A PIEZOELECTRIC BONE CONDUCTION DEVICE HAVING ENHANCED TRANSDUCER STROKE

摘要

A bone conduction device for enhancing the hearing of a recipient, comprising a sound input element configured to receive an acoustic sound signal and an electronics module configured generate an electrical signal representing the acoustic sound signal. The device further comprises an piezoelectric transducer comprising at least one piezoelectric element configured to deform along at least one axis in response to an application of the electrical signal thereto, the transducer configured to generate an transducer stroke based on the deformation, the stroke having a magnitude that exceeds the magnitude of the deformation, wherein the transducer stroke is utilized to generate a mechanical force for delivery to the recipient's skull.
