Current vibrator has some problems suah as heavy mass

large volume

poor signal repeatability

low precision and complicated operation

and can not be widely applied to complex zone microseismic monitoring.Aiming at these problems

a design method of lightweight small piezoelectric ceramic seismic source is proposed.Researches are carried out from the perspectives of material selection

working principle and structure design. Field tests show that the developed compact and small piezoelectric ceramic seismic source has advantages of small

light

stable output signal

repeatable and easy to operate

and it is suitable for microseismic monitoring of complex terrain.
