Abstract
An electrostatically operating electroacoustic transducer, operating as a sound receiver and configured to be mounted in a microphone capsule, has an electrode and a diaphragm connected to one another at a spacing from one another by a spacer ring, wherein on the electrode at least one first electric resistor is arranged which is connected to a power supply during operation of the microphone. The resistor is heated to prevent condensation of water vapor, and this improves the resistance of the microphone against ambient humidity.
