Intelligent stethoscope

The invention discloses an intelligent stethoscope. The intelligent stethoscope comprises a handle end. The handle end internally comprises an audio converter, a DSP chip, an amplifier and a Bluetoothtransmitter which are sequentially connected. An analog-to-digital conversion module, an adjustable filtering frequency band module and an audio processing module are constructed on the DSP chip. Theinput end of the analog-to-digital conversion module is connected to the output end of the audio converter. The audio processing module selects a corresponding frequency band from the adjustable filtering frequency band module to filter the output of the analog-to-digital conversion module according to an external instruction and outputs the filtered output to the amplifier. According to the intelligent stethoscope, the DSP chip is used to replace an analog circuit and can compile audio signal data flow, the selectivity and signal-to-noise ratio of audio signals are further improved through techniques such as noise re
