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.A pivot coil vibration exciter (1) for excitation of a resonant membrane, comprising a magnetic assembly defining a ring slot (2), a voice coil assembly (5) disposed in the ring slot, a mounting portion (8) by means of which the exciter is mounted on the membrane, and and the resilient suspension (12) on the mounting member and coupled to the magnetic assembly to allow axial movement of the voice coil assembly (5) in the ring slot, the arrangement being such that the "footprint" of the resilient suspension is contained within the footprint of the mounting member or coincides with it.
