Abstract

A microphone or loudspeaker having a magnet system which comprises an annular permanent magnet and pole plates which are arranged one on each side of the magnet and the first of which is rigidly connected to a centrally arranged soft-iron core, which together with the second pole plate forms an effective air-gap. The casing serves as a centering sleeve and hence is provided with abutment members, preferably abutments studs, which are arranged on different levels and one of which may be in the form of a fitting edge. The various component parts are stacked in the centering sleeve, which is a simple operation in mass manufacture.
