Compare with prior art, the utlity model has following advantage:

1. stimulus modality can be selected on demand, and existing steady job pattern has the setting mode of operation again.

2. the frequency of sound wave, the suffered sound intensity of object can show in real time, and is easy to adjust; Utilize the keyboard to set up working time, easy and simple to handle.

3. if use the steady job pattern, need not keep the marquis by manpower always, thereby save manpower.

4. can separate with extraneous sound field preferably, disturb less.

5. can not only handle plant seed, also can stimulate, thereby be more suitable in middle-size and small-size farm and Nong Ke department to plant or plant tissue.

6. the uniform rotation because of electromotor makes the suffered sound stimulation of irriate object even relatively, and effect is better.

7. circuit adopts chip more, and is easy to maintenance, and cost is not high.
