Patent ID: 6944496

Claim:
An apparatus for positioning and marking a location of an electromyography (EMG) electrode to convert an EMG signal to an audio EMG signal, comprising: a housing having a back surface; an EMG sensor, installed on the back surface of the housing, for receiving the EMG signal, wherein the EMG sensor has a sensing surface capable of being contacted with a human body; an amplifying circuit for amplifying the EMG signal to generate an amplified EMG signal; an audio output terminal, installed on a side of the housing, for outputting the amplified EMG signal as the audio EMG signal, wherein the audio output terminal has a structure capable of being connected with an audio input terminal of a audio device; a marking lever installed to be capable of moving along a lever guide conduit installed through the housing; and a marking tap, integratedly installed on an end of the marking lever, capable of being projected outside of the housing due to the movement of the marking lever.
