THIN MULTI-FUNCTION VIBRATION ACTUATOR

摘要

[Object] To provide a multi-function vibration actuator capable of being easily implemented in a thin shape with a simple structure and suppressing a decrease in a vibration amplitude. [Solving Means] A magnetic circuit unit includes a pole piece, a magnet, and a yoke and a suspension is made of a magnetic material, so that a magnetic gap is formed between an end portion of an inner circumferential side surface of the suspension and an end portion of the pole piece. Accordingly, it is possible to prevent the magnet in the magnetic circuit unit from being formed in a thin size. In addition, it is possible to implement a multi-function vibration actuator having a thin structure and capable of obtaining a sufficiently sensible vibration.
