The invention discloses a method for preparing a multilayer piezoelectric film, a piezoelectric module and electronic equipment. The method for preparing the multilayer piezoelectric film comprises the step of sequentially preparing electrode layers and piezoelectric film layers which are alternately arranged on a substrate so as to obtain the multilayer piezoelectric film. The step of preparing the nth piezoelectric film layer comprises the steps that: in a crystallization auxiliary solvent atmosphere, the nth piezoelectric film layer is crystallized through heat treatment, so that crystal particles of the nth piezoelectric film layer penetrate through part of the electrode layer to be connected with the (n-1) th piezoelectric film layer, wherein n is larger than or equal to 2. According to the method for preparing the multi-layer piezoelectric film, the piezoelectric module and the electronic equipment, when the multilayer piezoelectric film is prepared, the piezoelectric film layers do not need to be attached through glue, so that the overall thickness of the piezoelectric module can be reduced, and the performance of the piezoelectric module is improved.
