VIBRATION ACTUATOR AND PORTABLE INFORMATION TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a vibration actuator that allows vibrating a magnet and a weight part by large force with a simple structure.SOLUTION: A vibration actuator 100 includes a stator having an enclosure 2 and a coil 15 and a mover having magnets 5 and a weight part 3 disposed in the enclosure 2, and the mover linearly vibrates to the stator in a vibration direction by cooperation with the coil 15 and the magnets 5. The magnets 5 include a first magnet 5 and a second magnet 5 that are magnetized along the vibration direction in the reverse direction to each other, and they are fixed via a yoke member 6. The coil 15 is disposed on an outer peripheral side of the whole or a part of the first magnet 5 and the second magnet 5. The coil 15 is held closely to a bottom surface portion and a lid portion of the enclosure 2.
