    Abstract: PROBLEM TO BE SOLVED: To provide a multifunctional type vibration actuator by which a vibration amount when physical vibration is generated is obtained while maintaining impact resistance. SOLUTION: The multifunctional type vibration actuator is constituted so that weight of a magnetic circuit part is maintained to secure the vibration amount when the physical vibration is generated even when it is constituted in the longitudinal shape and a voice coil is hard to be deformed in an impact such as falling even when it becomes thin structure as a whole by providing a stopper for impact resistance only to an inner wall on the transverse side or the corner part of a housing. In addition, the vibration amount is improved by providing a weight part to suspension. COPYRIGHT: (C)2009,JPO&INPIT
