Abstract
Ecouteur stéthoscopique comportant deux bras identiques dont chacun est muni d'un téléphone et qui débouchent dans un élément de liaison articulé comportant au moins un ressort en fil. En fait, ledit élément de liaison est formé par deux éléments de couplage identiques dont l'un est l'image réfléchie de l'autre et qui, à travers une transmission par engrenages coopèrent tout en entourant entièrement le ressort en fil. Ce dernier est formé par exemple par deux ressorts hélicoïdaux placés symétriquement de façon que l'un constitue l'image réfléchie de l'autre, chaque ressort hélicoïdal se trouvant dans une pièce de couplage. Application au dictaphone.
