  • AUDIO PANEL TEMPERATURE CONTROL
    Publication number: 20230353936
    Abstract: A mobile device includes a panel audio loudspeaker including a display panel and an actuator coupled to the display panel. The mobile device includes a temperature sensor arranged to sense a temperature of the display panel, and an electronic control module in communication with the actuator and the temperature sensor. The electronic control module is programmed to perform operations including: obtaining, from the temperature sensor, data indicating a temperature of the display panel; and based on the data indicating the temperature of the display panel, adjusting a power signal provided to the actuator to drive the panel audio loudspeaker. The power signal can be adjusted by selecting, based on the data indicating the temperature of the display panel, a target temperature of the display panel; mapping the target temperature to a target power level; and changing the power signal provided to the actuator to the target power level.

  • Mobile device with proximity sensor
    Patent number: 8618482
    Abstract: A mobile device including a source for emitting electromagnetic radiation, an enclosure having a side wall, and a detector for detecting electromagnetic radiation emitted by the source is described. At least a portion of the sidewall is adapted to transmit electromagnetic radiation from the source. The source and detector are positioned inside the enclosure. The detector is spaced from the source, and is arranged to detect electromagnetic radiation from the source that is reflected from an object outside the enclosure and passes through the portion of the side wall.
