PROTECTIVE HOUSING FOR A CERAMIC ACTUATOR

摘要

A housing (20) that protects a ceramic actuator (21) from excessive and damaging displacement comprises a protective structure (25) arranged to limit the motion of the actuator (21) by contacting at least one section of said actuator between fixed and moving end sections of said actuator (21). A miniature camera includes a suspension system for a lens holder (120) actuated by a ceramic actuator (110). The suspension system comprises four pivotally connected link elements (132-135) in form of a parallelogram connected between a housing (100) and the lens holder (120).
