FIG. 1 is an external view of a device showing an embodiment of the present invention, which is divided into three parts: a radio/television receiver A, a wrist display B for displaying TV images, and a headphone C. Cable a and headphone cable b each serve as a broadcast wave receiving antenna depending on the usage state. First, when viewing television broadcast video and audio, the wrist display device B and the headphone C are worn on the wrist and head, respectively, and connected to the receiver A using cables a and b. Due to the elastic spring structure switch mechanism inside, only the headphone cable b is connected to the antenna circuit, and becomes an antenna for receiving broadcast waves.

In this embodiment, the audio signal line SR in the headphone cable and the ground line in the wrist cable are used as antennas. It goes without saying that ₁ , _B3 , and _B4 can also serve as a similar antenna mechanism by simply changing the circuit connection. however,
When the audio signal line SL in the headphone cable is used, the switch contact 18 is used, and when the ground line is used, the switch contact 19 is used. In addition, in FIG. 2, 12 is an intermediate frequency amplification/detection circuit, 13 is an audio intermediate frequency amplification/detection circuit, and 14 is an intermediate frequency amplification/detection circuit.
15 is an audio circuit, 15 is a power supply circuit, and L ₁ to L ₈ are high frequency decoupling coils.
