Abstract

A telephone device is disclosed. The telephone device has a base, a magnetic field generating device, an ear set, a magnetic sensor and a controller. The base has an ear set accommodating area. The magnetic field generating device situates with the base and generates a magnetic field. The ear set detachably connects with the base. The ear set has a magnetic conducted element. The magnetic sensor situates with the base for detecting the magnetic field. The magnetic field detected by the magnetic sensor is reduced due to interference of the magnetic conducted element when the ear set situates at the ear set accommodating area. The controller electronically connects with the magnetic sensor and determines whether the eat set is situated in the ear set accommodating area based on the change of the magnetic field detected by the magnetic sensor.
