Abstract
Звуковая система мультимедиа с цифровым интерфейсом звуковой частоты включает в себя не меньше одного интерфейса USB или интерфейса IEEE1394, одной внешней звуковой карты USB или IEEE1394, одной группы усилителя сорта D или сорта Т и согласованного контрольной электрической цепи или чип микропроцессора, одной плиты РСВ и не меньше одной пары звуковой колонки с характеристикой нагрузки сопротивления одной вибрационной плёнки или приближённой характеристики сопротивления и/или полосовой репродуктор сильного баса. В каждой колонке установится не меньше одного репродуктора многого магнитного промежутка, многой обмотки и ленты полной частоты, размер данного репродуктора не превышает 7 дюймов. Данный репродуктор, звуковой канал 2.0 или 2.1 по электроснабжению путём USB компьютера или интерфейса IEEE1394 и звуковой канал 4.1-7.1 по электроснабжению путём независимого электропитания входят в составы цифровой звуковой системы мультимедиа звуковой частоты.
