Title (EN) LABORATORY MILL
(FR) BROYEUR DE LABORATOIRE
(DE) LABORMÜHLE
Abstract:
(EN) The invention relates to a laboratory mill comprising at least one counter-vibration device (27) which has at least one control unit (29a) for providing a counter-vibration signal (29b) and at least one controllable vibration generation unit (29) for converting the counter-vibration signal (29b) into counter-vibrations (30), wherein the vibration-generation unit (29) counteracts a device- and/or housing part (31) of the laboratory mill (1) and the counter-vibrations (30) lead to an active reduction in the vibrations of the device- and/or housing part (31) and/or an at least partial suppression of noise-inducing vibrations of the device- and/or housing part (31), by means of destructive interference.
(FR) L'invention concerne un broyeur de laboratoire comprenant au moins un dispositif à contre-vibrations (27) qui présente au moins une unité de commande (29a) destinée à fournir un signal de contre-vibration (29b) et au moins une unité de génération de vibrations (29) commandable servant à convertir le signal de contre-vibration (29b) en contre-vibrations (30). Ladite unité de génération de vibrations (29) agit contre une partie d'appareil et/ou de boîtier (31) du broyeur de laboratoire (1), et les contre-vibrations (30) permettent de réduire activement les vibrations de la partie d'appareil et/ou de boîtier (31) et/ou de supprimer au moins en partie les vibrations génératrices de bruit parasite au niveau de la partie d'appareil et/ou de boîtier (31) par interférence destructive.
(DE) Eine Labormühle mit wenigstens einer Gegenschwingungseinrichtung (27), die wenigstens eine Steuereinheit (29a) zur Bereitstellung eines Gegenschwingungssignals (29b) und wenigstens eine ansteuerbare Schwingungserzeugungseinheit (29) zur Umwandlung des Gegenschwingungssignals (29b) in Gegenschwingungen (30) aufweist, wobei die Schwingungserzeugungseinheit (29) gegen ein Geräte- und/oder Gehäuseteil (31) der Labormühle (1) wirkt und wobei durch die Gegenschwingungen (30) eine aktive Schwingungsreduktion des Geräte- und/oder Gehäuseteils (31) und/oder eine zumindest teilweise Auslöschung von Störschall erzeugenden Schwingungen des Geräte- und/oder Gehäuseteils (31) durch destruktive Interferenz bewirkt wird.
