Earphone antenna

An electronic system, comprising:

• a speaker;
• a speaker cable for supplying audio signals to the speaker, the speaker cable functioning as an antenna wire;
• a first pin jack connector portion on one end of the speaker cable;
• a shielded cable including a coaxial core, an insulation-coated signal wire for audio signals, and a ground wire, the coaxial core having a center conductor for transmitting high frequency signals surrounded by an insulator and further surrounded by a shield wire;
• a multi-pole connector arranged on one end of the shielded cable and adapted to electrically connect the shielded cable to an electronic apparatus;
• and
• a connection block for connecting the other end of the shielded cable to the speaker cable, the connection block including a circuit device for separating audio signals and high frequency signals, and a second pin jack connector portion for removably receiving the first pin jack connector portion to removably connect the speaker to the connection block.

An electronic system, comprising:

• a rod antenna;
• an antenna cable for supplying signals to the antenna, the antenna cable functioning as an antenna wire;
• a first pin jack connector portion on one end of the antenna cable;
• a shielded cable including a coaxial core, an insulation coated signal wire for audio signals, and a ground wire, the coaxial core having a center conductor for transmitting high frequency signals surrounded by an insulator and further surrounded by a shield wire;
• a multi-pole connector arranged on one end of the shielded cable and adapted to electrically connect the shielded cable to an electronic apparatus;
• and
• a connection block for connecting the other end of the shielded cable to the rod antenna, the connection block including a circuit device for separating audio signals and high frequency signals, and a second pin jack connector portion for removably receiving the first pin jack connector portion to removably connect the rod antenna to the connection block.
