Title (EN) STETHOSCOPE TRANSDUCER
(FR) TRANSDUCTEUR DE DETECTION DE BRUITS CORPORELS
Abstract:
(EN) An acoustic-to-electrical transducer for sensing body sounds is disclosed. The transducer comprises a capacitive sensor, whereby a stethoscope diaphragm (2) forms one plate (3) of a capacitor, with the second plate of the capacitor being co-planar to the diaphragm (2). The capacitance of the two plates varies with the distance between them, said distance being modified by motion of the diaphragm in response to sound pressure. The sensor circuitry (10), manufacturing methods and improvements are disclosed.
(FR) L'invention concerne un transducteur acoustique-électrique de détection de sons émanant du corps. Le transducteur comprend un détecteur capacitif, dans lequel un diaphragme de stéthoscope (2) forme une plaque (3) d'un condensateur, la seconde plaque dudit condensateur étant coplanaire au diaphragme (2). La capacitance des deux plaques varie avec la distance les séparant, ladite distance étant modifiée par déplacement du diaphragme en réponse à une pression sonore. Cette invention a également trait au détecteur, aux circuits (10), aux procédés et améliorations de fabrication.
