THIN MULTI-FUNCTION VIBRATION ACTUATOR |
摘要 |
[PROBLEMS] A multi-function vibration actuator that can be thinned with a simple structure and in which a reduction in the amount of vibration is minimized. [MEANS FOR SOLVING PROBLEMS] A magnetic circuit section is constructed from a pole piece, a magnet, and a yoke, and a suspension is constructed from a magnetic body. This forms a magnetic gap between the end of an inner circumferential side surface of the suspension and the end of the pole piece. As a result, the magnet in the magnetic circuit is prevented from becoming thin and, although the actuator is thin, vibration sufficient to be sensed by the body is obtainable.
