Abstract

Die Erfindung bezieht sich auf eine Wandlerplatte für elektroakustische Wandler, die aus einer Trägerplatte und einer darauf aufgebrachten Keramikschiebe besteht. The invention relates to a converter plate for electroacoustic transducers consisting of a carrier plate and there is a ceramic slide attached to it.

Aufgabe ist es, die Wandlerplatte trotz der erforderlichen unterschiedlichen Spannungsübertragungsfaktoren so zu dimensionieren, daß dieselbe Platte für Mikrofon, Fernhörer und piezoelektrischen Tonruf verwendet werden kann. Fol­ gende Maße gelten vorzugsweise: Durchmesser der Wand­ lerplatte (⊘₂) 43 mm, Durchmesser der Keramik (⊘₁) 30 mm Dicke der Wandlerplatte (d) 150 µm und Dicke der Keramik (1) 90 µm. The task is to convert the converter plate despite the required different voltage transmission factors dimension that same plate for microphone, telephones and piezoelectric ringing can be used. Fol The following dimensions preferably apply: diameter of the wall lerplatte (⊘₂) 43 mm, diameter of the ceramic (⊘₁) 30 mm Thickness of the transducer plate (d) 150 µm and thickness of the ceramic (1) 90 µm.

Anwendbar in der Fernmeldetechnik. Applicable in telecommunications.
