Vibrating actuator

A vibration actuator comprising:

• a plate-shaped body made from a magnetic material that has a flat supporting surface;
• a movable element that is in partial contact, either directly or through a contact piece, in a plurality of locations of the supporting surface, and that vibrates in an axial direction along the supporting surface;
• an elastic member elastically repelling the vibration of the movable element;
• and
• a coil secured to the plate-shaped body, and wherein a coil part that is perpendicular to the axial direction is disposed in a space between the movable element and the plate-shaped body, wherein:
• the movable element comprises a magnet;
• and
• the magnet is disposed facing a coil part of the coil, and comprisies one magnet piece that has a direction of magnetization that is perpendicular to the supporting surface, and another magnet piece that forms a magnetic field that is deflected to the supporting surface side.

A vibration actuator, comprising:

• a supporting plate comprising an outer shape edge that is curved, and a guiding portion, in an inner surface, that has a vibration track along the outer shape edge;
• a movable element that undergoes reciprocating vibration along the vibration track, guided by the guiding portion, through being biased toward the inner surface side;
• a driving portion causing the movable element to undergo reciprocating vibration along the inner surface;
• and
• an elastic member supporting elastically the reciprocating vibration of the movable element.
