    摘要: A vibration system which does not rely on adhesive assembly includes a first bracket and a vibration assembly. The vibration assembly includes a voice coil portion and a first diaphragm portion. The voice coil portion includes a mounting base and a voice coil body. The voice coil body surrounds an outer surface of the mounting base. Through holes define in one end of the mounting base. The through holes penetrate the base. The first diaphragm portion includes two connecting portions and a diaphragm body between the two connecting portions. A first connecting portion connects the first bracket. A second connecting portion surrounds an end of the mounting base away from the voice coil body, and the second connecting portion inserts into the through hole. The disclosure further provides a loudspeaker and a method for manufacturing the vibration system.

    摘要: A refillable ink box proofed against the formation of airlocks during filling includes an ink storage chamber, a seat, and an insertion tube. The box includes a bottom plate, and first and second side walls. The bottom plate and first and second side walls form the ink storage chamber. The seat protrudes to the exterior and carries insertion tube, ink outlet, and air guiding port. The insertion tube defines the ink inlet and also an air vent. The ink inlet communicates with the ink outlet port, the ink outlet communicates with the ink storage chamber. The air guiding port equalizes gas pressure with outside atmosphere and is positioned above the ink outlet.

    摘要: A naked eye 3D display device includes many parallax simulating apparatuses arranged in a straight line. Each apparatus includes a first image generating unit, a second image generating unit arranged side-by-side with the first image generating unit, and a light source facing toward the first image generating unit. First and second images are contrarily polarized and projected to the first image generating unit and to a second image generating unit respectively. A cylindrical barrier film faces toward the first image generating unit and the second image generating unit. Viewed from a first area, the first image is seen through the barrier film but the barrier film blocks the second image. Viewed from a second area, the second image is seen through the barrier film but the barrier film blocks the first image.

    摘要: An ink level detecting device rotationally coupled to an ink reservoir of an ink supply system is configured to detect an ink level of the ink reservoir. When an ink level of the ink reservoir is greater than a predetermined level, a weight distribution of the ink reservoir and the ink is toward a first side of the rotating portion. When the ink level of the ink reservoir is less than the predetermined level, the weight distribution of the ink reservoir and the ink is toward a second side of the rotating portion opposite to the first side.

    摘要: A high strength display device comprises a touch panel, a liquid crystal display, and a frame. The liquid crystal display covers the touch panel to expose peripheral edges of the touch panel. The peripheral edges of the touch panel are mounted to the frame, so that the liquid crystal display is mounted between the touch panel and the frame. A plurality of screw studs are formed on a surface of the liquid crystal display facing away from the touch panel. A plurality of first screw holes is defined in the frame, the plurality of first screw holes corresponds to the plurality of screw studs. The frame is mounted to the liquid crystal display through the plurality of screw studs and the plurality of first screw holes to add higher structural strength and durability.

    摘要: A fast-disassemblable display device includes a middle frame, a connecting plate, a backboard, an optical component, a display panel, and a bottommost frame. The middle frame includes a topmost frame, a left frame, and a right frame cooperatively defining a receiving space. The middle frame defines a sliding groove at inner surfaces thereof. The connecting plate is fixedly received in the sliding groove. The backboard is received in the sliding groove, and can slide into the receiving space through the sliding groove. The optical component is connected to the connecting plate. The display panel is connected to the middle frame, and positioned at a side of the optical component facing away from the backboard. The bottommost frame is connected to end portions of the left frame and the right frame facing away from the topmost frame.
