Abstract

The invention discloses an ultrasonic transducer. The ultrasonic transducer comprises a first electrode component and a second electrode component; an insulating component, which is used for isolatingthe first electrode component from the second electrode component; a piezoelectric element, against which the second electrode component abuts; and a housing, which can compress the piezoelectric element, and is electrically conducted with the first electrode component and the piezoelectric element respectively. According to the ultrasonic transducer, the second electrode component abuts againstthe piezoelectric element, and the housing is electrically connected with the first electrode component and the piezoelectric element, so that a bonding wire is prevented from being used for conduction; and through match pressing of the second electrode component and the housing, the piezoelectric element can convert electric signals into mechanical vibration based on the piezoelectric effect under the power-on condition so as to achieve ultrasonic transduction. Due to the fact that no bonding wire is used, the problem that sound wave output is unstable due to the fact that the bonding wire isprone to falling off is solved, and the ultrasonic transducer has good application prospects in the technical field of ultrasonic treatment.

Description

technical field [0001] The invention relates to the technical field of transducers, in particular to an ultrasonic transducer. Background technique [0002] Ultrasound therapy technology is a non-invasive surgical technology that has been vigorously developed in recent years. Because it is non-invasive, harmless, safe, effective and can ensure the safety and integrity of tissues during the treatment process, it has been widely used in clinical medicine. application and promotion. Ultrasonic transducers are the core part of ultrasonic therapy and are widely used in treatment systems such as gynecological inflammation. Ultrasonic transducers are usually made of piezoelectric ceramics, which use the piezoelectric effect of piezoelectric ceramic materials to convert electrical signals into mechanical vibrations , the ultrasonic transducer in the prior art usually connects the electrodes to the piezoelectric ceramics in the form of welding wires. The welding points in the form o...
