Abstract

L'invention concerne un haut-parleur dynamique de type hybride. Selon la présente invention, au moins deux embouchures sont formées dans une portion de montage d'un cadre pourvu d'un haut-parleur à génération de gamme étendue, et chaque embouchure est équipée de moteurs à armature équilibrée espacés les uns des autres, de telle sorte qu'il est possible de mettre en œuvre un haut-parleur à quatre voies ou plus, ainsi qu'un haut-parleur à trois voies comprenant un haut-parleur à génération de gamme étendue, produisant ainsi un effet capable de subdiviser et de reproduire divers sons aigus.
