Abstract: The present application provides a power generator, a suspension, a vehicle, an apparatus and a method for producing a power generator. Among them, the power generator comprises a cylinder body, a moving member, and a piezoelectric conversion unit. The moving member and the cylinder body jointly defines a variable cavity. The piezoelectric conversion unit is located in the variable cavity, and the piezoelectric conversion unit is configured to deform when the moving member is in relative motion with respect to the cylinder body move and changes the size of the variable cavity, for generating electric energy. Due to the fact that the piezoelectric conversion unit is arranged in the variable cavity, the moving member is in relative motion with respect to the cylinder body to make the piezoelectric conversion unit generate electric energy, thus effectively utilizing the energy generated by the target members in the vibration process.
