Patent abstract

The invention disclosed that the multiple frequency ultrasound apparatus using unique transducer will contain many actuations module, a coupled circuit and a transducer. Each actuation module can separately output the signal of the different frequency, the coupled circuit connecting the actuation module for coupling with the signal of the different frequency. The transducer can receive the signal of the multiple frequencies, then for outputting the multiple ultrasound frequency by the way of transferring from the electrical energy to the mechanical energy.
