Abstract

Mikrofon magnetyczny, zwłaszcza do niskich częstotliwości akustycznych i infradźwięków, zawierający: układ magnetyczny składający się z dwóch części rdzenia magnetycznego: części zwanej rdzeniem głównym z umieszczoną w nim zwojnicą (5) oraz części zwanej zwornikiem magnetycznym; jedna z części rdzenia jest przymocowana do elastycznej membrany; obie części rdzenia złożone razem tworzą kompletny rdzeń o zamkniętym strumieniu magnetycznym; charakteryzuje się tym, że: pomiędzy rdzeniami znajduje się przerwa tworząca szczelinę magnetyczną; jeden z rdzeni pod wpływem zmian ciśnienia akustycznego oddziałującego na membranę porusza się względem drugiego, powodując zmianę szerokości szczeliny magnetycznej.
