Abstract: Described herein are electronic devices that includes a display stack having a cover component atop a lightguide component and a display component below the lightguide component. In some instances, the cover component including an antiglare etching applied to a top surface of a coverglass and a touch pattern applied to a bottom surface of the coverglass. In some cases, an optically clear adhesive layer formed from two types of optically clear adhesive may be located between the cover component and the lightguide component and a ring adhesive may be applied to around an outer edge of the cover component, the optically clear adhesive and the lightguide component.

Abstract: Various techniques are described for presenting haptic effects in a user device. The user device may include an outer shell and an inner device comprising one or more electronic components. The inner device may be suspended inside a cavity formed by the outer shell, and the inner device may be coupled to the outer shell by one or more haptic actuators situated between the inner device and the outer shell. The outer shell may substantially enclose the inner device, while leaving a touch sensor-enabled display accessible to a user. Based on touch inputs to the display, or other input events, control signals may be sent to the haptic actuator(s) to generate a relative motion between the inner device and the outer shell, the relative motion providing a haptic effect.

Abstract: Haptic effects are dynamically generated for content presentation on a device through analysis of the content. During content playback, audio data for the content may be analyzed to determine low frequency audio data. The low frequency audio data is mapped from a low frequency range to a haptic control frequency range of one or more haptic actuators included in the device. This mapping may be used to generate a control signal to drive the one or more haptic actuators. The haptic effects and the content may be synchronized to one another during the presentation of the content on the device. The haptic actuator control signal may be amplified proportionally to the amplitude of the low frequency audio data.
