1.High Efficiency: of high mechanical factor. High transfer efficiency is obtained when working in resonance frequency.
2.Big amplitude: designed and chosen by computer, high oscillation speed and big amplitude in front operculum.
3.Big Power: under the function of the prestressed force screw rod, the piezoelectricity ceramics can work freely in the highest level of power.
4.In good heat resistance: of small resonance impedance, less heat produced, can be used in a wide range of temperature with long life and
