MOBILE DEVICE ACCESSORY

原文（中国語）

An accessory case for a mobile device includes a housing, a channel, and an input board. The housing has a base wall and a perimeter wall extending away from the base wall, which together define a cavity to receive a mobile device. The channel is formed within the base wall, and extends inward from but not through the base wall to define a pocket that is separate from the cavity. The input board is received within the pocket. The input board is formed by folded segments that have one or more inputs. The input board is configured to transition between a folded position and an unfolded position. In the folded position, a width of the input board is less than a width of the channel. In the unfolded position, the width of the input board is greater than the width of the channel.
