Abstract

The device has a lower part (1) made of silicon to absorb vibrations. A ball bearing (2) is placed on an outer cylinder (3) so that the dimensions of the lower part are based on the dimensions of the bearing and on the diameter of the outer and inner cylinders (3, 4) to discharge the vibrations using the bearing. A lead ball (5) is supported on the inner cylinder.

Description

Ce dispositif est destiné à remplacer les pieds d'origine d'un appareil deThis device is intended to replace the original feet of a

Haute-Fidélité (électroniques et enceintes) afin d'améliorer les résultats d'écoute. Trois de ces systèmes sont nécessaires et suffisants pour découpler l'appareil de son support en les disposants en triangle sous celui-ci et en recherchant la  High Fidelity (electronic and pregnant) to improve listening results. Three of these systems are necessary and sufficient to decouple the device from its support by placing them in a triangle under it and looking for the

stabilité optimale en fonction de la répartition des masses de l'appareil à découpler.  optimum stability according to the distribution of the masses of the device to be decoupled.

Un appareil de Haute-Fidélité est perturbé d'une part par les vibrations externes provenant de son support et d'autre part par les vibrations internes causées par l'alimentation dans le cas d'une électronique ou des ondes acoustiques io dans le cas d'une enceinte. Le système de découplage situé entre l'appareil et son support doit donc écouler les vibrations provenant de l'appareil et absorber celles provenant du support.De nombreux systèmes existent déjà : les pointes par exemple, ne satisfont pas la première exigence et les résultats sont donc médiocres, d'autres consistant à déposer l'appareil sur des billes de plombs donnent de meilleurs résultats: le dispositif ici présenté s'inspire de ce principe mais l'utilisation d'un roulement à billes utilisé de manière optimale permet d'obtenir un découplage plus efficace et les qualités musicales de l'appareil ainsi découplé sont ainsi transcendées.  A high fidelity apparatus is disturbed on the one hand by the external vibrations coming from its support and on the other hand by the internal vibrations caused by the power supply in the case of electronics or acoustic waves. 'a speaker. The decoupling system located between the device and its support must therefore dissipate the vibrations coming from the device and absorb those coming from the support. Many systems already exist: the tips for example, do not satisfy the first requirement and the results are therefore poor, others consisting in depositing the apparatus on lead pellets give better results: the device presented here is inspired by this principle but the use of a ball bearing used in an optimal manner makes it possible to obtain a more efficient decoupling and the musical qualities of the thus decoupled apparatus are thus transcended.

La figure 1 illustrera la description du dispositif par une vue en coupe.  Figure 1 will illustrate the description of the device by a sectional view.

L'élément inférieur (1) du dispositif est une pièce métallique qui sera usinée dans un matériau connu pour ses capacités à absorber les vibrations: le zinc est idéal mais le laiton en contient et il est plus économique.Ses dimensions dépendent entièrement de celles du roulement à billes (2 +3+4) utilisé et notamment du diamètre des cylindres (3) et (4), car le roulement à billes doit reposer seulement sur son cylindre extérieur (3) afin que les vibrations s'écoulent par le roulement (2) . Dans le cas contraire, la contrainte mécanique exercée par l'appareil qui repose sur la bille (5) entraîne que seul le cylindre intérieur (4) aurait contact avec (1) et le roulement perdrait une partie de son efficacité . La bille (5) en plomb s'appuie sur le cylindre intérieur (4) . Des variantes existent et donnent de meilleurs résultats encore: - On peut disposer sur la bille (5) un autre roulement à billes (2+3+4). - La bille peut être une interface entre deux dispositifs (1+2+3+4).  The lower element (1) of the device is a metal part that will be machined in a material known for its ability to absorb vibrations: the zinc is ideal but the brass contains and it is more economical.Ses dimensions are entirely dependent on those of the ball bearing (2 + 3 + 4) used and in particular the diameter of the rolls (3) and (4), because the ball bearing must rest only on its outer cylinder (3) so that the vibrations flow through the bearing (2). Otherwise, the mechanical stress exerted by the device which rests on the ball (5) causes only the inner cylinder (4) would contact with (1) and the bearing would lose some of its effectiveness. The ball (5) lead relies on the inner cylinder (4). Variants exist and give even better results: - One can have on the ball (5) another ball bearing (2 + 3 + 4). - The ball can be an interface between two devices (1 + 2 + 3 + 4).

- On peut utiliser un matériau absorbant sous (1) comme le silicone pour améliorer l'efficacité du dispositif.  Absorbent material (1) such as silicone can be used to improve the efficiency of the device.
