COVER FOR A REGION OF A MOBILE PHONE

Disclosed are covers for a mobile phone including aspects that protect the phone from impact and/or provide shock absorbance characteristics. Covers can include one or more protrusions that reduce the contact surface to the phone and dissipate energy. Advantageously, the one or more protrusions work with intermittent spaces to provide shock absorbing characteristics and reduce the contact surface area between the cover and the phone. In some embodiments, the protrusions can include a soft-side rectangular shape, where the protrusions are placed in an ordered array in the back wall of a cover. In some embodiments, the one or more protrusions can include a row of x-shaped protrusions interspersed with air pockets along the inside wall of the cover.
