Localized key-click feedback
First Claim
1. A keyboard comprising:
- a plurality of keys defined on a cover portion of the keyboard and configured to receive touch input, the plurality of keys being physical, non-actuating keys;
a first substrate underneath the cover portion comprising a plurality of suspended portions arranged on the first substrate to substantially correspond to a layout of the plurality of keys, individual suspended portions of the plurality of suspended portions being suspended from the first substrate by multiple connection points; and
a plurality of force-producing mechanisms underneath the first substrate, individual force-producing mechanisms of the plurality of force-producing mechanisms being positioned underneath the individual suspended portions; and
a second substrate underneath the plurality of force-producing mechanisms, the second substrate being electrically conductive and comprising a plurality of contacts, a contact of the plurality of contacts being configured to maintain contact with a force-producing mechanism of the plurality of force-producing mechanisms and deliver a drive signal to the force producing mechanism.

Abstract
Disclosed herein are techniques and systems for providing simulated, haptic feedback that is local to physical, non-actuating keys of a keyboard. A keyboard includes a plurality of non-actuating keys defined in a cover portion of the keyboard, a plurality of force-producing mechanisms coupled to a substrate underneath and adjacent the cover portion. The force-producing mechanisms may be positioned on suspended portions of the substrate that are mechanically isolated and arranged on the substrate to substantially correspond to a layout of the plurality of non-actuating keys. The force-producing mechanisms may be individually actuated to deflect the suspended portions of the substrate underneath the cover portion to create a tactile sensation for a user'"'"'s finger that is local to a particular key. In some embodiments, the force-producing mechanisms are piezoelectric actuators.
