A loudspeaker cone body made of plastic includes a base carrier material and a filler material. The base carrier material is selected to optimize overall flow, weight and stiffness. The filler material may be a nanomaterial that provides for adjustment of process and acoustic related characteristics in the loudspeaker cone body that become relevant when the loudspeaker cone body is operated in a loudspeaker. Acoustic related characteristics that may be adjusted include a stiffness to weight ratio and an acoustic damping of the loudspeaker cone body. A predetermined weight percent of the filler material may be combined with the base carrier material to obtain repeatable desired acoustic related characteristics. The acoustic related characteristics may be adjusted by changing the predetermined weight percent of the filler material.

L'invention concerne un corps de cône de haut-parleur en plastique qui comprend un matériau support de base et un matériau de remplissage, le premier assurant globalement flux, poids et rigidité, et le second pouvant être un nanomatériau d'ajustement des caractéristiques fonctionnelles et acoustiques connexes dans ledit corps, lorsque les caractéristiques en question deviennent pertinentes si ce corps est utilisé dans un haut-parleur. Les caractéristiques acoustiques connexes considérées peuvent être, par exemple, le rapport rigidité/poids et l'amortissement acoustique du corps décrit. Il est possible de combiner un pourcentage de poids préétabli du matériau de remplissage avec le matériau support de base pour établir des caractéristiques acoustiques connexes spécifiques, reproductibles, lesquelles peuvent être ajustées par modification du pourcentage de poids préétabli du matériau de remplissage.
