Abstract: An electronic device may include a device housing and a display carried by the device housing. The electronic device may also include an actuator carried between the device housing and the display. The actuator may include an actuator body having an actuator bottom and a sidewall extending upwardly therefrom, a first guide member carried by the actuator bottom and spaced inwardly from adjacent portions of the sidewall to define a channel, and at least one coil carried by the sidewall. The actuator may also include a magnet being moveable within the channel and an actuator top coupled to the magnet and that includes a second guide member cooperating with the first guide member. The electronic device may also include a controller configured to drive the at least one coil to relatively move the actuator bottom and actuator top to thereby deform the display.

Abstract: A force transducer for an electronic device can be operated in a drive mode and a sense mode simultaneously. In particular, the force transducer can provide haptic output while simultaneously receiving force input from a user. The force transducer is primarily defined by a monolithic piezoelectric body, a ground electrode, a drive electrode, and a sense electrode. The ground electrode and the drive electrode each include multiple electrically-electrically conductive sheets that extend into the monolithic body; the electrically conductive sheets of the ground electrode and the drive electrode are interdigitally engaged. The sense electrode of the force transducer is typically disposed on an exterior surface of the monolithic body.
