Langevin Ultrasonic Piezoelectric Cleaning Transducer With 40KHz 28KHz Ultrasonic Transducer

The acoustic transducer has sharp directionality, which is conducive to concentrating the emitted energy, achieving a high signal-to-noise ratio when received, and also facilitating the positioning and evaluation of the detected target. The manufacturer of Ultrasonic welding machine indicates that the ultrasonic transducer is related to its radiation surface size, structure, operating frequency and sound transmission medium characteristics. Most of them can use directivity factors to reflect the directivity of the ultrasonic transducer.

Ultrasonic transducer

The so-called directivity factor refers to the ratio of the mean square sound pressure of a certain frequency at a certain point away from the emitting ultrasonic transducer on the sound pressure of the main axis of the emitting sound beam to the mean square sound pressure of the same frequency at a certain point on the spherical surface concentric with the transducer passing through the point. For receiving ultrasonic transducers, the horn manufacturer states the ratio of the square value of the electromotive force generated by a certain frequency of sound waves transmitted along the main axis of the transducer to the square value of the electromotive force generated by a diffusion sound field with the same frequency and root mean square sound pressure.
