A control method for low-frequency device by using a computer system includes the following steps. A low frequency control software is installed into a computer system. A low frequency device is separated from the computer system. The low frequency device includes a low frequency pulse generating module for generating low frequency pulse being transmitted to a positive electrode and a negative electrode, wherein the positive electrode and the negative electrode are separated from each other. The computer system is electrically connected to the low frequency device for providing power and signals to the low frequency device. The operator controls the low frequency device to generate voltage and frequency of the low frequency pulse by using a low frequency pulse display-control unit that is shown on a display-control interface of the computer system due to the low frequency control software.一種利用電腦系統控制低週波裝置的方法及其裝置,所述方法主要包括:於一電腦系統中執行一低週波控制軟體;設製一低週波裝置獨立於電腦系統之外,低週波裝置包括低週波脈沖產生模組以產生低週波脈沖並傳輸到呈間隔配置的正、負電極;低週波裝置與電腦系統電性連接以藉由電腦系統提供電力與控制訊號給予低週波裝置;藉由低週波控制軟體於電腦系統的顯示控制介面中產生低週波脈沖顯示控制單元,以供使用者操控執行該低週波裝置產生低週波脈沖之電壓與頻率。10‧‧‧電腦系統11‧‧‧顯示控制介面12‧‧‧低週波脈沖顯示控制單元20‧‧‧低週波控制軟體30‧‧‧低週波裝置31‧‧‧低週波脈沖產生模組41‧‧‧正電極42‧‧‧負電極50‧‧‧耳機介面60‧‧‧裝置功能操作部
