迷(mi)你按摩(mo)器(qi)分(fen)電磁(ci)式按摩(mo)器(qi)和電動按摩(mo)器(qi)，二者的原理不同。

電磁(ci)式(shi)按摩(mo)器主(zhu)要由(you)電磁(ci)線(xian)芯(xin)和(he)線(xian)圈組成，當線(xian)圈通以50Hz的工(gong)頻(pin)交(jiao)流電時即產生交(jiao)變磁(ci)場(chang)，交(jiao)變磁(ci)場(chang)忽小(xiao)忽大，帶動鐵芯(xin)產生振(zhen)動，再把振(zhen)動傳到按摩(mo)頭上(shang)，由(you)于我(wo)國使用(yong)50Hz交(jiao)流電，故按摩(mo)頭的振(zhen)動頻(pin)率為100Hz。

電(dian)動(dong)(dong)(dong)式按摩(mo)(mo)器的(de)(de)(de)(de)(de)振動(dong)(dong)(dong)源是(shi)電(dian)動(dong)(dong)(dong)機，一般來(lai)說，按摩(mo)(mo)器的(de)(de)(de)(de)(de)電(dian)動(dong)(dong)(dong)機為(wei)(wei)永磁(ci)式微型直流(liu)電(dian)動(dong)(dong)(dong)機。電(dian)動(dong)(dong)(dong)按摩(mo)(mo)器的(de)(de)(de)(de)(de)工作原理為(wei)(wei)：電(dian)動(dong)(dong)(dong)機主軸的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)動(dong)(dong)(dong)通(tong)過聯軸彈(dan)簧傳到偏(pian)(pian)心輪(lun)上，偏(pian)(pian)心輪(lun)的(de)(de)(de)(de)(de)作用是(shi)把電(dian)動(dong)(dong)(dong)機的(de)(de)(de)(de)(de)旋轉(zhuan)(zhuan)運動(dong)(dong)(dong)轉(zhuan)(zhuan)化為(wei)(wei)往復(fu)運動(dong)(dong)(dong)，并(bing)把往復(fu)運動(dong)(dong)(dong)傳給振動(dong)(dong)(dong)頭，由于(yu)電(dian)動(dong)(dong)(dong)機轉(zhuan)(zhuan)速(su)為(wei)(wei)5000～10000轉(zhuan)(zhuan)/分(fen)，故電(dian)動(dong)(dong)(dong)式按摩(mo)(mo)器的(de)(de)(de)(de)(de)振動(dong)(dong)(dong)次數亦為(wei)(wei)每分(fen)鐘5000～10000次。
