The invention discloses a macro-micro combination continuously variable transmission of an electromagnet-ultrasonic transducer and a method of the macro-micro combination continuously variable transmission, belonging to the field of transmissions. The macro-micro combination continuously variable transmission comprises a box body (8) which is provided with a front end cover (10) and a rear end cover (3); and the macro-micro combination continuously variable transmission further comprises an input shaft component arranged on the front part of the box body and an output shaft component arranged on the rear part of the box body. According to the device, continuously variable transmission is realized by combining macro control and micro control; the reduction gear is small in size, simple in structure and easy for machining, assembling and using; speed change is continuous and adjustable; response time is short; and control is easy.
