Abstract
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 palladium or platinum with more than 51% of palladium or platinum in the alloy.
Claims20
A resonant member suitable for a striking mechanism of a watch or of a music box, the resonant member comprising:
- a resonant part configured to vibrate and resonate once activated;
- and
- an attachment part integral with the resonant part in one-piece form,
- wherein the resonant part comprises a palladium or platinum alloy with more than 51 wt. % palladium or platinum in the alloy,
- wherein the resonant part comprises a first gong,
- wherein the resonant part has a Young's modulus in a range of from 80 to 180 GPa
- wherein the first gong is of circular shape and configured to be disposed inside a watch case describing a circular sector with an angle in a range of from 150 to 250°,
- wherein the resonant part has a hardness greater than 150 HV,
- wherein the first gong is connected on a first end to the attachment part and a second end is free to move,
- wherein the first gong has a deflection distance that is less than 20% of its cross-section, and
- wherein the first gong is configured, once activated, to provide a sound in an audible range of from 1 to 10 KHz.
