| titleOfInvention | Magnetic induction type electronic stethoscope probe based on MEMS technology |
| abstract | The invention relates to a magnetic induction type electronic stethoscope probe based on an MEMS (micro-electromechanical systems) technology, which solves the problem that the sensitivity and the signal-to-noise ratio of the existing heart sound sensor are mutually restricted. The electronic stethoscope probe comprises a negative pressure bag, a heart sound probe shell, a connecting body, a chip packaging shell, an MEMS (micro-electromechanical systems) acoustic sensor microstructure and an induction film which are sequentially nested together in a mortise-tenon manner, wherein a magnet is arranged on the induction film. The electronic stethoscope probe disclosed by the invention can convert and separate the heart sound signal from the external environment vibration noise, so as to carry out specificity detection, reduce the influence of the environment noise on the detection of the heart sound signal, improve the anti-interference capability of the electronic stethoscope probe and improve the accuracy of the heart sound detection. Meanwhile, because the heart sound signals acquired by the sensor are original signals, the difficulty of a rear-end signal processing circuit and a noise elimination algorithm is reduced. |
