專利摘要 |
A springless voice coil actuator is provided. The springless voice coil includes a base, a coil, a guiding rod, a slidable base, a main magnetic component and a balance magnetic component. The coil is disposed on the base. The guiding rod is disposed on the base. The slidable base is for sliding along the guiding rod to a predetermined direction. The main magnetic component is connected to the slidable base. The balance magnetic component is coupled with the main magnetic component for generating a magnetic induction. |
