Sound purification and amplification device which amplifies sounds produced by an acoustic signal restitution device incorporating at least two transducers, includes a small metal alloy dish

摘要

A sound purification and amplification device able to amplify sounds produced by an acoustic signal restitution device incorporating at least two transducers, whilst attenuating electromagnetic phenomena and parasitic acoustics, includes a small metal alloy dish (1). An Independent claim is also included for an acoustic assembly incorporating this purification and amplification device.
