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.

Abstract: A hard disk latch structure includes a hard disk base frame on which at least two receiving plates are formed. The receiving plates, each having a sliding groove with an insertion end and a blocking end, define a hard disk receptacle there between. The sliding grooves receive screws mounted on two lateral surfaces of a hard disk. As a hard disk is mounted between the receiving plates, a mounting element is further attached to one side of the hard disk base frame so that a plurality of blocking objects formed thereon lock those screws at the blocking ends, completing the assembly of the hard disk latch structure. The hard disk latch structure can be hook-mounted onto a computer chassis straightforwardly, which saves time and enhances efficiency of computer maintenance.
