Searching 20Khz 2000w Ultrasonic Transducer for Mask Non Woven Welding with Black Ceramics

Description:

The ultrasonic transducer converts the electrical or magnetic energy output by the ultrasonic generator into mechanical vibration of the same frequency. At present, the piezoelectric ceramic transducer is used on the mask machine. The piezoelectric effect of the material converts electrical signals into mechanical vibrations. The working principle of medical ultrasound transducers (ultrasound probes) is basically the same, and its interior usually contains an electrical energy storage element and a mechanical vibration system. When the transducer is used as a transmitter, the electric oscillation signal sent from the excitation power supply will cause the electric field or magnetic field in the electric energy storage element of the transducer to change. This change will affect the mechanical vibration system of the transducer through some effect. A driving force is generated to enter the vibration state, thereby driving the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium. The process of receiving sound waves is just the opposite. The external sound waves act on the vibrating surface of the transducer, thereby causing the mechanical vibration system of the transducer to vibrate. With a certain physical effect, it causes the electric field or the energy storage element of the transducer. The magnetic field changes accordingly, causing the electrical output of the transducer to generate a voltage and current corresponding to the acoustic signal.
