  • Patent number: 7746627
    Abstract: A portable electronic apparatus includes a housing and an output device configured to output sound. The output device is disposed on a surface on an inside of a slope disposed on a lower surface of the housing, the slope resulting in the housing being opened in a predetermined direction. The slope forms a space between the slope and a mounting surface on which the housing is placed. The surface on the inside of the slope includes a curved surface. The curved surface may be concavely curved relative to the bottom surface of the housing. The electronic apparatus may also include an input device, and the output device may be disposed on a side forward of the input device.

  • Patent number: 5802476
    Abstract: In a cordless telephone set, a base unit which itself has no loudspeaker function is made to provide a loudspeaker function at low cost. The base unit 2 has a transmitting circuit 22 for transmitting an aural signal and data to the handset 1 and a receiving circuit 23 for receiving and extracting the aural signal and data transmitted from the handset 1. A line interface circuit 25 coupled to a telephone line 3, a loudspeaker 44, and a selector circuit 28 for switching connection of the aural signal line between the transmitting circuit 22, the receiving circuit 23, the interface circuit 25, and the loudspeaker 44 are provided. In normal use, the transmitting circuit 22 and the receiving circuit 23 of the base unit 2 are connected with the line interface circuit 25 via the selector circuit 28. When predetermined push buttons 17 on the handset 1 are operated, the base unit 2 controls the selector circuit 28 so that the telephone line 3 is connected to the loudspeaker 44 via the selector circuit 28.
