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.

Abstract: A key structure is applicable to an electronic device having a housing. The key structure includes a seat, a switch, a button, and an elastic sheet. The seat is disposed in the housing and has a first through hole. The switch is disposed on the seat. A key pillar of the button passes through the first through hole to abut against the switch. The elastic sheet includes a body, and a plurality of first elastic arms, second elastic arms and third elastic arms. The first elastic arms extending from the body are abutting against the housing. The second elastic arms extending from an inner edge of the second through hole are engaged with the key pillar. The third elastic arms abutting against the keycap are configured to support the button and provide a restoring force that can restore the button from a pressed position to an initial position.
