Abstract

In this paper, we report the basic vibrating
characteristics of the piezoelectric artificial cochlea
which consists of piezoelectric and trapezoidal
membrane. The width of the membrane is linearly
changed from 2.0 to 4.0 mm and the length is 30 mm.
The geometry is theoretically designed to realize the
frequency selectivity from 0.7 to 3.6 kHz in the lymph
liquid. The measurement on the vibrating
characteristics is conducted to clarify the effect of the
fluid-structure interaction. Consequently, it is found
that the fluid with the higher density decreases the
resonant frequency of the membrane by increasing the
effective mass for the vibration.
