迷你(ni)按摩器(qi)分電(dian)磁式按摩器(qi)和(he)電(dian)動按摩器(qi)，二(er)者的原理不同。

電磁式按(an)摩(mo)器主要由電磁線芯和線圈組成，當線圈通以50Hz的(de)工頻(pin)交流電時即(ji)產生交變磁場，交變磁場忽小忽大，帶動(dong)(dong)鐵芯產生振動(dong)(dong)，再(zai)把(ba)振動(dong)(dong)傳(chuan)到按(an)摩(mo)頭(tou)上(shang)，由于我國使(shi)用50Hz交流電，故按(an)摩(mo)頭(tou)的(de)振動(dong)(dong)頻(pin)率為100Hz。

電(dian)動(dong)(dong)(dong)式按(an)摩器的振(zhen)動(dong)(dong)(dong)源是(shi)電(dian)動(dong)(dong)(dong)機(ji)，一般來說，按(an)摩器的電(dian)動(dong)(dong)(dong)機(ji)為(wei)(wei)永(yong)磁式微型(xing)直流電(dian)動(dong)(dong)(dong)機(ji)。電(dian)動(dong)(dong)(dong)按(an)摩器的工作原(yuan)理為(wei)(wei)：電(dian)動(dong)(dong)(dong)機(ji)主軸(zhou)的轉(zhuan)(zhuan)動(dong)(dong)(dong)通過聯(lian)軸(zhou)彈簧傳(chuan)到偏心(xin)輪上，偏心(xin)輪的作用是(shi)把(ba)電(dian)動(dong)(dong)(dong)機(ji)的旋轉(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)轉(zhuan)(zhuan)化為(wei)(wei)往(wang)復運(yun)動(dong)(dong)(dong)，并把(ba)往(wang)復運(yun)動(dong)(dong)(dong)傳(chuan)給振(zhen)動(dong)(dong)(dong)頭，由于電(dian)動(dong)(dong)(dong)機(ji)轉(zhuan)(zhuan)速為(wei)(wei)5000～10000轉(zhuan)(zhuan)/分(fen)，故電(dian)動(dong)(dong)(dong)式按(an)摩器的振(zhen)動(dong)(dong)(dong)次(ci)(ci)數亦為(wei)(wei)每分(fen)鐘(zhong)5000～10000次(ci)(ci)。
