AB  - The manner in which modern microphone and telephone receivers, as currently used in hearing aids and the like, has 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 indicated by consideration of their equivalent circuit, and illustrative data is given on typical microphones and receivers including a new unit only 0.375 in. long, 0.220 in. wide and 0.160 in. thick.
