Abstract

La présente invention se rapporte à un système de haut-parleur à plaques multidirectionnelles, conçu pour reproduire des sources sonores d'une vaste étendue. Le système de haut-parleur selon l'invention comprend une pluralité de premières plaques de vibration, destinées à reproduire les sons de gammes moyenne et haute par l'entraînement direct d'une bobine mobile, et une seconde plaque de vibration, destinée à reproduire les sons de gamme basse par la force d'entraînement d'une pluralité de parties de circuit magnétique qui lui sont reliées.
