ABSTRACT:
An electric signal transmission transducer employing a ferromagnetic amorphous ribbon and especially an electric signal transmission element and system and an electroacoustic signal conversion system using a ferromagnetic amorphous ribbon. The transmission transducer also provides for applying a magnetic field to the ferromagnetic amorphous ribbon for controlling the electric signal transmission or delay time. Also shown are the electric and magnetic characteristics of ferromagnetic amorphous ribbons after various heat treatments in various magnetic fields.
