Abstract

Die Erfindung betrifft ein Klein-Mikrophon (1), das an der Kleidung oder direkt am Körper, beispielsweise im Haar, getragen wird, mit einer Stirnplatte (9) und einer Bodenplatte (2) und einem dazwischen angeordneten Mantel (3) mit zumindest einer Öffnung, die von jeweils einer Membran (3',3") abgedeckt wird, wodurch im Inneren des Mikrophons ein innerer Hohlraum (7) geschaffen wird.
Die Erfindung ist dadurch gekennzeichnet, daß der innere Hohlraum (7) mittels eines Bauteiles hoher akustischer Impedanz mit einem Ausgleichshohlraum (8) verbunden ist, der gegenüber der Umgebung (11) durch eine schlappe Membran (6) feuchtigkeitsdicht abgeschlossen ist.
Der Bauteil hoher akustischer Impedanz ist bevorzugt ein dünnes Röhrchen.
