SPRING-LESS VOICE COIL MOTOR

摘要

PURPOSE: A spring-less voice coil motor is provided to reduce power consumption by arranging a mover to perform relative motion with respect to a stator without using a flat spring. CONSTITUTION: A stator(120) is fixed on the top of a base(110). The stator includes a first driving unit(122) generating a first magnetic field. A mover(130) is located inside the stator. The mover includes a lens(132), a bobbin(134) and a second driving unit(136). A magnetic body(140) is engaged with one of the first and second driving units.
