Handheld electronic device with integrated transmitters

An electronic device, comprising:

• a housing;
• and
• a button mounted in the housing;
• and
• an infrared source that emits infrared light through the button, wherein the housing has front and rear planar surfaces together having a first exterior surface area, top and bottom end walls together having a second exterior surface area, and left and right sidewalls together having a third exterior surface area, wherein the first exterior surface area is greater than the second exterior surface area and is greater than the third exterior surface area, and wherein the button is formed within an opening in the top end wall of the housing.

An electronic device that serves as a remote control that controls external equipment with infrared light, comprising:

• a housing having an audio jack port opening;
• an audio jack in the audio jack port opening;
• and
• an infrared source that emits infrared light through the audio jack port opening that controls the external equipment.

• a housing having an audio port;
• an audio component mounted in the audio port;
• and
• an infrared source mounted in the audio port.

An electronic device, comprising:

• a housing;
• a planar glass structure mounted in the housing, wherein the planar glass structure has peripheral edges;
• and
• an infrared light source that emits light through at least one of the peripheral edges.

An electronic device, comprising:

• a housing having an audio jack port opening;
• an audio jack in the audio jack port opening;
• an infrared source that emits infrared light though the audio jack port opening;
• and
