Description

PATENTKRAV 1. Højttaler surround system til brug i forbindelse med et fjernsyn, omfattende mindst en venstre højttaler, mindst en højre højttaler og en centerhøjttaler, hvor centerhøjttaleren er delt op i en høj- og mellemffekvenshøjttaler og en bashøjttaler, kendetegnet ved, at høj- og mellemfrekvenshøjttaleren er anbragt oven på fjernsynet eller er indbygget i dette, medens bashøjttaleren er anbragt og/eller indkoblet på en sådan måde, at lyden fra bashøjttaleren er forsinket i forhold til lyden fra høj- og mellemfrekvenshøjttaleren, eksempelvis ved at bashøjttaleren er anbragt bag fjernsynet. 2. Højttalersystem ifølge krav 1, kendetegnet ved, at baskabinettet er anbragt mindst ca. 30 cm bag høj - og mellemtonekabinettet. 3. Højttalersystem ifølge krav 1, kendetegnet ved, at forsinkelsen af signalet fra baskabinettet er tilvejebragt ved hjælp af et forsinkelseskredsløb i tilledningerne til baskabinettet (4b). 4. Højttalersystem ifølge krav 3, kendetegnet ved, at forsinkelseskredsløbet tilvej ebringer en forsinkelse på op til ca. 2 ms.. 5. Højttalersystem ifølge et af de foregående krav, kendetegnet ved, at et forhåndenværende filter bidrager til forsinkelse af signalet fra baskabinettet (4b). 6. Højttalersystem ifølge et af de foregående krav, kendetegnet ved, at man kan justere faseforholdene ved at ændre lavpas fil treringen i lavffekvenskabinettet. 7. Centerhøjttaler der indgår i et højttaler surround system til brug i forbindelse med et fjernsyn omfattende mindst en venstre højttaler, mindst en højre højttaler og centerhøjttaleren, som er delt op i en høj- og mellemfrekvenshøjttaler, og en bashøjtta- ler, kendetegnet ved, at høj- og mellemffekvenshøjttaleren er anbragt ovenpå fjernsynet eller er indbygget i dette, medens bashøjttaleren er anbragt og evt. er indkoblet på en sådan måde, at lyden fra bas er forsinket i forhold til lyden fra høj- og mellemfrekvenshøjttaleren, eksempelvis ved at bashøjttaleren er anbragt bag fjernsynet.1. Speaker surround system for use in connection with a television, comprising at least one left speaker, at least one right speaker and one center speaker, wherein the center speaker is divided into a high and medium power speaker and a base speaker, characterized in that the intermediate frequency speaker is placed on top of the television or is built into it, while the bass speaker is arranged and / or switched on in such a way that the sound from the bass speaker is delayed relative to the sound from the high and medium frequency speaker, for example by the bass speaker being placed behind the remote. Speaker system according to claim 1, characterized in that the base housing is arranged at least approx. 30 cm behind the high - and mid - tone cabinet. Speaker system according to claim 1, characterized in that the delay of the signal from the base cabinet is provided by means of a delay circuit in the leads to the base cabinet (4b). Speaker system according to claim 3, characterized in that the delay circuit provides a delay of up to approx. Speaker system according to one of the preceding claims, characterized in that an existing filter contributes to delay of the signal from the base cabinet (4b). Loudspeaker system according to one of the preceding claims, characterized in that the phase conditions can be adjusted by changing the low pass filtering in the low frequency cabinet. A center speaker included in a surround-speaker system for use with a television comprising at least one left speaker, at least one right speaker and the center speaker divided into a high and medium frequency speaker, and a bass speaker, characterized by, that the high- and medium-power speaker is placed on top of the television or is built into it, while the bass speaker is positioned and possibly. is switched on in such a way that the sound from bass is delayed relative to the sound from the high and medium frequency speaker, for example by the bass speaker being placed behind the television.
