首先(xian)，在使(shi)用效率(lv)方面，環(huan)(huan)型(xing)(xing)(xing)變(bian)(bian)(bian)壓器(qi)較高(gao)。其(qi)鐵芯是由不間斷的連續(xu)有(you)取向(xiang)硅(gui)鋼帶繞(rao)(rao)制而成，經過(guo)退(tui)火后會(hui)形(xing)成高(gao)度一致的磁通導向(xiang)，同(tong)(tong)時其(qi)繞(rao)(rao)組是緊(jin)密覆(fu)蓋(gai)著環(huan)(huan)形(xing)鐵芯進(jin)行繞(rao)(rao)制的，磁通密度較高(gao)。因(yin)此，環(huan)(huan)型(xing)(xing)(xing)變(bian)(bian)(bian)壓器(qi)可以(yi)達到很高(gao)的電(dian)氣效率(lv)。其(qi)次，音響(xiang)功放機在工作時常遇(yu)到有(you)電(dian)流聲(sheng)，或者有(you)“嗡(weng)嗡(weng)”聲(sheng)，而環(huan)(huan)型(xing)(xing)(xing)變(bian)(bian)(bian)壓器(qi)繞(rao)(rao)組均(jun)勻，銅(tong)線緊(jin)緊(jin)包(bao)住環(huan)(huan)形(xing)鐵心，有(you)效減小(xiao)了磁致伸縮引起的“嗡(weng)嗡(weng)”聲(sheng)。同(tong)(tong)時環(huan)(huan)型(xing)(xing)(xing)變(bian)(bian)(bian)壓器(qi)瞬時過(guo)載能(neng)力強(qiang)，能(neng)接(jie)受因(yin)低音時產生的大電(dian)流沖擊(ji)，響(xiang)應速度快(kuai)。另(ling)外，環(huan)(huan)型(xing)(xing)(xing)變(bian)(bian)(bian)壓器(qi)外形(xing)尺寸(cun)小(xiao)，容易安裝，只有(you)中(zhong)心一個安裝螺桿，特(te)別容易在電(dian)子設備(bei)中(zhong)進(jin)行快(kuai)速安裝與(yu)拆(chai)卸。
