Tactile Buttons Device For Removable Attachment On A Touch Screen

摘要

The present invention provides a tactile buttons device for removable attachment on a capacitive touch screen of an electronic device. The tactile buttons device is made up of a hollow, rigid housing and a plurality of resilient, deformable cones disposed on an upper member of the hollow, rigid housing, with each resilient, deformable cone for supporting a button. A film is disposed across a lower face of the hollow housing to define a lower surface, and a plurality of electrically conducting islands are disposed between the film and the buttons, so that each button is in register with both the associated conducting island and virtual button displayed on the capacitive touch screen. Momentary depressing each of the buttons activates the associated virtual button.

1. A tactile buttons device for removable mounting on a capacitive touch screen, the tactile buttons device comprises:
a hollow, rigid housing with a plurality of apertures formed on an upper member, with the apertures being arranged in a cardinal manner; a resilient bell-shaped cone is fitted in each of the plurality of apertures from inside the hollow, rigid housing; a button is located in a hole formed through a top of each resilient bell-shaped cone; a film is disposed across a rim of the hollow, rigid housing to form a lower face of the housing; and a plurality of electrically conducting islands disposed on an interior face of the film, so that each electrically conducting island is aligned with an associated button and is in register with a virtual button displayed on the capacitive touch screen, such that momentary depressing a button causes the button to make contact with the associated electrically conducting island, thereby activating the associated virtual button.
