A vibration generator includes a tubular magnetic case, an end cover holding a first bearing metal, a second bearing metal held in a burring portion of the bottom plate of the case, a non-magnetic movable thrust shaft that is inserted in an axially movable manner spinning the first and second bearing metal, and first to third toroidal coils connected and fixed at the inner circumference of the case. The vibration generator further includes a first annular pole piece fixed to the movable thrust shaft, a first and a second tubular permanent magnet of axial magnetization, a second annular pole piece and third annular pole piece, first and second wight body fixed at both ends of the movable thrust shaft outside the case, a first coil spring between the end cover and the first wight body, and a second coil spring between the bottom plate and the second wight body.
