History and Current Status of Miniature Variable-Reluctance Balanced-Armature Transducers

Document Thumbnail

The manner in which modern microphone and telephone receivers, as currently used in hearing aids, have evolved from early telephone receivers is described. The occluded volume of a typical unit is less than one-quarter inch cube. The manner by which a reasonably flat response is secured from variable-reluctance microphones is shown by their equivalent circuit. Illustrative data is given on typical microphones and receivers.
