A shockwave probe transducer structure includes a shock cup, a magnetic disc and a focusing module. The focusing module includes a circular cover and a focusing member installed between the circular cover and the shock cup. The focusing member is consisted of a focusing bag or a lens and a focusing bag closely coupled to each other. The focal point of the shockwave of the shockwave probe transducer structure can be changed by simply changing the focusing module installed at the front of the shockwave probe transducer structure, so as to overcome the problems of complicated changing procedure and possible water leakage and avoid the risk of damaging an expensive shockwave system or jeopardizing the safety of people.
