摘要： A system may include an electromagnetic load, a driver configured to drive the electromagnetic load with a driving signal, and a processing system communicatively coupled to the electromagnetic load and configured to, during a haptic mode of the system couple a first terminal of the electromagnetic load to a ground voltage and cause the driving signal to have a first slew rate, and during a load sensing mode of the system for sensing a current associated with the electromagnetic load, couple the first terminal to a current-sensing circuit having a sense resistor coupled between the first terminal and an electrical node driven to a common-mode voltage and cause the driving signal to have a second slew rate lower than the first slew rate.

摘要： An electromagnetic actuator includes an inner magnet arranged relative to an axis, an outer magnet arranged a radial distance from the axis, an inner radial wall of the outer magnet facing an outer radial wall of the inner magnet, the inner and outer radial walls being separated by an air gap, a voice coil arranged in the air gap separating the inner and outer magnets, and an actuator coupling plate attached to the voice coil. During operation of the device electrical activation of the voice coil causes axial motion of the actuator coupling plate.

摘要： A bone conduction microphone is configured to convert vocal cord vibration into a sound signal. The bone conduction microphone includes a vibration collection unit configured to come into contact with a human body and collect vibration in a predetermined direction, which is included in the vocal cord vibration, and a switch configured to switch whether collection of the vibration in the predetermined direction is enabled. The switch is disposed on a side of the vibration collection unit, which is opposite to a side configured to come into contact with the human body, to allow a direction of an operation of switching whether collection of the vibration in the predetermined direction is enabled to be parallel to the predetermined direction.
