Take a look at this little thread, core covered with the transparent tube, is it just a keychain ring?
Nope, it’s aerial of our wireless finger-ring.
It makes the remote control vibe:
Wireless range 10 meters;
Pulling force 10KG;
Besides, the little remote control vibrater is made from:
22 parts (not include the parts on PCB);
25 working procedure;
6 QC procedure;
Every little part is playing an important role in the finished wireless remote control vibrator.
There’s a long way to go before they arrive in the consumer’s hand.
