1. A keyboard, comprising:
- a key configured to actuate in response to a key press, the key including a key stack, comprising;
a key cap;
a key mechanism coupled to the key cap and configured to move the key cap between a rest position and a depressed position in response to the key press; and
a switch positioned beneath the key cap and configured to be activated in response to the key press; and
an output device configured to produce a feedback output comprising at least one of an acoustic output or a haptic output that is initiated in advance of the activation of the switch, wherein;
the key stack is configured to produce at least one of a sound or a tactile response as the key actuates; and
the feedback output combines with the at least one of the sound or the tactile response produced by the key stack to produce a single feedback stimulus.

Abstract
A feedback or a user-perceived feedback of an input device is modified using one or more output devices. The output devices include one or more speakers and/or one or more actuators. The output (e.g., acoustic and/or haptic) produced using the output device may enhance, amplify, mask, obscure, or cancel an inherent sound or tactile feedback produced by the input device.

7. An electronic device comprising:
-
a processing device; a keyboard operably coupled to the processing device and comprising a key stack, the key stack comprising; a key cap; a key mechanism configured to actuate the key cap between a rest position and a depressed position in response to receiving a user input; and a switch beneath the key cap and configured to be activated when the key mechanism is in the depressed position; and an output device;
wherein;the key stack is configured to produce at least one of a sound or a tactile response that is initiated prior to the activation of the switch; the processing device is configured to determine at least one of an acoustic output or a haptic output that, when combined with the at least one of the sound or the tactile response, produces a single feedback event; and the output device is configured to produce the at least one of the acoustic output or the haptic output in response to the user input to produce the single feedback event. - View Dependent Claims (8, 9, 10, 11)

12. An electronic device, comprising:
-
an input device having a movable key that is configured to actuate between a first position and a second position in response to a user input, the movable key comprising a key stack configured to produce a first sound as the movable key actuates, the key stack comprising; a key cap; a key mechanism coupled to the key cap; and a switch beneath the key cap and configured to be activated when the movable key is in the second position; and an output device configured to initiate a second sound prior to the movable key reaching the second position, wherein the second sound, combined with the first sound, results in a single feedback stimulus that is perceptible to a user. - View Dependent Claims (13, 14)

15. A method for operating an electronic device, the method comprising:
-
receiving typing activity at a keyboard of the electronic device; determining an identity of a user of the electronic device based on characteristics of the typing activity received at the keyboard, the characteristics comprising one or more of typing speed, force applied to the keyboard, or pauses between inputs; retrieving an input device profile associated with the user in response to determining the identity of the user; receiving a key press at the keyboard resulting in an activation of a key switch, the key press causing a key stack of the keyboard to produce a sound; determining, using the input device profile, an acoustic output that modifies the sound to produce a single feedback stimulus when combined with the sound produced by the keyboard a; and prior to the activation of the key switch, producing the acoustic output using an audio output device. - View Dependent Claims (16, 17)

18. A method for operating an electronic device, comprising:
-
determining that an audio output device is operably connected to the electronic device; retrieving an input-device profile associated with the audio output device, the input-device profile specifying a feedback output for modifying at least one of a sound or a tactile response produced by a key stack of a keyboard of the electronic device; receiving a key press at the keyboard resulting in an actuation of a switch, the key press causing the key stack of the keyboard to produce the at least one of the sound or the tactile response as the key stack actuates; and based on the input-device profile, initiating an output that corresponds to the feedback output, the output being initiated prior to the actuation of the switch and combining with the at least one of the sound or the tactile response to produce a single feedback stimulus. - View Dependent Claims (19, 20)
