high mechanical quality of the piezoelectric transducer

About high mechanical quality factor Q, it can improve the efficiency of the piezoelectric transducer(vibrator) and reduce the loss (7) Wide operating frequency band. In fact, it is difficult at present to have a piezoelectric ceramic material that satisfies all the above requirements at the same time. In practical use, piezoelectric ceramics transducers is necessary to choose according to different occasions and major contradictions. For the currently commonly used ternary and quaternary piezoelectric ceramics, piezoelectric ceramics can be divided into soft piezoelectric materials, rigid piezoelectric materials, and properties. Piezoelectric material between soft and hard by changing the mixing ratio and adding doping. low frequency piezoelectric transducer are polycrystalline ceramics obtained by mixing high-temperature sintering of solid oxides (zirconium oxide, lead oxide, titanium oxide, etc.) and solid-state reaction. Piezoelectric ceramics have a piezoelectric effect through DC high voltage piezo transducer circuit. The general ultrasonic receiver transducer is a functional ceramic material that can convert mechanical energy and electrical energy each other. Because of its good mechanical properties and stable piezoelectric properties, piezoelectric ceramics as an important force, heat, electricity, light Sensitive functional materials of piezoelectric vibration transducer have been widely used in sensors, ultrasonic transducers, micro-displacement devices and other electronic components. With the continuous research and improvement of materials technology, and electronic, information, aerospace and other high-tech fields With the rapid development, the production technology and application development of piezoelectric ceramics ring with high intelligence and new materials is a hot topic that people pay attention to.
