device, both time and labor are saved, and the effects of carrying out experiment on sound propagation, being visual in teaching, enabling the students to have better understanding and being good in teaching quality are achieved.

Description

technical field [0001] The invention relates to a physics experiment device, in particular to a sound propagation experiment device for physics teaching. Background technique [0002] Teaching is a human-specific talent cultivation activity composed of teachers' teaching and students' learning. Through such activities, teachers guide students to learn and master cultural and scientific knowledge and skills purposefully, in a planned and organized manner, and promote the improvement of students' quality, so that they can become the people needed by society. [0003] In physics teaching, everyone will learn the transmission of sound, and when teachers generally teach sound transmission, they teach through dictation, and the teaching is not intuitive, which makes students unable to understand and the teaching quality is poor. Experiments on sound propagation, while the teaching is intuitive, can enable students to better understand, and the sound propagation experimental devic...
