#1991: BuzzBud

I can’t believe how much energy my smartphone uses when it vibrates to alert me to the arrival of a new message.

This is a fairly brick-sized Galaxy Note, mind you, and the whole device shakes in my pocket.

Today’s invention is to supply such cellphones with an earbud containing a tiny, out of balance motor.

With the phone in a pocket, the ear piece could be worn in the ear or inserted into a shirt buttonhole.

A new message would only need to buzz a small external mass, thus being more discreet and saving my hard-pressed battery.
