摘要:
A Doppler ultrasonic pickup analyzing and processing method and device, the method comprising the following steps: transmitting an ultrasonic wave signal of a fixed frequency to a sound producing target such as human tissue or a resonance part both comprising vocal cords and vibrating with the vocal cords, and a non-living sound producing object, and receiving a reflected echo signal of the ultrasonic wave signal returned from the sound producing target (S101) amplifying the reflected echo signal, and comparing the amplified signal with the ultrasonic wave signal or a reference ultrasonic wave signal to obtain a Doppler frequency shift signal comprising the sound production feature of the sound producing target (S102) and outputting the Doppler frequency shift signal as an audio signal or a visible spectrogram for a corresponding application, or as a light signal (S103). The method, based on the Doppler ultrasonic principle, transmits an ultrasonic wave signal to a sound producing target, receives an echo signal for analysis and processing, extracts a Doppler frequency shift signal comprising the sound production feature of the sound producing target, and outputs the Doppler frequency shift signal as an audio signal, a visible spectrogram, or a light signal, thus overcoming the defects of an ordinary microphone and a bone conduction microphone.La présente invention concerne un procédé danalyse et de traitement par capteur ultrasonore à effet Doppler et un dispositif, le procédé comprenant les étapes suivantes : transmission dun signal donde ultrasonore dune fréquence fixe à une cible produisant un son comme un tissu humain ou une partie de résonance, les deux comprenant des cordes vocales et vibrant avec les cordes vocales, et un objet non vivant produisant un son, et la réception dun signal décho réfléchi du signal donde ultrasonore renvoyé de la cible produisant un son (S101) amplification du signal décho réfléchi, et comparaison du signal amplifié au signal donde
