Abstract: An earphone comprising: a device housing that defines an interior cavity within the device housing; an acoustic port formed through a wall of the device housing; an audio driver disposed within the device housing and aligned to emit sound through the acoustic port; a user input region disposed along an exterior surface of the device housing; a flex circuit disposed within the interior cavity, the flex circuit including a first portion bonded at a first location to an inner surface of the device housing directly beneath the user-input region, a second portion bonded at a second location to an inner surface of the device housing spaced apart from the first location, and a third portion extending between the first and second portions; a force pixel disposed within the interior cavity and mounted to the first portion of the flex circuit below the user input region; a plurality of touch pixels disposed within the interior cavity between the force pixel and the user input region; sensor control circuitry disposed w

Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.

Abstract: Improving the accuracy of ultrasonic touch sensing via the reduction, elimination and/or rejection of parasitic ultrasonic reflections caused by unintended touches is disclosed. The adverse effects of these parasitic reflections can be mitigated by disrupting the symmetry of the true reflections (from the intended touch) and the parasitic reflections (from unintended touches) so that the true touch can be disambiguated from unintended touches. Identification of the true touch can then enable accurate touch localization.

Abstract: Fabric touch-sensitive layers provided for electronic devices can absorb moisture, liquids or chemicals, which can cause drift in measurements of touch nodes formed in the fabric layer. In some examples, reference nodes formed in a fabric layer can be used to account for drift due to the absorption of moisture, liquids or chemicals. The reference nodes can be isolated from the effects of proximate or touching objects and from absorption of moisture, liquids or chemicals. The reference nodes can also be formed in a fabric layer having the same or similar properties as the fabric touch-sensitive layers. When measurements of touch nodes drift due to changes in absorption, the measurements can be adjusted based on measurements of reference nodes.

Abstract: This disclosure relates to touch-sensitive mechanical keyboards and methods for detecting touch events and key depression events on the touch-sensitive mechanical keyboard. The keypad can include a plurality of domes, a plurality of key make electrodes, first touch electrodes, and second touch electrodes. The first touch electrodes may be located underneath the plurality of key make electrodes, and the second touch electrodes may not. Both touch electrodes can detect touch events based on self-capacitance sensing. A key depression event can cause the key make electrode to make electrical contact with a corresponding first touch electrode, creating a short circuit that may cause the measured signal to saturate. The keyboard can include a plurality of sensing circuits coupled to the key make electrodes, the first touch electrodes, and the second touch electrodes. The plurality of sensing circuits can be used to detect both touch events and key depression events.

Abstract: An electronic device is configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. The localized haptic feedback is provided by an array of piezoelectric haptic actuators below the surface of the electronic device. Actuators within the array of piezoelectric haptic actuators are separately controllable by a control circuit layer. The control circuit layer includes control circuitry, a master flexible circuit which passes between rows of actuators, and an array of slave flexible circuits. Each slave flexible circuit is connected to the master flexible circuit and an actuator. In further examples, the array of piezoelectric haptic actuators provides a unified structure for detecting touch and force inputs.
