Abstract: An electronic device includes a housing and a buffer component. The housing has a corner portion and two side edges adjacent to the corner portion. The buffer component is embedded in the corner portion and includes a strengthened layer and a buffer layer. The strengthened layer includes an arc-shaped side edge and an embedded portion. The embedded portion is embedded in the corner portion, such that the arc-shaped side edge is aligned with the two side edges. The strengthened layer is a strengthened material structure. The buffer layer is disposed between the strengthened layer and the housing, and the buffer layer is an elastic material structure.

Abstract: An electronic device includes a housing and a corner structure. The housing is provided with a corner portion and two side edges adjacent to the corner portion. The housing includes an outer surface, an inner surface parallel to the outer surface, and a side surface located at the corner portion and respectively connected to the outer surface and the inner surface, wherein the side surface is a hierarchical curved surface. The corner structure is embedded in the corner portion. The corner structure is provided with an arc-shaped side edge that is aligned with the adjacent two side edges, one side of the corner structure, which is opposite to the arc-shaped side edge, is fitted to the side surface of the housing, and the corner structure is a reinforced material structure.

Abstract: A rotary switch with multi-level is disclosed. The rotary switch includes a rotary base that drives the first conductive sheet to rotate with the second conductive sheet when the rotary shaft is rotated, and the second conductive sheet leaves one of the conductive contact elements; the position end of the second conductive sheet is pressed by one positioning surface during the rotation, and the second spring stores energy; the second spring then releases the energy to the fourth end of the second conductive sheet, and the position end of the second conductive sheet slides on one positioning surface until the position end of the second conductive sheets is positioned solidly between two positioning surfaces; so that, the material cost in production can be lower down, and life time of the rotary switch can be increased.

Abstract: A variable focus device is adapted for focusing an image on an image sensing module, and includes a hollow fixing seat, a lens module and a lens coupling unit. The fixing seat is adapted for mounting the image sensing module therein. The lens coupling unit includes a piezoelectric layer and a metal layer disposed on the piezoelectric layer. The piezoelectric and metal layers are respectively formed with aligned lens mounting holes to permit mounting of the lens module to the lens coupling unit. The lens coupling unit is disposed relative to the fixing seat such that the lens module corresponds in position to the fixing seat. The piezoelectric layer deforms in response to application of a control signal thereto to move the lens module relative to the fixing seat, thereby varying a focal position of the lens module relative to the image sensing module in the fixing seat.
