Abstract
An electrostatic electroacoustical transducer contains an electrically conductive fixed electrode plate having an active surface with recesses. A conductive or semiconductive flexible diaphragm is disposed at a distance from the active surface of the electrode plate and within the recesses. An insulating device is disposed between the electrode plate and the diaphragm.
Claims11
An electrostatic capacitive transducer comprising:
- an electrically conductive fixed electrode plate having an active surface with recesses formed therein;
- a diaphragm, selected from the group consisting of conductive flexible diaphragms and semiconductive flexible diaphragms, disposed at a distance from said active surface of said electrically conductive fixed electrode plate and within said recesses;
- an insulating device disposed between said electrically conductive fixed electrode plate and said diaphragm;
- and
- a device for detecting a capacitance between said electrically conductive fixed electrode plate and said diaphragm.
