The invention provides a permanent-magnet-type shock wave generating device. The permanent-magnet-type shock wave generating device comprises a cup body, a water bag, a vibration film, a permanent-magnet vibration body, a base and a coil, the water bag is arranged on the cup body, the vibration film is arranged under the water bag, the permanent-magnet vibration body is fixedly arranged under thevibration film, and the base is arranged in the cup body; the coil is arranged on the base, and is arranged on the periphery of the permanent-magnet vibration body in a winding mode; and when the coilis energized, a magnetic field with the same polarity direction as the permanent-magnet vibration body is generated. Under the action of the magnetic field of the coil, the permanent-magnet vibrationbody is subjected to the push force with the upward direction of the central axis of the coil, thus the vibration film can generate pulse vibration and form shock wave under the drive of the permanent-magnet vibration body.
