1. A signal acquisition sensor array, comprising: a connection layer, at least two types of sensor units, a signal acquisition circuit, and a signal line electrically connecting the sensor units with the signal acquisition circuit, wherein each of the at least two types of sensor units comprises:
a first vibration-proof substrate; and
a sensor element in one-to-one correspondence with the first vibration-proof substrate, is the sensor element disposed between the first vibration-proof substrate and the connection layer;
wherein the at least two types of sensor units are arranged in an array at intervals on the connection layer;
wherein a product of a vibration-proof property of the first vibration-proof substrate of one sensor unit, a sensitivity of the sensor element of the one sensor unit and a sensitivity of the corresponding signal acquisition circuit is twice or more times of a product of a vibration-proof property of the first vibration-proof substrate of another sensor unit, a sensitivity of the sensor element of the other sensor unit and a sensitivity of the corresponding signal acquisition circuit.
