Abstract: An audio jack comprises a housing and a plurality of contacts received in the housing. The housing defines a receiving hole along the longitudinal direction of the housing, and the face of the housing has at least an opening communicating with the receiving hole. The contacts at least include a deflectable contact and a fixed contact. The audio jack includes at least a dustproof film covering said opening so as to prevent the dust invading the interior of the audio jack.
