The mechanical vibrator excited electrostrictively by BaTiO_3 Ceramic has been used as a resonator of the electro-mechanical filter for exciting and picking up, and as a simple source of sub-standard of frequency, and an electro-mechanical transducer.　In this paper, some examples of the fundamental construction of these electro-mechanical vibrators and theoretically analized. For analysis, the equivalent circuit of these vibrators has been derived and solved by the method of electro-mechanical analogy.　The electrostrictive materials (for example, BaTiO_3 Ceramic) pasted rigidly to the base vibrator (for example, steel bar) which operate as an additional impedance load change the frequency and sharpness of the apparent resonance.　It is important, therefore, for the design and improvement of the vibrator that these vibrators should be synthetically discussed from the view point of electro-mechanical system.
