The invention discloses a voiceprint monitoring device with a self-powered sensor for an electric aircraft, which is used for monitoring voiceprint parameters of the electric aircraft and comprises a sensor, a voiceprint monitor and a control center, the sensor is fixedly mounted on a fuselage of the electric aircraft to receive voiceprint information generated by the electric aircraft and convert the voiceprint information into an electric signal, and the voiceprint monitor receives the electric signal sent by the sensor and performs A/D conversion to generate a data packet; the voiceprint monitor sends the data packet to a control center in a wireless or optical fiber communication mode, the sensor comprises a suction cup cover, a barrel and a bottom cover, the suction cup cover and the bottom cover are fixed to the two ends of the barrel respectively, a substrate, a vibrating diaphragm and a microphone chip are arranged on the upper side of the suction cup cover, and the bottom cover is fixed to the bottom cover. The microphone chip is installed on the substrate and generates a detection signal through airflow change generated by vibration of the vibrating diaphragm, and the electromagnetic power generation assembly and the piezoelectric power generation assembly in the barrel can provide electric energy for the substrate.
