Abstract

The invention relates to a visual and digital display type sound propagation demonstrator comprising multiple second boxes. Each second box comprises a first accommodating chamber and a second accommodating chamber. The first accommodating chamber is internally provided with a sound propagation device which extends to the outside of the second box body to be connected with a sound decibel meter. The second accommodating chamber is internally provided with a spring knocking hammer. Sound is generated by knocking of the spring knocking hammer and displayed in a visual and digital display mode through the sound decibel meter so that the students are enabled to clearly and visually understand and learn various properties of sound propagation.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, more specifically to a visualized and digitally displayed sound propagation demonstrator. Background technique [0002] In the process of physics teaching, the transmission of sound is one of the courses. However, "sound" is invisible and intangible, and it is difficult for most students to understand the relevant knowledge of "sound transmission" clearly and intuitively. For example, the direction of sound propagation, the propagation characteristics of sound on different media, etc., students can only understand through the teacher's oral description and the description in the course, which seriously affects the students' learning effect and learning enthusiasm. Contents of the invention [0003] The invention provides a visualized and digitally displayed sound propagation demonstrator to solve the invisible and intangible problem of the existing "sound propagation", and visualize ...
