A “voice coil” is a generalized term that refers to any galvanometer-like mechanism that uses a solenoid to move an object back-and-forth within a magnetic field.
Voice coil actuators, or non-commutated DC linear actuators, consist of a permanent magnetic field assembly (permanent magnets and ferrous steel) and a coil assembly. The current flowing through the coil assembly interacts with the permanent magnetic field and generates a force vector perpendicular to the direction of the current. The force vector can be reversed by changing the polarity of current flowing through the coil.
Voice coil actuators are typically used in focusing applications, oscillatory systems, mirror tilting, and miniature position control.
