Definitions

  • the invention relates to a watch ring or optimized radiation music box with a plurality of cantilever blades.
  • the invention also relates to a watch ring mechanism or music box comprising at least one such keyboard.
  • the invention also relates to a timepiece constituted by a watch or a music box comprising at least one such mechanism and / or at least one such keyboard.
  • the invention relates to the field of timepieces comprising a striking mechanism, including watches and music boxes.
  • the striking mechanism of musical watches or music boxes is generally constituted by a keyboard and an activation system of the blades of this keyboard.
  • the activation system may be a rotating cylinder or a rotating disk, or the like.
  • the keyboard material has been chosen mainly on the basis of manufacturability criteria and resistance to wear and fatigue.
  • the reason is that the keyboard blades are subjected to repeated elastic forces and the friction between the surface of the blades and the activation pins can induce either the abrasion or the matting of the surfaces.
  • manufacturers of bell watches or music boxes have always tried to increase as much as possible the activation energy of the blades, which requires very considerable elastic forces, especially for the shortest blades, corresponding to the most acute sounds.
  • the present invention proposes the introduction of an optimized ring keypad, in a material having particular elastic properties, specific to ensure optimal radiation of the sound emitted by the cladding, and with a specific geometry to store the maximum energy in the smallest space.
  • the coating and curing techniques of the materials nowadays make it possible to reduce the risk of wear and fatigue of the watch components, and make it possible to use relatively flexible materials for the ringer keyboard function.
  • the invention thus comes to propose an unusual solution, and quite contrary to the uses of the profession, by defining an optimized ringtone having both a modulus of elasticity lower than traditionally used steel keyboards and a higher density.
  • the main example of this family of keyboards optimized according to the invention is the keyboard in gold or gold alloy.
  • the invention relates to a watch ring or optimized radiation music box comprising a plurality of blades in cantilever, characterized in that said blades are each in a Young modulus material E and density ⁇ satisfying the inequality E ⁇ 3 ⁇ 0.25 ⁇ m s .
  • said blades are each in a Young's modulus material between 70 GPa and 120 GPa.
  • said blades are each of density greater than 14.
  • the invention also relates to a watch ring mechanism or music box comprising at least one such keyboard.
  • the invention also relates to a timepiece constituted by a watch or a music box comprising at least one such mechanism and / or at least one such keyboard.
  • the invention relates to the field of timepieces comprising a striking mechanism, including watches and music boxes.
  • the invention relates to a keyboard 1 watch ring 100 or music box 200, optimized radiation, comprising a plurality of blades 2 cantilevered.
  • Each of these blades 2 is sized to vibrate at a specific frequency.
  • the entire keyboard 1 is designed to broadcast the sound in a particular frequency range of the audible range. More particularly and not exclusively, this range relates to the frequencies of 800 Hz to 4000 Hz, the conceptual reasoning explained below applying to all other limit values of this frequency range.
  • each blade 2 of the keyboard 1 is made of a material for which E ⁇ 3 ⁇ 0.25 m / s . .
  • these blades 2 are each in a Young's modulus M material between 70 GPa and 120 GPa.
  • these blades 2 are each of density greater than 14, and especially between 14 and 22.
  • At least one blade 2 is made of an alloy comprising gold.
  • At least one blade 2 is made of "750" gold comprising at least 75% gold.
  • all the blades 2 that make up the keyboard 1 form a one-piece assembly with a table 3 by which is fixed the keyboard 1.
  • we can build the keyboard 1 with blades 2 each obey the beaches of Young's modulus and density values according to the invention, and each embedded in a table 3 which itself obeys, preferably, these same ranges of value.
  • each blade 2 is a solid parallelepipedic prism.
  • the same reasoning is applicable to blades 2 of different shapes and sections, solid or hollow.
  • the geometry of the blades 2 (defined by the minimum length, the maximum length, the height h and the width b of the blades) is appropriate.
  • equation (4) makes it possible to determine the optimal configuration uniquely.
  • the maximum size in blade length and total vertical space is represented by the shaded area.
  • the graphs C1 and C2 correspond to the frequency of 4000 Hz, respectively according to the total vertical space h + 2 ⁇ or according to the only lift ⁇ , the graphs C3 and C4 are the pendants for the frequency of 800 Hz.
  • the figure 2 is a representation with a lift evaluated to obtain an activation energy of 20 microwatts, and shows the response of the keyboard at certain frequencies (on the left for a 4000 Hz blade and on the right for a 800 Hz blade) , each solid line curve corresponding to the response with the total vertical footprint, and each dashed curve corresponding to the only lift.
  • the maximum overall length of the blade and the total vertical space, characteristic of the operating limits, are represented by the shaded area. Outside this region, the keyboard can not be integrated into a traditional wristwatch.
  • a steel keyboard does not allow to activate a blade with enough energy to obtain optimal acoustic radiation at all frequencies.
  • equation (4) produces the curves represented in FIG. figure 3 which relates to a keyboard 1 according to the invention in 750 gold, with graphs similar to those of the figure 2 . It can be seen that, in this case, it is also possible to activate the blade at 800 Hz with sufficient energy while remaining within the desired size limits.
  • the improvement over a steel keyboard is made possible by the fact that the frequency and the activation energy of the blade 2 according to the invention have a different functional dependence depending on the parameters and, in particular by the fact that at parity of activation energy: ⁇ 2 ⁇ The 3 ⁇ E ⁇ 3 . for a higher density and / or a modulus of elasticity lower than that of steel, it is therefore possible to reduce either the required lift ⁇ or the length L of the blades 2, or both dimensions simultaneously.
  • At least one blade 2 comprises a surface coating.
  • At least one blade 2 has a hardened surface relative to its core.
  • the invention also relates to a watch 50 ringing mechanism 100 or music box 200 comprising at least one such keyboard 1.
  • the invention also relates to a timepiece 500 constituted by a watch 100 or a music box 200 comprising at least one such mechanism 50 and / or at least one such keyboard 1.
