Patent ID: 8428670

Claim:
A reception device comprising: a transmission part including a plurality of stranded wire transmission cables configured to transmit a signal and/or power generated in a main-body device; an antenna part including a plurality of stranded wire antenna cables that are provided alongside the transmission cables from of the transmission part from ends of the transmission cables of the transmission part provided on the main-body-device side to a predetermined point between the main-body-device-side ends and the other ends of the transmission cables of the transmission part so that the antenna part and the transmission part form a path used to transmit a high-frequency signal; a high-frequency-elimination circuit that is provided in the main-body device and operatively connected to the main-body-device-side ends of the transmission cables, and that is configured to eliminate entry of the high-frequency signal from at least one of the transmission cables to the main-body device; and a tuner that is configured to operatively connect the main-body-side ends of the antenna cables to an antenna-input terminal and that is configured to receive a broadcast wave falling within a first frequency band, where the first frequency band corresponds to a length of the antenna part, wherein, the other end of the antenna are unconnected, the transmission and antenna parts stand in parallel and at a predetermined distance each other, a first stranded-wire part is configured as the transmission part and includes one ground line and two audio lines configured to transmit an audio signal generated in the main-body device to at least one speaker, a second stranded-wire part is configured as the antenna part and is connected to the ground line, the antenna part works as a first antenna used for a high reception frequency, and the transmission part and a cable of the at least one speaker work as a second antenna used for a low reception frequency.
