You can eject the Samsung Galaxy Note 5’s stylus with your voice

The discovery was made by Patently Mobile who noticed that Samsung has filed such a design with the US Patent & Trademark Office. The diagrams clearly show how the system would work and enable the stylus to be ejected as required.
The mechanism relies on magnets. An electromagnet in the phone would be used to attract a magnet in Samsung’s S-Pen stylus, holding it in the phone when not in use.
TechRadar notes that the user would be able to use a special voice command or gesture control to release the stylus. Power would be supplied to the electromagnet so that it reversed polarity, causing the two magnets to repel each other and the stylus to fly from the phone into the user’s hand.

The stylus would be held in to the phone with a locking mechanism that would catch in a groove in the stylus, positioned between the main body of the pen and the tip. Samsung writes in the patent filing: “Since it is possible to automatically eject the touch pen only with a simple manipulation and/or command, it is easy to manipulate the electronic device with one hand, and since a separate locking device for confining the touch pen isn’t needed, it is possible to enhance the usage convenience of the electronic device.”
A notification such as a sound or vibration would let the user know whether the pen was released or not. The use of magnets would also provide a satisfying click when the pen was inserted, exemplifying the premium feel of the upcoming device.
The S-Pen has always been the standout feature of Samsung’s Galaxy Note range. A unique innovation that simply isn’t available on rival phones, the S-Pen makes note-taking, drawing and highlighting simple.
Fans of the Note range regularly say that “the only phone to replace a Note is another Note” and as such have been eagerly awaiting news of the Note 5 which should launch later this year, presumably including flagship specifications and the new-look metal design of Samsung’s Galaxy S6.
