Abstract:
1. An actuator comprising: a vibrated body; an external gimbal provided around the vibrated body; a first axis having one end connected to the vibrated body; a second axis externally extended from the external gimbal, such that an axial direction of the first axis is transverse to an axial direction of the second axis; and a mechanical filter comprising an internal gimbal formed between the vibrated body and the external gimbal and connected to another end of the first axis, and a connection axis which connects the internal gimbal and the external gimbal, the connection axis being extended in a same direction as the second axis, wherein the vibrated body is excited by the first axis and the second axis due to a vibration of the external gimbal caused by an external input, such that a vibration of the second axis of the external gimbal travels through the connection axis to the vibrated body.
