Abstract

Данное изобретение относится к подвижной катушке для громкоговорителей и микрофонов, состоящей из полосы электропроводящей фольги, спирально намотанной виток поверх витка вокруг каркаса катушки. Полоса фольги наматывается так, что её широкая сторона идет параллельно цилиндрической стороне каркаса катушки, чтобы все витки одинаково располагались в магнитном поле. Это изобретение обеспечивает более высокие динамические характеристики, более высокий КПД и более точное преобразование электрических сигналов в звуковые волны в случае громкоговорителей, а также более высокую чувствительность и более точное преобразование звуковых волн в электрические сигналы в случае микрофонов.Международная заявка была опубликована вместе с отчетом о международном поиске.This invention relates to a moving coil for loudspeakers and microphones, consisting of a strip of electrically conductive foil, spirally wound coil on top of the coil around the coil frame. The foil strip is wound so that its wide side runs parallel to the cylindrical side of the coil frame so that all the turns are equally spaced in a magnetic field. This invention provides higher dynamic performance, higher efficiency and more accurate conversion of electrical signals into sound waves in the case of loudspeakers, as well as higher sensitivity and more accurate conversion of sound waves into electrical signals in the case of microphones. The international application was published together with international search.
