Abstract:
1. A 3.5 mm audio plug with built-in light source, particularly to an audio plug matching the standard size specification of a 3.5 mm audio jack for acquiring power from the audio jack and supplying the power to an built-in light-emitting element and the audio plug, comprising: a hollow tube made of conductive materials and having a first conductive portion at a front section thereof, a first insulating portion at a rear section thereof and a 3.5 mm outer diameter; a light-emitting element having a base board, a light-emitting portion on the base board and a pin on a bottom surface of the base board and the above components being modular for the light-emitting element to be fully inserted into the hollow tube; an optical lens within the hollow tube located in a front of the light-emitting portion of the light-emitting element; a head being a cone body at a front end and having a joint portion at a rear end thereof for inserting into a front opening of the hollow tube, the head being out of a front end of the hollow tube matching the standard size specification of a 3.5 mm audio plug, the cone body having at least a part thereof forming a second conductive portion and at least a section of the joint portion forming a second insulating portion for isolating the cone body and the first conductive portion and the second conductive portion being electronically connected to the pin of the light-emitting element; and a cover body fixed on an outer side of a rear opening of the hollow tube; whereby when the audio plug is inserted into the 3.5 mm audio jack of a predetermined electronic product, the first conductive portion and the second conductive portion are respectively electronically connected to a second terminal and a first terminal arranged at a predetermined position in the audio jack for acquiring power and supplying the power to the light-emitting element; simultaneously, the first insulating portion is connected to terminals other than the second terminal and the first terminal in the audio jack for avoiding a sound outputting from the audio jack.
