Abstract
The invention relates to a 3.5 mm audio plug with built-in light source, particularly to a light-emitting element arranged in a hollow tube and two conductive portions and several insulating portions arranged on a predetermined position of a surface of the audio plug for acquiring power and supplying the power to the light-emitting element in order to form a laser pen. At the same time, the electronic products are able to maintain normal output sound from a speaker when the audio plug is inserted into the audio jack of the predetermined electronic product, avoiding missed calls. Moreover, the audio plug is arranged in the audio jack except the light-emitting hole; that is, the present invention is nearly integrated with the smartphone 70, which is not only beautiful but easy to carry.
