Abstract

Piezoelektrisk resonator (10) med en innvendig svingeeksiterbar kjerne (12) med flere piezoelektriske seksjoner anordnet etter hverandre slik at kjernen får lag- inndeling, og med indre tverrelektroder (14) mellom hver seksjon. En første svingedel (24a) utgjør størstedelen av kjernen (12), med seksjonene polarisert i motsatt retning på hver side av de inn- satte indre elektroder (14). På begge sider av den første svingedel (24a) er det satt inn en del av en andre svingedel (24b). En piezoelektrisk seksjon i hver av de to deler av den andre svingedel (24b) er polarisert i samme retning som den tilstøtende piezoelektriske seksjon i den første svingedel (24a), med en indre tverrelektrode (14) innsatt mellom dem. Et elektrisk felt påtrykkes i motsatte retninger på de tilstøtende piezoelek- triske seksjoner på hver side av en indre tverrelektrode (14) i kjernen (12).
