Base station, wireless headset and headband thereto

1. A combination of a base station, a wireless headset and a headband, the wireless headset being mountable on said base station,

said base station comprising a cradle with electrical charging output contact points, a first surface-mounted magnetic means displaying a first magnetic polarization at said cradle, and a second surface-mounted magnetic means displaying a second magnetic polarization positioned adjacent said first surface-mounted magnetic means, said first surface-mounted magnetic means having an opposite polarization compared to said second surface-mounted magnetic means and being larger in size than said second surface-mounted magnetic means,

said wireless headset comprising attachment sites, a rechargeable battery, a cradle neck, electrical charging input contact points which contact said electrical charging output contact points when said cradle neck is mounted on said cradle, and a third surface-mounted magnetic means having a polarization that attracts to said surface-mounted magnetic means and is repelled by said second surface-mounted magnetic means, to properly position said cradle neck in said cradle so that said electrical charging input contact points contact said electrical charging output contact points, and

said headband comprising holding elements for said attachment sites, a cradle portion, a cradle neck which is mountable on said cradle of said base station, electrical charging input contact points at said cradle neck for contacting said electrical charging output contact points of said base station, electrical charging output contact points at said cradle portion for contacting said electrical charging input contact points of said wireless headset when said wireless headset is mounted thereon, and fourth and fifth surface-mounted magnetic means at said cradle neck having polarizations that cause attractive forces with the first and second surface-mounted magnetic means of the base station when the cradle neck of the headband is mounted in the cradle of the base station.

2. The combination as claimed in claim 1 , and wherein said headset comprises an electronics and housing part at a proximal end thereof, said electronics and housing part including a loudspeaker, and a boom arm that includes a microphone at a distal end thereof, and wherein the cradle-neck portion is located adjacent said electronics and housing part.

3. The combination as claimed in claim 1 , wherein the headband includes guiding surfaces at the cradle-neck portion thereof, wherein the headset includes guiding surfaces at the cradle-neck portion thereof, and wherein said base station includes guiding surfaces at said cradle thereof which cooperate with said guiding surfaces of both said headband and said headset.

4. The combination as claimed in claim 3 , wherein the first and second magnetic means of the base station are located at the guiding surfaces thereof, the third magnetic means of the headset is located between the guiding surfaces thereof, the fourth and fifth magnetic means of the headband are located between the guiding surfaces thereof, and wherein respective electrical charging and output contact points are located on opposite sides of a corresponding magnetic means.

5. The combination as claimed in claim 4 , wherein the guiding surfaces of the base station comprise two opposed protruding wall parts spaced equal to a width of the boom arm and the headband at cradle-neck portions thereof wherein magnetic means and electrical charging contact points are located between two opposed protruding wall parts.

6. The combination as claimed in claim 1 , including spring means to bias said electrical charging output points outwardly of said base station, and wherein magnetic attraction between the magnets at the cradle of the base station and the magnets of said headset or headband helps minimize spring biasing force required between respective electrical output contact points and electrical input contact points.
