Striking mechanism for a watch or a music box
First Claim
1. A striking mechanism for a watch or a music box, said striking mechanism including at least one gong secured to a gong-carrier, and at least one activation member for activating the gong to vibrate said gong in a striking mode, wherein the striking mechanism includes at least one first magnetic element arranged in one part of the gong, and at least one second magnetic element arranged on the activation member, wherein the second magnetic element is a moving permanent magnet, wherein in a striking mode the activation member is activated so that the moving permanent magnet repeatedly moves into proximity with and opposite the first magnetic element, which is arranged for generating a magnetic field of opposite polarity to the magnetic field generated by the moving permanent magnet opposite the first magnetic element, so as to vibrate the gong by a repetitive variation in the magnetic repulsion force between the two magnetic elements.

Abstract
The striking mechanism (1) for a watch or a music box includes a gong (11) fixed to a gong-carrier (12) and an activation member (2) for activating the gong in a striking mode. The striking mechanism includes a first magnetic element (13) arranged on the gong (11) and second magnetic elements (4) arranged on the periphery of the activation member (2), 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 (4), in the form of moving micro-magnets, move in succession and repeatedly into proximity with and opposite the first magnetic element (13), 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.

The striking mechanism for a watch or a music box, said striking mechanism including at least one gong secured to a gong-carrier, and at least one activation member for activating the gong to vibrate said gong in a striking mode, wherein the striking mechanism includes at least one first magnetic element arranged in one part of the gong, and at least one second magnetic element arranged on the activation member, wherein the second magnetic element is a moving permanent magnet, and wherein in a striking mode the activation member is activated so that the moving permanent magnet repeatedly moves into proximity with and opposite the first magnetic element, which is arranged for generating a magnetic field of the same polarity as the magnetic field generated by the moving permanent magnet opposite the first magnetic element, so as to vibrate the gong by a repetitive variation in the magnetic attraction force between the two magnetic elements.
