Abstract

Piezoelektrisk resonator (10) inn-rettet for montering uten restriksjoner med hensyn til retning. Resonatoren inn-befatter en seksjonsoppdelt kjerne (12) for piezoelektrisk vibrasjon, med tverr-stilte seksjoner (13) avløst av par eller grupper av indre elektroder. (14, 14). Første henholdsvis andre filmstrimler (16, 18) for isolasjon er lagt på to sideflater normalt på hverandre av de i alt fire sideflater på kjernen (12), henholdsvis på de to motliggende sideflater. Første henholdsvis andre ytre elektroder (20a, 22a; 20b, 22b) er lagt på de to sideflater hvor de første henholdsvis andre filmstrimler (16, 18) er anordnet, henholdsvis der disse filmstrimler mangler. De første og andre ytre elektroder (20a, 20b) er koplet til den andre gruppe av indre elektroder (14 ). På den annen side er en annen første ytre elektrode (22a) utformet på en av de to sideflater hvor de andre filmstrimler (18) er anordnet, og en annen ytre andre elektrode (22b) er lagt på de andre av disse to sideflater. Disse første og andre ytre elektroder (22a, 22b) er koplet til den første gruppe av indre elektroder (14).
