Abstract
Description
Technical Field
[0001] This utility model discloses an ultrasonic transducer, belonging to the field of transducer technology, specifically relating to a double-sided sound-emitting sheet-like ultrasonic transducer. Background Technology
[0002] The core function of an ultrasonic transducer is to achieve bidirectional conversion between electrical energy and mechanical energy (acoustic energy), and to achieve precise control of energy form through the piezoelectric effect. An ultrasonic transducer is a device that converts electromagnetic energy into mechanical energy (acoustic energy), and is usually made of piezoelectric ceramics or other magnetostrictive materials. Common applications of ultrasonic transducers include ultrasonic cleaners, ultrasonic atomizers, and B-mode ultrasound probes.
[0003] Existing ultrasonic transducers achieve energy conversion through electrode plates and piezoelectric ceramics. However, traditional ultrasonic transducers use a single-piece sound-generating structure, and energy is transferred in only one direction, resulting in energy waste. At the same time, the temperature of the ultrasonic transducer will increase, reducing the utility model life of the ultrasonic transducer. Utility Model Content

[0005] Technical solution: A double-sided sound-emitting sheet-shaped ultrasonic transducer, the ultrasonic transducer comprising: a piezoelectric ceramic sheet, a positive electrode sheet, a negative electrode sheet, a first insulating sheet, and a second insulating sheet;
[0006] The positive electrode and the negative electrode are respectively fixedly installed on the upper and lower surfaces of the piezoelectric ceramic sheet. The first insulating sheet is fixedly installed on the outer surface of the positive electrode and the second insulating sheet is fixedly installed on the outer surface of the negative electrode.
[0007] In a further embodiment, the positive electrode and the negative electrode are respectively connected to the positive and negative terminals of the power supply via electrode leads.

The piezoelectric ceramic achieves bidirectional sound generation through positive and negative electrode plates, while the insulating plate isolates both sides. Thus, this utility model can make great use of the transducer's energy, prevent energy waste, reduce the overall temperature of the transducer, and extend the transducer's service life.
