Description
Уже известны телефоны с применением крестообразного пол ризованного электромагнита, на центральном полюсе которого прикреплена срелней своей частью мембрана, при чем кра этой мембраны свободны. Предлагаемое изобретение заключаетс в конструктивной разработке названного выше телефона.Phones with the use of a cross-shaped polarized electromagnet are already known, on the central pole of which the membrane is attached with its middle part, and the edges of this membrane are free. The present invention consists in the constructive development of the above-named phone.
На схематическом чертеже фиг. 1 изображает вертикальный разрез телефона; фиг. 2-вид его сверху.In the schematic drawing of FIG. 1 shows a vertical section of the telephone; FIG. 2 - view it from above.
Устройство предлагаемого телефона заключаетс в следующем: к штампованному футл ру 1 винтами Л, Л крепитс кругла розетка v, к которой винтами прикрепл етс крестообразный пол ризованный магнит Nff, к среднему полюсу 5 которого средней своей частью укреплена мембрана А, при чем кра последней свободны. С целью улучшени действи телефона концу Е среднего полюса 5 пол ризованного магнита придана полушарова форма. .The device of the proposed phone is as follows: a round socket V is attached to a stamped case 1 with screws L, L to which a cross-shaped polarized magnet Nff is attached with screws, to the middle pole 5 of which membrane A is fixed with its middle part, with the latter edges free. In order to improve the effect of the phone, the end E of the middle pole 5 of the polarized magnet is given a hemispherical shape. .
Предмет изобретени .The subject matter of the invention.
Телефон с применением крестообразного пол ризованного электромагнита, на центральном полюсе которого укреплена средней своей частью мембрана, при чем кра этой мембраны свободны, отличающийс тем, что концу Е центрального полюса S, на котором крепитс мембрана А, придана выпукла , например, полушарова форма.A telephone using a cross-shaped polarized electromagnet, at the central pole of which the membrane is fixed with its middle part, is free at the edges of this membrane, characterized in that the end E of the central pole S, on which membrane A is attached, is given a convex shape, for example, hemisphere.
