Vibration actuator and electronic equipment

A vibration actuator comprising:

• a movable body comprising:
• a disk-shaped magnet;
• a pair of annular cores each having an opening at a center thereof;
• and a pair of spring stopper weight parts, and stacked such that the disk-shaped magnet is disposed at a center of the movable body, the pair of annular cores are fixed on front and rear surfaces of the magnet in an axial direction of the magnet, and the pair of the spring stopper weight parts are joined with the annular cores at the opening;
• and
• a fixing body, having a cylindrical shape, configured to support the spring stopper weight parts by a pair of elastic support parts and accommodate therein the movable body such that the movable body is capable of reciprocally vibrating in the axial direction, and comprising a pair of annular coils disposed outside the movable body in a radial direction thereof,
• wherein each of the spring stopper weight parts comprises:
• a spring fixing part provided at one end in the axial direction and connecting in the axial direction to one of the elastic support parts;
• a joining protrusion part provided at another end and inserted into the opening of one of the annular cores;
• and
• a weight body part provided between the spring fixing part and the joining protrusion part, having a larger diameter than both ends, and disposed to face and join with an annular surface of one of the annular cores.
