Abstract

Selon un premier aspect, l'invention concerne un excitateur inertiel (40) pour un élément rayonnant acoustique (42), cet excitateur comprenant un élément massif (44), un élément d'accouplement (46, 56) conçu pour être fixé à l'élément rayonnant acoustique (42) et conçu pour permettre un mouvement par rapport à l'élément massif (44), un moteur pour déplacer l'élément d'accouplement (46, 56) par rapport à l'élément massif, et une suspension (60) pour soutenir l'élément massif par rapport à l'élément d'accouplement. Cette suspension (60) agit dans un plan qui passe en général à travers le centre de masse de l'élément massif, réduisant ainsi tout moment agissant sur le moyen de suspension. Selon un second aspect, l'invention concerne un ensemble excitateur (70) de haut parleur, qui comprend une plaque de base (86) destinée à être fixée à un élément rayonnant acoustique de façon non amovible, et un excitateur (40) fixé à cette plaque de base (86) de façon amovible.
