•  High efficiency: high mechanical parameter Q, the transduction efficient between electricity and sound above 95%.

• High amplitude: the transducer strength is improved by fixing the high speed vibrator directly on the base of washing groove with bolt. Compare with a magnetic expansion vibrator, its amplitude can be improved above 50%.

• Good heat resistance: a large range of working temperature, low resonance impedance and heat productivity.

• Good construction: fastened by bolt, easy for assembling, high reliability.
