Abstract

L'invention concerne un procédé et un dispositif permettant de modifier les éléments potentiellement oscillants d'un détecteur de vibrations (1), ces éléments potentiellement oscillants (2, 3) étant fixés sur une membrane (5) selon une configuration en fourche oscillante (4). Le dispositif selon l'invention comprend une pièce de fixation (7) ainsi qu'une pièce de guidage (6) entre lesquelles est fixée une zone terminale d'un élément potentiellement oscillant (2, 3) qui est orientée vers ladite membrane (5). Ledit dispositif comprend en outre un poinçon mobile (8) qui est guidé dans une structure support (9) et qui est disposé par rapport à l'élément potentiellement oscillant (2, 3) fixé, de façon à exercer, par avancement, une force de flexion sur la zone terminale dudit élément potentiellement oscillant (2, 3) qui est opposée à ladite membrane (5).
