  • Low density electronic device
    Patent number: 10362699
    Abstract: An electronic device includes a display screen, one or more internal components, and a foam outer housing coupled to the display screen and enclosing the one or more internal components. The electronic device may also include a foam midframe enclosed by the foam outer housing. The foam outer housing may be resilient so as to provide impact absorption and water resistance, while the foam midframe may be rigid to provide stiffness to the electronic device. The electronic device may have a density less than 1 gram/centimeter3 such that the electronic device is buoyant in liquid water.
