In an electroacoustic converter, center pole and top plate which constitute a magnetic circuit are mechanically abutted against each other by interposing an air gap defining member therebetween. The air gap defining member is a projection provided on the center pole or top plate, otherwise non-magnetic ring-like sleeve covered on the center pole or top plate. An air gap in the magnetic circuit can be precisely defined by the air gap defining member without using any alignment tool in its assemble process.
