ABSTRACT:
An automated method for winding a coil of an electroacoustic transducer utilizes a support member that has a frusto-conical projection for receiving an outer pole tip. The frusto-conical configuration assures that, upon completion of a coil winding about the pole, there is an exposed recess around the periphery of the pole tip. This is accompanied by an end surface of the winding being coplanar with the corresponding end surface of the pole tip. Maximized performance for the transducer may then be realized.
