Sound wave visualization interaction device

Abstract

The invention relates to the technical field of teaching aids, in particular to a sound wave visualization interaction device which comprises a first cylinder, a second cylinder, a vibration part, a light reflection part and a laser emitter, the first cylinder is provided with a central cavity, a first port and a second port, the first port and the second port are communicated with the central cavity, and the first port is used for receiving a sound wave source; the vibrating piece is mounted at the second port and is suitable for vibrating under the driving of the sound wave source; the reflecting part is mounted on the vibrating part; the two ends of the second barrel are open, and the first end is installed on the second port. The laser emitter is arranged in the second cylinder, and a laser beam emitted by the laser emitter is reflected by the light reflecting piece and then is emitted out from the second end of the second cylinder. According to the structure, sound wave visualization is achieved at a low price on the basis that high-tech elements such as programming and intelligent hardware are not used, scientific knowledge is more three-dimensional and vivid, meanwhile, the interaction mode is novel, teaching through lively activities can be achieved, the learning enthusiasm of students is aroused, and the exploration ability of the students is cultivated.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a sound wave visualization interaction device. Background technique [0002] Based on a large number of interviews and surveys, it is found that most of the young people's cognition and learning of science and physics knowledge are only in the written lesson plan teaching and test-taking learning, but they lack the cognition of the practical application of science and physics knowledge, and even less The enthusiasm of active learning and exploration; at its root, the main reason is that a lot of scientific knowledge is too abstract, and most of the accessible books are formulas and topics, which makes students unable to visualize knowledge, and then subconsciously It has buried the bane of science and physics knowledge being boring, let alone mobilizing the enthusiasm of students to actively explore and seek knowledge.

[0002] Based on a large number of interviews and surveys, it is found that most of the young people's cognition and learning of science and physics knowledge are only in the written lesson plan teaching and test-taking learning, but they lack the cognition of the practical application of science and physics knowledge, and even less The enthusiasm of active learning and exploration; at its root, the main reason is that a lot of scientific knowledge is too abstract, and most of the accessible books are formulas and topics, which makes students unable to visualize knowledge, and then subconsciously It has buried the bane of science and physics knowledge being boring, let alone mobilizing the enthusiasm of students to actively explore and seek knowledge.

[0003] Sound wave visualization is a method of learning and researching sound wave knowledge, but it is mainly realized by high-tech devices such as intelligent hardware and computers, and mainly exists in the research or application of professional fields, and the knowledge system of these devices is complex and the cost of equipment is high. Not intended for learning and use in schools
