  • the invention also relates to a musical watch box 10 comprising at least one stamp 6 and having a middle part 4.
  • This middle 4 comprises a main receiving surface 40 and a lower receiving surface 45, which is arranged to cooperate in abutment with the distal support face (s) 15 of the lugs 11.
  • the watch case 10 carries, or such a bezel 1 carrying at least one stamp 6, or such a set ice-glasses 3, with the bezel 1 in indirect support on the main reception surface 40 via a first sealing O-ring 51.
  • caseband 4 and the bezel 1 are integrally held by the cooperation of fastening means 17 that includes the bezel 1 and complementary attachment means 47 that includes the middle part 4, in a position where, in the free state of the bezel 1 in the absence of pressure other than atmospheric pressure, the bezel 1 is distant from the main receiving surface 40 by a value corresponding to a predetermined clearance J and not zero.
  • the bezel 1 comprises at least one such lug 11, which lug 11 comprises a thin median thin blade 12.
  • the clearance J is calculated as a function of the maximum overpressure provided on the bezel 1 so that, in case of maximum overpressure on the bezel 1 or in case of shock, each such thin median blade 12 remains in the elastic deformation range, under the effect of a direct support between the bezel 1 and the main receiving surface 40 during the complete crushing of the first O-ring seal 51, thus preventing any irreversible plastic deformation of the thin median blade 12.

  • the bezel 1 has a flange 14 on which is fixed the stamp 6, or the vibration-generating element of a bell-watch (for example, the timbres of a repetition-minutes or a keyboard of a musical watch), which guarantees an optimal vibratory transfer between the vibratory source and the radiating element, without the solidarization of the vibratory source affecting the modes of vibration due to the entire ice-glasses 3.
  • the role of return spring is played by the thin legs 11 for fixing the bezel 1, while the ice 2 plays only the role of inertia of the mechanical system: its piston-type movement creates a mono-polar acoustic source, and makes it possible to generate a very effective acoustic wave in terms of sound perception.
  • the figure 2 represents the assembly of the telescope 1 said disengaged on the middle part 4.
  • the clearance J between the bezel and the middle part is an essential characteristic of the invention, and is necessary to ensure the complete mobility of the bezel 1.

  • the seal is ensured up to 3 bar, since the increase in the external pressure increases the adhesion of the walls of the bezel 1 and the middle 4 of the box 10 against the first O-ring. sealing 51.

  • the finite element simulations make it possible to dimension the mechanical system of the ice-telescope as well as the transfer of vibration between this system and the rest of the casing.
  • the figure 3 represents the frequency responses of the vibratory acceleration (outside the plane of the watch) of two claddings composed on the one hand of a separated lunette 1 (in continuous line) and on the other hand a standard bezel clipped on the middle part (in dotted line). Both skins are similar in terms of size and impact resistance.
  • the first clean mode of a cover consisting of a standard bezel has a frequency of 12 kHz. That composed of a telescope 1 detached has eigen modes in the frequency band between 2 and 10 kHz and in particular three frequencies where the sensitivity of the ear is maximum, above 2 kHz and below 6 kHz .
  • the cladding comprising a bezel-ice unit 3 with a separated bezel 1 has a vibratory response greater than that of a standard cladding in the frequency band 2-10 kHz, which makes it possible to guarantee effective acoustic radiation of the buzzer.
  • the presence of several resonances (peaks) allows the simultaneous tuning of several partials of a stamp or several blades of a keyboard.
  • this system vibrates less for frequencies higher than 13 kHz which is beneficial because generally the noise generated by the striking mechanism has broadband components at very high frequencies: the bezel-ice system with uncoupled bezel is able to filter the sound of the mechanism and prevent the radiation.
