    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: Electronic devices can include a textured exterior surface that is used for controlling functions associated with the electronic device or another electronic device when an object moves along the textured exterior surface. In some examples, the textured exterior surface can be a multi-directional textured surface to enable multi-directional touch functionality. In some examples, sensors of the electronic device can detect signal inputs generated by vibrations caused by the object moving along the textured exterior surface. The signal inputs can be processed to determine the directionality and/or speed of the movement input.

    IPC: H04R1/10

    Abstract: An electronic device such as a pair of headphones may be provided with ear cups having speakers for playing audio to a user. Capacitive sensor electrodes may be used in capturing capacitive sensor ear images that are processed by a machine learning classifier to determine whether the headphones are being worn in a reversed or unreversed orientation. The capacitive sensor electrodes may include grill electrodes that overlap at least part of a speaker grill, cushion electrodes that make capacitive sensor measurements through ring-shaped ear cup cushions that surround the speaker grills, and ring electrodes. The ring electrodes may be formed from metal traces on a flexible printed circuit. The flexible printed circuit may include a portion that wraps around each speaker grill and that is surrounded by a corresponding one of the cushions.
