Sound reproduction method for use in public domain e.g. telephone, involves using sound emissions from front and rear of transducer by front and back mechanical vibratory dissipation of sound waves through front and rear membranes

摘要

The method involves using sound emissions from front and rear of an electro-acoustic transducer (1) by front and rear mechanical vibratory dissipation of sound waves through front and rear membranes. The sound waves are obtained by driver chassiss vibration and are diffracted by adjusting masses of the membranes to provide acoustic fineness and dynamics, and an acoustic phase.
