Thinner and lighter smartphones are easier to carry but render the sound quality capable from the built-in speaker to be quite weak, so the 'BumpOut' smartphone speaker is intended to help curb this issue.

The 'BumpOut' speaker features a stick-on design that can be placed on the rear of a smartphone, onto a laptop or stuck virtually anywhere one wishes. When utilized, the 'BumpOut' will instantly go to work to pump out tunes at a much better level than what's possible with the built-in speaker on your smartphone. This is because the 'BumpOut' smartphone speaker features an expanding resonance chamber that pops out when it's in use. This means the sound can resonate better to provide a louder experience without requiring oversized equipment.
