(FR) GRAMOPHONE AVEC PLATEAU TOURNANT, LÉVITANT SUR COUSSIN MAGNÉTIQUE
Resumo
(EN)
The design of the gramophone (100) for playing music recordings on vinyl records (50) which rotate on a levitating turntable (10) with the help of magnetic forces, substitutes all established versions of analogue gramophones, where the drive and rotation of the turntable are predominantly provided by an electric motor and mechanical elements. The technology of the turntable (10), rotating and levitating on magnetic forces, does not require changing the other elements of the analogue gramophone device, however, its advantage is that it reduces the unwanted vibrations of the turntable (10) and its unsteady rotation while playing music. In this way the accuracy and credibility of the sound readings is improved. Additionally, the need to push the turntable stylus (32) more strongly on the vinyl record (50) is reduced, otherwise required due to the possible skipping of the stylus (32). Thus the format of the sound recording in the groove of the vinyl record (50) is maintained for a longer period of time, as well as the sharpness of the turntable stylus (32). To ensure steady rotation, the excess inertia mass of the turntable (10) is no longer required. In addition to the benefits in sound processing, the new technology also upgrades the level of the visual experience when listening to audio artistic creations. The system of the levitating and rotating turntable can also be used for other purposes, such as to display products in showroom windows and similar.

L'invention porte sur la conception du gramophone (100) pour la lecture d'enregistrements musicaux sur des disques vinyle (50) tournant sur un plateau tournant de lévitation (10) à l'aide de forces magnétiques, laquelle conception remplace toutes les versions établies de gramophones analogiques, l'entraînement et la rotation du plateau tournant étant principalement fournis par un moteur électrique et des éléments mécaniques. La technologie du plateau tournant (10), la rotation et la lévitation sur des forces magnétiques ne nécessitent pas de changer les autres éléments du dispositif de gramophone analogique, cependant, son avantage est qu'elle réduit les vibrations indésirables du plateau tournant (10) et sa rotation instable pendant la lecture de musique. De cette manière, la précision et la crédibilité des lectures sonores sont améliorées. De plus, le besoin de pousser la pointe de lecture de plateau tournant (32) plus fortement sur le disque vinyle (50) est réduit, sinon nécessaire en raison du saut possible de la pointe de lecture (32). Ainsi, le format de l'enregistrement sonore dans le sillon du disque vinyle (50) est maintenu pendant une période de temps plus longue, ainsi que la netteté de la pointe de lecture du plateau tournant (32). Pour assurer une rotation stable, la masse d'inertie en excès du plateau tournant (10) n'est plus nécessaire. Outre les avantages du traitement sonore, la nouvelle technologie met également à niveau le niveau de l'expérience visuelle lors de l'écoute de créations artistiques audio. Le système du plateau tournant à lévitation et rotatif peut également être utilisé à d'autres fins, par exemple pour afficher des produits dans des vitrines de salles d'exposition et similaires.
