摘要
The Parent Patent No.2828520 described an electrodynamic sound reproduction system for high-qualtiy music fidelity. The broadband differential amplifier, required for this system, can be saved by replacing the single loudspeaker by a field of many small, independently controlled diaphragms, made of expanded polystyrene, and arranged along a convex contour and forced to perform synchronous vibrations. A pulse width modular of much lower cost than the broadband differential amplifier, consists of a Schmitt trigger, with one pulse edge derived from the comparison of the input voltage with a sawtooth voltage, and the other pulse edge fixed by an external pulse.
