  • Publication number: 20240162218
    Abstract: An electrostatic discharge device including a gate structure, a plurality of first doped regions, and a plurality of second doped regions. The gate structure is disposed on a substrate. The gate structure includes a body part and a plurality of extension parts. The extension parts are connected with the body part, and an extension direction of the body part is different from an extension direction of the extension parts. The first doped regions are located in the substrate between the extension parts. The second doped regions are located in the substrate at two outer sides of the extension parts. The first doped regions and the second doped regions have different conductivity types.

  • Patent number: 10750265
    Abstract: The present invention provides a smart speaker with fragrance dispenser. A housing is disposed below a lid. One or more air outlet, one or more air inlet, and one or more sound outlet are disposed on one side of the housing. A fragrance module is disposed on the inner side of the housing for outputting fragrance. A speaker and the fragrance module are disposed separately. A dot-matrix display is disposed on one side of the speaker. The speaker outputs sound and the dot-matrix display outputs light. A processor is disposed below the speaker and connected electrically to the fragrance module, the speaker, and the dot-matrix display for controlling the output of fragrance, sound, and light. The present invention further adopts a limiting member so that the lid can rotate and slide on the fragrance module.
