Abstract
The invention relates to an audio plug structure improvement, particularly to the audio plug coinciding with the standard specification of a 2.5 mm, 3.5 mm or 6.5 mm audio plug. The audio plug uses the composite structure of the conductive portion and insulating portion and the design of angle rotation to obtain power or signal without affecting normal use of the speaker of the electronic product. The ON/OFF switch is formed as long as the audio plug is rotated at a predetermined angle. Moreover, a predetermined electronic element can be arranged at the internal or external of the audio plug and the power or signal is obtained by the audio jack for having other functions except for transmitting the audio signal.
