迷(mi)你按(an)摩器分電(dian)磁式按(an)摩器和電(dian)動按(an)摩器，二者(zhe)的原(yuan)理(li)不(bu)同。

電磁式(shi)按摩器(qi)主(zhu)要由電磁線芯和(he)線圈(quan)組成，當線圈(quan)通以50Hz的(de)工頻交流電時即產生交變磁場，交變磁場忽小忽大，帶動(dong)鐵芯產生振動(dong)，再把振動(dong)傳到(dao)按摩頭(tou)上，由于(yu)我國使(shi)用50Hz交流電，故按摩頭(tou)的(de)振動(dong)頻率為100Hz。

電(dian)(dian)(dian)(dian)動(dong)式(shi)按(an)摩(mo)器的(de)振動(dong)源是電(dian)(dian)(dian)(dian)動(dong)機(ji)，一般(ban)來說，按(an)摩(mo)器的(de)電(dian)(dian)(dian)(dian)動(dong)機(ji)為(wei)永磁(ci)式(shi)微型直流電(dian)(dian)(dian)(dian)動(dong)機(ji)。電(dian)(dian)(dian)(dian)動(dong)按(an)摩(mo)器的(de)工(gong)作(zuo)原理為(wei)：電(dian)(dian)(dian)(dian)動(dong)機(ji)主軸的(de)轉(zhuan)動(dong)通過(guo)聯軸彈簧傳(chuan)(chuan)到偏心輪(lun)上(shang)，偏心輪(lun)的(de)作(zuo)用是把電(dian)(dian)(dian)(dian)動(dong)機(ji)的(de)旋(xuan)轉(zhuan)運動(dong)轉(zhuan)化為(wei)往復運動(dong)，并把往復運動(dong)傳(chuan)(chuan)給振動(dong)頭，由于電(dian)(dian)(dian)(dian)動(dong)機(ji)轉(zhuan)速為(wei)5000～10000轉(zhuan)/分，故電(dian)(dian)(dian)(dian)動(dong)式(shi)按(an)摩(mo)器的(de)振動(dong)次數亦為(wei)每(mei)分鐘(zhong)5000～10000次。
