The invention belongs to the design of sensors, particularly relates to a design method of an acoustic sensor and puts forward a design scheme of the acoustic sensor by imitating the ultra structure of an orthoptera singing insect patagium for overcoming the defects that traditional acoustic sensors are complicated and not favorable for sensor miniaturization. In the technical scheme, a Q value is determined through the design of a fine structure on an acoustic sensor sensitive element surface to enable part of the structure of the sensor becomes redundant. Therefore, the Q value of the sensor can be enhanced to increase the sensor sensitivity and can also be reduced to widen the corresponding bandwidth of the sensor; particularly for a broadband sensor, the traditional damping structure in the acoustic sensor can be eliminated to greatly reduce the size of the sensor.
