A few months ago we wrote an article about a tiny speaker called the Mini-O. The Mini-O is the brainchild of four University of Notre Dame Undergraduates – Brian Cho, Peter Moeckel, Kunwoo Park, and Erikc Perez-Perez. The trio has partnered with South Korean patent holder HMLink to bring their magnetic speaker technology to the U.S. in the form of the little Mini-O Bluetooth speaker. In order to get the project off the ground, the young entrepreneurs attempted to crowdfund their Mini-O project on Kickstarter a few months ago. The first time around, they didn’t quite reach their goal, however, they’ve relaunched their Kickstarter campaign with hopes of finally bringing this diminutive speaker to the masses.


According to New Atlas, the speaker radiates sound by “transforming horizontal vibrations into vertical ones at a plate diaphragm”. As a result, the speaker’s balanced audio dispersion results in high-quality sound output while also utilizing a smaller form factor than traditional speakers.


Speaking of form factor, the Mini-O is small, very small. In fact, it’s just slightly bigger than a credit card and weighs only 72 grams which means it can easily fit in your pocket. The tiny speaker features Bluetooth 4.2 compatibility with a 30ft range. Each speaker has a power output of about 6 watts, but if you sync two Mini-Os together the combined 12 watts of power should be enough to create room-filling sound.


It’s estimated that each speaker should be able to play continuously for 4-6 hours on a single charge. Once all its juice is depleted, the Mini-O can be recharged in about an hour via its micro USB port.


If you’re interested in testing out the Mini-O you can head over to Kickstarter to preorder one, or maybe two. If they reach their goal of $10,000, the Mini-O is expected to begin shipping December 2017.
