The invention relates to a low-frequency infrasound physiotherapy device, which comprises: a host and a infrasound pusher, the host has a generation unit of the infrasound frequency, which can generate one or more infrasound frequency frequency signals; the infrasound pusher is electrically connected with the host, and receives the frequency signals transmitted by the host to send out the infrasound frequency signals. With the wave kinetic energy of the low-frequency infrasound wave, the physiotherapy device can provide the function of relieving and adjusting the human body, and can provide the penetration function of shallow layer and depth to the human body.本創作係關於一種低頻次聲波理療器,包含有:一主機及一次聲波推動器,該主機具有一次聲波頻率產生單元,可產生一個或一個以上的次聲波頻率的頻率訊號;該次聲波推動器係與該主機電性連接,並接收該主機所傳送之頻率訊號,以發出該頻率之次聲波。藉由該低頻次聲波之波動能,該理療器可對人體提供舒緩與調節功能,可對人體提供淺層與深度的透導作用。
