Through dynamic impedance matching by kernal control circuit based on C8051F020 and AD9832, the maximum output of ultrasound power is produced.

方法：基于C8051F 020和AD 9832的核心控制电路通过动态阻抗匹配法使系统输出最大超声波功率。

This changing "reactive" load causes the amp output level to change with frequency and changes in speaker impedance (a dynamic thing that changes as the speakers are driven harder).

这种变化的“反应”负荷导致功放输出水平的变化与频率变化，音箱阻抗（动态改变的内容作为扬声器驱动更难） 。
