seller note Authentique et rare SONOTONE / CORNET ACOUSTIQUE en cuivre - XVIIIe s.
Les premiers amplificateurs d’écoute, appelés tubes ou cornets acoustiques étaient fabriqués en cuivre. Leur système purement mécanique, inspiré du téléphone de Graham Belle breveté en 1876 leur permettait d'amplifier le son jusqu’à 100 décibels
