In this paper, according to the electromagnetic relation needed the electric vibrator while realizing the large amplitude in the electromechanical resonance state, the structural parameters of the experimental prototype are analyzed in detail, the objective function based on the minimum producing-and-running cost is constructed, then the optimization design of the structural parameters and the operation parameters of this electric vibrator in the resonance state is finished by MATLAB, and finally its optimal structural parameters are decided while it produces＇ the larger amplitude with the smaller electromagnetic force. This presents＇ an effective method of the mechanical structural design of the electromagnetic vibrator in the electromechanical resonance state.
