Piezoelectric Elements For Inkjet Piezo Transducer

Piezoelectric ceramic ring



Applications: ultrasonic vibration tranducer for inkjet printer



Vibration mechanism of inkjet printer:

Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.

Piezo ceramics components features :

1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
