| titleOfInvention | Alcoacoustic transducer produced in slice form |
| abstract | A capacitive electroacoustic transducer (10) comprising: (a) an electrically insulative substrate (12); (b) a layer of conductive material disposed on a portion of a top surface of the substrate forming a first electrode (16) of the transducer; (c) a conductive diaphragm (22) forming a second electrode of the transducer, the diaphragm being deflectable in relation to the first electrode; (d) a diaphragm mounting ring (18) made of an electrically conductive material disposed about a periphery of the top surface of the substrate and separated from the first electrode for electrically and physically separating the first and second electrodes in a spaced relationship s as to constitute a capacitor, such that an electrical field formed between the first and second electrodes varies in relationship with deflections of the second electrode to permit conversion between electrical and acoustic signals, the ring being thicker than the first electrode by an amount corresponding to a desired separation between the diaphragm and the first electrode and the ring being bonded to a periphery of the diaphragm; and (e) a compensation ring (17) disposed on a bottom surface of the substrate in an area corresponding to the diaphragm mounting ring on the top surface of the substrate, the compensation ring having a similar physical size and being made of similar material as the diaphragm mounting ring. 3581 כ" ו בכסלו התשס" ג - December 1, 2002 3582 כ" ו בכסלו התשס" ג - December 1, 2002 |
