A mobile device for an electronic stethoscope, including: a microphone, which receive an acoustic signal coming from an area of the body during a detection period and generates an auscultation signal of an electrical type, as a function of the acoustic signal a transmitter a processing unit, which transmits the auscultation signal to an external electronic device, through the transmitter and an electronic accelerometer, which generates an acceleration signal indicating acceleration of the mobile device. The processing unit generates, on the basis of the acceleration signal, a position signal, indicating the position of the mobile device during the detection period, and transmits the position signal to the external electronic device, through the transmitter.
