摘要

Improvements in the assembly of the edges of the membranes in high-fidelity loudspeakers essentially characterized by the fact that the edges of the loudspeaker cone are completely smooth, following the general conicity of the loudspeaker, to apply a crown of neutral material from this point of view acoustic as the synthetic foam endowed with great elasticity and in fixing the edge of this crown between the wiggle of the frame of the speaker thus leaving the membrane of the speaker free to undergo forward and backward movements as a piston on its elastic support.
