Apple to create new headphone jacks

Written by Nick Farell


Smaller than the rest of the world
Fruity seller of proprietary toys, Apple has invented a new headphone jack which is smaller than those the rest of the world uses.

A new patent application from Apple was revealed this week by the U.S. Patent and Trademark Office and discovered by AppleInsider describes an audio headphone jack that depends on deflectable Pogo pins to conserve space. The application notes that audio jacks include several conductive pads in order to create contact with a standard 1/8-inch audio cable when plugged in. Through these cables, audio, power and data can be transferred.

Current audio jacks typically depend on "cantilever beams," which extend into the cavity and deflect away when an audio plug is inserted. The cantilever beam, however, can take up a large amount of space. "This can especially be an issue for electronic devices so small that the audio jack size effectively determines the size of the device," the patent says.

Because the new system takes up less room it means that the final device can be a bit smaller.
