CONDENSER MICROPHONE HAVING A PLURALITY OF DISCRETE VIBRATORY SURFACES

摘要

The diaphragm of a condenser microphone is broken up into many small pieces so that each attains a natural high frequency resonance above the range of sounds to be picked up with the sum total of the pieces providing an output as great as a single diaphragm with a lower impedance by providing a series of concentric ring contacts wih a diaphragm stretched over the rings, the highest points or ridges of which lie on a convex surface, to break up the diaphragm into annular sections.
