Claims (15)

1. Højttaler, der omfatter: et driverelement (21) med en membran, et horn (23), der er anbragt direkte på forsiden af driverelementet uden et mellemliggende trykkammer, hvor hornet har en akustisk impedans; og et bagkammer (24), der omgiver driverelementet på bagsiden af driverelementet, kendetegnet ved, at bagkammeret har en væg, der er fremstillet af et semipermeabelt materiale, som er indrettet til at tillade luft ved et statisk tryk at passere, men som stadig tilvejebringer akustisk modstand, samtidig med at man forhindrer opbygningen af højt lufttryk i bagkammeret ved store udsving af membranen, hvor bagkammeret har en akustisk impedans, der stemmer overens med den akustiske impedans af hornet inden for en aktiv båndbredde af hornet.
2. Højttaler ifølge krav 1, hvor væggen af bagkammeret (24) er fremstillet af et perforeret materiale.
3. Højttaler ifølge krav 1, hvor væggen af bagkammeret (24) er fremstillet af et skum eller et tæt fibermateriale.
4. Højttaler ifølge krav 3, hvor væggen af bagkammeret (24) er fremstillet af celleskum med en åben struktur.
5. Højttaler ifølge et hvilket som helst af de foregående krav, hvor bagkammeret (24) har to eller flere vægge af et semipermeabelt materiale.
6. Højttaler ifølge et hvilket som helst af de foregående krav, der indbefatter en portion af akustisk dæmpningsmateriale, som er anbragt indeni bagkammeret (24).
7. Højttaler ifølge krav 3, hvor et beskyttende hus (34) af perforeret metal eller plast dækker bagkammeret (24).
8. Højttaler ifølge et hvilket som helst af de foregående krav, hvor hornet har en i det væsentlige konisk form, elle hvor hornet er foldet.
9. Højttaleranordning, kendetegnet ved, at højttaleranordningen indbefatter et antal højttalere ifølge et hvilket som helst af kravene 1-8, som er stablet tæt sammen.
10. Højttaleranordning ifølge krav 9, hvor hornet for hver af højttalerne har en i det væsentlige konisk form.
11. Højttaleranordning ifølge krav 10, hvor frie luftåbninger på hornene for antallet af højttalere er anbragt sammen for at tillade generering af et blødt akustisk bølgemønster fra højttaleranordningen.
12. Højttaleranordning ifølge et hvilket som helst af kravene 9-11, der indbefatter to højttalere, som er anbragt sammen.
13. Højttaleranordning ifølge et hvilket som helst af kravene 9-11, der indbefatter tre højttalere, som er anbragt sammen.
14. Højttaleranordning ifølge krav 10, hvor den koniske form af hornene beskrives ved en åbningsvinkel i området fra 5° til 120°, fortrinsvis i området fra 25° til 45°.
15. Højttaleranordning ifølge et hvilket som helst af kravene 9-14, hvor hver af antallet af højttalere indbefatter et hus, der tjener til beskyttelse, og hvor i det mindste en væg, der danner del af huset, også tjener som en væg, der danner hornet.
