Abstract
The striking mechanism () for a watch or a music box includes a gong () fixed to a gong-carrier () and an activation member () for activating the gong in a striking mode. The striking mechanism includes a first magnetic element () arranged on the gong () and second magnetic elements () arranged on the periphery of the activation member (), which is a magnetic wheel. In a striking mode, the magnetic wheel is set in rotation at a determined velocity so that the second magnetic elements (), in the form of moving micro-magnets, move in succession and repeatedly into proximity with and opposite the first magnetic element (), which is a fixed micro-magnet of opposite magnetic polarity. The rotation of the magnetic wheel sets the gong vibrating via a periodic variation in the magnetic repulsion or attraction force between the moving micro-magnets and the fixed micro-magnet of the gong.
