  • Publication number: 20170223460
    Abstract: A multi-way earphone may include: a housing having a space therein; a first sound unit housed in the space of the housing, and configured to convert an electrical signal into a sound; and a second sound unit disposed in a vertical direction from the first sound unit, and configured to output a different range of sound from the sound outputted from the first sound unit. The housing may form a first transmission path through which the sound outputted from the first sound unit is transmitted to the outside along the inner circumferential surface of the housing, and the second sound unit may include a unit cap forming a second transmission path through which the sound outputted from the second sound unit is outputted while being separated from the sound passing through the first transmission path. The stereo performance of the multi-way earphone can be improved to provide a sound with a 3D effect to a listener.

  • Publication number: 20040125953
    Abstract: In a broadcasting signal output apparatus and a method, an OSD processing unit produces a display-lock message if a display of contents is not permitted. A control unit determines whether the decoded video signal includes a copy protection signal for preventing the video signal from being reproduced, and if so, the control unit requests and receives a certification signal from the display device to determine whether the video signal can be transmitted to the display device through the video output terminal. The control unit then determines whether the certification signal corresponds with the reproduction preventing signal, and if it does not, prevents the decoded video and audio signal from being outputted, and controls the OSD processing unit so that the display-lock message is output to the display device (e.g., screen), so that the user knows when the currently received broadcasting signal is not displayed due to copy protection signal.

  • Patent number: 6219230
    Abstract: The present invention relates to a portable computer having a base and a display panel coupled by a hinge structure. The base has a bottom and a top housing. The bottom housing has bottom bosses with holes extending upwardly. A circuit board has holes aligned with the bottom housing holes. The top housing also has holes aligned with the bottom housing. A top housing is coupled to the circuit board and the bottom housing. A display panel incorporating a display screen is attached pivotally to the top housing with a hinge assembly. The hinge assembly has holes aligned with the holes of the bottom housing. A pair of caps are coupled to the top housing to cover the hinge assembly. Each cap has a boss with a hole aligned with the hole of the bottom. A screw is inserted from outside the bottom housing and through the circuit board, the top housing, the hinge assembly, and finally coupling with the cap boss. A single set of screws attach the base portions and pivotally attaches the display panel with the base.
