摘要：
A portable audio output apparatus, including an audio output module configured to be in contact with a user's body and to output an audio signal, and a body fat sensor configured to sense a body resistance value of the user through at least four body contact nodes, is provided. At least two of the nodes are placed at outer surface areas of the audio output apparatus that are out of contact with the body if the user wears the audio output apparatus.
