An electronic device may include wireless circuitry such as infrared sources that control external equipment such as televisions and set-top boxes. An infrared source may be mounted within an electronic device housing in a visually inconspicuous location such as in a connector port. A button may be provided with transparent structures that allow infrared light to pass through the button. A removable accessory port may be provided with an infrared transmitter accessory that allows an electronic device to serve as a remote control device. Portions of an electronic device housing may be provided with thin housing walls or holes that are too small to be noticeable to the naked eye to serve as windows for infrared light. An audio port may serve as an infrared light window. Gasket structures, bezel structures, and the edges of displays and other planar glass members may be used in transmitting infrared light. |
