Has high impedance speaker with reed suspended between pole pieces, drives paper cone with a stylus, and is directly driven by a single ended collector, without an audio output transformer. One of several contemporary GE transistor radio models do employ this kind of speaker which was originally used in the 1920's because of it's high efficiency and high impedance.
