The wireless device 1 is composed of a wireless device main body 3, a hand microphone 4 including a locking piece 5, a locking member 6 to which the locking piece 5 included in the hand microphone 4 is locked, and the like. The locking member 6 and the locking piece 5 constituting the above are formed of a metal having conductivity. The locking member 6 and the wireless device main body 3 are electrically connected via a wiring member 7, and the locking piece 5 and the wireless device main body 3 are electrically connected via a cord 8. .

A constant voltage signal is applied to the locking piece 5 provided on the handheld microphone 4 from the wireless device main body 3 via the cord 8. By locking the locking piece 5 to the locking member 6, the locking piece 5 and the locking member 6 are electrically connected. Therefore, the constant voltage signal instructing the setting / cancellation of the HANG-UP function is detected by the radio main unit 3 via the wiring member 7, and the HANG-UP function is canceled.

When the handheld microphone 4 is removed from the locking member 6, the constant voltage signal applied to the locking piece 5 is not detected by the wireless device main body 3 and the HANG-UP function is set.
