Claims (13)

  1. 20
    1. System til gengivelse af lyd omfattende: i det mindste en driver (12; 120, 122; 152; 202), som har et første og andet lydoutput i forskellige retninger, en lydbarriere (14; 102; 154; 204, 216, 218), som afgrænser en tragtpassage, som har en første (22; 110, 112; 160, 162; 204, 212) og anden (24; 104; 154) tragtsektion med en halsende og en åben ende imellem den første og den anden tragtsektion, hvor den i det mindste ene driver er monteret på lydbarrieren i umiddelbar nærhed af en grænse ved den første og den anden tragtsektion, således at det første lydoutput bæres ind i den første tragtsektion (22; 110, 112; 160, 162; 204, 212) og det første og det andet lydoutput bæres ind i den anden tragtsektion (24; 104; 154).
  2. 2. System ifølge krav 1, hvorved det første og det andet lydoutput strækker sig i alt væsentligt i modsatte retninger.
  3. 3. System ifølge krav 1, hvorved lydbarrieren (14; 102; 154; 204, 216, 218) afgrænser en sammenhængende tragtpassage, der omfatter en første (22; 110, 112; 160, 162; 204, 212) og anden tragtsektion (24; 104; 154).
  4. 4. System ifølge krav 1, hvorved den i det mindste ene driver (168) er monteret på en midterdel af lydbarrieren.
  5. 5. System ifølge krav 4, hvorved lydkommunikationen til tragtpassagen til det andet lydoutput er tilvejebragt ved hjælp af en åbning (48) i lydbarrieren.
  6. 6. System ifølge krav 1, hvorved tragtpassagen er kontinuerligt bueformet.
  7. 7. System ifølge krav 1, hvorved tragtpassagen omfatter en række retlinede banedele. 21
  8. 8. System til gengivelse af lyd ifølge et af kravene 1 til 7, omfattende: i det mindste to drivere (120,122; 152), som hver har et første og et andet lydoutput i forskellige retninger, en lydbarriere, som afgrænser en tragtpassage, som har et par af første (160, 162; 204, 212) tragtsektioner og en anden tragtsektion (154) med et par halsender og en åben ende imellem den første og den anden tragtsektion, og hvor driverne (120, 122; 152) er således monteret på lydbarrieren, at deres respektive første lydoutput bæres i de første tragtsektioner (160, 162; 204, 212), og deres første og et andet lydoutput bæres i den anden tragtsektion (154).
  9. 9. System ifølge krav 8, hvorved det første og det andet lydoutput strækker sig i hovedsagen i modsatte retninger.
  10. 10. System ifølge krav 8, hvorved lydbarrieren afgrænser en sammenhængende tragtpassage, som omfatter den første (160, 162; 204, 212) og anden tragtsektion (154).
  11. 11. System ifølge krav 8, hvorved driverne (152) er monteret på midterdele af lydbarrieren i umiddelbar nærhed af grænser imellem den første (106, 162) og anden tragtsektion (154).
  12. 12. System ifølge krav 11, hvorved lydforbindelsen til tragtpassagen for det andet lydoutput fra driverne tilvejebringes ved hjælp af åbninger i lydbarrieren.
  13. 13. System ifølge krav 8, hvorved tragtpassagen har en række retlinede banedele.
