ABSTRACT:
An electric horn, especially adapted for automotive vehicles includes a pole piece and adjusting cap for the driving motor. The pole piece and adjusting cap include a cylindrical shank and an enlarged head including a conical flange. The flange terminates in an annular rim which is in contact with and secured to the horn housing by resistance welding. A magnetic circuit for the motor extends from the pole face of the pole piece and adjusting cap through the shank and the head to the housing and the cross-sectional area for the flux path through the head is at least as great as that in the shank and sufficiently large to avoid undue magnetic saturation. The rim of the enlarged head has a diameter greater than that of the shank and less than the diameter of the housing coil cup to thereby obtain increased stiffness in the connection of the pole piece and adjusting cap with the housing.
