LENS COMPONENT, LENS-DRIVING MECHANISM, CAMERA MODULE, MOVEMENT CONTROL METHOD AND DRIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drive device, capable of easily setting the frequency of the drive waveform applied to a piezoelectric element, without having to take into account the resonance in a stationary member.

SOLUTION: A lens component 30 includes a driving part with a transmission shaft 44 fixed to a piezoelectric element 42. The driving part is fixed directly or indirectly to a lens in a stationary manner. By employing such a lens component assembled by directly or indirectly fixing the driving part in a stationary manner, in advance, the frequency of the drive waveform applied to the piezoelectric element can be set easily, without taking into account the resonance in the stationary member.
