Abstract: A cantilever umbrella including a frame having an upper tray and a lower tray is provided. Two first crossed rods, a transverse rod and a first long rib are articulated to the upper tray. Two second crossed rods and two first short ribs are articulated to the lower tray. One of the two first short ribs is articulated to a middle portion of the transverse rod and the other one is articulated to a middle portion of the first long rib. A middle portion of each second crossed rod is articulated to a middle portion of the first crossed rod on a same side. An end of each first crossed rod is articulated with a short-rib tray which is articulated to a short rib, and an end of each second crossed rod is articulated with a long-rib tray which is articulated to a long rib. The short ribs each has one end articulated to the short-rib tray and another end articulated to a middle portion of one of the long ribs.

Abstract: An umbrella with a Bluetooth sound device, which includes a column having a top and a middle, a tray, a plurality of ribs, a canopy, a controlling handle disposed on the middle of the column and an electrical box having a involutory front cover and back cover. A solar receiving device is connected to the top of the column; a plurality of LED lamp strings is attached to the tray and the ribs. The PCB circuit board, the speaker, the LED lamp strings, the solar rechargeable cell and the umbrella are reasonably combined and fused into an entirety, thereby being very convenient to detach and install at the same time and convenient to change and maintain parts, the umbrella not only satisfies the daily sunshade and rain shielding of outdoor leisure facilities, but also has illumination, music playing, call answering and other functions, and is convenient to operate.
