Film-type haptic device, haptic feedback electronic device and haptic keyboard

An electronic haptic feedback device comprising:

• a case having an internal space formed therein;
• a plate shaped base plate received in the case;
• at least one spacer provided on an edge of an upper surface of the base plate;
• an actuator including a film shaped polymer layer positioned on the spacer and supported by the spacer and first and second electrodes provided so as to closely and entirely cover both surfaces of the polymer layer, respectively;
• and
• an elastic plate adhered to an upper surface of the actuator.

A haptic keyboard comprising:

• a plate shaped base plate;
• at least one spacer provided on an edge of an upper surface of the base plate;
• an actuator including a film shaped polymer layer positioned on the spacer and supported by the spacer and first and second electrodes provided so as to closely and entirely cover both surfaces of the polymer layer, respectively;
• a module for sensing key input adhered to an upper surface of the actuator and a user's key input;
• and
• a keyboard cover provided on an upper surface of the module for sensing key input, and having an upper surface on which a position of an input key is represented.
