Thanko to Launch a USB Ultrasonic Cleaner
Yesterday Thanko announced their USB ultrasonic cleaner, a cleaning device that uses ultrasound to clean delicate items like jewels, metal, and glasses…
Nothing special here, the USB ultrasonic cleaner is powered by two USB ports, and provides sonic vibration up to 5800 waves per minute.

at last, the ultimate usb gadget!
I’m getting that during my next trip there for sure!
5800 waves per minute doesn’t mean “ultrasonic”, infact it corrisponds at about 96Hz (wave per second), that is the hearable range.
You can refere to wikipedia for more info:

To talk about ultrasound we must have 1200000 wave per minute (20kHz)
Thank you
