Title
(EN) DIPOLE AND MONOPOLE SURROUND SOUND SPEAKER SYSTEM
(FR) ENCEINTE SATELLITE DIPOLE ET MONOPOLE
Abstract
(EN)
A speaker system utilizes dipole speaker drivers (145, 150) in conjunction with monopole speaker drivers (125, 130) in a listening area to disperse a surround sound effect to a listener. The dipole speaker drivers (145, 150) are physically mounted on top of the front left and right speakers and are angled in a way that the surround information is delivered to the listener (120) via wall (115)/room reflections. By reflecting the sound off the walls, the system provides a delayed diffuse audio signal from the dipole speakers (145,150), enhancing the surround effect.
(FR)
L'invention concerne une enceinte satellite dipole et monopole utilisant des haut-parleurs individuels dipoles associés à des haut-parleurs individuels monopoles dans une zone d'écoute pour procurer un effet son d'ambiance à un auditeur. Les haut-parleurs individuels dipoles sont physiquement montés au sommet des haut-parleurs avant à gauche et à droite et forment un angle de telle manière que les données son d'ambiance sont cédées à l'auditeur par des réflexions mur/salle. La réflexion du son sur les murs permet à l'enceinte de céder un signal audio diffus retardé à partir de haut-parleurs dipôles, ce qui améliore l'effet son d'ambiance.
