Whether you're tired of using your phone's camera to makeup or too lazy to carry bulky makeup mirrors, Mirra Mirra can meet your needs.

MirraMirra offers 4 different colors/styles to choose from, its built-in mirror has a very high strength, it will not easily break due to extrusion.

What's more, Mirra Mirra also provides lighting, even if the light is dim, it will not affect your look. Of course, this feature will also be quite useful for self-portrait lovers.

In fact, MirraMirra's lighting comes from the iPhone's flash, so it does not have its own battery, it will not consume the iPhone's power.

As a protective cover, MirraMirra itself is light enough and only 4.8mm thick. While providing additional protection for the iPhone, it does not make it unwieldy.

MirraMirra is currently crowdfunding on Indiegogo, starting at US$49 (about RMB 326), and is expected to ship in January next year.

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.
