Microsoft wants to save the headphone jack from extinction

The 3.5mm headphone jack is officially on tech’s endangered species list, but Microsoft appears to working on a plan to conserve it for future generations.

Redmond has been granted a patent on tech that could help keep headphone jacks a part of ever-thinning mobile devices.

The patent, first reported by MSPoweruser, describes an expandable jack as a “plug receptacle for an electronic device.”


Essentially, it would devices to be thinner than the 3.5mm jack, yet still include one.

The port would slide out and expand, allowing a user to insert a wired headphone or speaker.

The site reports:

“By using an expandable headphone jack, the thickness of the body of a device is no longer an issue. A flexible jacket around a TRS or TRRS connector using spring loaded contactors makes the appropriate electrical connections and keeps a firm connection.”

Microsoft’s solution is shown in various potential forms within the filing that could prove popular among some tech fans.

A large number of smartphone manufacturers have ditched the 3.5mm jack, most notably the iPhone 7, 8 and X range.

Google’s new Pixel 2 devices dispensed with the headphone jack, but Samsung’s 2017 flagship phones kept it in place.

Whether OEMs would be willing to adopt this new technology remains to be seen.
