Abstract

L'invention concerne un dispositif d'auscultation de sons biologiques comprenant une membrane piézoélectrique et un ensemble mécanique. Ce dernier comporte un support de membrane sur lequel est montée la membrane piézoélectrique, ainsi qu'un mécanisme de propagation d'ondes disposé sur un côté de la membrane piézoélectrique. Lors de l'utilisation du dispositif d'auscultation de sons biologiques, le mécanisme de propagation d'ondes est intercalé entre la membrane piézoélectrique et le corps de la personne examinée afin de propager les ondes acoustiques depuis le corps de la personne examinée jusqu'à la membrane piézoélectrique. Pour plus d'efficacité, le support de membrane comporte un mécanisme de tension de la membrane piézoélectrique.
