Abstract
An actuator which is actuated by an external input and also can remove noise caused by a high frequency by providing a low pass filter capable of preventing a particular high frequency through its mechanical structure. The actuator includes an external gimbal, an internal gimbal, and a connection axis which is disposed in an identical direction to an axis extended from the external gimbal. In this intake, the connection axis is provided between the external gimbal and internal gimbal whereby a not desired high frequency vibration may not be transmitted to a vibrated body provided in the internal gimbal. The actuator constructed as above does not need an electrical control and an additional part, and can be actuated by an external input, and also is highly productive and does not require an additional cost by providing a low pass filter with only comparatively simple change of a mechanical design.
