Vibration actuator with moving coil and moving magnetic assembly having elastic parts

A vibration actuator comprising:

• a housing;
• a first movable part including a magnet part, and disposed in a movable manner back and forth in a vibration direction along an axis direction in the housing through a first elastic support part joined at both end portions of the magnet part in the axis direction;
• and
• a second movable part including a coil part disposed coaxially with the magnet part so as to surround the magnet part, the second movable part being disposed in a movable manner back and forth in the vibration direction in the housing at an outer periphery of the first movable part through a second elastic support part joined at both end portions of the coil part in the axis direction, wherein
• vibration is generated by driving the first movable part and the second movable part through energization to the coil part, and wherein
• the both end portions of the first movable part are inserted through the second elastic support part and located at positions protruded to outside of the both end portions of the second movable part in the vibration direction so as to be joined to the first elastic support part.
