Indeed, if the diffusion of the sound is easy in the case of clocks of salon or clocks, which have volumes or sound boxes designed to diffuse the sound, and widely dimensioned, it always poses problem in the case of small timepieces, where the volume to constitute a box or a resonant cavity is necessarily very limited, and where many components hinder sound diffusion, dampening rather than amplifying it.

A vibration in the plane tangent to the ice is only obtained with an oscillator generating vibrations in this direction.
  • the patent CH 626 497 on behalf of Ebauches, has innovated by allowing the use of ice as a vibrating organ, serving as a vibration transmitting member, thanks to the interposition, between the bezel and the ice, of a thin annular connecting piece, which absorbs little energy, and does not alter the sound.
  • These provisions were taken up by the patent EP 0 694 824 on behalf of Asulab and by the patent CH 698 742 in the name of Richemont, in which the annular piece adopts a broken line profile.
  • These solutions have the advantage of not deforming the sound, and little damping vibrations, but the amplitude of vibration of the ice remains limited because of the peripheral support of the latter.
  • the invention proposes to bring a new solution to the problem of the transmission of sound by using ice as a vibrating and radiating organ, with respect for the quality of its expected, thanks to a good transmission of vibrations from the mechanism of emission of the sound signal of the timepiece to the ice through the bezel, with a sharp increase in the acoustic level regardless of the installation location of the mechanism emission of the sound signal in the timepiece.

  • the vibration produced by this vibratory source is transmitted to elements that can radiate, such as the middle and the bezel, provided however that no isolator or damper element is interposed in the path of the vibration.
  • the vibration can not be transmitted to the ice, because it is usually insulated with a seal whose function is to seal the watch, and / or it is driven into the bezel by the intermediate of a hard plastic seal. As a result, the ice is not vibrated and can not radiate, which explains the limitations of the prior art.

Conversely, if the ice 2 is maintained only by a single junction zone 4, in single embedding, for example welded at a point, the lowering of the first natural frequency is obtained, albeit with a lower impact resistance. good.

  • the invention is also applicable to a direct mounting of the window 2 in the middle part 6, but the mounting of the window 2 in the window 3 according to the invention allows, precisely, independence from the room 100, and the invention can be implemented easily for any timepiece, replacing the original bezel and / or the ice by a set ice-glasses 1 according to the invention, or even by adapting the original parts by machining and / or by the interposition of adequate bearing blocks as described above.
  • the invention focuses on transmitting the vibrations from the sound source to the ice to make it resonate.
  • the vibratory chain transmits the vibration from the vibratory source, ring, timbre, gong, chime, music box, vibrator, or other, to the turntable of the timepiece, the platinum to the middle of the timepiece, from the case to the bezel, and the bezel to the ice.
