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.

First claim

What is claimed is:

1. A telephone device, comprising:
a base, comprising an ear set accommodating area;
a magnetic field generating device, situated in the base, and used for generating a magnetic field;
an ear set, detachably accommodated in the ear set accommodating area, and comprising a magnetic conducted element;
a magnetic sensor, situated within the base for detecting the magnetic field, the magnetic field detected by the magnetic sensor being reduced due to interference of the magnetic conducted element when the ear set being accommodated in the ear set accommodating area; and
a controller, electrically connected with the magnetic sensor, and determining whether the ear set is accommodated in the ear set accommodating area based on a change of the magnetic field detected by the magnetic sensor.

2. The telephone device as claimed in claim 1 , wherein the magnetic conducted element blocks the magnetic field when the ear set is accommodated in the ear set accommodating area, such that the magnetic sensor is unable to detect the magnetic field.

3. The telephone device as claimed in claim 2 , wherein in the case that the magnetic field detected by the magnetic sensor is reduced or unable to be detected, the controller determines that the ear set is accommodated in the ear set accommodating area.

4. The telephone device as claimed in claim 2 , wherein the ear set comprises an answer end, the magnetic conducted element is situated at the answer end, and the magnetic conducted element corresponds in position to the magnetic sensor when the ear set is accommodated in the ear set accommodating area.

5. The telephone device as claimed in claim 4 , wherein the base comprises a base cover where the ear set accommodating area is situated, and the magnetic sensor and the magnetic field generating device are both situated at one side of the base cover, which is opposite to the ear set accommodating area.

6. The telephone device as claimed in claim 4 , wherein the base comprises a base cover and a bottom base case, the ear set accommodating area is situated at the base cover, and both the magnetic sensor and the magnetic field generating device are situated at the bottom base case below the ear set accommodating area.

7. The telephone device as claimed in claim 4 , wherein the base comprises a base cover and a bottom base case, the ear set accommodating area is situated at the base cover, and the magnetic field generating device is situated at the base cover or the bottom base case.

8. The telephone device as claimed in claim 2 , wherein the magnetic field generating device is a magnet or an electromagnet, the magnetic sensor is a Hall sensor, and the magnetic conducted element is a silicon steel or SGCC steel.

9. The telephone device as claimed in claim 1 , wherein in the case that the ear set detaches from the base, the magnetic field detected by the magnetic sensor is not reduced without being interfered by the magnetic conducted element.

10. The telephone device as claimed in claim 9 , wherein in the case that the magnetic field detected by the magnetic sensor is not reduced without being interfered by the magnetic conducted element, the controller determines that the ear set is not accommodated in the ear set accommodating area.

11. The telephone device as claimed in claim 1 , wherein the magnetic field generating device is situated adjacent to the magnetic sensor.

12. The telephone device as claimed in claim 1 , wherein the ear set comprises an answer end, the magnetic conducted element is situated at the answer end, and the magnetic conducted element corresponds in position to the magnetic sensor when the ear set is accommodated in the ear set accommodating area.

13. The telephone device as claimed in claim 12 , wherein the base comprises a base cover where the ear set accommodating area is situated, and the magnetic sensor and the magnetic field generating device are both situated at one side of the base cover, which is opposite to the ear set accommodating area.

14. The telephone device as claimed in claim 12 , wherein the base comprises a base cover and a bottom base case, the ear set accommodating area is situated at the base cover, and both the magnetic sensor and the magnetic field generating device are situated at the bottom base case below the ear set accommodating area.

15. The telephone device as claimed in claim 12 , wherein the base comprises a base cover and a bottom base case, the ear set accommodating area is situated at the base cover, and the magnetic field generating device is situated at the base cover or the bottom base case.

16. The telephone device as claimed in claim 1 , wherein the magnetic field generating device is a magnet or an electromagnet, the magnetic sensor is a Hall sensor, and the magnetic conducted element is a silicon steel or SGCC steel.
