Abstract
Improvements in the manufacture of high fidelity loudspeakers, essentially characterized by the fact that the loudspeaker is actuated as an acoustic piston, using a membrane that has a relationship between its rigidity and its weight higher than what is normally achieved with membranes. of paper, for which purpose the formation of the membrane is substantially solid, in any shape advantageously in a solid conical shape, suitably suspended by the known normal means and advantageously with a suspension ring in any material arranged externally at an intermediate point of the membrane solid conical (Machine-translation by Google Translate, not legally binding)
