description	A piezoelectric vibrator has a vibration generator connected via a phase difference device to two sets of linear transducers One transducer set couples a relay plate to a base plate and the other transducer set couples the relay plate to an inertial mass. An Independent claim is included for the following: (a) Seismic surveying using vibrator(s) as above coupled to a central station so that each vibrator receives an elastic wave transmitted through a rock formation Preferred Features: The vibrator has a secon relay plate and four sets of transducers coupling the base plate to the inertial mass via the two relay plates. The transducers only attached to one side of the relay plate. The transducer sets are excited with signals or different phase and/or amplitude i order to equalize the frequency response of the vibrator.
