Abstract:
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: E ρ 3

Abstract:
The acoustic radiating membrane is provided to equip a musical watch or a striking watch. The dome-shaped membrane comprises an active central portion, a lateral wall and a peripheral edge portion for holding the membrane in a watch case. The central part is configured in a convex shape or a conical shape and with dimensions devised to amplify a first vibration mode of one or more notes within a frequency range of between 500 Hz and 3.5 kHz.
