Abstract

En hornhøyttaler, særlig for å reprodusere basslyd i "public address" systemer, hvor hornet (23) er montert direkte til driverelementet (21) uten mellomliggende kompresjonskammer. Baksiden av driverelementet (21) er dekket av et bakkammer (24) som er laget med vegger av et halvgjennomtrengelig materiale. Veggene kan være perforert eller laget av et "lekkende" materiale, for eksempel celleskum med åpen struktur, eller et fibermateriale. Det "lekkende" bakkammeret vil hindre at det bygges opp for høyt trykk i bakkammeret ved store membranutslag. Hornhøyttaleren er egnet for stabling i grupper på to eller flere, slik at det kan lages en skalerbar lydkilde for gjengivelse av en hvilken som helst del av det frekvensområdet som kan høres av mennesker, for bruk i "public address" eller hi-fi systemer. På grunn av utformingen av bakkammeret, vil hornhøyttalerne kunne stables tett sammen, særlig høyttalere for høye frekvenser med konisk hornutforming. Dermed kan en slik lydkilde som består av en rekke slike tett stablede høyttalere, gi et homogent lydfelt som dekker et bredt område, selv ved høye lydfrekvenser.
