Abstract
A condenser microphone, including at least one diaphragm, at least one electrode assigned to the diaphragm, comprising at least one ring-shaped insulator holding the electrode, comprising at least one diaphragm ring holding the diaphragm, and a holding ring holding the components mentioned. The mechanical and electrical properties of the condenser microphone are improved where the holding ring includes ceramic material. Preferably, the diaphragm ring and/or the ring-shaped insulator also consist(s) of ceramic material. With further preference, the ceramic material is zirconium oxide.
Claims10
1-7. (canceled)
A condenser microphone, comprising:
- at least one diaphragm;
- at least one electrode associated with the diaphragm;
- at least one annular insulator holding the electrode;
- at least one diaphragm ring holding the diaphragm;
- and
- a retaining ring that in cooperation with the annular insulator secures the diaphragm ring, the diaphragm, and the electrode;
- wherein the retaining ring includes a ceramic material.
The condenser microphone of claim 1, wherein both the diaphragm ring and the annular insulator include ceramic materials, which may be the same or different.
The condenser microphone of claim 1, wherein the diaphragm ring and the annular insulator are fastened together by means of screws.
The condenser microphone of claim 1, comprising two electrodes, each electrode being held by a different annular insulator, with the annular insulators being secured by two ceramic retaining rings connected to one another using screws so that the end faces of the two electrodes are disposed opposite one another.
The condenser microphone of claim 1, comprising two electrodes, both electrodes being held by a common annular insulator so that the end faces of the two electrodes are disposed opposite one another.
The condenser microphone of claim 1, comprising two electrodes, both electrodes being held by a common ceramic retaining ring so that the end faces of the two electrodes are disposed opposite one another.
The condenser microphone of claim 1, wherein the ceramic material is zirconium oxide.
