Abstract
The utility model relates to an electronic stethophone having contacting type microphone, which is provided with a stethophone head connected with a micro-control unit (MCU) by an electric line. The micro-control unit is connected with a prefix OP amplifying circuit, a filter circuit and a transmitting circuit. In using, the stethophone head conveys the weak sound signal generated by attaching human body to the prefix OP amplifying circuit for amplifying, then the micro-control unit makes the sound signal for measurement (heart sound or lung sound) chosen by a switch module to be treated by the electric filter in the filter circuit and delivers the treated sound signal to an emitting/receiving circuit. Thus, under the control of the micro-control unit, the sound generated by human body can be purified by the filter circuit, only leaving the accurate sound signal to be delivered to the medical staff by the emitting/ receiving circuit for making correct diagnosis.
