Definitions

  • An acoustic radiation membrane for a music box such as a musical watch, or a bell watch.
  • the invention also relates to a watch, which comprises an acoustic radiation membrane.
  • the watch comprises a watch case consisting essentially of a middle and a bottom fixed and securely attached to the middle part.
  • An ice is disposed on a side opposite the bottom to seal said box.
  • a watch movement is maintained inside the watch case and provided with a striking mechanism that can be activated in specified periods of time to produce sound or music.
  • the acoustic radiation membrane is connected to the box to radiate the sound produced by the striking mechanism to the outside of the box.
  • a watch movement of a traditional architecture may also include a striking mechanism for generating a sound or a music.
  • the timbre of the bell watch or the keyboard of the musical watch are arranged inside the watch case.
  • the vibrations of the timbre or the keyboard blades are transmitted to the trim parts.
  • These pieces of clothing are for example the middle part, the bezel, the ice and the bottom of the watch case. These large pieces begin to radiate sound in the air under the effect of transmitted vibrations.
  • a sound is produced either by a stamp struck by a hammer, or by one or more blades of the vibrating keyboard, these parts of dressing are able to radiate the sound produced in the air.
  • the acoustic output based on the complex vibro-acoustic transduction of the trim pieces, is low.
  • the material, geometry and boundary conditions of the trim pieces must be taken into account.
  • the configurations of these pieces of clothing are also dependent on the aesthetics of the watch and operating constraints, which may limit the possibilities of adaptation.
  • a membrane of the acoustic type which is dedicated to vibro-acoustic transduction.
  • a piezoelectric element for example on the membrane to make it vibrate as mentioned in the patent CH 581 860 . So that the sound radiation of the membrane is not lost in the watch, which must be sealed, it can be provided a double bottom of the watch case, which is open to the outside. In this case, the bottom of the watch case has one or more openings for transmitting the sound of the vibrating membrane.
  • this membrane In a standard bell watch, which is provided for example with an acoustic membrane, this membrane is sandwiched between a portion of the middle part and the bottom of the watch case.
  • the bottom can be made of a precious material, such as gold. It can occur in contact with the membrane usually made of steel with the gold bottom, an electrochemical potential difference especially in a humid environment. This is likely to promote the corrosion of said membrane at the contact with the gold background, which is a drawback. It must therefore also be found a stainless material with no potential difference with gold and whose internal damping is low.
  • the invention therefore aims to overcome the drawbacks of the state of the art mentioned above by providing an acoustic radiation membrane for a music box or a striking watch, made in such a way as to obtain the most uniform acoustic performance possible on the audible frequency band, essentially in the frequency range between 1 kHz and 4 kHz.
  • the invention relates to an acoustic radiation membrane comprising the characteristics defined in independent claim 1.
  • An advantage of the acoustic radiation membrane according to the present invention lies in the fact that it is made with at least one region of asymmetric shape formed in the material of the membrane or with at least one region of asymmetrical shape having a different thickness the general thickness of the membrane. It can include several asymmetrically shaped regions, which are excavated in the membrane material. Preferably, two excavated regions of dimension different are planned. A first region is machined for example by etching or digging in the membrane to have a first constant thickness, and a second region is machined in the membrane to have a second constant thickness less than the first thickness.
  • the two asymmetrically shaped regions are machined to define, for example, first and second ellipses as an asymmetric shape. These ellipses are offset from each other with respect to the center of the membrane and overlap in part.
  • the membrane may be made of amorphous metal or metal glass, or also of gold, or even brass or another material having a density, a Young's modulus and an elastic limit, which are similar.
  • the arrangement of the asymmetric regions can thus make it possible to increase the number of eigenfrequencies in the useful acoustic frequency band, namely between 1 kHz and 4 kHz, in order also to increase the overall acoustic level.
  • the widening of the soundtrack can be combined with a very low internal damping, which makes it possible to obtain a very good sound output.
  • the invention also relates to a watch provided with an acoustic radiation membrane comprising the characteristics defined in the independent claim 13.
  • the figure 1 represents a top view of the acoustic radiation membrane 1 for a music box, such as a musical watch, or a striking watch.
  • the membrane 1 is made with a spatially inhomogeneous thickness, i.e. it includes regions, which have been machined in the total thickness of the membrane. The machined regions each have a different uniform thickness.
  • Excavated regions of different thickness have circularly shaped shapes in plan view.
  • the asymmetric shapes are preferably ellipses 2, 3 excavated in a bottom portion 4 of a circular membrane 1, which may be shaped like as explained below with reference to figures 2 and 4 . These ellipses 2, 3 are partly superimposed.
  • the membrane 1 may be a circular membrane with a diameter of about 40 mm at the edge and a diameter of about 31 mm at its bottom 4 by way of non-limiting example. These two elliptical regions occupy a large part of the surface of the membrane seen in plan so as to increase the number of eigen modes of vibration in the desired audible frequency band between 1 kHz and 4 kHz.
  • the elliptical regions are normally determined taking into account the following simplified formula of the frequency ⁇ of the vibration modes of an elliptical membrane: ⁇ 2 not , m ⁇ E ⁇ h ⁇ not / b 2 + m / at 2 / ⁇ ⁇ 1 - v 2
  • E the Young's modulus
  • h the thickness of the membrane
  • a and b are the half-axes of the ellipse
  • p is the density of the membrane material
  • v is the Poisson's ratio (at about the order of 0.3)
  • n and m are integers, which number the modes of vibration and represent the number of nodes spatially of the corresponding vibration of the membrane.
  • the number of nodes in the direction of the half-axis a and the half-axis b is m-1, respectively n-1.
  • this corresponds to a vibration, which has two nodes in the direction of the half-axis a, and a node in the direction of the half-axis b.
  • the frequency increases with the square root of the Young's modulus E and the thickness h, but on the other hand decreases by increasing the half-axes a and b, that is to say the surface of the ellipse.
  • an elliptical membrane has a double number of modes of vibration relative to a circular membrane. It is therefore possible to flatten the overall frequency response by eliminating the circular symmetry of the membrane.
  • the asymmetric regions preferably in the form of an ellipse 2, 3 of the acoustic membrane 1 according to the invention, are configured so that the first natural modes of vibration are in the audible frequency band between 1 kHz and 4 kHz. With such ellipses, this allows for better geometric optimization than for other asymmetric shapes.
  • a circular membrane of uniform thickness supports several eigen modes of vibration, which are defined by k N.
  • Each eigenmode is characterized by a defined number of nodes N. Thanks to the realization of regions of different thickness, which are called S j with j ranging from 1 to n, and for each defined number of nodes N, it is counted several vibration modes k NOT l having this number of nodes. These modes differ from each other in their spatial shape and / or orientation in the plane of the membrane. The energy difference between these modes depends on the thickness and shape of the regions S j and can therefore be reduced to discretion. This multiplication of modes in each energy range makes it possible to widen the response band of the membrane. For simplicity of calculation and practical realization, it is considered the specific case where the regions of different thickness are two ellipses.
  • the first modes of vibration are with a uniform amplification in the desired frequency band, for example between 1 kHz and 4 kHz.
  • the overall acoustic level is also increased for a user's perception of the notes radiated by the membrane of the music box or the ringing watch.

  • the maximum thickness of the membrane may be of the order of 0.3 mm, while the minimum thickness may vary between 0.1 mm and 0.2 mm, depending on the sound effects to be obtained. If the density is greater, while the Young's modulus is smaller, a membrane thickness greater than 0.3 mm may be allowed, but under these conditions, the membrane is less acoustically effective.
  • the size of the first ellipse 2, which is excavated in the bottom 4 of the membrane, is 12 mm for the half-major axis and 6 mm for the half-minor axis with a thickness of 0.15 mm.
  • the size of the second ellipse 3, which is excavated in the bottom 4 of the membrane partially superimposed on the first ellipse and crossed, is 11 mm for the half-major axis and 7 mm for the semi-minor axis with a thickness of 0.2 mm.

  • the density of vibration modes of the membrane is maximized in the desired audible frequency band. It can also be envisaged to adapt the thicknesses and the surface of the ellipses as a function of the desired sealing, the indeformability or the deformability of the desired membrane.
  • the ratio between the half-axes of the ellipses excavated in the membrane and the radius of the circular membrane should in principle be in the range 2/3 to 1.
  • the ratio between the two thicknesses of the ellipses must be in the interval 1/2 to 4/5.
  • the minimum thickness must not be greater than 2/3 of the total thickness of the circular membrane.
  • the figure 2 represents a diametrical cut along AA of the figure 1 of the acoustic radiation membrane 1.
  • This membrane can take the form of a bowl with a bottom 4 and a peripheral edge for mounting in particular in a watch case as explained below with reference to the figure 4 .
  • the asymmetric regions in the form of ellipses 2 and 3 are formed in the bottom 4 of the membrane 1. Each region is excavated in the membrane with each a different uniform thickness. It should also be noted that the excavated regions may be indifferently on the movement side or on the outer side of the membrane not shown.
  • asymmetrical regions 2, 3 by etching, milling or digging in the total thickness of the membrane 1, it can be envisaged to produce on a membrane of minimum thickness two regions. in the form of an ellipse in overthickness and which intersect.
  • a first region has a first thickness greater than the minimum thickness of the membrane, and a second region has a second thickness greater than the first thickness of the first region.
  • These elliptical regions thus form protruding portions on the membrane, but whose asymmetrical shape provides advantages equivalent to the advantages of the ellipses excavated in the membrane explained above.
  • These regions can be obtained by selective deposition of the same material as the base material of the membrane.
  • the material may be zirconia-based or platinum-based metal glass, or also gold.
