Digital units are sometimes designed with exact predetermined elements and customary to make sure consistency in consumer expertise. It has turn into more and more widespread for an digital gadget to be coupled with an adjunct reminiscent of a case. An adjunct can present extra advantages within the type of safety, improved look, and/or extra functionalities. Nevertheless, an adjunct may change the operation of the digital gadget and generally alter the consumer expertise and feeling of the digital gadget.
This paper describes varied embodiments associated to units, techniques and strategies that retain the unique tactile feeling of a button after an digital gadget is coupled to an adjunct that may change the tactile feeling of the button.
Apple’s proposed answer is, after all, written in patent-eze.
An digital gadget, comprising: a housing; an actuator unit carried by the housing; and a tactile compensation unit coupled with the actuator unit, whereby no less than a threshold actuation pressure to the actuator unit depresses the actuator unit, the edge actuation pressure defining a minimal pressure to depress the actuator unit, and whereby the tactile compensation unit features a triggering unit that kinds a magnetic circuit with a triggering magnetic aspect carried by an adjunct gadget that covers the actuator unit and offers an alteration to the edge software pressure, the tactile compensation unit offering, in response to the formation of the magnetic circuit, a compensation pressure that compensates for the alteration to keep up the edge actuation pressure.
However the thought, as seen within the drawing beneath, is to have a magnet contained in the button melancholy of the case. If you press the skin of the case, the magnet clicks towards the button itself, making a exact tactile click on which simulates the texture of the bare button.
As with all Apple patents, there’s no approach to inform whether or not or not the corporate will ever implement the thought, however this might be a approach for it to provide its personal instances a bonus over third-party ones that are usually considerably cheaper.
