  • the invention also relates to a musical timepiece comprising a ringing or melody play mechanism arranged to make at least one timbre or keyboard resonate attached to a said structure or to a resonator component of a box.
  • the invention relates to the field of striking or musical timepieces, such as minute repeater watches, watches with alarm clock, music boxes, and the like.
  • vibro-acoustic improvements relate mainly to elements of the casing making it possible to increase the acoustic level of the striking, but also to the elements of regulation, to limit the noise of the mechanism when the ringing is triggered and thus increase the emergence of the sound produced by the ringing, by increasing the ratio between the acoustic level of the ringing and that of the noise of the mechanism.
  • radiant glass or separate glasses make it possible to optimize the vibratory response of the covering over a wide frequency band and thus to increase the acoustic level generated by its radiation. So that the elements can have a strong radiating power on a broad frequency band, it is necessary that these last are likely to vibrate freely and this independently of the excitation frequency which they undergo.
  • the vibrational amplitude of the covering depends on a good frequency tuning between the excitation frequency and those of the covering but also on the good solidien transfer between the vibration generating element, such as a stamp or similar, and a radiating element such as a lens-glass assembly or a background. It is therefore necessary that the vibrations propagate easily without being attenuated by intermediate elements between the vibration generating element and the element intended to radiate, nor by seals necessary for sealing the part, which can prevent the radiating elements. to vibrate freely.
  • the document CH 698 742 B1 in the name of RICHEMONT describes a device for connecting a bell to the crystal of a timepiece.
  • the stamp is secured to a heel fixed by screws on part of the movement. This screw extends beyond the dial and is supported by its end face on the underside of an annular segment of an annular elastic piece secured to the crystal.
  • This annular elastic piece has at most four annular segments, each having, in section, a rectilinear shape.
  • the outer edge of the elastic annular piece is intended to be clamped between a bezel and a middle part of the timepiece using a seal:
  • the part of the annular elastic piece that is not under the glass is housed entirely under the bezel.
  • the document EP 2 328 044 A1 in the name of ROLEX describes a watch case comprising a middle part of which at least one opening is closed by a bezel and / or a crystal, or by a back. At least one of the closure elements of the opening is connected to the middle part by an elastic metal member in the form of an endless ring or frame and of hollowed-out cross section defined by the profile of a non-rectilinear wall, the ends of which are integral with the periphery of this closure element, respectively of the middle part.
  • This non-rectilinear wall forms at least one annular fold of orientation parallel to the plane of the opening, this fold being generated by a curvature whose arc describes an angle between 90 ° and 180 °, to give the 'closing element freedom of movement relative to the plane of the opening.
  • the invention proposes to avoid the strong vibration attenuations usually caused by the seals of the covering, and to allow certain elements of the covering which are intended to radiate to vibrate freely.
  • the invention relates to a watch case according to claim 1.
  • the invention also relates to a striking or musical timepiece according to claim 12.
  • the invention proposes to produce a timepiece comprising sound emission means enclosed in a box, and means for radiating the sound vibration towards the user, using certain elements of the covering of the piece. watchmaking, by limiting as much as possible the strong vibration attenuations usually caused by the seals of the covering, in order to allow those elements of the covering which are intended to radiate to vibrate freely, here called the radiating element.
  • the radiating element In order for the vibro-acoustic system constituted by the vibration generating element and the radiating element to be effective, it is important that the radiating element can vibrate freely according to its own modes, which are mainly defined by its fixing system. To prevent vibrations from propagating to the rest of the covering, it is important that the contact between the radiating element and the most rigid part of the box, in particular a middle part, is minimal. However, this type of covering goes against a waterproof construction. The invention optimizes vibration transfer, while guaranteeing the watertightness of the timepiece.
  • the invention is described and illustrated in the particular and non-limiting case of a striking watch, it is directly applicable to a musical watch, a music box, or other similar timepiece.
  • the assembly constituted by the middle part and the back is the most rigid element, and is in direct contact with the user.

  • the sealing element 3 is compressed between them, and each projecting relief compresses a seal in a groove, making the box 100 waterproof.
  • Such a sealing element mounting is not usual, because the grooves usually serve to hold part of a joint whose surface opposite the groove support on a smooth antagonistic surface; moreover, one generally avoids risking injuring a joint by pressing on a projection.
