摘要：A method of manufacturing an electroacoustic transducer which is not changedin its characteristic by heat caused by reflow soldering even if a coil is made of a general-purpose wire. The method of manufacturing the electroacoustic transducer including amagnetic driving portion composed of a core provided upright on a base and a coilwound around the core, comprises setting a height of the coil lower by a height, whichcorresponds to thermal expansion of the coil in reflow soldering, then subjecting the coilto heat processing to thermally expand the coil so that the height of the coil is set to anoptimum height.
