Abstract (en)
[origin: WO2015086317A2] The invention relates to a striking mechanism (50) for a watch (100) or a music box (200) comprising a keyboard (1) with optimised activation energy, comprising a plurality of overhanging blades (2). Said blades (2) are each made of a material with Young's modulus E and density ρ complying with the inequality: formula (I). All of said blades (2) each comply with the ratio: formula (II), wherein b is the width, L the length, δ the lift, f the frequency, and U the activation energy, of the blade (2), U being no lower than 20 microwatts, and the blades (2) are arranged to vibrate between 800 Hz and 4000 Hz. The invention further relates to a timepiece (500), watch (100) or music box (200) comprising such a striking mechanism (50).
