A digital seismograph with a plurality of transducers pertains to the field of earthquake measuring instrument. The utility model comprises three diffluent energy vibration units with three dimensions and the transducers of each diffluent energy vibration units; a maximum of three types of the transducers are available synchronously, including two dynamic transducers, a capacitance transducer and a photoelectric transducer. The utility model is characterized in that the two dynamic transducers and the capacitance transducer are arranged on a same axle core line; the photoelectric transducer with optical lever amplification is arranged paralleling to the axle core line; each transducer is connected to an AD analog-digital convertor and each transducer of each diffluent energy outputs through a digital vibration signal. The digital seismograph with a plurality of transducers is capable of measuring weak earthquake far away, enhances the instrument sensitiveness, realizes to integrate three instruments in one and provides effective functions to earthquake monitoring and forecast research.
