Abstract

En svingspole-Vibrasjonseksiterer (1) for eksitering av en resonansmembran, omfattende en magnetmontasje som avgrenser en ringspalte (2), en talespolemontasje (5) som er anordnet i ringspalten, en monteringsdel (8) ved hjelp av hvilken eksitereren er montert på membranen og ril hvilken talespole- montasjen er fast festet, og en fjærende opphengning (12) på monteringsdelen og koplet ril magnet- montasjen for å tillate aksial bevegelse av talespolemontasjen (5) i ringspalten, idet arrange- mentet er slik at "fotavtrykket" til den fjærende opphengning er inneholdt innenfor fotavtrykket ril monteringsdelen eller faller sammen med dette.
