Gabatar da na'urorin lantarki a cikin amplifier

Babban yanayin ya kasance bayyanar a cikin motar mataimakan lantarki da yawa waɗanda ke cire wani ɓangare na buƙatun daga direba. Wannan kuma ya shafi injin amplifiers.

Idan ya zama dole a birki cikin gaggawa, ba duk direbobi ke aiki a kan fedal tare da ƙarfin da ake so ba. An samar da tsarin taimakon birki na gaggawa, wanda aka gina na'urar firikwensin a cikin tsarin VUT. Yana auna saurin motsi na sandar, kuma da zarar darajarsa ta wuce ƙimar kofa, an kunna ƙarin solenoid, yana ɗaukar cikakken damar iyawar membrane, buɗe bawul ɗin sarrafawa zuwa matsakaicin.
