An anonymous reader writes with an article on a recent patent application by Apple. From the article: "Apple likes thin devices and considers the depth of the iPod, iPhone and iPad as critical component of the aesthetic appearance of a product and has been very aggressive in finding ways to trim fat from its portable devices: The 3.5 mm audio-connector stands in the way of future design improvements: Apple suggests to simply cut it in half."

        You'll note that the patent (you did RTFA right? No, silly me, of course you didn't!) specifies that current connectors would be compatible with the port, but that either it would require a magnetic system to hold the connector onto the port, or a cover would have to be installed to hold the connector on, thus eliminating the need for an adapter since current 3.5mm jacks would work with it.

          Wrong. Current ports would be compatible with the new plug, but NOT the other way around.

          And there's already a more standard approach to this - 2.5mm audio jacks.

                Except, again, if you bother to RTFA, you'll note that the author clearly defines what he means by "jack" (i.e., plug), when he states "The audio jack consumes about 3.5, while the port and its ring add another 2.5 mm."

              • TFA isn't very clear, but the diagrams help. Apple wants to put the socket (receptacle, female*) at the surface of the device. Apple's new headphone plug (male part, found at the end of the headphone cable*) would be flush with the surface. Old headphone plugs also fit, but they would not be flush. Since the plug is only supported on one side, a magnet is needed to keep it from falling out.
                To compensate for the ugliness of having the connector exposed, Apple proposes to provide their headphone plugs with a

                  The actual patent states this to describe that figure: (well, what I could find [faqs.org], anyway - it doesn't include the figures, but it references the ones that were in TFA)

                  FIG. 8 is a cross-sectional view of a plug connector 800 mated with a low profile plug receptacle 802 that illustrates a magnetic retention mechanism according to an embodiment of the present invention. In the embodiment shown, plug connector 800 is similar in general construction to custom plug connector 400 of FIG. 4. For example, plug connector 800 can include a cosmetic cap 804. Low profile plug receptacle 802 is similar in general construction to receptacle 200 of FIG. 2A.

                  In various embodiments, low profile plug receptacle 802 can include a magnet 806 and plug connector 800 can include a ferrous attractor 808 (e.g., a ferromagnetic material such as steel). In one embodiment, the ferrous attractor 808 can be a discrete object embedded in the plug and/or connector body of plug connector 800. In another embodiment, ferrous attractor 808 can be integrated into the structure of the plug or connector body; for instance, the entire plug can be constructed of a ferromagnetic material.

                  In other words, a standard plug would fall out of the port, unless it was made from a ferromagnetic material or had a bit of ferromagnetic material embedded so that it would be held in the port by a magnet.

              Go read the patent. Jack is the same as a port. Here's what it basically proposes: Two types of ports. First is a half-port. Nothing will fit that new port except for the half plug. The second is a fully circular "port", but only putting the electrical contacts on one half of the the port. The other half (to make a full circle) is just a non-conducting part of the case of the device. This eliminates the contacts on the other half of the port, thus shaving maybe like a millimeter or two off the total

                I don't know if you have ever seen a internals of a jack. Basically you have 2 piece of metal, both with a rounded tips, hanging out. The metal act as a spring to apply tension pressure when the plug is inserted, maintaining a constant contact between the tips (remember the rounded tips?) and the plug (both the tip, ring, and sleeve). They usually have only 1 for the for each of the tip, ring, and sleeve. So essentially the design of the jack right now (in current production) are pretty much one-sided.

          • No, GP is correct, the new port will accept current plugs. They've sawed the port in half and put it at the surface of the device, so there's plenty of room for old cylindrical plugs.

        Because then the port would not be backwards compatible with 3.5mm plugs, which this one is.

        • by blair1q (305137)

          No it isn't. Not without some mod to the old port to keep the connector from falling out.

          The bigger issue I see is that a round plug prevents strain when the cord or plug is twisted. With this you're going to put a lever into your uber-expensive device, and either plugs will get broken off or cases will be sprung open.

          So the solution should have been something like a micro-USB shape, rather than this torque multiplier.

          • by RJHelms (1554807)
            It sounds like it is going to be on the side of the case, i.e. the flat part of the jack will be exposed. You're right that it will be a lever, except that the idea is that any force applied will make it just fall out.
          • by jo_ham (604554)

            The article addresses that - it is going to be a surface mount connector, that holds the plug magnetically sort of like the current magsafe design.

            The thin plug is presumably so that the overall look when it is connected will be flush, but the port will also take a standard 3.5mm plug too - it'll just stand proud of the surface, or (as also explained in the article, with a diagram no less) a 'cosmetic cap' would be fitted that covers the port. I assume that this will be part of the phone itself and work lik

Insert into the socket, alongside the busted bit using the spring loaded tab inside the socket to your advantage. Pull it back to remove the plug. It might take a couple minutes.

If you got all the manufacturers onboard, it could be good.

        I've noticed folks obsessing over a couple millimeters of thickness. I'm not really sure that 3mm of depth is really that big of a deal. Even with a cellphone, that's not really enough to justify the extra cost in most cases.

        What's worse is that this obsession with diminutive devices leads to devices that are less and less usable as they require fingers that are tiny to operate. At this point even if I wanted to buy an Apple device, many of them are way too small for me to use.

      The patented design allows semi-TRS plugs to mate with standard jacks, but does not permit the connection of standard headphones to the Apple design--what people will actually want to do, given the poor quality of the usual bundled earbuds.

      From my reading, a full male would work with this (the female end is basically like a trench or ditch on the outside of the device), just half of the connector would be sticking out and held in place al a magsafe, but a semi male probably wouldn't work with a full female, as nothing would hold it in contact.

      They could just move to a 2.5mm connector if it's that big of a deal, but devices have gotten to the point where there's little to be gained by making them any smaller. My Samsung Sansa is small enough that I have a hard time finding it if I don't put it back where it belongs when I finish with it. They could make is even smaller by removing the display, but it's hit the point of diminishing returns. And it sports a 3.5mm jack without trouble.

    Another advantage which they omitted from the article -- this invention will help you insert the plug the right way round.

    With the current circular 3.5mm jacks, it's actually impossible to know whether you've rotated the plug correctly. Sure, you can try to figure out if you've got it right by listening to the resultant sound quality, but that's inexact and most people don't even have the equipment. Now with Apple's invention, everyone will be able to insert it with the right rotation -- first time, and every time.

    • by jovius (974690)

      Exactly. It's great that Apple sells a device called iPolarizer to find the exact position. It works by aligning the electromagnetic fields of the connector and the plug to the same plane of reference. The effect lasts for a few weeks until you need to polarize the connectors again. There's also an app to visualize the process.

    • by scorp1us (235526)

      I really like the fact that the jack can spin. I can't believe they'd kill that feature for thinness.This means all plugs have to always be straight, or of 90degrees, plugged in the same way all the time.
