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.
