Electret microphone with simplified electrical connections by printed circuit board mounting |
| abstract |
Abstract of the Disclosure A telephone electret microphone assembly has an electret clamped between a pair of printed circuit boards. The electret conducting surface and printed circuit patterns on the boards have an overlapping arrangement at a planar function. The arrangement connects a capacitor, of which the electret forms part, into an amplifying circuit. - i - |
