An assembly includes a plurality of gongs, which are connected to at least one gong carrier for a striking mechanism of a watch. Some gongs each connected to a respective gong carrier and a group of gongs connected to one and the same gong carrier are produced with materials different from each other.

A resonant member for a striking mechanism of a watch or of a music box includes at least one resonant part, such as one or more gongs, arranged to vibrate and resonate once activated, and an attachment part. The resonant part and/or the attachment part is made from an alloy of tungsten or tantalum or rhodium or hafnium with more than 51% of tungsten or tantalum or rhodium or hafnium in the alloy.

This invention teaches a new class of materials that can be used to manufacture hairsprings and/or other components of mechanical watches, and methods for manufacturing these components. The new class of materials is crystalline compounds, including, but not limited to, gallium arsenide, extrinsically doped gallium arsenide, extrinsically doped silicon, gallium nitride, extrinsically doped gallium nitride, gallium phosphide, extrinsically doped gallium phosphide, and quartz. This invention also teaches laminated/coated crystalline compounds. The lamination/coating may be applied by one of the following methods, including but not limited to: plasma enhanced chemical vapor deposition, atomic layer deposition, sputtering, electron beam evaporation, and thermal evaporation. Using crystalline compounds, in particular extrinsically doping the crystalline compounds, affords the possibility to controllably alter the mechanical, electrical, thermal, magnetic, and/or other properties of the watch components. These properties can be further altered by applying single or multiple laminates/coatings of varying thicknesses and/or geometries.

The gong is made with a wire or a strip having an atypical shape for a watch striking mechanism. The gong includes a rectilinear part connected to a curved part. The rectilinear part and/or the curved part are connected to the same gong-carrier. The gong includes several notches made at defined geometric points on a portion of the length of the gong to adapt the natural vibration frequencies within an audible range between 1 kHz and 5 kHz, so that the sound produced by the vibrating gong is harmonious.

A striking mechanism is for a watch or music box that includes a vibration plate with optimized actuation energy. The striking mechanism includes a plurality of cantilevered strips. These strips are each made of a material of Young's modulus E and of density ρ satisfying the inequality: $\sqrt{\frac{E}{{\rho }^3}}<0.25m\text{/}s.$
All of the strips (2) each satisfy the relation: ${\delta }_{f,b,20\mu W}\left(L\right)={\left(\frac{8U}{b}\right)}^{\frac{1}{2}}{{\left(\frac{3.515}{4\pi f}\right)}^{\frac{3}{2}}[\frac{E}{{(}^{}}}^{}$

A musical timepiece includes a gong fastened to a structure or a resonator of a watch case, the resonator rigidly assembled to the structure around a chamber, by lugs allowing vibration of the resonator within a determined frequency range, the chamber enclosing a sealing element forming with the lugs the only mechanical connection between the structure and the resonator. The structure or the resonator includes a groove receiving a gasket in contact with the structure and the resonator The structure structure or the resonator or the sealing element includes a rigid protruding relief portion compressing a gasket in its groove, with a hardness less than 20 Shore A, for minimum damping of the vibration of the resonator.
