Abstract

L'invention concerne un dispositif piézoélectrique à quartz. Simultanément, ce dispositif monolithique (i) a plusieurs oscillateurs sur le même quartz, leurs fréquences de résonance pouvant être sélectionnées de façon flexible, (ii) il ne présente aucun problème d'écoute acoustique entre les oscillateurs, et (iii) il facilite un simple adressage des différents oscillateurs.
