Abstract

Ein Richtmikrofonsystem (1,29) weist zwei Membrane (5A,5B) auf, die einerseits jeweils über ein Luftvolumen (7A,7B) mit einer von zwei räumlich getrennten Schalleinlassöffnungen (9A,9B) akustisch verbunden sind und andererseits über ein drittes Luftvolumen (11) miteinander akustisch verkoppelt sind, sowie Mittel (13,19A,19B) zum Erzeugen mindestens eines Ausgangssignals des Richtmikrofons (1,25,33) aus der Schwingung einer der beiden Membrane (5A,5B) auf.

A directional microphone system (1, 29) has two membranes (5A, 5B), which are acoustically connected via an air volume (7A, 7B) to one of two spatially separated sound inlet openings (9A, 9B) and via a third air volume (FIG. 11) are acoustically coupled together, and means (13, 19A, 19B) for generating at least one output signal of the directional microphone (1, 25, 33) from the oscillation of one of the two diaphragms (5A, 5B).
