Abstract
An audio jack system includes a special audio jack adaptor that is particularly useful for digital players (e.g., cell phone, smartphone, MP3 player, computer, etc.) housed within watertight enclosures. When a headset is plugged directly into the digital player, the player's audio signal automatically goes to the headset, and the digital player's onboard speaker is silent. When nothing is plugged into the digital player, the audio signal automatically goes to the player's onboard speaker. When just the special adaptor is plugged into the player, the audio signal still goes to the onboard speaker; however, subsequently plugging the headset into the plugged-in special adaptor redirects the audio signal to the headset and not to the onboard speaker. To accomplish such results, a plug end of the adaptor includes a split-ring or split-tip set of open contacts that effectively close upon plugging the headset into a receptacle end of the adaptor.
