Description

Обычно угольные микрофоны с металлическими электродами имеют характеристику, не вполне подход щую дл  передачи широкого спектра частот широковещани .Usually, carbon microphones with metal electrodes have a characteristic that is not quite suitable for transmitting a wide range of broadcast frequencies.

Целью изобретени   вл етс  создание микрофона дл  передачи широкого спектра частот. Предлагаемый микрофон состоит из чашки 1, несущей коническую мембрану 2, завальцованную к части / кра ми крышки 3. В днище 4 микрофона вставлен металлический электрод 5, образующий при помощи войлочного цилиндра 6  чейку дл  засыпки.The aim of the invention is to provide a microphone for transmitting a wide range of frequencies. The proposed microphone consists of a cup 1, carrying a conical membrane 2, rolled up to the part / edges of the cover 3. A metal electrode 5 is inserted into the bottom 4 of the microphone, forming a cell for filling with the help of a felt cylinder 6.

Днище 4 крепитс  к чащке 1 винтами 7. Электрод 5 крепитс  к днищу 4 гайкой 8 и изолирован от него прокладками 9.The bottom 4 is fastened to the lash 1 with screws 7. The electrode 5 is attached to the bottom 4 by a nut 8 and is insulated from it by gaskets 9.

Зар дка микрофона производитс  через центральное отверстие в электроде 5, закрываемое винтом 10.The microphone is charged through a central opening in the electrode 5, covered by a screw 10.

Мембрана 2 выдавливаетс  из алюмини  или красной меди, толщиной около 3,05 мм. При алюминии конус покрываетс  угольной суспензией, а при латуни золотитс , равно, как и кратер электрода 5.The membrane 2 is extruded from aluminum or red copper, about 3.05 mm thick. With aluminum, the cone is covered with coal slurry, and with brass it gilds, as does the crater of electrode 5.

Мембрана внедрена верщиной в  чейку и оперта боковой поверхностью о край войлочного цилиндра.The membrane is embedded in the cell and supported by the side surface of the felted cylinder.

Предмет изобретени .The subject matter of the invention.

Угольный микрофон, отличающийс  тем, что коническа  мембрана внедрена вершиной в  чейку с коническим кратером и оперта боковой поверхностью о внутренний край цилиндра, ограничивающего засыпку. Е авторскому свидетельству А. № 55063 Е. НикифороваA carbon microphone, characterized in that the conical membrane is implanted with the apex in a cell with a conical crater and supported by a side surface on the inner edge of the cylinder bounding the filling.
