迷(mi)你按摩器分電(dian)磁(ci)式按摩器和電(dian)動按摩器，二者的原(yuan)理不同。

電(dian)(dian)(dian)磁式按(an)摩器(qi)主要由電(dian)(dian)(dian)磁線(xian)(xian)芯(xin)(xin)和線(xian)(xian)圈(quan)組成，當(dang)線(xian)(xian)圈(quan)通以50Hz的工(gong)頻交(jiao)(jiao)流(liu)電(dian)(dian)(dian)時即產生(sheng)交(jiao)(jiao)變磁場(chang)，交(jiao)(jiao)變磁場(chang)忽(hu)小忽(hu)大，帶動(dong)鐵芯(xin)(xin)產生(sheng)振(zhen)動(dong)，再把振(zhen)動(dong)傳到按(an)摩頭上，由于我國使用50Hz交(jiao)(jiao)流(liu)電(dian)(dian)(dian)，故按(an)摩頭的振(zhen)動(dong)頻率為100Hz。

電(dian)動(dong)(dong)(dong)(dong)(dong)式按(an)摩器的(de)(de)振動(dong)(dong)(dong)(dong)(dong)源(yuan)是電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)，一般(ban)來(lai)說(shuo)，按(an)摩器的(de)(de)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)為(wei)永磁式微型直流電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)。電(dian)動(dong)(dong)(dong)(dong)(dong)按(an)摩器的(de)(de)工作原(yuan)理(li)為(wei)：電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)主軸的(de)(de)轉動(dong)(dong)(dong)(dong)(dong)通過(guo)聯(lian)軸彈簧傳到偏(pian)心輪上，偏(pian)心輪的(de)(de)作用(yong)是把電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)旋(xuan)轉運(yun)動(dong)(dong)(dong)(dong)(dong)轉化為(wei)往復運(yun)動(dong)(dong)(dong)(dong)(dong)，并把往復運(yun)動(dong)(dong)(dong)(dong)(dong)傳給振動(dong)(dong)(dong)(dong)(dong)頭，由于電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)轉速(su)為(wei)5000～10000轉/分，故(gu)電(dian)動(dong)(dong)(dong)(dong)(dong)式按(an)摩器的(de)(de)振動(dong)(dong)(dong)(dong)(dong)次(ci)數亦為(wei)每(mei)分鐘5000～10000次(ci)。
