  • Electroacoustic transducer
    Patent number: 6510231
    Abstract: An electroacoustic transducer based on the capacitor principle includes an essentially rigid electrode and a flexible electrode constructed as a diaphragm. In the central areas of the electrodes the distance between the diaphragm and the rigid electrode is smaller than in the edge areas thereof. The transducer may include a resonator attachment. The diaphragm is deformed into a cone shape or truncated cone shape. The rigid electrode has in the central area thereof an at least essentially circular-cylindrical projection, wherein the diaphragm rests against this projection, for example by a nipple attached to the resonator attachment.
    Type: Grant
