Abstract

In this paper a new type of piezoelectric floating mass type transducer (PFMT) which has advantages of the piezoelectric transducers and the electromagnetic ones has been proposed and designed. To evaluate the frequency characteristics of the PFMT, the finite element analysis and the acoustic simulation of transducer have been performed. The designed PFMT was implemented by a precision manufacturing and the vibration characteristics of the PFMT were measured. Through the measured results from various experiments, it is verified that the implemented PFMT can be used in implantable middle ear hearing devices.
