PURPOSE: A wireless electron stethoscope using Bluetooth communication is provided to prevent a sound loss in a patient diagnosis process by using wireless communication instead of a rubber tube. CONSTITUTION: A stethoscope body is comprised of a thin film plate. A microphone(61) collects the sound of the thin film plate. A sound collected by the microphone is converted into a fine electric signal. A noise filter(62) removes the white noise of an electric signal. A frequency filter amplifies an electric signal. A Bluetooth transceiver module(70) transmits the amplified electric signal by wireless.
