High Power 35Khz Ultrasonic Welding Transducer 

What is ultrasonic transducer?

    Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. When the transducer is used as a transmitter, the electrical oscillating signal sent from the excitation source will cause a change in the electric or magnetic field in the electrical energy storage element of the transducer, which changes the mechanical vibration system of the transducer through some effort. A driving force is generated to cause it to vibrate, thereby propelling themedium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium.

What's the relationship bewteen Frequencies and Amplitudes?

When an AC voltage is applied, piezo elements begin to oscillate. The extremely fast response in the microsecond range and below allow for ultrasound generation with frequencies of up to 20 MHz.

Ultrasonic applications can be classified in sensor applications and power ultrasound where the energy densities are higher and frequencies range from 20 to 800 kHz.

Power ultrasound can be used in medical applications, e.g. to crush kidney stones and for removing dental plaque, and industrial processes, such as cleaning and welding or bonding.

 The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expａnd and contract, producing axial vibrations.
