Abstract

The eardrum (also known as tympanic membrane, TM) in human auditory system has a curved conical shape with the apex pointing medially. It generally receives airborne sound waves collected by the outer ear, transforms them into mechanical vibrations in the eardrum, and eventually transmits the vibrations to the middle ear, which is similar with acoustic transducers such as microphones. In this research, new approach inspired by the human auditory system is explored to address the challenging difficulties for developing advanced acoustic transducers. In addition, a frequency response function analysis is performed to validate the inverse anti-resonance vibrating structure inspired by human middle ear including ear-drum.
