As the time passes by, our devices are getting smaller, and the same thing goes for our speakers. If you're looking for a small form factor speaker, then we have the right thing for you called the Vol speaker.

The Vol speaker is designed by Hiranao Tsuboi and it's a rather simple device that combines speaker with a sound controller into one device. As for hardware details, Vol speaker measures 2.2 inches in diameter and 1.4 inches in height, it's made entirely out of aluminum and it comes with no buttons. Since it has no buttons, Vol speaker is turned on simply by adjusting the sound controller on the same way as you adjust sound volume. As you can see, Vol speaker is simple and sleek, and it comes in small form factor, so it's definitely a must-have device.

Although the Vol speaker looks amazing, it's not available for sale and will likely remain as a concept design, so we don't know when and whether we'll ever see it on the high streets.
