ABSTRACT:
An audio jack includes a rectangular housing including a body including a rear first compartment and a hole extended from a front face to the first compartment, and an insulate plate secured to a top of the body; a plurality of contacts provided in the housing and including first, second, third, fourth, and fifth contacts each including a flexible portion and an upright solder portion; a light emitting element provided in the first compartment and aligned with the hole and including legs inserted through the first compartment; and a shell secured onto the housing. Inserting a first plug into the hole until the contact assembly is electrically connected with the plug will effect an analog signal transmission. Inserting a second plug into the hole until its head is electrically connected with the light emitting element will effect a digital signal transmission. The plate together with the shell can provide a double shield.
