Abstract

Det er frembragt en kompakt miniatyrkondensator og kon- densatormikrofon med god sensitivitet. Den omfatter en fast perforert bakplate som utgjør en fast elektrode i en paral- lellkondensator, følsom for innfallende lydtrykkbølge, og som utgjcr en bevegbar plate i parallellplate-kondensatoren, inn- retning for å posisjonere membranen i forhold til bakplaten uten å påtrykke vesentlig spenning på membranen, og FET- kretser som tilveiebringer et utgangssignal som er proporsjo- nalt i kapasitet til kondensatoren når membranen beveger seg i forhold til bakplaten.
