摘要： A vibration generator making a closed loop of a magnetic circuit of a permanent magnet to obtain a high vibrating force while kept small in size, including a reciprocating vibrator having a ring-shaped permanent magnet in a center hole of a ring-shaped weight, a first and second plate springs supporting this reciprocating vibrator at a recessed case and end plate to be able to elastically displace in a thickness direction spanning a first and a second end faces, a tubular toroidal coil passing through a center hole of the permanent magnet and generating a reciprocating vibrating magnetic field for reciprocatingly driving the permanent magnet in the thickness direction, and a columnar core passing through this toroidal coil, the ring-shaped permanent magnet being magnetized in the thickness direction, and the toroidal coil having a lower toroidal coil and an adjoining reversely wound series connected upper toroidal coil coaxial with the same.
