A remote control circuit(350) is implemented between the main body and the jack. The microphone terminal is connected to the microphone through a first signal line. The left speaker phone terminal is connected to the left speaker phone through a second signal line. The right speaker phone terminal is connected to the right speaker phone through a third signal line. The ground terminal is grounded through a fourth signal line. |
