TRANSDUCTEUR A ONDES ACOUSTIQUES DE SURFACE ATTAQUE EN DIFFERENTIEL

摘要

A differential-driven transducer consisting of at least one first transducer (5) and a second transducer (6) connected in parallel so that the differential inputs are symmetrical and thus form first and second acoustic channels respectively. The two transducers (5, 6) have a predetermined mutual longitudinal offset. The transducer may be used in mobile radio filters.
