A vibratory anti-noise electronic stethoscope comprises an auscultatory head, a resonant cavity, a three-way catheter and an earplug catheter, wherein the auscultatory head comprises a shell and a vibration sensor; the vibration sensor is connected with an amplification circuit; the amplification circuit is connected with a loudspeaker; the loudspeaker is arranged inside the resonant cavity; the resonant cavity is arranged inside a barrel body; the barrel body is connected with an upper cover; a three-way catheter faucet is formed inside the upper cover; and the three-way catheter faucet is connected with the three-way catheter. The vibratory anti-noise electronic stethoscope replaces the auscultatory body of the conventional stethoscope with the electronic vibration sensor, directly converts vibration of an auscultatory part into an electrical signal, amplifies the electrical signal by the amplification circuit, outputs the electrical signal to the loudspeaker, arranges the loudspeaker inside the resonant cavity and transmits sound to two ears of medical personnel through the three-way catheter and the earplug catheter in the conventional stethoscope, so that outside sound can be completely shielded, the using way meets the traditional auscultatory habits, noises can be eliminated in the power amplifying process, and auscultatory sound is pure without interfering sound and background noise.
