The present invention provides a method of an electroacoustic transducer capable of simplifying an assembling process on a lead frame and realizing an automatic assembling work. The method comprises steps of forming pole piece portions (4), forming a lead frame (40) having a plurality of base forming areas thereon, each of the areas having lead terminals (2A, 2B, 2C, 2D) formed therein, forming bases (8) of a synthetic resin on the lead frame (40) by molding so that the pole piece portions (4) are embedded in the bases (8), mounting a coil (10) on the pole piece portions (4) embedded in the bases (8), disposing a support ring (20) and a magnet (12) so as to surround the coil (10), and placing a diaphragm (24) on the support ring (20) to be held thereby, connecting opposite ends (28, 30) of the coil (10) to the lead terminals (2A, 2B, 2C, 2D), cutting off the lead terminals (2A, 2B, 2C, 2D) from the lead frame (40), putting cases (32) on and fixedly joining the same to the bases (8), and subjecting the cut lead terminals (2A, 2B, 2C, 2D) to a forming process. <IMAGE> |
