迷你按(an)(an)摩(mo)器分電磁式按(an)(an)摩(mo)器和(he)電動(dong)按(an)(an)摩(mo)器，二者的(de)原理不(bu)同。

電(dian)(dian)磁式按摩器主要由(you)電(dian)(dian)磁線芯和線圈組(zu)成，當(dang)線圈通以50Hz的工(gong)頻(pin)交流電(dian)(dian)時即產生交變磁場，交變磁場忽小(xiao)忽大，帶(dai)動(dong)鐵芯產生振動(dong)，再把(ba)振動(dong)傳到按摩頭(tou)上，由(you)于我國使用50Hz交流電(dian)(dian)，故按摩頭(tou)的振動(dong)頻(pin)率為(wei)100Hz。

電(dian)動(dong)(dong)(dong)(dong)(dong)式按摩(mo)器(qi)的振動(dong)(dong)(dong)(dong)(dong)源是(shi)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，一般來(lai)說，按摩(mo)器(qi)的電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)為(wei)永磁(ci)式微型直流電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)。電(dian)動(dong)(dong)(dong)(dong)(dong)按摩(mo)器(qi)的工作(zuo)原理為(wei)：電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)主軸(zhou)的轉動(dong)(dong)(dong)(dong)(dong)通過聯(lian)軸(zhou)彈簧傳(chuan)到偏(pian)心輪(lun)(lun)上，偏(pian)心輪(lun)(lun)的作(zuo)用是(shi)把電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的旋(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(chuan)給振動(dong)(dong)(dong)(dong)(dong)頭(tou)，由(you)于(yu)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)轉速為(wei)5000～10000轉/分，故電(dian)動(dong)(dong)(dong)(dong)(dong)式按摩(mo)器(qi)的振動(dong)(dong)(dong)(dong)(dong)次數亦為(wei)每(mei)分鐘5000～10000次。
