Hefei Science Museum Innovation Exhibits Deepening Design and Production Service Project Exhibition 2- "Amplifier in Ear"
Exhibition dimensions: approximately 1.2 x 0.6 x 1.3 meters (width x depth x height)
Knowledge points:
The smallest bone in the human body is the ossicles in the middle ear, consisting of the malleus, incus, and stapes. These three smallest bones are ingeniously arranged into a ossicular chain lever system, forming a built-in "amplifier" in the human ear, which actually increases the pressure of sound waves transmitted into the ear by 22 times. This is the pressurization effect of the middle ear.
Participation method:
Mechanical interaction
It mainly consists of an enlarged model of the ossicular chain lever structure, an airflow pipeline integrated with a scale, a background plate shaped as the internal structure of the ear, physical specimens of the human malleus, incus, and stapes, a magnifying glass, a display stand, and other components.
The audience can simulate applying pressure to the eardrum by pressing the airbag with their left hand, and directly observe the movement of the ossicular chain lever around the fixed pivot point; At the same time, placing your right hand at the foot plate of the stapes allows you to directly experience the pressure of the high-speed airflow blowing out. In addition, there are physical specimens of human malleus, incus, and stapes on the exhibition stand, equipped with magnifying glasses, allowing visitors to directly observe and understand the "smallness" of ossicles.
Design and process requirements:
The platform is made of sheet metal and the surface is treated with automotive paint.
3D printing materials can be considered for the structural models of the malleus, incus, and stapes. Rubber elastic materials can be used for the sidewall of the tympanic membrane balloon to facilitate compression deformation; The airflow pipeline is made of transparent thin tubes, making it easy for the audience to observe.
The human malleus, incus, and stapes under a magnifying glass are physical specimens. This module has auxiliary lighting devices to facilitate the audience's observation of the specimen.
Each participating module of the exhibition items is stable and durable, with a reasonable lever structure and airbag design. The display effect is obvious and will not break or be damaged.
