摘要:
A very small condenser microphone has been developed which exploits materials and methods of construction only recently made available by the post‐war developments in plastics. These techniques have made possible a microphone with extremely regular voltage amplitude and phase responses as functions of frequency and with a reasonably high sensitivity. An analysis is given for the resonance frequencies of a circular membrane stretched over a closed cavity with its center fixed over a small area.
