Abstract

Die Erfindung betrifft einen elektroakustischen Wandler mit einer Membrane (6), die einen Zentralteil (8) und einen Randteil (7) aufweist und eine an deren Übergangsbereich direkt oder indirekt befestigte Spule (9), die in einen ringförmigen Spalt zwischen zwei Jochteilen (4, 5) ragtThe invention relates to an electroacoustic transducer with a membrane (6) which has a central part (8) and has an edge part (7) and one at its transition region directly or indirectly attached coil (9), which in an annular gap between two yoke parts (4, 5) protrudes

Die Erfindung ist dadurch gekennzeichnet, daß im Raum zwischen dem Zentralteil (8) und dem zugehörigen Jochteil (5) eine mechanische Abstützung (10) im Abstand von der Membrane angeordnet ist.The invention is characterized in that in the space between the central part (8) and the associated yoke part (5) a mechanical support (10) at a distance from the membrane is arranged.

Ausgestaltungen betreffen die Art und Ausbildung der Abstützung und eine analoge Abstützung für den Randteil (7) der Membran (6).
