Abstract

En sammensatt høyttaler innbefatter en akustisk strålende første membran og en akustisk strålende andre membran. De første og andre membranene er vesentlig koaksiale og minst en del av den andre membranen er plassert radielt utover fra den første membranen. Det er en spalte plassert mellom den første og andre membranen, og en forsegling er tilveiebrakt i spalten for å hindre passasje av luft gjennom spalten. Ved å tilveiebringe forseglingen løser oppfinnelsen problemet med akustisk turbulent luftstrøm gjennom spalten.
