Abstract

The invention discloses a popular science display device for displaying the structure and working principle of the human ear, which includes a pinna model of the outer ear, a silicone film simulating the vibration of the tympanic membrane and the vestibular window membrane, a motor-cam-driven auditory ossicle simulation structure, and a three-dimensional cochlear model Cooperate with the LED light strip to demonstrate the structure of the working principle of the inner ear; the invention shows the basic structure of the human ear more intuitively, simulates the movement mode of the middle ear and the working principle of the inner ear when the human ear works, and demonstrates the coordination of various parts of the human ear Coordinated relationship, easy to understand, with interactive forms such as audio input and output, it has a better display and science popularization effect.

Description

technical field [0001] The invention belongs to the field of human physiology simulation and science popularization exhibit design, in particular to a science popularization display device for displaying the structure and working principle of the human ear. Background technique [0002] The human ear is an important organ for people to perceive external sounds and obtain information. The human ear has an ingenious structure, precise coordination, and complex working principles. The human ear is divided into three parts: the outer ear, the middle ear, and the inner ear; the pinna of the outer ear has the function of collecting sound and transmitting it into the middle ear; the tympanic membrane of the middle ear and the auditory ossicles convert sound waves into vibrations and transmit them to the inner ear; the cochlea of ​​the inner ear is stimulated by vibration, and the cochlea The flow of lymph fluid in the body promotes the biochemical reaction that produces hearing in...
