Abstract

473,672. Magnets. CONTINENTAL MOTORS CORPORATION. April 14, 1936, No. 6086/37. Convention date, April 13, 1935. Divided out of 473,648. [Class 35] [Also in Group XXXIX] A magnet system, particularly for a moving-coil loud-speaker, microphone, or the like, comprises a yoke 3, a pole-plate 2 and a centre polepiece constructed of terminal portions 6, 7 of mild steel and an intermediate permanent magnet portion 31. As shown, the cross-sectional area of the portion 7 adjacent the air gap is less than that at the plane of contact with the magnet 31 which has axial length less than the average diameter of sections at right-angles to the axis. The poleplate 2 is secured to the yoke 3 by clamps 40.
