Title (EN) DIAPHRAGM CUP FOR AN ULTRASONIC TRANSDUCER AND ULTRASONIC TRANSDUCER
(FR) MEMBRANE EN CUVETTE POUR UN TRANSDUCTEUR À ULTRASONS ET TRANSDUCTEUR À ULTRASONS
(DE) MEMBRANTOPF FÜR EINEN ULTRASCHALLWANDLER UND ULTRASCHALLWANDLER
Abstract:
(EN) The invention relates to a diaphragm cup (10) for an ultrasonic transducer, having a blind-hole-shaped cavity (18), which is bounded by a side wall (12) and a bottom region (13), wherein the bottom region (13) is designed for the fastening of a transducer element (20), wherein the cavity (18) has an oval-shaped inner contour (25) having a major axis (27) and a minor axis (28) in a cross-sectional plane arranged perpendicular to a longitudinal axis (11) of the diaphragm cup (10).
(FR) L'invention concerne une membrane en forme de cuvette (10) pour transducteur à ultrasons, comprenant un évidement en forme de trou borgne (18) qui est délimité par une paroi latérale (12) et une zone de fond (13), la zone de fond (13) étant destinée à la fixation d'un élément de transducteur (20), l'évidement (18) présentant, dans un plan de section transversale perpendiculaire à un axe longitudinal (11) de la membrane en cuvette (10), un profil intérieur ovale (25) présentant un axe principal (27) et un petit axe (28).
(DE) Die Erfindung betrifft einen Membrantopf (10) für einen Ultraschallwandler, mit einer sacklochförmigen Ausnehmung (18), die von einer Seitenwand (12) und einem Bodenbereich (13) begrenzt ist, wobei der Bodenbereich (13) zum Befestigen eines Wandlerelements (20) ausgebildet ist, wobei die Ausnehmung (18) in einer senkrecht zu einer Längsachse (11) des Membrantopfs (10) angeordneten Querschnittsebene eine ovalförmige Innenkontur (25) mit einer Hauptachse (27) und einer Nebenachse (28) aufweist.
