With regard to different versions of the device, it is expected that there will be Wi-Fi and LTE models (maybe with the Exynos processor). On the system side, it should carry Android 4.2.2 release. As for the release time, it is currently not clear.
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.
Yuhai support all the new developping transducer, Welcome the customized elements inquiry.
