Description
Предлагаемое изобретение касаетс устройства стекл нной мембраны с ферромагнитным корем дл электромагнитного репродуктора и заключаетс в ее конструктивной разработке.The present invention relates to a device for a glass membrane with a ferromagnetic crust for an electromagnetic reproducer and consists in its constructive development.
Стекл нна мембрана с ферромагнитным корем дл репродукторов электромагнитного типа, согласно чертежу состоит из двух стекл нных квадратных пластин 2, 2, образующих мембрану, каковые пластинки 2, 2 снабжены в центре вырезами. Между кра ми последних укреплен корь 10 электромагнита 7, 8, выполнен ный из ферромагнитного материала в виде тонкого металлического диска. Между стекл нными пластинками 2, 2 помещены металлические прокладки 4 толщиною,The glass membrane with a ferromagnetic core for electromagnetic-type reproducers, according to the drawing, consists of two glass square plates 2, 2 forming a membrane, which plates 2, 2 are provided with cutouts in the center. Between the edges of the latter, the core of the electromagnet 7, 8 is reinforced, made of a ferromagnetic material in the form of a thin metal disk. Between the glass plates 2, 2 are placed metal strips 4 with a thickness
равной толщине кор 10, а с целью осуществить плотное прилегание пластинок equal to the thickness of the core 10, and in order to make the plates fit tightly
. 2, 2 друг к другу между последними проложены , эластичные шайбы 3. Стекл нные Пластинки 2, 2 с укрепленным между ними корем 10 прикреплены винтами 5 к металлической доске 1, снабженной отверстием, в которое пропущен сердечник 8 электромагнита репродуктора.. 2, 2 to each other between the latter are laid, elastic washers 3. Glass Plates 2, 2 with the core 10 fixed between them are fastened with screws 5 to a metal plate 1 equipped with a hole into which the core 8 of the electromagnet of the reproducer is passed.
Во врем работы репродуктора по обмотке электромагнита течет измен ющийс ток, намагничивающий сердечник, а последний, воздейству на корь 10, вызывает колебание стекл нной мембраны, котора и воспроизводит звучани , передаваемые по радио.During the operation of the loudspeaker, a variable current flows through the electromagnet winding, the magnetizing core, and the latter, acting on the measles 10, causes a oscillation of the glass membrane, which reproduces the sound transmitted by radio.
