Abstract: A keyboard of the present disclosure has a keyboard housing with a base plate defining a trackpad opening. The keyboard can also include a trackpad assembly disposed within the trackpad opening, the trackpad assembly including: a touch input plate configured to receive a user touch input and positioned above the base plate; and a flexure positioned below the base plate. In some examples the flexure includes: a first attachment portion attached to the touch input plate; a second attachment portion attached to the base plate; and at least one flexible portion connecting the first attachment portion to the second attachment portion and biasing the first attachment portion upward relative to the second attachment portion.

Abstract: An electronic device has a keyboard with an internal membrane. The membrane has a set of strain gauges configured to respond to a key press, such as when a collapsible dome collapses into contact with the membrane. The strain gauges are connected in a half Wheatstone bridge configuration and are positioned on the membrane in order to limit effects of temperature and subtle flexure of the membrane. The strain gauges are also configured to magnify detection of a resistance differential when a keycap is pressed with sufficient force.

Abstract: An electronic device such as a voice-controlled speaker may have an array of strain gauges and light-emitting diodes. The light-emitting diodes may be configured to display dynamically adjustable button icons overlapping the strain gauges. Force measurements from the strain gauges may be used to adjust speaker output and other device operations.
