Piezo-composite element

Application Theory:   Piezo-Composite transducers utilise the improved properties of ceramic rods embedded in a customised polymer matrix. This construction forms the basis for enhanced range capability and image quality of the complete transducer when compared to conventional monolithic transducer designs. It’s easy to take the sound adjustment with a sound wave incidence object because the sound impedance can control to low level. Moreover, an excellent characteristic like the adjustment of a piezo-electric characteristic, the emphasis of the vibration mode, and the effect etc. of the own dumping can be drawn out according to the volume ratio of ceramics.
