Abstract

The invention relates to the technical field of transduction devices, in particular to an ultrasonic transduction device. The ultrasonic transduction device comprises a shell and a transduction module arranged in the shell. The transduction module comprises a plurality of transduction parts connected in series and distributed coaxially in sequence. Each transduction part comprises a piezoelectric ceramic ring, an outer conducting layer and an inner conducting layer, wherein the outer conducting layer is attached to an outer silver layer of the piezoelectric ceramic ring, and the inner conducting layer is attached to an inner silver layer of the piezoelectric ceramic ring. On the condition that the conducting performance of the transduction parts is not affected, direct welding on the silver layers is avoided, so that the problems, caused by welding or vibration, that the silver layers fall off and the piezoelectric ceramic ring is uneven in vibration and prone to cracking are avoided. The ultrasonic transduction device is stable in power, and the service life of the ultrasonic transduction device is prolonged.

Description

technical field [0001] The invention relates to the technical field of transducers, in particular to an ultrasonic transducer. Background technique [0002] At present, the inside and outside of the piezoelectric ceramic ring in the transducer device on the market are provided with silver layers, which are respectively used as the positive and negative electrodes of the piezoelectric ceramic ring, and the positive and positive electrodes, negative and negative electrodes of the piezoelectric ceramic ring are all welded by welding wire. , It is easy to cause the silver layer to fall off, which not only reduces the power, but also causes the piezoelectric ceramic ring to vibrate unevenly, causing the piezoelectric ceramic ring to crack during the vibration process and affecting the overall life of the transducer device. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to solve the ...
