Abstract
Høyttalerkonstruksjon hvor et kjegleformet membran (15) bevirkes til å generere og stråle ut lyd ved hjelp av et samvirke mellom en drlvspole på en spoleform (24) fastgjort til halsen til membranet og en magnetenhet (14) fastgjort til høyttalerens chassis (10). Elektrisk aktivering av drivspolen frembringer en drivkraft som virker på drivspolen for å bevege membranet. For å redusere eller forhindre stråling av lyden fra en frontring (11) på chassiset og en ledeplate på hvilken chassiset er montert, hvilken stråling oppstår fra reaksjonen på drivkraften som virker på magnetenheten, er magnetenheten mekanisk isolert eller dekoblet fra chassiset. Dette tilveiebringes ved å fastgjøre magnetenheten til chassiset ved hjelp av elastiske monteringsinnretninger (14) for å redusere eller forhindre overføring av reaksjonskraften fra roagnet- enheten til chassiset.
