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 < 0.25 m / s . All of the strips (2) each satisfy the relation: δ f , b , 20 μ W ( L ) = ( 8 U b ) 1 2 ( 3.515 4 π f ) 3 2 [ E ( 3 ρ ) 3 ] 1 4 L - 3 2 , where b is the width, L the length, δ the travel, f the frequency and U the actuation energy of the strip, U being greater than or equal to 20 microwatts, and the strips (2) are arranged to vibrate between 800 Hz and 4000 Hz.
A striking mechanism for a watch or music box comprising at least one vibration plate with optimized actuation power, the striking mechanism comprising:
