Striking mechanism for striking watch, has movable and fixed elements arranged on striking portion and gong part, respectively, where hammer is driven toward gong to vibrate gong by pulse due to repulsive force of elements in striking mode

摘要

The mechanism (1) has a movable magnetic element e.g. movable permanent magnet or micro-magnet (20), arranged on a ferromagnetic striking portion of a hammer (2). A fixed magnetic element e.g. fixed permanent magnet or micro-magnet (21), is arranged in a gong part and arranged partially opposite to the movable element. The fixed element generates magnetic field with polarity opposite to that of magnetic field generated by the movable element. The hammer is driven toward a gong (11) for vibrating the gong by magnetic pulse due to repulsive force of the elements, in striking mode.
