The invention relates to the technical field of extracting and processing biomedical information, in particular to a combined type multi-output body surface gastric stimulation device and a using method thereof. The device comprises a data storage module (101), an AV (Audio/Video) decoder module (102), an electrogastrogram signal preprocessing module (103), a signal modulating and processing module (104), an electrode output module (105) and an audio output module (106). According to the invention, an audio signal is utilized for modulating an electrogastrogram signal, the modulated electrogastrogram signal is used to act on a human body, the audio signal is used to simultaneously and directly act on the human body, the audio signal obtained by hearing and the electrogastrogram signal sensed by touch sensation both carry audio information, the information sensed by the human body is combined type multi-output information, a patient not only obtains audio stimulation by hearing, but also perceives the audio information simultaneously by touching sensation, and thus a better therapy effect can be produced.
