- LYDSYSTEM MED FORBEDRET JUSTERBAR RETNING S VIRKNING Krav1. Lydsystem, der omfatter mindst én højfrekvenstransducer (1) og mindst én midtfrekvenstransducer (4) samt drejelige lukkere (6), der reagerer på en lydemission fra højfrekvenstransduceren (1) for at producere en retningsstyret lydemission fra højfrekvenstransduceren (1) langs en valgt vinkelsektor, kendetegnet derved, at den er konfigureret, så midtfrekvenstransduceren (4) og højfrekvenstransduceren (1) sender over et almindeligt frekvensområde, og den omfatter mindst ét kontrolmodul af typen med digital signalprocessor, som reagerer på et signal til højfrekvenstransduceren (1) og på et signal til midtfrekvenstransduceren (4) på en sådan måde, at der i det almindelige frekvensområde anvendes mindst en størrclscsparamctcr på højfrekvenstransduceren (1) og/eller på midtfrekvenstransduceren (4) samt mindst én faseparameter på højfrekvenstransduceren (1) og/eller på midtfrekvenstransduceren (4), så der dannes en retningsstyret lydemission for parret, der udgøres af højfrekvenstransduceren (1) og midtfrekvenstransduceren (4) langs det samme vinkelområde som den retningsvirkning, der dannes af de drejelige lukkere (6).
- 2. Lydsystem i henhold til krav 1, kendetegnet derved, at de drejelige lukkere (6) og kontrolmodulet af DSP-typen er konfigureret, så de hver genererer en forekomst af lydbølgerne ved et lydniveau, der er mere eller mindre konstant i nævnte vinkelområde, hvor de drejelige lukkere (6) og kontrolmodulet af DSP-type er konfigureret på en sådan måde, at de dæmper lydbølgerne ved alle vinkler uden for det nævnte valgte vinkelområde ved en dæmpning på mere end 6 dB i forhold til det maksimale lydniveau i nævnte valgte vinkelområde.
- 3. Lydsystem i henhold til enten krav 1 eller 2, kendetegnet derved, at det er konfigureret, så det almindelige frekvensområde er variabelt afhængigt af retningen af de drejelige lukkere (6).
- 4. Lydsystem i henhold til ethvert af de forrige krav, kendetegnet derved, at det omfatter mindst to midtfrekvenstransducere (4) og mindst én højfrekvenstransducer (1), og hvor midtfrekvenstransduceme (4) placeres på hver side af højfrekvenstransduceren (1).
- 5. Lydsystem i henhold til ethvert af de forrige krav, kendetegnet derved, at det omfatter et hus (7), der mindst delvist omgiver én aflukkerne (6), hvor mindst én af nævnte lukkerne har en flade, der er rettet til at møde en lydstrøm, der udsendes af nævnte højfrekvenstransducer (1), og en flade, der er rettet væk fra den lydstrøm, der udsendes af nævnte højfrekvenstransducer (1), hvor huset (7) danner en forhindring foran fladen på lukkeren (6), som er rettet væk fra den lydstrøm, der udsendes af højfrekvenstransduceren (1), for at beskytte nævnte flade mod stød fra fremmedlegemer.
- 6. Lydsystem i henhold til det forrige krav, kendetegnet derved, at mindst én af nævnte midtfrekvenstransducere (4) omfatter en mobil membran, der har en hovedsageligt konisk form, og huset (7) på nævnte mindst én lukker (6) er formet, så den går i indgreb med en del af den hovedsageligt koniske form af membranen.
- 7. Lydsystem i henhold til ethvert af de forrige krav, kendetegnet derved, at det udgør et mobilt højttalersystem.
- 8. Lydsystem i henhold til krav 4, kendetegnet derved, at det omfatter mindst to lavfrekvenstransducere (5), og nævnte mindst to lavffekvenstransducere (5) er placeret på hver side af en enhed, der udgøres af nævnte mindst én højfrekvenstransducer (1) og nævnte mindst to midtfrekvenstransducere (4).
- 9. Lydsystem i henhold til ethvert af de forrige krav, kendetegnet derved, at det omfatter mindst én bølgeleder (2), der bærer lydbølger, der udsendes af højfrekvenstransduceren (1).
- 10. Lydsystem i henhold til krav 4, kendetegnet derved, at det omfatter en åbning (3) hvorigennem de lydbølger, der produceres af højfrekvenstransduceren (1), udsendes, hvor nævnte mindst to midtfrekvenstransducere (4) er placeret på hver side af åbningen (3).
