Electronic Devices With Housing Port Shutters

Abstract

An electronic device may have a housing in which a display and other components are mounted. Audio components such as a speaker and microphone and other electrical components may be mounted in an interior portion of the housing. A housing port may be formed from one or more openings that pass through the housing. The audio or other component may be aligned with the housing port. A shutter may be interposed between the component and the housing port. The shutter may have an electrically controlled positioner for positioning a movable shutter member. The shutter may be closed by placing the shutter member in a position in which the openings are blocked, preventing intrusion of contaminants into the interior portion of the housing. The shutter may be opened by placing the shutter member in a position in which the openings are unblocked, allowing sound to pass through the housing port.

What is claimed is: 
     
         1 . An electronic device, comprising:
 a housing having a plurality of openings forming a housing port;   an electronic component in an interior portion of the housing; and   a shutter having a movable shutter member that is selectively placed in an open position in which each of the plurality of openings is unblocked and a closed position in which each of the plurality of openings is blocked to prevent contaminants from entering the interior portion of the housing.
