摘要： An earphone includes a housing that defines a force input surface opposite a touch input surface. A spring member in the housing includes a first arm that biases a touch sensor toward the touch input surface. The spring member also includes a second arm that biases a first force electrode toward the housing and allows the first force electrode to move toward a second force electrode when a force is applied to the force input surface. A non-binary amount of the force is determinable using a change in a mutual capacitance between the first force electrode and the second force electrode. The mutual capacitance between the first force electrode and the second force electrode may be measured upon detecting a touch using the touch sensor.

摘要： An electronic device configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. A support structure is positioned below the surface, and one or more haptic actuators are coupled to the support structure. In some examples, the support structure is shaped or configured to amplify a response to a haptic actuator. When a haptic actuator is actuated, the support structure deflects, which causes the surface to bend or deflect at a location that substantially corresponds to the location of the activated haptic actuator. In some examples, prior to providing haptic feedback, at least one haptic actuator is electrically pre-stressed to place the haptic actuator(s) in a pre-stressed state. When haptic feedback is to be provided, at least one haptic actuator transitions from the pre-stressed state to a haptic output state to produce one or more deflections in the surface. In other examples, a haptic structure incorporates a piezoelectric element that is shaped to reduce the overall cost of the haptic structure while still providing high actuation performance.

摘要： An earphone includes a speaker housing; a speaker positioned in the speaker housing; a stem extending from the speaker housing, the stem defining an input surface; a conductive object disposed within the stem; a flexible circuit positioned between the stem and the conductive object; a member positioned between the flexible circuit and the conductive object operable to allow the flexible circuit to move with respect to the stem; a force sensor electrode disposed within the flexible circuit; and a controller operable to determine an input to the earphone using a change in capacitance detected using the force sensor electrode, the change in capacitance corresponding to a non-binary amount of a force applied to the input surface. In some examples, the earphone further includes a touch sensor electrode disposed within the flexible circuit.

摘要： 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.
