Abstract
A readily assembled transducer assembly. The assembly includes a cup-shaped housing for the transducer magnetic structure. The housing has sized slots for receiving the pole piece tips and nesting members for positioning the coil bobbins, the pole pieces and permanent magnet bar within the housing. The cup is placed on a plate of magnetic material so that the pole tips are attracted to the plate and held firmly in place. With the pole tips held, a potting compound may be introduced into the cup cavity. As the compound is hardening, terminals and a cap cover may be applied. When the compound has set, the assembly is removed and is ready for use.
