An ultrasonic cleaning transducer is a device that converts high frequency electrical energy into mechanical energy. The electrical signal is converted to mechanical vibration by the piezoelectric effect of the material. An ultrasonic transducer is an energy conversion device whose function is to convert the input electrical power into mechanical power (ie, ultrasonic waves) and then pass it out, while consuming a small portion of the power itself. It has a certain frequency characteristic, so it is necessary to consider factors such as power, impedance matching, and frequency when designing its driving.

ultrasonic transducer for ultrasonic bath devices that convert electrical energy into mechanical energy and are relatively expensive. The circuit can refer to the ultrasonic humidifier circuit. Pay attention to the research direction, even if the signal stability of the drive circuit can not change the problem of low power, the thing that the electrical energy is converted into mechanical energy is mainly the current of the oscillating circuit. This is like a quartz crystal oscillator, which has a strong response to a fixed frequency.
