PITTSBURGH, Oct. 29, 2025 /PRNewswire/ -- "I wanted to create a phone or tablet case that would provide improved sound volume without the need for a separate wireless speaker," said an inventor, from Hidalgo, Texas, "so I invented the CANTU SOUND RE-DIRECTION CASE. My design would also offer a high level of physical protection for a mobile device."

The invention provides an improved design for a smartphone or tablet case. In doing so, it would re-direct the sound energy from the mobile device's built-in speakers out of the front perimeter edges of the case. As a result, it enhances sound quality. It also provides added protection against damage. The invention features a simple, practical, and protective design that is easy to use so it is ideal for the owners of smartphones and tablets.

The original design was submitted to the National sales office of InventHelp. It is currently available for licensing or sale to manufacturers or marketers.
