Gegenstand der Erfindung ist «im Kleinstmikrofon, bei welche» ein pieao-elektrieehes keramisches Sleiient, vorzugsweise Bariumtitanat, »I* Wandler eingesetst ist.The subject of the invention is “in the miniature microphone, in which” a pieao-electric ceramic sleiient, preferably barium titanate, »I * converter is used.
Bei den bisher gebräuchlich·!! KIe in β ta lkr ο fönen »it Wandlern aus
Seignettesal»elementen besteht der Nachteil, dass sie stark temperaturempfindlich
sind und bei Überhitzung Über etwa 350G un-,
brauchbar werden.
;r Des weiteren sind diese Elemente feuchtigkeitsempfindlich, was
'4 trota entsprechender Schutsmassnahaen des öfteren im Störungen
\ Anlass gibt.With the previously used · !! With converters made of Seignettesal elements, there is the disadvantage that they are highly temperature-sensitive and become unusable if overheated to more than about 35 ° G.
; r Furthermore, these elements are sensitive to moisture, which is 4 'trota appropriate Schutsmassnahaen often \ in disturbances occasion.
Dee weiteren besteht bei bekannten magnetischen Klβinstmikrofonen der Nachteil, das» sie gegen »agnetische Störfelder, s.B. in der Nahe elektrischer Leitungen, stark brunwieapfindlich sind.Another is known magnetic sound microphones the disadvantage that "they counteract" agnetic interference fields, see B. in the Close to electrical lines that are highly sensitive to brunwi.
Gemass der Erfindungen lassen sich die «Htm genannten Nachteile dadurch beheben, dass in das Mikrofonkleinstgehäuse ein Wandler - urne pieio-elektrischem keramisGheia Material eingebaut wirft* ; Dieses Material Ist gegen Feuchtigkeit und üme unempfindlich.According to the inventions, the disadvantages mentioned can be remedied by the fact that a transducer - urn pieio-electrical keramisGheia material - is built into the micro-microphone housing * ; This material is insensitive to moisture and humidity.
