The invention discloses an
electronic stethoscope based on an n-type
cantilever beam type one-dimensional MEMS
acoustic sensor, and belongs to the technical field of biomedical devices. The
electronic stethoscope comprises a supporting threaded connector, a heart sound probe shell and an MEMS
acoustic sensor microstructure, wherein the supporting threaded connector is composed of a triangular supporting frame, a supporting column, a fastening bolt, a sliding block, a connecting rod, a supporting plate and a supporting rod, the heart sound probe shell is composed of an oval shell, a cover body and an induction film, and the MEMS
acoustic sensor microstructure is arranged in the heart sound probe shell. The
electronic stethoscope is scientific in design, reasonable in structure, small in size, attractive, low in cost, easy to
machine, easy to produce in batches, convenient and stable to use and operate, high in detection sensitivity, high in anti-jamming capability, high in
signal-to-
noise ratio, high in reliability, high in bandwidth, good in detection effect and worthy of popularization and application.
