Abstract: The application provides a high-voltage interlocking device and method for detecting the high-voltage interlocking device. The high-voltage interlocking device includes a first resistance module; a first switch module, a second connection end of the first switch module being connected to a first reference potential through a third resistance module, and a control terminal of the first switch module being configured to receive a first driving signal, to enable the first switch module to be turned on or off; a second resistance module, another end of the second resistance module being connected to a second reference potential; a fourth resistance module; a second switch module, a second connection end of the second switch module being connected to a third reference potential through a fifth resistance module; a fault detection module, configured to determine a fault of the high-voltage component underdetection according to a first detection signal.

Abstract: An electronic device includes an enclosure, a display positioned with the enclosure and defining a front face of the electronic device, and a haptic actuator positioned within the enclosure. The haptic actuator includes a housing comprising a wall and a movable mass positioned within the housing and configured to move within the housing to cause the haptic actuator to produce a vibrational response. The vibrational response includes a first component within a frequency range and a second component outside of the frequency range and providing a haptic output portion of the vibrational response. The haptic actuator also includes a tuning feature incorporated with the wall and configured to reduce the first component of the vibrational response while substantially maintaining the haptic output portion of the vibrational response.
