Abstract

The invention discloses a science popularization display device for displaying a human ear structure and a working principle. The science popularization display device comprises an external ear auricle model, a structure for simulating vibration of a tympanic membrane and a fenestra vestibule membrane through silicon thin membranes, a motor-cam-driven auditory ossicle simulation structure, and a structure for demonstrating the working principle of an internal ear through cooperation of a three-dimensional cochlea model and an LED lamp strip. The basic structure of a human ear is intuitively displayed, the exercise mode of a middle ear and the working principle of the internal ear during working of the human ear are simulated, the collaboration relationship of all the parts of the human ear is demonstrated, understanding is easy, and by cooperating with interaction forms such as audio input and output, the good displaying and science popularization effects are achieved.

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...
