Abstract: The present application discloses a speaker assembly. The speaker assembly includes a sound generator having a sound radiation surface and a back surface opposite to the sound radiation surface; at least one leakage area formed on the back surface; at least one leakage controller corresponding to the leakage area and covering the leakage area; a damping element disposed on a plane on which the leakage controller is disposed. The damping element is arranged between adjacent two leakage areas. By the configuration, the height of the speaker assembly is reduced.

Abstract: The present invention discloses a debris collection device for cutting mechanism and an LCD panel cutting debris suction device. A debris collection device for cutting mechanism comprises a debris collection cap and a suction spray head used for connecting with a suction device; the debris collection cap comprises a connecting part used for surrounding and fixing on the cutting mechanism, and the debris collection cap is provided with a through hole communicated with the suction spray head. The present invention can remove the debris produced in the cutting process in time, and can reduce relevant defects such as line scratches, terminal scratches, short circuit, broken circuit, etc. which are generated because of debris. Thus, the product yield and quality of LCD panels can be improved, and the time of the subsequent cleaning process can be reduced.

Abstract: The present invention discloses a test connector, a transmission wire, a test system, and a using method. A test connector for a low voltage differential signal transmission wire comprises a signal wire interface matching with the low voltage differential signal transmission wire, and a PCB interface matching with a PCB plate to be tested, and the signal wire interface is electrically connected with the PCB interface. In the present invention, the test connector is inserted or pulled instead of a low voltage differential signal transmission (LVDS) connection; when damaged, only the test connector needs to be replaced, and the service life of the low voltage differential signal transmission (LVDS) wire is extended greatly. Because the cost of the test connector is only less than 10% of that of the LVDS wire, loss cost can be reduced.

Abstract: A metal rolling mill having four rolls arranged in the shape of a cross for the purpose of rolling bar, wire, tube and other specially shaped metal rolling stocks. The roll system forms the core component and includes four rolls mounted on shafts placed at 90° with respect to one another. A single or set of double shafts transmit input or torque from a power source to the roll system and cause the roll shafts to rotate synchronously. The four rolls then press from four mutually perpendicular directions simultaneously on the same section of the metal rolling stock that is being fed through the rolls on the production line. The positions of these rolls can be collectively adjusted within their respective radial plane either mechanically via a remotely controlled device or manually.
