Abstract: An electronic device may include a device housing and a haptic actuator carried by the device housing and that includes a haptic actuator housing and a field member movable within the haptic actuator housing. The electronic device may also include a motion sensor carried by the device housing to sense motion of the field member, an audio sensor carried by the device housing to sense audio noise from the haptic actuator, and a controller coupled to the haptic actuator, the motion sensor, and the audio sensor. The controller may be configured to drive the haptic actuator based upon sensed motion of the field member and audio noise from the haptic actuator.

Abstract: Locating a lost stylus, or other peripheral input device can be made possible by acoustic resonators integrated within housing structures of the stylus. Acoustic resonators can be formed at an end of the stylus opposite its tip, and can include portions of the stylus outer housing that are thinned down to an engineered thickness that has a particular resonant behavior or frequency. In some examples, acoustic resonators can be formed at a cap portion of the stylus, and can include a resonant diaphragm attached to at least a portion of a cap boundary. Cap coverings for the cap portion can optionally have openings to allow ventilation for changes in air pressure generated beneath the covering. In some examples, an electronic device can communicate a location request to the stylus and can cause the stylus to generate an acoustic signal for a specified target detector using the acoustic resonators.

Abstract: An electronic device may include a housing and at least one coil carried by the housing. The electronic device may include a field member that includes a magnetic body having a shaft-receiving passageway therein, and at least one bearing within the shaft-receiving passageway. A shaft extends through the at least one bearing and coupled to the housing to permit reciprocal movement of the field member along the shaft and within the housing responsive to the at least one coil. A controller may be capable of powering the at least one coil to move the field member after a threshold period of non-movement.

Abstract: Examples of the disclosure are directed to micro-machined ultrasonic transducers (MUTs) which can be embedded into a flexible band of a watch to detect touch, gestures, physiological signals, and transfer data. In some examples, the MUTs can include a piezoelectric material disposed between two electrodes and coupled to a base material having a plurality of cavities, to support motion of the transducer structure. In some examples, the MUTs can be coupled to multiplexing circuitry to stimulate, configure and control the MUTs. In some examples, the size, shape, and arrangement of transducers can be changed to improve characteristics associated with ultrasonic transmission. In some examples, the MUT array can be driven (e.g., by the CMOS circuitry) to beamform the transmitted and/or the received ultrasonic waves. In some examples, the one or more MUT arrays can be configured to generate haptic feedback via the flexible band.
