Title (EN) A MICROPHONE COMPONENT AND A METHOD FOR ITS MANUFACTURE
(FR) COMPOSANTE MICROPHONE ET PROCEDE DE FABRICATION
Abstract:
(EN) The invention relates to a microphone component that may be used in many types of enclosure for making contact with a living body for picking up body sounds. Piezoelectric tranflexural diaphragm elements (3, 5, 6) are known, however, they are only useful as microphone elements when the manner of creating electrical contact does not influence their mechanical properties. According to the invention a microphone component has been developed, which is both rugged and amenable to very inexpensive manufacture. This is obtained in a laminated construction comprising a special layer placed between the piezoelectric transflexural diaphragm element and the electrical interface element.
(FR) L'invention concerne une composante microphone pouvant être utilisée dans de nombreux types d'enceintes pour le contact avec un corps vivant aux fins de détection sonore dans les corps. Il existe des éléments de diaphragme piézo-électriques transflexion (3, 5, 6), néanmoins utiles uniquement comme éléments de microphone lorsque les modalités d'établissement du contact électrique n'influent pas sur leurs propriétés mécaniques. On décrit une composante microphone solide et de fabrication très peu onéreuse, ayant une structure laminée qui comprend une couche spéciale entre les éléments de diaphragme et l'élément d'interface électrique.
