Abstract
An electroacoustic transducer has lead terminals formed of an alloy consisting of 32 to 55% by weight of Ni and a remainder essentially of Fe, and having a crystal grain size of 7.0 or greater. In an electroacoustic transducer, both coil terminals of the coil are connected to the associated lands of the lead terminals, and thermal conduction suppressing sections are provided at proximal end sides of lands of the lead terminals for suppressing thermal conduction.
