Claims (6)

  1. Vorrichtung zur Schallwiedergabe mit einer Stereoverstärkervorrichtung (3) aus zwei links und rechts genannten Signalen (61, 62) von einer beliebigen stereophonen Emissionsquelle (1) und mehreren Lautsprechern (4, 9), die in zwei Gruppen angeordnet sind, wobei sich eine (9) links und die andere (4) rechts von der Hörachse befindet und jeweils das entsprechende verstärkte linke Signal (8) und das rechte Signal (7) empfängt, dadurch gekennzeichnet, daß die Anzahl der Lautsprecher (4, 9) geradzahlig ist, wenigstens gleich vier, wobei alle Emissionsflächen der Lautsprecher (4, 9) entlang einer gekrümmten, fortlaufenden Fläche (5) angeordnet sind, und daß die Lautsprecher paarweise entlang vertikalen oder im wesentlichen vertikalen Achsen (zz') angeordnet sind und die jeweiligen Entfernungen sowohl in der Höhe als auch in der Breite zwischen den Lautsprechern (4, 9) gemäß ihrer Dimension und derjenigen des Hörvolumens festgelegt werden und jeder Lautsprecher (4, 9) mit einem eigenen Verstärker (10) verbunden ist, der an diese Lautsprecher alle Frequenzen des empfangenen Signals überträgt, wobei das Signal vorher in so viele Wege (12) durch eine Weiche (2) aufgeteilt wird, wie es Lautsprecher gibt.
  2. Vorrichtung zur Schallwiedergabe nach Anspruch 1, dadurch gekennzeichnet, daß sie einen Modulator (11) umfaßt, der für jeden linken und rechten Kanal nach Integration wenigstens des dem Kanal entsprechenden Signals (6), das von der Emissionsquelle (1) herrührt, einerseits dieses auf jeden Ausgang (12) der Wege der Weiche (2) entsprechend den Lautsprechern des gleichen Kanals in Abhängigkeit vorgegebener Schwellen zum Öffnen eines oder mehrerer Ausgänge (12) verteilt und andererseits gemäß dem Signal die Verstärkung jedes der an diese adressierten Signale unter Beibehaltung der Phase und der Frequenzen dieses moduliert.
  3. Vorrichtung zur Schallwiedergabe nach Anspruch 1, dadurch gekennzeichnet, daß sie einen Modulator (11) umfaßt, der nach Integration des empfangenen allgemeinen Signals (61, 62) der Emissionsquelle (1) einerseits dieses auf jeden Ausgang (12) der Wege der Weiche (2) in Abhängigkeit vorgegebener Schwellen zum Öffnen eines oder mehrerer Ausgänge (12) verteilt und andererseits gemäß dem allgemeinen Signal die Verstärkung jedes der an diese adressierten Signale unter Beibehaltung der Phase und der Frequenzen dieses moduliert.
  4. Vorrichtung zur Schallwiedergabe nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß sie sechs Lautsprecher umfaßt, von denen die zwei linksseitigen (9) und die zwei rechtsseitigen (4) jeweils das linke Signal (8) und das rechte Signal (7), das ihnen entspricht, empfangen, und die zwei zentral gelegenen bei gleichem Abstand (d) von den seitlichen beiden Gruppen gleichzeitig das linke und das rechte Signal empfangen.
  5. Vorrichtung zur Schallwiedergabe nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß sie acht Lautsprecher umfaßt, die in zwei Gruppen zu vier aufgeteilt sind, wobei vier links (9) und vier rechts (4) sind, die jeweils ein Quadripol bilden und symmetrisch in bezug auf die Mittelebene (xx') angeordnet sind.
  6. Vorrichtung zur Schallwiedergabe nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß die Lautsprecher alle identisch sind und so ausgewählt sind, daß ihr Frequenzbereich für die Wiedergabe zwischen 100 Hz und 104 Hz liegt.
