Ultrasonic cleaning is widely applied in industry, yet it's still waiting for development in the field of washing machine(family type). The traditional electrostrictive transducer can't satisfy the washing requirements because of its limited strain, low density, single output frequency, and weak penetration. For a long time people have been dreaming about the ultrasonic washing machine turning into reality. And if it did come into true, the environment will be protected for the amount of cleaning agent or laundry powder will be noticeably reduced.

    The giant magnetostrictive transducer has the strain that is much higher than that of the electrostrictive or the traditional magnetostrictive transducer; it possesses qualities like high energy density, adjustable waveband and frequency, strong penetration, and significant washing effects. The high-powered, small-sized ultrasonic transducer makes the design more reasonable, and because of it's small size and light weight, it's very suitable for family use. At present, ultrasonic washing machine has alreaby appeared in the Japanese market. Evidently, it's becoming urgent for us to develop our own ultrasonic washing machine.

    Market Analysis
    Because of China's huge population, the need for washing machine is very large. The new magnetostrictive washing machine's unit price in Japan equivalents to about гд13,000. China is abundant of rare earth resources, material cost is much cheaper than other countries, moreover, it can be further reduced along with the increasing demand. If sales could reach up to 1 million, the profit can be around гд0.9 billion. Estimated as following:
