Abstract
Improvements in the acoustic part of the loudspeakers, essentially characterized by the fact that the fixed connection of the central mouth of the cone to the moving coil is effected by means of a neck of the material itself, that the constituent membrane of the cone, in whose neck it is practically surrounds at least one transverse undulation of a flexible type in order to achieve in the cone a limited selection of the high-pitched sounds to be damped, by said flexible circular zone, most of the high-frequency vibrations produced by the sliding of the mobile coil (Machine-translation by Google Translate, not legally binding)
